I just purchased , from S Mac , a nice NEI , .30 cal double cav. mould.
It is a bit unusual in that there are two different weights cut in the same mould block.
Many of my .30 cal. moulds cast a nose that is far too large for my many 30-30 rifles that have basically zero throat. The bullets from this mould should chamber fine in my rifles.
The first few I cast measured .3095 X .3105 " with my range scrap alloy.
I decided to lap both cavities ( slowly with several measurements to insure that I didn't enlarge the mould too much ) . The lapping was a great success. Now both bullet weights size to a nice round .311".
