alright so recently my brother brought me a master padlock from the local school. So I went to picking and to my knowledge there are 3 pins. No security pins just your average everyday pins. So (keep in mind im decently new to picking) I set the pins and the lock turn clockwise to about the 3 O' Clock position, but the shackle won't come loose. I thought I'd try the putting tension the other way and sure enough it turns to about the 9 O' Clock position and the shackle still won't come loose.
I tried using a homemade shim on it and cursing at it. nuthin. Any Ideas? here is the lock.
the engraving on the back says "Master Lock: V53 17752346" and then inverted below that is "02"
