Get the book by spence wolf. The bores run big on these but a 500 gr bullet will bump ut with black powder. Im happy with the 400 gr Lee hollow base bullet which expands to fill the bore. I think mine sluged .462
Thank you. I will do such.
I have a carbine and on Spence's advice have run the lee 405 Hollowbase cast from 20-1 alloy and shot many a Cast Bullet Silhouette match with them
