This is my heavy for the 38-55 Legendary Frontiersman from "Accurate Molds" Tom does a great job producing excellent molds that drop to your exact specs..
I cast this one heavy at 30:1 alloy and order spec diameter .382 sizing to .380..Gas checked and lubed it weighs 320 grs & is very accurate at a tad under 1400 fps
No pressure issues so far with this load of 5744 and mag primers hoping to bump this up some to 1500 fps if it continues to behave..
L to R 275 & 320 grs
I highly recommend Sage "gators" for either of these bullets.
