The best recoil pad is a muzzel brake. LMAO!!
The second best recoil pad is a Limbsaver. I like them a lot. You can also buy a pad that you wear instead of the rifle. Alot of guys wear them at the range.
If you can handle the noise a muzzle brake is the way to go. It will take away up to 50 percent of the recoil if you get the right one. I like the looks and the performance of the Holland brake myself.
