It is appairent that one of you can shoot, however I would like to see that off hand stint with the M1 Grand. That is impressive and alot better then I could ever do, why not a National Match M1A? I am not picking on you just curious.
Now to the long range needle blowers. Have you ever looked at your down range energy, I doubt it. Think of the time of flight of your bullet, rumor has it a deer can run 30 miles an hour(I would like to see that) this is 44 fps. You fire and the deer moves you got a missed or wounded deer. The target shooter that was posting a while back, I will bet he can tell you time of flight, drop and remaining energy at any range he shoots and I get the idea he will not take super long shots.
I supose if you smell bad or do not know how to hunt you have to take those 500 yard shots. Either that or it is an ego problem after all we are shooting at a living animal and we want a quick and humain kill not a maby. Hunting is not target shooting. We have a responsibility to the sport of hunting and the game we hunt to be ethical. This super long range stuff is like driving a Lamborgini down the highway at 180 mph, It can be done but it is not tha actions of a reasonably, responsible person!!
