I've had amazing results with a Darryl Holland Quick Discharge muzzle brake mounted on a 7mm Remington Sendero. I had Guntech install the muzzle brake and he did an excellent job. At the range, the recoil is comparable to a 223 and you can spot your shots as they hit the target. While hunting, I've seen every whitetail drop in the scope. I use Peltor electronic ear muffs (added advantage of warm ears) or have plugs ready in the blind. I was so impressed with the recoil reduction, I purchased the newer brake from Darryl Holland and had Guntech install it on a Reminton LTR in 308. The reduction in recoil with the 308 wasn't as impressive as the 7mm but I think it may have to do with the fact of the 308 having less gas to counter act the recoil?
Summary....Quick Discharge and have Guntech do the install.
Side note. I purchased a JP muzzle brake for the LTR but couldn't install it for personal reasons ........beauty is in the eye of the beholder lol
Hope this helps in your consideration
