Hi, I'm fairly new to paintball and my first gun is the Azodin Blitz. The first time I took it out, the local paintball field gave me Karnage Tear to shoot. My gun wouldn't shoot the paint and kept breaking the ball inside the chamber. The field then told me to give Karnage Bite a try. These paintballs worked for me. This past weekend, I went out to a different local paintball field and they gave use Draxxus Basic Training to use. My gun would fire the paintballs maybe 4-5 times and then break a ball. I'm going out again this weekend and was just wondering if there's anything I should double check first before bringing it out. I took apart the gun, cleaned the barrel, chamber, and striker and relubed the o-ring on the striker. Any advice?
