Description
Rocky Mountain ThunderCast (RMT) bullets are cast from a lead/tin/antimony allow with a brinell hardness of 18. The hardness of these bullets has been optimized for accuracy while still resisting leading in the barrel. Our special non-sticky lube is Alox free and has a melting point of 165 degrees Fahrenheit, so it works well even in warmer climates.
If you are looking for a very affordable and accurate bullet then ThunderCast bullets are made just for you!

The batch I got was slightly oversize, running from .358 to .360. You’ll need a sizing die for these unless your barrel is oversize.
