[QUOTE="Eaglet, post: 81648, member: 3756"] From ballistic explorer I got this information: [ QUOTE ] [b]Momentum[/b] An indication of a bullet's knockdown power is momentum. Doubling either the weight (mass) or velocity of a bullet doubles its momentum. Clearly it's energy that makes bullets deadly to game, yet it's momentum that knocks game off its feet or knocks metal targets over. [/ QUOTE ] If that is true, then a 308 Winch. with 175 gr. bullet will produce about [b]2000 f/lb[/b] at 180 yards, most of us will agree that's good medicine for elk, the momentum would be about 57 lb-f/s which the 375 H&H with 260 gr. bullet and MV=2800 f/s accubond will produce the same momentum at around 760 yards even though the tables tells us it would only be [b]1365 f/lb.[/b] of energy. What are your views on this matter? Would the 308 Winch. kill it faster at 180 yards than the 375 H&H at 760 yards? Would you trust better the 308 Winch. at 180 yards or the 375 at 760? Thanks in Advanced. Javier O Moncada. [/QUOTE]
