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. It 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 $130.00.
Bang Clang! The 2023 Steel Challenge World Speed Shooting Championship is featured on Shooting USA TV this week. The Shooting USA Steel Challenge episode runs August 23, 2023 on the Outdoor Channel. Show times are: Wednesdays, 9:00 PM Eastern and Pacific, 8:00 PM Central. After those broadcast times, you can watch the show via Vimeo on Demand for $0.99 per episode.
This past April, the fastest speed shooters in the world showcased their skills at the Steel Challenge Championship at the CMP Talladega Marksmanship Complex in Alabama. The Steel Challenge course consists of eight 5-target close-range stages. This discipline has been called “drag racing with guns”. Draw and shoot 5 steel targets with time as your score. The shooter with the lowest overall time wins. This is a very popular event — when registration opened for the 2023 Steel Challenge, more than 700 slots filled in just 12 minutes.
The 2023 Steel Challenge at Talladega was featured this month on the NRA Shooting Sports USA site.
There are multiple pistol and revolver classes, both rimfire and centerfire, iron sights and optics. Increasing in popularity (and speed) are the rimfire rifle and pistol-caliber centerfire rifle classes. There are 13 gun classes in total, the most for any shooting championship. In the centerfire handgun match, the fastest times are posted by competitors using enhanced open guns with compensators and red-dot optics.
Here is a full length Shooting USA Steel Challenge Episode from 2017:
Shooting USA Video covers Course of Fire, Firearms Classes, and Target Layouts (1:20)
Definitely watch the 4-minute video (above) produced by Shooting USA. It explains the classes, shows the stages, and illustrates ALL the different gun classes, pistol AND rifle. You can also see some of the world’s fastest shooters including Jessie Harrison (1:47, 3:44) and Max Michel (3:48). Be amazed by the speed of semi-auto rimfire rifles — five targets hit in under two seconds!
The Steel Challenge was founded in 1981 by Mike Dalton and Mike Fichman, in Southern California. The two Mikes wanted an exciting alternative to paper targets and came up with the all-steel format. The Steel Challenge World Speed Shooting Championships have grown to one of the largest professional pistol competitions in America. In 2022, scores of competitors competed at the Talladega Marksmanship Park for glory and cash prizes. The Steel Challenge is governed by the Steel Challenge Shooting Association (SCSA) that consists of eight standardized stages with three types of steel targets: small circle, big circle, and square. Here is a steel challenge layout in Germany.
Ruger Super GP100 Revolver in 9mm Luger (9x19mm)
Wouldn’t it be cool if you could shoot your 9mm semi-auto pistol ammo in an ultra-accurate revolver? Well you can. Ruger adapted its existing Super Redhawk frame to create the Super GP100 9mm Luger (9x19mm) revolver. As you can see, the Super GP100 9mm features a stubby 8-round PVD-coated cylinder to better fit the 9x19mm round. According to Guns.com the 9mm GP100 “uses a cylinder and extractor cut for moon clips to speed up reloading [and] sports a 6-inch half-lug sleeved and shrouded barrel with an 11-degree target crown[.]”
Watch this GunBlast video review to see how this unique Ruger 9x19mm wheelgun performs. Reviewer Boge Quinn said this a “competition grade gun” with nice fit and finish. Out of the box the Super GP100 9mm had a 9.5-lb double-action pull and a 4.5-lb single action trigger pull. It took a while for the pull to smooth out Quinn noted. Also, he said that if you do NOT use the supplied moon-clips it is awkward to remove the spent cartridges: “You don’t have to use a moon clip, but I don’t know why you wouldn’t… it just works great that way.”
The 9×19mm Parabellum (aka 9mm Luger) cartridge was introduced in 1902 by German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) for the Luger semi-auto pistol. Now 120 years later, Ruger brings us a sturdy, 6″-barrel revolver for this popular cartridge. Ruger adapted its existing Super Redhawk frame for this Super GP100 9mm revolver. In this video, Ruger engineer Mark Gurney explains the features of the Super GP100 9mm revolver:
Super GP100 9x19mm Features
Triple-locking cylinder locked into the frame at front, rear and bottom for more positive alignment and dependable operation.
High-strength stainless steel cylinder is fluted and shortened to reduce overall mass and increase rotational speed. Cylinder has PVD finish for durability and ease of extraction.
Polished and optimized internals, a centering boss on the trigger, and centering shims on hammer deliver a smooth double-action trigger pull with crisp/consistent let-off.
Cylinder and extractor are cut for moon clips to speed reloading during intense competition. Ships with three full moon clips and moon clip tool. The ejector and chamber mouths have a light chamfer to aid loading with moon clips.
Hogue hardwood grip is hand-finished for a smooth, polished feel. Grip frame accommodates a wide variety of custom grips.
Transfer bar mechanism provides security against accidental discharge.
Cold hammer-forged barrel has precise rifling for accuracy and longevity.
Barrel features 11° target crown for competitive-level accuracy.
.17 HMR and .22 WMR Options Enhance Ruger Precision Rimfire for Varmint Work
Many readers may not know this, but the Ruger Precision Rimfire rifle is available in two additional rimfire chamberings: .17 HMR and .22 WMR. While .22 LR ammo is considerably cheaper, .17 HMR and .22 WMR shoot flatter and deliver much more energy. This makes the Ruger rig way more suitable for varminting. In fact we think this .17 HMR transforms the Ruger Precision Rimfire into a very good “carry-around” varmint rifle. We really like the .17 HMR — it’s our favorite rimfire cartridge for small varmints out to 160 yards.
