Before a person starts reloading a cartridge, they should know thier max OAL for a particular bullet

Take a dremel tool and an empty fire formed case. with the disc cutter, cut thru the neck and shoulders. Now you could be able to insert a bullet and it should be tight enought to hold the bullet but loose enough to slide when you push it. Now chamber it and carefully remove, and measure. Do this a few different times. I find .005-.010" crushing factor. So you can subtract .010, and this is max COL.
