308/7.62×51 150 grain Speer Spitzer
The 308/7.62×51 150 grain Speer Spitzer with a 150 grain Speer Spitzer bullet traveling at 2,850 feet per second (fps) is a commonly used load for medium to long-range shooting. The 150 grain bullet weight is a versatile choice that offers good accuracy and ballistics, making it a popular choice for target shooting, hunting, and tactical applications. At 2,850 fps, the 150 grain Spitzer bullet is capable of delivering effective energy transfer and relatively flat trajectory, making it a reliable option for medium to long-range engagements. However, it’s important to note that actual velocities may vary depending on factors such as barrel length, temperature, and altitude.
This round is similar to M80 Ball, but is more accurate and has a hunting projectile with excellent Terminal Ballistics. It is made with new, surplus, Lake City 7.62 x 51 brass. It is primed and annealed by Lake City. Tested and developed in AR-10 rifles. It runs semi automatic rifles flawlessly. 1/2 MOA possible.
Not all barrels are created equal, chronographs don’t always agree with each other and atmospheric conditions affect velocities. That being said, we believe that you can expect to get around 2,850 fps out of a 26″ barrel with this round.
While rifled guns did exist prior to the 19th century in the form of grooves cut into the interior of a barrel, these were considered specialist weapons and limited in number.
