I have read here that people tap the ports with filler screws. Port on, port off. Savage also offers an adjustable muzzle brake on some of their higher end rifles. Again, you can switch it of and on as wantred. I shoot at ranges where other folks shoot AR's and AK. In my area, a flash hider is illegal on most semis, so most people have Miculek and AK brakes, essentially the same as porting. Louder but you get used to it. A fellow club member shoots a Barrett 50. Ported of course, with no recoil and all blast kicking back 45 degrees. Once, while I was mounting a scope and sighting in at the next bench. I won't be doing that again....lol I was so jumpy, it was like I had 15 cups of coffee.
