I've had 4 boxes (approx 160 rounds) of .43 cal RAM (Real Action Marker) ammo for the shell ejecting pistols and rifles knocking around for years. The last time I looked, they were basically unobtainable in the UK. Both the shells and rubber balls are included.

If you have a RAM pistol or rifle, and you live in the UK, and would like some free ammunition, just PM me your address and they will be winging their way to you within a week, free of charge.
