I am somewhat comfortable selecting bullets relative to barrel twist rates for 6.5 and 308 bullets. I came upon a Savage bolt gun with a 1 in 9" twist rate. I know that it should shoot 55 to perhaps 69 grain (maybe 75s) bullets quite well, but I am looking for actual experience with different bullet weights in Savage rifles with 1/9 twist rates. I would prefer to use Sierra match kings. This will help me get closer faster. Thanks
