Does anyone know of a (preferably affordable) way of putting a cannelure on a bottleneck case neck, specifically the .30-40 Krag? I've had success with reduced loads in .30 calibers (from .30-30 up to .30-06) using a tiny bit of Unique and a single 00 buckshot. This is a load containing TWO lead buckshot instead of the single.
I've seen the fancy machines from Corbin and similar places but I only want to make a few cases to experiment with, I don't need to turn out 500 pieces an hour.
