Land-to-groove measurements on .45's
« on: July 28, 2007, 09:20:50 PM »
     Hey all,

     To all here that have slugged their bores; what are the land/groove measurements of your .45ACP and Colt .45 Revolver barrels?    What diameter of bullet works best in it (.451, .453) using lower-velocity charges?  Thanks in advance.
