[QUOTE="Frog4aday, post: 1670464, member: 9308"] Here is the advice from Berger bullets on finding the best seating depth for a TARGET load (not hunting.) [B]"Trying to find the COAL that puts you in the sweet spot by moving 0.002" to 0.010" will take so long the barrel may be worn out by the time you sort it out if you don’t give up first. Since the sweet spot is .030" to .040" wide we recommend that you conduct the following test to find your rifle' sweet spot. Load 24 rounds at the following COAL if you are a [U]target / competition[/U] shooter who does not worry about jamming a bullet: 1. bullet 'touching' (jammed) into the lands 6 rounds 2. 0.040" off the lands (jump) 6 rounds 3. 0.080" off the lands (jump) 6 rounds 4. 0.120" off the lands (jump) 6 rounds"[/B] Once you fire these 24 rounds for accuracy, you will know which seating depth your rifle likes best with the 147 grain ELD-M bullets IN YOUR RIFLE (they are all different!) I know you are working in metric system (millimeters) so you'll have to find an online conversion calculator to figure out what all the "inch" measurements would be in "mm", but this should get you fine tuned on seating depth.
