Hard Core Big Bore.com
Enjoying the sport of hunting and shooting with big bore airguns.
Mark makes cowboy action bullets mostly but has started making them in pure lead for airguns. He has several designs that will work for big bores. The 390 grain Big Lube bullet is the only one I have tried at this point. My DAQ .457 LA (.458) and my Gargoyle (.452) both love them. He only offers them in lots of 250 for around $58.
