I'd like to think so, it uses a standard mould that you could hook handles up to for casting by hand.
The only thing that can cause quality issues is when you drop the projectile fro the mould, if you put a cloth down, you have a cushion for it to hit and not dent, but if you have a pile, there is always the possibility of a dent in it as it's still a little soft when it hits another one.
For my pistol rounds, they still shoot better than i can!
