Maybe pressing F only activates half of the guns.
Try the letter B.
Hmm, I’ve never used B for anything in game that I can remember. I don’t believe I’ve remapped but just a handful of keys over the years. I fly more so what’s mapped to stick buttons is most important.
Anyhow I’ll have to try that but the keys I use most besides the most obvious = T/F12 (I mapped opposite of default) are N for fire all (only used this in bomber-gunner prior to the reason for this post) F for fire primary, Backspace for weapon toggle.
I suppose I should look into my key mapping…
In the past I’ve thought that Wirble barrels needed a cool down time if used continuously for too long, but I was told on country by several that in AH gun cooldown does NOT exist… So back to square one it seems atm.
