See Cortex-A76OMG! 7nm! All day on a battery for smartphone or notebook! Huge performance increase over last year’s design! ARM is just about ready for anything ordinary users of IT need done. Put this technology into server-chips and we’re there.
I don’t know about you but I’ve been quite happy with my 28nm smartphone except for endurance, and the fact that my grandson lost it for me… At 7nm and improved architecture, I’m set for life. Put that kind of power into the servers on my LAN and the house will be humming. We are surviving at 35nm with a hair-drying AMD server now. By the time I get my Solo EV, I should have improved ARM technology running everywhere.

That beauty on the right is Berry’s Bullets .458 diameter 350 grain RSFN copper-plated bullet. It’s recommended for target-shooting and plinking up to 1700 ft/s muzzle velocity and they cost about the same as my typical 308 or 8mm hunting bullets. The core is not that hard and the plating not that tough so the bullet will distort or strip, I guess, beyond that. So, my objective is to develop a load that will give ~1700 ft/s out of the long (32 inch) barrel of the BC. A number of powders are suitable: Unique, H4198 and a few others. The problem for me is that much loading data is either more whimpy than that or far more brisk than that. I will have to experiment. I will also do expansion testing to see whether this load will expand on logs indicating usefulness on deer despite Berry not recommending these bullets for hunting. I figure if a bullet is soft enough to fail at 1700 ft/s near a rifle it will fail in a deer too. Lots of deer are taken with pure lead or hardened lead cast or swaged bullets and I doubt the thin plating of copper will make much difference.
I weighed ten bullets out of a bag of 100 and found the mean mass was 349.36 grains with standard deviation of .43 grain. The extreme deviation from the mean was 0.66 grain. That’s not as good as some jacketed bullets but at about half the price they should be just fine and probably better than cast bullets. A few of the bullets had small dents in the plating probably from shipping and handling.
First step is choosing a seating depth. BC is reputed to have a short throat but being a single-shot I don’t need to crimp on that cannelure or crimp at all and I will try seating out to the rifling right away. My loads will be far from maximum for such a strong action. I obtained some Starline cases. They don’t look as good as Winchester cases but they are cheaper so they are worth a try. They have ugly looking flash-holes seen from the mouth of the case but I made no attempt to true them. I made a tiny flare to avoid shaving copper and seated a bullet far out. I gradually seated the bullet deeper until the dummy round fitted easily about 0.050 inch from full insertion into the chamber. I then closed the action to seat the bullet further. LOA was 2.432 inch! That is a short throat! Typical loading data is for 2.55 down to 2.525 inch. I repeated the process, and noticed that I had judged chamber insertion by the extractor, not the chamber itself. Choosing smaller steps I was able to close the action easily at 2.461 LOA with rifling marks showing. The cannelure is just below the mouth of the case. This short throat will likely limit my velocity at the top end with 300 grain JHP just because of charge weight…
Lyman’s 45th cast bullet reloading manual lists 292 grain bullets with 18 to 20 grains of Unique and 385 grain bullets with 14 to 17 grains in an 1886 lever-action. Interpolating suggests 15 to 18 grains of Unique should work with a 350 grain bullet and give about 1500 ft/s in a 26 inch barrel and a bit more in a 32 inch barrel. I would risk a bit more powder given that my BC is much newer than 1886… The chronograph is my friend.
Those are scary loads… The charge only fills about ⅓ of the case so a double charge is easily possible. So, I weighed each charge and seated a bullet on it before I could accidentally add more powder. I labelled each case with Uxx.x to indicate the charge.
Next, I’ll load H4198. Hodgdon, who makes the powder, shows a “Trapdoor” load of 32 grains of H4198 giving 1483 ft/s for a 385 grain bullet out of a 24 inch barrel. It’s a very mild load at 14700 CUP so I should be able to use 35 grains in my BC with a 350 grain bullet. They show up to 54 grains behind a 350 grain bullet near 2100 ft/s for “lever actions”. Hornady published data for their 350 RN bullet, 34.7 grains IMR4198 for 1600 ft/s out of a 26 inch barrel. So, I loaded 7 rounds with 35 grains of H4198. Should be a hoot… 😉
“President Trump is imposing steep tariffs on steel and aluminum from three of America’s biggest trading partners — Canada, Mexico and the European Union.”
See Trump hits Canada, Mexico, EU with steel and aluminum tariffsSigh. Insanity is hitting your head against a wall because it feels good. Trump is on again with tariffs despite all kinds of good advice to avoid them. He claims the security of USA depends on having tariffs by a long chain of logic including boosting domestic supply while ignoring the fact that trade with Canada and Mexico is rather freely done. Depending on a reliable ally with a long border on land is not a threat to national security, idiot!
