SO I dont know how many of you have this problem but here goes...I used to ahve a 98 C with x-pansion chamber and a bunch of other mods. Used co2 and I had the gun freeze a few times on me. Is that because the co2 is so cold and I was shooting it to fast? I just bought another 98C (after 2 years of being out of the sport) and my MOD list is growing. I thought about running a differant type of gas on this tippman. I do mostly woods, and was wondering if there are any benfits of running somethnig else?
