Thread: Full Length or Neck sizing. What is better and why?

Greetings All,
Until recently I neck sized most of my cases, mostly using cartridge specific neck sizing dies. Recently I have moved over to minimal FL sizing using the Redding competition shell holders as I have found it hard to get consistent shoulder set back by just backing the FL die of the shell holder and it is a pain to constantly re adjust the die when there are multiple rifles for one cartridge. The only problem that has shown up is with the 6.5x55. It appears that the yanks use a shorter measurement head to shoulder for this cartridge than the scandinavian countries. My T3 has a tight chanmer but still needs the +010" shell holder to get close to the 0.002"shoulder bump, its about 0.003". This is with Redding dies, some older Lyman dies are worse. Both my M38 and a friends Ruger 77 have chambers longer by about another .004". For the old soldiers and their light loads I still neck size. For the .303 this is with a Lee Loader.
Regards GPM.
