Just basic physics here - we can't "fool" physics, no matter how much shooting hyperbole we muster.

I started college as an engineering major, and I did that long enough to know there is no free lunch, no perpetual motion, no free energy, etc. That's why I didn't understand how a 7mm-08 could perform similar to a .270 with less recoil. I understand the difference between actual recoil and felt recoil. But there seems to be more going on that just perception.
Here is an excerpt from a Recoil Table seen
here:
(weight in pounds, recoil energy in foot-punds)
The above table does not take felt recoil into account. Yet it claims less recoil for the 7mm-08. Maybe it has to do with the pressure of the cartridge, burn rate of the powder, or something completely different. It seems impossible, which is why I started this thread.
The only thing I can think of is that the 7mm-08 accelerates more slowly than the .270.
Engineers on this board may be able to educate us re: impulse-momentum. I changed my major from ME to CIS, so this gets beyond me!
