For OAL I set my bullet seating die up using a factory round of the same bullet profile then I made a dummy round (no primer and now powder). Next I dropped them both into the barrel of my disassembled pistol and compared the results looking for how freely they dropped in and how much of the bullet was still visible out the back of he chamber. Lastly I put the live round away and assembled the pistol and chambered the dummy round from my magazine then ejected it by hand cycling the slide to make sure it functioned. I keep that dummy round to check my die again every time I pull out the loading gear.
