I would not muzzle brake the 30-06 as it's just too much noise. As suggested have a gunsmith fit a good quality recoil pad as that will make a difference for sure. When you are practicing you might try this. I like to wear soft plugs underneath my shooting muffs. Doubling up on the hearing protection is a great way to lessen the explosion that takes place when a shot is fired. Getting rid of some of that intense noise to me does make it seem like the recoil is not quite as bad. Another thing I do with pistols and rifles when shooting at the range is to take dummy rounds and alternate them in the magazine. It will show you right away if you are rushing or anticipating a shot, and by doing this it also helps you to concentrate and follow through with the shot. If the hammer falls on a dummy round and the sights don't move on the target you are "getting in the zone". You could have a partner load the magazines so that you do not know what you are chambering. This is excellent practice and you can do it on your own, yes even with just 3 or 4 rounds in a rifles magazine. Lots of dry firing helps too. You can do this at home and an A-Zoom snap cap helps protect the firing pin from being damaged. Just make ABSOLUTELY CERTAIN that you are using a snap cap and not a live round.
