Object 775 BUR

The BUR HE ammo, I noticed that it sometimes flys just nicely, and at other times it drops like a stone. Why is this?
In other words, what made it fly in ok way?

Are you getting a message along the lines of “line of sight to missile obstructed?”

the HE round in the 775 isnt a missile just a rocket assisted round so that shouldnt happen

“line of sight to missile obstructed"

Not sure, I’ll check when I take it for a test.

Thank you
