Okay, after reading something on here a month or two ago about this, it got me thinking about my science classes a couple years ago... That there is an "equal and opposite reaction" to everything. Now, if I'm not wrong, or confused here, wouldn't it be if you fired a gun that has, say 1000 foot-pounds of energy at the muzzle of your firearm, wouldn't you be hit with 1000 foot-pounds of energy also? Anyone wanna explain??

no, i dont think so, but acually, i understand about 20% of a rounds energy moves the projectile, the rest goes through you. but keep in mind that energy goes through the rilfe and stock first.

The *momentum* of the bullet + powder gases is balanced by the recoil momentum of the gun. Momentum is mass * velocity, or m*v. Kinetic Energy is m*v*v/2. So if the mass of the gun is, say, about 100 times larger than that of the bullet (think 500 grain 45-70 in a lever action carbine), then the bullet carries away 100 times more kinetic energy than the rifle. Plug and chug.
