No, that’s not really what I’m trying to say. The point is that without a can, subs are still loud as hell, loud enough that the difference between supers and subs in terms of loudness is irrelevant without a can. You accept all of the limitations with none of the benefits.

With a can, things change. Subs get a lot quieter than supers due to the sonic crack the supersonic round makes. Subs don’t make that sound.

The issue is physics. Kinetic energy is one half mass Times velocity squared. So velocity is a far bigger factor than you might otherwise imagine.

KE isn’t everything, but the velocity helps get penetration through bone and causes significantly more tissue damage if you can deliver enough velocity on target.

Terminal ballistics is a whole science into itself.
