Michael, are you seriously suggesting that you pull the trigger once, wait until bullet #1 and #2 automatically left the muzzle before you swing the gun 180 degrees and align it with a second target (in less than 0.07 seconds!!) before bullet #3 and #4 automatically leave the muzzle - with no risk at all of hitting any other target in between...?
I would
love to see a video clip of that ;-)
The
only way that you can realistically hit two different targets (that can be 180 degrees and hundreds of meters apart) in the context of the rules as they are written is if the gun is actually just firing 2 bullets each time you pull the trigger.
For narrow burst you pull the trigger twice for a burst of 4 bullets and for wide burst you aim at one target, pull the trigger once (resolved as one SA burst of 2 bullets), then you spend that extra minor action to quickly realign your aim to a second distinct target and then you pull the trigger a second time (resolved as another SA burst of 2 bullets).
This is well supported by the rules as written (and also similar to how Long Burst was resolved in SR5).
In order for wide burst to make sense if you actually fire 4 bullets when you pull the trigger once (but now we are talking true 'spray n pray' rather than aiming at two different distinct targets) is if...
...either both targets get additional restrictions
(for example:
"Must be within 2 meters of each other with no other targets (friend or foe) in between")
...or perhaps that you treat it as a true frontal cone AoE attack that have a chance to hit both friend and foe
(for example:
"A triangular area projecting from the shooting character outward up to a distance of his choosing with a width of 2 meters at its end and a height of 1 meter").
Either way you would need to create house rules if you rule that it automatically spit out 4 bullets each time you pull the trigger (which is an indication that you either read the rules incorrectly - or perhaps that the rule as written is incorrect and is currently subject of errata).
It also says BF mode fires multiple bullets with a single pull, and uses 4 bullets to either do a narrow burst on 1 target, or a wide burst on 2.
While book mention that burst fire automatically fire more than one bullet each time you pull the trigger and that an attack in burst firing mode will always consume a total of 4 bullets, the book does not mention if you pull the trigger once or twice or if each trigger pull automatically fire 2 or 4 bullets. Both readings are within the context of the rules as they are written.
The only difference is that one reading explain how you can realistically hit two different distinct targets that are 180 degrees and hundreds of meters apart, while the other does not.
For what it's worth; If Wide Burst (as currently written) had not been an option then I would have agreed with you that a weapon in BF mode automatically spit out 4 bullets each time you pull the trigger.
Yet the AR-penalty is effectively split over the two attacks, since a wide burst is handled as 2 -2AR/+1DMG attacks.
I am pretty sure RAI is that firing in Burst Firing mode (Narrow Burst or Wide Burst) reduce your Attack Rating by 4 (since you have to handle the recoil of 4 bullets) and for Wide Burst you then compare your Attack Rating with the highest Defense Rating of the two targets. This would also be more clean and a lot less confusing when you later also mix in things that provide recoil compensation.
But because of wording, your Attack Rating is currently reduced by 4 when firing your 4 bullets at one target, but only reduced by 2 when you fire your 4 bullets against two different distinct targets. It does not make sense that your attack rating should be reduced less when attacking two targets (as with burst firing mode you still need to manage the recoil of 4 bullets rather than 2 bullets as if you used a semi automatic weapon to double tap a single target). But I agree with you that this is RAW (subject for errata?)
