If you're counting Assault Cannon rounds as explosives (stated to be a "highly stable explosive rounds") for the purpose of barriers, then the Sniper Rifle could just be loaded with Explosive rounds or EX-Explosive rounds and do the same thing. They use the same terminology. As for Guass Cannons, they fire a dart, which is going to fall under "projectile" or "bullet" for DV purposes.

You could argue it doesn't count as an "explosive," but it sure isn't a "bullet" or "projectile" either so it would just do base damage. I'd also have no problem with Explosive/Ex-Explosive rounds counting as both a bullet and an explosive and thus doing 2 DV x 2 for 4 DV.

Explosive Round and Assault Cannon rounds both explode.

Exploding tends to happen at the last point the projectile remains a coherent whole.

They both explode on impact. I'm not seeing where you're going.

According to the terminology of the book it's just as much a bullet as any other firearm ammunition. Just really big ones. They should follow the same rules according to RAW. It shouldn't, but it does. They didn't give it any blast effect.

I've read somewhere in one of the books that if you use a sniper rifle (or at least some sniper rifles) without setting them up, you get penalties.  which is normal, as those weapons aren't designed to run around with.  It has something to do with barrels getting out of line.

[WellsIDidIt]

In all reality most combat ready ones are designed to be taken on the battlefield as you climb, crawl, and sprint your way to where you need to set up. I really really hate the edge test. I assume it's a test to see if you've knocked the optics out of line, but you could always case them, assuming you're even using gun mounted optics in the smartlink and goggle magnification era.

Depends on the weapon system. One that is hardened and made for you to run around with will be more in line with a semi-automatic battle rifle. A more classic sniper, like a bolt action anything, you can actually jack up the sights and barrel alignment fairly easily. In real life there is pro's and con's to each, which don't translate well to Shadowrun (recoil comp is a great example of this IMO).

@Ted: I believe SR should get a large portion of their damage from being able to shoot vital points whereas a AC can hit someone anywhere and hit like a truck. If you're strong enough to carry an AC, you should be fine. It's not a precision based weapon. A sniper rifle imo would be longer than an AC, making it fairly unwieldy in combat. That's why a lot of SR come with bipods, because they're meant to be stationary while firing.

Well, on the length question, the most famous Assault Cannon I can remember actually seeing in a movie was the Cobra Assault Cannon from Robo Cop, which is a Barret M-82 Rifle with some "dressings". I have a hard time seeing an Assault Cannon being smaller than a Sniper Rifle and being drastically larger caliber.

Here is a ww2 version of an assault cannon for your viewing pleasure. I'd hate to be the guy carrying that around. if you get hit by this anywhere you are dead. it is made to take out armored vehicles and IMO is not even close to a sniper rifle in almost any way. I assume in 2072 they figured a way to slim the package a bit and improve the overall weapon; add magazines, etc. But I agree sniperrifles should not do the same damage as something like this.all the specs can be found here: http://www.ma-rooned.com/2011/02/friday-gun-pr0n-200.html

It seems like a Sniper Rifle should have a lower base damage code, but get extra bonuses to hit when stationary, prone, aiming, etc, which translates to more successes, which translates to greater actual damage due to better accuracy.  If not being used to snipe, it should do the same damage as an assault rifle or the like.

That said, now I want to make a Troll sniper that uses an Assault Cannon.  I wonder if I can get a silencer for it? 

[Mäx]

But I agree sniperrifles should not do the same damage as something like this.

No they shouldn't and they don't, thats a recoilless rifle not an assault cannon, those are not even close the same think.

Max beat me to it. And is correct.
There is no way in heck a Human (or troll or whatever) carries an 80mm weapon. 20mm is a stretch. A .50 cal is 12.7mm. Assuming awesome RC maybe 20mm is feasible. The .50 cal I shot hurt my shoulder with a shock pad. Anyone claiming an 80mm weapon is able to be carried is insane. And I do mean carried, at all, commit yourself to an asylum if you think someone can fire it standing.

20 mm is not a stretch. here 60 years in the past (sr4 calendar of course) the Barrett xm109 is delivering a 25 mm round from a rifle with a 5 round magazine. where the panther XXl says it delivers small tank rounds (which admittedly is 25 mm, if by small tank they are talking about the recently retired bradly). however the weapon that I previously posted is specifically meant to take out armored vehicles as is stated in the panther's description. These WW2 weapons (or weapons of this type) were typically 3 man carries (and that is still brutal). but  with 2072's current state of technology im sure the package has been reduced.

Although perhaps you could consider the XM108 an assault cannon in which case the round is still twice as big as a barrett 50 cal and has a ridiculous velocity and could not be even considered in the same category as a m14 or remmington 700. the .308 and 30-06 being the most common sniper rounds. I dont think that will cange much in 60 years. since it hasn't in the last 60...

@ max search for assault cannon. you will find a lot of sci-fi bs, mostly Gatling guns, this recoiless rifle is the closest thing to an anti tank "gun" that one person can shoot, which fires small tank rounds. the current M1 Abrams fires a 120mm round. so a 57mm round is "small" in comparrison.

While agree with your words, fitz, I wholly disagree with a one man carry 57mm weapon. Although, maybe I am shortsighted, 70 years ago no one thought a 370 MT nuclear bomb was possible. However, I have a large amount of physics knowledge, and I can not think of a possibility where one guy can shoot an 80mm weapon.

I'd usually assume troll with a gyromount.
