While in the process of building my presentations for HFS and BP classes I went looking for cut-aways and animations to use and came across these. I did a quick search here and didn't turn up anything so I thought I'd share for those people who do use PPT as a training aid. It is specifically designed for hunter education but the action animations and the ammunition animations are in my opinion a perfect supplement to the hands on a student gets and it's a lot cheaper ($99) than buying or making cut-aways of guns.
