Jdscholar,
The last time I shot long range (by my definition) was at 410 yards. It was only 3 shots, which isn't really a justifiable "group" but it was right at 3 inches. A few weeks later, I shot 290 yards. The group was odd, also right at 3" but it was almost PERFECTLY horizontal. There was less than .2 inches vertical spread.
Technically, I would have missed the ball on one of those shots by like .06 inches.
I know what you're saying, real conditions are humbling more often than Internet claims would have us imagine but 300 yards isn't all that far, particularly since I specified "under IDEAL conditions".
My gun is a Ruger M77 MkII, chambered in .204 Ruger, with a 13oz Jard trigger, topped with a Mueller 8.5-25x50 scope. I load my own ammo and routinely hit woodchucks in the head at distances up to 300 yards, and rarely farther, for lack of available distance, not for missing.
Thing is, my gun and equipment are cheap and very average and my abilities are slightly above average, at best, certainly nothing special. Being that there are guys here on TFL with the equipment, time, ranges and ability that FAR exceed mine, I was truly expecting a few guys to claim distances approaching 1,000 yards. I'm certain there are a few who could do it.
