Spring Groundhog Hunting — Fun and Challenging
Springtime is the right time for groundhog hunting in the Northeast USA. Groundhog hunting is both fun and challenging. In today’s Saturday Showcase, we feature three videos showing successful groundhog hunts. Then there is a video about checking your equipment and verifying your varmint rifle zero.
We’ve even included a good video offering cooking tips for groundhog/woodchuck.* Yes groundhog meat can be quite savory — used in stews, sandwiches, or tacos. Last but not least we’ve included a section on groundhog shooting matches. These are fun matches with paper and/or steel groundhog targets.
Groundhog Hunt Report — Successful Stalk and Shoot
Here’s a great Realtree.com video showing successful groundhog hunts. This covers the process of spotting and tracking groundhogs on farmlands. Woodchucks are sensitive creatures that get easily spooked. This video shows that groundhog hunters need patience and skill, plus an accurate rifle.
Groundhog Hunting on the Family Farm with .17 HMR
In this video, the host employs his CZ 457 rifle chambered in .17 HMR to hunt groundhogs on his farm. The video provides a hunter’s POV with excellent Scope-Cam footage. This young shooter has 280 videos on his popular Blocketh Outdoors Channel including videos showing how to stalk groundhogs successfully. These critters go to ground quickly if they see or hear the hunter. NOTE: The lead photo for this Saturday Showcase comes from another Blocketh Outdoors groundhog video.
Groundhog Killshot Compilation Video
Here’s a classic “killshot” video showing multiple hits on groundhogs. If you want to see how a well-aimed varmint bullet can flip, spin, and elevate a groundhog, this video will keep you entertained. While we like explosive hits on prairie dogs, it may be better to use a solid, non-expanding bullet if you plan to harvest the groundhog (aka woodchuck) meat.
Groundhog Hunting — Importance of Confirming Your Zero
This AR15 Hunter channel video covers getting ready for spring groundhog season. This is a helpful video that shows how to confirm your zero on your varmint rifle. If you have an AR-platform Modern Sporting Rifle, this video is worth watching.
If you don’t have groundhogs in your part of the USA, don’t fret. You can still have fun hunting smaller varmints such as ground squirrels and Prairie Dogs. Here’s a good video covering P-dog hunts with a suppressed .223 Rem AR. The video covers recommended equipment including bipod, tripod, and optics.
Groundhog Matches — Fun Shooting at Paper and Steel ‘Hogs
Along with actual groundhog hunting, many shooters like to shoot paper and/or steel groundhogs in club groundhog competitions. These are fun matches that you can shoot with a variety of rifles. Our first choice would be a 22 BR for ranges out to 450 yards or a 6 BRA if targets are farther out. One popular match in the Northeast is the St. Thomas Ground hog shoot in Pennsylvania (see below).
At clubs across the country, varmint fun shoots (also known as “groundhog matches”) are becoming more popular every year. In these matches, usually shot from the bench, you engage paper targets, clay pigeons, steel “critter” silhouettes, or some combination of paper and reactive targets. Shooters like these matches because you can shoot a wide variety of rifles, you don’t have to spend a fortune to be competitive, and there is fun for the whole family. Rules are inclusive — you won’t be turned away because your rifle is two ounces overweight. A large percentage of the match fees usually go back to shooters in the form of cash prizes. And the level of camaraderie is high.
St. Thomas Groundhog Shoot, Report by Jonathan Trivette
Nestled at the base of a mountain in south-central Pennsylvania is the St. Thomas Sportsmen’s Association. On a cool Saturday morning you’ll find some of the area’s best shooters at the monthly Groundhog Match. The match attracts shooters from Virginia, Maryland, West Virginia, and of course Pennsylvania.
It may not be the longest-yardage match in the area, but it can be the one of the toughest. The range is sloped up the mountain a little so the winds can be very tricky. Often times the three wind flags at 200, 300, and 400 yards will all be blowing in different directions.
