How to adjust powder and shot?

I just bought a used MEC 650 from a friend. I’ve reloaded rifle and pistol for decades but not shotgun. How do I adjust the powder and shot that is dispensed? On my Dillon there is a screw that adjusts the volume of the bar space but I see nothing like that on the MEC.

powder and shot are adjusted with bushings that are in the bar, A different bushing is used let say from 1 oz. to 1 1/8 oz. of shot you would use a bigger bushing.
You look up on the bushing chart what # of bushing for a particular powder and charge weight of powder, shot bushings are marked as per how much shot the bushing will throw.

The bar is generally fixed for one weight of shot_ex: 1oz, 1-1/8, 1-1/4, 7/8 or whatever. The powder for the bar is changed using bushings. That said, the bushing chart is NEVER right when it comes to what it says the charge weight will be and what it actually drops, so a scale is crucial. My current load called for a #26 bushing but the weight I wanted wasn't achieved until I went to a #30.

What load are you trying to achieve?

This, all the way. There have never been MEC shot bushings.

True, but I do have a 170s era Mec bar for a 600 Jr. that was drilled out for Texan shot bushings. I got a bunch of the shot bushings at a flea market for $1.00 each. Works great.

Yes your right, but other shot shell loaders have shot bushings {Texan, Ponsness-Warren and older press like Bair, Pacific, the Hornady 366 no longer made and others}
Sorry after I tried to explain how it was done I remembered MEC uses a fixed bar.
I hope the poster asking about adjust the powder and shot is not confused by my answer..

Yes all very true, there are machines that only use bushings and some MEC's that can use a bushing but its not a MEC bushing. Why MEC has not marketed a system that uses bushings on both sides is beyond me.

The modern RCBS Grand uses bushings for both (and PW ones work just fine)

So they can dell more charge bars.....seriously, they should have done that a long time ago because the charge bars will drop differing weights depending on the amount of antimony in the shot

All you need is a MEC 1 1/4 oz. bar with a dog bone and a lathe. Using your lathe remove the flange from the MEC bushing and then reduce the bushing OD to fit snuggly in the 1 1/4 oz. hole. Slick.
