I have been loading some big old cast bullets lately in my 45-70. Love shooting that cartridge!
This is a selection of the bullets I have been trying lately.
On the left is Bullet barns 525 hard cast postell. The second from the left is my custom made mold that is an adaptation of the Postell design, but 550 grains when the soft lead is cast. The two bullets in the center are a design I had drawn up to fit my Browning 1885 BPCR chamber. The bullet on the right is a 425 grain bullet I cast that has two crimping grooves so I can use the lower crimp groove and still reach the rifling lands with the short Hornady brass. A handy option! The flat point on this bullet is nasty!
