Do you realize what you have started with your statement pasted below? Heads will and are both exploding and imploding.
“Some might mention "physics" as the reason due to the larger diameter of .270 bullets, but have hard time believing an extra .013" in bullet diameter makes any perceptible difference--since it's about the thickness of the average business card”
How many times have we heard some fire members extolling the virtues of the 280 vs the 270? The difference between these two cartridges is less than the previous referenced .013”. Just stiring the Christmas pot.
