OK guys here are a couple of pics of the homemade OAL gage I made from 1/8" brass rod a plastic sleeve on the end to keep it almost centered in the bore and two sight pin clamps from one of my bowsights. I hope the pics are ok. My wife takes them cause I'm not allowed to handle her camera. Obviously this measures from bolt face for one measurement and bullet tip for the other. After the OAL is determined to the bullet tip the same bullet is used to make a cartridge that length to the tip then a ogive tool is used to get the ogive length for that loaded cartridge. Now I can measure the rest to the ogive for a more consistant length.
