i think the first best step is to dial the rifle in. make sure it is zero perfectly.

shooting is one of those things where errors are cumulative. i am not even discussing "breathing" if we dont know without a doubt where the rifle is hitting.

sandbags or some type of lead sled thing. lock the rifle it..just be the trigger guy. you dont need to control breathing if you are on bags. i saw a guy with some apparatus that used a camera trigger thing on a cord to pull his trigger, he wasnt even looking down the scope anymore. that is extreme tho.