* “Groundhog” and “Woodchuck” are simply two different names for the same animal. Both terms have been used in the English language since the 1600s. In many places, the terms are used interchangeably, but “groundhog” is now increasingly more common in the USA.
Do you know what the inside of a rifle chamber (and throat zone) really looks like? Do you understand the concept of headspace and why it’s important? If not, you should read the Brownells GunTech article Gauging Success — Minimum Headspace and Maximum COL. This article explains the basics of headspace and shows how to measure headspace (and length to lands) in your barrels with precision. The article also explains how to adjust your full-length sizing dies to “bump the shoulder” as needed.
Why is headspace important? The article explains: “Controlling headspace and setting proper C.O.L. also represent improved safety and reduced cost of handloading. Excessive headspace can cause case head separation and gases in excess of 60,000 PSI escaping from a rifle’s chamber. Too little headspace can result in a chamber forced bullet crimp and a bullet that becomes an obstruction more than a properly secured projectile. Excessive C.O.L. can result in a rifling-bound bullet, a condition that could result in spikes of excessive pressure.”
[Editor’s NOTE: It is common for competitive benchrest shooters to seat bullets into the rifling. This can be done safely if you reduce your loads accordingly. With some bullets we often see best accuracy .010″ (or more) into the lands. However, this can generate more pressure than the same bullet seated .010″ away from initial lands contact. As with all reloading, start low and work up gradually.]
Headspace is a measurement from the bolt-face to a point in the chamber. This point of measurement will vary based on the type of cartridge. Improper headspace, either excessive or (conversely) under SAAMI specifications, can cause a variety of problems, many serious.
How is headspace specified? Most cartridges used within the United States are defined within ANSI/SAAMI Z299.3-4. Brownells explains: “In the case of the .243 Winchester, as an example, there are pressure specifications, cartridge drawings and, as pictured above, chamber drawings. Armed with a chamber drawing, each manufacturer producing a firearm for the .243 Winchester knows the proper standard dimension to cut chambers and set headspace. Notice there are two headspace reference dimensions for the chamber. The upper is a place in the chamber where the shoulder is .400″ in diameter; the “datum” or “basic” line. The lower is the 1.630″~1.640″ minimum – maximum dimension from the breech face (bolt face) to that point in the chamber that measures .400″.”
The actual headspace of any firearm is the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.
Finding Cartridge Length to Lands with OAL Gauge
Using a comparator on a set of calipers, you can quickly determine cartridge base-to-ogive length. This is the measurement from the base of the case to the forward-most full diameter section of the bullet, which is for convenience called the ogive. (Technically, the “ogive” is the full curve from bullet tip back to full-diameter ring). Shown here, that ogive is 0.243″ diameter.
The next step is using a modified (threaded) case with a Hornady OAL tool to determine Length-to-Lands (LTL) in your rifle’s chamber. During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are 5 tips that will help you get repeatable and reliable LTL measurements:
1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the OAL Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.
SUMMARY: Powder can have a very long shelf life. You need to watch for changes in smell and color. A reddish tinge, almost like rust on the powder, is a bad sign, as is a foul odor, not to be confused with a normal chemical smell. Either of these signs indicate it is time to dispose of your powder by means other than shooting.
Ever wondered about the stability of the propellants in your reloading room? There are some important things you should know about powder storage, to ensure consistent powder performance and safety. Western Powders (which has been acquired by Hodgdon) published an informative Q & A series entitled Dear Labby: Questions for our Ballistics Lab. Here are some excerpts that pertain to powder storage and shelf life. Worried that your powder may be too old? Western’s experts explain how to check your propellants for warning signs.
Proper Powder Storage
Q: I live in southern Arizona where it is very hot. I am told powders will become unstable if stored in an area not air-conditioned. My wife says no powder or primers in the house. Can powder be stored in a refrigerator? What about using a fireproof safe? I would appreciate your ideas. — M.C.
