I loaded some 142gr LRABs in my .260Ai for the first time. I started with my standard 140gr load of 48.5 grains of H4831SC, which is a slightly compressed load. I stared with the same length, base to ogive as my Berger and SMK loads. In loading these, all bullets were left with a significant "ring" impression in them from the die. I have never had another billet with a jacket that seemed that soft? Has anyone ever experienced the same thing? I haven't shot these yet, should that affect accuracy?
 
They are soft I've had the 168 do this with compressed loads..I've had this happen with the Amax bullets also..
 
Are you using a standard or VLD seater? Whichever you're using it might well be worth it to try the other.

Are you seating to this specific length for a reason? Do you have any room left in the mag box? To the lands?
