And the really big guys absorb every bit of it and really get hammered. I think the 5'11" 160 pound hunter has the advantage over his larger counterparts when shooting really powerful rifles; in that he can move with the recoil impulse. If I couldn't move with the recoil of the rifle, the thought of shooting a .500 would be unbearable. Then if for some reason the piece doubles on you . . .
The following video starts with our hunting partner shooting his M-70 .375, then switches to me getting the basics on handling a double rifle. I messed up the editing at one point and it sounds like 3 rounds are fired from the double rifle . . . good trick huh. But note the muzzle rise on the last shot; I harped the triggers, which happens when the dope on the rifle has just the tip of his finger on the front trigger, as if its a target rifle, and the recoil of the first shot, causes my finger to slip past the front trigger and slap the rear one. Recoil was no worse than firing a single shot, because they were two separate events, but they happened in quick succession causing the rifle to rise high in recoil and the report sound like a single shot.
