[QUOTE="4mesh063, post: 26753, member: 941"] There may be a velocity gain but I'd bet the farm it's not 100fps or anywhere near. My gun w/wo brake makes no noticible difference in speed. I made a VERY tight brake for a 308 cal that was .315 ID and if it did help the velocity it make up for all that speed in accuracy. Shot terrible. I was told as Darryl says that .015 or so is the best number so I made a brake and tried it closer, .015 and opened up. I would say that .015 or more per side is fine. Another side note. The effectiveness of a muzzle brake is inversly proportional to the bullet weight to powder charge weight. In other words, a 220 swift is the king of recoil reduction and an efficient round, like a 7 BR or a 300 savage will benifit far less. A WSM lets say, will benifit, but not as much as your 300 weatherby. [/QUOTE]
