I see no 7mm bullets over 175 grains. The '06 has 180, 200 and 220 factory loads.
A 7mm 175NP will do anything a 30-06 will do with a 200NP and the 200 NP is a better bullet in an 06 than any 220 i've ever used or tested. You really need a bigger case capacity than the 06 has, to use bullets heavier than 200 grain bullets.
Have you ever looked at the SD of all of these bullets to see why you don't need a heavier bullet than 175 grain in 7mm??

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.
