I am and always have been a velocity junkie. The super hot 6mm will likely use a 1-8 Proof 22” barrel. I like the 6-284 because of the availability of Lapua brass.
I didn’t know this about you. I chase velocity (speed for our technical friends) & accuracy at the same time. Fast w/o accuracy is useless.
I take a 270 over a 308.... 7MRM over a 6.5x55..et.al.
I read a statement you made in hyperbole, « you’re looking to spit particles of steel out the end of the barrel »
lol, I’m close to that but not quite that extreme. grin
In prep for deer season — if I change loads or get a diff rifle ... I CHECK that 1st shot , cold bll. Regularly over the years I’m awed how well my rifles remain stable and the scopes don’t shift ZERO.
I have several rifles, diff cartridge, diff scopes and I’ve had to ADJUST the scope/s so SELDOM.
Good luck in your QUEST
