Mike, this might interest you.
This Auto Mag is 45 years old believe it or not, made in 1975 by the late Lee Jurras. Lee owned Super Vel Ammunition Company back in the 70's and is credited for developing the modern hollow point pistol ammunition. Lee hunted all over the world and was awarded the Outstanding American Handgunner award. Here is an article written about Lee by John Taffin.

It is chambered for the 357 Auto Mag cartridge which is a rimless 44 Magnum necked down to 357. 158 grain bullets are propelled at close to 2000 fps from the 8 1/2" barrel.
I really like the case, it just screams 1970's. The brace/buttstock dovetails into the pistol grip and is removeable. This SBR is covered under Curio and Relics by the ATF.
Lee designed this for long range pistol hunting and targeted the "Executive Type Hunters".
