weird 9mm brass..warning

[vonzep]

I ordered a batch of roll sized brass from a member. Good deal, fair price.

I am pretty meticulous and weigh my brass and visually inspect. We'll this one I somehow missed on the visual inspection but caught on the weight. It has a double wall With a much reduced case capacity. Has anyone seen this?

I have seen those a couple of times. Since they are so obviously different than most, I pitched them. I never found enough of them to amount to anything.

Ammoload brass! It's been around for a while. Personally, I'd toss it out of concern for the potentially reduced capacity. I once saw a post from a guy who claimed it was the answer to a Glock owners dream.

I wouldn't go that far. I've seen sectioned cases, they were definitely made that way on purpose. 9mm cases are thick at the web anyway. This could simply be a communications issue between R&D and production. I suppose you could try sizing the case and comparing its capacity with a more normal commercial case.

They're made that way on purpose to prevent bullet setback. Federal and Blazer .380 brass have been made that way for several years, but the step isn't quite as pronounced in the .380. The first 9x19 cases I saw made with the step were AmmoLoad brass. Since manufacturers don't make their brass for reloaders, with the exception of Starline, Top Brass and a couple of others, they can make it any way they want to suit their needs. From their point of view, it's an ingenious way to prevent setback, but a pain for reloaders.

Hope this helps.

I thought it was for extra support in pistols that have a unsupported part of the chamber, like a Glock.

I visit 3 reloading forums on a regular basis.

The general consences on one very high traffic forum was "I reload them all the time they work just fine".

Of course I would start at the start load and work up.

OP, if you want I may be able to direct you to the thread.

Thanks. I'll keep my eye out. Just what we need more junk brass.

I'm running 5.3gr of be86 behind a bayou bullets 124 tc. So to test this out I started at 4 gr of it and was fine. At 4.6 gr had primer flattening. Hate to see what a normal load would do atv5.3 or a hot load of 5.8.

It pays to check the brass

Been around for some time now, the set back reply was the correct answer.

From info ive read, these have appr 10 percent less case capacity than normal brass. I had appr 60 of those from a 1k brass order. I use em for making boolit stands for pc'ing.

And people make fun of me for sticking with my stockpile of win govt 9mm brass. Never seen ammo with a step like that ... set back issue makes sense but there isn't that much room in a 9mm case as it is.

I pitch those into the recycle box for the next scrapper trip.

If there aren't a ton of them, I would just throw them all away. If you had a ton of them, I'm sure it would be fine if you knocked the usual load down .2 grains or so and checked to see how it responded.

I use them with starting loads. No issues.
