    Mark 7 Presses worth the money?

    Mark 7 presses are not a "Bang for the Buck" proposition, it's a premium product. If your objective is to get primers, powder and bullets into cases in the most cost-effective manner, this is not what you want. Dillon presses get the job done. If that's all you want, can afford, care about or whatever valid reason, you don't need to feel bad about buying one. If you want something "better", then there's Mark 7 with the Porsche 911 of loading presses waiting for you. It's NEVER going to be priced the same as a Dillon, never. That's not how premium products/brands work or why they exist. Mark 7 is pressing the envelope of design and engineering and improving reloading vs. how "it's always been done". I have zero regrets in getting my Mark 7 Evo and upgrading to that from my Dillon 650 vs. going with the 1050, which was my other option.

    Those would be great Steel Challenge loads!

    I'd say you're over-analyzing things. It's only those of us wanting to ensure PF is met for major matches who are harping over a couple tenths of a grain of accuracy. I've been happily loading practice ammo with the MK7 measure as it's currently set up, weighing a charge every so often just to check. If you're seeing a few tenths of a grain spread, don't worry about it at this point and just load away. If you only had a half charge, you still would most likely not have a squib, the only squibs I've ever had have been from cases with a primer and NO powder in them when I was a new self-taught reloader and biffed a couple batches not knowing how to correctly clear problems on my old XL650. Just start loading and shooting, don't let the chatter about this powder measure scare you away from using that sweet expensive press you got! When MK7 get the new parts out for the measures, upgrade then to tighten up the accuracy just for piece of mind.

    Is the rotation speed of the drum programmable on the electronic dispenser?

    They said "after SHOT Show" so at least a couple weeks.

    Well the feedback from MK7 is that the inconsistency is from powder "splashing" back up into chamber during the dump because of the speed of rotation. They're working on a revised linkage that creates a J-shaped rotation with a slower rotation at the bottom, which should help with that. Because of the way the linkage works, you can't really do much as far as how fast or slow you pull the handle, other than making sure you give it a good dwell at the top and bottom to let the powder fully fill and empty, you can't really change the rotation speed of the drum based upon how you're pulling the handle. I've set a top and bottom dwell time of 2 on the auto drive to do this automatically, and it seems to be doing ok, I'm not seeing huge spreads but about 0.2 gr running at 1600rph. So bottom line, if you have a manual Evo don't beat yourself up about it being a problem of how consistently you're pulling the handle, it isn't. The advantage of the auto drive is you can get it to be more consistent by tuning for the amount of splash back you get at a given rph since the speed is exactly the same each time. Hopefully the new parts will eliminate most of the splash back, and then it won't really matter as much. I'd like to see 0.1 gr spread ideally, I'd never give it a 2nd thought at that level. I think most scales are no better than 0.1 gr anyway. P.S. - This also means that testing the powder drop of the MK7 measure by manually actuating the drum rotation is completely useless, you have to test it at the speed that you're loading with a case in the station and shell plate moving at normal speed.

    You should have NO additional flare created by the powder die, if you do it's adjusted too far down with too much pressure on the case. Definitely check what was mentioned about about the adjustment screw being in too far, I had the same issue last summer when messing with it and couldn't figure out why it wouldn't move smoothly. I'm running about as low of a charge as anyone probably is, 3.1gr, and the measure works fine with the adjuster screwed out just far enough to produce that load.

    Do you have the MK7 powder funnel in the powder measure, and NOT the Mr Bullet Feeder flare funnel?

    So if you just manually flip the rod up to the top with your finger, it stays there and gets stuck and doesn't come back down?

    No, definitely NOT ok, the drum needs to rotate fully up.

    Also check the hole in the primer loading slider bar (or whatever it's called, the silver sliding bar that shuttles the primers from the tube over to the shell plate). Run your finger across the primer hole in the bar and see if you can feel any burrs on it, if so use something with very fine grit to gently smooth that out. Primers "catching" on the lip of that hole can cause them to flip. Also make sure there isn't grease or gunk down in the channel that the slider slides in, if it get's slowed down in it's movement due to this it can also cause problems. ADMINS: Would it make sense to split out a separate "Mark 7 Evoluotion Troubleshooting" thread from this discussion, as it's already at 55 pages of mostly blather, and will be difficult for the technical content to provide value to new Evo press owners if these posts are left buried in the middle of all this? Just a suggestion.

    Sorry no video, all I have is a picture which is attached. This bolt in the center that holds the primer rocker arm on, is the one that needs to be tight. It has a shoulder on it that the rocker rotates on, and the idea is that the bolt is screwed in tight against the press and the width of the shoulder is just enough to allow the primer rocker to still rotate when the bolt is tight. On mine, when I would tighten that bolt all the way up, the rocker was being bound up and it would not move freely. Turns out there was a thin shim washer on the bolt that was taking up the slack, causing the binding. After removing the washer, now I can tighten the bolt up all the way and still have free movement of the rocker. I used blue loctite on the bolt as directed by MK7 so hopefully won't work loose, but I'll keep checking it periodically. On the right side under the end of the rocker arm, you can see the black adjustment slider with the locking bolt holding it in place. This is the adjustment for the "resting" height of the primer insertion rod, which is what you can see partially above that with the spring on it. Adjusting this slider changes the height that the rod is resting at in relation to the primer pickup bar that grabs a primer from the feeder tube and then brings is over to be inserted into a case. If it's adjusted too high then the pickup bar can drag on the tip of the rod causing indexing or primer issues. It is supposed to be flush with the top of the bushing that holds it in the primer channel in the press, and no higher. This should be adjusted accordingly and then the bolt tightened and make sure it stays tight. You'll want to check both those bolts periodically just to make sure they're staying tight, as vibrations from operating the press could loosen them over time. That's part of MK7's normal press maintenance procedure to check these periodically. If either bolt is coming loose, it can show up as other issues that you won't immediately know is being caused by this, which in my case was primers getting flipped sidways in the primer feeding bar. In others, it has showed up as indexing issues.

    I'd be in for that also.

    In the support videos it says to use blue loctite and make sure the bolt is tight and does not back out. When I tightened mine all the way tight, the rocker would bind up and not move smoothly. There was a thin shim washer on the shoulder bolt, when I took the shim off then I was able to tighten the bolt up fully while still having free movement of the rocker. Per MK7 Support that is fine, just always make sure that the bolt is greased up so the rocker moves smoothly.

    Is your primer rocker arm moving freely with the shoulder bolt that holds it tight? I had an issue similar to what you're describing and it was the primer seating shaft sticking up slightly into the path of the slider and causing it to snag occasionally and mucking things up. The rocker arm was not moving freely and was causing that shaft to stick up just slightly sometimes.
