What you say makes sense about the fps. I never said it was the Norma load, but I also never heard of a 10mm especially back then being that under powered until more resent years as option's increased and got popular. ... Yes OW actually made the round under design contracted by S&W. ... True about the .357 sig, I didn't mean you could make a .357 sig out of a .40 case. Just OAL is the same with higher ballistics because of the bottle neck design. My Sig 226 is a .357sig. I have the .40 barrel also but it doesn't perform like the .357sig round. .... My friend is pushing 70 right now, He was in it before the switch and long after it, retiring late 90s early 2000.
There’s a reason it's called the “FBI Load”.
