Close-up view of a sectioned case. This one here was “fixin’ to pop”, observed Glen Zediker.
Here are highlights from an article Glen Zediker wrote for the Midsouth Blog. In that article Glen, who sadly passed away in 2020, focused on cartridge brass. Glen identified the most common failures that appear with brass that has been shot multiple times, or which has been fired at excessive pressures. Glen explained some simple ways to check your cartridge brass to detect “early warning signs” of case failure, particularly case head separation, which can be very dangerous.
How Cases Degrade with Multiple Firings By Glen Zediker
This article explains when, and then how, to check after the progress of changes commencing with the firing on a new case. It’s the “progress of degeneration,” in a way of looking at it because the concern is getting a handle on when enough change in the brass has come about to require attention. Or abandonment. As said then, for me that’s 4 firings. That, as said last time, is when I might see changes that need attention. Also as said, that figure didn’t come out of a hat, but from my own notes in running my competition NRA High Power Rifle loads. [Editor’s Note: With Lapua brass, using moderate loads, in bolt-action rifles, we typically get about 10 good (match-worthy) firings. But if you anneal your Lapua brass, and run modest pressures, Lapua brass can perform well for 20 or more load cycles.]
The areas most affected are the case neck and case head area. Case neck walls get thicker [but] the case head area body walls get thinner. Primer pockets get shallower and larger diameter.
This case shows a cracked neck AND a crack (separation) above the case head. Zediker says it is “rare to see one case with both of the most common failures. [This case] was attacked by an M14.”
Case Head — Causes of Separation and Cracking
When a case is under pressure during firing, the brass, like water, flows where it can, where it’s more free to move. Of course, the chamber steel limits the amount it can expand. The case shoulder blows fully forward and the case base is slammed back against the bolt face. There is, therefore and in effect, a tug on both ends — it gets stretched. The shoulder area is relatively free to expand to conform to the chamber, but the other end, the case head area, is not. Since that’s the area of the case with the thickest walls, it doesn’t expand “out” much at all. What it does is stretch. The “case head area,” as I refer to it here, is the portion of the case above the web, which is just above the taper that leads in to the extractor groove. The “area” extends approximately an eighth-inch up the case body.
Here’s a “pressure ring.” You’ll see this after firing, if you see it. And, if you see it, that case is done. The bright ring indicates excessive stretching, which indicates excessive thinning. If you see a ring circling the case, noticeable because it’s lighter color than the case body, and it’s in this area, I’d say that case is done. And that’s right where a “head separation” occurs. It can crack and also blow slap in two, and that’s the “separation” part of case head separation.

This is a spot to keep close watch on as cases age. It is also the area that is more “protected” by sizing with less case shoulder set-back. That is, pretty much, where the freedom for the stretching movement in this area comes from (the case shoulder creates a gap). If you’re seeing a sign that a head separation [might happen with relatively few firings], chances are the shoulder set-back is excessive, and also… the load pressure level.
Bent Paper Clip Case-Wall Gauge
Editor: 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.” Photo by GS Arizona.
Monitor Primer Pocket Dimensional Changes
Another case-head-area and pressure-related check is the primer pocket. As said, the primer pocket will get larger in diameter and shallower in depth each firing. As with many such things, the questions are “when” and “how much,” and the main thing, “how much?”
If the pocket gets excessively shallow, and that’s judged by a primer that seats fully but isn’t at least a tick below flush with the case base, there could be function issues. There’s a risk of a “slam-fire” with a semi-auto that uses a floating firing pin, and, if there is actual protrusion, that has the same effect as insufficient headspace. A primer pocket uniformer can reset the depth of a shallowed primer pocket to what it should be, but the real test for me is how easily the next primer seats into it. If it’s significantly less resistance, I’ll say that case is done. Shallower can be refurbished. That’s a primary function of a primer pocket uniformer. Larger diameter, though, can’t be fixed. I’ve mentioned in another article or two that, any more at least, my main gauge of load pressure has become how much primer pocket expansion there’s been.
“A bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.”
A few seasons back a good friend ventured to the high country of Colorado to pursue elk. He recently zeroed his rifle in California, at a range just a few hundred feet Above Mean Sea Level (AMSL). He wondered if the higher altitude in Colorado could alter his ballistics. The answer is a definite yes. However the good news is that free ballistics calculators can help you plot reliable drop charts for various shooting locations, high or low.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:
“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps. By contrast, in Raton, NM, located at 6600′ AMSL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.
Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”
As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect. It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet AMSL), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.
Trajectory of Bullet fired at Sea Level
Trajectory of Bullet fired at 20,000 feet
You can do your own experimental calculations using JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.
To learn more about all aspects of Exterior Ballistics, Hornady has a useful discussion of External Ballistics including the effects of altitude and temperature. To dig deeper, Sierra Bullets has a comprehensive Exterior Ballistics Resource Page with multiple sections from the Sierra Manual (4th and 5th Editions), including:
Section 3.0: Exterior Ballistic Effects on Bullet Flight
Section 3.1: Effects of Altitude and Atmospheric Conditions
Section 3.2: Effects of Wind
Section 3.3: Effects of Shooting Uphill or Downhill
Example from Section 3.0: “When a bullet flies through the air, two types of forces act on the bullet to determine its path (trajectory) through the air. The first is gravitational force; the other is aerodynamics. Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag. All the others are very small in comparison when the bullet is spin-stabilized.”
Larry Medler has come up with a smart little invention — a simple, inexpensive Empty Chamber Indicator for rimfire rifles. It is made from a section of plastic “weed-wacker” line and a wooden ball from a hobby shop. Larry says he was inspired by Juniors who used something similar for their 17-Caliber Air Rifles.
How to Make the Empty Chamber Indicator
Construction Method: First, drill a 7/64″ diameter hole all the way through the 1″-diameter wooden ball. Then enlarge half of that 1″-long hole using a 13/64” diameter drill. Next insert an 8″ piece of heavy duty (0.095″ diameter) weed wacker line through the ball, leaving about 2″ on the side with the bigger-diameter hole. Then, with the short end of the line, fold over the last half-inch so the line is doubled-over on itself. Then slide the line into the ball, stuffing the doubled-over section through the 13/64″ (large) hole. Finally, pull the longer end of the line until the doubled-over section is flush with the outside of the ball. This gives you a sturdy line attachment without messy adhesives. When the assembly’s complete, hold the ECI by the tail and dip the ball in yellow paint. If you’re making more than one ECI, you can drill horizontal holes in a spare block of wood and use that as a drying rack.
At a Rimfire Sporter match like this, all shooters must have an Empty Chamber Indicator.
The Empty Chamber Indicator for Smallbore Rifles
Larry explains: “At all Highpower rifle matches, silhouette matches, and other shooting events I have attended, Open Bore Indicators (OBI), or what are now called Empty Chamber Indicators (ECI) have been mandatory. The NRA’s yellow ECI for Highpower rifles is easy to use and has been well-received by the shooters. However, I had not seen a truly workable ECI for 22 rimfire rifles — until I visited Michigan’s Washtenaw Sportsman’s Club where I saw juniors using ECIs for their 17 Caliber Air Rifles. Someone at the club made the empty chamber indicators by attaching an 8″ piece of weed wacker line to a 1″-diameter wooden ball, painted bright yellow. I now make similar ECIs for the 22 rimfire silhouette matches I run.”

Other Good Books from Gun Digest Media
Gun Digest Media produces numerous other quality books for rifle, pistol, and shotgun owners. Here are four books we recommend. These are offered in both paperback and eBook versions:
Do you use bushings to size your case-necks? Are you assuming that your bushings are actually round on the inside, with a hole that’s centered-up properly? Well you may be in for an unpleasant surprise, based on what our friend Jim de Kort recently discovered. Jim was concerned about the run-out on his brass. His cases went into his bushing-equipped FL die pretty straight, but came out of the die with up to .004″ run-out. “What gives?”, Jim wondered. “Could the problem be the bushings themselves?”
To answer that question, Jim decided to examine his bushings. Using an Accuracy One Wheel-drive concentricity gauge, Jim checked out some of his neck bushings. What he discovered may surprise you…
Neck Bushing Flaws Revealed
Trust no one… — Jim de Kort
Jim writes: “I measured the concentricity of my 6BR rounds today. I noticed they went into the neck-bushing equipped full-length sizing die with less than .001″ deviation but came out with .003-.004″. The culprit, it appears, was the bushing itself. Without it the cases stayed within .0005″ to .001″ deviation, so something was happening with the bushing.
