Obligitory ramble first:
So I have a ruger m77 mkII chambered in .270. Has been my hunting rifle since i started hunting (bought it when i was 13). So i have done some improvements on it, had it floated and pillar bedded, and installed a timney trigger (absolutely a must for these firearms, and totally awesome). My latest addition to it is a Witt machine clamp on muzzle brake. Between those three modifications it is a total joy to shoot.
While I really like my Witt muzzle brake, it is quite heavy. The firearm has a slimmer (and 2" shorter) barrel than most other mkIIs, it was like a wand. Now its more like a... gun... had considered rebarreling with a schilling (local gunsmith does a good job and is super reasonably priced). But i have a hard time dropping that much on a hunting rifle to get target rifle accuracy (gun shoots about a MOA right now).
To run a screw on muzzle brake (lets face it, if i had a thread on it my next form 1 for a suppressor would be getting filled out pretty quick) the barrel would need to go on a lathe. Had a zaney thought though. Does anybody know of a tool to turn the end of a barrel while it is on the firearm? Thinking that a piloted hand reamer, or a contraption that would pilot off of the bore, mount to the upper barrel, and run off of a drill or something. Do any of these exist?
For the curious, i had to measure the barrel for my Witt brake, at the muzzle it is exactly .5" exactly a inch from the muzzle it is exactly .51". So it wouldnt take much to take it to say .4990 or so.
Seems a die like a crowning die (sorta) would be the most cost effective method.
