[QUOTE="IdahoCTD, post: 1710079, member: 13110"] The concussion doesn't really have to do with the side discharge or radial brake. It has to do with port angle. The more aggressive brakes have more concussion but they also reduce the most recoil. To answer your questions: 1 No 2 No 3 Not really. A good brush and powder solvent will clean them up but ultra sonic cleaners are easier. 4 Depends on the powder volume and powder used 5 Not all temp stable powders increase fouling. Refer to answer 4. 6 If you angle ports forward it will reduce less recoil but have less concussion. Angled back reduces the most recoil but has the most concussion. 7 Very rarely to they cause accuracy issues. Like maybe 1 in 1000. Most of the time people are more accurate with a brake due to the reduced recoil. This all is based on the fact that the brake is installed correctly of course. 8 Correct. A muzzle brakes doesn't change the velocity like a suppressor. 9 It is better to have the barrel threaded. Clamp on brakes work but they also tighten the bore or create a choke which isn't the best. 10 ???? I dont understand what your asking. The crown is unchanged. 11 My adjustable brakes work slightly better then my fixed brakes because they cant be turned down so I make the ports bigger in them. 12 The crown doesn't matter. There is no proof a 11 degree "target" crown is more accurate then a 90 degree flat crown with or without a brake. I pretty much laid out the workings of muzzle brakes in answering your questions. Ported or side discharge brakes are more effective then radial or drilled hole brakes. The direction of the ports effects concussion and effectiveness. Port design also effects the performance and the ability to control muzzle rise as do top ports. Top ports can be good or bad but are rarely perfect unless they are tuneable. [/QUOTE]