One bushing had .00025″ deviation on the outside, yet almost .003″ on the inside, so it is crooked. But even when using a bushing that is within .001″ I still get .003″ runout after sizing. I repeated the same procedure for my 6×47 and got the same results. When using the bushing, concentricity suffers a lot.”
Before we bash the bushing-makers, we must acknowledge that many different things can contribute to excessive run-out and/or mis-alignment of case-necks. We don’t have all the answers here, and Jim would be the first to say that some mysteries remain. Still, these are interesting results that give all precision hand-loaders something to think about.
Jim Borden of Borden Accuracy also offers this tip: “Check the trueness of the face of the die cap. That has more to do with trueness than the bushing. Also check perpendicularity of hole in bushing to top surface. When I was making dies, the cap was made by threading and facing the threaded tenon in same setup.”
Editor’s Comment: Many people have great results with neck-bushing dies, but Jim isn’t the only fellow who has seen some very odd results. I personally employ honed, non-bushing dies for many of my chamberings. These non-bushing dies (with the necks honed for .002-.003″ neck tension) produce extremely straight ammo, with run-out consistently under .0015″.

Product Review by F-Class John
Case preparation is critical for precision reloading. One must trim cases, debur/chamfer case mouths, clean necks, spruce up primer pockets and do other important tasks. Complete case prep can involve many separate processes, each requiring its own tools. With each of those tools comes additional cost as well as the need for more storage and bench space. To make case prep easier, faster, and more convenient Lyman created the Case Prep Xpress (#ad). The Case Prep Xpress, introduced a few years back, combines up to five prep stages into one well-built, stable, versatile unit. Watch this video to see the machine in action:
The Case Prep Xpress features five (5) independently-turning spindles all with the common 8/32 thread. This allows you to attach multiple tools supplied with the unit PLUS many other screw-on prep tools. For our testing we started out using a variety of the 12 included tools and found they cover the majority of case prep tasks. Lyman supplies deburr and chamfer tools, pocket uniformers, reamers and cleaners, as well as an assortment of neck brushes.
The deburr and chamfer tools worked really well, creating beautiful bevels all while leaving a nice flat edge across the top of the neck which is critical for accuracy and brass life. We found the primer pocket cleaning tool did a good job, but for truly clean pockets we recommend using the primer pocket uniforming tool, which very efficiently removes even hard residues.
The benefit of having interchangeable heads is that you can add your own accessories. We like to use a bore brush with bronze wool wrapped around it for use inside our necks. This worked perfectly once we screwed it in. In fact, we couldn’t think of any 8/32-threaded accessory that wouldn’t work well on this machine. Another great design feature is how all the accessories are oriented straight up. This allows for perfect visual alignment of your cases onto the tools which is critical — especially when performing cutting operations such as primer pocket uniforming.
Along with the five power stations there are six female-threaded storage spots on the sides where tools can be placed to ensure they don’t get lost. We like this feature since there will be more than five accessories you want to use and having them easily available is a great feature. You can keep 11 tools right on the machine (5 on top, 6 on the sides). That way you don’t have to dig through storage bins.
The Case Prep Xpress has a removable front bin to hold brass shavings, and there are two circular trays on either side of the bin. In front is a long tray that holds the provided brush. This makes it relatively easy to clean off brass shavings and other debris from case prep processes.
SUMMARY — Versatile Case Prep Xpress Is A Good Value
For the money, Lyman’s Case Prep Xpress is tough to beat. It performs multiple tasks well while being stable and easy-to-use. Yes there are some multi-spindle prep centers that offer variable or fast/slow RPM spindles while the Lyman’s spindles are all fixed RPM. (See, e.g. the RCBS Brass Boss). However those other systems don’t include all the convenient on-board storage of the Case Prep Xpress, and are typically more expensive. The Lyman Case Prep Xpress typically sells for about $199-$209 “street price”. It’s currently on sale for $174.99 on Amazon (#ad). This makes the Lyman Case Prep Xpress a good value — it offers great versatility while saving space and saving money compared to buying five or more separate, powered tools.

This photograph and all images for this story are by Bill White, aka “CT10Ring” in our Forum.
