Would a muzzle brake help with control?

I agree with most of the posters that a good break will help with control, an for the same reasons as they list. But one thing to remember is that the added weight and length will effect the way your barrel vibrates and can change your point of impact. You may have to change your loading to get tight groups.

I have a adjustable break on a 7STW that lets me tune in my loads. I will pick a velocity and bullet type and adjust the break until the groups tighten up. It has worked very well so far.
