The "Camp Carbine" in 45Auto and some of the level action rifles in .357mag are also good choices.
For the bolt gun, or the enthusiast wishing excellent long range shooting, we smoke the bullet tip in an unpowdered cartridge (with a candle) at different lengths and arrive at the exact length where the bullet is just touching the lands. Makes a much more consistant jump that way from the case mouth to the lands, hence contributing to repeatable accuracy.
Then work up the power from a safe basic load up to perfect accuracy, which is not necessarily max load.
Many of the ultimate shooters actually use the military brass to load up the boat tailed bullets, as the brass is in fact thicker, with stronger case walls, and very uniform in weight per empty case. Just gotta be sure to load lighter initialy, as the heavier cases (thicker walls, same outside dimentions) will in fact, as you say, cause increaed chamber pressure, which among other things, greatly shortens servicable life of said firearm.
As a side, I did see charlie one time with a return spring sticking out of his cheek, musta had an overload :-))

If you use rifled slugs, you can reliably hit a man-sized target out to about 80 yards or so. And it will knock him down.
Other than that, I completely agree with you — a 12 ga is the single most useful and versatile firearm anyone can own.
whats the correlation between powder and rifling?
The other rifle that is very well built are the Swede Mausers in 6.5x55.
I corrected that brainfart in a follow-up post, as the shorter leade on the .223 causes the increase.
Yes, there is also the case wall thickness on the military brass being thicker, reducing the interior area, giving higher pressures with similar loads. Something to watch out for if reloading surplus brass.
Sweet. Made in Texas too and good prices.
I've done that very thing when loading rounds for my M1A Match rifle. I back it off about 5 thousandths or so and chrono them so the velocity is about 2650 or so. That way the rifle doesn't get beat to death.

I laid in about 3,000 or so rounds of Lake City 5.56 green tip a couple of years ago basically just for the brass. I had no idea that the stuff would be going for 800 bucks a thousand now. Hell, Mil-Spec 5.56 ammo was a better investment than my 401K!
At the time I was buying it for plinking ammo because it was cheap, about 189 or so a thousand DELIVERED. Try finding that deal these days. LOL!

I got one of the first 150 made, and I bought it cuz it is Tx made in Houston. It has been a very good rifle for me.
NO. The AK shoots 7.62x39 with a 123 gr .311 caliber bullet. The .308 is 7.62x51 with 145 gr .308 caliber bullet. The .308 is found in weights from 145 gr to 177 gr with the 168 gr HPBT being favored for long distance target shooting.
The first two values I cited were the common military/mil surplus types of ammo.
Nice AR’s there from the “show me” state. He includes two 30 round mags with them which is pretty good.
Very good prices too. I paid that for a Bushie back in 2000. Don’t mess with TX! Nice to see someone in TX making them.
I have not messed with the .308/7.62 in a technical way and would not comment off the top of my head on it.
I just built a varminter AR from a bbl blank up for myself. It shoots sweet! The hard part will be keeping the wife from claiming it.
The correlation is between bullet weight (affecting the bullet length when caliber is held constant) and rifling twist rate. A longer (heavier) bullet must spin faster to stabilize. A longer, heavier bullet may occupy some of the cast volume, thus reducing the amount of powder that will fit in the case. That gives an indirect relationship to "rifling vs powder". The choice of powder will also depend on speed of burning and powder density. The safest approach is to use a factory tested load book so you pick the right combination of powder weight, primer type, bullet type, bullet weight and cartridge overall length. There are many variables. The load book will give you safe ranges.
“Whatever you chose, make sure you practice, practice, practice. Get some training, too.”
This bears repeating. A firearm that you haven’t practiced with is almost the same as a firearm without ammo aka an expensive club. (Although this may not apply quite as much to a vet with lots of time shooting M16s transitioning to an AR, it’s still somewhat true.)
i wont be reloading my own. i mistook your weights in grains to be powder rather than bullet weight. thanks for breaking that down. bullet weight versus rifling makes sense.
Yes, and although “High Standard” has seen many changes along its business path, They have always had a reputation for accuracy. Their AR lives up to that reputation.
