How do BF and RF play out for UAC, LBX and Rifle?

Greenhorn pilot reporting in!

I've familiarized myself with the different AC types by now. AC5-BF seems just universally good until you get UAC5s, RF AC2 is a meme. Any RF will incur a serious ammo weight added on. Less experience with AC20, but AC20 BF feels deadly.

But how do BF and RF work for the other ballistic types I haven't found (m)any of yet? I have one BF UAC and that thing just doubles the already considerable UAC dispersion. I haven't got a RF UAC yet, but isn't that a bit redundant and overdoing it?

Similar question about LBX, how does the burst shot or slug interact with BF and RF.

Rifle seems pretty straight forward, RF eats ammo and gets real spicy, BF feels good even with the added spread. Am I missing anything else here?

No YAML, just vanilla weaponry.
