[QUOTE="codyadams, post: 1533363, member: 87243"] I'm not sure I would exactly say that is proof that one has better ballistics than the other. If we assume that velocity difference between the two is approximately 30-50 fps, and also that they both are exactly identical for POI as far as zeroing (which is rare, but can happen) then if you throw that info into applied ballistics, then with my atmospheric conditions, you see that the Berger does in fact overtake the Hornady in drop.....at around 2,000 yards. The Berger does in fact overtake the Hornady in velocity.....at about 1,600 yards (when they are nearly sub-sonic). And finally, the Berger does in fact overtake the Hornady in wind drift....at about 2,200 yards. Considering they were shooting at 2,640 yards, that completely makes sense. But, especially in a 6.5 caliber, this has exactly zero relevance to any hunting scenario, because the 147 does not really get outdone by the 140 in any meaningful amount until they become sub-sonic. However, it is very interesting when considering these two bullets for ELR, 2,000+ yards. In that case, the 140 Berger does in fact out perform it. I guess it comes down to what you use them for, for ranges from 500-1600 yards, the Hornady does better. From 1600 until the bullet can't go any farther, the Berger does better. As far as terminal ballistics however....My vote goes hands down to the Berger. Just make sure you clear out those hollow points. Very cool video, thanks for sharing. [/QUOTE]
