I shoot a lot of long range (including many years of PRS competition), and I went away from suppressors on my long range bolt guns for the most part. I'll use them on my hunting rigs sometimes, but that's it. I did it for two main reasons:

1. I had instances with both quick detach and direct thread suppressors, where they would come loose at times during matches, and change my point of impact. This cost me match points on more than one occasion. Because of it, I found myself constantly checking the tightness, and finally decided to quit worrying about it, and went back to brakes.

2. Brakes have better recoil management, which makes it easier to spot impacts and misses.
