Yes, I realize what you are saying, and my range that I have shot is under the more picky 1000 and plus. Also I was shooting at large elk.I hang with a few buddies that 2 are world record holding bench@1000, and they have all the tools, Im still picking stuff up, they dont even shoot a antelope unless it is 1000.THE one buddy put 5 rnds in1 3/4 @ 1000 in practice week ago. He is at a match right now. I am very familar with what can be done, shot on local teams as a kid growing up rifle, and on a state champ pistol team. I am not trying to dismiss calculations at all, all for them. Just making a point of being familar with the terrain and game, I have spent so much time in some of my favorite spots that I know a lot of the yardages by heart, to a certain rock , slide, finger ridge, etc. And where I hunt a laser is useless 1/2 the time because of weather, I keep a small photo album, where I road hunt for bears, and have yrd. noted with small sharpie pen on land marks.Nothing flat where I hunt and I APPLY same principals to my archery shots.
