Can't say whether you'll need a brake or not. Recoil is subjective. To me a .30-06 kicks! My .300WM is a Savage 112BVSS (single shot) and with scope it weighs in at 12lbs. I was doing load development today with it and a .260 Mtn Rifle (each end of the spectrum!) I shot it today 24 times with 180gn Ballistic Tips, RL22, 74gns and up. I also shot the .260 27 times. I'm really no worse for wear. The rain and night shut me down.
The Savage is a beast compared to the little Remington. After touching off 3 of those 180's, those little 100gn .260's feel like a pellet gun! LOL.
On the subject of breaks, they do substantially cut down felt recoil on the big boomers. I don't, however, like the blow back in my face some have. Just a matter of personal preferences I 'spoze. JohnnyK.
Thanks all! Well, I'll tell ya' what I'm gonna do after all the apreciated and helpful advice.....I bought a factory Winchester BOSS for the gun and the smith is threading the barrel for a brake with the same threading. This way I can practice with the brake, dial in the BOSS just before season for a little added accuracy and hunt that way. He is also making an end nut to take it all off. I haven't been able to find a factory BOSS black brake. Anyone have one out there?? It would be nice to keep it all Winchester.
Well sounds like you have a good rifle setup, but don't put the carrage before the horse. Long shots takes lots of pracitce. It is key to be able to put rounds on paper at similar ranges and conditions before taking game.
I used to re-load but now I "hand-load".
-- Well, at least I try --
For what its worth, I have a break on my 300 WSM. Works nice with little recoil pushing a 208 A-Max.

Thanks Britz. If I've heard anything loud and clear it's practice, practice, practice! Until reading this site I wouldn't have considered such shots on game. I'm inspired knowing its even dooable. I'm taking some of the first advice posted which was to buy the best set-up I could afford (which for me is 2k) ask lots of questions and learn from others, then do my time. I have never shot an animal in 25 years of hunting that I haven't recovered (save a couple grouse-tough buggers with the bow). I get a deer and/or elk every year and have absolute respect for taking ethical shots. I realize its entirely possible the gun will outshoot me and I wont be able to take the seriously long pokes. I'd rather know its me than my equipment! (If thats the case y'all might have a chance to buy a seriously nice rifle! I hope not!) You guys have been soooo helpful, and I must say I'm excited, and looking forward to continued communication and the good Lord willing-posting some pictures of long range success.
