41...I make most all my own cast bullets but I think I did get some 10mm bullets from him a while back...very nice bullets. Talked to him for a while and turns out his favorite caliber is .41 Magnum which is why he has so many designs available...
I have two .41 Specials...a USFA Shooting Master 5.5" that David Clements made up and a Uberti Cattleman 4.75" SAA that Jack Hunting just finished. Those two and three Taurus Trackers all eat up Specials...
