Thread: 7mm RM 162 Amax

Can only guess where your 10mm deeper seating would be but I would seat for a starting point, in your case, so that the point on the projectile where it changes from the boatail section to the parallel shank lines up with the shoulder neck junction on the case. Assuming your powder charge is not being compressed by this seating depth - it shouldn't be. With your long throat I wouldn't even bother chasing the lands. I have a 22/250 that I cannot get within cooey of the lands and it shoots exceptionally well still. A cartridge loaded as shown in your photo with the projectile so far out, if dropped on the floor, would develop a severe case of runout/wobbles. When dropped they always land on the projectile end of course. Also consider when developing a seating depth the max mag length limitation.
