I did a little testing with some pellets today for my .22 Leshiy, basically all JSBs... 13.43gr, 14.35gr, 15.89gr, 18.13gr and some HADES 15.89gr. Best results for me were the 14.35, 18.13 and the hades 15.89. These were all shot at 40yrds off a bag rest 3) 15.89 hades, 3) 14.35 and about 7 or 8) 18.13... The 13s and 16s were a bit scattered. there was a little wind today 5 to 10mph and those hades although I only shot a few shot well.
