Percussion Cap Question

[Critter Getter]

Havent given much thought to it in the last 40 years or so of shooting BP guns, but what powder type is inside the percussion caps like CCI? Is it just as corrossive as all black powder is? Greg.

All priming mixtures today are non corrosive.

All priming mixtures today are non corrosive.

And Black Powder isn't corrosive either...

OK.

I guess Brit should have said, the residue from all modern priming mixtures today are not corrosive before or after the cap has detonated. That includes the mixture used in modern percussion caps.

It is a mixture of lead styphnate and barium nitrate.
It's non corrosive but the flame from a cap will heat steel and remove rust protectant or gun oil, leaving the exposed metal subject to rust as any unprotected steel would.

That’s interesting. Then I assume that concoction is more of a modern powder or is that the same cap priming powder used back when percussion system was first invented? Greg

No, it is not the same. Originally, Mercury fulminate was used in caps....https://en.wikipedia.org/wiki/Mercury(II)_fulminate

Correct.

Over the years different concoctions have been tried, all seem to have some drawback or the other.
They can be toxic, self deteriorating, shock sensitive, and corrosive.

Flints on the other hand, are non-toxic, can last for millions of years, are no more corrosive than the powder in the barrel, and can be used to skin a fish with.

Organic flints. That's one way of looking at it.

Free range too.
