Folks who load at the range need to bring a lot of gear — reloading presses, powder dispensers, scales, funnels, sizing/seating dies, brass prep tools and more. And there may be other important items to transport — such as ammo caddies, LabRadar mounts, over-size rest feet, and even barrel fans.
A rifle case works fine for carrying your scoped rifle, but you still need to organize all your reloading tools and other gear, and transport them safely from home to range and back again. Some guys have built their own loading tool-boxes from wood. Other may stuff gear in a couple of plastic range boxes. But clever Chris Covell came up with an even better solution.
Chris sourced a handsome, sturdy metal Horse Grooming Box from eBay. Chris reports the multi-feature metal box “works perfectly for reloading. My ChargeMaster is now out of the wind.”
Bullets, Trickler, and Priming Tool on Top
On top, below the hinged metal lid, is a large compartment that holds Covell’s funnels, scales, priming tool, trickler and other vital gear (photo on right). This top compartment is deep enough to handle wide-mouth funnels with no problem.
Slide-Out Drawer with Dividers
Below the top level is a handy sliding drawer with multiple dividers. This is perfect for holding Covell’s inline seating dies, case-neck deburring and chamfering tools, among many other smaller bits and pieces.
In the bottom of the Horse Grooming box is a large compartment that holds bigger gear. In the bottom section, Covell places his RCBS Chargemaster Lite, along with a case-trimming tool, an arbor press, and various other bulky tools. Check it out:
Chris Covell’s Range Box was featured on the Benchrest Shooting and Gunsmithing Private Group Facebook Page. You may want to sign up for this Group — with membership you can access a wealth of information for accuracy-oriented shooters.

There’s a nice article in the Western Powders Blog that any varminter will enjoy. In this hare-raising tale, gunwriter Jim Waddell explains how he used a self-loading Savage A17 rifle to take care of a serious jack-rabbit problem on a rancho in California. “[My friends] purchased a huge amount of acreage that had some existing alfalfa fields and [surrounding sagebrush]. Sagebrush is home to jack rabbits. Lots of jack rabbits. The previous owner of this property didn’t do any varmint or predator control[.] The ink wasn’t dry on the escrow papers before [my friends] started asking for help shooting rabbits. A problem in taking these critters is it has to be done at night when they come out to feed as they lay low in the bush during the daylight hours.”
Savage A17 Comes to the Rescue
Initially Waddell and some friends took on the jack-rabbit hordes using Ruger 10/22s and a .44 Magnum Marlin lever gun. Neither option was ideal. The .44 Magnum just couldn’t keep up the desired shooting pace (it took too long to reload) ant the .22 LRs were too anemic. So Waddell decided to give the more potent 17 HMR a try. He acquired a Savage A17 and went back for a second bunny-busting session. He came away convinced that the 17 HMR cartridge in the modern semi-auto Savage works great for small varmint control.
Waddell writes: “I wanted more than a .22 after seeing the problems my pals had with their [10/22] bullets not anchoring the rabbits. Armed with my new Savage A17 it was time to head back to the alfalfa fields. This time my hunting partner was Dan, my son-in-law from Seattle. We hunted for four nights. Each night was either raining, windy or both. My question about whether or not rabbits would be out in the weather was answered immediately. They were everywhere. As miserable as the weather was, we got all the shooting we wanted and that Savage rifle was up to the task. We got so many rabbits it was impossible to count.” CLICK HERE for the full account of Waddell’s jack-rabbit adventures on the California rancho. It’s worth a read. Here is a sample:
Wabbits, Wabbits Everywhere — Even Running Right at You
I couldn’t believe my eyes when I saw a sea of rabbits as far as the lights would shine and when the light beams hit the bunnies, they became confused and as often as not, would run right at the lights so a good percentage of our shots were literally in spitting distance. It was also a new experience shooting at targets that are running TOWARD you. Most of us who’ve done much hunting for game or varmints have experienced moving targets but how many of those targets are coming at you?
For centerfire ammo, you can choose from dozens of flip-top boxes, storage bins, or milsurp-style ammo cans. For rimfire ammo, there are not so many good choices. Our preferred rimfire ammo carrier is the MTM SB-200 Small-Bore Fitted Ammo Box. This flip-top plastic box holds 100 rimfire rounds in 10×5 black grids on the left and right. In the center is a storage area that will hold another 100 rounds in factory boxes.
