I want to get a 338 can to put on a heavy sporter contoured barrel 338-06 and also use on a custom 308. It appears many are designed to work off of a muzle bread. I have a break on the 338-06 but not the 308. I think titanium would be best. It would be ideal to use on a standard threaded barrell without having to install a new muzzle break on each rifle. What are your suggestions. I was looking at the Wilson Whisper and the Desert Tactical Arms but both would have to have new breaks installed I think...
