i tested the guns to find the best guns thats easier to win with c my results

the videos are slowed down to 25 percent speed so i could press start on the timer.

here is a video with a millisecond timer showing the damage on a target. for the alternator, r-301, and r-99:

here is another video showing the energy weapons using a millisecond timer: 

here is the heavy ammo guns the spitfire and flatline measured with a millisecond timer showing their damage on a target: 

unless specified otherwise each shot taken at about 12 feet away at the chest, no attachments except for the havoc using the turbocharger for single fire to be accessible.

light ammo:
g7 = 6
alternator = 13
r99 = 18
r301 = 15
p2020 = 12
r45 = 17

heavy:
flatline = 11
hemlock = 10
spitfire = 12
wingman = 5
3030 full charge = 4
3030 low charge = 5

energy:
lstar = 12
havok = 12
devotion = 13
volt = 14

red prowler = 15
red triple take full charge = 3
red triple take low charge = 3
red kraber = 2

bocek full power = 4
bocek low power = 8

mastiff at 2 feet = 3 shots
eva8 at 2 feet = 4 shots
peacekeeper hipfire at 2 feet = 3 shots
peacekeeper ads full charge at 2 feet = 3 shots
mozambique at 5 feet away ads and hipfire = 5 shots

the best light gun is the alternator
the best heavry gun is the flatline
the best energy gun is the lstar

the lstar is faster ttk than the flatline
the flatline is faster ttk than the alternator

so for close hairy situations use a lstar, for further away situations use a alternator or flatline.
