Good advice here. Ironicly, it applies most to the postings by the poster giving the advice.
Ouch!!

...after 20 pages Vibe is entitled to a little pat on the back as he has been a very patient poster.

No. The rifle itself (barrel, action, stock) does not see anywhere near that much change in energy.A 2,000 horsepower kick in the shoulder? Come on.

But even it will hit you harder than the seat of your 500hp Hemi when you drop the clutch.
Geeze Bill. Power (and therefore HORSEpower) is a change in ENERGY per unit time. Newtons laws of motion deal in MOMENTUM. Momentum and energy are NOT the same. When shooting a rifle, momentum is conserved, energy is NOT.For every action there is an equal and opposite reaction. I wonder where Sir Newton went wrong and why no one else has noticed in the last 400 or so years.
What I like about physics, after you get past all the math, is that it is so simple.

When your Cuda starts leaving bruises on your butt..THEN maybe you might have a point. You're right...That was sillier.I'm about to make it uglier. (well maybe sillier!)
you said:

I'm not so sure - I come up with the Hemi applying a force about 5X to your whole body, as compared to what the gun applies to your shoulder. All based on your shoulder knocked back an inch or two in maybe a hundredth of a second, while the Hemi takes your whole body a few hundred feet in, say, 5 seconds.
You may have hit upon the issue Pacecil. I had thought we had been using a 9lb rifle - which would have about a 15ft/sec recoil velocity - which would be 129 ft-lbs/sec of power..or 0.23HP. Notice how this is close to what Bill has been stating. I think he's been measuring the wrong end.If you insist on thinking of recoil in terms of horsepower then you could if you wanted calculate the recoil horsepower of a 10 lb rifle firing our 200 gr bullet at 3000 fps. It's probably less than 125 hp. Does this seem reasonable to you?