Further, it takes time to replace lost imports and prices will rise for the US consumer in a big way. Trump has already eaten up the savings his blue collar folks were supposed to get from cutting taxes in the hike in fuel costs. Add steel to that and it’s all over for the common man in USA. No soup for them.
Further, Trump is forcing Canada and Mexico to ship base metals to China and strengthening ties commercially. Can we say “self-imposed sanctions” boys and girls? That’s what Trump is doing, beating up USA to promote his ego, or whatever… He’s a traitor undermining all that is good in USA: rule of law, opportunity in markets, and security. Poof! They are all gone if this bozo is left to run the country much longer. Impeach the bastard!
“Zolpidem, sold under the brand name Ambien, among others, is a sedative primarily used for the treatment of trouble sleeping. It is typically only recommended if sleep hygiene is not effective. It decreases the time to sleep onset by about 15 minutes and at larger doses helps people stay asleep longer. It is taken by mouth and is available in a long acting formulation.
Common side effects include sleepiness, headache, nausea, and diarrhea. Other side effects include memory problems, hallucinations, and abuse.”
See ZolpidemI may not be a physician nor a pharmacologist but I’m pretty good at connecting the dots. Here are two dots that only became connected when Roseanne apologized for going nuts on Twitter:
- Trump appears intelligent to folks who know him but quite insane on Twitter. Is is schizophrenia?
- Trump apparently has sleeping problems and likes doctors known as the “Candy Man”…
Now, Roseanne admitted to similar insanity and claimed it was the effect of Ambien, a common sedative… Well, if Trump takes a dose to go to sleep and has been for many years, he might just be into the hallucinatory side-effects regime… So, now we have a conspiracy theory of our own explaining the irrational Tweets. It does not explain the doubling down on the nightmares of the previous night but that might be just laid at the feet of habitually refusing to apologize or to explain. Perfect, eh?
Yesterday, I removed tree seeds that were stratifying in damp soil in plastic bags in my refrigerator preparing to grow. I found some, like these Nanking Cherry seeds, had already sprouted and looked ready to raise their heads towards Sun. Other ambitious seeds included Manchurian Apricot. I wish other seeds were as ambitious but it’s all good. As long as we can grow new trees life will go on.

Here’s a picture of one of the ambitious cherries. Go for it, little guy!
Good fun. Buying the seed, waiting til February to begin stratification, and now putting them to the test is taking worthwhile risks because there’s nothing as beautiful as a tree, especially if it feeds the birds, the bees and me. 😉 Other seeds that took the plunge:
Amelanchier alnifolia, Hippophae rhamnoides, Parthenocissus quinquefolia, Prunus armeniaca var. Mandshurica, Prunus avium, Prunus serotina, Prunus tenella, Prunus virginiana, Thuja occidentalis, and Viburnum trilobum.
“Morneau said the project is in the national interest, and proceeding will preserve jobs, reassure investors and get resources to world markets. He could not say what additional costs will be incurred to build the expansion, but suggested a toll paid by oil companies could offset the costs.”
See Liberal government to buy Trans Mountain pipeline for $4.5BIs this the same government that’s planning to reduce CO2 emissions? How does that happen with greater extraction, shipments and burning of petroleum??? The last time I checked, global warming was global. We can’t export the problem somewhere else. My government should be in the business of cutting back on petroleum combustion, not investing in it. I’m buying an EV that will run on renewable electrical energy. Should I do that with one hand and promote burning of oil on the other? That would be schizophrenic. I’m not.
For the greater certainty, it’s not in Canada’s interest to have the world burn more oil. We should not contribute to the burden of CO2 in the atmosphere by promoting that in any way. We have an abundance of renewable energy. We should not feed other nations’ addiction to oil.

However you slice it, lots of people hate Trump, more than ever seen before, believe me… Have fun in November! NICE!
I did a few errands around the yard today: finished seeding some bare spots in the lawn, applied high nitrogen granular fertilizer and observed some germination on the last edge of lawn facing the road. The grass survived winter quite well and the new seeding is a bit weedy but dense enough to look good in a couple of years. The stuff seeded last year will be great next year. Where it’s not sparse this year, it’s already looking good. The fertilizer will encourage the grass to fill in a few smaller bare spots.
