Hand-loaders have never had so many great choices in single-stage presses, with many different configurations and features. There are classic O-Frame presses, Coax-style presses, Open-front presses, Pyramid presses, and compact C-Frame presses. Here is our 2019 Single Stage Press Showcase with products from Forster, Hornady, Lee, Lyman, MEC, and RCBS. We’ve included short videos showing the features of these reloading presses.
If you are shopping for a new press you should look at the various features of each. You may prefer something classic like a Rock Chucker, or the innovative open-front MEC. If you are looking for a compact press to use at the range, the Lyman C-Frame is very impressive for the price. And the Forster Co-Ax remains a great addition to any loading room.
MEC Marksman Single-Stage Press
If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. With a $245.49 street price, the MEC Marksman press now costs more than an RCBS Rock Chucker Supreme press, but the MEC offers some distinct advantages — such as an open front plus a floating shell-holder system.
Our friend Gavin Gear of UltimateReloader.com got his hands on a MEC Marksman press and put it through its paces. He came away impressed with the product, saying it delivers excellent performance, and has many impressive features. Gavin tells us: “Cast iron tools and machines are a lifetime investment. The made-in-USA MEC Marksman features ductile cast-iron construction, an open-front frame design for easy cartridge access, a new floating shell-holder design with a unique retention system, and ambidextrous handle setup.” MEC also offers a wide selection of accessories for the Marksman press, including a press riser/mount, shell-holder caddy, and die trays.
Forster Co-Ax Press
If you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.
In recent years, Forster Co-Ax® presses have been somewhat hard to find, as demand has out-stripped supply. The Co-Ax has many dedicated fans, given its unique features, such as the floating case-holder jaws, and easy, rapid slide-in/slide-out die placement. We’ve also found that Co-Ax presses load very straight ammo and we like the ability to switch between short handle (good for bullet seating) and long handle (ideal for heavy case-sizing tasks). We also think the Forster Co-Ax has one of the best spent primer capture systems on the market — a straight drop into a removable plastic cup. Simple and it works.
Lyman Brass Smith Victory Single-Stage Press
Lyman’s sturdy Victory Single-stage Press is a full-size unit that competes with the RCBS Rock Chucker Press. With beefy cast iron construction, the Victory’s strength and leverage rivals the Rock Chucker. The press operates smoothly and the handle can be mounted on either side.
If you like to prime cases using a press, this Victory press has a priming system that’s much easier to use than the RCBS Rock Chucker system. The priming tube is right up front, with multiple primers loaded vertically in a tube. Simply push the shuttle at the button of the tube to advance the primer into place.
For convenience, the entire primer-loading system can also be removed so it doesn’t interfere with case and bullet-handling operations. We generally prefer to prime cases separately using a dedicated hand- or bench-mounted tool, but the Victory press does the job nicely.
Overall, the Victory is a great value in a full-size “O-Frame” press with sturdy construction and a solid Lyman warranty. It is available now for $208.52 on Amazon.
RCBS Rock Chucker Supreme Single-Stage Press
Nearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.
Some people may not know that the Rock Chucker offers a secondary 1 1/4″ x 12 thread for shotshell reloading dies and Piggyback 3 upgrade. The Rock Chucker Supreme retails for $213.79 now at Powder Valley and qualifies for a $35 RCBS rebate, lowering your net cost to $178.79 (after rebate). The RCBS Rock Chucker is definitely a quality product that can last a lifetime. For heavy-duty sizing chores this remains one of the best choices in single-stage presses. This is a good time to buy a RCBS press with the current RCBS Rebate Program.
Lyman Brass Smith Ideal C-Frame Compact Press
The Lyman Brass Smith Ideal Press is a very affordable, cast iron C-Frame reloading press. We think it is the new “class leader” in compact presses. This works great as a secondary press for your reloading room or a small press you can take to the range. The large front opening allows you to access the shell holder without hitting the support bar on other types of presses. Unlike other compact presses made from aluminum, Lyman’s Ideal press is cast iron so it is rigid and strong. The high-quality steel ram is one inch in diameter. The Brass Smith is a true ambidextrous press that can be accessed from either side and mounted the same. This is a great choice for a second, auxiliary press for depriming and bullet seating. It is now just $119.66 at Precision Reloading.
