What process do you do with new brass?

[MarikinaMan]

I just received my first order of new brass. I have always reloaded once fired factory and range pick ups.

I bought new brass to see if it affects my accuracy.

What do you do with these?

If its long or inconsistent, I will trim it.

If it passes a case gauge, I'll leave it at that.

I do expect to uniform the neck size (my terminology may be off herea)

But do you anneal? Is there a need to? Do you uniform the primer pockets? Do you resize just because? Do u true the neck?

I am no expert, but from what I've read, New brass doesn't need to be annealed, so I don't. I use a carbide neck expanding mandrel, check for deformities, sometimes weigh cases, uniform flash holes and primer pockets, chamfer and debur, and then load.

New brass will probably be fine but I still suggest you pick a sample of 5 or so at random and make sure they chamber in your rifle. I had to resize 500 once-fired cases that were supposed to be ready to load but would not chamber in my Tikka in .243.

cool. thanks.

I run them into my die enough to take out any deformities in the neck and uniform them. I deburr the flash holes(especially win brass) and hand prime. I chamfer the inside of the neck so it does not shave bullets---especially all copper ones

But do you anneal?

When I am lubing and full length sizing new brass, I will occasionally drop one (or two).
If that happens, anneal down and pick them up.

Quality brass should come out of the bag/box the correct length, wouldn't hurt to check a few just to be sure.

Rule of thumb (or is it wrist?), consider annealing after five loading's is what I recall. Opinions differ I'm sure.

I neck size and clean up the case mouth, thats all you really need with Lapua.

I got a box of Starline brass a while back which came with an insert that said to either run it over the expander ball and chamfer/deburr the case mouth, or tumble then chamfer/deburr; both just to get rid of the factory lube in the case mouth.

Maybe I missed it but was your inquiry on pistol or rifle. If pistol just load. I don't anneal new rifle brass or trim first loading either.

[MarikinaMan]

rifle, and opening the box, Starline had an insert saying what to do. pretty cool.

Every box of Lapua I have ever bought, I went ahead and full length sized them. It turned out I needn't have bothered, they were all perfect. Amazingly well made brass.

Its pretty darn good. Some of my Ackley Improved brass has at least 20 firings. Primer pockets are still tight.

[MarikinaMan]

I took a sample of 10 from a case of 250 Starline 5.56 brass.

Case length varied from 1.746 to 1.752. Kinda disappointed. I can’t trim the short ones, and the variance is worse than when I process once fired.

I gotta figure out what to do here.

[kevins750]

are you shooting this brass in a bolt or semi?

all my new brass is either lapua or norma, just a mandrel through the neck and load for me.

['ol shooter]

I would load the shorter ones as normal and shoot them. They will stretch some with every firing.

I bought a bunch of once fired Win. .223 police range brass and some were not hitting the trimmer that was set at close to minimum length after sizing. They obviously functioned in the rifles.
