Title: Bnz convergence
Post by: Muzzy on January 28, 2014, 08:59:13 AM
Hers a question for the dedicated bnz crowd At what range do you usually take the shot, and what is your preferred convergence?

I'd set mine at 350.
Shooting at 600 and less.

Preferred range is an enemy bled dry of E at screen filling range. But I'm not a good shot.

I like 300, but I do most of my shooting at 300.  I used to set them at 350 but found that while I got a slightly better grouping at ridiculous range, at range I rarely knocked enough parts off to be worthwhile with .50s.  Shortening my convergence gave me a lot better killing power at the ranges I was doing most of my shooting.

Point 250

If you close fast, letting you get in short firing range, I think 300 or a bit less is best.  More than that and you start missing the 200 and in shots with the 50cal.  That's my take on that subject.

400-450 yards for me but depending on the angle of the bandit, I'll open up as far as 600 yards if the shot is there.

I do the same, in any plane.  Convergence is set to 200 for all planes, for all guns.

When I see the 400 yards turn to a 200 yards I pull the trigger.  My typical convergence depending on plane is usually between 350-400 yards.

As you can see from the variety of answers here, Muzzy, there really is no one "correct" answer to this.  Personal preference, skill level and aircraft types flown all come into play.

As a rule, it is best to fire in as close as you can, as you'll land more rounds and do more damage.  When setting convergence, I suggest thinking about: 1) the gun-package of that aircraft and 2) where YOU typically do YOUR most effective shooting.  By thinking in terms of "what works for me" instead of "what is correct", I think you'll be more comfortable experimenting and changing things as your gunnery skill level changes.

If you are looking for tips to get started, it may be more helpful to ask a more specific question, like:  "What is the best range for BnZ firing and convergence settings while in a (fill in the aircraft type)?" There will be different answers for the 109K4 or the P38-J or the P-51D, for example, because their gun-packages differ so much.  But then you will get specific information that may be more useful, especially for the aircraft you intend to use.

This thread has prompted me to review some films to answer the question that wasn't asked.  At range do you land hits?  At what range do you land the killing blow?

Thats one of the reasons I love watching other peoples films. I like to slow the film down when they go for a shot. It makes it easier to "see" the site picture they are looking for. When they fire, if you pause the film, you can see the range the target is at, and how much lead they are pulling for the shot. Slow mo shows if they hit at convergence or not so you can see the hows and wheres of their shots.

I have a horrible aim that I have been working on for a long time. I don't get to play often enough to burn the site pictures into my mind. But using this technique I have been able to get my hit percentage from under 2% to maintain it over 4% and I'm am now flirting with getting it to stay over 5%.

Practice is still king, but "how" you learn sure does help too!

Just a note: BnZ= Boom and Zoom!

My convergence is 275...get close...shoot...use speed to reset.

Convergence: 400-650 depending on gun package.
Firing range: 200-1000
Ideal firing range:  400-600
Hit%:  Typically 12-14%
Killing range: Up to 1000 but mostly under 800

What I lack in ACM I make up for in SA and gunnery.

If this is a gunnery question concerning BnZ, and you are attempting to find a sweet spot convergence to solve the three primary problems affecting high speed gunnery. Then consider Hitech has modeled gunnery historically. Even if we want to stretch the physical limits. Shooting down other small fast fighters, your effective maximum range is 1200ft. Even with cannon rounds. Yes the chemical content increases their range. Longer range decreases their odds of hitting anything as small and fast as a fighter.

In ww2 average convergence for wing mounted guns was 250-333. HUB cannon were stuck at 0 incidence, and planes like P38 and mossi were harmonized with the sight line to drop back into it at about 1600ft. Past 1200ft, dispersion makes hitting a tiny fast fighter less probable as a full time tactic. Bombers are another discussion. Even then a 50cal slows down by 2\3 and looses half its kinetic energy by 1200ft. After 1200ft where it drops 4ft, it begins dropping through the basement and dispersed. So in P38 the ganging of the 50cal allowed it to reach out to 1600ft but, you are still loosing kinetic energy badly in terms of penetrating armor. The same problem will exist for a 20mm AP and you will start getting more skin surface detonations than internal after penetration. Wonder if Hitech has a formula that accounts for 20mm lack of penetration past 1200ft on a graduated line? You see as many ww2 bomber damage photos where it's obvious the cannon round exploded after penetration as you see explosions where the aluminum skin was warped and curled up.

In ww2, guns were harmonized to the effective combat range of the round used. Since Hitech reasonably models this in the game. I would venture the OP is having a gunnery problem related to firing from a higher position down, and the aimpoint. Calculating lead and deflection for the target as it turns under his down pointing nose. And accounting for the effect of his increased speed in the dive on where his rounds will really end up.

After action reports and film, showed the vast majority of kills were made at, or inside of 1200ft on both sides of the conflict. Bombers by the virtue of their size and slow speed are another discussion. Including how slow average bomber combat speeds were opposed to ours in the game. Still, surface area counts as your rounds disperse wider past 1200ft.

Bustr good information.

The other day a brewster knocked my P47M out with a few pings and he was 1800 ft back.  They have amazing firepower.  I don't think F=MA works on them.

300 but some planes are different. P38s and planes with big cannon in the nose more like 400 to 600. When we had F3 I used to set the NS37s of IL2s to 250 but not set them to 350 cause the vertical is harder to use.

Bustr, I did go back in and change my P38 convergence after reading your post.  I spent some time in the offline area with the target to confirm it is a good setting.  Thanks again.