Hornady Iron Single Stage (Open-front) Press
In this “Reloading with Rosie” video, the attractive female host loads some ammo using the Hornady Iron Press. With a beefy, pyramid-style cast-iron frame with an open front, this press offers some advantages over a traditional “O-Frame” type press. Access is considerably easier, for one thing. And the top of the press includes slots to hold dies and tools — that’s really a very nice feature that saves time. Also an optional “automatic” priming system shuttles primers from a vertical tube in the back to the shell-holder in the front. That’s clever. Over all the Iron Press is a nice piece of engineering — good job Hornady. It is offered for $314.78 at Precision Reloading.
Lee Classic Cast (Iron) Breech Lock Press
The Lee Classic Cast Breech Lock Press offers excellent value for the money ($190.99 at Midsouth). Based on the proven design of the Classic Cast press, the updated Breech Lock series adds the quick-change die bushing and an improved primer drop system. This press is strong, with cast iron frame, all-steel linkage, and 12 square inches of ram bearing surface.
Lee says this press has the “largest opening and the longest stroke in the industry” among O-frame type presses. The handle can be mounted on either side. We love the fact that the handle ANGLE can be adjusted, as well as the lever arm length — that allows you to adjust travel and leverage to suit your preference. Smart engineering.
The new spent primer drop features a large-diameter hollow ram with clear hose that drops primers straight to a bin — that’s simple and effective. The press is very rigid and the base is wide enough for good stability. We have one of these Classic Cast Breech Lock Presses in our reloading room and it works well.

This article comes from the Criterion Barrels website. It provides good, conservative advice about barrel cleaning. Understand that cleaning methods may need to be adapted to fit the amount and type of fouling (and the particular barrel). In general, we do try to minimize brushing, and we follow the procedures Criterion recommends respecting the crown/muzzle. We have also had very good success using wet patches followed by Wipe-Out bore foam. Along with the practices outlined by Criterion below, you may want to try Wipe-Out foam. Just be sure to use a fitted cleaning rod bore guide, to keep foam out of the action recesses and trigger assembly.
The above video shows how to apply Wipe-Out or other bore-cleaning foam. We use a slightly different method. First, we use 3-4 wet patches to remove loose carbon fouling. Then we apply the foam as shown, but usually from the muzzle end (with bore guide in chamber). Here’s the important point — after 20-30 minutes, once the bubbles have dissipated, we apply the foam a second time, getting more of the active ingredients into the barrel. We then patch out, as shown, after 3-4 hours.
What is the Best Way to Clean a Rifle Barrel?
We are asked this question quite frequently alongside requests for recommended break-in procedures. Improper barrel cleaning methods can damage or destroy a barrel, leading to diminished accuracy or even cause a catastrophic failure. When it comes to barrel maintenance, there are a number of useful techniques that we have not listed. Some techniques may work better with different barrel types. This series of recommendations is designed to incorporate a number of methods that the Criterion Barrels staff has used successfully both in the shop and on their personal rifles. Please feel free to to list your own recommendations in the below comments section.
We recommend the use of the following components during rifle cleaning:
• Cloth patches (sized for the appropriate caliber)
• Brass jag sized properly for your bore [Aluminum and Nylon Jags also work]
• One-piece coated cleaning rod
• General bore cleaner/solvent (Example: Hoppes #9)
• Copper solvent of your choosing (Example: Sweets/KG 12)
• Fitted cleaning rod bore guide
• Plastic AP brush or toothbrush
• Q-Tips
• Plastic dental picks
• CLP or rust preventative type cleaner
There are a number of schools of thought relating to the frequency in which a barrel should be cleaned. At minimum we recommend cleaning a barrel after each shooting session to remove condensation, copper, and carbon build-up. Condensation is the greatest immediate threat, as it can cause the barrel to rust while the rifle sits in storage. Copper and carbon build-up may negatively impact future barrel performance, increasing the possibility of a failure in feed or function. Fouling should be removed whenever possible.
