What is this tiny boolit?

[Rusty Goose]

I have this very old two cavity mold, one cavity is a .333 round ball (00 buck). The other is a conical bullet .333 diameter and weighs in at 37 gr. It has one lube groove. What shoots such a tiny bullet? .32 rf?

Does it look like this? If so, it is for Muzzleloaders.

Sounds like it could be for a .31 caliber colt revolver. Colt made molds for there different revolvers that had bolt a conical and ball cavity. They were marked colts patent on the top of the sprue plate.

There are no markings on it at all, no stamps. It does have a primer seating provision.

It is for a Cap and Ball , percussion revolver such as those made by Colt .
Small revolvers were chambered in .31 cal . The moulds for these and 36 cal revolvers usually had one round ball cavity and one conical boolit cavity .
Usually the all metal iron moulds , if used much at all , will have had wooden handles attached by the caster ... the all metal moulds get hot fast and handles help you cast with them .
I have a couple of these moulds in both .31 cal. and .36 cal . all are iron and none have any markings .
I thought the 31 cal was , at first , a 36 cal when I saw it in a flea market and bought it ... even though I didn't have a .31 Cap and Ball revolver then (or now ) I bought it anyway because it was cheap ($2.50) and old-cool !

The wood handles on your mould may be factory or a good owner done set ...Like !
Very Nice ,
