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.

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, 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.

Rimfire Revolution — Good Resource for NRL22 Competitors

17 HM2 Mach 2 rimfire

Do you shoot NRL22 matches, or are you thinking of getting started in that rapidly-growing discipline? Then grab a copy of Rimfire Revolution: A Complete Guide to Modern .22 Rifles. Released in summer 2021, this book covers rimfire rifles and shooting disciplines. Order the print version for $32.99 from Gun Digest, $35.33 from Amazon Direct. Or get a digital Kindle Edition for $21.29 from Amazon.

This Gun Digest book has become a “go-to” resource for NRL22 and PRS Rimfire shooters. Key topics included in this 2021 Edition full-color Gun Digest book include: rimfire semi-autos and how they work; bolt-action accuracy; match shooting skills; DIY precision gunsmithing; hunting with rimfires; and the future of the rimfire market.

With the growth of rimfire tactical competition, the .22-Caliber rimfire rifle is more popular than ever. Every major gun manufacturer has brought at least one new .22 LR rimfire rifle to the market in the last two years. Gun Digest’s Rimfire Revolution has extensive coverage of new models from major manufacturers.

The .22 Long Rifle (.22 LR) is the planet’s most popular ammunition type and firearm chambering. The .22 LR is used in the Olympics by 3P marksmen, but it also serves benchrest competitors, NRL22 shooters, backyard plinkers, small-game hunters, and tactical trainers. With the expansion of NRL22 matches (and the PRS equivalent), the humble .22 LR is undergoing a major resurgence in the USA. And with centerfire reloading components being so costly and difficult to find, many folks are shooting less centerfire, but way more rimfire.

Plus Coverage of .17-Caliber Rimfire Rifles — 17 HM2, 17 HMR, 17 WSM
This 272-page book also covers .17-caliber rimfire cartridges: 17 HM2 (Mach 2), 17 HMR, and 17 WSM. These are all excellent varmint rounds, with the 17 WSM effective out to 250 yards. The 17 HM2 will run in a normal .22 LR action and feed from standard .22 LR magazines. So, for most rifles, all you need to do a .22 LR to 17 HM2 conversion is a barrel switch. That gives your rimfire rig twice the versatility. Shoot .22s and .17s with the same gun.

NRL22 — Challenging Practical Competition with .22 LR Rifles

The USA has seen a big growth in rimfire tactical matches over the last five years. Right now there are probably ten times as many rimfire tactical matches as sanctioned PRS and NRL centerfire matches. The reason is simple — rimfire ammo is much less costly, and clubs can run challenging rimfire tactical matches at nearly any outdoor gun range that allows shooting out to 200+ yards.

NRL22 Competition — Tactical Rimfire Matches
The NRL22 match format is a great shooting discipline. NRL22 offers a high fun factor at relatively low cost. You don’t have to reload match ammo. A couple of 50-round boxes of .22 LR ammo will get you through the match. While some people bring lots of gear to matches, that’s by choice and not by necessity. You can keep it simple and still be competitive (and win).

Tips for NRL22 Competitors
by Jonathan Ocab
I am a match director at my gun club and run our local NRL22 matches. People often ask me for tips for competing in NRL22. First, I recommend getting the course of fire for the month in advance and practicing those stages at the range. Here are other specific tips that should help NRL22 competitors improve their gun-handling and match results.

1. Dry Fire Practice — If you are not able to do live fire practice at the range, I encourage shooters to practice their shooting positions at home via dry fire. Setup props or barricades with pasters or other faux targets on a wall in the garage or inside the house and run through each stage.

2. Scope Magnification Level — The most common issue I see with newer shooters in NRL22 is the tendency to maximize their scope magnification. The timer will start, and the shooter gets into position on a target, but the scope is set to 15x or higher and the shooter can’t find the target. The shooter lowers the magnification, locates the target, and then increases the magnification again, takes the shot, transitions to another target, and repeats the process of decreasing magnification, locating target, etc. Novice NRL22 shooters should try using the mid-range magnification. Try shooting 7x-12x and learn to balance field of view and target image.
