Description
Rocky Mountain ThunderCast (RMT) bullets are cast from a lead/tin/antimony alloy with a brinell hardness of 18. Â The hardness of these bullets has been optimized for accuracy while still resisting leading in the barrel. Â 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 our RMT bullet is made just for you!

Good value for the money, load and shoot nice.
Just got done loading 1000 of them and the only concern I have with them is there’s around 80 out of the 1000 that weighed over 235gr with the heaviest at 243.7gr. The heavier projectiles had thicker bases and a visible melted lip that projected beyond the swaged width and prevented them from being inserted into the cases without filing.
Not a big deal tho, I’m loading low velocity\pressure rounds and the heavier projectiles won’t cause any overpressure problems.
