Actualy buy higher grain ammo. The more energy it takes to push the bullet out, the less kick. Equal and opposite reaction.
Mannygunner this is only my second post I dont want to flame but, the more energy that you have pushing the bullet the more energy that you will feel as kick . Just like the law of physics you stated for every action there is an equal and opposite reaction. The energy of the powder igniting pushes the case against the slide as hard as it pushes the bullet out of the barrel.
Well kinda.....
Physics laws are never broken, but the is a big difference between energy and momentum.
Most of the "kick" you feel is do tot he momentum imparted on the gun via the departure of the bullet heading in the opposite direction.
Note: momentum is proportional to the mass x velocity
energy is proportional to the mass x velocity x velocity
So for the same energy rating, say a 45 and a .357 the .45 will experience a much higher felt "kick"
In addition the time the bullet spends in the barrel will contribute significantly to the type of "kick" experienced. For extremely fast bullets like a 9mm or .357 the kick is sharp but tends to not cause much deflection of aim, resulting in more ease at firing in rapid succession while remaining on target, with .45 the bullet is much slower and it more "pushes" on you. Often resulting in displacing your barrel from the target.
The .45 has a smoother recoil though and so its easy to get a (relatively) smooth rhythm going. Where w/ a 9mm and .357 you are just going full tilt. (granted a 9mm feels like a toy compared to a .357), and the .40 is somewhere between the extremes.
if you look at some of the new sintered mega high velocity bullets in .357 (especially) w/ like 60-75 grain bullets at greater than 2000fps the kick is comparable w/ a small 9mm, but it just destroys the target.
Likewise a GIGANTIC .50 or larger pistol caliber at subsonic speeds still feels like a mule kick.
Obviously if you have both a big bullet and high velocities you are asking for the best/worst of both worlds. .454 casull anybody???