Versatility for ALL Types of Rimfire Ammo
MTM’s SB-200 box is not just for .22 LR ammunition. This handy carrier will hold 17 HMR rounds, as well as 17 Mach 2, 22 short, 22 Win Mag Rimfire, and of course 22 Long Rifle (.22 LR). This box is a winner — it’s low profile, holds rounds securely, and the center storage feature is smart.
MTM Case-Gard 200 Round Smallbore Box
This is really the only product of its kind on the market. It allows you to conveniently and securely hold 200 rimfire rounds, and also segregate your ammo by brand or bullet type. These boxes fit all types of popular rimfire ammunition. The vertical clearance of the lid is sufficient to hold the longer .22 WMR Rounds, and 17 HMR (as well as .22 LR naturally). The lid fits securely so you don’t have to worry about your rimfire ammo spilling out on the way to the range.
If you don’t have one of these boxes yet, we recommend you order one or two. They cost less than $15.00 and are available in Blue or “Rust” (a brick color).
“If the hunter does his part, the .270 will not let him down” — Jack O’Connor.
Classic hunting rifles never go out of style. We thought our readers would enjoy this very special high-grade Jack O’Connor Tribute rifle in .270 Winchester. This unique Model 70 was a SHOT Show featured rifle back in 2013. It was auctioned off with the proceeds benefiting hunting and shooting sports. Jack O’Connor, a legendary outdoorsman and hunting writer, would have been proud. In his 1964 classic work The Rifle Book, O’Connor wrote: “I like a handgun. I hold a shotgun in high regard; but rifles — well, I love the darn things…”
Winchester Repeating Arms declared that this 2013 SHOT Show Winchester Model 70 would be the last-ever Jack O’Connor Tribute rifle. The stock for this rifle is AAA grade Claro Walnut with Ebony forearm tip and shadowline cheekpiece. The rifle’s metalwork has been hand-engraved by the artisans at Baron Engraving. The rifle features a featherweight contour, free-floating barrel with target crown. Interestingly, the Leupold 4X Mountaineer riflescope mounted on this rifle is an original 1950s-era Mountaineer from the vaults of Leupold & Stevens.

“A good sporting stock should enable the shooter to get a shot off quickly and accurately, and it should also be a thing of beauty. Many fine sporting stocks are handsome but of little aid in accurate shooting. Many others that hold and shoot well are homely and clumsy.
The very best sporter stock design results in a stock with handsome, graceful lines and one which also enables the man behind it to do his best work.” — Jack O’Connor, The Big Game Rifle (1952).
About Jack 0’Connor “Dean of Outdoor Writers”
Jack O’Connor, sheep hunting, and the Model 70 Winchester in .270 are linked in our collective subconscious. In 1939, O’Connor was appointed new guns editor for Outdoor Life, and in 1941, he took over the Arms and Ammunition column. In those days, Coues deer and desert sheep were his passions, and a lot of rifles came and went through his hands. By the end of 1946, O’Connor had hunted enough North American sheep to complete three grand slams.
By 1954, he thought he had his ultimate rifle, a custom Model 70 in .270 Winchester that he had taken to Wyoming for elk, to India for blackbuck, and to Iran for red sheep and ibex. He liked the rifle so much, he called it his No. 1 and set out to build a second to give his favorite a break from testing new bullets and developing loads.
Sporting Classics offers a collection of great Jack O’Connor stories from the pages of Outdoor Life, Field & Stream, Petersen’s Hunting and other popular magazines of his day. This 440-page book, entitled Classic O’Connor: 45 Worldwide Hunting Stories, is a sequel of sorts to Sporting Classics’ popular compendium, The Lost Classics of Jack O’Connor.
In this collection, Jack O’Connor recounts his worldwide hunting adventures, during which he pursued everything from ducks to grizzlies, pheasants to kudu. Classic O’Connor presents several of the author’s greatest gun stories and a large selection of never-before-published photographs of the celebrated sportsman and his family on hunting adventures around the world. The book is illustrated with 40+ drawings by acclaimed artist Ron Van Gilder. This excellent O’Connor collection is available on Amazon in hardcover or paperback, starting at $38.99 (used) or $59.98 (new).
