[QUOTE="Long Time Long Ranger, post: 445349, member: 505"] The ones I tested actually increased velocity slightly, not decreased. A few years back there was a company called Montana Muzzle Brake. They claimed their brake would increase velocity by up to 100 fps. I seriously doubted that claim. I sent several rifles to them for brakes. This was back in 98-99 time frame when I was doing quite a few 338-300 ultramags, Lapuas and imp lapuas, 338-378's, etc. Several of the best 338 cartridges out there. The rifles with the Montana Muzzle brakes were the fastest of any of them I ever did. Some easily 100 fps outside the norm. For example one 338-300 ultramag with a 28" barrel was outshooting the 30" ones by quite a bit. One of my 338-378 wby's was shooting 300 grain bullets 3100 fps and 200 grain bullets over 3700 fps. I have never got those numbers in any 338-378 wby except the one with the Montana Muzzle Brake. Does anybody out there have any idea what happenned to those guys. I haven't seen the name around now in several years. [/QUOTE]
