First time out of the vault

I do not know if i see this right so plz claryfy it for me. I encountered this damage modyfier:
http://fallout.wikia.com/wiki/10mm_(Fallout)
and i compared it outcome with this gun:
http://fallout.wikia.com/wiki/10mm_pistol_(Fallout)
and the purpose of this two ammo types stared to be unclear to me.
Let say i pushed 10dmg from this pistol and i am attacking two enemies from who one have no armor and one have armor on.
So:
1.
Flesh creature with no armor against 10mm AP. 10dmg reduced by half and -25% DR is not aplied due to lack of armor.
Outcome = 5dmg
Against JHP damage is doubled and 25% reduction is on so (10x2)-25%=15
Outcome = 15dmg
2.
Armored opponent with armor value of 25% against penetration round gives me 10/2=5
Outcome = still 5dmg.
Against JHP you have 10x2 -25% from armor and -25% from mod gives you 10dmg.
Outcome = 10dmg
It turns that anti flesh ammo is better versus armored enemies than anti armor bulets. There must be a mistake in my way of thinking but i am unable to see it. Plz correct me.