Both cartridge types, .17 HMR and .22 WMR, also offer higher velocities, less wind drift, and flatter trajectory than the .22 LR. This is a benefit when cross-training. You can shoot at more distant targets with considerably less elevation dialed in your scope. And the windage corrections will be less extreme.
Ruger says: “Faster, flatter and with high-performing bullets, .17 HMR and .22 WMR cartridges expand the capabilities of the Ruger Precision Rimfire platform. Like its .22 LR predecessor, these new magnum offerings maintain the same ergonomics, trigger and manual of arms as the larger centerfire Ruger Precision Rifle.”
Here’s an excellent video review of the .17 HMR Ruger Precision Rimfire rifle by YouTuber 22 Plinkster. The reviewer was impressed with the rifle’s accuracy with 17gr ammo.
Both Ruger Precision Rimfire rifles feature 18″ hammer-forged barrels threaded for muzzle devices, including the Ruger® Silent-SR®. The 15″ free-float handguard with Magpul M-LOK slots provides generous scope clearance and easy mounting of M-LOK-compatible rails and accessories.
Like its .22 LR version, the magnum Ruger Precision Rimfire models featured an adjustable bolt throw (that can emulate a centerfire action if desired), along with trigger that adjusts from 2.25 to 5 pounds. The .17 HMR and .22 WMR models ship with a 0 MOA Picatinny rail and one, 15-round BX-15 Magnum magazine or one, 9-round JMX-1 rotary magazine. The BX-15 Magnum is a natural pairing for the new Ruger Precision Rimfire in magnum calibers. It is also compatible with Ruger 77/17®, Ruger 77/22® and Ruger American® Rimfire rifles chambered in .17 HMR and .22 WMR.
You are looking at a true game-changer — a full-size spotting scope with a digital screen, not a conventional rear glass eyepiece. On the new Omnis Digital Spotting Scope, the large front objective gathers light effectively as does a normal spotter, but you view the image on a digital screen. This has many advantages — multiple persons can view the screen at the same time. You don’t have to get extremely close to the screen as you would with a conventional eyepiece. This is great for a spotter or coach, who can also maintain a broader view downrange in his field of vision.
In addition, digital screen graphics can potentially provide range and ballistics information (via software). Another major advantage is that the screen output can recorded and later replayed for analysis or review. That’s great for training programs or when reviewing match stages — you basically can record a movie of your shooting sessions. And, the system works well at night and in low light, so it is great for hunters. Wouldn’t it be cool if your current spotting scope could be used at night?

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.”

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.
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, has videos whoe Wilson stainless steel case trimmer with micrometer adjustment (photo below). The first video explains the operation of the Wilson trimmer and shows how to initially assemble the tool, attach the handle, and set the cut length.
This second video shows how to set up the stainless Wilson trimmer with micrometer cut-length control. The micrometer 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.
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.
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 know our many of our readers enjoy Prairie Dog varminting safaris. For long P-Dog shots you’ll definitely want a centerfire. We like the 20 Practical in an AR and a 22 BR/BRA in a bolt-action. That will have you covered out to 700 yards. But for shorter shots on small critters — say inside 150 yards — it makes sense to have an accurate 17 HMR rimfire rig. Today’s 17 HMRs are capable of surprising accuracy, rivaling a good centerfire rig, but with way less recoil and much lower cost per shot. And the 17 HMR offers more than double the velocity of a .22 LR — up to 2650 fps with a 17-grain bullet.
Top Shot former Champion Dustin Ellerman likes his Volquartsens, and we can see why. With one of his favorite 17 HMR rimfire varmint rigs, he’s seen some outstanding accuracy with CCI ammo. A few seasons back, on his Facebook page, Dustin reported: “Prepping for prairie dogs and I’m floored by this cold, sub-half-inch group shot with the Volquartsen Custom 17 HMR at 100 yards.” This thumbhole-stock rifle features a Bowers Group USS suppressor, and 3-12x56mm Meopta Scope. Dustin tried different types of CCI 17 HMR ammo. This small group was shot with CCI A17 ammo.
What’s the effective range of a 17 HMR on prairie dogs? You might be surprised. in 2015, Dustin took another Volquartsen 17 HMR on a Prairie Dog hunt in Wyoming. He was impressed with the rifle (shown below) and the little rimfire cartridge. Dustin says the effective range of the 17 HMR is farther than one might expect: “I made hits out to 300 yards. 200 yards was easy as long as the wind wasn’t too bad.”
Here’s the Volquartsen 17 HMR Dustin used in Wyoming in 2015:
After that 2015 P-Dog expedition, Dustin became a fan of the 17 HMR cartridge: “Never paid it much attention before now because the ammo is five times more expensive than .22 LR and I mostly target shoot. However, for prairie dogs, the 17 HMR is amazing!” Consider this — Hornady’s 17 HMR ammo pushes a 17gr V-Max bullet at 2550 fps, twice as fast as typical .22 LR rounds.
Prairie Dog Adventure with Savage A17
This video shows a successful Prairie Dog hunt. Watch and you’ll see hits out to 160 yards (00:50), proving the effective range of the 17 HMR cartridge. The host is shooting a Savage A17 semi-auto 17 HMR rifle in a Boyds laminated stock.
