Josh, thanks for the Shooter71 tip, now I know who to look for, 27 or 28 inches of barrel will be okay for this build, it wont be a walking hunting rifle, mainly back porch varminting, or as said earlier, throw it in a big Pelican and go shoot rocks with buds for beer ; ]
With the 6.5 PRC being basically a short magnum, a lot of bullet could indeed be left out of the case, something I hadn't thought about with the 6.5-06 and a standard M-70 mag box, I would be deep in the powder supply with some projectiles.
About the 131 Blackjack maker, I did some reading up on the 'Sierra' 150gr bullet in 6.5, not the best reviews, with some even reporting bullet blow up due to high twist barrels.
