Ran into this with magtech CBC ammo/brass new

[Guest pfries]

This was the only one of 20 that did it? It was new ammo had a tupperware filled we ran about 100 rounds of it all together only 20 were the CBC head stamp. No noticeable big bang or anything. I did run a sharpie over the split to help it show for the pic.

I get a few like that. Reloading since 91, adding new once fired everytime I go. So, not sure of how old the brass is. I've had new rounds that wouldn't fire, or primer in side ways and just smoke.

CBC is known for having really bad brass. I know 223 regularly has cracks like that. The brass is way too hard and can't stretch so it just cracks.

Let me google that for you

you are right about cbc brass

[Guest pfries]

A lot of people swearing they reload it, these all went in the scrap bucket. I am not taking a chance on it. I was a bit miffed no other signs of over pressure or anything. If this had happened on one of my reloads I would have freaked...

I WAS loading 1k per week, 38spl, never looking at the name on the brass. I was scraping 20 to 100 cases per session. Mostly nickel, 1/4" crack in the neck to full body crack. Load it till you can't. I haven't been to a range in 9 month. All here are indoor and don't want lead boolits.

I wish we had a Stone's river gun range here.

We are talkinga bout CBC brass specifically. Almost any other brand can be loaded multiple times but CBC can't get their initial loads safe.

I pay close attention to nickel cases. Thed reason is nickel can ruin a set of dies if it has a crack or is flaking off. It will scratch and leave a burr on the inside of the die. Once that happens every piece of brass will have a scratch. There is no easy way to fix it either without changing internal dimensions. Same goes for range pick ups that might have sand or dirt on the cases. A stray piece of sand can also ruin dies. This is why I always tumble or wash the cases before they hit the first die.

i used to use range brass pickups but dont any more cause you cant tell how many times its been reloaded unless it has crimped primers

All very good advice. I have some CBC cases [45 Colt] that are stoked up to +p+ levels. I noticed I get cracked necks in about half of them, and they were once fired [by me]. I didn't know of CBC'c craptastic brass at the time. I toss them all. Cracked or not. I have about 30 rounds left. I'm not overly fond of shooting them either. I just buy new Starline cases from Midway or once fired Federal cases if I can find them. I also keep Win brass for easy loads.

Hey Fries, what caliber is this you're dealing with???
