Shotgun Slugs

[WasteAid]

How should the damage for shotgun slugs be figured in 4e?

also any thoughts on other shotgun ammo related subjects would be appreciated such as: Rifled shotguns (deer guns), Saboted slugs, Military rounds (flechette), or special purpose rounds (bean bag or lock breaching)

Thanx

The SWAT team at the local Sheriff's office says that shotgun bean bags are too inaccurate so they've switched to foam rounds developed for the military that are fired from a 40mm breach loading rifled grenade launcher, with an effective range of around 40 yards. (They still use 37mm for smoke.)

I wounder how many rogue cyborgs it'll take before they grab some 40mm HEDP rounds. ;-)

Also, should the dmage for multiple projectiles at less than 10% of 1/2D still be pi- or should it upgrade to pi, pi+ or maybe even pi++?

For rouge cyborgs you could use the APDS rounds described on Gurps 4e pg. 280, swap out the Tungsten dart with silver (or maybe a silver slug) for Werewolves, and with wood for Vampires. Shotguns are so useful. . .

A full bore slug at 1500 fps (about 437 grains) would do 5d pi++

I saw a rule of thumb on the Pyramid boards (I forget who posted it), suggesting x3 damage, and x3 range over shot. As the shot loads are assumed to have nine pellets, this makes sense (in terms of damage).

This gives a 12 gauge slug 3d+3 pi++. For flechettes I'd give them the same damage as shot, a (2) armour modifier and pi- damage (IIRC Hans has said shot should do pi, not pi-).

I'd give slugs the same acc as shot, unless the gun has rifle style sights, and/or is rifled for slugs, in which case I'd give them +1 acc. More than that would make them as accurate as modern long-range rifles, which seems excessive.

Dedicated slug guns shoot in the 2 to 4moa range.
Rifled slugs through a smoothbore IME shoot 4 to 6moa on average, with the exceptional gun,choke, and load combo that will shoot as well as a rifled gun.

The thing is for damage, the rough progression in terms of penetration that I worked out from 3e still holds. So a 437gr slug, 18.5mm, 1585fps should do about 5d damage. Clearly it's pi++ due to size. For a smaller load, at 1350fps, that's 4d+1 (not that different than the 3d+3 you suggest)

For shot, some large buckshot is pi (00 and 000 buck); everything else is pi- or smaller, per pellet. For some loads, you actually need to group pellets together to get a meaningful number of pellets, penetration, and wound number.

Granted, this is all using my ballistics article based stuff; but I think it holds water.

I'd call this Acc 5 and 4, respectively. Acc 5 is typical for assault rifles, which are in the 1.5 to 4 MoA range. This puts the second category in "slightly worse than Acc 5" range, I'd say.

I agree with you 100% DouglasCole.
