Fusil Breech Plug Mod

[EcoGang18]

I bought an Indian Fusil De Chasse that I plan on shooting but first I have to mod the breech plug. The problem is that the end of the breech goes in too far forward in the pan so I have to cut a V groove in the breech plug but I have no idea what type of breech plug this is. Do I drill a hole or cut the groove?

Also you can't persuade me NOT to modify it to workin condition.

Wow. It looks like a bass-akwards try at a patent breech. A good portion of your powder charge is going to be behind the touchhole. You could file a groove in the side, but I imagine you will have ignition problems. Can you fit a new breech that has a flat face, not a hole?

I had to cut a groove in the breechplug of my first and only build, and I do NOT have ignition problems. Ignition is instantaneous.

Here's some photos of a Pedersoli breechplug used on their flintlock musket. The breechplugs are brand new & both plugs are grooved like you are talking about. You can see the plugs need some final filing, but this grooving was commonly done in years past.

I had to groove the face of the plug in my Trade gun. I drilled the vent hole with the plug in so I could see how deeply I had to cut. I used a chain saw file so I got a nice smooth groove that tapered up across the plug face (unlike the ugly mess on those shown above) I also rounded the edges of the groove with a Dremel tool, and polished the plug face (for easier cleaning). Twelve years down the road and no problems with ignition or cleaning.

I too once notched a plug similarly on a Fusil de Chasse, using a ball end mill and that gave me all the curved features needed . Added a little polish and she's been flawless!
