I didn't even have to yell at him or get upset with him once!
We first sighted in his new scope with 240gr XTPs in the black MMP sabots with 100gr Blackhorn209 and once we got it close, we switched to the Thors. After a while we decided to go a head let the barrel cool down for 7-10 minutes in between shots so it was cold.
First 3 shots were our first cool down attempt to see where we needed adjustment. Next 3 in the tight 1 1/8" cluster were his final 3 shots at 100 yards.
