There's a basic rule of thumb when determining whether to neck, or full length size.
If the ammo you are loading will only be fired in "one rifle", fired brass from that rifle needs only to be neck sized. This will correct for head space problems in that rifle.
If the ammo may be used in more than one rifle of that caliber, and you do not know which rifle fired it the last time, full length size.
There is no associated problem with what kind of action the firearm has, as it applies to how you size it.
Fired brass from a particular auto loader, when necksized, and fed again into the same autoloader, the round will chamber perfectly.
