Heavier Bullet means less recoil? confused!

[CALI SHOT DOC]

So i was always told that i should shoot a heavier bullet in competition because it won't be as snappy and i'll have less recoil. I primarily shoot 9mm and i prefer the 115g because i seem to have less recoil and less snap. With 124 and up every round seems like its a +p round and just seems to be harder for me to control and reacquire my target. Whenever i'm at the gun show asking for 115g 9mm they always say just get 124/125g cause you'll have better control and less recoil and when i tell them that it's worse with 124/125 they look at me like i have no clue what i'm talking about


In a perfect world whats the relationship btwn bullet weight and recoil/snap?

Thanks for any input on this

In competition a lot of people use heavy bullets and light powder loads for less recoil.

[AAShooter]

Force = mass X acceleration.

When you fire the gun, you have equal force acting on the bullet and the gun. Given a particular force, a light bullet will accelerate fast. A heavier one will accelerate slower. Neither affect the force being applied to the gun.

Now if you run a hotter load, then more force more recoil. So a light bullet with a hot load will have more force than a heavy bullet with a light load. It isn't the bullet changing, it is the charge used to propel the bullet.

what they are refering to is that at a particular power factor, say 165 ( major power factor for uspsa) you can use a heavier bullet with less powder ( slower velocity) to achieve the power factor ( bullet weight in grains X speed in feet per second) and that a heavier bullet at a power factor of 165 will have less felt recoil than a lighter bullet going faster ( more powder).
