[QUOTE="Trickymissfit, post: 1227700, member: 25383"] what's the difference between the Sharps and the older Copperhead? I know for a fact that the Army played around with a 6mm/45 using an 85 grain bullet close to 2800fps (there were all sorts of claims, and at least one was as high as 3100fps). As early as the Spring of 1968, there were well placed rumors of a .270 round under development. We always assumed it was off the .223 case. I have shot the 6mm/45 out of an AR using 80 and 85 grain bullets. Never checked velocity, but seemed to work very well. gary [/QUOTE]
