Parker Hale 58560 Mold - grain weight for projectile

[gjkershul]

I picked up the top half of a Parker Hale .58 Minie mold at a gun show last month. Not having the bottom plug I tried my bottom plug from a Lyman 575611PH mold. It was too small.
I have an old 500 grain RCBS Minie mold from which I tried the bottom plug. It fit. Also, I found the RCBS mold screws going through the mold handles and the attached RCBS plug plate plug worked. Makes nice bullets now. When I get a scale that weighs over 500 grains I will find out what weight it casts now.
Does anyone know what weight projectile the Parker Hale 58560 mold is supposed to cast in its original configuration?

I had a couple of moulds given to me with no bottom plugs. I sent them back to Lyman with a request to fit them with base plug. They sent them back to me for no charge with new base plugs.

Don't know if they still do this but they did for me.

I have the same Parker Hale mold, and my bullets weigh out between
556 and 560 grains.
