O.K.... you are using the Nosler book... Do you realize the load I mention for my 7rem is already 2 grains OVER Nosler's book and still only clocking 3,000 fps; Nosler is over 3300 with a 140 and rl22... We've seen this time and time again with the 7rem no matter the powder or bullet weight. Serious overestimation of the velocity potential. I don't worry about it; I've got bigger toys in the safe and refuse to wind up a cartridge for a couple hundred fps. If it's your only rifle though, it can be a hassle. I load for a buddy's 300roy that is the same way. A bit slow, but a good shooter.Not sure what books you're using, but the 7 Rem Mag is right around 300 fps faster than a 270 Win with equal weight bullets according to Nosler (and all my other resources and personal experience loading both)...
Click Here for 264 WM 130 gr ≈ 3200 fps, 140 gr ≈ 3050 fps
Click Here for 270 Win 130 gr ≈ 3150 fps, 140 gr ≈ 3000 fps, 150 gr ≈ 2900 fps
Click Here for 7 Rem Mag. 140 gr ≈ 3300 fps, 150 gr ≈ 3200 fps
Even if you ignore B.C., 270 doesn't beat 264 Win Mag, and it's not even in the same zip code as the 7 Rem Mag.
270 Win, 140 Accubond @ 495 yds ≈ 2100 fps, 1350 ftlbs
264WM, 140 Accubond @ 535 yds ≈ 2100 fps, 1350 fps
7 Rem Mag, 140 Accubond @ 625 yds ≈ 2100 fps, 1350 ftlbs
7 Rem Mag 160 Accubond @ 555 yds ≈ 2100 fps, 1550 ftlbs
When you consider B.C., the 264 slowly walks away from the 270 as it goes down range, and the 7 Rem Mag can deliver 15% more bullet on target with less drop/drift than the 270 Win.
The load for my 270 is running 50 fps or so off from book. I consider both the 7rem and 270 mid range cartridges so I really don't care about better than 400-500 yards and any pointy bullet is fine to that point.
