Thanks to Irish of The Feral Irishman for sending me the link.
Damn, that's a long shot.
I shoot a crappy ol' Bushnell 3x9 on my 22-250 and I can count the times on 1 hand that I've taken it off 3 power. Missed both times, too.
My shots are pretty much limited to 300 yards tops, due to terrain and my own shooting abilities and at 300, the bullet only drops an inch and a quarter with a 200 yard zero, so I can pretty much just hold dead on to that range. Besides, that 22-250 starts to bleed off pretty rapidly after that.
