[QUOTE="Dr. Tad Hussein Winslow, post: 1294404, member: 7123"] Really kind of a shame that they would not choose a better chambering & caliber, as long as they're doing a major upgrade like that: 1. .300 Win Mag, w/ 208 Hornady A-Max (.635 BC): 1,000 yard total drop: [B] 315.7". [/B]1,000 yard drift in 10 mph x-wind: [B] 60.56"[/B] (based on 2850 MV). 2. 6.5mm-'06 A-square, w/ 140 Berger VLD (.640 BC): 1,000 yard total drop: [B] 278.2" [/B](12% better than .300 winmag). 1,000 yard drift in 10 mph x-wind: [B]53.86"[/B] (11% better than .300 winmag) (based on 3000 MV). And, with (a) a lot less recoil/blast, and (b) a lot less powder, brass, and bullet cost. Not to mention - no PITA belt. Also, with the likely bullets chosen in these respective calibers for military use, the discrepancy will likely be even larger, as the 208 A-Max is more of a BC anamoly in .300 than the 140 Berger is an anamoly in BC terms in 6.5 bullets (each relative to weight & thus vel, mind you). Now the .300 winmag/208 will have 1229 ft-lbs of retained energy, which is 27% better than the 968 ft-lbs of retained energy of the 6.5-'06/140 at 1,000 yards, but how much more energy than 968 ft-lbs do you need to do the job? Since killing a person through SBA requires ____ ft lbs, roughly? (I don't know; I'm asking). Less than 500? The .300 win mag will also have slightly more penetrative abilities through intermediate hard barriers than the 6.5m-'06, due to roughly the same SD, but with higher mass (though at bit less velocity), so maybe that's a factor... 968 ft-lbs on target trumps 1229 ft.-lbs of miss. Anyway, I'm sure they have their reasons. I just hope its more about wanting that energy & penetration (e.g. contemplation of anti-materiel or HBA-busting use), than it is organizational inertia and/or ignorance of facts. [/QUOTE]
