Latest update...the length to the lands is 2.30". Barnes (and John) recommends 0.05" off the lands, so I am seating the bullets to 2.25" and heading to the range tomorrow to re-shoot the 62-grain TSX's using CCI 400 primers and Varget, H335 and RL10x. I also made up a few rounds of the load that patterned 0.77" with the 450 primers. I'm going to shoot five at a seating depth of 2.25" ( the 0.77" load) and five at 2.23". The tech at Barnes said to seat them at 0.05" off the lands and, if that didn't work, try 0.07". My son just got his scope back from Leupold, so we're going to re-sight that back in on his 7mm Rem Mag. Gotta get that one right. He's letting me take it to Idaho next year in place of my muzzleloader. (I don't own a "real" rifle!)
