I have a .223 pillar bedded and free floated in a Boyd's stock that has barrel venting, at the moment the rifle is mostly used for paper, plinking, and the occasional groundhog, however I want to keep accuracy at ~1 MOA or less. Someday I may rebarrel it with a varmint barrel however for now, what's a good practice as far as waiting between shots or groups? I have noticed that my 2nd shot often isn't as accurate as my first but I always just assumed it was me or something in my technique but now I'm beginning to question it. The barrel is 22" with a 1:8 twist and I shoot 50, 55, and 62gr ammo depending on the occasion.
