It has been edited out completely. I have edited this post so you can see at the bottom when someone edits. His original post was a fucked up looking drawing with a loaded round with a pistol case on the top and an "explanation" of what he was doing. No not a single person could figure out his drawing and what it was supposed to measure or do. Just because it is your first post and you post a picture that "seasoned" rifle and pistol shooters and reloaders can't figure out WTF it is does not mean you get a day off of getting taken to the shed. Reloading can be dangerous and misinformation can and will get you killed. If I am wrong then correct me.....

Don't believe OKIE2 has a drawing in his post, Wheres Waldo does. I think most people figured out what OKIE2 was trying to say. And what he suggested works very well for determining the length to ogive, cheap too!!!!
That was OKIE2's fourth post, looks like he got a great welcome with his attempt to exchange information. Hope he comes back. </div></div> </div></div>
I would think that rather than trash the guy, you might look to what he was trying to say.
You basically make a dummy round by cutting two or four slots down the side of the neck of a bottleneck case or down as far as a straight-walled case holds the bullet. Pinch it together so that it holds a bullet. Put that case/bullet (dummy cartridge) in the chamber of your firearm so that it extends past where you normally load it. GENTLY, push it forward until it seats all the way and the bolt is locked. Then GENTLY, unload the dummy cartridge, taking it so that it isn't ejected from the firearm.
Measure the OAL of the bullet. Write that down! If you didn't take notice the lands pushed the bullet back to this point in the case. Get it now? The OAL (overall length or overall ammunition length) is as far as the bullet can be forward so that the lands are touching the ogive. This isn't hard if you just think about it. It also doesn't take a $20 something threaded rod/plunger and a $6 dummy case in each chambering just to find where your bullet hits the lands. Chastizing over.
Now, take that same bullet (not a different one from the same box), slip it out of the dummy case. Back out the bullet seater in your seating die. Set the bullet (that very same one) you used in the dummy case and run the case up into the die. The bullet should have started to seat. Measure the threads of the bullet seater stem, i.e. 20 tpi will be .050" per turn. Turn down the seater until you get your bullet to where it sat in the dummy case, i.e. OAL in dummy case was 2.984, then run your bullet down to 2.984. That is if you want to touch the lands. You can also back it off to have the bullet seated in the lands or turn it in to back it off the lands. For those of you with a micrometer type die...just adjust it. I figure those of you who bought one probably know how to use it.
Edit:
A little hint: meplat uniformers work wonders when finding your OAL this way.
Also, if your bullet seater in your die tends to hit the tips, like on VLD's, spend a few bucks and change it to the type bullet you load.
