I would probably give up some recoil relief, but I think the trade off would be worth it for me. I am still looking at brakes, but sadly not much in the way of tech info on most I have seen so far.
James you do not want to attempt to thread your own barrel with a standard tap and die set. You cannot get it concentric to the center of the bore with them and could very easily end up with some serious issues such as the bullet actually hitting it.
Watch this video and it'll give you a good idea what all is actually involved in proper brake installation.
You'll find it's no where as simple as one would think.
Teacher is correct. There is a lot less of a noise issue with the SM brake than many others. An even better one for noise issues is the Shrewd Varmint brake available from Brownell's and I think Midway carries them as well.
I have one on my .260 and it's pretty damned neat. The ports o it do actually angle slightly forward at around 7 deg. No the recoil reduction is not as great with it, but I really like it especially on a rifle that I have to just grab and shoot quickly since if anything it's not as loud with the brake on as with it off.
Kirby's muscle brake I believe has a slight forward angle on it's rear ports. You can go to his site and check it out.
