My 1ks has triple tap and with one sniper ammo increase gear I start with twenty three when I run out of ammo provided I hit all head shots I have put in 37 shots when the ammo nerf for snipers 5 to 7 bullets and the 100 yard stare probably like a 3 to 4 bullet nerf hit at the minimum I lose 8 starting bullets so I would start at 15 with a sniper piece on at the best so with the triple tap all head shots I only end up doing a possible 22 shots of damage
