RE: one last reloading question
if you have a bolt rifle that will be firing these rounds and not another gun or multiple guns then you can get away with neck sizing only... resizing the neck of the case, the area that holds the bullet... you never touch the shoulder or further back...
if you are using a lever, auto, pump, etc you MUST full length resize in order to get proper and consistant feeding.. these guns need the extra elbow room to get that round in chamber properly... do not OVER lube.. you'll collapse and dimple the shoulders
neck sizing is "generally" more accurate thatn FL sizing, especially if your chamber happens to be a good bit larger than SAMMI standards for the case dimensions which dies are manufactured to...
you can get more indepth but this is the meat and potatos of it...
