Hello, I have been reloading on and off for many years and never really took the OAL very seriously. As long as it was within sammi specs it was ignored for my revolvers. With the automatics, i have read listings of max oal in the reload manuals and most of the time they are too long for the magazines close to specs.
So i change the oal to the maximum that will cycle in the kimber 45 acp and 380 auto magazines and pistols. Is this proper procedure or am i increasing the pressure too much if i make a .025 oal length change to the smaller side.
the casings after being fired show no excessive pressure signs.
thanks john
