So I joined the case separation club, courtesy of my M14

Neck sizing- make darn sure that rounds chamber freely. If one were to hang up, there is the possibility of an out of battery slamfire.
Separated cases can result from excess headspace. Rare on first firing, much more likely with reloads, particularly if the excess headspace is ignored when resizing. It is entirely possible to work around this. It is not a good idea to just ignore the situation, and assume that retiring brass after a certain number of reloads will be sufficient.
Best to find out exactly what you are dealing with.

Yep, Ask Dogleg how he blew up his Norinco.......If I remember correctly it had fired out of battery because the brass was not fully resized.
 
I am on 5x reloading using various brass for my 07 norinco m14s.
That will be my limit, haven't seen any issues or grooves yet, just my limit for reloads.
As far as neck sizing only that some on here have mentioned, I tried once to feed an empty that was fired from this gun and it got stuck so bad in the chamber I had to hammer down on the rod handle to eject it. I keep the loads to middle of the pack using win primers, 150 gr hornady sp, and imr4895 and haven't had issues in over 1600 rounds so far.
 
This thread should be entitled: "So I joined the case seperation club, courtesy of bad brass."

When I carry out case inspections on multiple fired brass, Winchester brand is the most often earliest discard for myself, closely followed by Federal.
 
well, i DO know that if you stick the case on a scale and weigh it. winchester typically is a full 10 grains LIGHTER than federal, with other brands falling somewhere in between- now if you equate weight with wall thickness, it follows that winchester has thinner walls- however, i 've had federals fail more quickly than win
