new brass

[goindeep]

i know this has been asked before but i am still confused...new brass lapua .308, i have been neck sizing all my brass for my 5r and up til now it has all been factory once fired. should i load as is and do nothing to the necks, should i neck size the necks and load, or should i blow some non-hunting rounds with a different powder that i dont use anymore to fire form the necks, or should i fl size and load?
thanks

The last new brass I loaded, I just ran them part way up the sizer die so the expander ball cleaned up any dings on the case mouth and that was it. I checked them in a Wilson case gage and they were within spec.

I always full-length resize all factory-new cases I buy for reloading. It's essentially creating the same thing as the "once fired" cases you're used to using from factory ammo. Factory ammo is set to minimum specs to fit all guns, the same as a full-length resized case. Thus once you fire your first loads you can go back to your normal procedure, thus producing the same once-fired brass you've been having success with already.

FL sizing new factory brass will save you some heartache potentially too - occasionally I've caught dings or shoulders further forward than they should be (or further back) although with premium brass I doubt you'll find many.

Hope this helps.

If I understand your question correctly you are firing once fired brass in the SAME rifle. If this is the case I just neck size all my brass until such time it is necessary for them to be trimmed(I'm assuming you know when that is needed). At that time I will trim them, deburr and chamfer them, and full length resize these cases. I always full length resize new brass because I have discovered that the case necks are not always concentric and that many new cases do vary in tolerance. JMHO guys.

+1. Running factory new brass all the way up your FL sizing die doesn't do anything other than open up the neck, since the virgin brass body dimensions are smaller than what a stand FL sizing die produces.

Nosler brass is prepped and well packaged. I didn't have to touch them.

Winchester and Remington brass was loose in a plastic bag. Some of the case mouths were dented, and they weren't prepped as nice as the Nosler.

My Norma brass was really nice, but the Nosler was best prepped to me.

+1 especially with winchester and remington brass i always size them as the case mouths are dented dinged or even almost out of round. just better to do. As for norma, nosler very costly but they make very good stuff. last time i had new norma i micd a few of them. then just loaded them up. Quality from the package was A1

All new brass, no matter who made it, needs to be sized, checked for length, trimmed if required and chamfered and deburred. Chamfered and deburred if the lengths are ok. Mind you, it's best to have 'em all the same length to start with.
Once fired brass that wasn't fired out of your rifle must be full length resized before using it in your rifle. Neck sizing is ok for brass that was fired out of your rifle only.

The Nosler brass, supposedly made my Federal, is completely prepped. It had a chamfer on the mouth etc.
