Make sure the first loaded round chambers before you load the rest. I only crimp straight wall pistol rounds and I have never had a problem with rounds being too long, but I don't load heavy for caliber bullets or have a gun with a short cylinder. I have read people with some Freedom Arms revolvers write about having short cylinders for the long, heavy bullets.
