Author Topic: Question about gun harmonization (Read 1965 times)

Did some checking, turns out was doing a simple estimator for the amount of bullet drop when setting up the harmonization. This had the net effect of bullets shooting about a foot low on the fw at 550 yards. Change it to a more precise method and turn off bullet dispersion to see the results.

Here they are, they match mandobles table.

Note made a typo on the image convergance was 550.

Redid the tests again (190A5 inner guns only at 330mph). 150 and 200 yards target rounds hitting clearly lower than GS center, at 500 yards all the hits vertically near the center. Is dispersion putting the rounds lower most of the time?

How does default forward head position play a roll in all of this if any? meaning if someone accidently moved their forward looking head position and saved it or got it just a bit off, but to where you still saw the bore sight good....would this cause 2 people to see 2 different views? I mean you have already set your convergence in the hangar, but have you set your head position for the convergence of the guns?

or tested to make sure they are passing the center bullseye of your gunsight....

or does this not matter?

( tell me to shut up and go crawl under my rock if all this means nothing

Like I said mand, current method shoots about a foot low.

HiTech, 1 feet too low from where? gunsight? expected flight path of the rounds? With dispersion? Without dispersion?

All I can say is that the german pattern shows an elevation of 2.6 feet above gunsight line from 300m to 400m, 1.3 feet above GS center at 480 yards, 0 at 550m. There are two intersections of the gunsight line: 120m and 550m.

Of course I cant turn off dispersion but every bullet concentration point is below or near gunsight center with 550 yards as convergence. May be I'm performing the tests wrong but what I expected, even with dispersion, is having all the bullet concentration above the GS line from 120 to, at least, 450m (taking into considertion that the target is keeping your speed and flying away your firing position).

Mand: Wake up, im agreeing with what you are seeing, the picture is after I made a change today for the next patch.

Thanks HiTech for agreeing to take the time to fix it. And thanks Mandoble for taking the time to bring it up without p-ing anyone off
