If you're SATISFIED with the accuracy of Wolf or Q3131A, you go right ahead and buy that stuff.
I'm the sort of guy who gets pissed if any one of a ten round string so much as TOUCHES the 10 ring at 100 yards, though. I like only X's, and overlapping ones at that. That's why I'm committed to loading my own .223, and I'm paying about as much for a thousand rounds of it as you pay for your Q3131A, yet I'm getting half inch groups (or better) vs. your two inch groups.
Accuracy is of utmost importance to me. If I can get match grade accuracy and pay no more per round than buying the cheap stuff, suddenly it's a no brainer. Reload!!!!
At 100 yards with a 4X scope, I have to move the crosshairs off the point of aim to see the group I just fired. Means I need a scope with a finer crosshair!
Now, THAT'S what I'm talking about!
