Man, it must be my frame or something. I go out and shoot clays at a farmers field, he doesn't mind, we usually buy a few boxes of clays @90 clays each, and I'll shoot a case or so through my shotgun. It isn't odd to shoot a case, then when duck and goose hunting, I've had days where I've shot quite a lot of rounds, not to brag
(Some days it just seems like I can't hit.)
I would never say my 4570 is close to my 12 gauge, if I shoot 20 rounds through my 4570, I really feel it, off hand or not. I have shot the 325 leverrevolutions and now shoot 300 grain Federal fusions...
I've also owned a 7mm, 300 rsaum, and recently my buddy bought a 300 RUM, none of which I thought kicked as much as my 4570, and both of us thought the 4570 kicked more than the 300 RUM, as we brought them both out to sight in one day.
So, I don't know what to say, I even have a limbsaver slip on recoil pad over the factory, I did it because the length of pull was way short for what I like, but perhaps it doesn't fit right and is creating more abuse
IDK
All that being said, I love it, and if your buddy is in Alaska, I know I'd feel safer with a 4570 shooting some stopper rounds, as opposed to the 30/30. The 4570 may kick, but I can put that aside and still shoot it as accurately as I wanted from the outset. (3 shot tight overlapping clover leaf at 50 yards)
