I just want to give a HUGE thanks to Moon, George and the rest of the guys at GA Precision. They took over a build for me that was a long time in the works else where. The gun turned out sweet! As always they turn out nothing but top quality work. This is a lefty for my Dad. It has one of the first designs of the Bighorn action. As always these things are smooth, and you got you love the floating bolt head. This is the third gun with the Bighorn, and if I ever do another build it will have this action.
I know how much everyone loves to see groups. These are the groups from breaking in the barrel. I did the same load as with my GAP 7wsm, and went a little higher and lower on the powder. Did not change the seating depth at all. 64-66 grains of H1000 180vld's. They all shoot good, but 65.5 ended up with the nicest group at 100 yards. Took the gun out to 1000 yards to see how it would do. Dialed up 24 MOA for 1020 yards. Just a guess on the speed . First shot was over the target. It end up taking 22.7 MOA to get on the steel going 2970fps. My Dad was loving it. He was stacking them in there.
So we went back out tonight just to confirm our dope for the cow elk hunt tomorrow. At 1020 yards his first shot was and inch out of the 2 inch black circle. Kill shot. After putting 5 more rounds on the steel we moved to some rocks. He was able to git a second round hit an a 12 inch rock at 1240 yards. I snapped some pictures of the gun just before we left. Hoping to get some good video of the hunt and some more shooting.
Thanks again Moon!
