GURPS: Gun Fu gives special rules for allowing shotguns to use their effective RoF for things like Suppressing Fire and Spraying Fire as a cinematic rule. I'm inclined to permit the use of such weapon mods, known as a duckbill or gator choke, to allow the same in a realistic campaign.
I'm torn, however, between treating the attack as a narrow cone or just permitting spraying fire/etc. As a cone, based on performance in videos, I'd treat it as 2 yards wide at 1/2D range, and within 1/2 of 1/2D it's just shotgun rules as normal. As a cone, I'd also probably say you could aim it at a single target in the center and get maybe 2/3 of the shot in the center hex and 1/6 through the hexes on either side, or spin the shotgun/choke vertically to use mostly-normal shotgun rules.
Treating it as a cone, at 1/2d range you'd get 4 pellets per 12g 00 buck shell in each of the hexes if you aimed right between them, or if you aimed at a single hex you'd have 6 pellets and 1 on either side per shell.
Treating it as spraying fire would just use regular rules for lost projectiles across empty space/etc.
GURPS: SEAL's In Vietnam has stats for it.
ReplyDeleteAh, a book I've only ever opened because you said it was there. Should dig through that some more. The +1 to hit and Rcl 2 seem fair enough, but I still want something for hitting multiple targets with a single shot under the right circumstances, since it demonstrably can do so. Perhaps beyond 75% 1/2D, it becomes a 2 yard wide blast? I'll need to run some numbers yet.
DeleteI was a playtester for it. I butted heads with Hans a couple times on things.
ReplyDeleteAt the end of the day he's so very GERMAN.
Douglas Cole has a blog and a whole series on shotguns. What I'd treat the duckbill as a shotgun that can do suppressing fire. That way you don't have to write new rules.
Keeping track of every pellet is a book-keeping nightmare that will devour you quickly.
Sorry, when shooting at a point target, use the SEALs rule and don't worry about lost pellets.
DeleteIn actual use they used this thing to suppress, so use the suppression rules if the shooter doesn't declare a single target.
Yeah, that's nice and simple. Kind of what my original leaning was. Treating it as 2 adjacent spraying fire attacks, per the cinematic shotguns rules out of gun fu is similar in limited book keeping
