Missing Lyman top punches (TP to mold table)

Its late and I'm quite tired.

If you know of a related mould that drops a bullet of the nominal diameter and that uses a listed top punch, please tell me.

I guess I don't understand what you are asking, are those numbers for the TP or a mold?

The 228 367 mold used a 450 TP.
The 257 325 mold used a 438 TP.
The 257 388 mold used a 450 TP.

Is that what you are looking for? I don't think there are TP numbers 367, 325, or 388 as Lyman used TP's that were already numbered.

[BCall]

I think I finally see what you are asking. You are referenceing the seating punch for the 310 dies as the same as top punches. They are not necessarily the same.

For instance, the 228 367 for the 22 HP calls for a 376 seating stem for the 310, but it uses a number 450 top punch in a lubrisizer.

If you look at how you have it typed up, you can see that they are mold numbers. Like this-

6.5 Jap 0.266 469
6.5 Mann. 0.266 469

They are referencing the 266469 mold that uses a 310 seating punch #469, but a lubrisizer TP #455.

Have I been confusing enough?

Hit the submit button, it disappeared, and I really am submitting... again...

OK, so you want the jury to believe the Ideal Code is DDD-CCC, where CCC is the corresponding 310 Seating Screw for cast bullets?

Interesting... So this should result in more moulds being identified. Hmm, Top Punch, mould, 310 cast bullet seating screw table?

:not listening:

Geesh. Now if this is correct, after some hand to keyboard death match, I should be able to correct some things....

The 310 seater stem, 310 cast bullet sizer punch, and some top punches are fit to the bullet and use the numbers after the diameter as the reference. Do you have a set of the original tables for the 310 tools? You will see this pattern in the tables.

As BCall said this falls apart after a certain point with the top punch used in the cast bullet sizers. In early documents each part had a designation. Ever wonder why the sizing die and internal punch are referred to as H&I dies? Well you just found out, H&I are part number designations in the parts diagram. The top punch also has a designation. You may find it in some of the older tables. Then the company realized that the top punches might fit more than one bullet adn now you have the situation that BCall mentions.

Top Punch "G"
Body "H"
Punch "I"
310 expanding chamber [M die] "F"
5/8x40 to 7/8x14 is "K"

Has anyone done an illustration of the code? Be nice.

Lyman 1958 Handbook of Cast Bullets, pages 82-86, contains a table of mould, diameter, top punch, and seating screw.

I tracked down the associated top punch and seating screw info for most of the missing cases. but there are a few that don't fit...

303 Brit. 0.313-299
311299 casts .312

38/55 0.379-296
375296 casts .382

401 Win. 0.412-426
410426 casts .409

30 Luger 0.311-244
311241?

32 Auto. 0.312-252
311252 casts .312

[scrapcan]

The number in your list is the suggested sizing diameter for the cartridge, the old ideal and lyman tables used that nomenclature. You will also see some tables that show the suggested bullet that be used. in your example for the 303 brit you would use 314299 mould, size to 0.313 in bullet sizing chamber, and use the 299 sizing push rod or top punch (part G if using a lubricator sizer).

You must be careful when discussing the 310 dies as they also have bullet sizing chambers that could be ordered ( in years past) in just about any size one would want. Also note that the cast bullet sizer die punch had the nose cavity in it and the bullet is pushed base first through the die. They are not nose first sizers as designed, the base first sizing was meant as a means to seat the gas check in the same motion as sizing to diameter.

There was a discussion on this some time back. Some of the earlier mould numbers by idea used a nominal bore diameter as the numbering. Some used the bore diameter versus the groove diameter. And some just used a nominal number for guns it might fit. Today is no different, for instance do search on lyman mould dropping small.

Another one is you will see 308466 on some old moulds, the new number may be 311466.

The adapter should be 5/8x30 as that is the thread on the 310 dies, it is a holdover from the founder of Ideal having spent time at winchester according to historic accounts.

[ohland]

Close enough.

[ohland]

in your example for the 303 brit you would use 314299 mould, size to 0.313 in bullet sizing chamber, and use the 299 sizing push rod or top punch (part G if using a lubricator sizer).

After looking at the Ideal reference, I posit that the mould could be identified as:

Cast bullet diameter, then listed seating screw (cast)
Failing that, jacketed diameter, then seating screw (cast)

Thanks to Dark Canyon, there is an electronic copy of the table from the 1958 Lyman Handbook of Cast Bullets.

The attached file is an Excel spreadsheet of:
http://www.darkcanyon.net/lymancastbulletinfo.html

I tried text delimited with tabs, but it formats poorly.

To use or misuse: sort for whatever you want, mold, top punch, or seating screw. Let the computer do the work.

BUT... this does not add the recent Lyman mould stuff, I don't remember seeing the 600 series of top punches...

Now to grab the list from castpics, populate all top punches to sort with... don't know if anything can be done with the seating screw for those...

:idea:

[ohland]

Formatting sorta coarse. There is a bit of border confusion at the bottom where I imported the Castpics info. But... I think it's pretty much done. Some poodle faking, adding weight and style.
