Saturday Movies: Six Notable Ultimate Reloader Video Reviews

Ultimate reloader gavin gear longshot camera AMP press anschutz rifle 7mm PRC 6.5 PRC 300 muzzle brake videos

UltimateReloader.com offers some of the most thorough firearms and reloading tool tests on the internet. And UltimateReloader’s YouTube Channel has hundreds of great videos that showcase reloading tools, accurate firearms, precision optics, gunsmithing methods, and top-tier reloading components. For today’s Saturday at the Movies feature, we showcase six great videos recently created by Gavin Gear and his UltimateReloader team. These videos highlight a superb Long-Range Target Camera, the remarkable AMP Press, the new Hornady PRC cartridges, and other interesting topics. On this final day of 2022, enjoy our Saturday Video Showcase.

With the high price of centerfire powders, bullets, and brass, everyone should have an accurate .22 LR rimfire rifle for marksmanship training and competition at 25 to 200 yards. In this video, Ultimate Reloader’s Gavin Gear tests the impressive Anschutz 54.18 BR50-U7 match rifle using a quality Sinclair Int’l front rest. Anschutz offers several versions of the 54.18 and BR-50. There are two barreled actions available: 20″ threaded and 25.9″ non-threaded. Gavin tested the 20″ threaded model with the U7 stock. In this video, Gavin tested the trigger with a sophisticated TriggerScan TS-11. The trigger was superbly repeatable at a measured 3.8 ounces. Gavin also did a bore examination. He then tested the Anschutz with a variety of premium ammo. In this rifle, Lapua Midas+ producing the smallest groups. FULL STORY HERE.

This video features the impressive, high-tech AMP Bullet Seating Press. The AMP Press combines a motor driven ram, a distance sensor, and a load cell to deliver extremely accurate and precise force/distance bullet seating measurements. The AMP Press offers unrivaled consistency in the bullet seating process. And as the AMP Press is linked to a computer, seating data can be stored and you can chart variations in seating resistance. A wealth of precise data is collected during the bullet seating process. This helps you optimize your brass prep and annealing for the best, most consistent results. FULL STORY HERE.

Past 400 yards or so, it can be difficult to see bullet holes on paper, even with spotting scopes. That’s why we recommend a high-quality wireless target camera. The best long-range target cameras on the market are produced by Longshot Camera Systems. The Longshot Target Cam provides a live WiFi camera feed. This comes back to your shooting station and you can view the image with a laptop or mobile device. You don’t need internet coverage and no separate tall antennas are required. Simply place the camera unit next to your target and the receiver unit close to your rifle or bench. The Longshot system is completely self-contained. Longshot produces a variety of cameras starting at $449.00 for the LongShot Marksman. We recommend the $899.00 LR-3 unit which works out to two miles! In this video Gavin Gear of UltimateReloader tests the LR-3 at long range. PRODUCT INFO HERE.

This video examines how muzzle brakes reduce recoil. Just how important is bore clearance for a muzzle brake? Should you have an exit diameter that’s just slightly larger than bullet diameter, or will a larger diameter work well also? Along with no brake at all (bare muzzle), Ultimate Reloader tested multiple different brake bore clearances on a 6.5 Creedmoor rifle: 0.010″ over bullet diameter, 0.020″, 0.030″, 0.050″, 0.100″, and 0.200″. The testers expected to get the best recoil reduction with the tightest fit. Surprisingly, this wasn’t quite the case.

Ultimate reloader gavin gear muzzle brake bore clearance video

Using all brake configurations (all bore clearances) Ultimate Reloader saw a significant reduction in recoil, almost half, as compared to a bare muzzle: “What we didn’t expect was how close together the rest of the clearances would cluster. All of the clearances that we tested had good recoil reduction.” FULL STORY HERE.

Dillon Precision continues to be the leader among progressive press makers. Dillon offers the largest variety of progressives, the most accessories, and legendary customer service. In this video, Gavin Gear of Ultimate Reloader looks at a variety of Dillon machines to help buyers decide which progressive best suits their needs. Featured Dillon progressives include: Square Deal B, Xl750, and RL1100. Along with basic press feature, Gavin shows the operation of Dillon’s automated bullet feeder and case feeder accessories. The video also provides pricing summaries with various configurations. FULL STORY HERE.

