Been a while since I posted. But I now have 750 rounds down the barrel. She really really likes Sk standard plus! The groups have tightened up significantly. Here’s a 20 shot group at 50, and a 50 shot group at 275. Both shot today. At 275 my first guess was a little off on the wind, but after that they stacked in nicely. I couldn’t be more happy with this setup. I was also lucky, and found a 5000 round box of same lot Sk standard plus, so I’ll be in business for a while.
