Here is another method to get your measurement of where the lands of the rifleing start.

If you remove the bolt, and making sure that the gun is unloaded, Drop which ever bullet, not loaded round, you are thinking of shooting down the tube nose first. It will stop when it gets to the lands. At this point apply a small amount of pressure to the base of it with a wood dowel or pencil. Now slowly slide a cleaning rod in from the muzzle. You will feel it hit the tip of the bullet. With a marker, make a mark about 3/8" wide in the area just inside the muzzle and continue to just outside the muzzle. This will allow you to scibe a light line in the dried ink. Once this is done then pop the bullet out of the chamber and reinsert the bolt. Repeat the above proceedure and make and scribe another mark. Now with dial calipers you can measure the distance between the marks and get a good OAL to the lands of your rifle. It might not be within .001" but it will be close enough to know where you stand with the loaded round.

I know this sounds like a lot of trouble, but it only takes a minute or two to complete and can be done with items already on hand.
