One other bit of silliness I’ve noticed, specifically involving ammunition crafting.
Big one is, as with a lot of games where you can handload, the bullet material is simply a quantity. No need to find or make bullets for different cartridges, no bullet molds, etc. While it’s probably more complexity than it’s worth, it does stand out when compared to requiring the right type of primer and the right case.
Also, bullet materials. Silver or other oddball metals would probably work good enough for buckshot, but rifle bullets…well, Mythbusters had a Fun time trying to actually hit a block of clay using a .30-06 with silver bullets, due to shrinkage.
Also, rimfire rounds. In general it isn’t practical or safe to reload a deformed rimfire case, but I recall an article in Backwoodsman magazine discussing the idea, with an eye towards .44 Henry and other old, uncommon rimfire cartridges. Apparently if you can get the priming chemical into the rim, a case can be reused once, maybe twice if you take care not to bring the hammer/firing pin down on or near where it was fired last time.
The article also recommended the use of WP from strike-anywhere matches as a source of primer for old rimfire cartridges, though good luck finding those these days. I can’t actually recall if the game presently has any rimfire guns that aren’t .22, but if we had a blackpowder Henry rifle, it would be an interesting option. o3o
Last but not least…seriously, treating .270 Winchester as a variant of .30-06? >w>
