Casey,
All I shoot is BP in 44-40 & .38 's. I cast the snakebite large lube groove bullets for the .38, a must for the rifle. Not so critical when shooting revolvers. You can get by with a variety of bullets in the revolvers without losing accuracy using BP. Rifle has to have that extra BP lube to keep accuracy and avoid filling the rifling with crusty fouling. I'll toss in some of the snakebite bullets when I mail you your dies.
