I have read every thread I could find on this site and a few others trying to find info on loading this projectile, lots of into on scentars, amaxes but not much on the SMK 123. I got everything nailed for the heavies in the other thread I posted, one thing that sticks out to me is the importance of seating depth. I picked up a load recommends at 39.3 gr of Varget or 44-45 of H4350 as a node to work around. What I cant find is seating depth, is it jammed or off the lands? Thanks in advance for the info and thanks for all the other info I have harvested here, it is a great help in spending my beer money on something other than beer.
