Thread: Please help to identify these two MEC 600 jnr Charger bars

The top one is to allow varying powder charge weights by screwing in/out the long screw. The short screw hole is top provide a stop when sliding the charge bar back and forth from powder charge to shot charge. You will have to throw charges to determine the actual drops of powder and shot charges.
The silver bar has the lh hole recessed to accept a range of available Mec powder charge bushes. The rh hole is for shot charge and you will have to drop a charge through it and weigh to determine the actual shot charge wgt.
