Strange thing happened with me and my Lynx today. I had the lynx set up to shoot 900 fps with JSB 15.9's. Today I poped out the chronograph after a few days of not using it and strangely it was shooting in the upper 930's with the same pellet. I also tried to replicate the 1050 high fps number that I was able to get in earlier testing and was unable to. I also tried to tuen the power adjustment screw fully CCW and I got a minimum velocity of about 790 with 15.9's. This seems a little strange and it makes me wonder if i'm adjusting it wrong?
The JSB pellets and Preds grouped the best. Either could be chosen pellet. The 18.1 and 15.9 had similar POI. The rifle was sited in with JSB 18.1. The Preds POI was slightly higher.
