Thanks guys. I sighted the rifle in at 50yds because thats about the farthest shot I will ever get. Iwanted to check it at 100yds just in case.

I plan on trying several different sabots to see which will give me the best groups. So far I have bought some crush ribs, hph 24, and 3-petal EZs. Should I shoot 3 or 5 shot groups to do the comparison? Also, how long should I let the barrel cool between groups.
I like 5 since it shows a better pattern, and if all 5 are grouped, you know your gold. How long to barrel to cool, for best accuracy it should be cool or warm but not hot. Last weekend I used a battery operated tire pump with a needle on it that inflates balls and put that down the barrel for a couple of minutes. I shot a 3" group at 200 yards, which was excellent for me, since I had never shot that far before with any of my MLer. Cool barrel is critical to "bench shooters", meat hunters "it can't be too warm", why? Makes the sabot soft, then you get "blow by" and loose accuracy.
