Objects of the most stupendous magnitude, and measure in which the lives and liberties of millions yet unborn are intimately interested, are now before us. We are in the very midst of a revolution the most complete, unexpected and remarkable of any in the history of nations.
So there than the broken shell extractor what did you use?
I've had good luck putting metal parts in the freezer when I've had issues.
I have a 16" DPMS SS Bull Barrel. My barrel is marked .223 NOT 5.56. I mention this because I have double checked my chamber with Ned's gauge from Michiguns. It is truly a .223 chamber. I also have Ned's reamer but have purposely kept this chamber .223 instead of "fixing" it. Just be careful not to put 5.56 ammo in it. Perhaps this is what might have happened?
Markm, I was under the impression that when your cases start being hard to chamber in an AR, bumping the should back .003"-.005" was the correct amount to bump for reliable chambering. From what I hear, this doesn't need to be done till the 4th or 5th loading.
Does this sound correct?

I have an RCBS 223 case gauge. I shoot a box of factory m193 or 885 through the rifle and measure the cases. For example my main rifle is +.004. When I reload for that rifle I set up the FL sizer for +.002 and bump the shoulder back .001-2 based on how many firings on the brass. As the case work hardens, I find the bump gets less about the fourth reload. If you get erratic bump back on new brass use more lube.
On 4-5 reloads I only bump the shoulder back a total of .008 -.010 instead of .020 which saves alittle on trimming and I generally load 24.5 of TAC with a 55 for blasting ammo so I generally only have to trim once after initial sizing for 4 reloads.
ETA:
My SCAR has a 7.62 x 51 chamber whi h is reportedly .005 longer to the shoulder than a 308 Win which sounds about right since cases come out on a 308 gauge @ +.007. I FL size them to +.005.
Factory new brass for 223 and 308 generally run SAAMI -.004 so my scar brass is growing .011 the first firing. Food for thought.
