This bullet measures .506 x 1.013 x 384 with a cavity depth of .381. The base is very round and is a very accurate measurement at .506 (.505, .506, .506, .508). I have added the base photos with a flash and without a flash.
Any comments or thoughts with the small diameter other than JA3R?
Any MM/TT/TS/RBTRF numbers to assign as a variant?
