> . m855 has a hardened steel core no its still fairly mild steel unless you're talking m855a1 which no civilian has and that stupid cone shape on the green tips core almost always yaws so it doesn't penetrate armor for shit, though it does penetrate cover like car doors and such better then just lead so people tend to conflate that with "armor piercing"  whats even crazier is if you want to penetrate soft thing like trees/wood a tracer will go deeper then a m855 because the longer bullet with prevent yaw  t. had some railroad ties in my yards and tracers were the only thing that went through but i could chop into them and find the steel cone from the m855  both the 7n6 and m855 have bad accuracy due the inconsistency in the placement of the steel cores
