Depending on what you’re shooting, there’s always a little bit of recoil, sometimes it’s hardly noticeable, like the AR-15 — unless you’re a journalist with the New York Daily News. On the other hand, a rifle like .950 JDJ, has a kick that leaves a lasting impression and probably a bruise the size of a dinner plate.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
