Someone mentioned higher-velocity rounds having more recoil...I'm pretty sure that's not really a thing. At all. .22 versus .45 anyone?
Silly comparison, but I think it illustrated what I've always assumed to be true...bullet weight goes up, velocity goes down. Seems kinda 'duh,' but it's not as simple as 'the heavier thing is harder to accelerate,' is it?
All anyone ever rates ammo with is bullet weight, various velocities (muzzle, 50ft, ect), and pressure. Pressure being in the form of +P. Or +P+. Or +P++PPP+++PP+P+ or some shit if you're one of those dudes that enjoys reloading your own ammo and Glocks exploding in your hand. :awe:
What does powder charge do? I think I've always assumed that the amount of powder goes down as bullet weight goes up...it's not just 'x' amount of powder accelerating a 114gr bullet more easily than a 147gr bullet...it's the heavier bullet being a greater opposition to the expanding gases, so the amount of powder must decrease to to allow cartridge pressure to remain in spec. Right? Maybe? I dunno.
