Ok, well let's just say this is just my bad luck or something. I got a few shots off dry firing with this bolt. Worked fine, I was pretty happy. I took it out to a field to shoot a few paintballs but only got about 50 off before it had swelled up. No breaks, no nothing, I was in 100 degree fahrenheit temperatures (30 Celsius) outside in Canada, no clouds in sight, dry as hell out but it still swelled. After that I have had no luck in getting it to come back down into normal size. I'm left with no option but to sand it down. I was forced to play two days with the stock bolt which did not make me happy.
Maybe I was just very unlucky but this is not a bolt I'm holding on to or using unless i can sand it down and keep it as a backup to my Jambolt.