Lab Answer: SAAMI guidelines are pretty clear on issues of storage. They recommend storing smokeless powder in containers that will not allow pressure to build if the powder is ignited — ruling out gun safes and refrigerators.
In their original containers, the lifespan of smokeless powders is quite long, even in hot, arid climates. In fact the lifespan is typically longer than the average handloader would need to store them. Stored safely in a garage or outbuilding, your powder should last years. If you see the powder developing a reddish tint, or giving off a foul odor, it is time to discard it.
Clumps in Powder Container
Q: I ordered some of your Accurate 1680 powder back about in December. I just now opened it … and it is full of clumps. My knowledge tells me that means moisture. Am I wrong? I just now broke the seal and it has been stored in a ammo can with desiccant packs around it and a dehumidifier running 14-16 hours a day. I can’t imagine this being my fault, if this does indicate moisture. I don’t know if the pink part on the label is suppose to be red or not, but it is definitely pink, so if it was red I am wondering if I was shipped an old container? I hope that this isn’t bad and I am stuck with it…
Lab Answer: All powder contains a certain amount of moisture. When the powder is stored or during shipping, it can go through temperature cycles. During the cycling, the moisture can be pulled to the surface and cause clumping. Clumping can also be caused by static electricity if too dry or the powder has limited graphite content. You can break up the clumps before metering and they shouldn’t be a problem. This will not affect the powder performance, so your product is fine. Accurate 1680 labels are designed in Pink. As a side note, specification for testing powder is at 70° F and 60% humidity.
Shelf Life and Packaging Dates
Q: Does powder ever get to old to use and what identifying marks does your company put on the canister for when it is made, You have helped me out a while ago when I asked about keeping my cowboy shooting under 950 fps and it works great less stress on the hand and the recoil is very minimum. — R.B.
Lab Answer: On one pound bottles, the number is on the corner in a silver box. If the powder was poured today, it would read 012815 followed by a lot number. The whole number would look something like 012815749. Eight pound bottles have a sticker on the bottom with an obvious date code. The lot number appears above the date.
One of our Forum members complained that he wasn’t able to set his primers flush to the rim. He tried a variety of primer tools, yet no matter what he used, the primers still didn’t seat deep enough. He measured his primers, and they were the right thickness, but it seemed like his primer pockets just weren’t deep enough. He was mystified as to the cause of the problem.
Well, our friend Boyd Allen diagnosed the problem. It was the decapping rod. If the rod is adjusted too low (screwed in too far), the base of the full-diameter rod shaft (just above the pin) will contact the inside of the case. That shaft is steel whereas your case is brass, a softer, weaker metal. So, when you run the case up into the die, the shaft can actually stretch the base of the primer pocket outward. Most presses have enough leverage to do this. If you bell the base of the primer pocket outwards, you’ve essentially ruined your case, and there is no way a primer can seat correctly.
The fix is simple. Just make sure to adjust the decapping rod so that the base of the rod shaft does NOT bottom out on the inside of the case. The pin only needs to extend through the flash hole far enough to knock the primer out. The photo shows a Lyman Universal decapping die. But the same thing can happen with any die that has a decapping rod, such as bushing neck-sizing dies, and full-length sizing dies.
Whenever you use a die with a decapping pin for the first time, OR when you move the die to a different press, make sure to check the decapping rod length. And it’s a good idea, with full-length sizing dies, to always re-check the height setting when changing presses.
There are a variety of decapping dies currently on the market, with models available from LEE, Lyman, Hornady, RCBS, Redding, and Sinclair Int’l.
LEE Universal Decapping Die Costs Just $11.49
Speaking of decapping tools, Midsouth Shooters Supply sells the LEE Universal Decapping Die for just $11.99 (item 006-90292), a very good deal. There are many situations when you may want to remove primers from fired brass as a separate operation (prior to case sizing). For example, if your rifle brass is dirty, you may want to de-cap before sizing. Or, if you load on a progressive press, things will run much more smoothly if you decap you brass first, in a separate operation.
