MEC builds great machines and all...but the automatic primer feed has got to be one of the worst designs I've seen. On my MEC 650, I've sat and fiddled with that darn thing and I can't get it to consistently drop primers right, sometimes they'll hit right on the hole and other times it will completely miss it and fall off the machine. After messing with it for an hour and a half, I figured it was time I come up and ask for some wisdom from some of you, to see if I can solve this problem. So, my question is, HOW DO I GET IT TO DROP PRIMERS RIGHT?!?!

I'm using CCI primers if that means anything. Thanks.

Well 687EELL, I tried your idea and I'm positive it would work if I could just figure out a way to keep it in the same place and not move around and come loose again. If I can't figure this stupid thing out, I'm just going to spend the $70 on the new bigger primer tray and be done with it. I can load faster just by taking the automatic primer feed off and put them on by hand, at least I don't have to stop and rearrange the primer that way...

Then you might want to try their new primer delivery system. It has been out for over a year now and I think it cost about $65.00. But, if you get the old one set right, it will do just fine. John

Loosen the bolt and push it all the way into the slot. Then tighten the bolt while keeping some pressure on it so it stays all the way in the slot. Now comes the tricky part, you have to bend the bracket so the bottom of the tube lines up with the hole in the plate when the down stroke is complete. I use an open end wrench to bend it, you also need the bottom of the tube to clear the plate by about a 1/16 inch. Last but not least you have to adjust the timing by moving the balls on the little chain so the primer is released at the bottom of the stroke. HMB

Get the new primer tray. You can fiddle with the old one forever OR you can quit watching the primer drop with the new one. Follow the directions when you adjust the new one-very important (or you can be like me and finally read the directions after you are frustrated). Pay attention to the 2 dots alignment, you'll know what I mean when you get it.

Jolly, before I got the new primer feed I had similar problems.

One thing I did to help the primers to fall better, was to take a dremel tool and chamfer the hole where the primer starts to fall.

I cleaned it up pretty good, as I really didn't have many problems with it after I put a nice chamfer in the hole.

You might try this.

But........if you can find the new model primer drop, they work a lot better.

I just checked Graf and Son's website and the new MEC primer feed is $51.99. I don't know anything about a sale flier. Connie's Components has it for $44.99.

I have installed them on all my machines and they do work great. Sometimes you need to tweak them a little so don't get frustrated. Once you dial them in, they don't miss a drop.

Check the pull chain adjustment, if its too tight it will move the tray. Line up the tray drop tube first, on the down stroke, tighten the set screw, then adjust the pull chain so the primer tray arm moves the primer to the drop tube.
Have patience and it will work, Have a nice day.

a small piece of sandpaper between the clamping bracket cured my problem. set the drop tube very close to the turntable and tighten down with a screwdriver. be careful positioning the drop tube and set the bead chain so it doesn't pull on the primer tray assembly.

Hauxfan, yer right, they do work better than the old ball n chain type. My home made still works flawless! Still waiting for miscue, none yet! :) Hap

I used a rat tail file to make the transition from the metal tray to the tube a clearer path. The tray overlapped part of the tube so the drop path wasn't right. Then I got the rest of it right with the chain etc. Now I rarely have problems.
