Re: 223 brass shrinking?
Are you sure about the trim dimension? What did you use to trim with? Did you measure after trimming? Most of the times I have seen cases shrink is the first time firing to fire form new brass to a specific chamber.

Re: 223 brass shrinking?
Yes im sure,used a L.E. Wilson trimmer,checked after trimming, this is the first time Ive seen the brass shrink it always grows a little after firing,used the same powder charge,primer and bullet the only thing that was different was the outside temp was in the low 40s

Re: 223 brass shrinking?
The outside temperature may have something to do with it. But like I said above, I've not seen this before.

Re: 223 brass shrinking?
M855,
My Lapua .223 and .243 quit growing after 5-10 firings, but this was in fairly tight chambered rifles. Even after annealing, they didn't grow any more. I cannot give a reason, just letting you know what happened.
