Yes, different type bullets should be checked. In the video they obviously jammed the bullet into the lands using the OAL gauge, the bullet stuck and was the longest reading. When I check I have the muzzle pointed slightly up and take measurements with the bullet coming out with the case and also slightly sticking, generally within 1 or 2 thousandths of sticking and not sticking.
Like I said either method works. But using jam, the amount of neck tension is going to change how far the bullet goes into the lands before it sticks and your basically finding the point you want to stay away from, then back off .020" to start finding a seating depth that works. You'll never know if your in or out of the lands with that method. You can not use others info on various bullets when it comes to jumping or seating into the lands and by how much.
I think using touch is just a better way to share info and can get you to finding seating depths for different bullets faster, easier and cheaper in a lot of cases. It's also good to know if your in the lands for powder charge. I will back off a little if I know I'm close to or into the lands.
