"HSM BER300WSM168 Trophy Gold 300 Winchester Short Magnum BTHP 168 GR 20Rds HSM teamed with Berger to create an exclusive line of rifle ammunition loaded with Berger VLD hunting bullets which were previously only available to handloaders. These bullets are engineered to penetrate between 2"" and 3"" before expansion begins. Then the expansion process fragments the bullets. Shedding 40% to 85% of their weight as shrapnel into surrounding tissue and organs results in a devastating wound cavity. Because the vast majority of the bullet's energy is expended inside the target animal, quick and humane kills are ensured. These rounds are made with Winchester brass, match-grade primers and new powders that are not affected by temperatures and altitude. Premium components result in consistent performance and match-grade accuracy. Per 20. "
