Case Dimensions for the Original and Armi Sport (Chiappa) 56-50 Cases

If you have a reproduction Spencer from Armi Sport (Chiappa) in 56-50, you know already that cases for the original Spencer in 56-50 are different than the ones for the Armi Sport.  

Starline makes some fine brass for the Armi Sport, but its been mighty rare for the last year.  A lot of Armi Sport Spencer shooters I know make their own brass from other cartridges, so I thought I'd post diagrams for the original 56-50 and Armi Sport 56-50 for those of you that might want to try forming your own brass from other cartridges.

The original 56-50 has the following dimensions:
The Armi Sport 56-50 has the following dimensions:
As you can see from the diagrams the Armi Sport 56-50 is a touch smaller at the base and rim then the original 56-50.

I have formed brass from 8mm Lebel brass and 32 gauge brass with good results. I'll be posting instructions on how I form Armi Sport 56-50 from both the these cases in a series of future posts so stay tuned!
