I just use pin gauge to check the bore size.
They are easy to find on line and cost very little for what you are getting.

about 20 years ago I made a set of gauges on a lathe that measures a bore from one end to the other. What they are is a round medal disc turned to various diameters such as .550-560-565-570-575-580 , in between these numbers I have turned some .572-.577 etc. the center section is flat about 1/16 with the edges rounded, and center drilled to accept a musket ramrod threaded end. It doesn't take long to determine the bore dia. and if there is any irregularity from one end to another. For the center hole I bore a hole tap drill size about 1" deep and cut sections with a parting bit.
Unfortunately, I don't have access to a machine shop or know of anyone with a lathe. I am not familiar with pin gauges but all of the ones I see online are small diameter sets and are expensive.

You can buy larger size pins individually .575 to .580

Mike I found then on eBay individually for around 8 dollars each
Also amazon has then around 12 each

Lou what material where they made from. Think I may be able to have a few sets made at work.

I bought mine from Travers Tool. They are from 3 10 to bucks apiece. They suggested using "minus" gauges, aka class ZZ, which are a half a thousandth under size. This lets a .690 pin fit into a .690 bore.

I just got a Lyman 1-Cavity Minie Ball Bullet Mold #575213-OS 58 Caliber (575 Diameter) 460 Grain Old Style Mold and will cast some to try out but I haven't measured my bore yet.
I have done a lot of loading over the years but most of my cast bullets have been for cowboy action shooting and were cast by someone else. I have never seen or used a sizer. What kind of sizer would you you use for a Minie? Do sizers come with the ability to do different diameters? can you also size the bullets larger?
Thanks
Mike
