    Two Attempts

    I whipped up two potential designs just now. No scoring, as that would take a while. I think the resin plastic will shatter well enough without it.
    For your consideration, two pictures. One is a plain cup, the other has a lip on the top to help capture the shot and in theory make it easier to close without fussing with over shot cards and so on.
    I can run a print, 35Whelen, if you're interested.

    If you want my opinion, I feel the top design will be much easier to put the shot in. Also, if it were me, I would make the outside diameter of the capsules .311 or .312 diameter. You have an excellent idea in this project and I am very interested in the results.

    I think the top one will definitely be easier to load, but the second one may be easier to seal. Tomayto, tomahtoe.

    Thanks Bulldogger. I like the top design very much.

    Without some sort of something to close the capsule and keep the shot therein, seems to me a fella could charge the case, seat an over-powder wad or gas check, fill the capsule with shot, invert the case and insert the capsule, hand seating it and the shot load against the over-powder wad, then give it some sort of light crimp.

    Length of capsule- That's a tough one, but I'd think that in order to get the most out of the diminutive .32 Long case the capsule would need to protrude from the case at the very least as much as a bullet (.36") preferably more. I'm thinking a minimum 1" long capsule would work, but I'll take some measurements when I get home.

    Diameter of capsule- Since it appears the capsule would need to be hand seated, I'm thinking it would need to be a tad smaller than the mouth of a case after it has been sized. .306" or maybe .307". Again, some measurements are in order.

    By "print" I assume you mean a doc with measurements?

    Thanks again for doing this.

    Just for reference, this is why I need shotloads. I killed it last week behind my chicken house where the grandkids play.

    I made shot shells for a 30-30 Contender pistol once. Use soda straws from McDonalds. Used a clothes iron adjusted to a suitable temperature to close the ends. They were slightly small but Scotch tape fixed it. Worked fine for close encounters.

    The 3-D capsules would probably be much better.

    That will be a great tool.
    My pet project is running OCR software on "Handloader" magazine. That's going slow due to the ads varying so much.

    By print I mean I don't mind running a batch to send you, unless you already have a resin printer in which case I can email the STL file to print on your own.

    I think the press fit into an over powder wad would work.

    I can tweak the design once you provide certain measurements for the capsule.

    I don't have a 3D printer, but I appreciate your offer and will be glad to pay you for your efforts.

    Just thanking but for S&w long or hr mag can’t you just use a nagant case cut just short of cylinder leingth or use a 327 mag case cut to cylinder length ? Fill with powder add your card wad add shot then top it off with another card wad crimped in place and or glued? Don’t know never tried it. But That would be the easy Way to do it. Would it work? Just thanking

    My .32 has a bore size of .308, and depth of lands .312.
    I believe you want the shot capsule to ride the bore and not be engraved by the rifling.
    So the shot capsule would be too large if the diameter were .311 or .312.
    I make the capsule to slide thru the bore so it doesn't rotate by getting engraved like a bullet.
    Also, a much lighter charge to shoot the capsule is needed to keep the shot capsule from expanding to engrave rifling.
    It all needs to be balanced to work best.
    Experimentation is the best tool the handloader has.
    Lots of work, yes.
    But worth it when you find the load that works for your firearm.
    A wad to cover the shot will eliminate leading as long as you don't use too heavy a powder charge to cause the capsule to obturate or swell up to engage the rifling in the barrel. A shot capsule will disintegrate and spin in the rifling with a charge that is too heavy, blowing the pattern as the powder can even blow thru the wad and cause the shot to blow out of the capsule before it even makes it out of the barrel.
    A too large in diameter shot capsule causes the same problem.
    Balanced charge and balanced wad diameter and wall thickness of wad.
    It's not gonna be easy, that's why so many reloaders say the heck with it and just put a gas check over the powder, dump in the shot and top off the case with another gas check.
    Leaded bore, donut pattern, and waste of shot, but it works after a fashion and you can keep pulling the trigger till it gets riddled.
    I have made these using gearnasher's method and made shot wads for 38/357,32 and even. 380 and .25 acp shot loads. With no.12 shot, they are better than .22LR shot loads.
    The shot capsule has to fit the bore and the powder charge has to be just right for my pistol.
    The load for my pistol is custom made for my pistol.
    General instructions will work, but it all comes down to a custom load to fit your pistol.
    No one load or one size will work as well for every pistol.
    It's not easy, but just needs some experimentation.
    The easiest is the .45 auto, and it still takes some final fitting to work well.
    The .32 is worth it, but you have to teach yourself as you go along. Give it a try. You can do it like I did.
