Yeah, never trust a gun store employee, they often know less than the shooter.
My boss went to buy 357mags & the guy sold him 357sig. Good for me, I shoot that, so I got some cheap ammo. Most shops will NOT take back ammo, as they don;t know if you messed with it. So you are stuck in most instances.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
