  1. Quality and affordable 5 Star Review

    Posted by on 5th Oct 2017

    I've purchased a number of barrels, this is the first large caliber (.338). I installed it on a 98 Mauser receiver and chambered it for a 33 Nosler. When we test fired the rifle at 100 yards with 3 rounds our group was under .250" I couldn't be happier.

  2. extremly accurate 5 Star Review

  3. 1903a3 .338/.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 .338/.300 winmag. I am obtaining 5/8 MOA and with 250 Berger bullets getting 2910FPS with H1000 powder in a trued 1903A3 action (sporterized), Timney trigger, Boyd laminated stock, glass bed free-float. Please not that these are compressed loads and had a 23 FPS max speed over 100 rds 2590 ft elevation and 89 degree day at 67% humidity

  4. 338 27 in barrel blank 5 Star Review

    Posted by on 11th Jul 2015

    I received this very shortly after my order, I took a week before I had time to gauge it. I upset a pure lead slug in the bore, pushed it through with a 5/16ths dowel, the groove to groove miked in within 2 tenths across six grooves at .338, the land to land miked in at exactly .333, with the slug pushing through the bore cleanly, smoothly, very even pressure, an accurate well rifled barrel.
