As far as I'm aware it was strictly a pistol round and the only pistol I recall is the Wildey, same as Clint used in one movie, maybe "The Dead Pool".
It was, as you say, a cut-down .308 case.
It was actually made be Auto Mag Corp. The Wildey, was used in Death Wish, with Charles Bronson..
Someone watched Beverly Hills Cop 2 again.
I bet it would be nice in a little semi or handy little carbine ala Ruger 77/44. No rim to foul the feeding...marvelous.
A very short (barley legal) carbine that accepts pistol magazines (so you could have 10 round magazines) would be very cool.
