I'm making a game (does not matter, I will not post it as its not ready and its kinda personal)I chose 10 calibers for the game and I want you to rate themeach caliber is represented by a single loading (e.g. no fmj/jhp difference for 9mm, as I consider the difference between calibers to matter more than individual loadings in cartridges)there are 5 armor piercing calibers:10mm Auto - armor piercing loadbasically fucking +P++++++++, maximum load 10mm with a bullet that has a steel penetrator plus coated with teflonI consider it viable IRL because there's Russian 9mm AP ammo that easily pierces soft armor, it should technically be better than 5.7 because its a higher caliber henceforth bigger wound channel after piercing the armorregular AP 5.7x28mmregular steel core 5.56x45mm6.5mm CBJ (solid tungsten penetrator)7.62x51mm (tungsten core fmj bullet)now, I forced different LLMs to estimate penetration of those in mm RHA and I got the following table10mm Auto (steel core, Teflon) 4.6 mm RHA5.7x28 AP (tungsten alloy small core) 8.1 mm RHA5.56x45 (steel core / M855 style) 17.0 mm RHA6.5mm CBJ (tungsten kinetic penetrator) 19.8 mm RHA7.62x51 (WC-core AP) 20.0 mm RHA / 15.3 mm RHA (steel core)so considering this I divided those into 3 categories10mm, 5.7 and 5.56 penetrate soft body armor (named PDI level I ingame, which is rated for everything that is not AP)6.5 and 7.62 penetrate PDI level II which is rated to stop 5.56there is also PDI level III which is designed to stop AP 7.62 but its just fringe so its unlikely i'll implement itnon-armor piercing calibers:lead round nose .22 (5.6mm)lead round nose .380 (.380 is based because it kicked off WW1)COPPER plated, (not an FMJ) 9x19mmpolymer coated JHP .45 (called 11.43 Hydra ingame because I hate the imperial system and the game is set in europe)9mm copper plated hard cast lead buckshot (12 gauge likely fits around 8 bullets of spherical 9mm buckshot) 12 gauge
I dont really get the question. Seems like the system of categories is super granular in a way that doesn't matter. Just have your 5 round types with generic AP and non AP loads and leave it at that, you don't have to rationalize why the 10mm AP is more effective than 5.7 AP.
