That's for Big Bore Boys! I'm not that n never will be. I shoot way to many rounds for that! 1 mile is stretch for 300WM. Maybe build 338 lapua someday. But that's as far as I go. I would rather out shoot everyone at 1000 to 1500 yards. then a few at mile plus. LOL.
My memory may not be correct, but I believe the winner last year was shooting a .375 Lethal Magnum. I did not get there early enough to watch their match (we were preparing for our 50 Cal World Championship Match). I don't follow it because it requires shooting from prone, and I'm unable to shoot from that position. It also cuts me out of the PRS type matches, so I stick with Benchrest, and our matches limit out at 1000 yds.
