.32 colt.

I have 300 new Winchester 32 short colt brass… so it sounds like I need a centerfire block

The .32 Short Colt is too short to convert to using a blank unless you use acorn blanks. Then you need add propellant, blackpowder being the safest but messiest to clean up after. 
  If you have a lathe and the capability to use it, you can make the 32L RF cases from 32 S&W Longs but it is a big undertaking. Then you can use nail gun blanks (Level 2) as both primer and propellant.
  The molds are out there;
Accurate Molds 31-090S is a very good one and gives you options for choosing your dimensions and alloy. I don't know what current delivery is.
  Old West Moulds has 32 heel bullet molds also and a crimping die if you so desire.

There was a gentleman who was forming down .32 S&W Long cases to make .32 Long CF and they were great. I've fooled around trying to make them before and wont ever spend that much time again. 
My molds are an NEI Walt made for me many decades ago, and an original Ideal mold for the heeled bullet. Both cast lightweight bullets for slower twist original barrels and shoot well in my Ballard #2.
I used to find a lot of .32 Long Colt ammo at local gun shows cheap, and since my Ballards could shoot CF or RF I bought both cheap. Most for under $10 per 50 then. Some CF didn't go bang due to age, but were fine to reload with. Most of the RF I later sold to a guy as a lump deal. The .32 Long rifles shoot excellent with good bores, and even better with loads of smokeless I worked up.

Phil Way (uscra112) by any chance? I've used his technique to make .32 Colt brass. Once I had the swage die perfected and the protocol for finishing up in my Unimat worked out, the project went fast. I ended up making 100 cases. Then, on another forum, a pile of .32 Colt brass turned up which turned out to have been made by Phil before he passed. I smiled when I saw his name on the container. Certainly was a fun project. A heeled 85gr. bullet mold from Accurate rounded things out.

It's also a hoot making .32 RF's with acorn blanks. The only .32RF gun I have is a Frank Wesson Pocket Rifle, so it's not like I shoot it much and certainly don't wish to mess with it by converting to centerfire.

I sized the heel of the mold from Accurate to fit my brass with thumb pressure after firing in my chamber, and the major diameter to match the throat of my rifle. Load and shoot at the range.

Good point. I have to do that for use in the Wesson.

Well Curt, then I would be looking at a modifying of original to centerfire.  Or I may say to hell with it and save myself a headache
