My 12ga with the plug out holds 5. Narrow area 30’, #4 buck, I’d take my chances. Oh and I don’t rack it to let anybody know I’m serious. First thing you hear is the last thing you hear.
I once had to take the 12 gauge out and interrupt some car clouters Being quiet while I racked the first round was a challenge.
Haven’t messed with #4 buck. OO at 60 yard will go through a deer’s lungs and lodge against the hide. Either one, inside 30’ should do the trick.
