I found a couple of bullet molds at a gun show and the only marking is "c martin" on the sprue plate. All are two cavity molds, .458 diameter, some are bore riding nose, multiple narrow lube grooves or wide grooves, one is a gas check design and the bullets range from 490 grain spitzer to 560 grain gas check. Very nice bullets and someone has to know this maker. Very nice steel molds. I would like to know who the maker is and if he/she is still making molds.
Thanks for your help.
