Faster & Light for Caliber Rounds

Dr. Gary Roberts, Chuck Haggard, and many others have explained the concept of faster velocity and light for caliber does not perform to the level as their mainstream counterparts.

Light and fast for caliber rounds typically encounter subpar penetration and are greatly negatively affected (due to lack of mass) if the projectile expands. Bullet construction (shape and materials used) play a huge part in terminal ballistics.

This concept has been brought up in threads but hasn't had it's own thread.

There seems to be a consensus range for projectiles for each cartridge.

Say for 9mm the size range is 115-147/150 grain. There is probably a velocity range also. Those normal ranges exist because outside of them rounds don’t work very well.
