* Lead roundball 50 grain or sized LRN 90 grain (Roundball use with .27 caliber Green Ramset as is. If using LRN subtract powder by 0.2 grains.)

Starline makes the brass, and Doubletap (a site sponsor) sells it. Lee makes a 0.310" Round Ball mold, and I've used #0 Buckshot, sized to 0.310"+ (depends on your gun's bore and chamber size).

Any sources for the 32 colt brass?
What about sources for the 50 grain lead round ball?

Hornady Lead Round Ball .32 Caliber .315" Diameter, Product # 6003


Cases can be fabricated from the thinnest walled 0.313" Seamless Hydraulic Tubing, then add a 180 degree flare for the rim.

Think it's feasible? Any input is appreciated.

I don't see a way to seat a primer or hilti cartridge. Any idea for that?

I think Starline may have stopped making 32 colt brass? Hasn't been on their website list for a while.

My 32 Short Colt brass is from Winchester - WSC32SCU. Perhaps Higginsons could get it.

Here's a pic of what it looks like with the 27 Cal Hilti in place (after firing):

You’ll need:


  • 27 Cal Ramset Powder Charge - "Green" has about 2.3 grs of powder, "Brown" has about 1.7 grs
  • Winchester 32 Short Colt Brass. It's a bit shorter than 32 Long Colt (you can make it from 32 Long Colt and 32 S&W)
  • a 0.311-0.314" Round Ball (“0” Buck sized down works well) –will weigh about 48 grs
  • a 17/64" and a 21/64” drill. A lathe is the best way to drill the holes.
To apply this to a larger round like the 38 RF, you have to offset the holes so the the rim of the Ramset is against the edge of the brass. I'd make a jig to hold the brass off centre and use a 17/64" end mill to make the cut. (my next project).
The beauty of this setup is that the Ramset is both the primer and the powder charge, and you don't have to line up the round to align with the firing pin. The powder seems to be like Bullseye in Burn Rate (fast) and for my Remington #4 Rolling Block, "Green" contains a suitably mild charge for a 48 gr Round Ball. Brown 27 Cal charges are very difficult to find, and are required IMO if you go heavier than the 48 gr Round Ball. Firearms not as strong as the #4 would require caution using the Ramset charge - you might want to empty the powder and replace it will blackpowder, or a suitable smokeless charge.
I press the Ramset into place by squeezing it in using a vise - once in place, I do the same with the Round Ball, then put a dab of Alox on it.

Drill a two step hole into the base of the 32 Short Colt Brass - a 17/64" (0.266") all the way through the web, then a shallow 0.328" (21/64" drill), deep enough that the Ramset charge sits flush. Notice how the firing pin nicely strikes the edge of the Ramset.

The thinnest walled 0.313" Seamless Hydraulic Tubing yields an ID of 0.243", bored out with a 17/64" bit would allow seating of a .27 Hilti blank?

I'm just trying to figure out what I missed here.:confused:

Cartridge brass needs to seal on the base or head. The tubing is an open ended flange. How does the hilti cartridge seat in that and seal the case? I dont see it working as is.
 
The 27 cal hilti will seal the base. Same way a primer seals the base of a centerfire. If you saw a colt case setup for a 27cal rimfire it really just looks like a tube with a small rim

Will the flange (rim) be thick enough to accept a countersink? Or is the hilti rim just sitting on top of the tubing rim?
 
Bud I wrecked so much brass trying to get the .32 short colt rim thin enough to support the blank yet not burn through the brass. I lacked the skill gave up, sold the brass and I just use the French made kit with .22 blanks and round lead balls. No accuracy to speak of but fun none the less

Yup thats her. You can probably use a flair tool then anneal it before pounding it out flat to make the rim

I used these in a remington no6 i opened up the chamber a bit so i could use 32 SW brass though. Ill post pics of the brass. Its exactly what your pics look like

Looks like this.

Very cool. I guess using the .22 crimp blanks would be the same idea, but you use actual spend Rim fire cases. These cases would much better it seems? Long ago I helped a buddy make some with a .22 crimp blank..it must have been a Rim fire brass to begin with I believe. This set up seems better components in comparison. Obvi. the .22 crimp wont work right, as per center fire brass. *EDIT I see how this is working now lol. Those Hilti with either home made brass, or .32 S&W brass. Interesting.
