Try some 760 . Im getting 3643 with a 75 g berger VLD.Really the only reason would be not having to fire form. My dad built a 22-250 AI with a 7 twist shilen. Currently the barrel is back to shilen(again) as we can't get anything below moa. He says if he could he'd rather the 22 creed just because he doesn't like fire forming. If it was me, I'd stick with the 22-250 AI. It should have a slight edge over the 22 creed. Brass is everywhere. Initial load development with rl-26 yealded 3550 with a 75 grain eld.
So, given that the 22-250AI can be easily done and chambered, why would one bother with another round that does the same thing but with proprietary components? I'm looking to do a hot 224 for when my 260 dies. I'd like to run the 95gr SMK for long range low recoil. With a .600 G1 bc, I can't over look it.
So, when the 22-250AI will run the same speeds as the 22 creed, with much easier to find brass, barrels and dies, why would I want to go creed?
Quality cart will make you head stamped brass.Hmm ! Where can you FIND 22-250 Rem AI factory brass with the correct headstamp ?? WP
