Presume you are referring to 12 gauge. All Americans had a black solid plastic base wad. I never heard of them shooting out, but that was pre-internet era and rumors and myths didn't spread a fast or far then.
The generation of Remington target shells just before the All American had a white base wad. Actually it was a white plastic disk covering a traditional fiber base wad. I heard one story of them shooting out.
Base wad was very high. Not too bad of a handicap with a MEC 600 Jr, but loading on a MEC progressive generally means the primer/powder drop station has to be readjusted.
Wads will be hard to find. The red AA wad or clone will work if you can find some of those.
Red Dot was 17.0 grains for 1150 fps, 18.0 grains for 1200 fps.
