The question that I have had for years is to compare the 115 to 124 to 147 gains bullets....
What is the real world difference in them?

To calculate recoil force, use the link provided by MarkBinSC.
Four values are required.
1. weight of the bullet.
2. velocity of the bullet.
3. weight of the gunpowder.
4. weight of the gun.
We don't know the weight of the gunpowder so you can just use a small number for that, like .1 grains or whatever. But use the same number for all calculations to keep it simple. It will calculate recoil force.
Recoil force is one thing, but recoil also has a subjective component often referred to as 'snappy' versus 'pushy'. Check the value for recoil velocity. Light bullets are usually labeled snappy, and heavy bullets pushy.
This is usually attributed to how quickly a bullet has to accelerate to reach its speed. Since light bullets go faster than heavy bullets, light bullets have to accelerate faster, and this is blamed for the 'snappy' feel.
