Where I hunt I match my bullet to the animal. For example deer, I like fast, flat bullets usually BT style. For Moose and Elk I would rather have energy, so a slower bullet with max. punch. That being said I am not a believer in 200 grain leads works better for moose or elk, in my experience 160-180 well constructed bullet will get the job done just fine.

I rarely base my bullet selection on numbers published but rather by range, effectiveness, game and what shoots the best out of the rifle I intend on using.
