Product Information

No need to complicate the reloading process. The Co-Ax® Reloading Press keeps it simple while still delivering famous Forster precision.

The Forster Co-Ax® Reloading Press comes with several unique features that help make it truly one of a kind, including:

Snap-in and snap-out die changing. You can actually change from sizer die to seater die in two seconds!

  • A positive spent primer catcher system which passes all spent primers and dirty carbon through a tube and into a container. That helps keep all working parts free of dirt and abrasives.
  • Dual floating guide rods to help ensure perfect alignment.
  • Because there is absolutely no torque on the head of the Co-Ax® Reloading Press, long life is the rule rather than the exception. Due to the design of the linkage and pivots, all forces are in equilibrium whether the press is at maximum work load or at rest.
  • Our Co-Ax® Reloading Press has three times the mechanical advantage of an ordinary "C" press. It's so effortless, full length sizing can actually be accomplished by operating the handle of the press with the little finger! There's no pain but plenty of gain.
  • The Co-Ax® Reloading Press delivers perfect alignment of the die and the case because the shell holder jaws are designed to float with the die, thereby permitting the case to center precisely in the die.
  • With no frame supports or swinging primer arms to interfere or cause an obstruction, the Co-Ax® Reloading Press provides plenty of elbow room for both right handed or left handed operators.
  • The Co-Ax® Reloading Press accepts any standard 7/8" X 14 reloading die, some with existing locking rings. We recommend Forster Cross Bolt Die Lock Rings.
  • The unique top priming device seats primers to factory specifications. The seater is always at right angles to the case head. Primers will not flip or tip. They will be seated straight, level and at a uniform distance below the case head. Primers cannot be crushed, nor will they protrude from the case head and cause premature firing.
  • The top of the stroke provides a rock solid stop for consistency.
  • Includes “S” jaws to fit most calibers. “LS” jaws are available separately.

Love my Co-Ax

By Stephen A. on Feb 12, 2024
I have been reloading on a Lyman Orange crusher since I was in high school (wasn't a one room school house but it has been a LONG time) and honestly never thought about replacing it till a friend showed me their CoAx press. Wish I had done this sooner, loving this press so far! I will be adding the replacement curved linkage plates but that is a minor thing that I can take care of very soon.

I have been sharing one of these with my father for years and finally got one of my own.This is a great press that will live up to all the positive reviews it gets.Thank you Graf & Sons for great pricing and fast free shipping.

As Advertised!

By Grant M. on Jun 07, 2023
Great press. Love not having to use shell holders and not needing to screw/unscrew dies. Excellent leverage for sizing.

The best Rest for your money

By THOMAS C. on Jan 10, 2023
I have been reloading since back in the 60's and have owned just about every press out there, single stage and progressive . It took me 60 years to buy this one , don't make that mistake , it is the BEST , I don't know why I didn't buy one sooner . The price was great and shipping was fast .

There's a good reason why this press is so incrediby popular

By Scott C. on Aug 22, 2022
Having spent over thirty years using my beloved RCBS Rock Chucker, I had few gripes, turning out quality ammo well up into the tens of thousands of rounds in that time, but there were a few things about it that made me tempted for many years to finally drink the "Red Kool-Aid."
The Rock Chucker is the popular favorite, and I still love it, but I never really cared for the spent primer collection occasionally dropping primers onto the floor and scattering the very abrasive primer debris into the ram and linkage of the press. quali
I also have very large hands, and it is just a bit awkward inserting and removing cases through the O-type opening of the Rock Chucker.
I broke down and ordered the Co-Ax, and I have to say that it really is amazing how a press that had its last major revision clear back in 1968 could have gotten it so right after all these years.
The quality of construction and rigidity are as good as anyone could ever hope, and (one small thing) I really appreciate little touches that most people would mention, such as the fact that the press is secured with four bolts instead of only two.
The stock press is excellent, but I went ahead and added one upgrade to it, the Inline Fabrication roller handle, and that turns an already excellent press into something so ergonomic and easy to cycle that even a toddler could run it with ease full length resizing .30-06 brass.
What's not to like: A much more open access to where the brass is inserted, universal shell holder jaws that make case insertion easier and do away entirely with conventional shell holders, the floating shell holder jaws and slide-in dies that also float to allow the case to self-center while being sized and having bullets seated, and the basic straight up and down ergonomics of the lever.
I look forward to churning out tens of thousands of more rounds of ammo on this press, and this time I'll have a much easier time doing it, and it has already made reloading fun again.

