I've got a selection of .32 auto (old WRA ammo) & .32 Short Colt brass I'll mic some tonight

I can tell you that .32 acp does NOT chamber in a .32 RF, if that's what you're looking at (.32 ACP is too large in diameter), I thought it may have been an option (for use in the .27 cal Hilti conversion) before I found .32 Short Colt brass.

Short speaking 320 and .32 short colt differ in two ways thinner rim and 317 bullet on 320
Bullet is .312 on short colt.
.32acp different breed alltogether. More similar to .32s&w short, long.

Would a 320 bulldog manufactured before 1898 fall under Canadian antique status then?

What do you guys use for brass and bullets? I am having no luck on finding info and would like to know before my purchase what to use. Thanks for the replies BTW guys. Cheers. Luc

.320 brass is mad by Starline , while .32 short-colt is made by Winchester (IIRC)....

I checked the Starline brass website and could not find the 320 brass. Am I missing something? Do you guys have a link to load data for it? Keeping in mind im new to reloading. Thanks. Cheers.

Yup the new .32 Short Colt brass I have is Winnie and seems to be the only brand I've located in that caliber (for new manufacture, that is).
