Have you shot the 180 hybrid out of your 7? I am guessing you might get 2800 fps out of a 26" barrel? And I'm guessing 2750 is possible in the 300 SAUM for the 215's out of a 26" barrel. You might be able to get a few fps more with te 180 but the 215 has a higher BC so it's basically a wash. I base that on my own experiences withe 7 RM and 300 WSM. I was able to get 2930 shooting 210 Bergers with RL17 out of a 24" barrel. With H4831, I'm guessing I could have got 2750. And the 215's are a little faster bullet than the 210's.
Bottom line when you compare apples to apples, the external ballistics between the 7 and 300 are going to be very close. But when it comes to terminal ballistics, the bigger cal wins.
No I don't own either of the SAUM. I was giving an example. Still a topic, fertile grounds for discussion, but I'm a simple guy and just look at the outcome, the dead deer, etc. I'm less concerned about all of the ballistic characteristics out there than most. I hunt with what I like and have and make the best of it and just check my trajectories and go hunting.
There's no shortage of guys out there who will make good points about how a 7mm trumps a .277, and so on but I am content with what my rifles and ammo do and they have served me well at all distances I have killed game, some of which I would be accused of being dishonest with what my plain old 270 Win has done in Wyoming and Colorado