The below tips will help limit the wear of different parts of your barrel during routine maintenance, helping extend the life of the barrel and improving its performance.
The Lands and Grooves
This portion of the barrel may experience reduced efficiency due to copper fouling and cleaning rod damage. If copper fouling takes place during the initial break-in of the rifle, make sure to check our barrel break-in article.
For regular maintenance we suggest using a single piece coated cleaning rod rather than the traditional segmented rod or bore snake. While segmented rods and bore snakes may be convenient for field use, the corners between the segments may bow out and catch on the lands, scraping along the length of the rifling. Residual grit and particles from expended cartridges may also get caught between segments, resulting in an abrasive surface working its way down the length of the barrel. Most bore snakes will remove significant amounts of carbon fouling, but may fall short in the removal residual carbon buildup and copper fouling during deep cleaning. Good rods can be sourced from multiple manufacturers, but we have found good results using both Pro-Shot and Dewey brand products.
General cleaning requires the use of patches rather than nylon or brass bore brushes. Brass brushes may be required when aggressive cleaning is required, but can lead to unnecessary wear on the barrel if used frequently. This is not due to the nature of the soft brushes themselves, but from the abrasive particles of grit that become embedded in the material that is being run repeatedly through the bore. We recommend the use of bore guides when cleaning from both the muzzle and breech. These bore guides will help serve to protect the crown and throat from cleaning rod damage.
If significant resistance develops while running the cleaning rod through the bore, no attempt should be made to force it in further. Back the rod out and inspect the barrel to determine the cause of the resistance. The jag may be pushing between a bore obstruction and the rifling, digging a divot into the barrel before pushing the obstruction back through the muzzle. One way to minimize the risk of a stuck rod is by utilizing a slightly smaller patch during the initial push.
The process of cleaning the length of the rifling is relatively straightforward:
1. Check to make sure the rifle is safely unloaded.
2. Carry out any necessary disassembly procedures prior to cleaning.
3. Remove bolt (if possible) and insert fitted cleaning rod bore guide in action.
4. Soak a patch in bore solvent (similar to Hoppes #9).
5. Center and affix the patch on the brass jag, inserting it into the chamber end of the barrel. A misaligned patch may cause the jag to damage the lands of the rifling, so make sure the patch is centered on the jag. [Note, an aluminum or nylon jag will not show a “false positive”.]
6. Run the patch the full length of the barrel, retracting it upon reaching the end of the muzzle.
7. Let the solvent sit for a minute.
8. Continue to run patches through the bore until carbon residue is minimized.
9. Run a dry patch through the bore to ensure carbon residue has been removed.
10. Soak a patch in copper solvent (Sweet’s or KG-12).
11. Run the patch through the bore, leaving it to sit for 3-5 minutes (do not let solvent sit for more than 15 minutes.*)
12. Repeat this process until no blue residue remains on the patches.
13. Run a patch of Hoppes #9 and a dry patch through the bore to neutralize the copper solvent.
14. Inspect the barrel prior to reassembling the rifle, verifying that no bore obstructions remain.
*Please note that some ammonia-based copper solvents may prove to be corrosive if left sitting in the barrel for an extended period of time. It is essential that these solvents be removed within 15 minutes to avoid ruining the bore.
The Crown
The crown is the portion of the barrel where the bullet loses contact with the lands and grooves and proceeds to exit the firearm. The area most critical to accuracy potential is the angle where the bullet last touches the bore of the barrel.
Avoid damage to this area by using a plastic toothbrush and CLP type cleaner to scrub the crown from the exterior of the barrel. Even the most minimal variation in wear to the crown will negatively impact barrel performance, so be careful to avoid nicking or wearing away this part of the barrel.
