I write an outdoor's article for a weekly paper, had a reader contact me for firing a new ,45Cal flintlock rifle.
The smith used a Green Mountain HEXAGONAL bore barrel blank.
This is similiar to the CW Whitford rifle that used a 1-3/8 long hexagon bullet with hollow base.


Is there a formula for determining a bullet length for making a similar bullet for using in this ML?

Lyman and DGW once made a mould for the original Whitford and current replica, so any leads for tracking down information will be great.

I will contact the MLNRA and the NRA dope Bag for additional sources.
