Intriguing, and I don't think it's exactly a new idea. Carefully made too...I greatly magnified the image to find the holes are each externally coned AND they are directionally angled towards fore and aft, seemingly to ignite both front and rear of the powder charge simultaneously.
Would like to see a scientific comparison of this idea to the traditional single hole performance regarding such things as breech pressure, muzzle pressure, terminal muzzle velocity, etc.

Never seen that myself. And it probably doesn't make any difference in any practical use. But if one hole ever gets plugged, hey you still got another that might not be?

I'd be glad to have it, it's a neat little unique detail. Just because it's different doesn't mean anyone has to claim it's revolutionary.

It would be worth it to me just to watch the crusty fellows argue over it LOL

I kinda like it. It looks like it could easily pick up the flash even if the charge shifted in the wide pan. Can't see as it would make it worse.

Think you'll find it works better if you fit two flints.

A properly placed touch hole makes it so it doesn't make any difference where the powder is in the pan.

Looks like a half-assed idea to me.

Probably started as a mistake

My mom says the same about me.

Well, we’re blessed to have you here

Cross drilled for performance.

Drilled by a cross eyed gunsmith.

It's a pressure relief measure for when you load it with 4f

I've tried it. No difference that I could tell. Just another hole to pick. Moved on!

 

[Sparkitoff]

Like a disc set striker, the two holes make it easily removable with the right tool. I think that is a plus....

There’s a LOT wrong with that statement!

Best approach, and the right one!!! Particularly if it’s done before opining!!

I was thinking dual quads.....

Fool injection!

Miss drilled the first time?
