Wolf was one brand, a little rough on extractors in some weapons, yet any steel used for a case should be much softer that the steel for the firearm.
The 32 was a long time, just for fun, project, a friend has 2 plated revolver, H&R and Iver Johnson, police revolvers from way back when, 32 was enough, probably still is, being here in the Idiot Tube Society everyone thinks they need more and more power like in the movies.
I'm also thinking on a case of 9mm, 124 gr. is about as cheap as 115, probably make the machine run better.
