300Win Mag- 178gr AMAX. Most devastating cartridge/bullet combination I have seen. I rarely use it anymore as the meat damage can be extreme.
I have noticed a generally higher level of trauma than smaller calibers when 30 caliber bullets are started at magnum velocities;especially with bullets designed for lots of splash.....this can vary a bit with bullet construction,but is the reason I have always "lumped" 30 caliber magnums with medium bores,like 338 and 8mm, giving similar velocity with similar weight bullets,etc.
Based on my own half-assed observations the next "breaking point" in the caliber line up is 375 bore.This SEEMS to me to be the point where I see more wounding trauma,but I could be wrong.
