For 308win, I m planning my 2nd ftr rig, that would also serve as a backup rifle. My current is 11t Bartlein 32" 5r, and I shoot 175smk and 185 juggernauts, saami spec. I have 200 and 215gr hybrids in mind for future, but would shoot the 175/185 for now. Would a 9 twist and 0.170 freebore be ok for these bullets as is (saami spec)? Would the 215gr hybrids fit in 0.170 freebore and still give me decent mv? I know, 175smk to 215gr hybrids is a wide range and not without some complication perhaps, but looking for the best compromise. The barrel is 1.25" dia at breach for for 5", and straight taper to 1" dia at muzzle, fluted for weight. I could order a 33" or 34" too, and still be under 18.2 lbs with a lightish scope and rings. Any benefits of going with more than 32"?
