I believe that the size and shape of the butt, whether or not it has a soft recoil pad in place, the LOP, the pitch, the DAC and DAH all affect felt recoil. I would add that I can feel a difference with different shells at exactly the same velocity sometimes. Some have a "sharper" recoil than others, not hurtful, just a noticeable difference, possibly because of powder burning rates? I dunno. I just know I often notice it, and after 20-30 rounds I no longer do.

Some even argue that lengthened forcing cones affect felt recoil. I have no opinion on that one................ I can't prove it either way.
