I've just picked up an HW110 (PCP) and entered in a local air benchrest league, so thought I had better get some pellet testing done. I have about 20 different types of good quality pellets to try, here's the first 7. These are all 5 shot groups, shot at 25 yards from a bench but no rear bags (Comp rules). A few "fouling" shots in the sighter with each change of pellet. This first round of testing will be used to eliminate the "no hope" pellets, then, when down to a few hopeful ones I will try weight sorting and different sizing/lubing.
