So instead of how many layers of drywall a payload of lead can penetrate we need science to intervene...
First we need to replicate a real exterior wall in all forms and materials... COMPLETE WITH INSULATION AND EXTERIOR VENEER MATERIAL...
Set up a chrony system on the exit side... Now fire various rounds thru it... Now we have a velocity, projectile weight and cross section dimension and shape...
Now we need to load a similar "model" into launching barrel that can precisely launch these models at the speed they exited the first wall...
Now we can fire at walls from outside to determine if these lead projectiles can penetrate and with the chrony system now on the "interior" side, we would know, to an extent, the efficacy of them...
