but they do fall within spec for weight...they are +/- 2 grains (4 grains variance total)

] Duh. Geez, I've been out of it for a while! You are most definitely right. They do say +/-2 grains per dozen. My mistake. [8D]
Just so everyone who reads this thread knows that the Epics are advertised
4 grains (+/-2) across a dozen, and the ACC's are advertised
1 grain (+/-0.5).
I mistated those specs in my first post. 
In my case, both sets of shafts met their weight specs!
I do take a "bore weazel" and some barrel patches and run them down the inside of the shafts. Some people would be surprised at how much crap comes out on that patch!
You can never be too anal about your arrow shafts.....
