Is there such a thing as .411" round balls?

[Texas by God]

Or moulds for them? I've enjoyed RB loads in .30-30, .38 Special, .44's,etc. and I'd like to do the same for .41 mag. Thanks!

Track of the wolf sells .410" round balls, $11 per hundred. For molds you can either order a single cavity from JT ball molds, or a multi-cavity from Marty's arms. Both makers list based on the cavity size, not the ball size. You would likely want to order a .414" cavity mold.

Thank you, Sir. What’s your opinion of Powder coating the .410” balls up a few thousandths?

That is what I would do. The only thing to be careful of is that you want straight cast balls. If what you are buying is swaged, they are typically coated in graphite and may not take the coating well.

RCBS also makes a double cavity mould for .410" rounds balls. I bought one last year to use in my Lee Enfield No. 1 MK III in .410 Musket. They don't run that particular mould very often so I had a hard time finding one available for sale, but in the end I did manage to find one. I cast them out of soft lead for use in my smoothbore Musket, but in a harder alloy you might get them to cast at .411" or .412"?

Lyman/Ideal used to make them.......I would bet there are some out there!

Beagle or lap out the mold and 412 is easy.
