Do you full size when loading for autoloaders?

[Nessal]

I always fully resize my brass when loading for my autoloaders but recently I was thinking of maybe just doing neck sizing to help extend brass life. Has anyone had any issues just neck sizing for autoloader?

Always full length size for auto's or you could get a live round jammed inside your chamber.

Only neck size for bolt actions and only use the same neck sized brass in the original gun it was shot out of.

i have a small base die set that hasnt failed me yet- i wouldnt get one though unless you need it...

If you don't FL size, you will induce premature wear to the locking surfaces by forcing them to wedge together everytime the bolt closes.

Rule of Reloading #58583940: ALWAYS full length size for Autoloaders, no exceptions.

I always do! Removes case belling. Try not resizing one and place it on a case gauge. I bet the shell will not fit.

I always full lenght size for semi-auto. If you have any match chambers with close tolerances, you can really get one jammed in there if you don't, risking damage to the chamber. I also check for length and trim any that are long after resizing. For accuracy semi-auto rounds I hand pick them and make sure all dimensions are uniform. It adds some steps and work, but pays back in accuracy.
