Re: Muzzle brake
J E Custom is exactly right!!!
I just had this same issue. I put on one of Steve Pratts titanium breaks on my 300 Ultra. I did find once I recieved the rifle back that the harmonics had changed. I made 3 shot groups from my original 84.8 to 84.4 respectively. Whouldn't ya know it, the gun shoots much better and the groups are way tighter (.25 @ 100) with a 84.4 grain powder charge. Now the gun shoots better than it did without the break. 4 thenths of a change made a dramatic difference. A part of me didn't want it to work out, I was dreaming of a new Brux barrel!! LOL!!
