L.E. Wilson Case Gage Depth Micrometer Tool Hands-On Tool Review by F-Class John
Are you looking for a better way to measure shoulder bump when sizing brass? When it comes to measuring your shoulder bump there has traditionally been just one way to do it and that’s with a set of calipers and some type of tool attached to a calipers jaw which contacts the case shoulder. While this method has worked well for decades there’s always been some inherent lack of consistency and repeatability. While a minor issue, the inability to get the exact number in completely dependent on the user’s pressure applied and the angle at which the jaws push on the brass.
Enter the L.E. Wilson Case Gage Depth Micrometer with its simple but effective use of Wilson case gauges to ensure a perfect measure of shoulder bump every time. The unit comes with the micrometer top as well as a check gauge which allows you to easily calibrate the micrometer whenever needed. On top of the micrometer unit, you’ll also need to purchase the appropriate case gauges for each of your cartridge types and then you’re ready to go. No other measuring instruments are needed (yep, no calipers are required).
Using the Wilson Depth Micrometer (perhaps a better name is Shoulder Bump Micrometer) is a straightforward process. Simply take your fired brass and insert it into the case gauge and place the micrometer top onto the primer side of the gauge. While holding the micrometer top firmly against the case gauge in one hand, slowly turn the micrometer until you feel it stop. You can back off and turn it again to verify the stop point and once you have it, look at the measurement on the micrometer. Now insert a sized piece of brass and repeat the procedure. Take note of the new number and subtract it from the fired brass number and you now have an exact amount of shoulder bump. Continue to adjust your sizing die until you have the correct amount of shoulder bump and you’re ready to size all your brass.
Watch Video to See how Shoulder-Bump Measuring Micrometer Tool Works
Guys, in this case a VIDEO is worth more than a thousand words. In may not be obvious from the photos how this system works. In fact, it is fast and easy. Drop brass into cartridge-specific case gauge, then put the Micrometer unit on top, and dial to touch. The video shows how this works.
SUMMARY — Tool is Fast, Precise, Repeatable, and Easy to Use — We Like It
The beauty of this tool is the simplicity with which it works. It uses a very accurate micrometer to simply measure how much further your brass is sitting forward inside the case gauge. After a couple uses, you’ll find that this tool is fast, accurate and incredibly repeatable. That gives you confidence that your brass is being sized properly. Ultimately, I found that using the micrometer top really became a joy as I set up a new set of dies and as I sized my brass, I could easily check the consistency as brass came off my press. If you’re looking to improve your sizing game, give the L.E. Wilson Case Gage Depth Micrometer a try. MSRP is $140.00.

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.
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 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.
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
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.
In June 2020, Hornady introduced the 6mm ARC, a new SAAMI cartridge optimized for AR-platform rifles*. The new 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. That pushed-back shoulder does reduce case capacity (and velocity), but we assume Hornady did that to create a shorter, proprietary chamber so people could not simply neck-down Lapua 6.5 Grendel brass, as has been done for years with Robert Whitley’s outstanding 6mm AR wildcat.
What Is the 6mm ARC Cartridge? The 6mm ARC cartridge is a new SAAMI-spec cartridge based on the 6.5 Grendel case necked down for 6mm bullets, with the shoulder moved back 0.030. Yes it is designed to run in AR15-platform rifles. You’ll need a new barrel, bolt, and mags. If you already have an AR chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else — bolt, magazines, gas system – is compatible with 6mm ARC.
▶ Official SAAMI Cartridge (not wildcat)
▶ Fits standard AR15-platform rifles
▶ Fits Short/Mini action bolt rifles
▶ Efficient short, fat case design
▶ 30-degree case shoulder
What Do I Need To Shoot the 6mm ARC?
Faxon and Ballistic Advantage are already producing barrels, with more manufacturers sure to follow. All the other required components are already on the market for 6.5 Grendel rifles. Aero Precision already offers complete 6mm ARC uppers.
If you’re converting a standard 5.56×45 mm (.223 Rem) AR15 upper to shoot 6mm ARC, you’ll need a 6mm barrel, a Type II 6.5 Grendel bolt carrier group, and new magazines. Some folks have suggested standard AR mags will work, but trust us, you want the magazines that have been designed for 6.5 Grendel. Most of the hardware you need is available at Brownells.
* While 6-6.5 Grendel shooters are known to run stout pressures, the new 6mm ARC cartridge has a relatively moderate Maximum Average Pressure (MAP) rating of 52,000 psi according to the official SAAMI specifications. For a variety of reasons, is wise to keep pressures in a semi-auto rifle moderate. Don’t chase the velocities you might get in a bolt-action gun.
Sierra Bullets has released load data for the 6.5 Grendel, a popular cartridge that works equally well in bolt guns and AR15-platform gas guns. Sierra published comprehensive 6.5 Grendel load data, covering 19 powders and eight (8) different bullets from 85 to 130 grains. NOTE: Hornady-brand brass (see below) was used for Sierra’s 6.5 Grendel tests, not the stronger Lapua 6.5 Grendel brass. Hand-loaders using Lapua 6.5 Grendel brass may need to adjust their loads. Also Winchester WSR primers were used. We imagine most precision hand-loaders will prefer CCI or Federal primers.
