Was fortunate to be asked back out to Dead Zero Shooting Range by a good friend and his wife yesterday. Took the WinMag and some handloads that I had worked up with the 220 Nosler Custom Competition bullets over 68.5 gr of RL22. After a couple of over MOA groups at 600 yds, I regrouped, so to speak, and settled down, adjusted the parallax better, and tightened up to shoot a better group finally. Not as good as I had hoped, since I had the great .270" group at 100 yds, but did manage to get a 3.68" 3 shot group at 600 yds, .585 MOA if my calculations are correct. I've got to get a better more stable shooting platform under me I believe, more bags likely. I had to raise my rear bag up to level with a couple of factory ammo boxes, and that made for a less than adequate rest. The 800 yd electronic targets were offline so I found my dial up at 800 by shooting the steel targets. 12 MOA dial up at 600 and 19 MOA dial up at 800. Then, at the nudging from the rangemaster, I shot the small 8" round disc at the 800 yd distance, 1 hit out of 2 shots, close but no cigar on the miss. All in all a good learning experience for sure. Also, heard a funny new catch phrase from one of the shooters that was dialing in his rig. "That's minute of looter all day long".
