... 120-125 gr truncated cones. Something like the Lee 120 TC....
Used that type of bullet (Lyman), years ago for a Walther P38 WWII issue. Also, used in in a Smth & Wesson M59, and a .38 Super Colt Commander.
It fed fine, shot accurately enough, but I had a heck of a time handling them when hand loading...they would slip from my fingers, making it difficult to load into the cases. I do not have that problem with 9MM 125 Round Nose bullets.
