[QUOTE="Boozer, post: 1105168, member: 22146"] Maybe I should briefly explain how the tool works. The primer pocket is enlarged to 7/32, and the OD of the alum tube is 7/32, and is a snug fit. The flash hole is drilled out and tapped for 10-24 threads. The all thread fits perfectly inside the alum tube. You use the alum tube to push the case tight up in the chamber, and then screw in the all thread in, which pushes the bullet out until you feel the bullet contact the rifling. As I'm performing the test I am pushing on the aluminum tube, which keeps the case push snug against the shoulder in the chamber. I can (conveniently) see the base of the case through the small hole in the side of the action, and can tell when the threaded rod pushes the bullet into the lands and wants to start backing the case out of the action. Since then theads hold everything in position, there's little chance of anything getting thrown off as the assembly comes out. If there was any change it would be due to a slight rotation in the rod, and would change the measurement by maybe up to .010, but certainly not an inch. Both the remington factory round and my seating depth round are being measured with a hornady bullet comparator gauge. Both measurements shown above are CBTO. I have scratched my head and repeated the test multiple times with the same results. I appreciate all, the feedback, and trust me, I HOPE I AM DOING THIS WRONG, but I just don't see how I could be...
