Well here's what I don't like:
F4U-1C = represents 1776 Hispano rounds on a 2:2:1 AP:HE:Tracer (assuming it's different then AP for the sake of argument) or 1848 of a 2:2 AP:HE mix
Fw-190A8 w/ 4 20mm = 1383 Mauser AP + HE rounds on a 1:1 basis + mine (includes 1:3 ratio mine shells) (no tracer ratio)
Fw-190A8 w/30mm = 888 Mauser AP + HE rounds (1:3 mine shells as well) plus only 110 30mm Mk 108 rounds (HE-mineshell only) (no tracer ratio)
P-51 ( 6 gun config) 3609 rds of 2:2:1 AP or AP/I, Ball, Tracer ammo.
That's taking into accout properties of common rounds for the gun worked into each shell as if they were different to distingish the two (most are) . If all bullet strikes hit the same object that's the amount of historical rounds that virtually hit the target.
Actual results, such as on armor:
F4U-1C = 462 AP rounds
Fw-190 w/ 4 20mm = 260 AP rounds
Fw-190 w/ 30mm = 167 AP rounds
P-51D = 752 AP or AP/I rounds (940 including tracers)
It's a monsterously unbalancing set up, if anything else is considered going to be considered historic. Every round is a double hit or triple hit in precisely the same place. The damage model can't be anywhere near historic realise (which is leathal enough as it is) because ALL rounds have X2 or X3 their hitting power, plus the side effect of simultaneous hits.
I've not really for player selected ammunition. That's to much of a hassle for programming an interface and all that bull...
However I hope eventually that the FE can be programed (or already is capable of) to distingish strikes of different ammunition from the same gun in fast firing guns, along with ballisitc characteristics that differ from round to round. The capabilities in the physics engine are their, evident in the Panzer. It can also tell the difference between a 20mm and a 30mm, or a 13mm, or even different rounds from different guns of the same caliber.
Until the round type snafu is handled there's really no point in debating damage modeling from a historical POV, because whatever a plane's toughness, it's going to have to be at least 2X to compensate for the guns. And along those lines, alot of the guns lose out. Most have good HE preformence but poor AP preformence and really lose out to the Hispano because of it. This also screws up the bomb's destructive power as well. Everything has to be toughend up the compensate
Unfortunately you either get all capabilits or only one capability, in which case your going to mess something up either way
