    Will neck size only reloads cycle in a semi auto?

    Hey Dave we could use more information. Calibre, weapon,and process you are using. Was ammo fired from the weapon you are reloading for?
    Love to help just need more info.

    Thanks and sorry I left out the peculiars. The gun is a bushmaster ar15 vmatch heavy barrel yada yada yada.
    the brass was fired through this gun. My thought "Full length sizing defeats half the purpose of reloading. So why not just neck size and then put a crimp on there to prevent any bullet movement". 223. Thanks

    I think you are on the correct trail. If the brass comes from the gun you are loading for; full length resizing should not be required. It will just over work the brass. If in doubt..load a few and give it a try.

    Absolutely, welcome.

    The only problem you might encounter is the action failing to close fully when the rifle is dirty or after long strings of fire. The semi-autos dont have the leverage of the bolt action to cam into battery on max-size cases.

    Neck sizing is generally believed to be most valuable in prolonging brass life, and improved accuracy associated with, (for a large part) bolt rifles. You will encounter some locking problems with neck sizing only on practically any auto loader. Further, the extraction of autoloaders will generally damage, or lose the brass before the extra metal working of full length sizing will destroy the brass. Auto loaders being more modern are usually in calibers that aren't that hard to acquire if they are damaged, whereas with some of the older bolt rifles, the brass is like gold, and must be cherished.

    Thanks for all your replies. I think Maybe I've been led astray. It was my understanding that "Fireformed brass is part of the reloading advantage" and full length sizing would take that advantage away. Granted it is a pain when those dang things fling brass 10 feet away. I enjoy scrounging around for a 3 cent case.

    That's absolutely correct, but the benefit there is with bolt-actions. If you neck-size only on the semi-autos you're going to get a lot of failures to go into battery.

    Well hell, I'm glad I found out about this before I made a few hundred rounds.
    Doc I wish you were my neighbor, I've been seeing your post for about a year, and is there anything you don't know?
