Mr. Bullet Feeder - bullets tilted or fallen off case

Recommended Posts

I have been using MBF for 3 years with no issues.  Starting recently, every 10 rounds or so the bullets would be tilted after it rotates to station #4.  The bullets drop into the case upright, but once the shell plate starts rotating I can see the bullets start to tilt. 

 

At first, I thought the case opening might be too wide. So I adjusted the expander die (the one comes with the MBF) - have been using the MBF expander die (e.g. powder funnel) since the beginning, to have a smaller opening.  However, the result is even worst.  Almost every other bullet now just falls out of the case when the shell plate rotates.

 

I watched DAA setup videos a couple times, but they did not talk about how to "insert the bullets harder into the case opening".  I tried lowering the bullet dropper tube (the piece that is secured to the top like a die), thinking maybe over time the whole MBF has been pushed up gradually by repetitive force, but that did not help.  

 

Any ideas?

WAY too much bell. Try dialing it back a tiny bit at a time.

 

I have a 550, but use the MBF powder die instead of the Dillon one. The MBF is amazing at making the perfect bell even in 9MM range brass with everything I have thrown at it. Even with what others refer to as garbage brass. Between that and a Lee Factory Crimp Die I have zero feed issues.

Did you use the MBF powder funnel? (see picture below)

 

Is that a new bullet you're loading? Have you always used a bullet with a lube groove? 

 

Dillon on the left, MBF on the right.

Yes, have been using the MBF expander die (e.g. powder funnel) since the beginning. 

 

I have always loaded this 147gr 9mm coated bullets with groove since the beginning.  Appox 80k loaded so far.

Do you load jacketed or coated?  Lee FCD does crazy things to coated bullets and I have ditched it for a regular taper crimp die long ago.  Also, I did try very small bells - they shave off coating off the coated bullets when too small, plus, the bullets just fall immediately the moment shell plate starts rotating when I adjusted the bell to be very small.  I just feel the bullets are not being "inserted" into the opening, but rather just gently placed on the mouth.  I am hoping there is an adjustment I can make the MBF push down harder when the shell plate is raised up.

Well that's all I got, lol. I'll allow members with more MBF experience to take it from here.

 

Good luck.

A combo of  1.  too much bell, and 

                       2.  the crazy shape of the bottom of the bullet (only about 1/8" below the groove).

 

The bullet tips easily into the groove  - if the bullet were straight edged, I bet you wouldn't have any problem.     :)

Put a spring or rubber band on the feeder die to give more downward pressure.  It should help seat the bullets a bit.   Armanov sells a spring kit.

More seating pressure might bandaid the issue, but I have to agree with the choir here, too much bell. Those cases almost look like they're rolling back on themselves!

I think that batch of bullets have a larger diameter than previous batches.   The lead may be larger, or the coating thicker.  I stopped using coated bullets all together, because of the variability issues.

 

BTW, the bell I use is microscopic.  I get a better crimp that way.

What happens if you place them manually?

If I just gently place them by hands, they fall off the case when the shell plate rotates.  If I push a little bit into the case, they won't budge at all.  I remember previously these bullets are stuck into the case pretty hard.  The only thing I did recently was to take apart the whole press including the MBF dropper to clean it.  After I put everything back together, MBF starts to have this problem.  I suspect there is a setting on the MBF dropper tube somewhere to make the dropper push the bullets down harder.  Just not sure what I did when I originally set it up 3 years ago.  Maybe the 3 steel balls should go to the upper holes vs. the lower holes I now use?  Maybe the aluminum tube should be lowered further towards the shell plate?

I am pretty sure the bell opening does not have much to do with the issue, maybe a little bit. 

 

I remember previously I had even bigger bell opening, and I had to pull really hard to get the bullets out of the case from station #4, sometimes even when the bullets are upside down.

Have you tried another bullet type ?   One with a straight edge rather than

cut out so severely at the bottom ?

Also try the Spill Stop locator pin replacements from Reloading Innovations.  They will help to reduce the plate "jump" which can jostle even a properly seated bullet.

Looks to me like way too much flare.  Might dial that back and then use a spill stop as suggested by cbrconst, which stops the case from rocking as much while indexing.

Check to see if the ball bearings, in the dropper assembly, are in the correct holes for the bullet you are using?

Or you can use zip ties.

 The OP is using a 650. Even at 900 RPH with a M7 auto drive on my 650 I didn't have a bullet tipping over problem. But, with 650s there's a whole lot of aftermarket options to help make the press smoother as it indexes.

 

Look at his bell and brass expansion, the bullets really have nothing to sit in and support them.

When you re-set the Bulletfeeder did you have cases in all the stations?
