[QUOTE="trebark, post: 415696, member: 19172"] Ok guys....used some factory ammo last weekend to do the intial barrel break-in. In terms of copper fouling, the process went great. After shoot once, clean, shoot, clean, shoot, shoot, clean etc. through 20 rounds, the copper comes out of this barrel in one or two patches. In terms of accuracy.... not impressive. Got out to the range this weekend with some hand-loads.... Bullet: 142grain SMK Powder: 44.5grains H4831SC Primer: Fed210M Chronographed Velocity: 2730fps Load produced a .236" five shot group at 100 yards. [IMG]http://i342.photobucket.com/albums/o436/mtgrizzard/DSCN1174.jpg[/IMG] Also tested 45, 45.5 and 46 grains. The largest of group these loads was .75moa Hopefully will get some 140VLDs and RL17 to test soon. Want to get 2800fps with a 140grain bullet. [/QUOTE]
