In the middle 1980s I had a job at an Indoor range as an instructor. We also had a gun shop on site.I remember all the different weapons I got to shoot.We had dealers bring in everything from full auto M-60s to suppressed Mac10s .While going through my reloading supplies I came across these Activ 12 gauge shotgun shells. They are no longer made anymore I even found the loading data book for them.
Just thought I would share some pics to those who have never seen these.I also remember having some indoor cartridges that were primer powered and all you needed to do was push the flat plastic bullet in the case add a primer and shoot.No reloading press needed.
