What’s In the Box

The Frankford Arsenal M-Press comes complete with the following:

  • Press assembly
  • Handle (shown installed)
  • Power adapter and micro-USB cord for integrated LED light
  • Three die blocks and die case
  • Instruction book (my early production sample did not have one, I instead got an electronic copy from Frankford Arsenal)

Assembly and Setup

Assembly and setup couldn’t be easier (really). Here’s all you have to do:

  • Slide the handle into the press frame, tighten set screw
  • Plug power adapter into wall, plug cord into power adapter and press (on the back)
  • Mount the press to your bench or stand/mount

I chose to adapt a generic Inline Fabrication Ultramount Quick Change Plate #45 for use with my Micro Ultramount since these plates aren’t yet available from Inline Fabrication. Drilling and countersinking the plate was quick work with my Precision Matthews PM-949 because I have a DRO! In a short period of time, I completed the quick change plate fabrication and installation, and was ready to roll! Here’s a view showing the M-Press on the Micro Ultramount:

And here’s a diagram showing the hole pattern and press footprint: (from the pre-release manual, subject to changes)

Unique Features

There are several features on the Frankford Arsenal M-Press that are worth noting! I’ll show you some of these features here. The first would be the integrated press light- I haven’t seen this on another press! There’s even a nice switch on the press that stays “down” when the light is on, and pops “up” when the light is off:

Another unique feature is the universal shellholder plate system. There are two circular discs under a metal plate which spin and “index” in 90 degree intervals. There are cutouts on these discs for small, large, 223, and 308 case rims. You can accommodate pretty much any reloadable cartridge up to and including 338 Lapua with this system! From the pre-release owner’s manual:

The way this works is: you slide the disk away from the center of the press (see middle arrows in diagram) and then rotate to a new position while sliding the plate back to the center of the press. The plate will “snap” into position for each of the four “quadrants”. Here’s what the shellholder plates look like set for a 308 case rim:

I found this system to work quite well. When loading, you set a case onto the base plate, and when you lift the handle, the shellholder plates move towards the case and clamp it in a centered position, ready for the case/cartridge to enter into the die above.

Another unique feature of the M-Press is the die block system. Hornady has Lock-N-Load, LEE has Breechlock, FORSTER has special die rings, and now Frankford Arsenal introduces the “die block” system:

These die blocks are essentially thick rings with a set screw, and a flat front. If you buy a set of die blocks (3 die blocks per set) a handy case is included which fits the dies and die blocks together. This can be an issue with other die sets (LEE Breechlock and Hornady Lock-N-Load as examples) – these dies don’t fit into some die boxes with bushings installed.

You can also toggle this press from “cam over” to “positive stop” operation (as shown in the video) by flipping the side links. This is nice because you have the option to operate the press either way.

Initial Test Results

For testing, I decided to size brass and seat bullets for both 223/5.56 and 308 Winchester (actually, 7.62x51mm military brass). I wanted to evaluate the leverage and relative forces involved to size brass, test the robustness of the universal shellholder, and see what kind of concentricity would be possible when seating bullets.

The press worked really well- its operation is very smooth, and the leverage it produces is great. 5.56 cases sized very easily with lanolin lube, where military 308 cases were a bit tougher (I used a small base die to put this press to the test) using the same lanolin lube. Setting up dies is very smooth, and I like the way that the die block set screw is ALWAYS facing you- so you can easily tighten/loosen it without “hunting” for it around the circumference of the die area. Seating bullets was super-easy as expected, and the concentricity was good.

Here are the results for the concentricity testing:

  • 5.56 brass with 70 grain Nosler RDF bullets, Redding Competition Seater die: +/- ~0.001″ (0.002″ TIR)
  • 7.62x51mm brass with 155 grain Hornady A-Max bullet, RCBS standard 308 seater die: +/- ~0.002″ (0.004″ TIR)

Some were nearly dead-on (zero runout). The 5.56 results are great, and I think the military 308 results could definitely improve with match quality brass and a competition seater die. I thought it would be good to test multiple die sets!

Frankford Arsenal M-Press and Forster Co-Ax Side By Side

The first thing people asked for when I announced content related to the Frankford Arsenal M-Press was a comparison to the Forster Co-Ax, so here it is!

These presses may have a similar action when you run them, but there are quite a few differences!

First the similarities:

  • Cast iron construction
  • High-leverage design

And the differences:

  • Frame: Co-Ax has central frame, where M-Press us supported by guide rods
  • Capacity: M-Press has about 5″ where the Co-Ax has about 4 1/4″ (both will have less usable capacity due to die protrusion which will vary)
  • Light: M-Press has one, where the Co-Ax does not
  • On-Press priming: Co-Ax has it, where M-Press does not
  • M-Press does not hang down below bench, where Co-Ax does (both will have the handle swing below the bench if mounted flush to benchtop)
  • Camover toggle: M-Press has it, where Co-Ax does not

In the end, you’ll need to look closely at each press and decide which one would be better for you. I’m hoping that the information I provide here on Ultimate Reloader will help you make these kinds of decisions!


The Frankford Arsenal M-Press is new for 2019, and should be available sometime in February or early March 2019. I’ll keep you all posted!

  1. Just wanting to start reloading and the m press really impressed me. Will just have to wait on it. Just one question: can you reload pistol and rifle ammunition with the same press?

    1. Yes you can. Reloading pistol rounds usually requires less effort on your part since they usually operate a lesser pressures than rifle rounds..

    2. I reload 223 and 9mm. It’s not the press, it’s in the dies. You have to have a set of dies for each caliber. Good luck!

  2. Do you have any idea of when they’ll hit Australian shores? Been hanging out to hear any news but no one seems to know… Cheers.

  3. Hi enjoyed your video on the new m-press and have a couple of questions is it suitable for the 45/70 govt round also will it accept the lees precision pacesetter dies and finally did see in the video you trimming the cases after sizing so will it accept the lee deluxe trim tool and quick trim die.
    Thanking you in advance

  4. Hey Gavin, I enjoy your videos and have been watching for a few years now. I’m especially interested in the Co-Ax presses and was wondering if you could answer a couple of questions for me. First, do both presses accept the 220 Russian type cases in their shell holders?, and second, which press do you recommend overall? They both have features that I like. If you can offer any info in regard to my questions I would greatly appreciate it. Thanks in advance.

  5. Thanks Gavin for the detailed operation and overall review. I’m always on a budget, I just got into reloading just over a year ago and started with the Lee 50th Anniversary Classic single stage kit. I’ve been looking into this press, for a month or so. prior to this one, I was looking into the new MEC press. The only down fall is the on press priming. but I can always use the Lee press for that or buy a handheld priming tool.

  6. Hi Gavin!
    Would you recommend this press as a ‘starter’ press? Found one locally for sale used (very little!) and it is an intresting design. I am leaning more toward a turret style since I feel having all dies setup would be faster and easier. Thoughts?
    (Would be 357 Magnum at first and likely. 308 Win to develop a ‘perfect’ load for my precision rifle. But honestly I don’t shoot a ton (but would/should!) and a big part of reloading that appeals to me is the mechanical, craftmanship part of it. And I guess in the end save a few bucks. Maybe…)

  7. Hi Gavin, looking to get into reloading 300WM. Found this M-press on sale for about 135 which seems like a good deal. I was wondering if you had any insight into why it is on such a sale? Would this press be a good candidate for reloading 300WM?
