Understanding the 7mm Remington Magnum
Historic Context
The 7mm Remington Magnum emerged onto the scene within the early nineteen sixties, a creation of the Remington Arms Firm.

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 effectively 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, which means it maintains its energy additional downrange, making it a wonderful alternative for long-range capturing.
