Sorry guys, I won't be joining the long range spotting-shooting club. As I said before, I'm fine punching holes in paper as far out as I can, but I've never been forced to shoot big game at more than 300 yards and therefore concentrate my practice at shorter ranges. You can do what you want.
That's pretty much the same bottom line that I had when we all went round and round on this subject a while back. If you are taking shots from 700 yards because you can't get any closer then you suck as a hunter. If you are hanging back at these distances on purpose just to see if you can still hit something then you are just playing Rambo Sniper and not actually even trying to hunt the animal.
Is a 750 yard shot an impressive feat of marksmanship? Yep, but I'd be just as impressed to see you hit a gong or a milk jug at that distance. Making your "target" a live deer at that distance adds absolutely no extra element of impressiveness. And so far as I know, no one has ever wounded and lost a gong or a milk jug.
You are wasting your talent on hunting, you should be shooting in the National Matches or perhaps on the Palma team..
I know. Ain't the internet grand. People can do dang near anything. On the internet that is.
