I just recently bought a Core Sharc off the internet, it pretty good. i recently made an investment and bought a 16 in JT boomstick barrel GG rite? thats wut i thought when i got on the field i started shooting pretty good till about the 5th or 6th game when my balls started coming out real wild , i said whoa maybe im shooting to hot so i lowered the CO2 pressure and still i was shooting wild as hell. i couldnt shoot anything unless i was no more than 10 feet away BG! wut is wrong ? i cleaned the barrel it was all dirty and i cleaned the front of the bolt but still i was shooting not as accurate as my barrel should be shooting. could it be an o ring? i changed that before i left but still i was left wonderign if my gun is messed? sometimes i wish i had my spyder xtra back... basically can u help me wut was i better off with my Spyder xtra ot the core sharc? and what exactly is going on with my gun? and what can i do to fix it? thx for ur help i appreciate it a million times.
