While going through about 1500 pieces of mixed 45acp brass I noticed that the CCI and *I* brass has flash holes noticably larger than any of the other brass, but the primer pocket otherwise looks the same. I was just wondering if that has any practical meaning for loading purposes? Will it change burn characteristics enough to warrant changes?

The 1/8" flash hole cases are from "lead-free" ammo.
The reason is to lower the primer pocket pressure with the more powerful leadfree primer mix. Otherwise, the primers back out and can cause gun damage.
I doubt it would matter but I would keep & load them seperate from the other standard cases.

i noticed that last night on my mixed 45 brass. Never noticed it before and have been loading them all the same with the results being more accurate than i am.

This has been covered many times on this, and other, forums. The bottom line is: reload them and shoot as normal.
Hope this helps.

Thanks guys ... sorry for being such a n00b :neener:
One other thing I noticed, the insides of all the "large flash hole" cases was significantly cleaner than any of the other cases. Just an interesting observation that I have no idea what it means, haha.

It means they were clean burning, smoke free, sootless, indoor range safe, not to kill the children from the fumes, or cause hideous birth defects, lead-free ammo, with large flash holes.
