[QUOTE="Bart B, post: 1809113, member: 5302"] 30-338's in 1:12 twist 28" barrels burning 5 grains less powder have shot 200 grain Sierra's into 5 inch 15-shot groups at 1000 yards. I think a 1:12 twist for your 300 Win Mag is ideal for bullets up to 220 grains. My 26" 300 Win Mag 1:13 twist barrel shot 180's and 190's into about 8 inches at 1K which ain't bad for an 8 pound hunting rifle [/QUOTE]
