Ok I had some chances to play a little. I was shooting 91.5 grains of h1000 with the 250 primer and 300 berger. Shot tremendous even at 1827. Then the next day I went back to shoot for some video. And was high with the same conditions as the night before. Then the groups opened up. So I went back to the drawing board. One load stood out in my mind that was 88.5. I decided to test this load along with 89.0 gn
So In the mean time I put together another edge with a shorter barrel. The other one I believe finished at 29+ the brake. I stuck it in a hs precision stock and had a 20 moa rail and a huskemaw that I stuck on it. This gun was not bedded but has a hollad oversize recoil lug in it. It fit very snug.
I also finished a 6.5-284 that I was playing with as well tonight. I will show you a target of it as well. It shows some promise.
What I found tonight was weird both guns shot the exact same groups and same group formation. I was dumbfounded by it. But here is what happened.
I do have to say that the short barrel need a stick of mercury it is light and has alot more recoil.
I did not note but what I have seen before noticed in my records happened again I believe. I had 63 rounds through this gun when the groups changed. I had this happen once before at 55 rounds. So I wonder if the barrel really just broke in. And on this edge I stuck 8 ounces of mercury in it. Was 12.25 pounds before the mercury.
