  2. Shot grouping - Wikipedia

    en.wikipedia.org/wiki/Shot_grouping

    The group on the right measures about 7 mm and was fired at about 90 meters, which equals ⁠ 7 mm / 90 m ⁠ = 0.08 mils (0.3 in group at 100 yards, approx. 1.047′×0.3 = 0.314′). In shooting sports , a shot grouping , or simply group , is the collective pattern of projectile impacts on a target from multiple consecutive shots taken in one ...

  3. .44 Magnum - Wikipedia

    en.wikipedia.org/wiki/.44_Magnum

    The limiting factor is the bullet's trajectory: the best hunting bullets are heavy, so they are relatively slow. This means the projectile's trajectory will drop significantly at ranges beyond 100 yards (91 m); there will be virtually zero significant drop at 50 yd (46 m), so the gun's aimed "line of sight" can meet the "bullet's trajectory" at ...

  4. Point-blank range - Wikipedia

    en.wikipedia.org/wiki/Point-blank_range

    Point-blank range is any distance over which a certain firearm or gun can hit a target without the need to elevate the barrel to compensate for bullet drop, i.e. the gun can be pointed horizontally at the target. [1][2] For targets beyond-blank range, the shooter will have to point the barrel of their firearm at a position above the target, and ...
