I purchased this mold a few weeks ago under the description that it was a .31 cal. Once I received it, I cast some bullets and it appears to cast .36 and .44 bullets not .31.

Does anyone have the history for these molds? I have seen molds stamped .31 PKT and other calibers, but there are no markings on this one. Why the different calibers in one mold?

Someone repurposed it along the way. No need to mark the new size, they new what they did. Whoever sold it to you did not bother to check it. They show up like this from time to time.

How could you repurpose a mold like this? Everything seems to line up...

Use a hand grinder with a small round stone to ream out the ball area and a few other small cone shaped stones for the bullet.

The marking should be on the right side, by the hinge. As you stated, 31P or 36B (b for belt ie the 1851 Navy), 36P (36 pocket) or 44H (for holster). Look real close with a magnifier.

I can't see any stampings, and the only ones that are visible are the Colt Patent on the cover.

The 0.431" is small for a 44 Colt. It should be closer to 0.450". The 0.372" is about right for a 36 caliber Colt.

I agree with dandak, as there should be such caliber stampings. But I've seen many iron molds where these markings just rusted away.

I am sure there was. This sucks because I was hoping to use this for casting roundball for my 1849. The Lee .31 mold I have seem to cast balls fine, but they are too small for the cylinder. They move even with grease on top of them if I try to load more than one cylinder.

Here is the way I keep these bore sizes straight. The "bore size" is roughly the diameter drilled through the barrel. That is what Colt calls the "caliber" on early guns. BUT, then the rifling is cut through, so now the groove to groove diameter is larger.

"In the beginning" we had flintlock muskets. The military called them 69 or 75 caliber. Fine! But then when rifling was added, they were still called 69 or 75 caliber. I call it an unchanging "Tradition" of terms, although it doesn't make sense now. A stairway in a Navy ship was still called a "ladder" only a few years ago.

So whether it is an early Colt or Remington percussion, 31 is 32, 36 is 38, and 44 is 45. The confusion carried over when these guns were converted to cartridge. The 44 Rem, 44 Colt, and 44 Rimfire were closer to 45.

Not all COLT'S PATENT molds were marked with the caliber. I have several unmarked.
In an earlier post I said the mold was repurposed to cast different projectiles, I probably should have used modified.
