Make reagent-infused bullets 'leak' the reagent.

[SL the Pyro]

Bullets actually already work this way, it's just not... consistent. Sometimes the bullets won't always inject their chemicals, and some chemicals don't inject at all. It's more than likely a bug.

It seems that bullets treat the reagent as if it was applied to the skin, and thus the reagent can be blocked via protection (someone wearing a gas-mask isn't afflicted by a sarin-infused bullet). Where as if the bullet is inside your body, it should be applied as if it were injected.

Yeah, that doesn't sound right at all. You'd logically think that chemical bullets would function like the Syringe Gun traitor item... I just worry that doing this would make the Syringe Gun obsolete, since a Silenced .22 Revolver would be superior in literally every way if it were filled with chemical bullets.
