Thanks to all for the replies. Most appreciated. The responses inspired me to go out and test the winchester power points in 8mm 170 gr and 30-30 170 gr from various rifles. I didn't have any more Rem Coreloks in 30-30 left so that is why I used the PowerPoints. Here are the 10 shot averages:
From the Rem 700 24 inch barrel avg of 2,346fps
From the Rem 788 22 inch barrel avg of 2,133fps
From the Mossberg 464 lever 20 inch barrel avg of 2,029fps
The Winchester 170 gr power point ballistics on the box (I am assuming a 24 inch test barrel length) are 2,360fps for the 8mm mauser and 2,200fps for the 30-30.
Interesting results. I guess the increase in velocity and frontal surface area combined with more energy transfer (lower SD) of the 8mm saami spec loads over the 30-30 are enough to make a difference of what I see in the field. That is the 8mm saami spec load of the same weight is more effective on whitetails at close range (<125 yds) than the 30-30 carbine. Further it validates precisely what JimK and jmr40 have posted. I will take comments like American 8mm mauser loads are weak and no better than a 30-30 with a grain of salt. That said, the 30-30, while not a ballistic powerhouse, still gets the job done. Just not as effective as the 8mm saami.
In case anyone was curious, I also chronographed the Euro spec S&B 196gr SPCE ammo. Out of the Rem 700C I got a 10 shot avg of 2,524fps. This is about 70fps slower than what S&B claims on the box. Also, definitely more felt recoil than the Winchester PP ammo.
