Wow! That's a ridiculously low prices for that ammo. I've had pretty good luck in the past with SSA ammo, so I think I might have to stock up on a bit of that myself. Thanks for posting. QQ - as long as you test a few different brands and find something your rifle "likes", you'll be fine. If you have access to a chronograph, I'd use velocity extreme spread as one of the readouts. In my hands, even the best commercial .223 Rem ammunition can suffer from excessively high ES/SD. So if you find a couple brands that show good precision, you might be able to whittle the list down further using velocity data as a readout. Good luck with it.
