Hello all. I have a "story" that has bothered me for a while. My father has told me for years that when he shot a .308 next to a .270 Win that the difference was like night and day with the .270 out performing the .308, especially in the trajectory category. Well......my dad re-barreled that old 721 .270 to a 30/06. To this day he thinks of the .308 as "pleasing on paper only" type of cartridge. What is funny is how he likes the .358, .243, and other .308 siblings, but still despises the .308. I want to buy a Tikka Hunter in .338 Federal, but i am starting to wonder if i should look into a .338/06. So, cutting to the chase, is the velocity difference and all statistics accurate concerning the .308 vs the /06, and .338 vs the .338/06? Do the shorter cartridges only lack 100-200 fps slower that their bigger brothers? Or are the differences in the field much more profound?
