Someday I hope to have as much free time to do physics experiments as Varmint Al does.

Ol' Al is a good guy. He's retired now, so he's got time. I used to get his political alerts, but they tapered off and I haven't heard from him in awhile.


I first "met" him (online) back when Pete :barf: Wilson was guvner of Kali. I don't remember how we got in touch. Al favored the legislation that created the current energy mess there - I opposed it. We hammered back and forth by email for quite a while - all in good spirit. Took him a long time to admit he was wrong! :D


But he's sure got some cool stuff on his site. 'Specially if you're of a scientific bent...



BTW, that should be "effect on brass cartridge case ", not "affect".

Hmm, could be...sometimes the line between Affect and Effect becomes blurry.

Nope. Not understood by many (thanks to our dumbed down school system of the last 50 years), but the difference is nonetheless clear. This should have been "effect".



Google + "affect vs. effect" = 10 seconds =

This article makes me wonder what kind of guns (chamberings) we'd have if those supercomputers were working more on this stuff and less on figuring out the weather.

Hmmm. Not sure how that would work out.


"The forecast is for 2250 fps muzzle velocity, followed by scattered powder burns at close range, giving way to 1" groups at 100 meters.

Later this week we'll see some light pressure testing, with CUP readings in the 30,000 range.


We'll have more on that new shoulder angle at eleven. Back to you, John!"


:D

It certainly makes for interesting reading, doesn't it? Even if it is untimately acedemic, it is enjoyable none the less.
