What would this bullet be called?

[bassncrap]

Had a bunch of stuff donated to our club and I grabbed a box of these bullets. Theres bout 30 of them and my caliper reads it as being .50.

But what type of bullet is it?

 

[tenngun]

Cant say for sure but in the eighties both Lyman and Lee put out a wide variety of conicals
As tge market decreased so did the selection

It resembles some of the Civil War era bullets I've seen for early cartridge rifles. Short and fat.

Looks like it was cast from a Big Lube, LLC mould but **** doesn't make a .50 as far as I know.

For short.....SORRY!

That looks like someone had a custom mold. Sort of looks like a modified Maxiball. I've never seen anything like that before.
Is it possibly this one from Accuratemolds.com: Bullet Design Details | Accurate Molds

That looks like someone had a custom mold. I've never seen anything like that before. Is the base solid or hollow.
