My ongoing .357 Magnum Project.
Background:
I have an old bullet collator on my first progressive, (Hornady Pistol Bullet Feeder, modified to flip bullets, but Hornady bullet feed dies I found are not as reliable as TylerR's 3Dprinted versions.....so after the first print and experience with .45, I also printed .40 and his newest .38/357 and found them to work just as well. So I'm snug and smug there.
So I decided to load some .357 Magnum (haven't for a while). But I like to deprime and wet tumble first these days.....after all I have and love my little Lee APP that's capable of making short work of that sort of thing.
Coincidentally, I've printed Tyler's ever so cool quick caliber change for the APP, and needed to print a .357 adapter for it. But the one He has on the list of adapters doesn't work as well as I wanted. Tyler doesn't load .357 so I doubt he tested that one, since the top hole in the adapter is small only allowing the case to drop in, but not made for tubing or other things above it, so obviously it's a prototype, not quite finished.
And....I like my adapters to be cut out tight around the case and the adapter as long as it can be to prevent push outs of the next case in line.
So I modified this prototype .357 adapter in DesignSpark, to make it longer and with a bottom cutout required by that longer body making it suspended only a couple of mm above the medium high shuttle slide.
Here's two pictures:

Printed it out this morning and found the upper hole diameter problem, and one more minor problem....I just assumed Tyler had the adapter diameter the same as all the other adapters....not so lucky....that's what you get when you pick a caliber he doesn't load!;) It wasn't a problem I couldn't fix with 30 minutes of sanding with 320, 500, 1500 grit sandpaper....but we will get it fixed before others print one.
UpDate! Turns out the barrel diameter WAS the same as all others.....16.4mm O.S. diameter! So.....it was the print. I had changed filament to a bright red and didn't change the 220C temp.....and at .12mm high it obviously squishes wider......We have so many variables that can bite you in this 3DP technology.....it was not Tyler's fault....he can't predict changing filament and what that does. The 220C temp was only necessary for the Green I was using when I made my most successful anti stringing settings yet. So I need to reduce the temp....to what is guesswork.:veryconfu
I chose the easy way on top of the adapter....just drilled the hole to 1/2" diameter, 1/2" deep, and stuck 1/2" tubing in....easy peasy.
So how well does it deprime .357? You can be the judge of that......
