“The press is the heart of the handloading operation, also traditionally the most expensive single tool employed…” — Laurie Holland
British competitive shooter Laurie Holland has reviewed three popular, single-stage reloading presses for Target Shooter Magazine (targetshooter.co.uk). Laurie bolted up a Forster Co-Ax, RCBS Rock Chucker Supreme, and RCBS Summit to his reloading bench and put the three presses through their paces. These three machines are very different in design and operation. The venerable Rock Chucker is a classic heavy, cast-iron “O”- type press that offers lots of leverage for tough jobs. The smaller RCBS Summit press is an innovative “upside-down” design with a large center column and open front. It offers a small footprint and easy case access from the front. The Co-Ax is unique in many respects — dies slide in and out of the upper section which allows them to “float”. The cartridge case is held in the lower section by spring-loaded jaws rather than a conventional shell-holder.
If you are considering purchasing any one of these three presses, you should read Laurie’s article start to finish. He reviews the pros and cons of each press, after processing three different brands of brass on each machine. He discusses ergonomics, easy of use, press leverage, smoothness, priming function, and (most importantly), the ability to produce straight ammo with low run-out. The review includes interesting data on case-neck run-out (TIR) for RWS, Federal, and Norma 7x57mm brass.
Review Quick Highlights:
RCBS Rock Chucker Supreme
“My expectations of the antediluvian RCBS Rock Chucker Supreme’s performance weren’t over high to be honest as I mounted it in the place of the Summit. As soon as I sized the first of the stretched RWS cases though, I saw why this press has been such a long-running favorite. The workload was considerably reduced compared to the other two presses and doing 40-odd cases took no time at all with little sweat — it just eats hard-to-size brass.”
RCBS Summit Press
“Despite its massive build and long-stroke operating handle, [the Summit] took more sweat than I’d expected, even if it was somewhat less work than with the Co-Ax. Although the Summit is apparently massive, I noticed that the die platform would tilt fractionally under the heaviest strains[.] It is nevertheless a very pleasant press in use and bullet seating was a doddle — the few examples tried proving very concentric on checking them afterwards. The optional short handle would be valuable for this task.”
Forster Co-Ax
“[On the Co-Ax], the operating handle is above the machine, located centrally [with] twin steel links at the top end of the press dropping down to the moving parts. The Co-Ax incorporates [many] novel features, principally its automatic and multi-case compatible shell-holder assembly with spring-loaded sliding jaws, very neat spent primer arrangements that allow hardly any gritty residues to escape and foul the moving parts and, the snap-in/out die fitment that allows rapid changes and lets the die ‘float’ in relation to the case giving very concentric results. I own this press and it meets my handloading needs very well.”

A Short History of RCBS (And the Origin of the “RCBS” Name) RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. Huntington was a dedicated shooter but found it difficult to obtain quality varmint bullets. However, after reading about making a die to swage .22 rimfire cartridge cases to form jackets for bullets, he began to craft his own dies in the back room of his father’s Oroville laundry and dry-cleaning business. Because the resulting bullets were used to shoot rock chuck varmints, he named them Rock Chuck Bullet Swage dies, later shortened to RCBS.
RCBS soon outgrew this modest beginning. By 1958, RCBS expanded to a 7,500-sq-ft factory that quickly grew to 50,000 square feet. With time, more expansions have occurred, but RCBS stayed near its roots. Oroville is still the major location for RCBS production. RCBS is now a subsidiary of Vista Outdoor, which also produces Federal and CCI ammunition and primers, Alliant powder, and many other products.

