Got my bolt turned into a custom swage die but???

[Swagerman]

I had this custom made swaging die made up by an area machinest that has always been pretty good in the past...but he didn't come through this last time.

The special size swaging die was supposed to be .433 diameter with 3 rising stems. It turned out to be .437, which is not reloadable unless I run it through a special sizing die.

Machinest says he can't make a hole that size in the bolt as the through hole is too long. If he tries to ream it out the tool bit will wobble and go oversize.

So, I got me a .437 diameter swaging die that isn't doing me any good.

Going to get back with the guy after thanksgiving and see if he can do something
about it.


I wanted this .433 dia. swaging die to be able to bump-up smaller .44 caliber cast bullets to that size.

What's the difference between cutting a .433 hole or a .437 hole? I see that 7/16 is .4375, and that 27/64 is .4218. It looks like your die was made with a -.001 7/16 reamer; this would reduce machine time compared to boring a 27/64 hole and then having to use a boring bar to bring it up to .433. And then you would have the extra polishing time...of course, one could have a custom .433 reamer made, but that would kinda defeat the whole purpose of keeping it local,wouldn't it? Not to mention expensive...

Seems to me that when you make a hole that you either drill it or bore it undersized, then ream it another .010" to .020" clean up the surface, then you lap or polish it to finish and size. Sounds like someone used a quite different process than this. I've seen reamers prduce six sided holes from too much speed/feed, but I've never seen one wobble (probly too fast there too?). Get him a .431 or .432" chucking reamer. Depending on how much he wants to polish out. You can take .010" out with a reamer that large.

You could always swage 'em up to .437", then run 'em through a .433" sizer.

[Swagerman]

Yes indeed, I can resize them through my .432 sizer die that a friend on the board opened up for me.

But prefer running bullets through one pass to get the proper size when bumping up smaller diameter .44 caliber bullets to the .433 size.

Jim,
Check with Enco or your favorite tool house for an 11mm reamer.
It will be .433071"

...............How long is the hole?

The through hole is 2-1/2 inch to reach the upper die stem stop bolt.

There is no local lathe tool store source up here in these boondocks, everything would have to be mail order.

I've always had the utmost confidence in the machinist, he has done work for major businesses that is a lot more complicated than my little swaging die. So this is a real surprise he came up with this oversize swaging hole of .437.

I was doing better when I use a Lee 30-30 seating die and made my own rising ejector stems for it...that one came out to .436 diameter.

Don't want to go over .433 as it will not reload and chamber if any bigger. In fact may change horses and just go .432 or .4325.

In case the local machinist doesn't want to go any further with this project to make it right, is anyone out there who can take on making me a swaging die body that will handle the .4325 diameter...I've already got 3 ejector stems made that are .437 but should be easy to take down a tad to fit the required diameters.

.............Swagerman, that's a pretty long hole of that ID. I routinely bore holes from .265" OD to whatever a Lyman lube die will take, and that's 1.60" give or take. I use solid carbide boring bars that take inserts. Not alloy steel bars with soldered carbide pieces. These are about as rigid as you can get.

The maker is Circle C and they suggest no more then a 10X stickout using very light DOC's and slow feeds on max distance holes. The 4 bars I have are 3/16", 1/4", 3/8" and 1/2" OD. The 2 smaller bars are 4" long while the larger 2 are 6" long. I could use the 3/8" bar to make that operation. It would probably take 3 round trips (in and out) to bring it down to the last, due to spring, leaving a thousandth for polishing.
