    en.wikipedia.org/wiki/Rifleman's_rule

    The drop values are measured or calculated assuming the rifle has been zeroed at a specific range. The bullet will have a drop value of zero at the zero range. Table 1 gives a typical example of a drop table for a rifle zeroed at 100 meters. Table 1: Example Bullet Drop Table

  3. Shot grouping - Wikipedia

    en.wikipedia.org/wiki/Shot_grouping

    Handguns are typically less accurate; at a shooting distance of 25 yd, a grouping is considered acceptable for self-defense if the shots fall within a circle of 4 to 5 inches, which is 15 to 19 MOA (equivalent to a grouping of 100-150 mm at 25 meters, which is 4-6 mils), [9] representing the shot pattern needed to hit the vital organs of a ...

    en.wikipedia.org/wiki/Ballistic_table

    Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

    A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

  7. Sighting in - Wikipedia

    en.wikipedia.org/wiki/Sighting_in

    Each group is described by the minimum diameter circle perpendicular to the axis of bullet movement including the impact point of all bullets in that group. [1] A firearm consistently placing bullets within a 1 inch (25 mm) diameter circle on a target 100 yards (91 m) from the muzzle might be described as capable of 1-inch groups at 100 yards.

  8. Winchester Super Short Magnum - Wikipedia

    en.wikipedia.org/wiki/Winchester_Super_Short_Magnum

    For example, if we compare the .25 WSSM to the .25-06 Remington, we find that the .25-06 requires a .30-06 length action, commonly called a standard or long action. The .25 WSSM case which is almost a full inch shorter, can make use of an existing short action such as used by the 5.56 NATO and .223 Remington family of cartridges. Some ...

  9. .270 Winchester - Wikipedia

    en.wikipedia.org/wiki/.270_Winchester

    The .270 Winchester cartridge is equipped with a 130-grain bullet traveling at approximately 3,060 feet per second (fps). When sighted in to intersect 3 inches above the line of sight at 100 yards (about 90 meters), it maintains a trajectory that rises no more than 3.5 inches and aligns with the line of sight around 270 yards.
