We see that the averages of the two cartridges is still pretty close with less than 3ft.lb of force difference between the two. By the time the rounds reach the 300 yard mark, there is only 4lb/ft.s of momentum difference between the rounds of the different cartridges. As you can see, there is a significant difference in the bullet trajectories between the two cartridges. It is a well known cartridge, capable of travelling long distances with lots of energy to knock down your intended target. We see a significant drop in recoil with the lower grain bullets than the heavier bullets which is expected, for both cartridge types. These projectiles quite often take advantage of the latest developments in bullet development and offer advantages in precision and ballistic coefficient compared to the bullets used by the .270. You don’t have to be relegated to only one cartridge and feel it deserves all of your loyalty. John While there are some rounds from each cartridge that are pretty similar in velocity, the trend of the .270 rounds having an average of 200-300ft.sec more velocity than the .308 rounds extends out to the 500-yard mark.
