The cheap surplus ammo is not cheap anymore. It doubled in price last year, although it's come back down a little. The reason the round works so well against soft armor is the bullets are small diameter and steel-jacketed.
I'd like to pull some of the bullets and load them in .30 Carbine, which is a much hotter round, just to see what they'd do from a Blackhawk or Automag III.
Now I need to go check some cheap steel-cased Commie .30 Carbine ammo and see if any has magnetic bullets... If so, that's the way to go.
