So I did some trading and picked up a used New England Firearms .22 Mag.

I took it out tonight and on the first fired round the case failed to eject. I figured that this was the reason the guy got rid of the rifle.

Pulling the case out with some needle nose pliers, I noticed that the case was pretty tight in the chamber. After inspecting it, I noticed that it was split from neck to base.

"Not good" I thought to myself.

Firing another round no problems with ejection, the group was starting off good.

Round three, flier and stuck split case.

All in all, 7 out of 26 round split.

Now the ammo, not sure of the specifics, I got them in a baggie with the rifle, Winchester HP is all I can tell you.

There were a few FN Winchesters and CCI Solids, I had no problems with.

The only thing that I can figure is the possible storage issues (exposed to Low/High temperatures) on the previous owners end?

Let me know what you think...
