Bartkowski, the easiest way to compare recoil is to first assume equal weight rifles. That's easy enough, right? Okay: Add the weights of the bullet and the powder charge, and multiply by the muzzle velocity.
That will yield the recoil ratio between any two cartridges.
Okay, loads vary, but these are reasonable:
.270: 130-grain bullet, 50 grains of powder, 2,900 muzzle velocity.
7mmRemMag: 140-grain bullet, 70 grains of powder, 3,200 muzzle velocity.
522,000 vs. 672,000. The .270 has 78% of the recoil of the 7mm RemMag.
Note that there is nothing in this about *how much* recoil there is for any package of cartridge and rifle. It *only* compares loads.
If you're comfortable with the recoil of a .270 in, for example, a seven-pound rifle, odds are you'd be comfortable with the recoil of a 7mm RemMag in a nine-pound rifle.
That will yield the recoil ratio between any two cartridges.
