There's getting to be some good models of tanks and artillery out there, but often there are no suitable shells or ammunition for them. There are some good freebies on Turbo Squid, once you get through the conversion and scaling, but they onlt suit a few guns. For example, a 120mm APFSDS round for the German-designed gun in the M1 Abrams. Now, it doesn't look terribly hard with the right modelling program, if you can get a set of dimensions and a good reference picture. I think the trick is called something like lathing a spline. And, when you have models like the FLAK 36 and the PAK 40 on Vanishing Point, it'd be good to have the crew handling ammunition, and the clutter of discarded shell casings. Amyone want to have a go?

Is this the ammo you mean ?

I know there was a set of shells and crates available from Kurokuma that contained a wide range of shells. I have the set, but I don't know where it is to be found now.

Post up some reference pics and I'll make some ammo and put 'em up as freebies.

There might be enough info on this site: Scroll down past the booklist, and you'll find links to a photo gallery and data list. Another resource Maybe not so good on ammunition, but it looks like a huge collection of historical photography. One minor curiousity is that some of the models on Turbo Squid are labelled "grenade"--I think it's how somebody might have mistranslated German. Suggested Shortlist. German 88mm FLAK 36 (Also the gun on the Tiger 1 tank) German 75mm PAK 40 British 6-pounder (57mm) (also in US service) American 75mm (Sherman tank and some British) The more powerful German ammunition for the Tiger II and the Panther would also be worthwhile. (Yes, I'm thinking of the Vanishing Point range, and their free artiller models.) I know that there's quite a bit of small-arms ammo about. Quite a few rounds are known by different names to different users, and sometimes there are significant differences, such as between the civilian .308 and the military 7.62mm NATO. I'm not going to worry about the odd millimetre, but some designations are misleading. You know that .38 and .357 pistol rounds are te same diameter?

I'll take a shot (pun intended) at them tomorrow.

you mean there's not a .023 difference?...;)

As for varying the caliber, that's what the dials are for...;) If I could do shiny metallic textures in Poser, this'd be pretty simple stuff. (except in non-Draft mode...still haven't figured out how not to get inflatable models that way...;)

I'm pretty sure that there's a Firefly model out there, too:  a Sherman re-equipped with the British 17pdr AT gun and used by Canadian and Polish armoured forces, as well as British, in Normandy and subsequent campaigns.

The calibre of the 17pdr was pretty much the same as that of the US 3-inch AT-gun, but the 17pdr was by a clear margin the more effective weapon.   Both the 17pdr gun and the Sherman Firefly modification were offered to the US army, as the 6pdr had been (as AntoniaTiger mentioned earlier), but, unlike the 6pdr, the 17pdr was unaccountably rejected and so was the Firefly.

never overestimate the military mind...;)

Ain't had time to start these yet but I added the links to my bookmarks and I'll get to them later in the week.
