I Managed to get to the range for a bit after work to test some ammo at 100m. I only tested those that grouped less than 0.75" on average at 50m. I was thrilled to see four kinds of ammo average JUST under MOA at 100m - Eley Sport, Eley Contact, Lapua Midas+, Lapua Center-X. There were some sub MOA groups from others (notably CCI SV), but the average was a bit over. Best group of the day went to Eley Sport at 0.7", best average went to Lapua Midas+ at 0.97", and most consistent groups came from Eley Contact. At 100m (which is a bit more than 100 yards), 1MOA is about 1.15", and the 4 best performing cartridges all averaged between 0.97-1.05 inches. It was a bit breezy and it's possible that I could do better on a perfectly calm day, but I don't think the difference would be big.
I was surprised to see SK Rifle Match and SK Flatnose Basic get a lot of vertical dispersion at 100m. They both grouped really tightly at 50. My chronograph battery was dead, but I suspect there was a lot of muzzle velocity variation.
The rifle performed pretty well. I still had a failure about 3% of the time, but it's breaking in nicely. I've narrowed the failures down to 2 potential issues: the extra friction from that ejector that is perhaps still not finished wearing in against the bolt, and the fact that I'm using the regular spring with standard velocity ammo. I might order a lighter spring and see if that gets it running 100%.
