Why bullets from aluminum are so rare? They can go fast and are relatively hard, so they have some pros.

>>65461989Because steel/tungsten core>the rest.Soso, this >>65462037.YNTGBNTGB
>>65461989Because light bullets are a novelty. Oh you want a 50 grain 9mm that can go 1900 fps?
>>65462067Which pierces most IIIA
>>65462116I have some steel ball .45 that should.
>ESL slide thread #5318008Why haven't you removed your sad brown existence from my planet, turdskin?
>>65462346nope. too slow and too large.
>>65462116So can a hardener steel penetrator
>>65463172The Liberty 50gr 9x19 is readily available for sale and doesn't risk getting the ATF on your ass. Proper 9mm AP will have more authority however. Tungsten core DM91 will perforate some Level III PE plates even out of a long barrel (see Buffman).
>>65462037what the fuck even is this? your contention is OP doesnt use reddit enough?
>>65461989>relatively hardrelative to what?
>>65461989Lead is cheaper. Steel is even cheaper than lead.
>>65461989because that's fucking stupid. a better question is why the hell aluminum cases arent the standard for carry ammo? that shit is light af compared to steel or brass
>>65463342Might be because thermal conductivity. Aluminum transfers heat pretty well compared to brass and steel
>>65463348I could see that being a concern in a machine gun, but not when you're mag dumping into a chicken washer trying to mug you
>>6546316Tell those 3 dead feds I have in my dead nigger storage
>>65463342Ductility and reactivity of aluminum are poor compared to brass.
>>65463342Aluminum has burn through problems, if it's oxide protection layer is destroyed it starts very active reaction with gunpowder burn products that reaction melts through cases.It's possible to mitigate with plastic protection layers (us mil uses 30mm aluminum case rounds) but tech is not as simple as "just make aluminum cases".
