I will keep that in mind. But the idea behind the persistent zero feature is, that you do not lose your (custom) zero setting, when you restart the game.

I have published the configuration data in the first post of the AdvancedBallistics thread ("Ammunition database" and "Weapon Database").

What types of ammunition, exactly? I think the best solution would be to reworked the zero system of vehicle mounted weapons.---------- Post added at 18:17 ---------- Previous post was at 17:58 ---------- I added a ammunition and weapons database to the main post of this thread. Let me know if this is good enough.

That would also be my suggestion. It would simplify the work of a 3rd party developer, who wants to support AdvancedBallistics, by a great deal. The bullet velocities differ at long ranges, due to the different drag model. This does affect the terminal ballistics, but not adversely. That is exactly what AdvancedBallistics does. It will get you proper ballistics for all vanilla small arms and 3rd party small arms that support it.Play withSIX link: http://play.withsix.com/arma-3/mods/gpXxpWsd5BGZ2gAVF72WTA/Advanced-Ballistics ---------- Post added at 17:25 ---------- Previous post was at 17:00 ---------- By far the most important parameter is the ballistic coefficient. All other parameters (bullet caliber, bullet length, bullet mass, gun powder temperature effect on muzzle velocity, barrel length, ...) are nice to have, but much less significant and optional. Providing bullet caliber, bullet length, barrel length, and twist rate data is optional. A stability factor of 1.5 is used, when you leave any of them empty. This is how it works in vanilla ArmA III: Ammo config: airFriction - BC counterpart caliber - penetration factor compared to 7.62 NATO hit - stopping power typicalSpeed - minimum velocity with full stopping power (e.g. 750 m/s for M855) Magazine config: initSpeed - muzzle velocity This is how it works in AdvancedBallistics: Ammo config: caliber - penetration factor compared to 7.62 NATO hit - stopping power typicalSpeed - minimum velocity with full stopping power (e.g. 750 m/s for M855) AB_caliber - bullet caliber in inches AB_bulletLength - bullet length in inches AB_bulletMass - bullet mass in grains AB_ammoTempMuzzleVelocityData[] - array of muzzle velocity shifts in m/s with 11 data points from -15 °C to 35 °C (example: {-26.55, -25.47, -22.85, -20.12, -16.98, -12.80, -7.64, -1.53, 5.96, 15.17, 26.19} AB_ballisticCoefficients - array of ballistic coefficients (contains one element more than the velocity boundary array) AB_velocityBoundaries - array of velocity boundaries AB_standardAtmosphere - "ASM" or "ICAO" AB_dragModel - Number that specifies the drag model [1, 2, 5, 6, 7, 8] AB_muzzleVelocities - array of muzzle velocities (same size as barrel length array) AB_barrelLengths - array of barrel lengths (same size as muzzle velocity array) Weapon config: AB_barrelTwist - barrel twist rate in inches AB_twistDirection - direction of twist (-1 = left, 0 = no rifling, 1 = right) AB_barrelLength - barrel length in inches

You can use any mission from the 360 Degree Training Course pack to measure bullet velocities by shooting steel targets. Then you modify the BC until the trajectory matches (the range cards remaining velocity output equals the measured velocity for a given distance).

Version 2.3 Changelog -Added a scope zero adjustment (adjustable point of impact with elevation being 0 mil) -Added more ammo configs (Mk318, 7N6M, 7T3M, 7N14, 7T2, 57-N-231-P, 57-N-181-S, .32 ACP) -Fixed another bug in the muzzle velocity calculation (was only present for some ammo types) The default key combination for the zero adjustment is CTRL+SHIFT+UP/DOWN.

I will try to, but I can't promise that it will become better. Suggestions of how to implement it, are welcome. I will do that, it was planned anyways. I watched it some time ago.

Yes, I am a fan of TiborasaurusRex ;). HighRes: mirage_real.mp4

I have just created a ballistics table for the .408 CheyTac / CheyTac Intervention combination: .408 CheyTac - scribd - docdroid - zippyshare (mind the reference barometric pressure (station pressure) of 1013.25 hPA) This was done by combining output data from JBM Ballistics with an xls template from TiborasaurusRex. ---------- Post added at 15:36 ---------- Previous post was at 15:23 ---------- I don't know much about it either, but you will find some basic information here: https://community.bistudio.com/wiki/ArsenalIt looks like this, once you opened it:

@vekongmaster, did you try using the virtual arsenal feature that comes with LEA? "Apply loadout" -> VA

I tried to make sure that everything works like you would expect, but I did not pay particular attention to the issue you mentioned. The modified packs however, require AdvancedBallistics or it will not work. ---------- Post added at 08:48 ---------- Previous post was at 08:30 ---------- I will pay attention to the weapon <-> magazine dependencies when I update Trixie's configs the next time.

