@GrafZeppelin1936 My apologies, I did not see your comment until now, the mod development has been halted as I am not funding the project anymore, however other people are working on their own solutions, please check Mx Redux mod, it comes with 20 rounders.

Further to my last: I downloaded the mod to a separate file. Still broken. Not sure if it broke with 2.18 or not.

This mod no longer works, at least for me. I had a saved loadout and when I selected it in the Virtual Arsenal, it was showing as missing. It's still in my loaded mods list and I can still comment on this page, which is interesting and probably doesn't mean that it's been taken down.

@Whells Hi, are you the Reddit user TheWhells? I found your post about your 20&10rd MX mags mod on r/arma channel. I'm looking for a replacement for the ugly standard long mags for a long time. When will you release your mod? Thank you.

@Whells go ahead. Just credit me and would you link it too? I'd like to check it out

Hey, would it be okay to use this mod as part of a mod that adds more mags to the Vanilla MX, ie 10, 20rd mags?
Rooster  [author] Dec 2, 2022 @ 8:02pm 
I concluded that the vanilla round was a 123gr round at 920 m/s out of the MXM. That is my reference round. I set the MX rifles in this mod to lose velocity based on barrel length. Looking at Load data online, only a Creedmoor could reach that. I originally based these speeds on the Grendel, a cartridge I personally use. It makes more sense to me now, especially with the recent adoption of the high pressure 6.8x51 cartridge, to use a larger cartridge and opt for higher velocity. So, I am aiming for over 3000 fps for the GPC Mk 2. I will keep the 107gr projectile. It seems to be the best balance of BC and speed according to my calculations.

see my work so far...

By the way I almost started working on the assumption of the 6.5 creedmore. You will want to use the 6.5 grendel. It seems as though the vanilla 100rnd mag uses an initSpeed of the 90gr at 2880 fps yet the vanilla 30rnd mag uses the ballistics of the 123gr at 2650 fps. I still have yet to be able to convert ballistic coefficients and sectional density to the airFriction and caliber values in the vanilla coding.

Thanks @Rooster!

@pvt TOAST, The calculator is here. I am picking this back up to redo the ballistics. More towards the 6.5 Creedmoor ballistics.

Spartan0536 is the one to ask. I can't recall the calculator
pvt TOAST Sep 30, 2022 @ 11:10am 
Where is this calculator? I found the math in the BI forums, and some of it does/doesn't make sense. My only obstacle is to convert ballistic coeff and sectional density to the cfgAmmo parameters (which shouldn't be that hard to do). Once I have the ability to convert those numbers, trajectories will be awesomely accurate, and I can focus on damage and penetration.
Rooster  [author] Sep 30, 2022 @ 6:58am 
I used a calculator created by Spartan0536. They can help you But you would have issues getting it to work as you intend. Body armor is more or less just a bonus to HP. Currently, the SPC is best against infantry because of this. Penetration in the configs is specifically for barriers.
pvt TOAST Sep 29, 2022 @ 4:17pm 
you know what, based on how cleanly you wrote this mod, I can make (virtually) any type of 6.5 round possible. A super heayweight (+160gr) subsonic load is very possible. I wont be able to make the actual rifle though because that needs 3D modeling software, which I haven't had/used/seen since college. The main challenge in making new cfgAmmo types is making sure they penetrate/stop according to what they hit. A heavyweight subsonic would be stopped by your plate carrier, but would probably induce a ton of camera shake, as well as not being heard from very far...pretty sure I can accomplish this. The only question I have is, what is the math behind matching ballistic coeff with Arma's airFriction? Does anyone have a benchmark measurement for this?
Rooster  [author] Sep 28, 2022 @ 7:19pm 
@pvt TOAST thank you! Glad you like it! I need to get back into Arma
pvt TOAST Sep 28, 2022 @ 11:07am 
@Rooster, just downloaded and tried. Very well done! I have been looking for a mod similar to this as I typically carry 2 different loads to the range based on what I want to do.... this makes me wish I was a programmer so I can make the "handloaders bench" mod where we can choose projectiel type/weight/charge etc...
Rooster  [author] May 20, 2022 @ 1:17am 
@ToGG You are more than welcome to try
Rooster  [author] May 16, 2022 @ 4:50pm 
@ToGG I am not aware of anyone working on it. It will not work with ACE. How to make it compatible? I honestly don't know. I learned to mess with configs to make this. Learning how to make it ACE compatible was my next step but you know, life happens.
ToGG May 16, 2022 @ 4:43pm 
@itsDIETZ

Do you know if anyone is working on an ACE version? What about this wouldn't work with ACE?
Rooster  [author] Apr 26, 2022 @ 3:26pm 
They're caseless cartridges. I don't have the modeling experience to do that, either way.
Ares. Apr 26, 2022 @ 12:02pm 
hello, sorry for disturb, can you add the ejection case from the mx magazines? please, will be awesome , thank you in advance
Rooster  [author] Nov 5, 2021 @ 2:39pm 
@ToGG There's no reason it shouldn't still work. I never got around to making it ACE compatible but otherwise, it should still be fine. I don't have anything I could really add to it.

If anyone wants to make it ACE compatible, go for it. Just credit me.

@itsDIETZ

Really sad to see this mod isn't still alive. Looks like the only MX mod that actually makes it feel like the round is supposed to be

@[CN]Tie.southerncross thanks! Hope you enjoy it!

looking forward to the ace compatible version with wishlist items come true nice work
宇治登山协会 Aug 27, 2019 @ 11:53pm 
got it
Rooster  [author] Aug 27, 2019 @ 9:44am 
@[CN]Tie.southerncross You can find the ammo in the Virtual Arsenal when not using ACE.
Rooster  [author] Aug 27, 2019 @ 9:43am 
@[CN]Tie.southerncross This mod isn't ace compatible yet. I plan on doing it eventually. I've got to learn how ACE works first and find the time.
宇治登山协会 Aug 23, 2019 @ 5:25am 
where can the new ammo type be found for I can't find them in the ace arsenal
Rooster  [author] Aug 9, 2019 @ 5:56pm 
@puffy696 thanks, Puff!

Great Work
Rooster  [author] Jul 8, 2019 @ 10:02pm 
I'll be releasing the SPC hopefully at some point soon. I have it done, I just have to find the time.

@V. Berlioz Thanks!
