Greener than a gourd...

[sharps4590]

I am in the process of completing the purchase of a.....pile....of swaging tools and jackets. One thing I have is 1000, 30 cal., 1.08 jackets in four, unopened packages. I have absolutely no use for these. Would anyone be interested in trading for a like quantity of 8mm, .318 jackets for them? Or, is 30 cal. jackets used to swage up to 8mm and I'll need them? As the title says, I'm greener than a gourd abut swaging bullets. I'm certain I'll have a ton of questions as I peruse the sticky's.

Ok....have learned much the last couple days, all of it from the Corbin site. My presses are the ones no longer made and take the "S" dies. Not much info on the old press and operation that I could find but I have figured it out. Everything came loose in a box...kinda like getting a wheelbarrow full of motorcycle parts and building a bike...with no instructions. Evidently I have to make 8mm jackets as Corbin doesn't list any and I couldn't find them anyplace else. Ordered a book from Corbin. As with most things it appears I'll be learning this on my own.

In each swaging step, the jacket gets larger in diameter. You might be able to expand the 30 cal jacket to what you need in the core seating step. It will take some trial and error. The amount of pressure generated is pretty amazing.

Corbins books are very good.

Thank you garands! Most of my 8mm's are .318 so that's .010 more than .308. Does that sound doable to you? I do have 1 or 2 rifles that are .323, does that sound like too much?

And, I'm trying to figure out which presses these are. Now I'm not certain they take "S" dies...I don't believe they do. It looks a lot like the Silver press except that it has what appears to be a reinforcement bar cast into it from where the 7/8 X 14 die screws in and the body where the ram is mounted/operated. It appears the die that screws into the ram is the 5/8 X 24 size though I haven't measured it yet.. If what I "assume" is true it should use "M" dies? I received 3 presses and 4 complete sets of dies for .357, .430, 30 cal. and one I haven't measured yet but from the look of it and the jackets I measured it appears to be 32 cal. The jackets are really short, like the 30 cal. M-1 Carbine half jackets. The dies are still sealed in what I presume to be their original packaging.. The purchase also included a pile of jackets for each.

Edit: Ahh...also received a die that is evidently for drawing 7mm jackets down to .257 and 500 7mm jackets. I'll keep those for my 7 X 64 Brenneke...if I can get dies.

It sounds like you have a Mity Mite press. Yes they use M dies

Does the press look like this?




Also, (from Corbins' website):

-M type dies - special order only
Type -M dies are the same price as -S type, and are a discontinued smaller style made for the early Corbin Mity-Mite horizontal cast frame presses. These are still in service, even after 30 years, and Corbin provides repair parts, tooling and dies for them even today. But the -M dies are not promoted or advertised, since they are made to order (but for standard prices shown for the same kinds in the -S type series, not a custom charge).

The main difference is die body diameter and die length. -M dies and their internal punches are shorter than -S type, and have a smaller diameter body, even though the thread area is still 5/8-24 and will work in the current Corbin presses.

Bob, that is it precisely, thank you. I read previously what you posted from the Corbin site but not being certain on the press, and Corbin's lack of pictures, I wasn't sure.

If they still make the dies for the same price, I can live with that. I'd only want to add 7mm and 8mm some day.

Richard Corbin has a set of 8mm dies check his site also

Thanks contender! Are they for the Mity Mite? I'll try to find them as well.
