.44 mag split case

[jc2cdo]

I recently picked up a new Ruger 77/44. I have fired 11 rounds of Winchester 240 gr jacketed soft point through it. I reload for all of my other calibres so I saved the brass. Once I got home and had a look at the brass, I noticed that one case was split from body to mouth, about 5/8 in long.

I've mic'd the unfired rounds and they avereged .452, mouth, body and web

I also mic'd some unfired AE rounds , they averaged .451

I have some unfired Win brass that mic'd at .452

The fired Win brass mic'd .455 mouth, .457 body and .452 web

The split case mic'd .456 mouth, .458 body and .452 web

So WTF? Weak brass? Over sized Chamber?

Anyone else having problems?

I just measured some brass that was fired in my Ruger Redhawk revolver. These were loaded with full power loads, so comparable to factory ammo. I got:

0.456" mouth
0.457" body
0.452" web

So, pretty much the same as your results. I would say you got one piece of bad brass, your numbers don't seem to indicate a grossly oversized chamber. I mostly load softer .44 special level loads and still have the occasional piece split, it is just a fact of life that some aren't going to make it.

Thanks Mark

I thought it might be just one bad case but wanted to compare with someone else.

Thanks again
