I have two Savage 22-250's, the first is a model 12 FVSS with a 26" heavy barrel, the second is a lefty I screwed together with a 24" Shilen Select Match. Both are 1-12 twist and shoot Sierra 55 gr 1365's very well. One likes Varget and the other IMR4064. The 12 has a very nice bore and killed groundhogs out to 470 yards.
