I know how they work. But what I want to know. if I mill the end of my barrel to make a "muzzle brake" well it miss up acc of the rifle .all I am trying to do is get the muzzle jump down to a min on my step son's 243.
Just for fun of it if it can be done I am going to.do it to much 22lr as well
Well if you're going to do this yourself I would recommend knowing what tools you are actually using first of all. Second how do you plan to fixture this barrel? Deburr the inside of said slot? IMO do yourself a favor and pay a professional to do it correctly or leave it alone.
A man has got to know his limitations
