  1. Great barrel for my CZ550 custom build 5 Star Review

    Posted by on 11th Feb 2019

    I used this blank on a custom built target rifle using a CZ 550 receiver. Immediately became my favorite for long range target practice. Neck sized reloads give 1/2 MOA groups. Factory ammo consistently is MOA or better.

  2. 308 blank 5 Star Review

    Posted by on 7th Feb 2017

    Very good quality blank... will have better review when machining and fitting complete. Blank as advertsised and shipping was prompt.

  3. Even better than I hoped for 5 Star Review

    Posted by on 25th Aug 2016

    As reviewed when this barrel arrived I was impressed with the quality and workmanship.Now that the barrel has been threaded,chambered and I have had a chance to shoot it I am even more impressed. Cast bullets shoot into an inch and 125 grain Nosler's are printing 5 shot groups under 5/8" at 100 yards. Who could ask for more?

  4. 1903A3 .300 Win Mag 5 Star Review

    Posted by on 22nd Aug 2015

    I turned and profiled these to match the contour of a 1903A3 rifle barrel but smith with no steps. I continued the profile to 27 inches and cut 1 inch off the muzzle (26 OAL), threaded and chamfered for a continuous line with a Shrewd #4 muzzle break for a .300 Win Mag. I am obtaining 1/2 MOA and with 210 VLD Berger bullets getting 2900FPS with H1000 powder 75.5 grn in a trued 1903A3 action (sporterized), Timney trigger, Boyd laminated stock, glass bed free-float. This combo gave exceptional accuracy and hit steal at 1200 meters with MRad 20x scope

  5. Exactly as described 5 Star Review

    I purchased this barrel to fit to a 1885 Winchester single shot in 30-30 Ackley Improved. The first thing I did was clean and bore scope the blank. I was very pleased with the interior finish of the barrel, I am not sure how Green Mountain can produce a barrel of this quality for this price but I am very happy that they do.
