Kvintor Exploding Pellets On Game (see disclaimer)

Put half part of a cup pistol primer on the top of your pellet and it will ignite on soft targets like tomatos or simulare.

The problem with these is the pellet will not ignite on the optimal position inside the media.

It depends at cal ...speed and the charge of the pellet

At low speed or energie,

you dont have a deep penetration in media more massive fleshwound 4 times bigger than the caliber but not deeper than a inch

For rats totaly enough
 
In cup pistol ammo ate smal pieces of papers inside.

Thr are soaked or powdered with a impact sensitive flashpowder combustion or simulate.

Put out in of this papers from the cup with a neadle.

Cut it in half or smaler.

Place it on the top of pellet.

Put a smal amount of superglue on it.

Take care that the paper dont will touch the barrel by firing the pellet.

A halt or quarter piece is absolut enough
 
We use to soak “strike anywhere stick matches” in water just long enough to soften the white tip. Scrape it off. It won’t lite when wet. Pack it on the end of a pellet and let it dry. Makes a good pop. But not really explosive. Use to make them into little spit ball sizes and shoot them out of a straw at walls. Kind of like pop rocks the kids now have. 
 
Toy cup pistol is what i mean beware to take other primers .

In case of toycup pistol primers you need a eyeprotection.

Somethimes when cutting them with a scissor they ignite with a smal flash

Dont play with your health the cup primers are a way to make this flashpellets more sensitive about soft media( potatos apples tomatos water filled bottles etc.)

But all is not worth to harm your eyes

If you do it than safty first otherwise dont do it