ATragMX v0.9 introduced user editable gun profiles. They are stored in the profileNamespace. You can create new profiles by doing the following: Open the GunList Click "Add New Gun" Enter a profile name Click "OK" Select your newly created gun profile Click "Open Gun" Enter BH, BW, C1, MV and ZR Press 'Enter' while your cursor is in the ZR input Open the GunList again Select the newly created gun profile Click "Save Gun" ---------- Post added at 19:45 ---------- Previous post was at 19:26 ---------- AB_338_Ball represents Sierra, 0.388 cal, 300gr, HPBT MatchKing Using a ballistic coefficient (C1 in the ATrag) of 0.760 will get you pretty close.

I removed the download links in my previous post, sorry for posting them publicly. I will send them as PM. The new config entries only provide additional data about the weapons and ammunition. They have no effect unless used together with a mod like AdvancedBallistics, that utilizes them. Existing config data does not need to be modified at all.When used without such a mod you have no advantages and no disadvantages.

Version 2.2 Changelog: -Fixed a minor bug in the muzzle velocity calculation (sometimes caused RPT errors) -Refined and expanded the ammo config (added .303 British, Mk318 and Russian M43) -Userconfig setting AB_VEHICLE_GUNNER_ENABLED is now true by default ---------- Post added at 16:20 ---------- Previous post was at 16:10 ---------- Players who use Trixie's weapon packs might be interested in the following pack of config data. Trixie.zip The config.bin files contained in this pack can be used to replace the original ones in Trixie's weapon packs. You can use PBO Manager to do that. Or - if you don't mind the big files - just download the whole (modified) packs: @trixie_britishweapons @trixie_recon @trixie_rifles @trixie_xm8

Sounds great.I've created a new version of your config file. All ammo, magazine and weapon classes are extended to fully support AdvancedBallistics. Edit: Links to modified config files as PM

Hello EricJ, have you ever stumbled across the Advanced Ballistics mod? To make the most out of your mod, when used together with this addon, you would have to slightly expand your config file. Only minimal effort is required. I - and surely some others - would be very happy if you do so.

Yes, but only if your have set your reference heading correctly and are facing the wind while you measure.The WIND SPD page always outputs the effective wind speed from the direction you are looking at. The CROSSWIND page outputs the crosswind relative to your reference heading (target direction). The HEADWIND page outputs the headwind relative to your reference heading (target direction). You can set your reference heading by clicking the center button on the cross- or headwind page. Your wind speed reading will be incorrect unless you measure directly into the wind. Obstacles (houses, walls, stones, trees), sloped terrain and height above ground also affects your measurement.

I do not have appropriate data for the russian .50 Cal cartridge, that is why the B_127x108_Ball class is incomplete.

For muzzle velocities around 865 m/s: [-26.55, -25.47, -22.85, -20.12, -16.98, -12.80, -7.64, -1.53, 5.96, 15.17, 26.19] - MV shift in m/s from -15 °C to 35 °C For muzzle velocities around 900 m/s: [-27.20, -26.44, -23.76, -21.00, -17.54, -13.10, -7.95, -1.62, 6.24, 15.48, 27.75] - MV shift in m/s from -15 °C to 35 °C

Thank you very much for spending your time on testing this. I was able to reproduce the bug. Will be fixed in the next version. Great news. Yes that's intended. The bullet trace is only visible when the bullet is flying faster than 600 m/s. This might lead to a misconception of the trajectory. Great news. ---------- Post added at 09:12 ---------- Previous post was at 09:08 ---------- Yes, I will change it in the version. ---------- Post added at 11:00 ---------- Previous post was at 09:08 ---------- Version 2.1 Changelog: -Fixed newly introduced advanced ballistics for rounds fired from vehicles not working on multiplayer clients -Fixed config setting AB_DISABLED_IN_FULL_AUTO_MODE not working correctly for burst- and custom fire modes -The muzzle velocity shift array (AB_ammoTempMuzzleVelocityShifts) is now using SI units

The muzzle velocity shift is currently the same for all rifle calibers. Velocity shift in feet/s from 0 °F to 100 °F in 10 °F steps: [-91, -86, -78, -68, -57, -42, -23, 0, 29, 65, 110] The muzzle velocity can also be affected by using muzzle accessories like suppressors and varies with barrel length. Here is the config data used in AdvancedBallistics v2.0: http://pastebin.com/0ZFei8QU Suggestions for improvements are welcome.

What does the error message say?

I have not yet managed to reproduce the problems mentioned above. I am using CBA_A3_RC3 v1.0.8.140725 (downloaded via Play withSIX) on the stable branch (latest version) with a fresh game profile. @Ninjaman666, hellsan631, CosmiC10R, maybe your profileNamespace is corrupt. Creating a new game profile might fix your problems. Edit: I just tested it on the development branch - no errors.

Lack of poper sight adjustment capabilities. Not yet thoroughly tested - and yes, it might cause frame drops if you have multiple vehicles firing simultaneously.

You need to press 'Enter' after you modified the zero range, while the cursor is in the zero range input field.---------- Post added at 13:55 ---------- Previous post was at 13:53 ---------- @hellsan631, does it work if you play in singleplayer (Campain, Editor, ...)? @CosmiC10R, are the AdvancedBallistics hotkeys working (SHIFT+K, ...)?
