The Best That Never Was 2 (Prototypes)

I lost the original worksheet, but I think I used TL 3, based on the burst radius I got for the shell and hypothetical shrapnel. TL 2 would only have B:3 for shell instead of the B:4 that I have, and TL 4 shrapnel would be B:10 where I have B:8. Honestly, I'm wondering now if I did it as artillery and then backed into the Pen using muzzle energy and just screwed up the range calculation. Plugging in a 3.2 cm, 28 caliber gun for TL 3, I get 154m short range, which is much closer to your 157 than my 90, and all the damages match my write-up.

That may be; I did it as a rifle. Plus, of course, I have some fudges, like all good GMs do

what about a homemade Hotchkiss 37mm gatling black powered cannon vs. APCs or a something like old moses vs m113. I could see them using darts or shells and not iron balls.

There is a lot of kinetic energy in a fast moving heavy and solid iron ball. Modern armor isn't really made to deal with that kind of projectiles. And a "well placed" shot on the drive wheels would surely immobilize the vehicle.

Against soft armored targets, the iron ball would definitely do real damage.

I just have to ask because the meaning of a word or phrase might be readily apparent in one country and completely meaningless in another, so, what is "old moses"?

[Legbreaker]

It's a civil war era cannon. Not sure if it's a 6 or 40 pounder. It's been on a few episodes of mythbusters.

Cheers,
I don't watch Mythbusters often enough to know all the things they do or gear they've used so "Old Moses" was completely unknown to me!

Yeah. I tended to skip it myself when it was still on, but I did catch one episode where they'd mentioned it - enough to recognise the name given to the gun.
If I hadn't seen it, I'd have been as in the dark as you.

I went with artillery because FF&S says the small arms calculations are only intended for calibers of 20mm or smaller, but I probably back-figured the Pen like a small arm because it was intended for anti-personnel use.
