Modern Monster Hunting Guns [XM500, MICOR Leader 50, etc.]
Do we have official GURPS stats for compact rifles firing anti-materiel rounds, like the Barrett XM500 and MICOR Defense Leader 50, both in .50 BMG?
I'm primarily wondering what the shorter barrels do to GURPS Acc, i.e. whether breakpoints for -1 Acc should be at 24" barrels, 20" or 17.6" barrel for the .50 BMG. All of the above are rated as Bulk -5 and Acc 5 for 5.56x45mm and 7.62x51mm, but the .50 BMG might require a longer barrel by default and count as 'carbine' in anything 20" barrel and shorter. I'm also wondering about Rcl and ST. The M82 statted in High-Tech is damn heavy, has a floating barrel and a pretty good muzzle-brake. Are lighter .50 BMG rifles harder to handle, resulting in higher Rcl and ST? Does not having a floating barrel and a muzzle brake translate into higher Rcl and ST? I'm also wondering if there is a realistic way to custom-build or even order a carbine length weapon (16" barrel or so) that is handy for entry but chambers a round substantially more effective against supernaturally tough threats than the 7.62x51mm. Semi-automatic, magazine-fed, at least 10-rounds. Ideal chamberings would be .408 CheyTac or .416 Barrett, if those can work in such short barrels, but otherwise anything that gets Dmg over 7d pi+. .450 Bushmaster looks pretty practical for a civilian monster hunter, though I don't know how much Dmg you would get. .45 Raptor might be even better.

it's 6d+1 pi+ Acc4 (it's basically the .50 "entry rifle" in Monster hunters - Champions). It's a shorter round then the BMG so doesn't make reach your 7d+ threshold though. Last edited by Tomsdad; 03-11-2016 at 06:58 AM. |

In the last twenty years, plenty of awesome-but-impractical rounds have been designed by wildcatters. At least some of them are designed to be compatible with AR-15 or AR-10 firearms, at least in part. Others have been MacGuyered somehow to work in other semi-automatic designs. And that makes them interesting to monster hunters, even if marginal or useless for real world tactical situations.

The RND 2500 in .408 CheyTac, Alexander Arms Ulfberht in .338 Lapua Magnum and CheyTac M400* in .408 CheyTac sound like interesting base weapons to apply modifiers to for an entry carbine suited for ST 13+ monster hunters facing supernatural horrors.
The VR1 rifle might also be worth looking into, though a 5-rd magazine is obviously not enough. *I don't think that one ever went into production, though.

This will reduce damage**, weight, acc and bulk (and increase ST and RcL if you remove the stock) *or Lapua / CheyTac rifle **huh but not range (personally I'd apply the same mod to range as damage) Last edited by Tomsdad; 03-11-2016 at 05:59 AM. |

For most firearms, reducing weight reduces required ST. Some firearms, however, are difficult to control and reducing weight actually ends up increasing required ST and/or Rcl. Using the rules without considering sanity-checking it against experience or education of other forumites can yield me a bullpup M82 that is Bulk -4, Acc 4 and does Dmg 9d pi+. It will weigh 30/4.4 after Weight Reduction and has ST 13 and Rcl 3. Now, I don't know if these are realistic numbers. I'm pretty sure weight could go down even more, because the M82 is massively heavy, even beyond what other .50 BMG rifles are, and we could probably dispense with some of that weight for an entry rifle. But I think that ST 13 and Rcl 3 are very optimistic numbers, especially if we do cut down weight further. It should certainly reduce Range as well.

Depends on what you want to do. Basically the short .50 bmg rifles are really not suitable for use as carbines, you need to use the rest.
As for building a suitable carbine doing more damage: .50 beowulf from loadouts monster hunters is a good candidate, but below the 7d (6d+1 pi+), but if you use the optional bigger is better rules it gets the nice x1.8 multiple, so that compensates.. .450 Bushmaster is lower energy and smaller cartridge(only 1.6x multiple with bigger is better) .45 Raptor is quite a lot higher energy, I wonder how well it can be shot without rest. But the damage profile would fit your criteria as it would be order of magnitude 7d+something of pi+ (though only 1.6x with bigger is better) In something like .408 CheyTac or .416 Barrett you are talking around 11kj of energy and that is a lot to shoot from anything except a rest and the rifles for such tend to be pretty heavy too... The heaviest cartridge I have shot from a short barrel is .338 lapua mag, and that is only about half the energy. An acquaintance has a shortened Sako TRG-42 and it shoots just fine without a rest and can be used well while standing. It is bolt lock though and still about 5kg, thus pretty heavy. A semiautomatic action would add further mass.. (The original short barrel TRG 42 model is 510mm (20"), but his is shortened close to the minimum allowed by law here, 400mm including the cartridge length, basically pretty close to half the barrel length of my long barrel version(690mm) and about 2/3 the original short barrel version.) TLDR; If you use the bigger is better rules just use the .50 beowulf, if not, use as high energy .46/.46 as you can with your ST. |

I don't reallly want a .50 pistol bullet that weights 300 grains to have a better Wound Channel Modifier than a 400 grain rifle bullet that happens to be chambered in .375 or a 510 grain rifle bullet that happens to be chambered in .458. *Because the ever-increasing linear WCM produced by his system does not play well with GURPS. If ST 14+ is going to be worth it, it helps if there are options for weaponry that really take advantage of the added bulk and strength.

Did the FN BAR come in anything that would get the Pi+ rating? Give it an extended magazine and that could be the way to go

Hang on thinking outside the box for a second how about adapting the Barrett M97 Dragonfang, .50 Browning from the High Tech designers notes?
You'll need to add the stock back on, but you could do that by reversing the process in TS (and factor in the stat line is based on one handed firing) That's a FA 12.7mm Acc 4*, assault carbine with a bulk of only -4*. It would be MinST14 (if I've factored two handed use and stock right). It will still be heavy, but I'm not sure why your worrying too much about the weight at ST14+. The range look's a touch high, but really it's not going to come up as you don't seem to be intending to fire this at long range anyway. *when you put the stock on Last edited by Tomsdad; 03-11-2016 at 08:08 AM. |
