Funny how the world works! Idk I've just come to the idea that some things just don't work for some people lol!
I like ball powders where they work and where they work they have worked better for me than extruded powders. For example, short barreled 06 loads I seem to do well, (21"-23"), with higher velocities, not that they don't do well with 26" barrels, they do, but they have always been better than extruded powders in short barrels.
In 30 Carbine I get great cold weather reliability, 100 FPS more with zero pressure issues and consistent extraction. In 45 ACP I get 1,050 FPS with 230 grain XTP and no pressure issues, that's 45 Super velocities, (beware, only for 45 pistols that fully encase the cartridge head). The 357 Sig can achieve full power European loads as designed, producing 1,500 FPS with 124 grain XTP, I run at 1,450 FPS. American 357 Sig ammo is awful. In my Glock 31 an absolutely fantastic CQB handgun combination.
My 06's in 03 and model 17, Remingtons with 24" barrels both can achieve over 3,100 FPS with 165 grain Hornady interlock and nearly 3,000 with the 180 grain interlock. That's factory 300 Winchester magnum velocities with zero pressure issues.
Now the accuracy considerations are not bench rest but these rifles are hunting rifles they produce at 100 yards 2 shots that touch and a third shot that spreads the group to about 1" from a cold barrel. With these rifles I've never needed a second shot, I know that today the big deal is 5 shot groups but in my opinion if I had to shoot at something 5 times tgat didn't shoot back I would rethink my processes.
