I tried some more pellet out of my 300s and Hard as I tried nothing would shoot with the JSB and AirArms pellets. I show two cards with 12 groups in all . But I actually shot 18 groups , but the last card looked like someone shot them while on horseback !! I know there are guys having good luck with H&N pellets . But hey refuse to shoot for me in a FWB . I didn't bother shooting some of the known crummy pellets , just tried to stick with known quality stuff. Hope you enjoy the video .
