Just old rules of thumb. For the most part they will guide you correctly, as most cartridges we choose from can deliver those numbers inside our typical kill ranges of 300 yrds or less.
The most accurate rules of thumb are s.d. And impact velocity...assuming bullet construction appropriate for game intended. If you go light on s.d. Then you need to compensate with a crapload more impact velocity. If you have big s.d. Then you can hit em a lot slower. The whole thing is a sliding scale and each class of animal needs more or less. There’s an efficiency loss with high velocity low s.d. Imo, for the recoil or powder burned you get more from high s.d. And moderate impact velocities.
