I'm curious how many of those prefering iron sights and claiming ability to kill game at distance have actually made one shot kills with iron sights past 200 yards
This is the internet. You are one of the unfortunate shooters who apparently shoots more in the real world than here in cyberspace. Groups shot by internet shooters do not strictly correspond to the same group sizes shot by shooters confined to only the real world.
In general, to convert an internet group size to a real world group size, you have to multiply the internet group size by 3, and then add back in the 6" flyer that was conveniently excluded.
Here in the virtual world, we also consider there to be no difference in groups sizes when you compare an offhand shot in the rain at dusk on a moving animal to a rested shot under perfect conditions at a stationary target of known range.
Also, we assume that if you have ever done it once at the range, you will be able to do it every time in the field.