Whidden Gunworks makes great sizing and seating dies. The Whidden full-length sizing die with neck bushing is very popular because it allows you to “tune” the neck tension by using different bushings, with larger or smaller inside diameters. In this video, John Whidden explains how to choose a the right bushing size for use with your neck-sizing and full-length sizing bushing dies.
For most applications, John suggest starting with the caliper-measured outside diameter of a loaded cartridge (with your choice of bullet), and then SUBTRACT about three thousandths. For example, if your loaded round mics at .333, then you would want to start with a 0.330 neck bushing. John notes, however, that you may want to experiment with bushings, going down a thousandth and up a thousandth. With thin In addition, as your brass ages and the necks harden, you may want to change your bushing size.
Quick Tip: Try Flipping Your Bushings
You may also want to experiment with “flipping” your neck bushings to alternate the side that first contacts the neck of the case. (One side of the bushing is usually marked with the size, while the other side is unmarked.) So try “number side up” as well as “number side down”.
Some folks believe that one side of the bushing may allow a smoother entry, and that this can enhance concentricity. Other people think they can get very slightly more or less neck tension depending on how the bushing is oriented. This is a subtle effect, but it costs nothing to experiment.
If one bushing orientation proves better you can mark the “up” side with nail polish so that you can always orient the bushing optimally. NOTE: We have confirmed that some bushings are actually made with a slight taper. In addition, bushings may get distorted slightly when the brand name and size is stamped. Therefore there IS a reason to try both orientations.

Splatterburst 1″ circles, 62 per sheet, 10-pk $9.99. These can be pasted on other paper backers.
We’ve all seen conventional splatter targets with a single large black bullseye. When a shot hits the target, a halo (usually neon yellow) appears around the bullet hole. This makes it easier to see your shot placements indoors, or at long range outdoors. Today we feature a variety of other targets that also offer the cool halo/splatter effect. We’ve found grids, multiple bull targets, sheets with 62 one-inch circle pasters, handgun training targets, and even white background splatter targets (that produce black halos). Try out some of these targets for fun (kids love plinking with splatter targets).

Do you own an RCBS electronic powder dispenser? If you do, take the time to watch this ChargeMaster Tuning video from 8541 Tactical. This nine-minute video demonstrates how to re-program your ChargeMaster to “tune” the dispensing process. The video shows the exact programming procedures to follow, step-by-step. Some folks want a faster powder flow — others tune their machines for a more reliable drop (with fewer over-runs). One cheap and popular modification is to insert a 1″-long section of a McDonald’s plastic straw in the ChargeMaster’s silver dispensing tube. This works surprisingly well to smooth kernel drop and prevent “clumping” that can cause an over-charge. The McDonald’s straw MOD is demonstrated in this video, starting at the 6:22 mark.
Large-Diameter Dispensing Tube Mod
Many folks have had success with the McDonald’s straw modification demonstrated in the above video. However, some folks would like to get even better flow performance (with virtually no clumping). Forum Member Frank B. has come up with a new option using a brass hose fitting with a large outside diameter. The hose fitting (with tape wrapped around the barbed nose section) is placed inside the RCBS dispensing tube (have some kind of wrap — you don’t want metal-on-metal). Here’s how the unit looks installed:
Frank tells us: “I have found a cure for the over-throw problem. It is a simple 1/4″ barbed hose nipple. I wrapped a couple layers of tape around the barbed end for a snug fit. With this in place, I have thrown 100+ charges of Varget without a single overthrow. The ID of the barbed end needs to be approximately 3/16″ to feed a steady flow. This works because of the larger ID at the drop.”
Frank adds: “You can see in the photo that the powder is not stacking up. You can watch it drop one grain at a time. Hope this will take the aggravation out of your case charging.” For best performance with this brass fitting MOD, we recommend de-burring and smoothing out the front edge of the brass fitting over which the kernels drop.

