I took two different bullets to the range to chronograph and ran into a couple of guys that shoot at 1,000 yards. I was in the middle of the recommended range. They suggested making up loads and incrementing the powder in .2gr and speed checking. There would be a sudden drop in velocity variation, which is the powder I want for that bullet/rifle. They also suggested going to 63g instead of the 55 I had purchased. Barrel twist rate is 1/9. Long term plans include suppressor and procuring an AR pistol. I have no plans to get into long range shooting. Are the instructions good? How bad will the performance be with shorter barrel? Is ten rounds enough to make a determination? Here's the data so far. I should have taken some commercial match ammo I had too, but didn't think about it. String 1 - Commercial reload ammo Avg 2911 Spread 25 Std Dev 10 String 2 Nosler Ballistic Avg 2734 Spread 29 Std Dev 17 String 3 Berry's Avg 2689 Spread 54 Std Dev 19 Per Hodgdon's site, I should be about 3,040 given 25.0gr powder BL-C(2).
