310 muzzel sizer marked 300

[reloaders4you]

I have looked in every book I have and can't find in info on a Lyman 310 muzzel sizer marked 300. Any info would be great!!

I'm going to guess it was for a 300 Savage(?) There are also the various .300 Mags, but I'm not sure that Lyman was making that wide a variety of dies by the time those calibers came into vogue. Of course since it's a neck sizer, you can use it for anything that has the right size neck diameter.

can you post a picture of the die? It could be a RedHead die, I am not sure they had a MR type die as I am still learning about the line of tooling.

They are the same thread but have difference in appearance and construction. Like different lock rings. and a different numbering scheme.

Here are the pictures.

thanks for the pictures. hopefully it will help to get some answers. Iwill look through my notes and dies to see if the features match red head dies.

...looks like Ideal to me, but what do I know? Can you get a close-up or just write down all of the markings?

Froggie,

that is what I was thinking also, it does look like ideal.

is the die a MR die or is it a straight thru boolit sizer die? If it is not cut for a cartridge,the bullet sizers would have diameter marked and could account for the 300 designation. paper patched could use that size.

Just a thought.

The only markings on the die is 300, it is not a cast boolit sizing die. It is a muzzel resizer, i'm sure of that.

I was pretty sure you know what you are saying , but thought I would ask just in case. How does the knurling and dimensions compare to other ideal dies?

This could be one from the transistion period of codes to cartridge identification. are there any other dies for the 300 savage in the lot? I have seen a few dies sets for the change over that had dies marked with the codes and with the cartridge in the same set.

Does it appear to have a very light/ miss stamped lettering after the 300 stamping? I have one cmr die that is miss stamped.

Not sure any of that is much help, but we will continue to throw ideas at you until the real experts get here!

also does it seem to fit a 300 savage case?

www.castpics.net has a fairly complete reference to 310 tools.

The only markings on the die is 300, it is not a cast boolit sizing die. It is a muzzel resizer, i'm sure of that.

If it was produced on special order, of course all bets are off, but if it is a Muzzle Resizer, it should be marked MR or CMR. Is there a shoulder in it? Why are you so certain that it isn't a bullet sizing die that has lost its pusher rod? I've seen dies identical to the one you show and marked identically (except for bullet diameter, of course) with a fitted rod that looked like a big old nail with no point. They could be mounted in a press or set of tongs and used about like the current push through Lee dies. Just my thoughts based on the picture posted... you're there and I'm here, but that's my SWAG and I'm sticking to it! :coffee:

Froggie,

When I first look at the picture, my mind said that sure looks like the markings on a boolit sizing die. It iwll be interesting to see what the outcome of this die is.

I called Rick at the 310 Shop and picked his brain for about 30 min. He thought it might be a custom order of some sort. Im going to send it in to him for a look and see what he says. I will update the post at that time. Thanks for all the help guys.......as usual.

I also have this "300" sizer - were you able to get a response from Rick?

I'm no seasoned expert (novice, actually) on the 310 but there was no pusher rod in the Lyman box and I think this to be a muzzle resizer, too. The only other items in the box was a #18 priming chamber (.348win) and a 118 dac with a 413 seating screw (7.62). I had assumed this to be some sort of a .300 Win Mag git.

There is a shoulder in the "300". The top opening is .324", the bottom is .485". The shoulder starts to neck at .875" from the bottom.

7.5x54 Fan,

I believe you have the answer. It could be a 300 mag mr die. that die would likely work for most 30 cal magnums of the time (300 win, 300 h&H, etc...)
the dac marked die is a double acting crimp die or seater die. I will have too look up 118 but 8x57 stick sin my head 118. the 413 seater stem would be for the 308413 or 311413 depending age of mould.

You are correct sir. In the sets I acquired there was a complete 8mm box set (and others) with the proper 470 seating stem in the 118, but in a single Lyman box there was also that 118 with the 413 stem and the other two dies.

I rediscovered the box doing some spring cleaning; I'm as curious as reloaders4you to what the "300" is truly meant for.

This is what I got figured out with the die.
