A .50 sniper rifle falls behind by over 25 points of damage to a vanilla .308 combat rifle.
Oh, and by the way, said .50 sniper rifle that falls by over 25 points of damage is also a violent legendary .50 (+25% damage).
The .50 caliber needs such a massive buff it isn't even funny...
This game has no dedicated sniper rifle other than the gauss rifle (which doesn't feel the same).
