TRIGGER PROBLEM

I have i guess a 3 screw trigger, i looked at the adjustment thread in faq's. the onlt difference is mine doesn't have the sear adjustment, and if i slam the bolt home it drop's the hammer. i have tried adjusting everything but unless i give it a 8 pound trigger pull it just conintue's to misfire. any idea's? it is just new to me so no idea on if it had been worked on before

tHE FIRST THING i WOULD DO IS ADJUST THE REAR SCREW WHICH PUTS TENSION ON THE SAFETY.yOU ADJUST IT IN UNTIL YOU CANT MOVE THE SAFETY,THEN YOU ADJUST IT OUT UNTIL YOU CAN MOVE THE SAFETY WITH A LITTLE RESISTANCE.tHAT WILL STOP YOUR SLAM FIRES AND THE SET SCREW WHERE THE WIRE POKES THREW IS THE POUDAGE SETTING.aDJUST IT OUT TILL YOU ARE COMFORTABLE WHICH THE LIGHTEST i CAN GET 3.8#'S. yOU REALLY NEED A RIFLE BASIX OR A JARD WHICH ARE BOTH QUITE REASONABLE.

thanks Jon i got mine to 3.5#'s couldn't get it to break again, still don't like it i guess a new trigger is in order
