So I am not a savvy marksmen shooter, Last year 3rd season in colorado I had a opportunity to harvest a really nice buck what seemed to be 5x5 through the lens of my 10x42 bushnell bear grylls binocs. He was uphill about 275, basing off my golf expertise as I did not have a range finder. So I set up on get my sights on him pull and was unsuccessful, barrel pointed above vitals; maybe a 1/2 inch above pull the trigger and he stands their as if nothing happened shot a 2nd time and he ran off. Hike up hill to no find no blood but see him down hill in thick oak brush about 200 yrds down, setup again this time using my backpack as a stand and point above him again and shoot miss 2 times and see him run off to my dismay... basically i shot 4 times and was a complete failure any info on shooting up and down hill will be invaluable to me and much much appreciated..