AccurateShooter Forum member Bill White (aka “CT10Ring”) is not your typical member. For 37 years, Bill worked in NYC as a studio photographer specializing in still lifes and products. A neighbor visiting Bill’s home in Connecticut with a .270 Sako inspired Bill to revive his interest (obsession?) with shooting after a 25-year drought. And he owns a few Sakos now! With his gun hobby renewed, for many years Bill drove to the Western USA to shoot long range steel and a LOT of prairie dogs in season. He loved the life of the varminter, so it made sense for him to move West after retiring. He choose Idaho as his new home.
From his Idaho base, Bill enjoys long-range target shooting. But his favorite gun pastime has been varmint hunting in nearby states — the Dakotas, Montana, and Wyoming. Bill found prairie dog shooting rewarding and mapped out a western circuit route of ranches and National Grasslands in SD, ND, MT, and WY. Every year he loads up his truck and hits the road, often doing a grand circle route, visiting prairie dog havens in multiple states. In this article we feature photos from Bill’s annual “grand circle” varmint safari.
For his many cartridge types, Bill learned about reloading methods, loads, and vendors (and more) primarily from AccurateShooter.com. We start today’s story with the biggest caliber rifle he shoots regularly, his 6.5-284 Winchester. Bill favors this rig for his long-range steel shooting. He also uses it for prairie dog shooting, but only “sparingly”, because he wants to preserve barrel life, and he has many other dedicated varmint rigs.
6.5-284 for Long Range Steel Targets (and Sometimes Varmints)
In his home state of Idaho, Bill likes to shoot steel at long range. For distance work, Bill favors his McMillan-stocked 6.5-284 Win. This rifle was crafted in 2012 by Bob Green of York, PA, using a 1:8″-twist 28″ Krieger HV barrel (.298″ neck). The trued Rem 700 action was purchased from Long Rifles in Sturgis, SD. Bill did the Cerakote and bedded the action. For his 6.5-284, Bill loads 139gr Lapua Scenars, H4831sc powder and BR2 primers. He shoots both steel and varmints with this rifle, but the varmint work is limited because the 6.5-284 cartridge tends to be a barrel burner. The photo below from an Idaho range was taken near a 500-yard target, looking back at the firing line.
In the Varmint Fields — Traveling Light
Once situated, Bill (shown above) prefers to walk to Prairie Dog towns with a shooting mat, two bipod-equipped rifles slung up, rear bag, water, and his trusty Leica 10X42 GeoVid binoculars. While he has used a portable bench, he prefers to shoot from bipod, firing down from a mound if possible. This allows him to set up a line-of-fire that minimizes cross-wind effects. Bill notes: “While I often start early, end-of-day shooting has worked worked well for me. A setting sun shows targets better, the wind is usually down, and it’s not so hot. Often you can spot the bullet trace and that’s fun.”
Eight Great Varmint Cartridge Types — .204, .224, .243 Calibers
Here is one of Bill Reid’s 6mmBR (6BR) rigs. Like his Sako 6 PPC, this is exceptionally accurate.
Bill has a large rifle collection, most of which see duty in the varmint fields of Montana, North Dakota, South Dakota, and Wyoming. Here are his key “take-aways” for his eight favorite varmint chamberings: .204 Ruger, .223 Rem, .22-250, .22 BR, .22-243, 6 PPC, 6mmBR, and 6-6.5×47 Lapua (aka 6×47).
.204 Ruger — This delivers great velocity with the little .20-caliber bullets, with mild recoil. The .204 Ruger easily reaches out to 400 yards, but heavier winds do move the tiny bullet around. Tremendous splat factor under 250 yards. I use Sierra 39gr bullets with IMR 8208 XBR in a Sako 75. Even now, .204 Ruger ammo is relatively easy to find.
.223 Remington — Probably the most popular centerfire rifle round in the USA, the .223 Rem offers inexpensive brass, and is a great choice for AR-15 owners. If you run short on ammo, you can find it nearly everywhere. I often bring one AR-15 and one .223 Rem bolt gun on varmint safaris. My Rem 700 5R 1:9″-twist barrel likes 53gr V-Max bullets.
.22 BR — My .22 BR is my first choice for most prairie dog missions. Accuracy is superb with necked-down 6mmBR Lapua brass — quarter-MOA and blazing fast. With the right twist rate, this chambering can shoot anything from 40gr FB bullets to 80gr VLDs. Load development is easy. Below is my .22 BR ammo for another varmint trip. I use 55gr Sierra BlitzKings with Varget in my 1:12″-twist Shilen-barreled rifle. 60gr Bergers are very accurate with a fairly flat trajectory for useful distances.
