3" targets at 500 would be great shooting for me honestly.
I'd give it a run with my CTR 223 if I had the chance as well. That rifle just plain makes some stuff easy.
Same here; that's .6MOA & on a good day 1 MOA or maybe a little better is about all I can consistently do.
Add a cross wind & 3" at 500 sure is not a gimme.
My point in my comment was that a round with almost half the wind drift as another is a plus, pure accuracy aside.
But the 6 ARC has some issues too, being sensitive to pressure is one of them & why I don't have one yet.
But it was on the OP's list............
