Thanks for the replies. I'm not worried about blowing anything up, and I will work up with caution. I have 5.56 chambered ARs and wylde chambers. I am just wondering if I can expect the same accuracy results out of thicker 5.56 brass as I could get with .223 brass or if it won't matter at all?
I doubt it will be anything to write home about. The problem is that the brass is junk, and you really need to start out with good cases. But on the otherhand I shot the girl friends AR a couple months ago with a 5.56 chamber in it. The rounds I used were .223 loaded for my 700VS. The rifle shot in the mid sixes with 55 grain Vmax's at 3200fps. The twist rate was 1:10 with a cut rifled heavy barrel. With some trigger work and loads tailored to match the rifle, I think it's a solid half inch rifle.
There is a sampling I took some years ago. Thicker? not by much. The federal match and
federal are the thickest (also softest) and the Lake City military the thinnest. Rumors
abound in this hobby I think.
Yes some military brass is crap, if you buy surplus 5.56 brass get Lake City match or IVI, stay away from WCC, R&P, Wolf, etc... occasionally you can get your hands on a good run of PMC cases, sometimes they are #1 in quality but sometimes they are junk as well.
