Hi guys quick question to the gallery, the storage of complete black powder shotgun cartridges,do they have to be kept in a wooden box like the loose powder ? this came up as a question I was asked and to be honest I’m not sure my "feeling" is no but then 100 shells holds a good bit of powder albeit in separate holders, contain that in a small metal ammo box and it could get lively just for the record mine are in a plastic pelly case with a padlock on, in a wooden cupboard
