re: Reloaders, help!

If you plan on taking the rifle to the field where it can get dirty, go with the full size.

A neck die only sizes the necks. So as the brass expands it forms to your chamber and the shrinks back a bit but is still formed to that chamber. Benchrest shooters neck soze because they get more consistent velocities.

If you are using this brass in a couple different rifles and taking it to the field id get a full size die. I'd probably just get a full size die anyway, just to avoid the issue of brass possibly not fitting or being hard to chamber.
