Although I haven't started reloading (yet)...I came across some old ammo that I don't remember if I set aside as previously chambered rounds or whatnot (been gone for a while)....
I got the calipers out to measure the OAL and got some varying results. I set that ammo aside.
Since then, I've bought some Winchester defensive rounds (PDX1, JHP,165gr), and for grins, took out the calipers again to measure OAL "straight out of the box". Again, I got some varying results.
The shortest OAL was 1.1135
The longest OAL was 1.230
What is the accepted range of OAL for .40 S&W rounds? I've done some searching on the interwebz....but haven't found my answer.