Remington Ammunition Plant Re-Opened by Vista Outdoors
This video shows ammo production at the re-opened Remington ammunition plant in Lonoke, Arkansas. “This is one of the largest ammunition manufacturing plants in the world” said Mark Keefe, NRA Publications editorial director. “It was set up in 1969 by DuPont, who owned Remington at the time. They do it all here. Cases, bullets, centerfire rifle, centerfire pistol, rimfire and shotshell.” It’s great to see this plant back in production after Remington Ammunition filed for bankruptcy in 2020 and the assets of the Remington conglomerate were auctioned off. Ultimately, Vista Outdoor, owner of Federal, CCI and Speer, purchased the assets of Remington Ammunition and got the Lonoke plant running again, better than ever.

Do you know how gun primers are made — how the explosive elements are applied into those tiny cups? Find out by watching this video filmed at a Federal ammunition factory. It starts out with empty primer cups loaded, 1000 at a time, into trays using vibration (0:05 time-mark). While much of the process is automated, there is still a significant role played by production workers who apply a green, paste-like charging compound to the inside of hundreds of primer cups.
At the 0:17-second time-mark you can see the factory worker “charging” the primers with the priming compound. After the cups are filled, then the plate of cups “mates up with a plate of anvils” (0:40 time-mark). Then the primers are unloaded from trays and inspected.
Primer “Mysteries and Misconceptions” Article
There is an excellent article about primers on the Shooting Times website. This authoritative Shooting Times article explains the fine points of primer design and construction. The author reveals some little-known facts about primers and corrects common misconceptions. Here are some highlights:
Size Matters
Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.
Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.
Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.
We really like rimfire revolvers here at AccurateShooter.com. A good .22 LR wheelgun will be fun, accurate, reliable, and inexpensive to shoot. Rimfire revolvers also offer much less recoil and noise than a centerfire pistol. Your Editor has owned a Smith & Wesson Model 617 for over 20 years. That old S&W has probably fired more rounds than all the other handguns I own, combined — yet it still runs flawlessly and still delivers excellent accuracy.
Ruger offers a big stainless .22 LR wheelgun to compete with the S&W Model 617. This rimfire wheelgun is based on Ruger’s trusted GP100 platform. The Ruger GP100® chambered in .22 LR looks to be a good firearm — strong, versatile, and intelligently engineered. In the video above, the late Jeff Quinn of Gunblast.com tests the Ruger revolver and gives it high marks: “It’s a good hefty gun [42.6 oz.], but not overly large or heavy for a good trail gun. It’s just a really nice, well-made revolver from Sturm Ruger.” The gun Jeff tested had a 3.7-lb SA trigger pull and a 9.8-lb DA pull.
The .22 LR GP100 features a windage and elevation adjustable rear sight with a white outline, a light-gathering fiber optic front sight and the original full-size GP100 rubber grips with hardwood inserts. With all stainless-steel construction, the rimfire GP100 is easy to maintain. Just keep the cylinder chambers and barrel clean and this gun should run forever.
This Review of the .22 LR GP100 by Hickok45 has over 6.9 Million Views:
The 10-shot Ruger GP100 in .22 LR is a durable, well-engineered wheelgun. Ruger’s engineers optimized the GP100’s innards to deliver a smooth double-action pull: “The new GP100 has an improved fire-control system that uses a lighter mainspring than previous Ruger double-action .22 LR revolvers … we’ve done a lot of development on the firing pin location and geometries so that we’re able to put a lighter trigger pull in this gun than you would find in other .22 LR [handguns]. We’ve got a half-underlug barrel, and it’s a smaller diameter so the gun balances real well. We’ve added a narrow-spur hammer and a smooth trigger.”

More and more shooters are “wet-tumbling” their brass (in liquid) with reusable polishing media, rather than using dry media in a vibratory tumbler. The “wet-cleaning” method works best with a rotary tumbler fitted with a water-tight, horizontal drum to hold your brass, cleaning solution, and stainless, pin-type media. The rotary tumbler of choice has been the Thumler’s Tumbler Model B Heavy-Duty. That is a great, sturdy machine, but now you have a more affordable option.