Decapping Dies for Cases with Smaller Flashholes
TAKE NOTE: Some Euro Small Flash Holes are spec’d at 1.5mm or 0.059″, and max out at about .062″, so these need a smaller die pin.
The low-cost LEE Universal Decapping Die will work with cartridges from 17 Fireball all the way up to big Magnums. However, NOTE that the decapping pin supplied with this Lee die is TOO LARGE for LAPUA 220 Russian, 6mmBR, 6.5×47, 6.5 Creedmoor, .308 Win (Palma) and Norma 6 PPC flash holes. Because the pin diameter is too large for these brass types, you must either turn down the pin, or decap with a different tool for cases with .059-.062″ flash-holes.
Sinclair Int’l offers a Stainless Decapping Die that comes with BOTH .080 and .060 Pins. The $46.99 die ships with three decapping pins for standard .080″ flash holes, and two pins for .060″ flash holes.
Redding makes a Universal Decapping Die with an optional smaller-diameter decapping rod for the smaller .059-.062″ flash holes found on the BR and PPC cases. The use of this die is explained in the video below:

A new Vortex video series, Cartridge Talks Comparisons, looks at multiple variables along with ballistics gel tests to determine the comparative performance of popular cartridge types. Each Month, Cartridge Talks will examine and test two popular cartridges, comparing their head to head performance. In Episode 1, Vortex Nation™ hosts Mark Boardman and Ryan Muckenhirn pit the 6.5 Creedmoor and .308 Winchester cartridges against each other, examining projectile performance. Mark and Ryan then make conclusions about the applications best suited to each cartridge type.
Cartridge Comparison 14-minute video, Highlighting Ballistic Gel Testing
This first Cartridge Talks Episode pits the 6.5 Creedmoor against the .308 Winchester in a head-to-head, ballistics gel-induced bullet battle. Ballistics (drop/drift), penetration ability, terminal performance and other variables are tested with a variety of tools and tests. Viewers are invited to check out Episode 1, and suggest future cartridge battles in the comments section.
Here is the full 67-minute 6.5 Creedmoor vs. .308 Win Cartridge comparison video:
“With the myriad of cartridges available to the big game hunter, picking which chambering is best for you and your application can be a daunting task,” says Muckenhirn. “In Cartridges Talks, we put our biases on the shelf and put as much scientific process to this as possible. From ‘shootability’ and accessibility, to terminal performance as observed in ballistics gel, Cartridge Talks wades through the numbers and figures with you, loads you up with the pertinent information, and helps you select the ideal cartridge for your next hunt!”
For today’s Saturday at the Movies special, we provide a selection of videos showcasing rifle and pistol cartridge types — from tiny .17 caliber cases to huge 20mm cases. Two of the videos use advance computer animation to provide 3D views of dozens of cartridge types. Then there are some expert commentaries by Jerry Miculek and Ron Spomer discussing the characteristics and performance of various cartridge types. Finally, we provide two videos that discuss rimfire cartridges and show how .22 LR rounds are produced in a modern CCI factory.

Ammo Types and Calibers — Jerry Miculek Explains the Basics
In this video, legendary shooter Jerry Miculek talks about popular types of pistol and rifle ammunition and the various bullet options used for plinking, competition, and self-defense. Jerry, one of the greatest pistol shooters on the planet, provides useful insights on cartridge selection and bullet choices. Jerry notes: “There are a TON of different types of ammunition” so he explains the basics. And Jerry answers common questions such as: “What is the difference between ball and hollow-point bullets?” and “What type of gun takes rimmed cartridge versus rimless?”.
.22 Caliber Rimfire Cartridges — Some Key Facts Revealed
We recommend all .22 rimfire shooters watch this video from Old English Outfitters. It explains some important facts and clarifies some common misconceptions about to .22 caliber ammunition. To learn more about modern .22 LR rimfire ammo, we also recommend the video below, which shows how CCI .22 LR ammunition is manufactured, start to finish.