.22-250 Rem — A classic varmint cartridge, the .22-250 with 50gr V-Maxs delivers spectacular hits. If three P-Dogs happen to be lined up, I’ve witnessed one .22-250 shot take ‘em all out with a triple hit. I currently have five .22-250-chambered rifles: 3 Sako 75s, one Rem 700, and a single shot Nesika that shoots tiny groups. I favor the very deadly Berger 52gr Varmint HP. Making a custom .22-250? With a 1:8″-twist barrel you can use the full weight range of .22-cal bullets, while spinning the lighter bullets fast for “red mist” effect. Remember this cartridge can be a barrel burner. Don’t shoot too many rounds too quickly.
.22-243 Win — This wildcat is even more potent than the .22-250, delivering devastating results on P-Dogs. Run a .243 Win case slowly through a full-length .22-243 die, with plenty of lube to form the brass. I start with Lapua .243 Win brass. There can be some issues necking-down the brass. Watch for donuts forming at the neck-shoulder junction. I bought my .22-243 rifle not sure how it would perform. But now I love shooting it. My .22-243 delivers half-MOA groups with 41.0 grains RL-22 and Hornady 75gr Amax bullets. With those 75-grainers, it’s great in the wind and good to 600 yards easily.
6 PPC — You may consider the 6 PPC a benchrest competition cartridge only, requiring fire-forming. However I have an original Sako 75 single-shot 6 PPC rifle that I load with Sako-headstamp 6 PPC brass (see below) so no fire-forming is required. This Sako 75 came with a test target that measured 0.113″! With my 6 PPC Sako, I found that 58gr V-Maxs, pushed by Vihtavuori N133, are potent out to 300 yards.
6mmBR — The 6mmBR Norma (6BR) offers a nearly unbeatable combination of accuracy, efficiency, and tunability. With the 6BR and a fast twist barrel, you can shoot everything from 40gr flat-base bullets to the latest 105-110gr match bullets. I load Lapua brass, Vihtavuori N135, and Hornady 58, 65, and 75gr bullets for my Krieger 1:14″-twist HV barrel. While this cartridge is capable of long-range accuracy, I usually limit my 6BR shots to 350-400 yards.
6-6.5×47 Lapua — In this story’s lead photo is my 6-6.5×47 Lapua varmint rifle, with Surgeon action and Manners stock. I Cerakoted the barreled action and then bedded the action. Shown below is 6-6.5×47 ammo I loaded for recent testing. Note how I separated different bullets and powder loads into multiple, labeled bags. Hodgdon H4350 is a great choice for this cartridge — 39 grains H4350 with 105gr Amax was the winner here, but 88gr Bergers also shot well. This cartridge has tremendous “critter dismantling” abilities out to 600-700 yards.
Six Tips for Novice Long Range Varmint Hunters
1. Take twice as much ammo you think you may need. The fields could be particularly rich, or, because of wind or other variables, you may have far more misses than expected.
2. When possible, set up with the wind at your back (or, alternatively, directly ahead). This will minimize the effect of cross-winds. Set up a stake with a ribbon to show wind direction.
3. Bring at least two rifles. Ideally one would be a low-recoil rifle with cheaper components for the closer shots. Then bring a rifle with higher-BC bullets for longer shots where wind is a bigger factor.
4. Check the weather before you head out. Prairie dogs like sunshine and calm conditions. If a cloudy, very blustery day is predicted, considering staying in town and cleaning the rifles.
5. Bring plenty of water on a trip. An adult male should be drinking at least 64 ounces of water (or other liquid) every day — more if it’s very hot or you are sweating a lot.
6. Preferably always hunt with a companion. If you do go out solo, have a Garmin inReach SatComm/GPS for emergencies if there is no cell coverage in your location.
Veteran Varmint Hunter Shares his Secrets
Where to Find Abundant Prairie Dogs — Generally, black-tailed P-Dogs are found in the Western high desert, in the same states/areas where cattle are raised. You’ll find good hunting in Montana, North and South Dakota, Colorado, and Wyoming. There are good hunting grounds on private ranches, BLM tracts, and U.S. National Grasslands. To find specific locations, I’d suggest calling the USFS, BLM, and State Fish & Game. Some have lists of ranches that allow P-Dog shooting. Give the agencies a call before your trip and then check in with ranchers. IMPORTANT: You need a current hunting license in some states.
