Deflave:
As for as numbers go, I am getting:
1503 fps with 135 JHP
1250-1300 with 180 JHP
1190 with 200 JHP
Power pistol and 800x.
I do believe these #'s are well past 40 S&W territory. Do not get me wrong I like the 40 S&W but it is not in the same class as the 10mm
Those are good numbers and best the .40 for sure.
But I've seen plenty of 180gr. factory loads average just north of 1,050 and 155gr average just under 1,300fps.
My point is that I just don't see the juice vs squeeze with the 10mm.