Frankford Arsenal offers “Platinum Series” rotary tumblers designed to clean cartridge brass with liquid and stainless media. The watertight, polymer drum rides on four rollers which rotate the drum around its horizontal axis. Two filters are provided so you can quickly separate your brass and media. A built-in timer allows you to set tumbling sessions up to three hours. There is a large, 7-liter unit and a smaller, 3.3-liter tumbler. Frankford Arsenal says the big version will clean up to 1000 cases of .223 Rem brass. That’s impressive capacity.
Rotary Tumbler Sources Online
The Frankford Arsenal Platinum Series rotary tumblers are sold by major retailers including Grafs.com, Midsouth, MidwayUSA, and Amazon. It’s wise to shop multiple vendors to find the best current pricing.
Amazon often has very competitive pricing on the Frankford Arsenal Rotary Tumblers, both the big, high-capacity 7-liter unit ($179.97) and the smaller 3.3-liter tumbler ($84.99).
How to Wet-Clean Your Brass in a Rotary Tumbler On our main Accurateshooter.com website, you’ll find a comprehensive review of the STM system for cleaning cartridge brass with stainless media. To clean brass with stainless media, start with five pounds of small stainless pins sold by StainlessTumblingMedia.com. Place these along with a gallon of water, a little liquid cleaner, and two pounds of cartridge brass in a rotary tumbler, and run the machine for one to four hours. After cleaning be sure to inspect all your primer holes. CLICK HERE for Brass Cleaning System Review.
Forum Member Tests STM System
Our reviewer, Forum member Jason Koplin, purchased the STM media and a new Thumler’s Tumbler. He then tested the STM cleaning procedure on his own brass, including some extremely dirty and tarnished “range pick-up” brass. Jason was thoroughly impressed with how well the STM process worked — as you can see from the “before and after” photos below. Brass which looked like it was ready for the scrap heap was restored to “like-new” appearance. The process works equally well on both rifle brass and pistol brass. Jason observed that one surprise benefit of the STM cleaning procedure is a big reduction in noise. Jason said the water-filled rotary tumbler was much quieter than his vibratory tumblers. One tip though — you should always inspect every cartridge carefully after wet-tumbling with stainless media. With large-flash-hole brass it is possible to have a pin stuck in a flash hole. This is rare, but it CAN happen.

33XC — Popular ELR Cartridge
Paul Phillips is a past King of 2 Miles (K02M) winner. The founder of the Global Precision Group, Paul is one of the top ELR marksmen on the planet. He has also been a team-mate of past K02M winners.
In 2019, Paul had this rifle built for the 25-lb max, .338 caliber-or-under ELR Class. This is chambered for the 33XC, an efficient cartridge devised by 11-time National HP Champion David Tubb. With promising initial testing at 500 yards, it looks like Paul’s 33XC project is a success. The rifle’s first match was the NRA Extreme Long Range Championship held in 2019 at Camp Atterbury, Indiana.
Paul reports: “The 33XC is ready… I have tested loads from 3100-3450 FPS and and will settle on a load around 3250 FPS [which is] my most accurate load so far. The Peterson Cartridge brass is really working well.”
Paul states he would like to look for a higher node from 3300-3400 GPS: “Next stop is with the Applied Ballistics LLC mobile labratory and radar testing with a PDM.” Paul cautions: “I encourage everyone to start low and work up. Every chamber, barrel, and components are a little different.”
During initial testing, Paul’s 33XC put three shots in 0.27″ at 100. Then, at 500 yards, the rifle produced a 3-shot group around 1/3-MOA with just 1.22 inches of vertical. That’s pretty impressive for early testing. Paul will also be trying some Berger bullets soon. When he determines the most accurate load, Phillips will stretch the rifle’s legs, shooting out to 2500 yards and beyond.
Quote: “The Cutting Edge Bullets are not the highest BC but they are very stable and consistent at ELR (sub-sonic) ranges and that’s the most important factor in finding the best ELR bullet. I actually test all my bullets at sub-sonic speeds to make sure they are consistent and stable. Finding a good load at 500 yards is just the first part. The real test is shooting them at sub-sonic speeds and see how consistently they group. This is what gives you the highest percentage to impact at 2 miles and beyond.”
