Our velocity charts are labeled with bullet weights and barrel lengths with velocities gathered. We also used the data gathered to suggest optimum barrel lengths for each cartridge to help decide which was best. Different states hunting laws are slightly different and are subject to change so we included case lengths for each for you to use as a guide if they are legal for your hunt or not. Each cartridge has its own benefit and ultimately is your choice. You can find more information on our site under the Velocity/Info tab labeled Velocity Testing.
