My Method to Find the ‘Lands’

Killick

Transcendental Capitalist
Size a dummy case with .002 neck tension (.282 for .284 cal.), mount your rifle, muzzle down, by the barrel in a bbl vice secured in an appropriate vice. Seat your preferred bullet long enough to be into the lands. If you don’t know what that would be try to find where the boat tail bevel is halfway up the neck by trial and error. Now coat the area where the ogive taper begins with a black marker. Let it dry and then drop the dummy round into the chamber and close the bolt. Open the bolt slowly and cycle it again. Now pull the bolt all the way out. The bullet will most likely be stuck in the lands. You can use a thin wooden dowel inserted from the muzzle to push the bullet up into the action to retrieve it. It will have bare spots engraved where it engaged the lands. Clean the bullet and seat it deeper by .010 increments. Keep repeating the process until the bullet stays in the case neck. Now seat the bullet in .002 increments until the lands no longer engrave the bullet ink. The last time it engraved will be your ‘touch’ point. You can now test for your optimum seating depth, either in or out of the lands.
OK, you can now respond with biting and incisive mockery at the utter naïveté of my dangerous and unusable newb method I’ve used successfully to produce championship ammo. Do your worst.

Perfect is good enough…. Just barely... {:~)

Seems like an effective and painstaking way to do it.
 
How many times did you watch it ? It's only an 8 min vid
2 things I noticed about EC's vid. First, he obviously didn't remove the ejector from the bolt which can possibly skew the cartridge when the bolt closes on it (if the bullet is not jammed in the lands). Second, he's not trying to find the lands. Jamb point is different than touch point. My method (not actually mine) locates the touch point. I shoot F-Class and don't need an ejector so I removed it.
