To avoid in future, get a couple of old Activ plastic hulls, punch out primers, replace with BIC mechanical pencil erasers, cut off crimp area and shorten such that they can be easily distinguished from live shotshells, place in chambers, pull triggers, take off forend, open breech, remove, close breach, replace forend, put away. Place expensive snapcaps in case with your turnscrews, jampot, and collected works of A. A. Milne. Lock case. Put away.
