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 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.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 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.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".
