[QUOTE="gunners, post: 1177332, member: 77186"] It's funny how the original question was best for deer to 600-700 yards turned into elk at a 1000yd. My option would be to go with the 7 mm because it will kill just as well as the 300 at those distances on that animal with less recoil. If he said elk it would be different for sure. As for trying to argue with the velocities of the same bullet weights is not a good argument at all. I think the merits of bullets BC should be offset by its SD so you'd come up with a "caliber weighted efficiency" so you can sort of work out what brands do a better job G7 divided by SD Hornady's new ELD's 6.5mm 143gr G7 .315 SD .293= 1.07 7 mm. 162gr G7 .308 SD .287= 1.07 7 mm 175gr G7 .330 SD .310= 1.06 308. 178gr G7 .271 SD .268= 1.01 308. 200gr G7 .315 SD .301= 1.04 308. 212gr G7 .336 SD .319= 1.05 338. 285gr G7 .394 SD .356= 1.10 Bergers VLD 6.5mm 140gr G7 .307 SD .287= 1.07 7 mm 168gr G7 .316 SD .298= 1.06 7 mm. 180gr G7 .345 SD .319= 1.08 7 mm. 195gr G7 .387 SD .345= 1.12 308. 175gr G7 .265 SD .264= 1.00 308. 190gr G7 .290 SD .286= 1.01 308. 210gr G7 .320 SD .316= 1.01 338. 250gr G7 .351 SD .313= 1.12 338. 300gr G7 .417 SD .375= 1.11 I think that's easily understandable and it would appear there is a slight loss in performance with 308 cal for some reason their G7 numbers need to be higher by 2-5% to match 6.5 and 7mm I don't know what does everyone think?
