Buffalo Bore loads their ammunition up to maximum SAAMI specifications, which delivers devastating performance on a wide range of game. Please note that this ammunition is not intended for older guns. It is made for modern firearms only, as some of the ammunition could damage older and weaker firearms. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases. One virtue of the modest velocity generated by the 9.3X62 is that you do NOT need a "premium"/bonded/monolithic/partitioned bullet. Good old cup & core technology works wonderfully on large animals at these velocities.
