If you're not 95% confident in making a cold-bore shot, don't shoot. If you took two hunters and sat them beside each other- one who is taking a shot at 700 yards, but practices weekly out to very long-range, and the other shooting at 200 yards who has been shooting the same box of factory ammo for hunting for the last 3 years, I would put my money on the 700 yard shooter every time.
In the last two years, my hunting buddy's father has shot at, and wounded, several deer within 200 yards. If it were up to me, I would ban him from hunting or else force him to do a bunch of target practice before hitting the fields each year. I practice religiously out to 850 yards, and I've never wounded and lost an animal (ok...I lost a coyote one time). This year I shot my 3 deer at 45, 239, and 264 yards. I fired 3 shots. It pays to be prepared.
The beautiful thing about a long-range shooter/rifle setup (including a scope like this Huskemaw), is that he can turn down the scope to the lowest magnification, and easily make the short shots that some people advocate. The "shorter is better" crowd, however, certainly can't keep up on the longer shots.