Forster CO_AX press and more.

By Scott J. on Apr 01, 2022
I am happy to find the Forster CO AX at Graf & Sons but I have been even more excited to have found Graf & Sons. The prices are fair, more than fair but more than the press and the prices Graf & Sons has the secret sauce. They have something that has to come from the top down and must be instilled in their organization and that is great customer support and great follow up. These are the things that keep me happy and returning to Graf and Sons.
I trust Graf & Sons and will continue supporting their business. Your my go to place for anything gun or ammo related.
Thanks to your entire team.

Forster Co-Ax

By Raymond S. on Oct 24, 2020
This press is excellent, it took a while to find one in stock but it was worth the wait, it was every penny too. I use it for precision loads while my old single stage is still mounted and setup for plinking ammo. I would highly suggest this if you are looking for a solid press that can do it all.

Best Single Stage Press Ever!

By Helbert C. on Oct 16, 2020
This was my second press and once I received it and was able to start reloading. I told myself this should have been the first press I purchased. It's the perfect size and weight. So glad I was able to find it here at Graf's & Sons for a great price.

Graf’s is awesome

By Rick G. on Oct 15, 2020
My first press and I chose the right one! This thing is easy to work, set up and produces quality products ... 👍👍

Forster CO-AX B-5

By Kyle M. on Aug 10, 2020
Just started Loading for PRS. I am super happy with the performance of the Forster CO-AX. The S Jaws make it simple. I like the setup and ability to line up to improve concentricity

Best Press Out There

By Bryce H. on Jun 17, 2020
No other press compares to this one.

Forester co-ax press

By Richard K. on Jun 12, 2020
The best ... high quality ... very strong. I have purchased 3 since 1985... 2 as gifts. Expensive but a good value. Easy to use ... produces precision reloads. Have owned Herters, Lyman, Lee & RCBS presses, but prefer the CO-AX by far.


By Herbert M. on Apr 24, 2020
What a jewel. Not only does it create extremely consistent ammo, but the effort it takes to set up and use is much less than the other two presses i've gone through. Just buy it!

This is my 5 press and I love it.

By Donald E. on Apr 18, 2020
My 1st step up was RCBS Summit which i still have it’s a nice press but it’s not a co ax. I started with the RCBS jrII and had a Lyman 6 stage. This Forster co ax is worth the hype, it is so smooth. Every time I walk in the reloading room I smile with pride looking at my co ax. There is a reason they are back ordered everywhere.

Just order one!

By Jason F. on Apr 18, 2020
I load on a Dillon 550, & a RCBS R/C. This Forster press is super smooth & compact, & worthy of all the hype it receives. I will now use my R/C as a dedicated bullet puller only! I outfitted mine with everything Inline Fabrication has for the Co-Ax & it couldn't be better now.

Great Single Stage Press

By Richard N. on Mar 04, 2020
I have owned many presses over the years and the Forster Co-Ax is very impressive. I use it for some heavy duty re-sizing and it is easy to setup, easy to change dies, and results in accurate cases due to the self-alignment.

I like everything about it!!

Hard to get for. a reason!

By Chris C. on Feb 25, 2020
Well worth the wait. It is so much faster and more precise for switching calibers.

