Hi all. I am looking for a bolt action .223. My question is if I go with a 1:7 or 8 twist rate to stablize heavier bullets at longer range how would a twist like that affect varmit bullets? Mostly will be used for target 4-600 yards, but may also pop the odd coyote at closer ranges. If not I still have an AR with 1:9 for those guys. Thanks.
