My gunsmith gave me six plastic syringes with long needles and told me that the next time anyone had a misfire to insert the needle into the flash channel and squirt water directly into the breach before doing anything else. Sounds like a good idea to me.
Not a bad idea. But if you want to have something handy for doing that - and something very compact in your shooting gear - those little tubes of eye wash with the twist off top made by "Refresh" would work quite nicely. The tapered spout would fit in either a flash channel or nipple. I have a dry eye problem and usually have one around.
