Hey jaw719, I have a Wby 300 in a Rem 700 and after 30 years of shooting it, I finally had a brake put on it. I put an APA 4 port answer brake on it, I have the first 4 UDP ports closest to the barrel opened. I just shot it that way the first time last week. I saw the dirt kick up behind the target when I shot. I also have a 6.5x300 Wby in the Mk V ULW, it has the radial Wby brake. It's an ok brake but you will not stay on target with that brake. There is recoil reduction for sure with the radial brake. I have shot the 6.5 without hearing protection on my caribou hunt this year, it was running and I didn't take the time to put them in. I don't think I'd want to do that with the 300. I'd take the 300, especially if you shoot it well and have total confidence in it. When it's been a serious hunt and stuff needs to die, my 300 is what goes. Good luck!
