I once had a couple bags of Activ wads - straight walled hull think Federal wads will work. Had a fellow in Utah who would buy all my once shot hulls and boxes.
I guess most of them will go down range - I bought a case of 20 gauge Activs a few years ago before the ammo crunch for $30.00 - keeping a couple of each to go with my ammo collection. Thanks!
whats funny is I remember when they came out....and now people call it vintage ammo. heck what does that make me? lol. when I worked at NAS oceana navy s/t range, I use to pick up those hulls on 7 ranges weekly. it would fill a pickup bed. management would then sell those once fired hulls for 5.00 an empty clay box full. time marches on.
I remember buying those back in the mid 80's for $20.00 a case (500) sold them at our local club. I thought they were great shells. You could re-load them with Federal recipes several times. I loved them for handicap shooting. The 3 dram 7-1/2 were fast & soft shooting.
I still have a few boxes, and a drum full of once fired empties. I have been loading them for bunker shooting.
I do remember semi shooters complained about weak rims causing fail to extract issues when they borrowed the club guns (beretta 302's.) but o&u's...no issues.
