The reason I think long range shooting is too risky is the wind factor. One can't be sure of how wind will effect the bullet somewhere along it's 800, 900 or more yard path to the deer. One can only make guesstimates, which in many cases won't be very accurate. Even slight breezes at that range can move the bullet enough to get you a gut shot deer. I really wonder how effective this type of shooting can be. Yeah, they will show the videos of themselves dropping an animal a long ways off, but how many did they miss or wound before they got that one spectacular shot?? That they surely won't tell you!
