If you seat the bullet into the lands you could be causing high pressure spikes. If you are loading hot and jamming the bullets into the lands you are most assuredly running pressures well above the maximum for the round and possibly the rifle.
Seating -0.020 off lands but I have been loading 195 grain Berger EOL's and 180 grain Berger Hybrids in my 7 RSAUM pretty hot. I've been annealing after every firing. May try every other firing for the annealing operation. Thank you for the response SheepDog.
