[QUOTE="RMulhern, post: 714659, member: 999"] Here's my 2 cents worth! New shooters coming into the LR venue often find it difficult to believe that SD is a goblin that will jump out of the bushes and eat their lunches but it doesn't take them long to figure out that "Hey....I've got a dead nuts zero on my rifle at 100 yards but my bullet impact was 14" right at 1000 yards!" Nothing can teach this better than when shooting long/slow/heavy bullets at long range. I've been shooting M1874 Sharps rifles for quite a few years now, in addition to all of my smokeless powder rifles, using cast lead bullets with weights ranging from 500 grs. up to 720 grs. with velocities running from 1250 fps up to 1400 fps. If I were to go up on my range here at home on an ideal day aka absolutely no wind and visible mirage and get a dead nuts wind zero from 100 yards and then go back to 1000 yards to shoot which I do on a regular basis and use the 100 yard wind zero....I probably wouldn't hit the 72"x72" mainframe steel plate with a good break and call!! Why? The same dead nuts wind zero that I had obtained at 100 yards would have the point of impact at least 35" to 40" right of my aiming point due to imparted SD delivered by the right hand 1-18" twist built into the rifles barrel!