The established asparagus patch is quite productive even though it is only a few plants. Two whole rows I planted from seed will be productive next year if only I can keep the weeds at bay. Pumpkins, squash and onions are all doing well, the ones that survived our spring. The long range forecast is for normal temperatures but below-normal precipitation this summer. That means I will have production if I can keep the sprinklers going…
Trees took quite a beating last winter with little snow, lots of sunshine and high winds harming many trees great and small. TLW’s berms have lost several small bushes and one large spruce is brown. Her birch however is taller than I am and it’s right on the top of a berm of rather heavy soil. Now that the lawn is mostly established, more irrigation of the berms will help the survivors recover.
I did a quick inventory of my trees still in pots. I have a couple of nanking cherries that will be ready to plant out this year, a couple of poplars and a bunch of cedars. The next crop of trees is in the refrigerator stratifying and the cedars did well in a test-batch. We should not ever have to buy a cedar in a pot ever again. We have two days of light to heavy rain forecast. I expect I will plant the stratified seed in pots during that time as I won’t need to water anything and the ground will be muddy.
My long term strategy is to have way more Saskatoon berry bushes in the yard. With low germination and survival rates I may buy thousands of seeds and use the law of averages to make things happen. None of my Saskatoon bushes died over the winter because I have them mulched and sheltered. It may be my last accomplishment but I will succeed in this endeavour.
On a walk through the neighbourhood I saw that the majority of my neighbours have given up fighting dandelions. One yard has not even been mowed. I’m winning the fight but I don’t seen any end to the battle as long as paratroops keep up the invasion. Have glyphosate and 2,4-D, will fight on.
Trump must really get a chuckle out of how he’s cowed the news media and the Democratic Party. They both are not talking about impeachment nearly enough and the I-word is on the back-burner.
Look at the facts:
- Trump surrounded his campaign with evil men with deep ties to Russia. There was no earthly reason for that except Trump was beholden to a lot of Russians. Evidence clearly shows Trump, his organization and many of his trusted advisors were on the Russian payroll.
- Trump lied about nearly everything, burying the truth in such a deep bed of lies that few care about the truth these days. That’s dangerous and a complete betrayal of the US constitution which guarantees freedom of speech, freedom of the press and freedom of religion. Yes, Trumpism is a religion. Just look at that infamous cabinet meeting where many worshipped Trump openly while claiming Christianity and family-values and conservatism and republicanism.
- For the greater certainty, consider what a republic is supposed to be, a country wherein the ordinary people get to choose freely their government. There was nothing free and fair about the election. Trump lied fluently and the media spread those lies to the detriment of all other messages of truth and reason and righteousness and wisdom. Instead the Trump campaign was actively assisted by a foreign enemy of the state using every means available. Despite getting fewer votes than another candidate, Trump was chosen president. This was a betrayal of the USA by Trump, his campaign, his followers, the GOP, and even the Congress.
- Trump has also hired sycophants who undermine the departments they run, damage the natural environment, punish the innocent, and attempt to hold themselves above the law while doing do.
- So, now, Trump and his legions of liars are trying to undermine the rule of law, the courts, the FBI, the Department of Justice and the Democratic Party, to prevent correcting what needs correcting.
It’s time to trot out the I-word, now, before Trump is made King of USA. He’s lied to the USAian people and undermined the constitution and betrayed USA to Russia and Russian money. Those are high crimes. They deserve impeachment, jail time, and a real witch hunt to punish all those that colluded with Trump to overthrow law and order in USA. If the present congress won’t do the job they were elected to do, it’s now or never for USA to elect Democrats to run Congress in November and DO THE RIGHT THING!
UPDATE – Doing the right thing is not dead, apparently. One of Trump’s mutual admirers has been fired. Amen!
“Because there is still a fairly significant price premium on EVs versus similar ICE models, inadequate range on many models, and limited charging infrastructure in some markets, it is too early to worry about trying to convince mass-market consumers to make the leap to an EV.
That time will come beginning likely around the 2024–2025 time frame when EVs should be cost competitive and have an average range of 300+ miles.”
See Analyzing US Sales Trends For 24 Shared ICE/EV Models: Yes, Price & Range MatterOn the right is an excerpt from an otherwise good article describing adoption of EVs where there is a very similar model ICE or hybrid. On average, such vehicles get nearly ten times the market share between a particular EV and the whole market of cars. That’s because the maker of those cars has no bias towards the ICEd vehicle. He makes a lot of money either way. The reason EVs of similar kind to ICEs have higher prices is not that batteries cost more than ICEs but that the maker expects to earn a lot of money selling parts to fix the damned ICEs. Just try buying a brand new engine for your pet ICE! Mine costs about what I paid for the vehicle. That’s why folks normally buy a rebuilt or used ICE to replace an old engine.
