Case separation on 357 today

[papaboomboom]

Shooting marlin lever in 357 today, had case separation about 1/2 down case, had hechuva time getting it out.
Load was 15.0 grs of 2400, shouldn't be a overly hot load, any thoughts on reason?btw it was first reload on factory brass, thanx for advise

What grain and type of bullet are you using?

[tabascoz28]

I've had case splitting the long way on the first reload. Federal I believe. Same, moderate load of bullseye. Never case head, yet.

Bullet and brass info would definitely help.
Sounds like brittle brass if it split there.

Howd you manage it out? Its happened to me in a sizing die, still there to this day.

Got case out with 50 cal brush after taking bolt out of Marlin lever. Ruin brush but just thankful I got it, took three trys

Make sure the chamber is thoroughly clean - especially if you shoot .38 spl through it. Case separation in a straight-wall pistol cartridge is rather uncommon.

EVENTUALLY.

Sometimes CRAP HAPPENS.

Had the same issue in my 357 Uberti. To make it worse I was cycling fast and next round jammed it in good and no way to get out with brush or dowel. Had to use Cerrosafe to remove. Looking at it after, it was just old brass that finally separated on extraction.

Try Cerrosafe.

First reload on factory brass? That's unusual, to say the least! I've seen vertical splits, like others, but not horizontal, i. e. case head separation.

Just checked Lyman's 49th Edition. They have a Hornady 125gr JHP, same weight as your Speer 125gr. I also use some Fiocchi brass, and it's been generally good for me. The listed loads for .357M and 2400 range from 13.0gr to 17.7gr. So, your loading of 15.0gr doesn't seem out of order at all.

Stuff happens, I guess....

I mentioned in another thread that I had a case split lengthwise after loading it. It would not plunk in my revolver cylinder. Could well have been a Federal, but not certain. Case did not make it to firing, split after being reloaded.
