Sectional density and ballistic coefficient additionally come into play. Sectional density refers to how heavy a bullet is in relation to its diameter. A better sectional density helps a bullet retain velocity and penetrate deep right into a goal. The ballistic coefficient (BC) describes how properly a bullet resists air resistance. A bullet with a excessive BC flies extra effectively, retaining extra velocity and vitality over lengthy distances. The 7mm Rem Magazine can use bullets with nice BCs, that means it maintains its energy additional downrange, making it a wonderful alternative for long-range capturing.
