Musket nipple question

[mkabe]

Hey guys, that includes gals as well, what purpose is the small hole in the cone of my musket nipple, picture included. I can guess but would prefer to get a right answer from someone who knows.
Thanks

It’s made as a vent. The sparks are supposed to go to the powder rather then the whole flash.
Now the argument can start.

Modern day sales gimmick… never saw one on an original, nor in competition.

I always thought those holes were escape holes.

So the gases could go out the holes instead of driving the hammer backwards after the main charge detonated.

Looking forward to seeing more answers.

While listening to K.M. lose a 12th vote.

That was my thought too. It would relieve some of the back pressure from the main charge.

Thanks, that’s what I figured. I have a replacement TRESO made from AMPCO alloy that doesn’t have the vent.
I’d be interested in hearing the yea’s and nay’s on its value. Guys, argue away…

Also serves to expand the cap so it is not stuck to the nipple after firing.

That's because the 'hole' is a modern patented feature, so not all nipples will have them. The intent of the hole is to release gas from the ignition enough to split a standard percussion cap open for easier removal.
