Look around the web wherever you choose and you'll find the number one reducer in perceived recoil is not a gadget. Its more weight. I put weight in my A1 ad A2 stocks to balance the rifle right at the chamber. You can take the weight further, as in an active (moving) weight system and though it doesn't reduce the recoil energy content, it does lengthen its delivery out in time. That stretched impulse reduces the perceived recoil as its not so sharp. Though they help with muzzle climb, the impact of a muzzle brake is more appreciable with smaller bullet, large charge weight, bottleneck calibers such as the 7mm and 300 Win Mags. At least that's been my experience. I realize that retractable stocks ala M4 Carbines are more popular lately but they don;t leave many places to increase the weight and balance the rifle further rearward towards the chamber. Longer barrels move the muzzle blast further away from the shooter and encourage all the powder being burned before the bore seal is broke. While that reduces the recoil, it adds nose heaviness to the setup, necessitating offsetting weight in the stock to keep the balance more centralized. Just to clarify, I don't mean for the buffer to be misidentified as a recoil reducing active (moving) weight. I'm talking about spring weight inserts for more conventional A1/A2 stocks.
