Wish I could help you out with ammo info but I just wonder if the round is a 'proprietary' round. If so, being able to get the ammo with the rifle sure makes life a lot simpler. Sixty rounds will not last you a life time of busting cinder blocks all to hell but then you have to pay the fiddler to dance ! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