How to Connect with Ranch Owners– A good varmint adventure can begin with a local connection. Stop into the local Ag/feed store and the town breakfast spot. I bet you’ll find some retired ranchers having coffee together who may direct you to a place that needs rodents thinned out. Let’s say you’re in Roundup, Montana. Stop by a local store and ask what ranchers allow PD shooting. Keep in mind that ranchers may be wary of allowing a total stranger to sling lead on their place. Show respect and if you had a good experience, send a thank-you note. A guided shoot is worth considering — the outfitter will know where the P-Dogs are and he has arrangements with landowners. He may even supply benches. I’ve taken two guided trips, with excellent results, one near Sturgis, SD, and the other on Sioux tribal land near Rosebud, SD.
Getting Set Up — I start early in the a.m. to mitigate mirage. Plus there is usually less wind at that hour. I prefer to drive to within half mile or so of a PD town, then walk and shoot prone. Most shooters like to set up a rotating bench on a knoll. This is a tried-and-true way to shoot long distances accurately, especially if you are on top of a hill and can shoot 360 degrees. I once shot from a rotating bench, but I prefer walking now. Some country is quite stunning and that’s half the fun — being out in nature. But yes there are negatives to shooting prone — ground hazards and tall grass can impede your vision.
Equipment for a Serious P-Dog Safari — In the field, I normally carry two rifles with Harris 9-13″ bipods, backpack, a rolled-up shooting mat, at least two liters of water, food, ammo, two rear bags, and binoculars. A good laser rangefinder comes in handy. If you prefer shooting from a bench you may want to have a front rest and a spotting scope. Many guys will shoot prone from the bed of a truck. That gets you off the ground without the need to haul around a heavy bench. But some locations restrict vehicles. Before a P-Dog trip, I make a detailed pack list and check off as I load my truck and camper. I would suggest bringing waterproof rubber or muck boots. June in South Dakota can be cold and wet, and the mud there is not to be believed. Don’t attempt to drive off road in it!
It’s good insurance to bring an extra 5 gallons of fuel for your vehicle in a jerry can and 2 gallons of H20. There may be NO shade for miles and dehydration is a real possibility. Having a couple heavy duty tarps will provide a sun shade and cover your gear in a rainstorm. I bring a 16″ X 20″ plywood target backer, a stand, and paper targets. This allows me to check zero on each rifle before I head out to the Dog Town.

Taking Photos on Shooting Adventures
Bill knows a thing or two about taking pictures, having been a professional photographer in NYC for many decades. He uses modern digital cameras for both his outdoor and indoor work. Most photos in this story were taken with a Canon EOS 5DSR MKIV. We asked Bill for some tips on taking good photos. Here are his FIVE Top Tips for Photography:
1. Take photos in the early a.m. and later p.m. when the light has definition. Mid-day results will not be so nice.
2. Use the highest-resolution camera available that fits your budget. Yes lens quality, focus, and exposure controls make a big difference.
3. When feasible, shoot using a manual setting with the lens wide open (for shallow focus). Set the focus on the most important object/subject in the frame.
4. Photoshop is useful, especially when RAW images need to be corrected to show the scene more faithfully, or enhance it.
5. After you take a picture, before you post it on social media, learn to crop the image, straighten the horizon, and do other basic fixes. This can make a big difference.
This custom war wagon hauls varmint hunters around the Longmeadow Game Resort in Colorado.
May Day, May 1st, is just five days away, so we are well into springtime (spring officially started on March 20, 2026, the Vernal Equinox). For many shooters, Spring is a great season to head out to the varmint fields. Here are six items that can help ensure successful spring varmint adventures.
Six Great Products for Varmint Shooters
1. Riflekühl In-Action Fan Barrel Cooler
In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. The Riflekühl by Magnetospeed is a simpler, less costly, and much handier solution. Busy varmint shooters may expend hundreds of rounds in a day. That’s tough on barrels. One way to extend your round count is to use the MagnetoSpeed Riflekühl barrel cooler.
This barrel cooler is designed to get barrel temperatures down to intended operating levels quickly. The turbocharger-inspired impeller is engineered to produce great airflow in a small package. Powered by a single CR123A Lithium battery (included), ambient air is forced through the extendable nozzle down the bore of the rifle. This is pretty efficient and can typically cool a barrel in under 8 minutes. The Riflekühl doubles as a chamber flag and features an exclusive built-in air filter to prevent dust and dirt from being blown into your rifle.
