This is the trick,replace all the o-rings and pack them away..They will be working and last forever..Im only going to use them in pump only play from now on. I tend to shoot about 150 shots per round tring to keep up with the semis and maybe 50 shots in pump only play...im getting a 500 or better shot avarage before rolling an o-ring now with my Thumpers an i think that will improve once i get some 90d o-rings instead od the 60 and 70d im useing now...
