    I am reading my books before i buy my kit. I saw something that surprized me.

    1st question: The book said something about if you shoot some ammo through your gun then reload it you can only shoot it through the same gun. My thoughts where because of the expansion of the cartridge maybe being different in other guns but if you resize it why would that matter. Any advice

    2nd question: Does that (above) rule still ring true in a 45-70 case since it doesnt have a neck and looks more like a big pistol round?

    Thanks again for all your help!

    You read correctly, just a little misunderstanding. If you NECK size only, then that round is just for the rifle that it was fire formed in. If you full length resize, you're "going back to factory spec" and the subsequent reload can be fired in any appropriate chamber at that point.

    45-70, you'll be full length resizing so it can be fired in any 45-70 chamber.

    +1 woolley worm, dead on the money. Make sure your using a good lubricant when you full length size, otherwise you will be having issues. Neck sizing does not need lubricant with the Lee collet die.

    Also from what I have been reading they are saying that if you are shooting out of a semi-auto that you should be using a full length resizing die. The bolt action is ok in using the neck sizing die if it is the same rifle.

    That is correct. I think you'll find 100% majority here that full length resize for their AR's.
