  • The 7mm Shooting Times Westerner (7mm STW) is a high-performance rifle cartridge designed to offer superior accuracy, power, and energy with every shot. Developed in 1981 by Remington Arms Company, the 7mm STW is based on their popular 7mm Rem Mag round, but with improved ballistics and powder charge capacity.The 7mm STW offers flat trajectories and excellent ballistic coefficients due to its higher velocity. This results in less drop and “drift” compared to other rounds when shooting at long distances, making it an ideal choice for competitive shooters looking for precision accuracy.For general hunting or varmint shooting purposes, the 7mm STW provides plenty of power to quickly take down your target with ease. Whether you are competing against others or hunting in the wilds of nature, the 7mm STW should certainly be considered for your needs.