Forster coax press

By Jarried C. on Jan 29, 2020
By far the best and most accurate single stage press I own. I have had 3 rcbs rockchuckers, still got 2 of them also own a dillon. They will never seat another bullet as long as i own them. I bought the coax for it's positive stop design, which makes it excellent for seating bullets with a micro die. Every bullet I have loaded with the coax is within 2 10th of one thousandth. That is fantastic consistency! My rockchuckers cant hold 1 thousandth. I now have two coax and may have a third before it over. Best money i have ever spent on a press!

Believe the Hype... Worth the Wait

By Mike H. on Nov 04, 2019
This is my first single stage press so I don't have anything to compare it to, other than my "Blue" progressive press - which I really like as well. I was looking for as much precision as "I" could muster. For 6.5 Creedmoor precision loads, I now use the progressive for brass prep and this beauty, for consistent primer seating and, along with the Forster Micrometer Seating Die, bullet seating to 1/2 thou. Very happy with the setup.

Excellent Press!

By Jeremiah H. on Sep 18, 2019
I could not be happier with this press. The fit and finish are amazing . Everything is tight no slop anywhere. Money well spent!

Precision press

By Richard H. on Sep 12, 2019
I upgraded to the co axe recently and couldn’t be more impressed, I have a Hornady and a lee press that I’m just gonna use for recapping and swagging primer pockets. The leverage you get from the co axe is beyond compare, the dies and shell holder kinda float for precision alignment in bullet seating operations, I would highly recommend the Forster dies to go with it, if you want precision ammo, don’t hesitate to buy one, if it’s stock.

Forster Co-Ax single stage press

By Donald D. on Sep 10, 2019
Great product! It lives up to the hype!

Love my Co-Ax

By Butch C. on Sep 06, 2019
A friend of mine tried to talk me into buying a Rock Chucker, well I am so glad I did not listen. When I set up the Foster Co-Ax, he came by to check it out. Well all it took was one time full length resizing 6.5 Creedmoor brass. He could not believe how much leverage it had, and the ease of changing dies once set. He is about to order him a Co-Ax. I love it.

Simple and accurate

By Dave K. on Jul 29, 2019
What more can you ask for? Nothing!


By Frank S. on Jul 29, 2019
I use to think my trusty Rock Chucker was the holly grail of presses. Then I found the Redding T-7. Well there's a new sheriff in town now that makes my other two presses wonder why they don't get any love anymore. My Chucker is nothing but bullet pulling duty now and my T-7 had pistol duty. But for all my rifle loading its nothing but my new Co-Ax. What an engineering marvel. It is by far both Top Shelf and award winning with .001 - .002 run outs. And I can't say enough for Graf & Sons either. I will be doing more business with them in the near future but folks, buy this press and give Graff a shot at it.

Forster CoAx

By Alex T C. on Jul 01, 2019
So glad I pulled the trigger and took advantage of Graf & Sons price and availability for this press. I have used a Rock Chucker for 40+ years along with an arbor press. They still will have small places for a very few jobs but for the lions share of my center fire reloading I have a great new tool.

This thing is Sweet !!!

By James S. on Jun 28, 2019
I really got lucky and found Graf's had a few in stock. After reading all the great reviews, i got on all the distributors and
waited. Forster said they are making these presses as fast as they can.
Get in line and get you one. Graf's shipping and packaging was great, arrived with no damage. I love Graf's.

Excellent Press

By Michael J. on Jun 06, 2019
I couldn't be happier with this purchase. I love the shell holding feature on the co-ax and how the co-ax retains the dies. This press also requires minimal effort in the resizing process.

What a difference!

By Kent P. on Apr 05, 2019
I tried some other single stage presses, and this is by far the best in my opinion. Very low effort required.

Great press!

By Lester W. on Mar 22, 2019
I've been reloading with a Rockchucker over 40 years. This press requires much less effort. I also really like the universal shell holder. It lets your brass float along with a floating die. This promotes a loaded round with very little run out.

Best Single Stage Press

By Michael S. on Mar 21, 2019
You will not find a better single stage press! I use this press for precision rifle loading! Graf & Sons offered me a great price and fast shipping.
