ORIGINAL: 48thguns
Hello DM. You called me....I supply emperical evidence. 175gr Nosler partition (the only one Nosler makes in 175gr.) vs 200gr Nosler Accubond. BC of the 7mm is .519....BC of the '06 is .481.
Given: 280MV is 2650 maxIMR load, MV of the '06 2688 max IMR load
E @ 300 yards for the 280= 1824; 400 yards=1581 zero at 250 drop=-19.1
E @300 yards for the '06= 2080; 400 yards=1782 zero at 250 drop=-18.9
Now which cross canyon Elk rifle would you chose? These are real numbers from real manufactures data. The defense rests. If you run all the numbers from ME to 400 yards, the '06 is clearly superior. The reason is and will forever be, the 30'06 is more versatile. Now, if you want to compare a Moose load/brown bear load with the 220's, the story gets worse for th 280. Yes it's a terrific deer antelope cartridge as with all the 7mm's, however, when it comes to the big boys......close but no cigar. Regards, Rick.
Our number don'tjivekemo sabe:
30-06....200 gr. Partition...MV 2650 fps...SD .301... BC .481
280... 175 gr Partition... MV 2800 fps... SD .310... BC .519
(from this point on I will give 06 data first & 280 data second respectively)
Trajectory @ 100 yds +2/+1.8; @200 yds 0/0; @300 -8.7/-7.5; @400 -25.1/-21.7
Energy @100 2708/2626; @200 2342/2459; @300 2016/2054; @400 1726/1788
What I read is that either cartridge is equally capable of taking game out to 300 yds. I think anyone who would argue one is better than the other just doesn't get it. In the real world the differences are so marginal that you could almost consider them identical. The 06 does it with a bit heavier bullet, but SD's are nearly identical. The 280 will do it with a bit less recoil. You decide which suits your needs better. I say that its splitting hairs.
