Eye relief is so important to consider on a rifle scope when the rifle has the potential to assult your face. I was only 28yrs old. I had one of those day where I felt I had arrived and wanted everybody at the range to think I was really in the know. That I was a serious hunter with my new big bore rifle. I will never forget when I first pulled the trigger on this big bore. It was a hard kicking rifle and the scope cut a half moon right between my eyes so bad that before I put the rifle down I had blood in my eyes and it was streaming off my chin. A lot of things happened in that moment to cause that rifle to jump up and tear my face up. First, I did not hold the rifle in a scure and proper manner. Second, I leaned forward to much with my head while trying to shoot from the bench. Third, I had the rifle postioned on my shoulder wrong. Fourth, the scope was a cheap low line scope. Fifth, I had no idea just how hard a 458 Win Mag with a classic stock and a 500gr bullet would try and beat the shooter to death with one blow. Not only was there blood running down my face and in my eyes, I saw a whole lot of little twinkling stars, and my head felt like it was about to split. Now to add insult to injury, the range master came over with a first-aid kit and was working on my head when he said, "You never shot one of these before have you?" My ego was broken, my pride was telling me to lie to him and make an excuse, but I just said in a defeated hurt way "NO". Of course, he also made me feel lower than a snakes belly by simply saying, "I thought so when I saw that scope you had on your rifle." I said, "what?" Even with my head hurting so bad, he caught my attention when he commented about my scope. I said, "what do you mean when you saw my scope?" He began to teach me about eye relief and I never have forgotten that lesson. I did not shoot another round that day as I picked up my rifle and put it in it's case. I gathered up my other stuff along with my wounded pride and walked off the range never looking around for fear of what I might see in the eyes of the other shooters. Oh, I did ask him what scope he felt would work good and that gave great eye relief and he said, "spend the money and buy a Leupold." That is what is on my ..416WBY Mag and that is all I will ever put on a big bore that tries to kill the shooter as well as the game.
