This price is based on 50 bullets. These hollow base bullets weigh a nominal 290 grs and are cast from a soft alloy. They will work in a vareity of bore sizes due to the alloy that is used. They are sized to 0.454″ diameter and are shipped lubed. A soft lube (Alox) is used. These bullets are not meant for high pressure loads but rather for period typical loads. If you are loading for a 476, the hollow base will expand to engage the rifling. However, we expect to soon be adding a heel bullet specific for the 476. Shipping weight is 950 g/50 bullets.
