GregJ Posted February 14, 2018 Share Posted February 14, 2018 For those that have done the caliber conversion from 9mm to 45ACP, did you also have to adjust the MBF spacers and ramp to feed the 45s? In the near future I will be going from 124gr RN Zeros to 230gr RN Zeros, and curious what additional adjustments/tweeks I can expect. TIA Link to comment Share on other sites More sharing options...
Steve_53 Posted February 19, 2018 Share Posted February 19, 2018 Yes, pretty much any change in bullet shape, especially diameter, will require a ramp adjustment. I run my Mr. Bulletfeeder with 230gr .RN 45's, 160gr .RN 38's, and 55gr .BT 223's - for all three calibers, I am using (the same) 2 shims. Once I got each setup dialed in , I made a 1" wide aluminum "gauge" that matches the thickness of the gap between the bottom of the ramp and the adjustment slot of the collator for that bullet (and made sure that I labeled them ) - makes switching from one to another quick and painless.

Steve_53 Posted February 22, 2018 Share Posted February 22, 2018 Pictures (as requested)-"gauges" made out of odd aluminum scraps, relative thicknesses, and in-use. Link to comment Share on other sites More sharing options...

GregJ Posted February 24, 2018 Author Share Posted February 24, 2018 I didnt have alum scrap thick enough, so I found some plastic wedges at HD. Insert from the bottom and mark a line on it for that cal. I also scribed lines on the bottom on the housing and the black plastic ramp. Link to comment Share on other sites More sharing options...
