What bullet weight should I be using? : AR10 - reddit

In fact, there is no way to convert PSI-CUP to PSI-PET, and most modern sources use CUP for copper crusher units as they aren't really PSI at all. We are left then to compare ballistics. After all, pressure and velocity are closely related, so if the same round using similar powder, and the same bullet produce similar velocity, then the ...

Internal, or initial ballistics (within the gun) Bullets fired from a rifle will have more energy than similar bullets fired from a handgun. More powder can also be used in rifle cartridges because the bullet chambers can be designed to withstand greater pressures (50,000 to 70,000 for rifles psi vs. 30,000 to 40,000 psi for handgun chamber).
