I get that in 8" guns in sea mode sometimes too - nudge it one way a little and the gun keeps on traversing, nudge it back and it keeps going the other way. it vexes me. I am most vexed.
nope, it just happens sometimes. today in 8" I wasnt even adjusting fire and the gun traversed maybe 15deg, then back again to the exact same position. the cruiser was running straight, no maneuvering.
The Kanonenvogel had 6 rounds per pod, this is not even close to being open for debate.
