Greetings,

This is a Lake city .223. I do not know how many times it has been shot. It is a range random pickup.

Question: Is it not a little bit high for the stretch ring???? I though it woul dbe lower than that.

Thank you
 
Not unusual to be up that high.

If you look closely, you will see it is exactly where the thick web ends and the thin sidewall begins. ;)

Aren't you glad you checked? :)
 
Greetings,

You are totally right. The thick ends and the thin begins.
Now, I need to find one with the "grit" inside and see what it looks like.

Thank you
 
Kestak - I've heard that you can feel the stretch ring by straightening out a paper clip, and bending the very tip at a right angle. Insert it all the way into the case from the mouth, and use it as a feeler probe by dragging it along the inside of the case back toward the mouth. Can your feel that ring using this method?

Great post. I thought it would be more toward the case head also, but with your picture, it makes more sense to me now. I've a better idea what to look for. THANKS

Greetings,

IT is exactly the way I found that ring. I do that with all my cases. :D

Thank you
 
That's great to know, Kestak, and good on ya' for checking your cases like that! This is a very educational post. THANKS!! :cool:

That is the usual place a case separates when shot in an AR 15. For a bolt gun, it separates at the web.
In the past, I've had quite a few case separations in the AR and they've ALL been 3/4" high on the case.
The same applies for the M1 Garand. I think it has to do with the pressure curve and the taper of the case.

Its not a case seperation is it?? Its a stretch mark. If shoot out of the same gun neck size only and you will get more life out of your cases. If your not happy with that put a new barrel on it.

No, but it's darn close too it.
The case has reached it's useful life, and no amount of future neck sizing is gonna change that.

Probably from shooting cases like the one Kestak posted just one more time.

Some folks shoot them until they see a shiny ring or they actually separate, but I am in the "check em first and scrap em when you feel the groove" camp. :)

But RC, it IS a case separation, that's where it happens in the AR, and, yes, from too many reloadings with the size die set up wrong.

can I perform neck sizing only with a fl resizing die ?

No, but you can partially full length size your cases. Screw the sizer down a tiny bit at a time until your cases chamber easily, then quit. Case life will be much better.
 
Greetings,

It will not separate. I decided not to use THAT CASE anymore. :neener:

Thank you
