CP, I don't recall where I read this but another issue with plastic bagies is when a misfire occurs, water may not reach the charge to destroy it. I even recall a particullar case where flour was used as the wad and the charge was also wrapped in a baggie, then alluminum and placed backwards down the bore. The quill set the flour smoldering for a loooooooong time and no one was about to try dumping water down the bore untill it went out, and finally when the charge was pulled (10 hours later) the powder in the baggie was still dry as a bone! BOTTOM LINE IS THESE ARE NOT TOYS, AND THERE IS GREAT RISK IN OUR HOBBY, USE COMMON SENSE AND BE VERY CAREFUL! This is artillery, there is NO surefire way of elliminating the risk factor. cb
