Just bought the Dillon XL 750 w/Mark 7 Autodrive

I got no advice for you, just envy.

That's a couple I couldn't live without.

Just realized you switched to a Dillon,

A solid bench is a must with AP presses. Caliber conversion setup. Multiple tool head. The brass trimmer is real nice.

Plenty of supplies

I'd also highly recommend the DAA add-on kit for the Mr Bulletfeeder...addressed several bullet feeding issues

I find that part kinda humorous, because it's a kit to fix problems with the Mr bulletfeeder, but not made by them. But it is sold by them on their site. So they would rather sell this add on kit ($90) than redesign their bullet feeder so it didn't have the problems to begin with.

The best upgrade I could suggest is a 1050. The swage station is really worth it when it comes to priming, even more so with automation. If you could ensure all of your brass has pockets ready to accept primers then a 650 with the most reliable primer feed out of all progressives would be a good upgrade.

As far as bullet feeders go, see if you can find one of the GSI feeders, they are the best I have for Dillon machines but I do have Hornady, KISS (before the two guys split up and the name changed to MBF) and the current MBF, they all can work.

With all presses, I highly suggest you set it up and use it as the manufacture intended it to be used first. If you decide to not do that, you will have no idea if the changes you make, make the press better or worse.

This will be even more important on you 750 with an auto drive, you should have, at a bare minimum, hundreds of issue free loaded rounds with it before automating it. If you don't you are going to get frustrated and any call you make to Dillon will not gain you much sympathy.

I recently bought a 750 and from my understanding, Mr. BF doesn't work with the 750. Due to interference from the powder measure? Is there another option or way to make a bullet feeder work on the 750? I called DAA and was told no fix/option is available... I am new at the entire reloading hobby so I don't have the best understanding of all the options available, specifically the bullet feeder for the Dillon. I would like a bullet feeder so I can watch all the stations at once.

As I said above, if you can find a GSI feeder, it won’t interfere with the powder measure and you can feed and seat in #4, so you can retain the powder check in #3. The column of bullets is outside the area of the original tool head.



The fail safe rod is what determines where the powder measure is clocked. So you would need to figure out how to relocate it, in order to rotate the measure out of the way.



Or revert back to the first generation of Dillon powder measure linkage (Black one) that had no fail safe rod and used springs for return.



To do that and not have a powder check wouldn’t be the best idea I have heard this week and to automate one without powder check would be asking for trouble.


Will the dropper not work in #3 or #4 on the 750 from the factory?

You spoke to DAA recently? The reason I ask is they sell a short powder bar for the Dillon Powder drop designed to be small enough that you can put the Mr BF in station 4. I don't know why they would tell you there was no fix available. This has been available for at least a couple of months.

Also, I just mount the BF in station 3. I really don't like powder checks. For me they keep pulling powder out and I prefer to eyeball every round anyway. With the 750 I've never had a double drop (it's impossible to do unless you take a case with powder out and move it back a station). I have had 2 cases fail to get powder (it happened because I accidentally left 2 different bullets in my bullet feeder and when they popped out to get rid of them I short stroked and missed feeding the powder). In any case eyeballing caught it. I prefer to seat and crimp in 2 different steps anyway.

what I thought...

That's what I thought... Maybe they didn't understand me but I clearly asked if they were close to coming up with a fix for the 750 so the MR. B could be used. I was given the ole COVID excuss. I left it at that and end the phone call.

Good to know. I haven't started reloading yet and bought a powder check because I am new, figuring every safety check I could have I would get. Either way, the short powder bar fixes the issue? And we can still seat and crimp separately.

One more question or for clarification purposes, can I use the Mr. MINI Bullet feeder or does the short powder bar only work for the regular (with collator) Mr. Bullet Feeder? The reason I ask, DAA still has this warning in red on the product page for the mini;
"The current design of the new XL750 does not allow the bullet dropper to be positioned in station #4 of the toolhead because of the angle at which the powder Dispenser bar extends directly towards it. This means the bullet dropper MUST be positioned immediately after the powder dropper, in station #3. That makes it impossible to use a Powder-Check AND a bullet dropper at the same time."

"We will attempt to come up with a solution to allow the powder dropper to be rotated to another angle to resolve this issue, but at the moment, be aware of this issue."

I agree, the mini mr bulletfeeder is a lot bigger around the area near the dies. I don't think it will work with the short powder bar.