This rifle features a BAT action mated to a 34″ Bartlein barrel chambered for David Tubb’s new 33XC cartridge. Paul Phillips is currently running Cutting Edge 275gr Lazer solid bullets. Paul notes: “I also have a .338 Lapua Magnum barrel and 300gr Berger bullets for the restricted class in France.” Paul gave special thanks to Alex Wheeler for doing the metal work and Alex Sitman for doing the bedding.
Rifle Component List
Action: BAT Machine CTH dual-port action
Trigger: Bullet Central Bix’N Andy
Barrel: Bartlein 1:8″-twist barrel (34″)
Chambering: 33XC for Peterson brass
Stock: McMillan A6 Super Mag, Bedding Alex Sitman
Scope: Nightforce Optics 7-35x56mm F1 ATACR.
Bipod: Duplin Rifles
Paul Phillips notes: “Alex Sitman has been bedding rifles stocks for most of his life. I believe that [bedding] is a very important … to keep consistent accuracy and repeatable zeros after traveling all over the globe.”
Even with the TacomHQ Charlie Tarac scope prism in place, the rifle makes the 25-pound weight limit with Duplin Rifles bipod. Paul says: “I love it when a plan comes together!! I’m under by 2 ounces!”
About the 33XC (eXtra Capacity) Cartridge
David Tubb invented the 33XC cartridge because he thought the CheyTac cases were too much trouble — requiring a larger action, oversize presses, and ultra-expensive dies. The 33XC was designed to fit .338 Lapua Magnum-size actions and use normal reloading presses.
The 33XC (eXtra Capacity) has 137.5 grains of H2O capacity with over 125 grains of usable powder capacity while leaving the 0.393″ neck unfilled for bullet seating.
The 33XC has a .338 Lapua Magnum lineage. Think of it as a better, 35°-shoulder .338 LM. David explains: “The 33XC uses standard reloading dies along with a 7/8″ x 14 TPI reloading press. There is no fire-forming — all case ‘improving’ has already been done with a production case that has 20 grains more powder capacity, 35-degree shoulder, and longer neck compared to a .338 Lapua Magnum. This puts the various .338 Lapua wildcats and the Rem Ultra Mag Improved into the ‘also ran’ category. They simply can’t compete with the velocities attainable with the 33XC.”
The 33XC is based off of a .580″ bolt head. Tubb states that “A fired case will extract with little effort when using a properly-polished chamber with a maximum powder charge after resizing with the Superior Shooting Systems FL sizing die.” Tubb’s 33XC die reaches the case head which is important for accuracy. Peterson Cartridge produces the 33XC brass for Superior Shooting Systems. This high-quality brass costs $260 for 100 cases (i.e. $2.60 per case), and can be purchased directly from Superior Shooting Systems.
Bonus Video — Global Precision Group Team Makes 4-Mile Hit
With a .416 Barrett rifle, Team GPG makes a 4-mile impact that is captured on video during team practice. James Devoglaer was shooting his GPG spec .416 Barrett with Team Captain Paul Phillips doing the ballistics and wind. Spotters were David Parrish and Derek Rodgers. Forward Observers were John Droelle and Mauro Del Mastro. Approximately 60 shots were taken before impact. There were four 3-shot groups that measured under 2 MOA at 4 miles. The .416 Barrett cartridges were loaded with 550gr Cutting Edge bullets and Vihtavuori powder.
If you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.
Lyman’s sturdy Victory Single-stage Press is a full-size unit that competes with the RCBS Rock Chucker Press. With beefy cast iron construction, the Victory’s strength and leverage rivals the Rock Chucker. The press operates smoothly and the handle can be mounted on either side.
Nearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.
The Lee Classic Cast Breech Lock Press offers excellent value for the money ($190.99 at Midsouth). Based on the proven design of the Classic Cast press, the updated Breech Lock series adds the quick-change die bushing and an improved primer drop system. This press is strong, with cast iron frame, all-steel linkage, and 12 square inches of ram bearing surface.
