The Rifle is one of the "Long Range Rifles" that Len sells here on this site. It's got a 1/2" @ 100 guarantee. Brux #4 with 8.5 twist, Finished at 26" -- Stiller Predator action, Jewel Trigger that I set at 12 oz. Mcmillan HTG stock (used to be called the M40A1 I believe) For a Long Ranger, It's relatively lightweight, 8.5lbs before optics and bipod. Huskemaw 5-20 Blue Diamond scope, chosen for the weight and size. I could've put a Nightforce on it but it's a walking weight gun so I decided not to.
Using H4831SC, tried charges from 52 up to 56 grns and didn't see pressure but PoI began shifting once I got over 55 grns. Final load is set at 54.5 grns and average velocity over 3 chronograph sessions is 3015'/sec with the 140 Berger Hunting VLD seated .010 off the lands. Using a Federal Match primer.
I got during testing were 3/4" at 100. If I do my part it will shoot sub 1/2 MOA.......... Quite often, the first two shots cold bore at 100 would touch or overlap each other.
Here's some groups from last years load testing and drop verification, 1 @ 100yds and 1 @ 700 yds. This season I didn't shoot any groups, just a little practice on steel. For a "walking weight" rifle I have no complaints at all.
