A while back, I ran a group buy for .32 NAA reloading dies.

Now, the insanity comes full circle, as I am soon to be the proud owner of a .25 NAA Guardian.

To compound the madness, I am also thinking of contacting Lee Precision about a run of .25 NAA dies.

Would anyone be interested in this?

Greetings Bowfin,

Were you able to organize a group to order the dies from Lee? I am interested. By the way, being new to reloading (and the Shooters Formum), can the .32 ACP brass be necked-down to the .32 NAA or must I buy formed shell casings? Thanks.

.25 NAA does not have a semi-rimmed case, .32 ACP does. The SAAMI chamber drawing doesn't account for the rim. If you don't see a cut out for that idiotic semi-rim of the .32 ACP, on your gun, don't just neck down the .32 ACP brass.

Thank you K.O. I am ordering a barrel for my Beretta Model 1935 in .25 NAA. Do you know of a source for brass other than the manufacturer?

I did find a company that has .25 NAA dies in stock:

Caliber List : CH4D

So rather than trying to reinvent the wheel, I would buy from these guys.

I do not. Sadly, I think even Corbon and NAA will have dropped this round in ten or so years. It's a neat concept, but ultimately impractical for defense. I would love to see someone (perhaps even myself when my gunsmithing career properly starts) make a pair of 4" or even 6" barreled pistols in .25 NAA and .32 NAA. Aledgedly, both rounds gain something like 200 fps in 4" barrels, compared to the 2" barrels the Guardians are given.

Wouldn't one just neck down the .32 ACP case and trim?

The rim is too wide, then. Unless your chamber is cut for a rim that doesn't exist in the SAAMI spec, your cases wouldn't go fully into battery.

Or are you suggesting putting the cases into a lathe and cutting the rim down?

Would cutting the rim down be an option if it doesn't present a safety hazard or compromise cycling?
