outerlimits Posted January 5, 2017 Share Posted January 5, 2017 anyone out there using mr bulletfeeder conversion kits to change from pistol to rifle calibers? was wondering if it is worth the time and cost vs a dedicated press for rifle caliber?

rowdyb Posted January 6, 2017 Share Posted January 6, 2017 I just got a MrBF conversion kit for Christmas but haven't installed it or used it yet. I load on a 1050 so I don't make a change to a different caliber until I know I'm going to make a big run of it. So I'm curious to know as well.

Steve_53 Posted January 6, 2017 Share Posted January 6, 2017 (edited) I switch mine (mounted on an XL-650) back and forth between .45 ACP and .223. I have dedicated toolheads for each caliber, so there is no re-adjusting of the bullet dropper die. I have made a set of "shim gauges" to set the nose guide for each of the bullet profiles I use, so the change-over of the Mr. Bulletfeeder adds only about a minute to the caliber swap time. I simply change the collator plate and the output spring assembly (rifle uses the small diameter spring, pistol the large diameter one), and reset the nose guide after I have swapped the toolheads, shell plate, primer mechanism, and the casefeeder parts on the XL-650 (all told, less than 10 minutes).

cvincent Posted January 6, 2017 Share Posted January 6, 2017 Same as Steve. I leave the droppers and output springs on the tool heads and just remove from the collator. Less than 10 mins to change everything from .40 to .223. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
bwikel Posted January 6, 2017 Share Posted January 6, 2017 I also remove the spring from the collator and it stays with the caliber dedicated tool head. I use watermarks on the flipper adjustment so I can move right to the optimal place without any tweaking. The MBF changeover for me is less than 1 min.

I switch back and forth from .223, 9mm, and .380 all the time. I use dedicated tool heads, except for .380. I doesn't take a great deal of time, even if you are doing a total swap, like between 9mm and 380. I find that setting up for different bullet nose profiles is sometimes a bit more challenging. (usually .355 hollow points) I've also found that the small diameter spring (rifle) works best for the light .355 bullets. BRC Link to comment Share on other sites More sharing options...
