So, for a dose of reality from the bullseye world. They typically don't pay much attention to short line performance, which is how they characterize the 25 yard line. Most of us start thinking in terms of extended range at 25 yards and the cops think that's the end of the earth, if they're an average LEO shooter. So, go back and test this ammo at 50 and find out what it's really doing. You may find a surprise, or not. Obviously, don't mess with that WC ammo. Additionally, take a look at ammo testing protocols done by a guy who goes by Molon on LF, M4C and I think here also. He's way ahead of anything else I've ever seen on any forums.
BTW, that Atlanta Arms ammo is very well known in competitive circles, especially bullseye. I've read that if you stand on the firing line at the Nationals at Camp Perry, you'll see nothing but Atlanta Arms ammo boxes when you look at the top shooters.