Hornady’s PRC (Precision Rifle Cartridge) family of cartridges are becoming quite popular. The 6.5 PRC fits in a short action, while the 7mm PRC and 300 PRC both require a long action. The 7mm PRC is a long-action centerfire hunting cartridge designed to shoot 180gr bullets at 2950+ FPS. The 6.5 PRC is a good hunting cartridge that can fit a standard-length action. And, a number of top F-Open shooters are necking up the 6.5 PRC for 7mm bullets. This 7-6.5 PRC wildcat has shown excellent F-Class accuracy with a higher velocity node than the .284 Winchester. Along with these two cartridges, Hornady has a 300 PRC that can shoot the big .308-caliber bullets. In this video, Ultimate Reloader analyzes and compares each of the three PRC cartridge types.

Saturday Movies: Priming Tools and Techniques Videos

video primer priming seater tool video review primal rcbs lee hand bench

Seating primers is a key part of the reloading process. You need to seat primers consistently to achieve best accuracy. There are many different tools offered for seating primers, both hand-held and bench-mounted. Deluxe premium hand-held seaters may hold just a single primer, while a variety of handheld units employ trays to hold more primers. With bench-mounted primer seaters there are a variety of feeding systems — vertical tubes, angled trays, and even a strip feeder — the APS system pioneered by RCBS.

Today’s Saturday at the Movies feature covers a variety of primer seater options, from low-cost hand tools to the $600.00 Primal Rights unit. We also cover the innovative Lee Automated Case Primer (ACP) system which even feeds your brass, increasing your processing rate.

Forster Co-Ax Bench-Mounted Priming Tool

The Forster Co-Ax® Primer Seater is a trusted bench-mounted priming tool that works very well. Set the jaws for a particular rim size, load the tube, and you’re ready to seat primers. The tool has good “feel” plus plenty of leverage. Forster says that the tool’s “unique design allows the operator to eliminate all slop when working with a specific cartridge, translating into perfect seating, reliable ignition, and reduced misfires.” This Forster tool requires no separate shell holders. The spring-loaded jaws close to securely grip most modern rifle and pistol cases with a rim thickness of .045″ to .072″. And Forster provides a primer flipper tray that makes it easy to load the provided small and large tubes. If you shoot a large variety of cartridge types with various rim sizes, this Forster Co-Ax primer seater is a good choice.

Primal Rights Competition Priming Seater (CPS) Review

If there is a Ferrari of priming tools, it has to be the Primal Rights Competition Primer Seater (CPS). This impressive bench-mounted tool allows very precise control over primer seating depth. A vertical tube holds primers ready for insertion. The action is smooth and precise. Seating depth control is as good as you can get. That precise, repeatable control, and the tool’s smooth operation, are the tool’s major selling points. Video reviewer F-Class John believes that Primal Rights machine is definitely the best priming tool on the market, though it may not be for everyone given its premium $600.00 price.

Frankford Arsenal Perfect Priming Tool

Our friend Jim See of Elite Accuracy LLC has tested the depth-adjustable hand priming tool from Frankford Arsenal. This product, called the Platinum Series Perfect Seat Hand Primer, has some unique features. Primer seating depth can be adjusted with a handy wheel in the tool’s center handgrip. Each “click” of the wheel moves the primer post .001″ (one one-thousandth of an inch). Additionally, the design of the case-holder allows quick and easy removal of a primed case. The unit ships with a full set of shell-holders to match all types of cases. Like many other hand priming units, the primers are loaded into a flip tray that attaches to the head of the tool.

Frankford Arsenal Perfect Priming Tool jim see review

Accuracy Variances and Priming Tool Types

The above video compares the performance of the Frankford Arsensal adjustable priming tool with a Sinclair Int’l hand priming tool — a unit used for many years by top benchrest shooters.

LEE Auto Bench Priming Tool

Gavin Gear of UltimateReloader.com has reviewed Lee Precision’s new lever-operated, bench-mounted priming tool. The Lee Auto Bench Prime features a hopper-style primer feeder set at an angle. Gavin likes the tool, reporting that primers feed well and seat fully with very little effort. And switching from large to small primer size (or vice-versa) is quick and easy. Overall, Gavin says the Lee Auto Bench Prime has earned a place in his reloading room: “The Lee Auto Bench Prime is easier to use than a hand priming tool, and more efficient.”

How the Lee Auto Bench Prime Performs
Gavin had three important “take-aways” from his initial loading sessions with the Lee Auto Bench Prime:

1. I was surprised by the low effort needed to prime cases — it’s pretty amazing.
2. You can quickly and easily install shellholders and change primer sizes.
3. The folding primer tray works very well. It’s a great setup from my testing so far.

