I cast up a pile of these bullets today out of pure soft lead. Dip lubed in Gatofeo #1, and run through a Lee .501" push through sizer. Shot out of my Renegade with the Green Mountain bullet barrel on it, I was seeing some mighty tight groups at 100 yards with them loaded over 100 grains of Goex 2F or my own homemade powder. Funny how a 1/2 inch center to center group is one hole if you're shooting a 50 caliber! Anyhow, if you want a good hunting bullet for your 50 these RCBS bullets seem to do the trick.
