Why do we choose rounds differently?

For rifles used for hunting and tactical or other purposes we look for loads that are fast, penetrate and expand. Then for handguns I see the same guys advocating heavy and slow 45's. Seems to me that terminal ballistics work the same for rifles as they do for handguns. Rifles that shoot bullets at higher velocity do more damage on target than bullets fired at lower velocity. Example: .308 vs 10mm, both with 180 grain bullets. When it comes to damage which one wins? Duh, the .308. It just doesn't make sense to me. If I were to make a conclusion I'd say velocity is a very important part of terminal ballistics. For those who say that BPW isn't valid, explain why a 180 grain .308 does more damage than a 180 grain 10mm. Same weight bullet, the 10mm is even larger in diameter, but the .308 wins because it has a higher velocity. If all we are doing is punching lead through tissue it seems that the two rounds would perform the same. I guess the fact that .308 beats 10mm with the same weight bullet has something to do with a pressure shock. I dunno, not tying to start a fight, but I want to point out how silly it gets on here when we debate BPW and people say it doesn't exist. If it didn't exist 10mm 180 grain loads would equal 180 grain .308 loads every time, but they don't.
