Imagine the possibilities

[Doug Lee]

What equipment is necessary to increase the diameter of a cast bullet, for example from .427" to .429"
Thanks,
Doug

a larger mold?

To "smush" existing bullets to a larger diameter, you would need a punch & die set and I would expect it would have to be custom work, fitted for the bullets you have. Not cheap.

Cheaper and simpler is just get a mold that drops the size you want, or slightly larger and size them down. Getting an undersized mold honed out may be a possibility as well.

you could cast a few bullets, drill and tap for some threaded rod, and lap the mold with some fine metal polish to try and increase the size of the mold itself so it throws the right size, or just over.

Try doing a google search for 'beagling a mold'.

Couple of coats of PC may bring your size up to desired diameter

Thanks all for the responses, I was thinking along the lines of what 44 AMP said, smush it down and run it through a larger sizing die.
Really not practical. . .

Powder Coating will "effectively" give you what you want.
I suggest Eastwood Ford Light Blue as foolproof/simplicity (if you're just starting.)

Cast-off toaster oven + THIS
Remember to let the oven come up the a steady 400-420 degr first

A hammer...

That's also a great suggestion, powdercoat a layer or two and get a larger sizing die.

 

[mehavey]

Just one PC* layer will do it.
(trust me )