Are there any negatives with the tool? Gavin noted that, in the course of loading 100+ rounds, once or twice he had to tap the triangular tray to get the primer to feed: “That’s not a big deal, and may smooth out with time”.

RCBS APS Strip Priming System — Bench Tool and Strip Loader

rcbs aps strip priming system hand toolRCBS pioneered an innovative priming system that held primers in handy horizontal strips. This video shows primers being placed in strips, and then cases being primed using an RCBS bench-mounted APS strip-priming system. Many years ago, this Editor acquired an RCBS Pro 2000 progressive press, which employed the APS strip priming system. Primers were held in strips which could be easily connected for continuous feeding — no tubes to load! I liked the system so much I then acquired an APS hand priming tool (photo right), an APS bench-mounted tool, and an APS strip priming tool that fits on a single stage press. I loaded many thousands of rounds successfully with the APS system with not one inverted primer ever. I still use the APS hand primer tool to prime most of my rifle rounds.

video primer priming seater tool video review primal rcbs lee hand bench

Unfortunately, RCBS has discontinued sales of most APS priming tools, but you can still get primers pre-packaged in APS strips, and you can still buy the Strip Loader tool for placing primers into strips.

BONUS Video — K&M Primer Pocket Correction Tool

K&M offers a handy tool for optimizing primer pocket depth. K&M’s Primer Pocket Correction Tool uses a carbide cutter with a preset depth, allowing consistent depth squaring of the primer pocket bottom. Designed with a drive shank to be used with your cordless screwdriver and/or a K&M handle, these tools are available in four types: Small Rifle/Pistol; Large Pistol; Large Rifle; and .50 BMG.

Priming Tool Tip — Check Your Primer Seater for Wear

Priming Tool APS CCI magnum Primers Lee RCBS Priming

From time to time, we all encounter a primer that doesn’t go off. It’s normal to attribute the problem to a bad primer. But sometimes there are other explanations. George S., one of our Forum members, experienced a couple failures to fire, but he learned that the issue was his priming TOOL, not his primers. Here’s what George told us. There’s a lesson to be learned:

“I had issues with CCI 450s when I had my first 6BR barreled. I had probably three or four out of 20 rounds that failed to fire. the primers were dented but didn’t fire. I called CCI since I had bought a case of them. The tech was decent enough but had the audacity to tell me I was not seating the primers all the way in the pocket. I proceeded to let him know I had been reloading longer than he had been alive and I knew how to seat a primer.

Turns out that I did and I didn’t! I was using the RCBS primer tool I had used for years and the primers felt just fine to me. I finally decided to check the tool and since I had a new one I took the seating pins out and measured them. The seating pin on the tool I had been using for years was shorter by a few thousandths! I then used the pin from the new primer tool and darned if the primers that didn’t seat down to the bottom of the cup.

Saturday Movies: Progressive Press Five Brand Showcase

ultimate reloading progressive press review dillon Mark 7 rcbs lee hornady

If you shoot high quantities of ammunition in pistol or rifle competition, you should consider acquiring a good progressive press. Because multiple operations (sizing, powder dropping, bullet seating etc.) take place with a single pull of a lever, a progressive press can produce way more ammo in a given period of time than any single stage press. With a progressive, on the ram up-stroke, the multiple stations can simultaneously remove spent primer, full-length size case, drop powder, seat bullet, and crimp (if desired). Most progressives are also set up to prime cases with the ram in the lower position — though some guys prefer to prime manually.

Progressive presses aren’t just for high-output pistol ammo or bulk rifle ammunition. Good progressives can be adapted to do certain reloading tasks for top-on-the line match ammo. You might use a progressive for decapping, priming, and sizing, then throw powder and/or seat bullets separately. Some Champion shooters do use progressives to load their match ammo! For example 5-Time National Long Range Champion John Whidden and 2020 Berger SWN F-Open Champion Jay Christopherson both use progessive presses for some (but not all) operations.

To help you get started with progressive presses, here are six videos from UltimateReloader.com that cover seven popular machines, from the elite Mark 7 Evolution to the affordable Lee Loadmaster. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency. Machines Covered: Lyman Mark 7, Dillon XL-650, Dillon XL-750, Dillon RL-550c, RCBS Pro Chucker 7, Hornady Lock-N-Load AP, and Lee Load Master.

