My woverine 209 just came today and i watched the video and read the manual but there is something that is still unclear to me. In order to fire the gun you load it, pull the hammer back, then put the 209 primer (thats in the jacket) onto the nipple, then does the hammer stay pulled back until you fire it? Thats what it seems like to me, but then i wonder what if it got full of snow or something, it wouldn't be able to shut.

Also I was wondering if those jackets that you put the primers in are reusable?