The Hunting Rifle by Jack O’Connor
Another O’Connor title worth reading is The Hunting Rifle, still considered one of the definitive works on selecting a hunting rifle and cartridge. One owner of The Hunting Rifle explains:
“It would benefit every hunter to take the time and read this book. It offers a corrective to the spirit of things that have gripped the hunting scene lately. Today, if one reads a hunting magazine, [one is] offered the view that you need the fastest and loudest cartridges, rifles with special finishes and the most expensive of anything. Ole Jack reminds us that many have killed game with ‘lesser’ guns for a very long time, and that these new gimmicks will not make you a more lethal hunter.”

Tumblers and walnut/corncob media are old school. These days many shooters prefer processing brass rapidly with an ultrasonic cleaning machine. When used with the proper solution, a good ultrasonic cleaning machine can quickly remove remove dust, carbon, oil, and powder residue from your cartridge brass. The ultrasonic process will clean the inside of the cases, and even the primer pockets. Tumbling works well too, but for really dirty brass, ultrasonic cleaning may be a wise choice.
Our friend Gavin Gear recently put an RCBS Ultrasonic cleaning machine through its paces using RCBS Ultrasonic Case Cleaning Solution (RCBS #87058). To provide a real challenge, Gavin used some very dull and greasy milsurp brass: “I bought a huge lot of military once-fired 7.52x51mm brass (fired in a machine gun) that I’ve been slowly prepping for my DPMS LR-308B AR-10 style rifle. Some of this brass was fully prepped (sized/de-primed, trimmed, case mouths chamfered, primer pockets reamed) but it was gunked up with lube and looking dingy.”
UltimateReloader.com Case Cleaning Video (7.5 minutes):
Gavin describes the cleaning exercise step-by-step on UltimateReloader.com. Read Gavin’s Cartridge Cleaning Article to learn how he mixed the solution, activated the heater, and cycled the machine for 30 minutes. As you can see in the video above, the results were impressive. If you have never cleaned brass with ultrasound before, you should definitely watch Gavin’s 7.5-minute video — it provides many useful tips and shows the cleaning operation in progress from start to finish.
Ultra Dry Necks After Ultrasonic Cleaning — Some Suggestions
The Ultrasonic cleaning process gets cartridge brass so “squeaky clean” that increased force may be required to seat your bullets, or they may “grab” as they go in the necks. To reduce bullet-seating effort, you may benefit from adding a little dry case lube inside the case-neck before loading (use a nylon brush). Another trick is adding a teaspoon of Ballistol lube to the cleaning solution. That provides a trace lubricant inside the necks, but does not interfere with powder ignition in any way.
The latest Gen2 RCBS ultrasonic cleaning machine has a large 6.3-quart capacity. That’s nearly 100 percent larger than the first generation machine in Gavin’s video. The Gen2 machine, $322.02 on Amazon, features a second ceramic heater and transducer to better clean brass cases and firearm parts. The LED is easily programmable, and the timer can be set for up to 30 minutes of cleaning. The original 3.2 quart capacity RCBS ultrasonic machine, as shown in Gavin’s video, is still available for $166.56 at Midsouth Shooters.

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 $20.99 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 ($35.99 at Brownells) works with cases from .22 to .45 Caliber.
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. It is on sale right now for $24.99 at Brownells. NOTE: A hex-shaft cutter head power adapter can be purchased separately for $14.99 (Sinclair item 749-002-488WS). This can be chucked in a power screwdriver or used with the Sinclair Case Prep Power Center.
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 $11.54 at Midsouth Shooters. 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 $51.70 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.

In our Shooters’ Forum, one member recently asked: “What makes an AR accurate? What parts on an AR can really affect accuracy — such as free-floating handguards, barrels, bolts, bolt carriers?” He wanted an honest, well-informed answer, not just sales pitches. Robert Whitley posted a very comprehensive answer to this question, based on his experience building and testing dozens of AR-platform rifles. Robert runs AR-X Enterprises, which produces match-grade uppers for High Power competitors, tactical shooters, and varminters.
Building an Accurate AR — What is Most Important
by Robert Whitley
There are a lot of things that can be done to an AR to enhance consistent accuracy, and I use the words “consistent accuracy” because consistency is a part of it (i.e. plenty of guns will give a couple great 5-shot groups, but won’t do a very good 10- or 20-shot groups, and some guns will shoot great one day and not so good on others).
Here are 14 key things we think are important to accuracy.
1. Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut. The extension threads must also be cut true to the bore, with everything true and in proper alignment.
2. Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy. The typical AR upper receiver was made for a lightweight carry rifle and they stripped all the metal they could off it to make it light to carry (which is advantageous for the military). The net result are upper receivers that are so thin you can flex them with your bare hands. These flexible uppers are “strong enough” for general use, but they are not ideal for accuracy. Accuracy improves with a more rigid upper receiver.
3. True Receiver Face: We’ve found that truing the receiver face is valuable. Some may argue this point but it is always best to keep everything related to the barrel and the bore in complete alignment with the bore (i.e. barrel extension, bolt, upper receiver, carrier, etc.).
4. Barrel Extension: You should Loctite or glue the barrel extension into the upper receiver. This holds it in place all the way front to back in the upper receiver. Otherwise if there is any play (and there typically is) it just hangs on the face of the upper receiver completely dependent on the face of the upper receiver as the sole source of support for the barrel as opposed to being made more an integral part of the upper receiver by being glued-in.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
6. Free-Float Handguard: A rigid, free-float handguard (and I emphasize the word rigid) really makes a difference. There are many types of free-float handguards and a free-float handguard is, in and of itself, a huge improvement over a non-free-float set up, but best is a rigid set-up. Some of the ones on the market are small diameter, thin and/or flexible and if you are shooting off any type of rest, bipod, front bag, etc., a rigid fore-end is best since ARs want to jump, bounce and twist when you let a shot go, as the carrier starts to begin its cycle before the bullet exits the bore.
7. Barrel Contour: You want some meat on the barrel. Between the upper receiver and the gas block don’t go real thin with a barrel (we like 1″ diameter if it’s workable weight-wise). When you touch off a round and the bullet passes the gas port, the gas system immediately starts pressuring up with a gas impulse that provides vibrations and stress on the barrel, especially between the gas block back to the receiver. A heavier barrel here dampens that. Staying a little heavier with barrel contour through the gas block area and out to the muzzle is good for the same reasons. ARs have a lot going on when you touch off a round and the gas system pressures up and the carrier starts moving (all before the bullet exits the bore) so the more things are made heavier and rigid to counteract that the better — within reason (I’m not advocating a 12-lb barrel).
8. Gas Tube Routing Clearance: You want a gas tube that runs freely through the barrel nut, through the front of the upper receiver, and through the gas key in the carrier. Ensure the gas tube is not impinged by any of them, so that it does not load the carrier in a stressed orientation. You don’t want the gas tube bound up so that when the gas tube pressures up it immediately wants to transmit more force and impulse to the barrel than would normally occur. We sometimes spend a lot of time moving the gas block with gas tube on and off new build uppers and tweaking gas tubes to get proper clearance and alignment. Most gas tubes do need a little “tweaking” to get them right — factory tubes may work OK but they typically do not function optimally without hand-fitting.
9. Gas Port Tuning: You want to avoid over-porting the gas port. Being over-gassed makes the gas system pressure up earlier and more aggressively. This causes more impulse, and increases forces and vibration affecting the top end and the barrel. Tune the gas port to give the amount of pressure needed to function properly and adequately but no more.
10. Front/Back Bolt Play: If accuracy is the game, don’t leave a lot of front/back bolt play (keep it .003″ but no more than .005″). We’ve seen factory rifles run .012″ to .015″ play, which is OK if you need to leave room for dirt and grime in a military application. However, that amount of play is not ideal for a high-accuracy AR build. A lot of front/back bolt play allows rounds to be hammered into the chamber and actually re-formed in a non-consistent way, as they are loaded into the chamber.
11. Component Quality: Use good parts from a reputable source and be wary of “gun show specials”. All parts are NOT the same. Some are good, some are not so good, and some aftermarket parts are simply bad. Don’t be afraid to use mil-spec-type carriers; by and large they are excellent for an accuracy build. Also, remember that just because a carrier says “National Match” or something else on it does not necessarily mean it’s any better. Be wary of chrome-plated parts as the chrome plating can change the parts dimensionally and can also make it hard to do hand-fitting for fit and function.
12. Upper to Lower Fit: A good upper/lower fit is helpful. For quick and dirty fit enhancement, an Accu-Wedge in the rear helps a lot. The ultimate solution is to bed the upper to a specific lower so that the upper and lower, when together, are more like one integral unit. For the upper receivers we produce, we try to get the specs as close as we can, but still fit the various lowers in the market place.
