[QUOTE="Trickymissfit, post: 724115, member: 25383"] at onetime I had two 77's chambered in 6mm with the nine twist barrels (I think they are closer to 9.5"). They really like 87 grain Hornadays and the 80 grain Sierra Blitz. Used H414 powder a lot. Seat the bullets about .005" off the lands, and in cold weather use a mag primer with the H414 and H380 powders. I tried 4064 powder, but the heat in the barrel was just too much for my likening. AA4350 and 2700 also work very well in them. My heavy barreled rifle shot 3/8's groups rather consistently, and light barreled rifle shot 3/4" groups with some bedding issues that I never took the time to completely fix. Have never seen a Ruger with a 1:12" twist. Are you sure that's correct? If so your pretty much limited to 80 grain and lighter bullets. The 105 grain Amax really wants a 1:8" barrel due to it's higher B/C. Niether of my rifles would shoot the 88 grain Bergers very well, but one would shoot the 69 grain LD's pretty good, but even then showed problems stabalizing them. Plus the throat is really too long for the 69 grain bullet anyway. The Sierra shot extremely well and was very hard on coyotes. gary [/QUOTE]
