.303 British Brass question?
- Thread starter TrxR
- Start date
Its new Factory ammo.
Lee Enfield No1mkIII.
Here the rifle in question. Any reason to quit using it for hunting? It seems plenty accurate enough for dropping deer, Ive put three in the same hole a 50yds. I was thinking about reloading for it but I don't think its worth it as I wouldn't go through more than 5 -10 rounds a year through it.

Im referring to the expansion ring. The diagonal line is just a scratch from handling. The expansion ring seem more defined by feel on one side than the other.

I believe that you will sometimes get that 'look' from a cartridge that is fired in a 303Br. having a slightly 'generous' sized chamber. The case expands to fill the chamber when fired but the base, basically being solid, does not. Usually a sign of the beginning stages of case separation is a bright very noticeable line around the circumference of the case, and at the top of where the base is attached to the main body of the case.
I found this animation a while ago which seems to explain it:
You can do "the o-ring trick" which is just to slide an o-ring over the case above the rim so the case head is pressed against the bolt face. Doing this will cause all expansion to be forward and if you do it once or twice per case and only neck size they will headspace off the shoulder instead of the rim (which it can't do properly in a loose military chamber).
Sometimes I get uneven case head stretching and get what is often referred to as a "banana case" where the case is actually slightly bent.
It may be worthwhile to invest the $10 or so in a broken case extractor for 303. It wont help you with a follow up shot but it will prevent the rifle from being disabled for the rest of the hunt.

The primer is protruding a bit but for some reason I think they were before fired.

The one I have now gets used for a little off hand shooting every once in a while. I picked it because it was in better shape than any of the other three previous Jungle Carbines I've had plus, the suitable extras that I have with it.
With changing out the bolt head to one of a more appropriate size to minimize the head space, plus just neck sizing the cases for my reloads, I get decent case life with the 'old girl'.
