First Range Report
After six rounds of factory to zero the scope (that's really the extent of my "break in"), I settled in with some test loads with H4831SC and H4350. All were with 140gr Berger Hunting VLD, virgin Lapua brass, and CCI BR-2 primers. COAL was 0.004" off the lands, for a 3.132" OAL and 2.458" length to ogive.
Unfortunately, I think I started too low.
The best load with the H4350 was the top load I had, and it was progressively improving as I pushed the bullet more. At 47.3 grains of H4350, I was showing my best group at 5/16", and 2754 fps. The best load with H4831SC was 51.5 grains, 0.25" and 2817 fps.
Qualitatively, I love this rifle. Its balance and manners were perfect. It shot everything well, when I did my part, recoil was mild, and the barrel just wouldn't heat up. The last fifteen rounds I shot one right after another, and there was no drift and the barrel stayed warm. Those rounds also included the best group of the day (the 1/4" one).
I'm going to clean it up and load up another set, starting at the most accurate and working up a bit. I really think I should be able to find something closer to 3000 fps. Then I'll start playing with OAL.
I suppose I should be finding a decent hunting load and then just preserving barrel life, but this rifle is too much fun to shoot.
