Need ID on old brass mold

[Boolseye]

Hey guys-what have I got here? Given to me from the odds and ends box at a local dealer.

I don't think that's a mould . It fits the description of a false muzzle for a muzzle loading target rifle .
I never had any details as to how they were actually made but something along the lines of the muzzle being back bored just enough to start a ball and align to the bore , then drilled for alignment pins and cut off . Making it an exact fit to it's particular rifle . It was used both to protect the crown during cleaning and to precisely start a bullet with no tip and no possible crown damage .

I agree false muzzle. the thing sticking up is a blinder. it blocks the sights so you don't shoot the false muzzle down range. there should be signs of pins on the one end of the muzzle.

Interesting. Thanks, I had no idea.

Wow. I learn things here everyday!

Would be interesting to know the hole size and see the other end also. I believe it may be a false muzzle but being made of brass I question that some.

Heard of it, but never seen one, thanks for posting the photos.

[Boolseye]

I'll put up some more photos later.

I was under the impression false muzzles were made from a section of the rifles own barrel for concentricity.

It’s a .30 cal hole.

Here’re a few more angles:

What does the inside look like?

It appears it may be a smooth sided mould for a boolit of some sort (diameter?). I've seen pics of some old simple moulds like that though usually there is a sprue plate or "cap" to pour through then break off the sprue.

There is no way to get a flat base without a sprue plate or cap.

I make smooth sided moulds much like the old Ideal Cylindrical Molds but they have a sprue plate and nose form/ejector pin to push the boolit out (base pour).

Some have made basic moulds like that that just depend on lead shrinkage for clearance for the boolit to drop out but again normally have a sprue plate. Here is an example DoctorBill made (post #92):

What you have could also be a crude core mould for swaging as well.

The mystery deepens!

I too thought that false muzzles were made from a section of the rifle barrel. Stating the obvious, without a hole all the way through, that cannot be a false muzzle and is more likely to be a mold of some sort.

[Bazoo]

Probably not a gun related mold I'd bet. Maybe for a small weight for a model car or boat or an internal weight in a fishing lure.

If it doesn't open it's not a mould. Filling that with lead would just be a hole filled with lead, and it would be no small task getting the lead out.
I'm unsure of it's real application.

You didn't look at the link I posted. There are indeed moulds that do not open and some that do not even have an ejector, the boolit just drops out through shrinkage and gravity... but any I have seen do have a sprue plate at least.

Ideal used to make cylindrical moulds that didn't open:



The ones I make are similar though much beefier. No need for it to open.

However, this one not having a sprue plate, I doubt it is a boolit mould. Core mould maybe. Or...?

The inside looks like nothing more than a hole, somewhat blackened-perhaps with enough carbon added a slug can drop out?

Why don't ya try casting a couple with it. Fill it up to the mouth. If you pour over you can scrape it quick with a stick. Maybe the size of the resultant casting will lead to the answer. Probably been smoked to make it release easier.

[Boolseye]

Ha, great minds. I was thinking the same thing, I will.

Maybe I should have made my question clearer... does the hole look like it was drilled (beveled bottom), flat bottom or an ogive like shape like a boolit nose? If it has a "boolit" shape to it then it could very well be a crude boolit mould.

If plain drilled or flat bottom then is is likely an attempt at a core mould for swaging... or maybe something entirely not shooting related. It is likely a mould of some sort since it has that tab attached. It would be kinda thick walled for a scoop!

My thoughts anyway for what they are worth. Just a WAG.
