I was looking around the web, searching for a new mold, and I stumbled across an Ideal/Lyman 431244 mold. The pic of the mold shows the numbers and the mold is for a plain based bullet. All refrence to 431244 have linked the mold to the 429244 which is a gascheck bullet. I can find no info on 431244 in my literature nor on line searches. I doubt if the mold was altered, so what am I looking at?

Thnx...

1. Came off an EBAY listing from some time back. Can't verify the veracity of the information
2. Cast Boolit post
Hope these help you.

1. LYMAN Bullet Mold #431244
44 mag 255 grain 2 cavity Gas Check

2. Cast Boolit: post of floodgate (8-29-2007 )
I dug into my Lyman files, trying to chase this down. The Ray Thompson gas-check SWC designs #431215 and 431244 were first shown - under those numbers - in Ideal Handbook No. 39 (May, 1953), and appeared again in HB No. 40 (1955) and in a fold-out chart of Lyman-Ideal bullets dated 3-56. In the First Edition "Handbook of Cast Bullets", dated July, 1958, page 89 has a writeup on these bullets by Thompson, listing suggested loads for them (as well as #358156, and #452490, similar designs for the .38 / .357 and the .45 ACP / AR) where the two .44 bullets again carry the "431-" size-to prefix; BUT, the detail bullet pages 150 and 153 show the same bullets as #429244 and #429215, respectively, as do all the Handbooks from No. 41 (1957) on. So the change must have occurred in 1956-57 or so (allowing a little lead time for Handbook collation, editing and printing). Does your #431244 have the vent lines? (These seem to have been introduced in the early-to-mid-50s.)

The modern Lyman equivilant is, indeed, the 429244.

Ideal's first three numbers, sometimes, reflected the actual boolit size. But not always. I have a ventless Ideal 308291 that Lyman labels 311291.

It's not always logical.

I've cast with a 431244 and several 429244s. If you get .431" out of that mould, you're lucky. Mine ran right at .429"./beagle

Hmmm, I have a 429244 (gascheck version) that works well, although it's a single cavity so I don't have many on hand. I believe I was looking at a bullet mold site that linked me to an ebay sale. The pics are pretty good and I checked the numbers on the side of the mold and the cavities were indeed plain base. mebbe I'll bid and if I get it cheap I can find out just what it is. I could use another 255 gr SWC plain base!

Begal, is your 431244 gas checked or plain base?

The ones that I have now are GC'd. I've PB'd a 429215 but not a 429244 yet. Should do all right. Think maybe we PB's a 429244 for Shuz. Maybe he'll see it he's not down south laying in the sun./beagle

Same design, not necessarily make the size that the first three digits have. I have a 429244
and 431244 and they throw (based on memory here) about the same. Of course, these are
the Thompson 250+/- gr GC design. Nowdays, I don't do GCs for pistols, no gain for the
hassle and expense, IME.

Saw that mold on e-bay and figured someone had the upper surfaced milled down to remove the gas check section

Yep, saw it this morning and had the same thought.

I agree with MtGun44, no need for gas checked handgun boolits, so sold the 429244. It is a nice design, though.
