My dear "handi' I'm the professional; your'e not. The attitude of safety is a top down consideration, period, end of sentence. It has nothing to do with the size of your caliber, that is unless people such as youself suffer from "caliber envy", then of course as a matter of logic [yours] it does.
Any line that allows a legally owned firearm to be used on it then must allow for muzzlebrakes to be used, whether its an M1D,AR-15/M-16 match rifle, or a M1A SuperMatch. If you are speaking of that, well then you must be speaking of yourself; I'm not overgunned. They all have muzzlebrakes, a muzzlebrake helps those of "us" who are good riflemen and who shoot "Expert" with "MasterPoints" and who have "Distinguished" to become better riflemen and to distinguish ourselves from those, even setting ourselves above them by our on line/on trarget performance, from mediocre and average riflemen who suffer from "caluiber envy", such as yourself.
