Gas expansion has limits, that is to say even with an infinite amount of powder available you are never going to get fps higher than a certain point.  Obviously different chemical compositions will have different rates of expansion.  Further, while yes, many rounds are made with less than 'maximum' effective powder, there is still a limit to how much you can squeeze in for added power and still fit into the case. Most Wildcatters expirement with larger casings, necessitating using different mechanisms.

Your half right with your criticism here. There are a wide range of powders availible to loaders today, all with varying burn rates. Its not uncommon for loaders to 'tune' ammo to a particular weapon by trying different types and quantities of powders.

For example, I own two different .45's, one with a 5 inch barrel, and the other with a 3 inch barrel. I use different ammunition in either one. Now let me explain why.

For my full-size piece, I use a fairly traditional store-bought ammuniton (Federal HST's, the +P variety).

For my shorter carry piece, I use HST projectiles that have been reloaded into fresh brass that is loaded with a 'hotter', or faster burning powder in a slightly lower quantity.

Why? Well my buddy who does the loading (I don't know enough to do it myself yet, but give me time) did a whole mess of calculations regarding burn rates, chamber pressures, and the amount of time it takes for a slug to exit the barrel. We then cooked up three batches of ammo (one dead on to his math, and one loaded a little to either side) and went to the range. Predictably, the middle batch had the second highest velocity, while the next batch up (in terms of powder quantity) saw a tiny gain in velocity with a large gain in recoil.

Thus, my ammo is tuned to the gun. If anyone wants the data, I can get you powder types and quantities for that load he cooked up for me.

In the case of this ammo, we are assuming that this is a large powderload of the hottest burning powder availible to a loader in 2070. Thus, regardless of weapon size it will maximize velocity at the cost of safety and controlabillity.

Anything to keep that edge, eh chummer? I'm having flashbacks to my shotgun when I critically glitched with 11 dice... or rather, flashbacks to what was left of the shotgun.

I see. :)

Still, I see little incentive to actually use those over APDS...

...well, if it remains at Availability 12 you can get it at chargen. You can't start with APDS which I believe is 15 or 16. That does make a difference to some.

@Thane36425: As to using this ammo in Revolvers, I shudder to think of loading a Super Warhawk (which is already 6P -2AP with normal rounds) with HA. Even with the "Modified" EXEX this weapon is rather brutal (7P -3AP). Wouldn't want that blowing up in KK4.3's hand, that's for sure.

Believe it or not I asked him to load these for me because the muzzle blast with the standard loads was insane! There was still a lot of powder to burn after the projectile had cleared the barrel, and that was resulting in some heallacious muzzle flip.
I just wish they weren't so expensive to produce, it works out to a little over $1.50 a round with materials (counting the Beer donation for labor).


Are there any more suggestions (in light of my explanations) as to how you would like to see these implemented, or more importantly, what they would have to be like for you (as a GM) to allow them in your game?

My eventual goal for Heavy Angel is to make the site, and the equipment therin, so well balanced and peer-reviewed that the majority of game masters out there would be comfortable telling a player 'anything on this site is in my game'.

Actually what I meant... and I did say it just unclearly... is that at the top end of the spectrum you really do run out of ways to make bullets 'go faster' using gas expansion. With pistol rounds particularly you will run out of cartrige space long before you reach that mark.

While it is damned impressive that you use tuned ammo, in the 'real world' I sincerely doubt your pistol is going to now virtually cut through armor, even if you were to load it with the very maximum you could get. Like I said, the HV rounds are good if you are talking Shirow-esque play, not so good if talking realism.

Do you have the numbers on just how much more muzzle velocity you gained? That would be of interest here.




Not that I'm advocating realism: It's a game after all

Muzzle velocity was right in the 890FPS ballpark, pretty close to the 910FPS as I get out of the fullsize. We loaded these with the intent of trying to match the velocity of my larger piece while eliminating as much recoil as possible.

Believe me that if this stuff existed in real life, I wouldn't let it near any of my weapons as I like them too much.

By the way, Im shooting for the same 'feel' and concept as the HV stuff out of GITS, but I in no way feel bound by their description. I just thought it would be fun to give players nightmares about 'why is that last ganger desperately loading a new magazine into his machine pistol?'

I kind of like these rounds. They are like cyberlimbs and combat drugs - something rare for a PC to use because of the drawbacks and the better options that are available to them, but great to give some extra ooomph to that Barrens ganger. They don't look too seriously unbalancing, either, but that's just from eyeballing them - someone who actually playtests them could give you a better assessment.
