Hey Stanley, did you do any mods to your Storm XT?
Just curious, I bought one and fired it off without moding it and ended up with a bent main spring and a cooked piston seal since it detonated a few too many times on the excess oil that was in the compression chamber. Since then, Crosman sent me replacement parts (seal and main spring) for free. I fixed it, tuned it and put on a GRT III trigger and now it shoots smoothly at 935fps with CPH's consistently and quietly. I have not yet checked it for accuracy, been on the road a lot. As I said, just curious.
