Anything like Amerc is junk an would toss without question. Also look out for berdan primed I've managed to find some and bent one decapping pin from it.

Amerc per above, alumninum blazer, berdan primed, be careful and weed out 9x18 MAK cases. Cases with a Nato cross might have crimped primer pockets, recycle them if you're too lazy to decrimp them.

Sorry to jump on the OP's post, but I have a question that goes sort-of along with this post...

I also just got in 2k of 9mm mixed Brass and I have a bunch of S&B, which I have read had really tight primer pockets (Atleast in .223), Are these a problem in 9mm?

They all have red primer sealer if that makes any difference.

Thanks,

Any S&B handgun casings I have found to be really tight...still reloaded them though. Can't say on rifle casings..

Never had a problem with 9mm S&B. I have taken to cleaning cases first in walnut, then decap/resize, then polish in treated corncob which thoroughly cleans and polishes the primer pocket. Them primers glide in like butter!

I assume swaging and/or primer pocket uniforming would fix the tight primer pocket?

S&B 9mm brass work well for me and I find thier brass to be some of the best I've used. Using WSP's I have not had a problem. Primers seated with relative ease but not loose.

Anyone happen to know the headstamp R-P? While not in 9mm I have to sort and scrap all this brass because for some reason it will not hold a seat with my .45acp. The projectiles just push through while on every other headstamp this is not an issue. Didn't want to make a new thread so I just posted here, hope that is ok

RP is remington brass. The only thing I've ever noticed with this brass in 9mm is that it is shorter than most other brands.

Have you tried belling the case mouths a little less w/ the RP brass?

I reload lots of 9mm. Amerc doesn't work well for .45, but in 9mm, they work just like they should.

The only ones I discard are the ones that still seem difficult to seat after reaming the primer pocket.

I honestly just didn't want to adjust everything just for one particular headstamp then adjust back. I will just have to pull the projectiles and throw that brand in the scrap pile

CBC is the type of brass used in magtech ammo. I think it works fine. The only stuff not to reload is the aluminum stuff or berdan primed. Some of the steel stuff can even be loaded if things were to get bad enough. Unless a case is split more than 1/3 the way to the case head, it will shoot accurately enough for bullseye purposes.

I will load almost anything. In doing so, I have learned a lot. As always, start low, and work up safely.

It works but won't pass through a case gauge.

I always know when I've let a CBC case slip into my 9mm brass when it goes through the Lee FCD. WAY more resistance than other 9mm cases. After the FCD it will fit into my case gauge. If it doesn't go through the FCD, you're right, it won't fit in the case gauge the majority of the time.

I find CBC and S&B brass loads fine in 9mm. Primer pockets are a little tight with CCI 500 primers but seat ok. As far as RP Remington brass, it does seem to have either a little softer or a little thinner brass at the case mouth especially with some lots of .45ACP. For anyone with brass that their sizing die won't reduce the neck enough for proper bullet tension in the case, I recommend the EGW Lee U-die. (Lee undersized die) It's made a thousandth or two smaller than regular sizing dies and will size cases down enough that bullet tension is tight. It also sizes down a little farther on the case than standard carbide sizing dies and will remove any bulges in pistol brass. Some pistol sizing dies seem to be on the large side of specs and any brass that's a little thinner won't hold bullets tight enough for some brass I've loaded. I bought a EGW undersize die for .45ACP and like it.

Beat me to it.

And for the record, I love S&B brass. Very strong, good stuff. Tight primer pockets, but not overly so.

Remington primer pockets tend to have a "generously" rounded lip. I've found them very easy to seat primers in, especially when compared to uncripmed Winchester brass. I hadn't noticed a length issue with them. They load and shoot just fine for me.

I avoid:
A-Merc
Nato/Military (crimped)
Berdan
Non brass/nickel

Really every other brand of 9mm loads and shoots fine for me.

The Chinese CY headstamped cases of mine got loose primer pockets after a few loadings....not sure how common these cases are nowadays.

You know last night I was loading up 100 rounds for an IDPA match and the brass was in a baggy that I thought I had sorted to only be Independence brand.

I was loading on my 650 and everything was smooth and then I felt more resistance when resizing.

I checked that loaded round when it popped out and it was a S&B case.

It's funny how some cases just feel different when loading.

Another brand to toss: Chi-com LY (Norinco)

Identifiers:

12 O' clock: 9 x 19

3 O'clock: Y

6 O'clock: ES

9 O'clock: L

A round reloaded with this case had a case bulge beyond resizing. Also the primer wouldn't seat.

According to someone who knows, LY brass is signiifcantly softer than most other brass.

I've only ever seen "CJ" Norinco brass; it seems "cheap" though I can't quantify that. What I've seen comes loaded with bullets whose jackets are exactly the same color as the case. I'll keep my eyes open for LY...and it goes into the recycle bin before anything else!
