.458 SOCOM VS .308 WINCHESTER

Although both are very powerful and efficient and have been used in the military for decades which in itself is a testimony of the quality of both these rounds. But still when two things are compared one is better than the other if not much then slightly. here we are going to find out which ammo is better than the other or both are equally good and it's just a matter of kind of use one has.

One major difference between the two is the effectiveness of .308 Winchester in shooting past 300yard that’s the reason .308 is preferred in medium to large size games. Developed in 2000, the 458 Socom Ammo was an upgrade for the standard M4/M16/AR-15 family of rifles. In contrast, the 308 Winchester came about in 1952, decades earlier than the birth of 458 SOCOM. Moreover, the 458 SOCOM was practically designed for AR-15, M4, and M16 rifles while the 308 Win was cham-bered for an AR-10.because of the higher weight of .458 it has more arch and drop than .308..458 drops after 300 yards whereas .308 can go beyond 1000yard. .308 WINCHESTER IS CHEAPER THAN .458SOCOM..308 weighs between 125gr to 175gr and .458 is available between 250gr to 600gr.

308 & 458 SOCOM Bullet Energy

With heavier bullet weights, the 458 can put more energy into any target at subsonic speeds com-pared to the 308 Winchester. And although the 308 could stomp over the 458 SOCOM in the dis-tance, the 458 would stomp on the 308 for bullet weight and will take down just about any target you wish to hunt. Always remember that for a heavier game, the heavier your bullet should be because heavier slugs always carry more energy. With this, the 458 SOCOM takes another win.
