Emik S30 + Bull Tac10
I forgot to write down the decay BEFORE my 10 ped ammo test, so I will go have another try. They use 1 blp light cell, and do around 6 damage, so it suggests it should cost 1 pec more in decay.
According to pe-wiki.info it's economy does indeed goes as far as 3.94 including markup, making it a cool low-life killing pea-shooter.
Even though it shoots one ammo, sounds just like a Maddox I, making a multi-shot sound
. Of course you do twice the damage on the Maddox, but with the same amp, your skills would need to be pretty high.
It's the best weapon to kill fugas and little birdies, maybe even snables. Birdies will run off after the second shot, but the above combo shoots rapidly blasting them before they do. The little damage ensures that you don't waste too much.
DO NOT SHOOT BIRDS WITH THIS OR ANY OTHER WEAPON, I GET BLANK NO-LOOTS FROM GIBNIBS AND OTHERS.
Skill gains from 10 PED ammo:
BLP: 154 >> 222 = 68
Handgun: 989 >> 1004 = 15
Aim: 600 >> 602 =2
IRD: 840 >> 845 = 5
Those are worth about 3-4 peds by old-school ESIs.
