Have any of yall ever wondered what made the military choose the .308 win over the .270 win. I recently started wondering that when I was messing around on the ballistic calculator on my phone I began comparing the ballistics of the .308 and the .270 to see what the how different conditionds effect the flight paths of the bullets. At first I was just using the best flying cartridges from both the .270 and .308,but then I decided to try the exact same cartridges. What I found was that the .270 had better ballistics as far as bullet drop and wind drift when put under the same conditions as the .308. Have any of yall wondered this or even know why the military doesn't use .270 over the .308?