Sierra Bullets Tested for 6.5 Grendel Load Data
85gr HP (#1700)
100gr HP (#1710)
107gr HPBT (#1715)
In developing its 6.5 Grendel load data, Sierra tested a very wide selection of propellants, 19 in all. For the 85gr to 100gr varmint bullets, modern powders such as XMR 2230, Power Pro Varmint, and Ramshot TAC offered the best velocity in the 24″ test barrel. For the heavier 120gr to 130gr match bullets, Sierra tested a selection of powders. Highest velocities came with Power Pro Varmint and TAC. If you’re looking for best accuracy, consider the slower burn-rate powders such as IMR 8208 XBR and Varget — but you’ll sacrifice some speed. Overall, Sierra’s latest 6.5 Grendel load data is an excellent addition to the 6.5 Grendel knowledge base. Thanks Sierra!
Here are Sierra’s 6.5 Grendel Load Data Charts for Sierra’s 123gr HPBT, 130gr HPBT, and 130gr TMK. There are a five other tables for lighter-weight Sierra bullets.
History of the 6.5 Grendel Cartridge
The 6.5 Grendel originated as a 6mm PPC necked up to 6.5 mm. After Alexander Arms relinquished the “6.5 Grendel” Trademark, the 6.5 Grendel was standardized as an official SAAMI cartridge. It has become popular with target shooters and hunters alike because it is accurate, efficient, and offers modest recoil. Good for small to medium game, the 6.5 Grendel is available in lightweight hunting rifles, such as the Howa Mini Action Rifle. And the 6.5 Grendel is one of the most accurate cartridges suitable for modern AR-15 platform rifles.
On the Applied Ballistics Facebook Page, there was a fascinating series of posts showing traces of bullets at various speeds from Mach 0.86 to Mach 3.0. At the slowest speed, Mach 0.86, i.e. 962 FPS, there is turbulence behind the bullet, but no clear shockwave. At the highest velocity, Mach 3.0 (3375 FPS at sea level, 68° F), there is a dramatic double nose and tail wave formation.

Mach 3.00 Bullet Flight Image
At Mach 3 (3355 FPS) this bullet now has a strong and well established shock wave forming at the tip, and at the base. Unlike the transition through Mach 1.0, nothing really interesting happens to the aerodynamics or shock waves meaning the aerodynamics and stability are: continuous, easy to predict, and model. As you go faster, the shockwaves make a shallower angle because the bullet is moving forward 3X faster than the shock wave is moving away from it. So the shock wave makes an angle that has a rise/run ratio of 1/3.
If a bullet flew within 10 feet of you traveling this fast, it would be about as loud as a 22 magnum. You’d certainly want hearing protection as the energy contained in a Mach 3 shock wave is high! How high…? Well, in 10 yards, this bullet slows from 3355 FPS to 3334 FPS in a time of 0.0090 seconds. The 55 ft-lb of kinetic energy lost during this 10 yards is due to aerodynamic drag on the bullet, which is comprised of wave, base, and skin friction drag components with the majority of the drag being due to shock wave formation. Expending 55 ft-lb of energy in 0.0090 seconds requires a power output of 6111 ft-lb/sec = 11.1 horsepower, most of which goes into creating the shock wave. Remember it’s a 3-D cone that travels great distance, and it gets its energy by stealing velocity from your bullet!
Mach 1.00 Bullet Flight Image
Many shots were fired to capture an image of the transonic shockwave structure at exactly Mach 1.00. With the bullet now moving at the speed of sound, the local airflow on some parts of the bullet exceeds Mach 1.0. Anytime something is moving thru the air faster than the air can get out of the way, you get a compression wave, aka “shock wave”. That’s what’s visible in this image — the areas where the air density changes rapidly (in the compression wave) are visible as near vertical lines and a detached bow wave out front. As the bullet progresses through transonic speed, this shockwave structure develops which has strong effects on the drag (wind sensitivity) and stability of the bullet.
The exact development of the shockwaves and the resulting effects are unique and sensitive to the bullet geometry, and become very difficult to predict through the transition from subsonic (incompressible flow without shock waves) to supersonic (compressible flow with shock waves). Each bullet geometry does this differently which is why it’s difficult to determine transonic stability criteria for bullets of different shapes.
Mach 0.86 Bullet Flight Image
Here’s a bullet at Mach 0.86 (86% the speed of sound, which is 962 FPS at 61° F). As you can see, this 0.86 Mach is not fast enough to make any discernable waves but you can see turbulence in the bullet wake (right side in photo). The beginning of small shock waves can be seen on the bullet tip, and at the bearing surface/boat tail juncture. For the most part, all of the airflow around this bullet is subsonic. You wouldn’t hear a supersonic ‘crack’ from this bullet flying past the observer.
The famed Bianchi Cup pistol match is featured today on Shooting USA television. This event, the top action pistol match on the planet, celebrates its 45th year in 2025. The CMP Bianchi Cup attracts the world’s leading pistol shooters, and this year the Cup added a new .22 LR rimfire pistol division. Adding rimfire competition is a big, positive update to this venerable competition.

