Balancing the L118A and Barrett

So around July or August last year, the Barrett was nerfed. For over a year now it's been worse than the L118A.
Here are just 2 of many threads regarding its nerf. Unfortunately, many were lost with the transition to a new forum.

I did make a thread before, but that was around buffing the Barrett. It's idea 1. Here are several possible ways the Barrett could be made superior to the L118A -

Idea 1: Change the type of weapon the Barrett is.

This was from a thread I made earlier. Thinking about it, it would likely be better than the Disassembler except for the large magazine size.
So instead, it could have a 16 tick delay (20 ticks = 1 second) instead of a 1.25 second delay (25ish ticks). It wouldn't be a slower Dragunov, but instead a good cross between a bolt action and a semi automatic sniper rifle. Would be similar to CoD 4's Barrett I suppose. I'd love to use a weapon like this.

Idea 2: Direct buffs/nerfs to both the Barrett and L118A.
Here are some viable options.
L118A:

• Firerate decrease (1.4 seconds -> 1.6 seconds)
• Damage decrease (18 hp -> 16 hp)
• Ammunition decrease (64 -> 32, or implement a server idea regarding ammunition)

Barrett:

• Firerate increase (1.4 seconds -> 1.1 seconds)
• Damage increase (There are two options here. Make it a one shot kill, barely doing enough damage to one shot; or make it do 9.5 hearts.)
• Ammunition increase (32 -> 64, or implement a server idea regarding ammunition)
• Magazine capacity increase (5 -> 10)

Or of course, just give it the ability to do 10 hearts, but with a crap firerate. 2 seconds? I don't know.

EDIT: IDEA 3 BY @505Herobrine
JUST BRING BACK THE OLD BARRETT AND L118A, THUS MAKING THE ISOLATOR CRAP
LOLOLOL
Okay, the Isolator could be buffed too.
But then the snipers would be blatantly overpowered. Not what I want.

 

I don't think such a minor change is enough.

 

The overpoweredness is strong with this one.

 

The L118A is very hard for beginners to use. I know this because it was extremely difficult.
Making it an average bolt action sniper rifle isn't bad. But just saying, the beginners have a better chance with the M16.
If the L118A was nerfed to 16 hp, or 8 hearts, it would still kill in 2 hits. It would just have less of a chance of killing in 1 hit from any sustained damage that the victim may have received.

 

And show me where I mentioned bullet drop or damage drop off?
First one isn't even possible at the moment, and the second one doesn't apply to snipers in CoD.
Please read the main thread before making assumptions just because I happen to play Battlefield.

 

Oops.
MY BAD

I understand exactly how the Barrett works. Please remember however, that this is Call of Duty, where nothing is realistic. :v
That's already one suggested idea by the way ^_^
