Odd case seperation....FYI

I reload the 7.62X39 for fun and giggles. While burning up some unknown origin 110 grain bullets last evening a round would not chamber. I was using a very mild load of IMR4198 as usual for this caliber.
It turned out to be a blown case was stuck in the chamber.
The odd thing is the case seperated right at the body shoulder junction. It was a very clean break with just the angled part of the shoulder and the neck still in the chamber.
I used a 3/8" sprial taper tap on the end of a flex drive shaft to "bite" the case neck. A light tap with a brass hammer on the drive shaft bit the case. using a cleaning rod I then pushed on the nose of the tap removing the remains of the case, stuck to the tap.
I've blown several cases before; having one seperate at the point of the shoulder/body junction is a new one for me.
Has anybody else noticed that the chambers of the Russian made SKS's seem to have a Radius junction like the Weatherby cases do. The fired brass shows rounded junctions at the body/shoulder. No other fired rifle cases show this except Weatherby in my experience. My SKS is a 1954 Russian that i bought many years ago.
Oh well; back to the load bench loading more plinking ammo for the SKS.

I haven't had one in any of my 7.62x39's since the Lapua brass cased ammo was common and cheap. The steel cases are a little tougher I guess.
