  1. 50 cal muzzleloader barrel 5 Star Review

    Posted by on 9th Jan 2021

    In my opinion you can’t find a better muzzleloader barrel for the price!
    Have used these barrels for yrs and they all shoot sub-MOA at 100yrds!

  3. best muzzleloader barrels out there 5 Star Review

    I have used green mountain 50 cal barrels exclusively for my companies High end muzzleloader. Especially for our high pressure smokeless Rifles, exceptional accuracy, very low runout for machining, minimal fouling. This will always be my go to muzzleloader barrel manufacture!

  4. Well machined barrel 5 Star Review

    Posted by on 24th Aug 2015

    I gave the barrel 5 stars only because it was exactly as advertised. It is very uniform. But it has several draw backs. First it is a 1.220 straight blank which does require a lot of machining to turn it down to a useable taper for a muzzle loaded. Second problem is the bore is .500x .510. There is really only one sabot I found that will work with a tight barrel likes this and that is the orange MMP Sabot. I would hope that GMT decides to turn this blanks into a nice useable taper. People will pay the extra money for that service.

  5. Inline Ml 5 Star Review

    Posted by on 5th Mar 2015

    I bought one of these barrels to build a ML on a Remington 700 action.I set it up to use a shortened rifle case using a large magnum primer.The rifle is extremely accurate .So far 2 shots -2 bull elk at 336 and 200 yards.I take the ml barrel off at the end of elk season and put my .308 bench rest barrel back on it so I can use the action until next elk season.
