Home Forums Reloading Big Game Rifles Sizing new brass

I pulled out a box of Nosler brass I’ve had on hand for a few years. Given that it’s touted as weight sorted and fully prepped I was hopeful I could open the box and go straight to priming. No such luck. Several were noticeably out round at the mouth like the one pictured. My first time using out-of-the box Nosler brass.

Neck size it

I’m a big fan of nosler brass. Very consistent brass. I had a few with bent necks in my lot. I just used a bullet backwards to try and get it back to close. I like to fire form all my brass so wasn’t going for accurate. I’ve found that I found pressure about 1 full grain sooner than with my federal of win brass. After a few firings more like .5 grain less in nosler brass. Good luck

Sometimes even the good stuff gets bent.

I just run them in the die to clean up the necks then load.

I always run new brass thru the neck sizer. It is just another step towards making good reloads.

^^^^^^

I run all new brass though my expander mandrel and it takes care of the sings 99.9% of the time.

Yep neck size it

Round out necks and dont touch shoulders

I had some new Nosler brass that was supposely prepped and ready to load.It wouldn't even chamber in my rifle.I ended up full length resizing the brass and it chambered fine after that.

Run it through an expander mandrel. No reason to neck size.

I resize all new brass. The die seldom touches the shoulder but sizing uniforms the case neck and straightens out any dings and dents.

I'd seat a bullet and go shoot.

I use Lee Collet dies on new brass. Even range brass gets the same but do check function before loading.

Just loaded up some Peterson .260 Rem brass. Didn't do a darn thing but seat bullets. Of course, it comes in plastic box with foam padding to keep things from rattling around. The ones I checked had 0.001" neck runout and all produced 0.004" neck tension.

If you buy new brass in a plastic bag, then you get some extra work.
