Although there are many uses for rifles and many forms of rifle competition, as a practical rifleman our concerns are chiefly hunting and defensive uses of the rifle at reasonable ranges. Reasonable ranges may be defined as the distances at which we can expect to be taking game or defending ourselves and can quickly and reliably get first round hits under field conditions. Let me say that again: quickly and reliably get first round hits under field conditions. For most of us, this distance is going to be from right off the end of the muzzle out to 300 or 400 yards. Practical rifles are those rifles suited to hunting or defensive use that are sufficiently lightweight and user friendly to be carried all day.

Getting Zeroed
Zeroing a rifle means adjusting the sights so the point of aim and the point of impact intersect at some predetermined range, referred to as the zero range. Whether using iron or optical sights we can imagine the line of sight as being a straight line and the bullet path as defining an arc. We adjust the sights so the barrel is actually pointing up in relation to the line of sight. Once leaving the barrel, the bullet will cross the line of sight at the initial intersection then cross the line of sight again as gravity draws it back to the line of sight, referred to as the zero range, usually something like 100, 200, or 250 yards.
