I think it was TWR that said after he changed muzzle devices, he noticed his rifle shot better. I also replied to his post and said I had seen it as well. So, something that may need to be added to the list is muzzle devices. I was at the range yesterday and wanted to try a different muzzle device on my 6.5 creedmoor. After trying the brake last week, I decided I did not want that damn loud thing on the end of my barrel!! So, I ordered a linear comp. I've used these before and they did make a difference with redirecting muzzle blast. The one I tried yesterday was no different, except I was surprised it seemed to reduce recoil a bit as well, compared to just having a thread protector on it. In all, I believe my groups shrank as well after switching to this style of muzzle device. Yeah, I know it sounds funny, but the rifle seemed to be more consistently accurate. Here are some pics from yesterday:
The rifle seemed to be more consistently accurate, if that makes any sense. Anyone else besides me and TWR experience this? Oh, by the way, this was just a cheap linear comp I bought from Ebay. Its called the XN 6.5 linear comp/sound forward muzzle brake.
