Are you saying post 22 is not correct?
No, I am saying the bullets have to be made to mil-spec. So the quality of the round should not be in question.
I am also saying from a simple understanding of guns and ballistics, you cant have the alloy making contact with the barrel be harder than the barrel, unless you want to replace the barrel faster than the bullets.
There are many “specialty” rounds that do many different things, and if the military has contracted a high penetration round with a steel tip or other feature that does not contact the barrel when fired, then thats what they did. In general that doesn’t make it a ‘steel’ bullet.