Do the maths properly. Calculate the cost of fuel, maintenance and parts against the cost of an ICEd vehicle and EVs are the clear winners. Add to that the advantages of EVs not requiring warm-up, mufflers and all kinds of extra cooling and lubrication that ICEs need to keep serviced. My ICEd vehicle is costing about $5000 per annum to fuel and service. An EV may need to replace some moving parts but the ICE has far more moving parts so it’s not even a close comparison. I think depreciation is another factor that will eventually push people to EVs. After a few years, an ICEd automobile has lost half its value. At the moment, so do EVs but EVs likely have five years of trouble-free driving ahead whereas a used ICEd vehicles will likely need about as much in repairs and parts as it uses in fuel. Remember your refrigerator? Is it 10 or 20 years old? Who cares? It’s still running well because it’s electric and not trying to shred itself on every trip.
An ICE was a wonderful invention compared to horses and buggies but it’s outlived its usefulness. We have a much more efficient means of transportation with a further order of magnitude improvement in cost of operation compared to doing away with horses. I think EVs cost about five times less to operate in cost of energy and about that in repairs/parts too. It almost doesn’t matter what the purchase price of an EV is. If you drive it long enough you will be ahead in the game. My Solo EV will break even in about five years. After that, it’s performance is all gravy.
I am a little premature but I celebrated the demise of the ICEd (Internal Combustion Engine) automobile by watching the Indianapolis 500 mile race. It wasn’t as spectacular as some races in the past but definitely one of the safest. There were several wrecks where good drivers had their rear wheels slip coming out of a turn. Danica Patrick ended her career that way. There was no sign of an error by the driver but just that traction was marginal at the speeds they were going. There was a spectacular collision between a faster car and a slower car. The faster driver just could not avoid the collision even though the other car was going straight down the track. The winner was eventually decided just after a “restart” after yet another wreck.
Besides the usual fun of a race, I could not help being amused by the features of those ICEd vehicles:
- RANGE ANXIETY – supposedly a problem of EVs but it was palpable today. Folks were counting on wrecks causing “caution flags” so they could make a pit-stop for fuel and tires.
- FIRE – one car caught fire at filling and the driver drove off to kill the flames. The fire extinguisher at the pit was not available…
- NOISE – all kinds of folks were wearing hearing protection. ~12000 rpm reciprocating engines with turbo-chargers trying to shred themselves does that.
- CRAZIES – all kinds of folks were doing crazy manoeuvres during “restarts” because it was so hard to pass at full speed and not wreck.
- ALCOHOL – interestingly, the cars didn’t use petroleum as fuel but a mixture of alcohols. So much for BIG OIL stating we must use petroleum as fuel. That’s stupid. Other fuels are better and electricity is the best.
- FAST SERVICE – it was amazing that some pit stops took only 5+ seconds for four new wheels and a load of fuel.
Well, so much for the celebration of the peak of ICE for mobility. It’s too dirty, too costly, too dangerous, and too unreliable for my mobility. Hence my next vehicle will be an Electra Meccanica Solo, if EMV actually delivers the goods.
“Chinese automakers have symbolic export numbers, but the domestic market is more than enough to absorb current Chinese production capacity, helped by the fact that it is still a protected market and foreign OEMs haven’t yet looked seriously at this niche. With PEV quotas coming in the near future, foreign brands are finally putting in an effort, proof being that overseas automakers now have a record 7% PEV market share. Of this small cake, 3 percentage points belong to Tesla, 2 percentage points to BMW, and the remaining manufacturers share the final 2 percentage points.
In April, besides the continuous slooow production ramp up from BYD, registering its second-best month ever (13,200 registrations), small city EVs were back in the spotlight. Besides the usual BAIC EC-Series, the Zhidou D2 EV and the SAIC Baojun E100 also joined the top 5 best sellers of the month.”
See BYD & The Oompa Loompas Shine (China Electric Car Sales Report)There are two takeaways from TFA linked at the right:
- Chinese EV sales are growing wildly, and
- Chinese buyers have a huge number of choices.
This is fertile ground for innovation and I note that the top sellers are tiny city-cars, not unlike my Canadian favourite the Solo EV, which is being built in China by a well known maker of motor-cycles and small EVs. The BAIC EV-150 costs more than twice as much as the Solo but seats five. The Solo may be one of the first EVs exported from China and it will give the Chinese partner of Electra Meccanica a product likely to sell in China, India as well as North America and Europe. The next few years will be exciting as this herd of makers sorts themselves out.
