Anyone have any experience doing 223 case prep with there Mark 7?

Mostly wondering what clutch level your using. I was using 2-3 during setup of the dies but I was applying imperial sizing wax to each case. After everything was dialing in I lubed a couple hundred cased with what I thought was a generous amount of Dillon case lube but I'm having to run the clutch at 15-20 do keep it from "stalling out"

Just wondering if this is normal or if I should be using more lube. The cases don't seem to to be sticking so I'm thinking it's fine but curious what others might be doing.

Thanks!

Some great information on .223 processing and loading - http://www.doodieproject.com/index.php?/topic/4259-mark-7-hotness/page-5

I run 223 brass processing at Clutch = 0 or maybe 1. On startup sometimes I have to hit the run button a bunch until things get warmed / lubed up. I don't think I've ever run it at more than clutch = 3-4.

Troubleshooting - I assume either under-lubed or one or more stations need to be adjusted. Time to get methodical.

Will the machine run empty at Clutch = 0?

Put in a single case. What station(s) does it stop at?

Hand-lube that case. Try again.

Have you ever taken the machine down and cleaned/lubed all the moving parts? It's not so intimidating if taken on piecemeal.

Sweet great thread, I'll read it all the way through when I have a few minutes, thanks again

Just tore the machine completely, cleaned and lubed everything before starting the 223 prep. I played with more/different lubes and can run it at 5 now. Much better.

SO guys I have had my Mark 7 since Nov, and it has been awesome. I have been loading tons of 38 comp and I can tell you it's a pain in the ass at 1500 phr unless you tighten the damn shell plate down hard! I still get a touch of spilled powder, well not anymore. I have also been loading 223 and came across this small company called fast and friendly brass. This guy is in the brass prep'ing business but also make some cool items like very close tolerance shell plates #3 and #5 for Dillon 1050. I liked it because the 223 brass didn't move around a lot loading at 1200 phr. Well I had to load some more Comp and I thought I would give the new plate a try. Holy crap 1800 PHR not a darn thing was spilling and the plate was tighten down like the book says and not cranked down. Here is crappy video I made..https://www.youtube.com/watch?v=RfcC_X4xAyE

I'm curious and have a few questions :)

1. When changing calibers how does one go about determining the tightness of the shell plate? I always cycle the press slowly and if I feel too much resistance I loosen the nut. What is the procedure for this with the Mark 7 installed?

2. Do the new ones ship with the EMI filter for the casefeeder or does that have to be ordered separately?

3. Do you guys use the DAA powder funnel? I don't because I do not like the "thump" feeling when the case slips off the funnel. I hardly do not have a bullet that does not tumble during indexing, so I figure I will have to use the DAA funnel. I do not see it mentioned in connection with the Mark 7, so I am curious to know if people are using it or doing something else to keep bullets from toppling over.

1) turn off sytem, pull it down manually to where shellplate can be spun by your fingers, thats how you do it, shouldnt really use handle

2) pretty sure they all do?

3) On a super 1050 you dont use the DAA powder funnel, station 3 (expander) takes care of business and belling/expanding it.

I got my Mark 7 last year, and received/installed a filter AFTER I experienced an intermittent EMI/tablet reset problem. Not everyone has an isse, as I understand it. My problem is resolved.

I'm definitely using the MBF powder funnel. My swage backup rod (Ano, what I think you mean by Station 3) is set for swaging, I don't give a thought to anything else.

It doesn't expand enough to prevent tipped bullets for me. I use the MBF Powder through expander, and just deal with the clunking. Now that it's not my arm feeling it, it's not a big deal.

The clunking that i think you are referring to is a function of no case lube in the case mouth. I lube in a half cardboard box with 1.5" sides - holds about 1,000 cases at a time. couple of sprays across all the cases, jiggle em around do another spray across all the cases. Then I jiggle the box to stand up the cases and get about 80% of them stood up. spray the lube across them. you can repeat the last step if you want but the idea is that the loading operation is butter - nothing sticks or clunks coming off the powder die as this can lead to other issues. The entire lube operation takes 20 seconds/1,000 rounds.

I no longer use the MBF die per Rick(MBF). I use a Lyman M die in station 2 and a regular dillon powder die. Got rid of all the clunking/sticking. I also do not use any case lube.

That's interesting. I'm not loading alll pre-processed brass (size/decap, swaged, u-die resized) and just pulled the decapping stem from Station 2 as it wasn't doing anything other than breaking pins if I got an upside down or toppled case.

An M-die seems like a better plan.

Station 3 - (1) hold case in place, (2) expand if you have the right swage backup rod installed. I don't use it for (2).

I just went to the press and checked a sized case and a cut-away 9mm case I use to adjust the swage backup rod. The swage backup rod is set deep enough to support the case against the upward pressure from the swage rod and I can't see setting it any deeper.

Yes, the swage backup rod is roughly 9mm diameter at the top, and it easily slides into the case mouth. I see the expanded area, maybe 0.356" (hard to measure without removing the backup rod).

No, it didn't expand the case mouth enough for me to manually insert a 9mm 135 grain polymer coated Bayou Bullet (0.356"). Maybe it would work with 0.355" or jacketed bullets.

So I still think you need a M-die, Dillon or MBF powder funnel to properly expand the case mouth.

Am I missing something?
