When someone says to use lighter loads, does this typically translate into a heavier bullet? From what I can tell, it seems that the higher grain bullets tend to have a lower muzzle velocity. I'm no expert on physics, but this would seem to make sense being that a heavier object would require more force to move it forward at the same speed as a lighter object. It's often recommended to practice with lighter loads when needing to reduce recoil, but I was just wondering if lighter really means heavier. Or am I way off base here?
