Thread: Ideas for an unconventional crimping system

I have recently started reloading for a stunning wee antique rifle in 380 rook
This uses a 38spl case trimmed to 22mm
Also uses a heeled bullet (the same as what a 22lr uses) just a .374 125gn version (think of it as a scaled up 22lr)
The bullet requires crimping for reliable storage and transport

The issue is with a healed bullet the actual projetile is the same diameter as the outside of the case (a conventional round the projectile is the size as the inside of the case)

This means a conventional crimp die won’t work as it will hit the projectile before it gets near the case mouth

A lee collet die might work but the issue is they don’t make the collet crimp die in any calibre close enough to use as is or infact modify a die from

So im looking for suggestions on a way to put a light to medium crimp on these rounds remember that the projectile must be free to pass through till it reaches the case mouth then close to crimp

I did think of a terminal crimping tool but this would be very tedious lol

Any ideas?
