It was a really windy day, and I shot 40 Hornady 20gr XTp's, and about 20 Hornady 17 gr VMAX's. The 20gr's grouped under 1 inch mostly at 50 yards. At 100 yards the 20gr's grouped just a tad over an inch with 5 shots. I'll try again and decide on a calm day. It's actually shooting the 20gr's surprisingly well now, and especially on a windy day.
I'm thinking my gun likes the 20 gr's WAY more.
