[QUOTE="J E Custom, post: 1446479, member: 2736"] Rich, The tuning process is impossible for mass produced brakes because they are all machined the same and not for specific rifles/cartridge combinations. When I first started testing and designing muzzle brakes, I merely wanted to see if I could improve the recoil reduction over the best brakes available for on my rifles. the design took many turns and lots of things were learned by testing. each time we tested a new design we used the same rifle and load. We also tested the rifle without a brake first to benchmark the recoil in case anything had changed. The best brake we found at the time would produce 51 to 58% depending on the rifle/load combination. Puzzled buy this difference in performance I went back to the drawing board and tried to Understand why there was a difference in recoil using different cartridges. Each cartridge has a powder to gas ratio and there is the difference in performance. What I found was a way to adjust the brake to take advantage of this difference. once I understood the problem I had to develop a tuning formula for every combination of powder, bullet found in different cartridges. The results are surprisingly good and the percentage of recoil reduction is on average 10% better with the brake tuned for the cartridge/load combination than one that is not tuned. The fact that brakes that are mass produced are not tuned limits there performance. I am not in the business of making brakes so I don't have any ax to grind with any brake manufacture because even the poorest design reduces recoil which helps the shooter that is recoil sensitive. I only wanted to find out what makes a muzzle brake work and prove things that are wrong with many that reduce there performance. A Lot of muzzle brake designs target looks and tricks that appeal to some because of the WOW factor but in realty, don't do a very good job of reducing recoil.
