I use to buy Straight .36 Grey BB's for my sniper rifle because they are very accurate. (Unfortunately they don't make them anymore)
The colour also makes a huge difference when sniping because you can get a couple of shots off without anyone knowing your position.
Even out in the open when you shoot at someone and they spot you, they generally don't see the BB's coming unless they are very lucky.
I was considered a real threat to the other team.
You had to be very careful in gaging the distance of the victim, Because you can injure them if you shoot them when they are too close. We have a minimum shooting distance of 20 metres then you have to use a secondary weapon - pistol.
