When you get a belly like mine, breathing is always a problem…lol. Seriously though, I have found when shooting in the prone position that it works best for me to put my weight on my arms and keep my cheek off the gun or at least just barely touching. If I lay my cheek too snugly on the gun, I find that I am not as stable. Kinda the same thing at the bench, but when sitting it does not effect my shooting as much. Not that this is right or wrong, it just seems to work for me. I am open to new ideas too and can’t wait to see what others have to offer.
