I tried sniping for a bit and it was just aggravating. Most of my first shots didn't get hit markers but I saw a bit of blood splatter on the enemy meaning that I hit him. Then, it would take 2 more shots to kill because the first shot didn't count. Sniping with the TAR is better than sniping with a sniper rifle in my opinion.
It feels like the only way you can kill someone with a sniper rifle is with Exacto ammo x_x
I love my shotty even with its limited amount of ammo.
It would be used way to much IMO if it had more ammo, I feel that Ubisoft got the balance right on this weapon.
When I run out of ammo I just look for a swap from one of the dead guys I just wasted.
Ammo box's are my best friend.
I have never even shot the sniper rifles however IMO a 50 Cal. should be a one shot (above the waist) one kill always.
