Convergence

[Butcher]

Don't you mean the Yak-9T?  The 37mm on the P-39 drops like a meteor.

D200-D225 for 37MM on Yak-9T and P-39 has been favorable for me

D250 for 109K4 works, heard some have it at 200-300.

I might have them mixed up, don't fly either that much.

If you set any motor cannon to 200 then fly offline at a level steady speed of about 250ta at the offline target. You will be surprised how littel drop there is in the ShVAK20mm, MG151/20, MK108/30mm, M4-37 and NS-37 between 200-400. About 5Mil average.

The ballistic issues many players experience with the MK108 and M4 are due to their slow initial velocity from the barrel which translates into a slow time to target. Many forget that the round is slowing down as it travels. With the 30mm and M4 from 0-200 you are firing dead on to a 2-3Mil dispersion/drop and 200 to 400 your ballistic drop is about 5-10Mil dispersion and 10Mil. By 400 the 30mm and M4 have dropped about 12 feet. After 400 both are worthless for air to air shooting becasue of the drastic dropoff to 600 and increasing time to target. By 600 the MK108 is down to 370m/sec. You will notice offline at 400 all of these 20-37mm cannon have abismal dispersion which limits their effective range to under 400.

Over the years there are always a few dedicated players who spend the prodigious amount of time to learn the drop and lead timing for these kinds of big guns MK108 & M4. Or have a natural affinity for them. They are the exception not the rule. But, will probably chime in here anyway as though they are the normative player group. Shooting takes the time to practice.

MG151/20.......720m/s
ShVAK 20mm...770m/s
Mk108 30mm...500m/s
M4-37mm........610m/s
NS-37 37mm....900m/s

If the NS-37 which had a short stroke action, is modeled correctly in the Yak9T, then a 735gHE projectile at 900M/sec, recoil induced dispersion should make hitting anything with it past 3 round bursts problematic to near impossible.

Bustr whats a  ballistic?

















dood you know I couldnt contain it!!

Ballistic:

It's that snakey lizardy thing that petrifies you with it's gaze. Remember Harry Potter and the "Chamber of Secrets"? Well in this game it petrifies you with it's slowness and most of the time is so near sighted it misses you. Then you recover after it passes by you.

Isn't that a basilisk from like greek mythology aswell? Whats the connection in name? And I never read/watched Harry potter. Seriously tho bustr may be really "in depth" but if  you read his wall of text it does  help alot. I know he's helped my gunnery alot and I haven't even applied all his teachings or techniques.

I would agree that it's all about "feeling" the round, I guess I played with taters too much that now I'm used to it. As long as they're not making erratic movements past d400, I can land a hit within 2-3 tracers shells. I switched over from the K4 to a P39Q the other day and had a MUCH more successful time with landing hits. Perhaps it was the 1 bullet = 1 tracer that helped me, but I played around against CV planes and knocked them out of the sky D400+ away. The M4 is slightly faster and maybe that's why, but IMO, the tracers helped a lot more.

Dood here I thought this was a Harry Potter thread....dern and I like ballistics the way they slither on the ground and hiss and give that stink eye.

When I hear the word ballistic I think of Mythbusters' ballistic gel projects..

Convergence settings are overrated imo.

Convergence settings are overrated imo.

I used to agree, and if you mean in terms of small changes like say, point convergence at 325 versus 300, I agree completely.

However recently I thought I'd experiment a bit and shortened my convergence on my .50 cals from 450 to 300.  I had it at 450 in case I wanted to reach out to 800-1000 to get someone to turn and felt the damage was good enough in closer.  I wanted the ability to have best accuracy and damage as they're pulling away from me at 400 icon.

The reason I brought the convergence in is I've found myself lately not doing any shooting outside of icon 600 because I've come to the realization the .50s out there haven't got near the punch they do in close, and unless you're getting a newish guy to turn, it's not worth wasting the bullets.

I have always done most of my shooting in between 400 and 200 icon.  My ability to hit hasn't changed in my opinion, but subjectively it feels like when I hit something now, I am way more likely to knock something off.  Snapshots feel like they work much better now too.

I believe the explanation for this is that it's on wing mounted .50s, the type of gun setup that benefits the most from hitting at convergence versus all other gun setups.  If I flew nose mounted stuff primarily I doubt the difference would be as noticable.

I believe the answer for convergence is truly 'where you do most of your shooting at.'

  This is what I usually suggest,then explain how the icon counter works. When the icon changes to D200 the plane is actually about 300 yards away. Personally I keep my convergences in close,275 would be the furthest out I set any gun and like to see D0 before I shoot!

I have the convergence for my f4u 50.s set at 325. And I can still aim and make parts come off at 800 range if I just make the correct lead and get about 1sec burst in at one spot. If I follow someone that is attempting to rope me and he's 800 above me like a big cross in the sky, I just aim a good plane length infront of him while I give him that 1sec burst. If the burst hits a wing the wing will come off.
I have seen ailerons and elevators come off, and fuel leak at 1000 range with my convergence set at 325. But once the range icon turns to 1k it is pointless to waste more ammo, atleast that is my experience.
So even if I might do a bit more damage further out with higher convergence, I don't see the point. The way I fight I usually fire at 200-400, the long range shots I only use to show some that they are not necessarily safe at 800 range from me if it is obvious that they are believing that..

Don't you fly through alot of debree doing that, D0.. ?? 
I have to try that.. If I can restrain myself to hold fire that long that is..
