[QUOTE="Trickymissfit, post: 1000688, member: 25383"] actually that was a NASA project (22/378). The 6mm Vias (same basic case as the .224 Vias) will push a 70 grain bullet to 4200+fps. I know of no test shots with a 50 grain bullet, but do know that it will push 75 grain bullet (.224) close to 3900fps without even beginning to get into high pressure. (probably 4100fps max). Yet I'd rather have a big six than the .22. gary [/QUOTE]
