The .30 cal is going to be much quieter than the .257 cal. Huh? The .30 will use more air, hence more noise. Am I missing something?
.257 is not .25 cal
Bigger, heavier bullets are less affected by atmospheric conditions in longer range shots.

So "bigger' is incorrect. "Heavier" is correct.Using a very heavy .257 is better in some ways than the same weight .30.
