I ordered my medium Palma 6.5x Bartlien Barrel for these new beauties, but wanted some input on a hypothetical best parent cartridge for this new bullet, specifically out of a mag fed bolt rifle.
Rifle purpose will be a trainer barrel that I swap out on my incoming Nucleus action with the barloc, already running a 308bf bolt.
I know this round is to heavy to run at the velocities it needs to shine, but I am still looking for exceptional barrel life.
I am considering the tried and true 22-250, per the Sierra data sheet I should be able to hit 3k FPS without difficulty, readily available and cheap brass, same bolt face as my 6xc, feeds well from mags.
Any other calibers im overlooking? Not wanting a AR optimized cartridge ie the 22 Valkyrie.
