Nick_shoots_fast Posted April 7, 2020 Share Posted April 7, 2020 Hey guys. Looking to get a 223 conversion for my mr bullet feeder. Loading by hand takes way to long but wanted some feedback first on how it works. well, how does it work? I didn’t know if people were having problems with the bullet seating and not toppling over when it gets rotated To the next station. Link to comment Share on other sites More sharing options...
zzt Posted April 7, 2020 Share Posted April 7, 2020 (edited) I no longer load .223, but I can tell you that in every caliber I do load, the MBF funnel/expander does an excellent job. Bullets always drop in vertically and stay that way when moved to the next station. I have found that with lighter bullets, the last 1 or 2 in the tube do not drop in with as much force as usual. Not a problem. Edited April 7, 2020 by zzt Link to comment Share on other sites More sharing options...
cvincent Posted April 7, 2020 Share Posted April 7, 2020 Most guys use an M die for neck expansion, then bullet toppling is not an issue usually. The dropper needs some work to feed 55 grainers reliably. I had to chamfer the ID of the dropper, there’s a ledge that the Bullets get stuck on. The spring in the micro switch needs adjusted, bullets also get stuck from the spring tension. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

OnVacation Posted April 11, 2020 Share Posted April 11, 2020 I run the MBF mini and I don't expand, and haven't had any issues with 62gr FMJBT or 70gr Nosler RDF. I imagine that expanding might help if you're running a flat base bullet, or you have particularly rough case necks or light bullets. with chamfered cases and BT bullets I've had zero issues. I don't run a lot of chamfer, just enough to deburr the inner neck. YMMV. I have not tried running 55gr through mine yet, I prefer the 62gr and 68gr for most of my uses.

I mean, it was more work than setting up 9mm, but less work than 300AAC. Search in the reloading forums. Many topics on it.
