>>47914170I'd probably a 9mm long gun with a scope and silencer. Quiet as heck, easy to find ammo in America, and can clear out the area from high ground. Crossbow would take a lot more skill at any distance, and I can carry a lot more 9mm than bolts and I'm sure 9mm is easier to find than bolts (e.g. I've got 1000+ in my closet). Can also share bullets with pistol or subguns.
