According to my manual, max OAL of 40sw is shown as 1.135". Because of the risk of pressure issues in the .40 Glock, and bullet set back, I generally load at MAX OAL or longer for safety margin.

I loaded some dummy rounds to set my dies and see if they chamber in my glock 23. The glock magazine will function with rounds loaded at 1.165", and they will chamber fine. This exceeds the listed maximum OAL at 1.135". Can I use this OAL and work a load for it, or am I loading the bullets TOO long?
