Mr Bulletfeeder Replacement Dropper Ball Bearing Size?

Recommended Posts

Lost a ball out of the dropper assembly and took one of the others to local industrial equipment supplier to find some replacements.  When attempting to install the new ones I lost the only remaining original ball.....which wouldn’t have been a problem except the replacements are too large and don’t fit into the die. 

 

Can someone confirm the ball size is 4mm?

 

I failed to specify metric upfront so if anyone needs approx. 150  3/16 chrome alloy grade 25 balls send me your address!

I have an email from Rick from 2017 wherein he describes these as 4.5 mm in size.

 5.56/.223: 6mm ball bearings
- 7.62/.308: 5mm ball bearings
- 9mm/38: 4.5mm ball bearings
- 10mm/0.40: 4.0mm ball bearings
- 0.45: 3.5mm ball bearings

 

 

How did I not find that first place I checked was their website 

 

thanks Greg
