[QUOTE="Trickymissfit, post: 468689, member: 25383"] well as many of you already know, I've been designing a few cases for a couple future chamberings. I've been playing around with a case that's built off a generic .243 case. The shoulder deminsion is 1.44, and case length is 2.00" with a 35 degree shoulder angle. The neck length is slightly longer than .31". The shoulder deminsion is .455. Bob Greanleaf did one that had a shoulder deminsion that was 1.368 long with a 30 degree shoulder. The case used a standard 2.045 case length. The round is 94% efficient, and about 70 fps slower than a .243AI with 107 grain bullets. Barrel life should be close to 2000 rounds! gary [/QUOTE]
