[QUOTE="Trickymissfit, post: 1037240, member: 25383"] Carmichael admitted it was a four to five hundred round case design many times. Hogdon list the MK.II as 4070fps with a 50 grain bullet, and the MK.II was a little faster. 42 grains of IMR 4064 with a 50 grain bullet is considered max, and that's also about 4060fps using a 27" 1:16 twist barrel. Would be a little slower with a typical 1:14 twist. It otherwords not a lot better than a 22-250AI, .220 Jaybird, and much slower than a .224 Vias. gary [/QUOTE]
