I am looking for a .570 round ball mold, anyone have any for sale or know where one might be available. That size seems a little hard to come by.

I saw one about a month ago on the shelf at the Log Cabin shop in Lodi OH.
It was around $100 but new.
They are real hard to find.
Sent you a PM

Titan has LEE 2 cavity molds in stock in.575. Have no idea if you can use that diameter.

May I ask what your plan is?

I bought a box of commercial ones with plans to try as a round ball in a 20 gauge shot wad in a rifled barrel, but haven't gotten to it yet. A .60 is too big for a shot wad and too small to be a full diameter one.

I have a Sante Fe Hawken, that we rebarreled with a 58 caliber Sharon barrel. I thought that a .570 ball would be the best size for it. I do have a lyman .562 mold and will try some of those first.

I must admit to not having done much with patched round ball in muzzle loaders, I've mostly used conicals. Can a diameter that's less than ideal be compenstated with a different thickness of patch easily enough? Guess I should learn a bit more about the internal ballistics of muzzle loaders.

Generally the ball is ten thousandths smaller than the bore diameter and the patch about twice that much thick, but groove depth and each barrel's particular likes determines what works best via result on target. If the rifle has very shallow grooves and fast twist (like 1 in 48") like those intended to be loaded with conical bullets, it might prefer a larger ball and thinner patch than a barrel with deep grooves. I'd start at .575 for the RB and a .015 patch. .562 might work with thick cotton twill (denim), whatever it takes to make the ball an extremely tight fit.

Every Sharon barrel I've slugged (maybe a dozen) has been right on the money (.58 measuring .580"). In those barrels I've gone with a ball .005" under nominal bore diameter, with an oiled patch running from about .017"-.019" thick. Your barrel should be a 1:72 twist, so it is probably going to give best accuracy with what are often considered "warmer" charges, around 1,800 fps.

In a .58, that combination would probably be a nominal .575" ball with a pocket drill patch lubed with neatsfoot oil or olive oil. ToTW has the Lee .575 moulds in stock. JoAnn's Fabric has pocket drill in bulk https://www.joann.com/jo-ann-stores-unbleached-drill-fabric/683532.html

If you decide to try the .562" balls, 10 ounce denim usually runs around .025-6", 7 ounce denim usually about .019-20".

I did see that the Lee .575 molds were available. I think I will get one and try that too. Trying to get this rifle ready for an elk hunt this fall.
I do have a few other rifles with Sharon barrels, they are my favorite barrels, wish they were still made.
