I have a 7.62 Enfield No 4 target rifle which I have scoped , after sitting in the cabinet for several years waiting to be set up and refurbished this was the year to finaly get it back on the range or so I thought .
The first trip out The retaining screw on the no gun smithing scope mount came loose and I managed to strip it by overtightening it as it was a brass screw .
Second time out I must have picked up a tiny bit of grit on a cartridge when I closed the bolt it jammed tight a few mil out of the breach , so the bolt wouldnt open or close and needed a lot of force to get the bolt open then force the case out of the chamber with a rod .
Then today after sixty rounds or so a case separation , it was a Lapua case with 44 grains of N140 and 168 grain bullet . I went home thinking it would be a hard job trying to the rest of the case out of the chamber , after removing the bolt I slid in a length of thin stiff wire with a hook on the end just to have a feel , low and behold as I pulled the wire back it clicked onto the neck of the case and out it came , with no resistance .
One saving grace no hassle , having about a 100 rounds left with a couple of different loads as I have been trying to use up the odds and ends as it was only an ETR shoot , Iam thinking off pulling them all and inspect all the cases I have and trying a lighter load . Must admit the shoulder was begining to ache this morning .

Well thats FB finished for this year , roll on 2013 .

How many times fired were the cases, how many times FL resized and were they ever annealed?

That is a 64 million dollar question , as I got them from a friend who was giving up FB , he is a very meticulous shooter so I wouldnt think he would pass on anything he thought wasnt up to the mark .
But its the first time I had used them .

Check the other cases for the dreaded 'shiney ring' syndrone. If in doubt - chuck 'em out,
Time to suggest a Christmas wish,100 lapua cases please Santa.

Just gave them a couple of hours in the tumbler and checked found a few that looked as though they might go soon so binned them , got plent more in the cupboard I can use .

Did you piano wire the inside or just look for bright rings on the outside?

No never heard of that before , so I tried a bit of stiff wire down the inside felt a jump in one of them that I had left , dumped them now just to be safe .

Yep, that is the best way of checking for incipient case head separation, a length of piano or stiff wire with the end bent up at right angle short enough to enter the case. Draw this up along the inside of the case from the botton and you will feel the groove forming when separation is imminent.

The shiny ring on the base is misleading as this can often come about from the sizing of the case and is not a good indicator.

Such wisdom. We wouldn't have thought to do that !

Hi Badger, that little trick has been around for a long time, I was taught that one by an old shooting hand when I first got into to reloading, back when the Earth was still young.
