RE: My first missfire....what could it be?
Buy a nipple pic.Mostly used for nipples using the #11 caps but I use a pic everytime I clean breech plug in my inlines.I have 2 pics,keep one in my belly pac and one in my smoke pole bag.One of those nice to have items that could save a hunt.
BUT - could be what already been said - your caps/and or powder.
