[QUOTE="Trickymissfit, post: 646817, member: 25383"] Ackley stated that the plain jane 6x57 was about all the 6mm bore could handle, and we see this with a look in the reloading manuals as it's only good for about 150 fps more velocity than the .243. The Ackley version of the 6mm is about another hundred feet persecond at the most, but has an even better neck & shoulder design. Now you compair the 6/.284 to the 6mmAI and you don't gain a thing but new barrels. The 6-06 ought to be even worse yet! Probably the best would be a 6mmAI reamer ran into the barrel with a .243AI headspace. Or better yet a 6.5AI headspace. This would allow you to use the 57mm case length to form cases and yet have enough to allow for case shrinkage on fireforming. gary [/QUOTE]
