I don't like brakes myself because they will cause permanent hearing loss unless you have good double ear protection, you will **** off everyone at the range, any PH, guide, and your hunting buddies.
Use a Led-Sled with 100 lb. of lead at the range or wherever you target practice and work up loads. You won't really notice the recoil shooting a shot or two at game. This also allows one to develop a good shooting technique without flenching.
Week before last I shot 3 rounds of skeet (target loads). Shoulder was sore and purple. Last week I shot 50 rounds of 243, shoulder was sore. Same story with 308. When I shoot the 7mm mag at the range, forget about it! I use the Led-Sled for that and up.
Everybody is happy.
