Well i guess my accuracy with karabiner will be really poor because i practice shootin at objects all the time just randomly when walking...and to begin i thought the aim was slightly off compared to where the bullet went...i was paranoid that it shot slightly left to where i was aiming even when stood still

Accuracy cnt really be used to make a full judgement on a player i dont believe anyway!! I would rather look at kills-death, cos some people have strangely low deaths

or even more make a judgement from playing against the person :P
