I found 2 posts on THR warning about the danger of accidental detonation of toy caps during capping due to their extreme sensitivity.
It happened to 2 people when each of their guns fired by accident.
They did not specify exactly which type of toy caps were being used but I'm pretty sure that they were using plastic toy caps.
But please please please be careful using any kind of toy caps in place of percussion caps since both paper and plastic toy caps are made from the same impact sensitive material.
I wish that I could retract my previous posts in this thread about using plastic toy caps. But since I can't, I can only issue this warning.
Here's the 2 posts:

I was using toy caps for quite a while with my Uberti 1851 Navy until a cap went off as I was putting it on the nipple,the ball shot out the side of the gun hit the frame and shaved a slab off. I don't know where the ball went but I sustained a minor injury to my thumb. Good thing it was pointed downrange or someone could have been hurt. Up to that point the toy caps were working great as they don't jam up the gun like the CCI #11's. Anyway the toy caps go off a lot easier that metal ones and could lead to injury.

Just an FYI guys, do NOT use toy caps in your percussion guns. Although they are cheap and plentiful they are so dang easy to set off it's scary. The sensitivity is many times more than just a percussion cap, it's very dangerous.
I once had my NAA companion go off from using toy caps as the primers, I was putting the cylinder in (I was in my room, going out to the shop to shoot) and I had three chambers discharge due to the gun being loaded with toy caps. It scared my mom pretty bad, it made me jump. I'm a jumpy guy, kinda paranoid sometimes. But stuff exploding is one of those things that makes me cringe. Using toy caps to ignite blackpowder is a dreadful habit. Don't do it!
Also, an SASS member permanently damaged his thumb in 1986 when a regular percussion cap detonated by thumb pressure during capping and the gun fired out of battery.
It was a very rare situation and there's only been a few documented cases found. But this is one of them.
Use a push stick when capping especially if using home made or toy caps and always keep the gun pointed in a safe direction during capping in case the gun fires out of battery.
