Bazooka Range seems like shit at first since it doesn't even affect the Elite Bazookas (it only affects the standard ones), and only grants a measly 5% range increase at that (for a total of 36.75 range, 35*1.05), but because of how the range stats work with bazooka, to my knowledge it will also essentially increase the accuracy and penetration of the bazooka all the way out to its new max range (albeit by a factor of only 5% still), which could conceivably come in handy. It also makes it a little easier to kill vehicles trying to escape, but the bazooka is trash at killing stuff anyway so meh.
I don't know the bulletin in the attribute editor, but range increase does not necessarily also increase the accuracy. In the editor, there is a "far range" and a "max range" attribute. For most weapons the variables have the same value, but from my understanding if the max range is greater than the far range, accuracy etc will be the same as far range.
Long story short:
I assume that you only get a accuracy buff if the bulletin modifies the far range. If it modifies the max range, probably not. I have not tested this, just my thoughts. Testing it would also be a huge pain in the ass.
