Since it's introduction in 1963 by Winchester, 300 Win Mag has proven itself worthy of being one of the most well-respected big game cartridges out there, and can be used for even the largest deer and antelope species. When not being used for hunting, this cartridge handles long range shots with the best of them, but does come with a heavier recoil than many smaller calibers more suited for target practice. Freedom uses a magnum large rifle primer and high end powders to focus on consistent chamber pressures, which inertly provides excellent accuracy.
