[QUOTE="J E Custom, post: 1033938, member: 2736"] I am quoting you because you have some good points that maybe I can help to clear up. #1= the minimum bore diameter should be no less than .020 thousandths larger than the bullet diameter. (Smaller than that can get dicey if the brake is not installed perfectly, and adds nothing to its performance). .030 thousandths is the maximum bore diameter before brake efficiency is reduced. #2= I cant attest to an accuracy problem with top vents, but I can show the results of what happens with them on VIDEO [media=youtube]_W4HviShfEs[/media] #3= There are many different types of brakes that ALL work to some degree, and none of them are quite. ear protection should be worn when shooting ANY firearm because My testing showed that DB levels are the same with or without a brake. Only the perceived sound is different because of the gases being directed in different directions. This VIDEO explains some differences in brakes and there function and efficiency is clear. with no mention of brands. [media=youtube]yBfPrlE5SX0[/media] also All testing was done on a machine that doesn't have any bias, it only measures recoil. A DB meter was used to check sound levels and was placed just behind the shooter for real world results. There are many opinions on what it takes to make a good muzzle brake. Only impartial testing identifies these differences, Not opinions. J E CUSTOM [/QUOTE]
