   Quality hand-cast bullets for handloaders: competitive and recreational shooters

Scroll down to see our selection of 50 Caliber Big Bore Rifle Bullets

For best results, your cast bullet selection (bullet style, alloy, lube type, GC or plain base) should be matched with your intended application (velocity, type of firearm, powder type, target shooting or hunting, etc.).

No one can tell you which bullet your particular gun will like, not even us. You'll have to try some different ones and experiment. But to get you started in the right direction, we've provided some general rules on how to select a big bore rifle bullet on the Big Bore Bullets page.
