Mr. Bullet Feeder: Next Step in Press Evolution

Redding Big Boss II single stage press

I have mentioned the Mr. Bullet Feeder (MBF) in my post about the Dillon XL650 progressive reloading press but I feel that the device deserves its own post. It is a product that while obviously working as a part of something larger is in and of itself a remarkable achievement.

For those who started on single-stage reloading presses, the move to a turret press (where multiple dies can be rotated for use above a single case) is a big improvement. It allows the reloader to perform all the reloading steps within a relatively short period of time.

Lee Turret Press

A true progressive press is similar to the turret press. It too has multiple dies in a tool head. The big difference is that the progressive press keeps the dies in place and has the cases move under them sequentially on a rotating shell plate, thus allowing multiple actions with each pull of the handle. Consequently the rate of round production goes up by a factor of X, where X is the number of stations (case/die positions) on the shell plate. With simpler progressives, the reloader still has to perform all the same actions as with the turret press, unless the press is designed to automate additional functions.

As press design improved and reloaders wanted more and more automation we got things like the automatic primer and automatic powder feeders, the latter being a huge time saver. Measuring out precise powder loads is of course essential for reloading and once that became automated it really sped up the process. The Dillon 550 press is a great example of a 4-station press that had all these features but it still required manually placing a case in the first station of the shell plate, manually indexing the plate to the next position after each stroke and manually placing the bullet on the case prior to seating and crimping. In the last year or so Dillon has in fact began producing an automatic case feeder for this press so it can be said that the operation can be done without taking one’s right hand off the handle, but the left hand would still have to index the plate and place the bullet.

I’ve already discussed the Dillon XL650 so rather than belabor the point I will simply say that it adds a fifth station and automatic indexing to the already-impressive functions of the 550B. With the 650’s optional case feeder installed this leaves only one task for the left hand: placing the bullet.

As you can see in the picture of the 550B, there is a tray on the left side of the press for placing bullets. This allows quick retrieval and placement of the bullet after each stroke. Many people find this to be a great way to reload. Rounds can in fact be produced very quickly using this setup. Nevertheless, many of us opt for the next evolutionary step in automation by installing an automatic bullet feed system. Once you’ve tried it the system is irresistible .

There are several manufacturers of bullet feeders but the one that has arguably the best reputation is the Mr. Bullet Feeder. I had used the one Glyn has on his Dillon Super 1050 so I knew how much it increased reloading efficiency. When I started using my XL650 without it I realized immediately that my setup wasn’t nearly as quick and efficient. It wasn’t long before I bought one for myself.

The kit for the XL650 comes with a PVC base that holds the main portion of the device (bullet hopper w/ collator plate, motor, guide plates and bullet tube) and this is attached to a simple but very effective bracket that attaches directly to the case feeder support tube. Included in the kit are replacement bolts to accommodate the additional thickness from the added bracket.

The other component of the system is the bullet dropper assembly, which is mounted as a die in the tool head. This device holds a stack of bullets sufficient to produce the downward force necessary to place a single bullet firmly on each case as the case is raised up into the bottom of the dropper. The dropper also houses a sensor switch that tells the collator motor to run when the stack is short. I in fact had a failure of this switch but one quick email later and Rick had the replacement on its way. Gotta love that kind of customer service!

This system takes up no additional space on the reloading bench, is not in the way on the press and perfectly places a bullet on every case that comes by. I purchased kits for 9mm, .45acp and .223. The bullet droppers stay mounted in their respective tool heads so switching calibers takes about 2 minutes longer than before the MBF. You do have to 1) change the collator plate (just like the case feeder), 2) change a small guide plate next to the exit tube on the collator and 3) depending on the caliber, you might need to swap out the tube that connects to the bullet dropper. Very simple.

A reasonable question at this point is “why not put a motor on this thing and reload while you take a nap?” The reloading process as we private reloaders practice it is one of subtleties. The act of pulling the handle not only produces the force that does the reloading but it also provides us sensory feedback as to what is happening within the press. As I pull the handle I know at each point in the stroke what I should feel during a normal pass. If something feels wrong, it probably is. The most common problem is with primer feeding. I know immediately if the primer didn’t seat correctly so I pull that case out of the press and discard it. This would not be possible with a motorized press.

As for the Mr. Bullet Feeder, I couldn’t be happier. The instructions are good, the installation easy and the performance outstanding.


NOTE: In my original post on the Dillon XL650, I mentioned the following regarding where to mount the MRBF:

“Given that the bullet feeder requires a station and the fact that I wanted to use the powder check die (seeing a pistol go kaboom is an eye-opening experience) I got hold of an RCBS seat/crimp die for station five. I have found this to be an ideal setup for 9mm.”
