[QUOTE="MudRunner2005, post: 1420465, member: 12995"] You are correct. Your buddy needs to learn basic rifle mechanics before shooting LR at live animals. He needs to stick to steel while he learns the basics of LR shooting. An easy way to prove you're right, is to teach him how to manually configured a proper drop-chart using all those crucially needed measurements. Because if you're measurements are not right, then your drops won't be right. And this will be easily proved on the range when he's shooting over or under his target, despite what his chart says. Also, right-hand twist barrels (most all barrels) will cause some slight bullet drift to the right over dead-center, even at 100 yards. So a "dead-center" scope, is only good if you're 110% positive your action is 100% square to your barrel, your barrel's threads/lug shoulder are 100% square, the chamber is 100% cut square/true & perfect, that the bore in the barrel is 100% centered in the barrel, that your base screw holes are 100% centered to your action, that your base is 100% straight, and that your rings are 100% straight. And even if all these are perfect, you're just never going to beat the physics of gyroscopic drift of a bullet's mass spinning in a certain direction. [/QUOTE]
