Oh noes!! My faith in jfru!!
Please tell me you didn't write that yourself, and have that much knowledge of "vampire lore."
fistful:
I have read Bram Stoker's Dracula and a few other vamp books. I also have watched a few vamp movies. I might even admit to having played RPGs--deeandee--under threat of bodily injury.
I consider it akin to "Scary Movie" lore. If you have any contact with the mass culture and have an IQ above room temp, you are going to notice this stuff.
If I am thinking a slug with a special payload, I am thinking a foster hollow-point slug made from pure lead with a capsule containing holy water in the hollow point. So, when the toothy target types are serviced, they not only get a sug through their innards, the yget holy water sprayed through them.
I think my tactics might be something along the lines of:
1. Fill vamps with 12ga slugs until incapacitated
2. Hack off their head with a machete, sword, axe, whatever
3. Repeat as necessary
I must admit to being intrigued by the application of a SAW or any belt-fed. I'm thinking maybe a 7.62mm shorty machine gun would serve quite well.
I wouldn't recommend water. In a rifle or pistol JHP, definitely not. Even in a 12 guage slug... If the water is superheated and converted to steam, it'll burst the slug. If this happens in the shotgun, bad things. Sure, you could cut the powder loads in shells, but I dunno. Risky unless you perfected some encapsulation method. I'm not saying it's not a good idea, but you'd want to test the everloving excrement out of it first.
Manhandling a 12 guage and a sizeable edge weapon ain't easy, especially in close quarters. Again, it'd take some experimenting to work out the kinks. I still say for cleaning operations, you need a four man squad.
A shorty 7.62 NATO MG is a bad idea for indoor application. First off, it'll punch through the undead. And the walls. And Gods knows what else. Less ammo. Plus it is NOT as controllable as a 5.56 shorty MG. The idea is suppression, not actually killing the bad guys. Altho, with the rate of fire... in an enclosed space, a SAW as just a semi 12 guage on a steady diet of PCP and LSD. With better ballistics to boot.
Fully extended - Yea, you have a lower velocity and thus shorter range, but good enough for suppression and grazing fire.
Compacted - See? I'm not that big of a guy (6'2) and you can see how relatively compact it is for nest clearing. Not that much larger than your Saiga 12's, and your shotguns cannot provide suppressive fire.
