Sadly, it appears the rebirth of the Auto Mag is on indefinite hold. I too was excited by the news, but, wisely it appears, refrained from sending them any money. No news about it in over a year.
The original ammo was from CDM – Remington’s Mexican affiliate. The stuff was loaded way too light to function. Complete ejection was rare and it jammed every shot. AutoMags require pretty hot loads to function correctly. Mating surfaces also require a good polish which was not done at the factory.
The polish part, yes. The ammo part, depends on the gun. The CDM stuff is only "light" for some guns. Other guns run it ok (and even "ok" is tempermental). I clocked some of it in 1983, it ran approx. 1300fps from my 8inch. Not exactly cat sneeze loads, if not the 1600fps claimed.
Original handload data is smoking hot. When they claimed they got a 240gr @ 1600fps from a 6.5" gun, they got it. Sadly, these loads are hard on the guns. They do like to run on the warm side, but at top levels, some parts are not very ...durable.