SAFETY BONUS — Why You Need a Lock-Out Die


The RCBS Lock-Out Die can also be used with some Dillon and Hornady progressive presses.

If you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works.

The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.

RCBS Lock-out die RCBS Lock-out die

It takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.

While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). This Editor has used the RCBS Lock-out die very successfully on an RCBS 2000 progressive press for many years.

Saturday Movies: Power and Manual Case Trimmers in Review

powder manual case trimming cartridge length trimming henderson wilson lyman giraud gavin gear erik cortina ultimate reloader

A good case trimmer is an essential tool for precision hand-loading. To ensure consistent loads, you want your cases to be the exact same length. Today’s Saturday Showcase features five trimming tools, both powered and manually operated, that can trim your sized brass with great precision. In addition, some of these tools will also chamfer case necks inside and out. The powered case trimmers will save you considerable time (and effort) when working will large batches of brass.

Lead photo shows the Henderson Gen 2 trimmer from Panhandle Precision video review.

Henderson Gen 3 Power Trimmer — Ultimate Reloader Review

Gavin Gear of UltimateReloader.com has tested the impressive Henderson Gen 3 (V3) Trimmer. You’ll find a full write-up on Gavin’s website, and you can watch Gavin’s 18.7-minute video review above.

Gavin states: “The Henderson Gen 3 case trimmer is built on an adjustable tri-trim 3-way cutter with different pilots to accommodate different case necks. Three-way cutters trim to length and chamfer the inside and outside all at once. This trimmer has a 1700 RPM spindle and a custom DC motor made in the USA. The Henderson trimmer works much like a milling machine. You do not need much torque because of the way the taper works. The Henderson Gen 3 trimmer delivered outstanding cartridge length consistency after trimming. This trimmer is fast and easy to use and most importantly, returns consistent results.”

CLICK HERE for Henderson Gen 2 Trimmer video review, which shows how to how to set trim length and change cutter heads, using 6.5×47 Lapua, .260 Remington, and .300 Winchester Magnum cases.

Giraud Power Case Trimmer — Full Review by Erik Cortina

In this video, Erik Cortina of CortinaPrecision.com offers some very clever and useful tips that will help you get the most from your Giraud powered case trimmer. The Giraud trimmer is very precise. When set up correctly, it can trim brass with amazing consistency.

Erik Cortina power case trimmer Giraud

In the video, Erik trims 5 pieces of brass in 15 seconds (6:32 mark). He then measures all five with precision calipers (7:00-8:08). All lengths are exact within .0005 (half a thousandth). Erik notes that the Giraud trimmer indexes off the case shoulder. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.

Lyman Powered Case Trimmer Review

The Lyman Case Trim Xpress is an efficient, precise unit that allows easy adjustment of trim length with a click-adjustable collar. The trimmer comes with a set of cartridge-specific bushings that index off the case shoulder. One nice feature is a variable speed control. For the price, $146.20 on Amazon, this trimmer delivers excellent performance. To see more details, check out F-Class John’s video review of the Lyman Case Trim Xpress which shows set-up and operation.

Frankford Arsenal Universal Case Trimmer (for Power Drills)

This video features a handy tool that attaches to a portable drill. Used with various diameter collets, this can trim most popular sizes of shouldered brass. The universal collet system indexes on case shoulders for precise and consistent trimming (this does NOT work with straight-walled cartridges). The built-in depth micrometer allows for quick and precise micro-adjustments. There is a handy brass shaving ejection port. The system works well, particularly if you can stabilize your power drill in one position. This Frankford Arsenal trimmer, under $65.00 on Amazon, is an affordable alternative to the top-end powered case trimmers. It comes with a handy plastic case that holds the trimmer and collets.

L.E. Wilson Manual Case Trimmer

L.E. Wilson, makers of hand dies, case trimmers and other precision reloading tools, makes a popular and precise stainless steel case trimmer with micrometer adjustment. The above video explains the operation of the Wilson trimmer and shows how to trim cases and use the micrometer case length control positioned opposite the hand crank. We definitely like the micrometer control. This feature allows you to set the cartridge overall trim length with great precision. If you are trimming a variety of different cartridge types, the micrometer cut length control comes in very handy.

