[QUOTE="Jeff In TX, post: 197486, member: 1522"] Well said. A muzzle brake will always change some aspect of your barrel dynamics. The real question is, is the change noticeable and even measurable? No matter the type of brake, design or even how well it’s constructed you’re adding additional length and mass to the barrel. Change is inevitable to some degree. The only way to know for sure is to document the barrel performance with and without the brake. This can’t really be done with one range session. Your cold bore shots may be different with or without the brake on. POI may be totally different with or without the brake. Usually any changes in velocities are so small they can’t be accurately measured. Some shooters develop a natural flinch when using a muzzle brake because the sound and pressures are directed back towards the shooters. I developed a flinch when I first started using a brake and I attributed a lot of the barrel changes to the brake and not myself. It wasn’t until I was videotaped and we played it back in slow motion that I saw I was flinching. I didn’t flinch with the brake, but I did when it was on. I had no idea but my brain and body were reacting to increased sound and pressures coming back at me. It took some work to correct it and to this day I don’t like shooting with a brake. Most of my rifles had a small POI change when the brake was on. Hope it helps [/QUOTE]
