I used the A19 south battery to test.
Leaving the gun straight out.
0.6 - 30.7 range would explode leaving the gun.
30.8+ would work.
Then when I tried to test it again, all of the rounds exploded leaving the gun no matter what the range.
On another test, 0.6 range worked when pointed extreme left (tip of land), straight out, and extreme right (I saw the shots land). When I tried 0.6 later, none of the rounds worked.
I went to tower and back to the sb and tried the tests again but I couldn't get a shot off.
Before I did my 'controlled' test I know I was getting some shots off between 0.6 and 5.0 but since I wasn't keeping track at the time I don't have good info on that.
I was using F3 view. I couldn't find a rhyme or reason to why they exploded.
