Problem with animating hands

[FZFalzar]

Hi all, I've encountered this weird problem when I'm animating. When I animate my gun tilting down using auto-key in 3DSMax, everything is fine. However after that, lets say I want to animate the hands removing the mag, whenever I try to rotate it then the arms fly all over the place as if the guy broke his bones or something lol. I'm not sure whether it is the correct object I'm supposed to rotate (im trying to choose the lefthandIKtarget thing and i also tried the leftpalm). Any guidance would be appreciated