2. Uncle Bud’s Bulls Bag Sandbag
On most varmint hunts we spend most of the time shooting from a portable bench with a pedestal-type rest (we like the SEB Mini). But it’s nice having a big, heavy X-Type sandbag rig also. These four-chamber designs, such as the Uncle Bud’s Bulls Bag, allow shooting from a truck hood or any flat surface. Some rifles with narrow fore-ends really benefit from the firm “hug” provided by these “butterfly” style sandbags. We like the 15″ Uncle Bud’s Bulls Bag, currently $80.00 at BullsBag.com (khaki/suede). Durable and well-made, it will provide years of service. There is also a 10″ version that is easier to carry, starting at $62.00. Forum member Stoner24mkiv likes a Bulls Bag for shooting from a vehicle. He also suggests: “[take] an adjustable bipod if you are going to do any walking. Have a fanny pack or backpack for extra ammo, water, bore-snake, etc. when you go on your walkabouts. Bring a Boonie hat for blocking the sun, sun glasses, sunscreen. High leather boots.”
3. Burris Scope with Built-In Laser Rangefinder
The Burris Eliminator is an impressive piece of electro-optical technology. With a push of a button, a built-in laser rangefinder senses the distance to your target and the Eliminator’s microprocessor instantly calculates the required hold-over based on your load’s ballistics. The calculated aiming point is then displayed in the reticle with an illuminated red dot on the vertical cross-hair. Just put the red dot on the target and make the shot. Easy as that. If you are working a large prairie dog field and constantly moving near to far and back again, this scope is really handy. We’ve used the Eliminator III out to 500 yards on small steel targets and it worked flawlessly.
Right now you can get the 5-20x50mm Burris Eliminator 5 model for $999.99 on Amazon (#ad). Or you can still get the older 4-16x50mm Burris Eliminator 3 model at some dealers. Note: the Eliminator 3 and 5 have been replaced by the compact 4-20x52mm Eliminator 6, but that newer model has a $2999.99 MSRP ($1874.99 at MidwayUSA on sale). The Eliminator 5 is way less expensive than the newer Model 6 (even with the sale discount).
4. Hornady 17 HMR V-Max Loaded Ammo
For those distant prairie dog shots, you’ll want a centerfire round such as a 22 BR or 22-250. However, for closer work, or for smaller varmints such as ground squirrels, the 17 HMR is hard to beat. There are many good factory rifles chambered for the 17 HMR, such as the Savage A17 (shown below). Right now Hornady 17 HMR ammo is on sale at FastAmmo.com for $10.90/50 ($0.22 per round). That’s a good deal. This same ammo sells elsewhere for up to $18.00 per 50-round box. NOTE: Hornady also offers 17 HMR ammo with 20gr XTP hollow-point bullets ($12.25/50 at FastAmmo.com). Both types work well.
5. Stick-On Temp Strips Monitor Barrel Heat
You never want your barrel to get too hot. Accuracy suffers when barrels over-heat, and excessive heat is not good for barrel life. So how do you monitor your barrel’s temperature? You can check if the barrel is “warm to the touch” — but that method is not particularly precise. There is a better way — using temperature-sensitive strips. McMaster.com (an industrial supply house) offers stick-on temp strips with values from 86° F to 140° F. A pack of ten (10) of these strips (item 59535K13) costs $12.11 — so figure it’ll cost you about $1.21 per barrel for strips. That’s cheap insurance for your precious barrels. For best barrel life, try to stay under 120 degrees F.
6. Low-Fouling Power for High-Volume Varmint Loads
For high-shot-count varmint safaris, you want a clean-burning powder that minimizes barrel fouling. While there are many great powders for the .223 Rem, we like Hodgdon CFE 223 for high-volume varmint loads. This powder really seems to keep barrels cleaner. Originally developed for U.S. rapid-fire military systems, CFE 223 incorporates a proprietary chemistry named “Copper Fouling Eraser”. Based on tests with extended shot strings, Hodgdon claims that, by using CFE™223 varmint hunters, match shooters, and AR shooters can maintain accuracy for longer periods, with less barrel-cleaning time.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
