Lyman mold with two different cavities?

[richbug]

I bought a box of Lyman molds, and found one in it that I hadn't seen before. It has a 287442 and a 311413 cavity. was this a normal thing to have 2 different cavities????

I would prefer it had two cavities that were easier to identify, these two look basically the same but are 10% different in size. Kinda tough to sort.

Yes, back in the "good old days" at least, Lyman would do this on special order. I even acquired a 4-cavity mould with FOUR different .38/.357 cavities: #358344, #358429, #358495 and #357446, from a member here. In your case, the customer evidently liked the "Squibb" profile of #311413, and wanted a similar bullet for his 7mm whatever. They would also make different weights of the same bullet, by cherrying deeper or shallower; I have a 2-cavity #311241 RN plain-base cut to 125- and 150-gr. lengths, and so-marked.

If the similarity of the two boolits in your mould causes confusion, just cast one cavity at a time

Thanks, that is the info I needed.
