Brass sizing

Re: Brass sizing

With a Full length die setup correctly, all the operations you stated happen in one step. Neck dies only size the neck, FL does body, neck size and bump the shoulder back.
 
Re: Brass sizing

You'll get a better answer if you could provide the caliber you're reloading for, as well as the rifle you're using and what you are planning on doing with it (target/hunting).

For a bolt action, most guys will FL size brass after the first firing in their rifle. Then neck size until it needs to be FL sized (once the brass doesn't fit the chamber).

For a semi, most guys will FL size the brass each time.

This is a generic answer. Specifics will be covered when you provide the details I suggested on top.
 
Re: Brass sizing

Actually, most people here seem to FL size for their bolt guns, as well. Neck sizing is not nearly as popular as it used to be, since most people recognize that they can get the same results with a .001-.002" bump with their FL die.

To the OP, Varmint Slayer is correct. If you FL size, you don't have to neck size, and vice versa. Please get a good reloading manual and read it until you fully understand the how and why of every step.
 
Re: Brass sizing

I FL size every time whether it be for a bolt or semi-auto. If you can properly setup a FL die you will be good to go, and you will know your brass will always chamber.

Scootball,

If you're loading for a gas gun then ALWAYS full-length size. Every time, without exception, ever, for any reason. You'll also need to extend that shoulder bump back to .003"-.004", not the .001" or .002" figure more commonly used for bolt guns. Gas guns are just different animals, and require a very different approach to how the ammunition they're fed is handloaded. Totally different ball game here.

I would very strongly suggest that you simply get another batch of brass, and then <span style="text-decoration: underline">never</span> mix the ammo (or fired cases) between gas gun and bolt gun. If you absolutely must, and cannot avoid using the ammo in both, then load it to function in the gas gun. In other words, JUST load for the gas gun. That ammo will work just fine in a bolt gun. YOu load for the bolt gun, and you'll have problems with that ammo when it's used in the gas gun, guaranteed.