If you own a L.E. Wilson case trimmer, you should watch the official Accessories Video from L.E. Wilson. This video shows accessories for the L.E. Wilson trimmer. These include: Power Adapter for trimming (replaces hand crank), Titanium Case Trimmer Cutter (longer life), Inside Case Neck Reamer, Primer Pocket Reamer (removes military crimps), Uniform De-Burring Tool, Neck Chamfer Tool (30° and 45°), and handheld inside/outside deburring tool (and power adapter).

BONUS Video: How Important is Consistent Case Length?

This Primal Rights video explains why it is important to maintain precise case lengths if you want best accuracy and most consistent ES/SD. You’ll want to size your cases BEFORE trimming if your trimmer indexes off the case shoulders.

.223 Rem vs. 5.56x45mm NATO — Key Facts You Need to Know

.223 Rem Remington 5.56 SAAMI CIP 5.56x45 5.56x45mm NATO cartridge ammo pressure test luckygunner ultimatereloader Gavin Gear

Probably the most popular centerfire rifle round in the Western Hemisphere is the .223 Remington and its metric match, the 5.56x45mm. Though many folks use “.223 Rem” and “5.56×45″ interchangeably, there are some meaningful differences in specifications for the original .223 Rem and the 5.56x45mm cartridge, as adopted by the U.S. military and NATO armies. The default chamber throats are slightly different and the .223 Rem is rated at 55,000 PSI vs. 62,366 PSI for the 5.56x45mm.*

.223 Rem vs 5.56x45mm — Key Differences
There is a truly outstanding, very thorough article on the subject, published by LuckyGunner.com.** This involved extensive testing, with pressure monitors, of 5.56x45mm ammo in .223 Rem chambers. Those tests revealed the peak pressures. Here is one of the ammo test charts:

.223 Rem Remington 5.56 SAAMI CIP 5.56x45 5.56x45mm NATO cartridge ammo pressure test luckygunner ultimatereloader Gavin Gear

NOTE: “The observed chamber pressure for Federal XM855 5.56mm ammunition in a .223 Rem chamber exceeded .223 maximum pressures, but not by a massive amount. The ninth shot (the red line) was an underpowered cartridge which exhibited significantly lower velocity and pressure than the other rounds, so it was excluded from the average velocity and pressure numbers for this chamber.”

And if you’re curious, LuckyGunner also fired .223 Rem ammo in a 5.56x45mm NATO-chambered AR15 rifle. As you would expect, the peak pressures were significantly lower, but the .223 Rem ammo still cycled the semi-auto AR-platform rifle perfectly well:

READ FULL LuckyGunner .223 Rem vs. 5.56x45mm ARTICLE »

UltimateReloader.com Explains .223 Rem vs. 5.56x45mm
To explain the key differences between the .223 Rem and 5.56x45mm cartridges our friend Gavin Gear of UltimateReloader.com has created a very thorough 12-minute video. This covers the cartridge specifications and explains key considerations for hand-loaders. Gavin also addresses the oft-asked question “Can I shoot 5.56x45mm ammo in my .223 Rem chamber?” Gavin’s video is definitely worth watching. In fact, this is one of the most popular videos Gavin has ever created — it has been watched nearly 4.5 million times on YouTube.

What Exactly Is the 5.56x45mm NATO Cartridge?
The 5.56×45mm NATO is a rimless bottle-necked intermediate cartridge family standardized by NATO with development work by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.

Bullet diameter: 5.70 mm (0.224 in)
Maximum pressure (EPVAT): 430.00 MPa (62,366 psi)
Maximum pressure (SCATP 5.56): 380.00 MPa (55,114 psi)
Case length: 44.70 mm (1.760 in)
Rifling twist: 178 mm or 229 mm (1 in 7 in)
Parent case: .223 Remington (M193)

Ammo-Maker Federal Premium Compares .223 Rem and 5.56x45mm
Here is a video from ammo-maker Federal Premium explaining the difference between .223 Remington and 5.56x45mm NATO. Federal states that you may experience excessive pressures when firing a 5.56x45mm in a standard .223 Remington chamber:

One leading gunwriter has addressed the question of shooting 5.56x45mm ammo in .223 Rem chambers. He advocates caution (for more info, SEE pressure tests by LuckyGunner.com):

“I have received a slew of questions — many from first time AR-type rifle buyers — about the .223 Rem and the 5.56×45 mm NATO cartridges. Can I shoot 5.56×45 mm NATO in my .223 and vice-versa? Are these the same cartridge?

