At first I doubted this. I couldn't calculate recoil force of these two calibers to have a comparison, but I do know muzzle energy.

With the .243 using a typical 100gr. psp bullet and the .270 with it's 115gr. managed recoil psp, I see the energy in foot pounds is 3.75% greater at the muzzle with the .243 over the .270. Interesting.
