My question is- what am I missing here; the only reason I can think of for full length sizing is to prevent issues with the brass not fitting in the rifle's chamber (for a bolt action for target shooting). I have a quantity of once fired .300 Win Mag brass for my new to me rifle which was not fired in the rifle.
Happy to full length resize this time if necessary, but prefer neck sizing and trying to work out why I shouldn't.
I would always full length size once fired brass from another rifle at least the first time, then at least you don't go all the way through the process to find out later that half won't chamber, for example one of my .308's produces cases that won't chamber in the other, same make model and calibre ! not a problem if you full length size, but a buggerence if you have neck sized them! start from a known point and the worlds the mollusc of your choice
