What scope magnification do you guys use for "sub-MOA" groups? Or, for that matter, any sized group at range, not necessarily one under an inch. I ask this question because I see people saying (and posting) things like, "yeah, I can get a such-and-such MOA group with my uberboomersmack at 100 yards", but no mention of what their sighting mechanism is, or the position they shot from.
Basically, I'm trying to figure out if I'm a good shot.
I went out shooting the other day with a buddy, and we plinked with a variety of stuff, but then walked a box out to 100 yards with some stickers on it. My rifle is a RRA AR15 16" and has a 4x30 Leapers cheap-o scope on it with a built in BDC I've never bothered to use. I just have the rifle sighted to 100 yards, and that's as far as I've ever shot it. I shot it prone, 5 shots per target. There was about a 10 mph wind coming from 10:30, gusting up around 20mph, and all of these shots were taken prone at 100 yards w/ Fiocchi 55gr FMJ.
The first, larger target was actually my sighting in group because I'd not sighted in the scope before on this rifle, aside from the last time I was out when I just made a rough group (I adjusted the scope between visits, and it my first adjustment was spot on). Each target had 5 shots taken at it. But, aside from the 1st target, which I shot at fairly quickly, the smaller dots were impossible to see and posed a real problem, being so close together they were difficult to distinguish at all as much more than "there are some orange specks thataway". They were just too darn small, and the crosshairs in the scope itself obscured the target dots, requiring me to aim above and to the left to try and find the target (and I believe its evident that I did so if you look at the photo).
So what is everyone using while shooting at 100 yards and claiming such-and-such groups? Is this 'reasonable' performance on my part? I can't see how someone might group like this using (say) a red dot or iron sights at this range (or beyond) for anything short of "general cover fire" because it's unfathomable to me that someone could actually see their target at such range with enough clarity in relation to their sights to make such a shot. Again, especially with iron sights.
If I'm right, and tight groups can't be expected with irons, what kind of groups might a good marksman be able to expect out of a rifle like mine (16" RRA AR) using standard aperture sights?