13. Muzzle Attachments: Don’t screw up the muzzle (literally). Leave as much metal on the barrel at the muzzle as you can. People like to thread the muzzle for a flash hider, suppressor, muzzle brake, or some other attachment, but if you really want accuracy, leave as much metal as you can there. And, if you have something that screws on, set it up so that it can be put on and have it stay there without putting a lot of torque and stress on it right where the bullet exits the bore. If you are going to thread the end of the barrel, make it concentric with the bore and make sure what you screw on there is as well. For all muzzle attachments, also ensure that the holes through which the bullet passes through are dead true to the bore. Many aftermarket screw-on things are not so good that way. Anything that vents gas should vent symmetrically (i.e. if it vents left, it should vent equally right, and likewise, if it vents up, it should vent down equally). Uneven venting of gas can wreck accuracy.
14. Quality Ammunition: Ammo is a whole story by itself, but loads that are too hot typically shoot poorly in an AR-15. If you want accuracy out of an AR-15, avoid overly hot loads. Shown below are test groups shot with four (4) different uppers, all with moderate loads. These four uppers all pretty much had the same features and things done to them as explained in this article, and they all shot great.
New Year’s Eve is just four days away. Perhaps you’ve been getting ready for the big event, getting Champagne (and sparklers) to celebrate the New Year, and the opening of a new decade. 2020 will also be a Presidential election year, by the way — so make sure you’re registered to vote.
Recently at Thorton Winery in Temecula, California, a champagne vintner, we were shown the best way to open a champagne bottle. We were told you should hold the bottle nose up at an angle then rotate the BOTTLE slowly while holding the cork. That works great… but it’s not as stunning as the way sharpshooter Kirsten Joy Weiss opens a bottle of bubbly.
A former competitive smallbore rifle shooter, ace trigger-puller Kirsten Joy Weiss tried a special New Year’s trick shot a few seasons back. In keeping with the festive New Year’s spirit, Kirsten attempted to shoot the cork off a champagne bottle. After a few unsuccessful tries, she managed to hit the cork with at least two shots. But alas the cork did not fly. She actually hit the cork, but it did not release. That was surprising…
Undaunted, Kirsten changed her strategy, aiming for the neck of the bottle. This duplicates the process of “sabering” a champagne bottle — a method of liberating the bubbly by slashing off the end of the neck with a blade. Aiming for the neck of the bottle, Kirsten successfully blew off the top of the bottle. (Apparently, when “sabering” it is actually the pressure within the champagne bottle which does most of the work).

We are re-publishing this article at the request of Forum members who found the information very valuable. If you haven’t read this Safety Tip before, take a moment to learn how you can inspect your fired brass to determine if there may be a potential for case separation. A case separation can be dangerous, potentially causing serious injury.
On the respected Riflemans’ Journal blog there was an excellent article about Cartridge Case-Head Separation. In this important article, Journal Editor GS Arizona examined the causes of this serious problem and explained the ways you can inspect your brass to minimize the risk of a case-head separation. As cases get fired multiple times and then resized during reloading, the cases can stretch. Typically, there is a point in the lower section of the case where the case-walls thin out. This is your “danger zone” and you need to watch for tell-tale signs of weakening.
The photo below shows a case sectioned so that you can see where the case wall becomes thinner near the web. You can see a little arrow into the soot inside the case pointing to the thinned area. This case hadn’t split yet, but it most likely would do so after one or two more firings.
Paper Clip Hack for Detecting Problems
The article provided a great, easy tip for detecting potential problems. You can use a bent paper clip to detect potential case wall problems. Slide the paper clip inside your case to check for thin spots. GS Arizona explains: “This simple little tool (bent paper clip) will let you check the inside of cases before you reload them. The thin spot will be immediately apparent as you run the clip up the inside of the case. If you’re seeing a shiny line on the outside and the clip is really hitting a thin spot inside, it’s time to retire the case. If you do this every time you reload, on at least 15% of your cases, you’ll develop a good feel for what the thin spot feels like and how it gets worse as the case is reloaded more times. And if you’re loading the night before a match and feel pressured for time — don’t skip this step!”

The Civilian Marksmanship Program (CMP) invites young men and women shooters to apply for CMP scholarships for the 2020-2021 school year. The CMP offers $1,000 one-year scholarships to current high school seniors. Since 2005, CMP has awarded over $1 million in scholarship grants. Last year, the CMP awarded over $160,000 in scholarship money. Winning scholarship recipients, in their senior year of high school, came from JROTC schools, 4-H groups, and other shooting clubs.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