Externally, the two cartridge cases are identical. The main differences are that 5.56×45 mm NATO operates at a higher chamber pressure (about 60,000 PSI versus 55,000 PSI on the .223 Rem.) and the 5.56’s chamber is slightly larger than that of the .223 Rem. Also, the throat or leade is longer in the 5.56×45 mm chamber. What does this mean? You should not shoot 5.56×45 mm NATO out of a rifle that is chambered in .223 Rem [with a standard short throat]. And be aware that some .223 Rem ammunition will not reliably cycle through some AR-style .223 Rem rifles, but it usually does. As a matter of fact, I have not encountered any difficulty with current .223 Rem. loads cycling through a 5.56 mm AR-style rifle.” — Mark Keefe, Editor, American Rifleman


* According to the official NATO proofing guidelines, the 5.56×45mm NATO case can handle up to 430.0 MPa (62,366 psi) piezo service pressure. The U.S. SAAMI lists Maximum Average Pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa). The chamber for military 5.56×45mm NATO has a longer throat prior to the bullet contacting the rifling which results in lower pressures when firing 5.56×45mm NATO ammunition. If 5.56×45mm NATO is used in rifles chambered for .223 Remington the bullet will be engraving the rifling when chambered. which can increase pressures past SAAMI Max levels. NOTE: The C.I.P. standards for the C.I.P. civilian .223 Remington chamber are much closer to the military 5.56×45mm NATO chamber.

** The full-length LuckyGunner article is well worth reading. It even provides specifications for a number of .223 Rem reamer types, and compares the original .223 Rem, the 5.56x45mm NATO, and the modern .223 Wylde chamberings.

MEC Marksman — Impressive Single-Stage Press Reviewed

MEC Marksman reloading press single stage Rock Chucker RCBS cast-iron

MEC Marksman reloading press single stage Rock Chucker RCBS cast-ironIf you need a heavy-duty, single-stage reloading press, definitely look at the MEC Marksman, a beefy black single-stage unit with many impressive features. MEC, noted for its shotshell reloading machines, now offers the cast-iron MEC Marksman press, offering many features we really like. First, the rugged, cast-iron frame is strong enough for the toughest reloading jobs. Second, the Marksman features an OPEN front — that smart design makes it easier to insert and remove cartridge cases. It also makes it much easier to place your bullets during the seating stage.

This open-front design makes good sense — note that Hornady’s LNL single-stage press also has an open-front layout. Importantly, the MEC Marksman has an innovative, self-centering shell-holder. This patented design should help hand-loaders reload more efficiently.

MEC Marksman Press USER MANUAL »

We are impressed with the MEC Marksman press. The Marksman combines a sturdy cast-iron frame with a smart, user-friendly open-front design. The Marksman ($257.54 at MidwayUSA) costs $30 more than an RCBS Rock Chucker ($227.61 at MidwayUSA). However the MEC Marksman offers some distinct advantages — such as the open front plus the patented floating shell-holder system.

MEC Marksman Press Review by Ultimate Reloader

UltimateReloader’s Gavin Gear 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.”

Gavin liked the Marksman’s system for holding spent primers. A tray sits behind the ram to catch spent primers exiting from a hole near the bottom of the ram. This is more foolproof than the plastic primer cups on some other single-stage presses. Expect less spent primer “spillage”.

The Marksman is sold as a stand-alone unit. However MEC also offers a very nice steel mount/riser for the Marksman. Gavin tested the Marksman with this riser, and he says it was sturdy and well-built. Gavin liked the riser. He said that elevating the Markman press up above the benchtop made it easier to handle cases and to operate the handle. You also get extra left- and right-side die-holders.

Area 419’s Impressive 9-Station ZERO Turret Press — Full Review

Area 419 Zero reloading turret 10 station reloading press ultimatereloader review gavin gear

Area 419 offers the impressive ZERO reloading press, a 9-station turret press with some very unique features. This press was designed to be the most precise turret ever created. As tested by Gavin Gear of UltimateReloader.com, the ZERO turret press delivered very impressive shoulder-bump consistency and ultra-low seated bullet run-out (about +/- 0.0005″). The numbers were as good as you can get from a quality single-stage press, so Area 419 did some impressive engineering. We would expect that, as this is an expensive product — MSRP is $1275.00. SEE FULL REVIEW on UltimateReloader.com.

