Cold welding is very real.
Over the last 30+ years, I have discovered 2 things that reduce it to almost zero.
Firstly, my necks are brushed with very fine powdered graphite, not that lock lube stuff.
Secondly, my neck interference is NEVER tighter than .0025", learned a very valuable lesson here many years ago. Another story to be told elsewhere.
HBN coating is a real game changer for me, for my ELR 338 & 375 cartridges, it made a huge difference to consistency, ES/SD were lowered and all aspects improved, velocity, pressure and results on target.
I do not HBN coat all of my rifles, but have experimented with a few.
Now, my last words on this, if you are NOT dry lubing your necks with either powdered Graphite or Mica, you are doing yourself, and your loads, a disfavour. I have and do use both depending on my own outcome.
It is the best change you can ever make to seating. Period.
Cheers.