Gear Review by Mark LaFevers With its innovative “moving die/static cartridge” design, the new RCBS Summit Press definitely demonstrates “out of the box” thinking. Unlike other presses, the case does not move. Rather, the reloading die comes down to the case. We are happy to report that this unique “upside-down” reloading press works great.
We have tested the new RCBS Summit Press in the workshop and in the field. We’ve now loaded hundreds of rounds with the press. It is smooth, solid, and easy to use. The spent primer ejection/capture system works great (our testers preferred the Summit’s simple, foolproof primer capture to the Rockchucker’s capture system). Most importantly, the Summit produces very straight ammo that gave excellent results on the target in actual matches.
We compared ammo loaded with the Summit with ammo loaded on an RCBS Rockchucker press. The Summit gave up nothing to the bigger press. Cartridge base-to-ogive measurements of Summit-loaded ammo were just as tight as with ammo loaded on the Rockchucker. Run-out, measured with a concentricity gauge, was the same or better (about .002 or less on bullet nose). Most importantly, the Summit loads accurate ammo. In fact, at one match, scores shot with Summit-loaded .284 Win ammo were actually better than scores shot (in the same gun) with ammo loaded on a Rockchucker:
Despite its small footprint, the Summit is very stable — it doesn’t tip, wobble, or rock. The two front mounting bolts hold it firmly in place — the Summit doesn’t need a rear anchor. This, combined with the fact that the Summit has no overhang, makes the new press ideal for a mobile application. For field use (at the range), our tester Mark LaFevers mounted the Summit press on a small platform secured to his trailer hitch (on top of a steel post). This set-up worked great, as you can see in the video below:

Mark tells us: “I think the Summit press worked out sweet mounted on the hitch pedestal. The receiver hitch pedestal I made will switch tools between a heavy barrel vise I made and the Summit press. Instead of securing the pedestal with a standard 5/8″ hitch pin, I drilled and tapped for 1/2″-13 bolt to draw the insert up tight against the receiver, eliminating wobble. For charging rounds, I bought 150 plastic test tubes with caps and racks so I can avoid weighing powder charges in the field, unless I want to make changes on the fly.”
The new Summit Press features a rugged cast-iron frame with all-steel linkages. The press is very strong with minimal flex and slop. This allows you to “bump” your case shoulders and seat bullets with great precision and repeatability. The handle can be switched from right to left side (good for southpaws), and the open-front design provides good access, facilitating quick die changes*. The 4.5-inch opening allows you to work with tall cases. Beneath the shell-holder is a spent primer catcher (not shown in photos). The new Summit press has a beefy 2-inch diameter ram, with compound linkages for plenty of leverage. A zerk fitting is included for easy lubrication. The press will accept larger bushings for oversize 1-inch dies.
*To permit his dies to be swapped from Rockchucker to Summit (and back again), with no locking ring adjustments, Mark LaFevers fabricated a new shell-holder base which positions the shell-holder .088″ higher relative to the Summit’s die port. This keeps Summit-mounted dies in the same position relative to the shell-holder as dies mounted in a Rockchucker. So, Mark can swap dies from his Rockchucker to his Summit and maintain exact COAL (when seating) and correct shoulder bump (when sizing). While Mark’s custom shell-holder base lets him swap dies quickly from one press to another, this is NOT a necessary modification. Most folks will simply re-set the locking rings.

The new RCBS Summit Press attracted a lot of attention when we first revealed it in the Daily Bulletin earlier this month. Readers wanted to know how well this radical new design really worked. To answer that question, we headed to the RCBS booth at SHOT Show 2013. There our buddy Kent Sakamoto gave us complete run-down on the new Summit. With the Summit, unlike other presses, the case does not move. As you can see in the video, the reloading die comes DOWN to the case.
The Summit’s open-front design is definitely a plus, and we really like the fact that all press operations take place ABOVE the benchtop. There are no linkages running below the bench, which lets you use the Summit on a bench with cabinet-style drawers. The Summit press is definitely beefy. With its massive center column, the design operates smoothly with no flexing issues. RCBS says the Summit has no more head flex than the classic “O”-design RockChucker.
The new Summit Press features a rugged cast-iron frame with all-steel linkages. The handle can be switched from right to left side (good for southpaws), and the open-front design provides good access, facilitating quick die changes. The 4.5-inch opening allows you to work with tall cases. Beneath the shell-holder is a spent primer catcher. The press will accept larger bushings for oversize 1-inch dies. Street Price in the new Summit Press is about $220.00 (optional Short Handle is another $19.95).