The ZERO turret press lets you install up to nine (9) different reloading dies in the large top turret, which revolves around a central axis. But unlike most turret presses, the ZERO doesn’t have flex or wobble when you’re loading. This is because Area 419 includes a clever system for locking the turret in position after you’ve selected the die from your array. Area 419 also uses a unique system for securing shell-holders (see video at 12:00). This, likewise, adds to the precision of the press.

In the video above, you can see how the turret is secured with a “wedge clamp”. By loosening the wedge clamp you can index the press easily to any station. Then, when you have selected your die, you tighten the wedge clamp again. You can see this important procedure at 13:20 – 13:35 timemark in the video.

ZERO Turret Press Has Very Smooth Operation
Gavin observed that this ZERO turret is both smooth and very precise, thanks to smart engineering and the use of multiple bearings. Area 419 describes the design features:

— Turret (zero-slop) eliminates variability induced when removing and resetting dies
— The turret head holds nine 7/8×14-threaded dies (1-1/4 thread in future)
— Available ram-stroke here is 4.4″, allowing use of very tall cartridge types.
— Adjustable/interchangeable handle setup for maximizing leverage/feel based on operation
— Internally contained primer-catch system, slide-out drawer

Important Features of ZERO Turret Press

Area 419 Zero reloading turret 10 station reloading press ultimatereloader review gavin gear

1. Press frame: 6061 Aluminum, clear anodized
2. Wedge clamp (locks turret into indexed position)
3. Turret (7075 aluminum and steel construction)
4. Adjustable handle with roller knob (set either left- or right-handed operation)
5. Bearings: Ball bearing plus roller thrust bearings for side plates
6. Ram riding in self-lubricated linear bearing
7. Spent primer catcher drawer

Milled from American billet aluminum and stainless steel, this press employs 14 bearings, including a self-lubricating linear sleeve bearing for the precision-ground 1.25″ ram. The linkage system also glides on bearings providing smooth operation with near-ZERO slop. The oversized ram features a 0.75″-diameter steel arm and ZERO-friction knob. The turret system is located with an oversized ball-detent system and secured using an over-sized, custom-made ZERO-point pull-stud. Locking the turret after indexing require only a half-turn of the supplied T-handle (see photo above). When indexing the turret, repeatability variance of the system should be less than .0005″.

The opening in the press will allow for sizing and seating of cases up to .338 Lapua Magnum, and will accept standard 7/8″ dies and standard shellholders. NOTE: Area 419 now offers a shellholder system with six precision headspace inserts that allow you to precisely tune shoulder bump when using the ZERO press: “With the new ZERO Modular Shellholder System you can set up your shellholder to your die and have more consistency, more repeatability, and less hassle.”

SUMMARY — Impressive Press Delivers Precise Results
Gavin Gear was very impressed with Area 419’s new Zero Press, which he said offers the precision of a quality single-stage with the versatility of a turret: “There will always be people that prefer a traditional single-stage. Where the ZERO will be compelling is to those who want the precision of a single-stage without the need to screw dies in and out. Leaving your dies set can have benefits for precision as well — everything comes back to the ‘same place’ when dies are indexed into position. Screwing dies in and out can impose variation, and variation is the enemy of the ‘white lab coat shooter’. I plan on testing the ZERO press with ultra-high-end dies, and custom dies that I ream to my own specifications. I’m thinking that will show the true potential of this press!”

Lock-Out Die Blocks Improper Charges with Progresssive Presses


The RCBS Lock-Out Die can also be used with some Dillon and Hornady progressive presses.

RCBS Lock-out dieIf you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works. Your Editor uses it on his RCBS 2000 progressive press. I can affirm that a Lock-Out Die has “saved my bacon” a half-dozen times over the years when there was an over-charge (which could cause a Kaboom) or a low charge (which could cause a squib load).

The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.

RCBS Lock-out dieIt takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.

While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive (see video below) or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). The RCBS 2000 has one more station than a Dillon 550/650, so it’s an ideal platform for using the Lock-Out Die.

On the UltimateReloader.com website, run by our friend Gavin Gear, you’ll find an excellent two-part series on the function and set-up of the RCBS Lock-Out Die. Part One explains how the Lock-Out Die functions, using cut-away illustrations. Part Two shows how to install and adjust the Lock-Out Die on various progressive presses. The Ultimate Reloader video at the top of this article shows setup of the RCBS Lock-Out Die on the Dillon XL-650 progressive press, while the Reloading Bench video below shows the Lock-Out Die on a Hornady LnL progressive.
