First shot at 600 yards was 1.25" high and 3.5" right. Now THAT'S impressive ... not the shooting ... the fact that the comeups were on the money. I've only shot this .300 Win Mag at 100 yards so using chronograph data and Hornady's ballistic calculator, I printed out a cheat sheet and headed off to my first match yesterday. Prior to this match, I'd never shot at anything beyond 200m .. well, not at targets that can be scored. I had zeroed the rifle for 200 yards at our 100 yard range using a -1.5" point of aim and Hornady's 208gr A-MAX with 71.7gr of Reloder 22. At the match, the first sighter at 200 yards was a 10 and the second sighter was an X. At 300 yards, Hornady wanted a 2.2MOA comeup so that's what I dialed in. First sighter was a 9 and the second sighter was a 10. At 600 yards, Hornady wanted a 10.3MOA comeup, so once again that's what I dialed in. First sighter was a 9 and the second sighter was a 10. At 600 yards with a 5mph wind, the correction was 1.5MOA. I had 1.0MOA dialed in for the first shot but added 0.5MOA and decided to leave it there since the wind was variable and based on my "extensive" experience of ZERO, I wanted to keep it simple. Anyway, I'm just thrilled at the accuracy of the comeups and the fact that they were basically dead nuts on. That was a BIG surprise to me.
I figured out that I REALLY need sunshades on my Mark 4 scopes. The sun was creating some big glare-related problems for me in the morning.
