Well I made it back out this morning...... What I found was that it is mostly operator error. I shot 5 different loads today, and while I did find one that the gun seemed to like the best (Federal 160Gr Nosler Accubond); I also learned that I am not doing my sequence quite right.
I got a 1.25" group at 200Yds that was about 5 inches Left and 4 inches high, then tried the rest of my options before tring to dial that load in (to make sure nothing was better). After I decided that this would be my best option, I began to adjust to get it right. I was getting fairly inconsistant groups (4-5inch's) at 200 until another shooter asked if I was trying any "cold Barrel" shots....... At this point I had one round of the perfered ammo left and had a group of about 15" at 300Yds with the 3 previous rounds. He told me to run a dry patch through and wait a few minutes then fire that round..... That one hit on the low corner of the bullseye at 300.
Guess my next question should be what do you guys do when sighting in a rifle as far as cleaning, or dry patching, or barrel rest between either shots or groups? I will have more of the same ammo next time out; and will be working on my mechanics with a pellet gun to help the shooter a little.... Any other tips?
