SRH 44 Cylinder Throat and Bore Diameter for Mold order purposes
« on: April 29, 2008, 02:47:11 AM »
I'm hoping to get into casting my own bullets for my SRH, and would like to purchase a mold. Is there a generally recognized standard cylinder throat/ bore diameter that can be used?  I was not sure if I should go with .431 or .432?  I guess I should really slug both to find out if there is a lot of variance.  Any advice would be appreciated.  Thanks!  Jim

The default for best accuracy/least leading is to match the throat size within 0.001" or less.  But check the bore diameter - if it is much larger than the throat, accuracy will suffer and leading may occur sooner.  Unfortunately this happens more often than it should - two of my own Rugers were so afflicted.  The solution then is to ream out the throats to match the bore and cast accordingly.
