[QUOTE="highdrum, post: 1558224, member: 13732"] 130fb is what blackjack uses on the 25x47 and 115fb on the 25 creed. Anything with a .300 neck and around 130fb. Shorter neck, longer freebore. If you send Miles Johnson @ blackjack a message, I'm sure he'll tell you bearing surface lengths, just subtract your neck length from the bearing surface, and that's close to the FB you'll need, add another 20 thousandths or so.
