Can the "Boss Muzzle Breaks" be removed from Winchester and Browning rifles fairly easily, or is it a major job. I know the barrel could just be cut off and re-crowned, but that might leave the barrel shorter than I'd like.
I've got my eye on a 338, but it has the Boss installed.
You can screw it off, and replace it with a solid one. You still get the REAL reason the french developed these,.. you have a weight at the end of the barrel to tune the whipping of the barrel.
in fact, you will actually resolve at least as good as accuracy that the ported bos would
The Boss system on my M70 came with two units. One is solid and not a brake as mentioned above. There is also a locking nut that comes off and just leaves about 3/4" of threads.
Presently I have black tape on my threads. The rifle shoots the same with the Boss on or off but weights 1/4 # less without it.
There is not enough length on either units to turn one of them down to make a cover for the threads. I have not looked for a tap to make one but the threads seem very fine.
I may look for another M 70 and switch the barreled action and keep the Super Grade stock and bottom metal in order to get rid of the Boss.
they ain't pretty thats for sure- I would think it is just threaded on the end and I would THINK you could have something like a Barrel Dia thread protector made for it.
another thing that you can do is make a screw on front sight that covers those threads. I saw one that was done by Dave Gentry that looked really nice.
I had the same problem as you. I hated the looks of my BOSS even with the CR. So, I came up with the solution of taking it to my friend who is a machinist and he took the CR and shortened it to the same length as the threads after he put it in his lathe and turned it down to barrel diameter. He then bead blasted it, which is what Browning does to their barrels to get the matte finish on their stainless rifles and voila, no more BOSS. It shoots exactly the same too. It was a 1.5 inch 200 yard rifle before and after rmoving the BOSS. If you want someone to make you one, the threads are 9/16x24 fine thread. He was going to make one first out of a piece of stainless, but would have had to buy a tap that size as he didn't have one. If you have a blued barrel, you would have to blue the resulting cap after making the part. I am now happy with my resulting rifle again. After owning 3 BOSS equipped rifles, I have come to the conclusion that it is as easy or easier to get a non-BOSS rifle to shoot than a BOSS equipped one. I think my 300 win shoots more loads well now that the BOSS is off. I will NOT buy another BOSS equipped rifle unless it is very cheap and I can remove it easily. I just went and measured mine, it is 1.017 inches long, by .625 in diameter. The BOSS itself will not work well as there is not enough solid material without holes, you will need a CR for a solid piece.
By the way, on that 338 the BOSS is a larger diameter than the 300 win or 3006 models. I happen to have a CR in stainless for that 338 that I would sell cheap. PM me if interested. I didn't see at first that you had a 338. The threads on the 338 are larger that the 300 win mag so my measurement will be different.
I have a Blued Boss CR part # R720DM (It's the boss without the holes for a brake). The chart on the box lists that it is for the 300 win mag but I think it will fit on others too. If anyone needs this I will give it to them if you don't mind mailing me a check back for the cost of the postage. PM me if interested...........DJ

I will take that CR if it's not already promised. A PM has been sent.
What I will do is to put the adjusting nut back on with a turned down CR to just match the nut diameter and go to the end of the barrel. Thus the orginal system will be intact.
Savage99, if I remember right, the nut does match the diameter of the CR, and the CR is usually on just several turns from the end of the threads, depending on what setting you are using. So what you will actually be doing is shortening the CR an inch or so.