Bruce Piatt Wins 2025 Bianchi Cup
At the 2025 Bianchi Cup competition, Legendary competitive shooter and Team Vihtavuori member Bruce Piatt claimed his eighth Bianchi Cup title, securing victory at the 2025 Bianchi Cup with the only perfect score of 1920 in the match.
The Civilian Marksmanship Program (CMP) now oversees the Bianchi Cup competition, previously run by the National Rifle Association. The 2025 Civilian Marksmanship Program (CMP) Bianchi Cup, known as the gold standard in action pistol shooting, was hosted once again at the Green Valley Rifle and Pistol Club in Hallsville, Missouri, May 20-23, 2025. Participants from all over the world competed in the Falling Plates, Moving Target, Barricade, and Practical events.
This video features the 2025 CMP Bianchi Cup at the Green Valley Rifle and Pistol Club in Hallsville, Missouri. This video showcases the new class for .22 LR pistols. Watch talented rimfire pistol competitors firing .22-caliber pistols at steel plates. The new rimfire class allows much more affordable competition. High quality .22 LR match ammo is available for $11.50 for 50 rounds (just 23 cents/round). By contrast, a good box of .38 SPL match ammo can cost $0.60 to $1.10 per round (or more).
What if you could see a speeding bullet in the milliseconds it exits the muzzle of a pistol? How cool would that be… Well, the Mythbusters folks (Adam Savage and Jamie Hyneman) have made that possible. Using an exotic Phantom super-high-speed camera running at 73,000 frames per second, the Mythbusters recorded a .45 ACP bullet being fired from a 1911-type handgun.
Watch Mythbusters Super-Slow-Motion Pistol Video:
Watch this FULL SCREEN to see the amazing details of the flame and smoke exiting the muzzle.
What unfolds is spectacular. First you see a ball of flame as the bullet emerges from the barrel of the 1911, then two distinct, separate swirling clouds form as the bullet races toward the target. Watch the video a couple times — it’s mesmerizing.
Co-host Adam Savage is nearly rendered speechless by the remarkable slow-motion footage from the Phantom. Filmed at 73,000 frames per second, the video reveals a dance of pressure and fire that would otherwise be missed by the unaided eye.

Shown is the Redding Model 15-P Competition Piloted Inside Chamfering Tool with pilot rod that centers in the case flash hole. Also shown is a Forster 45° Rocket Tool.
There are a wide variety of reloading tools designed to cut a slight chamfer in case necks and deburr the edge of the case mouth. You don’t need to spend a lot of money for an effective tool. A basic “rocket-style” 45° chamfering tool, such as the Forster, actually does a pretty good job taking the sharp edge off case mouths, particularly if you use a little scotch-pad (or steel wool) to smooth the edge of the cut. The Forster chamfer tool, shown below, is a nicely-made product, with sharper cutting blades than you’ll find on most other 45° chamferers. It costs $26.99 at Brownells.com.
Redding sells a handy piloted chamfering tool with a 15° inside cutting angle and removable accessory handle. This Redding Model 15-P chamferer works really well, so long as you have consistent case OALs. The pilot rod (which indexes in the flash hole) is adjustable for different cartridge types (from very short to very long). This ensures the concentricity of the inside neck chamfer to the case mouth. This quality tool works with cases from .22 to .45 Caliber, and retails for $42.99 at MidwayUSA.
Sinclair International offers a 28° carbide chamferer with many handy features (and sharp blades). The $29.99 Sinclair Carbide VLD Case Mouth Chamfering Tool will chamfer cases from .14 through .45 caliber. This tool features a removable 28° carbide cutter mounted in the green plastic Sinclair handle.
Many folks feel they can get smoother bullet seating by using a tool that cuts at a steeper angle. We like the 22° cutter sold by Lyman. It has a comfortable handle, and costs just $19.99 at Cabelas.com. The Lyman tool is an excellent value, though we’ve seen examples that needed sharpening even when new. Blade-sharpening is easily done, however.
K&M makes a depth-adjustable, inside-neck chamferer (“Controlled Depth Tapered Reaper”) with ultra-sharp cutting flutes. The latest version, which costs $64.40 at KMShooting.com, features a central pin that indexes via the flash hole to keep the cutter centered. In addition, the tool has a newly-designed handle, improved depth-stop fingers, plus a new set-screw adjustment for precise cutter depth control. We caution, even with all the depth-control features, if you are not careful, it is easy to over-cut, slicing away too much brass and basically ruining your neck. We think that most reloaders will get better results using a more conventional chamfer tool, such as the Forster or Redding 15-P.
One last thing to note — tools like the K&M and the Sinclair chamferer are often described as VLD chamferers. That is really a misnomer, as bullets with long boat-tails actually seat easily with very minimal chamfering. In reality, these high-angle chamferers may be most valuable when preparing brass for flat-base bullets and bullets with pressure rings. Using a 22° or 28° chamferer can reduce the risk of cutting a jacket when using VLD bullets though — so long as you make a smooth cut.