BONUS Video — How .22 LR Ammunition Is Made
YouTube host 22Plinkster toured the CCI/Speer production facility in Lewiston, Idaho. While touring the plant, 22Plinkster was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching.
This revealing video shows all phases of .22 LR ammo production including cupping, drawing, annealing, washing, drying, head-stamping, priming, powder charging, bullet seating, crimping, waxing, inspection, and final packaging. If you’ve got ten minutes to spare, we really recommend you watch the video from start to finish. You’ll definitely learn some new things about rimfire ammo.
Wouldn’t it be nice to have a print resource that has hundreds of true-size cartridge illustrations, plus technical descriptions of thousands of popular cartridge types? That could be a real time-saver. It’s no wonder this Ammo Encyclopedia book is an Amazon category best-seller.
If you’re a serious shooter, the latest 7th Edition of the Ammo Encyclopedia belongs in your library. This 928-page book by Charles Priore Jr. and Lisa Buening is probably the most comprehensive and up-to-date book in print covering current and classic cartridges and shotshells. The Ammo Encyclopedia is a massive resource work. The 7th Edition, released in October 2022, now boasts 100+ chapters, covering thousands of handgun, rifle, and shotgun cartridges.

Photo 1: Three Near-Equal-Weight 7mm Bullets with Different Shapes
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
This article, from the USAMU Facebook Page, concerns reloading safety. In the relentless quest for more speed and flatter ballistics, some hand-loaders load way too hot, running charges that exceed safe pressure levels. Hint: If you need a mallet to open your bolt, chances are your load is too hot. Stay within safe margins — your equipment will last longer, and you won’t risk an injury caused by over-pressure. In this article, the USAMU explains that you need to account for bullet shape, diameter, and bearing surface when working up a load. Don’t assume that a load which is safe for one bullet will be safe for another even if both bullets are exactly the same weight.
How Bullet Profile and Bearing Surface Affect Pressure Levels
Today, we continue our handloading safety theme, focusing on not inadvertently exceeding the boundaries of known, safe data. Bullet manufacturers’ loading manuals often display three, four, or more similar-weight bullets grouped together with one set of load recipes. The manufacturer has tested these bullets and developed safe data for that group. However, seeing data in this format can tempt loaders — especially new ones — to think that ALL bullets of a given weight and caliber can interchangeably use the same load data. Actually, not so much.
The researchers ensure their data is safe with the bullet yielding the highest pressure. Thus, all others in that group should produce equal or less pressure, and they are safe using this data.
However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. In fact, diameters can occasionally range up to 0.001″ by design. Thus, choosing untested bullets of the same weight and caliber, and using them with data not developed for them can yield excess pressures.
This is only one of the countless reasons not to begin at or very near the highest pressure loads during load development. Always begin at the starting load and look for pressure signs as one increases powder charges.
Bullet Bearing Surface and Pressure
Bullet bearing surface length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In Photo 1, note the differences in the bullets’ appearance. All three are 7 mm, and their maximum weight difference is just five grains. Yet, the traditional round nose, flat base design on the left appears to have much more BSL than the sleeker match bullets. All things being equal, based on appearance, the RN/FB bullet seems likely to reach maximum pressure with significantly less powder than the other two designs.
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284 inch) very near the cannelure. This taper is often seen on similar bullets; it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430″, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!
Some might be tempted to use a bullet ogive comparator (or two) to measure bullets’ true BSL for comparison’s sake. Unfortunately, comparators don’t typically measure maximum bullet diameter and this approach can be deluding.
Note: Due to time constraints, the writer used an approximate, direct measurement approach to assess the bullets’ different BSLs. While fairly repeatable, the results were far from ballistics engineer-grade. Still, they are adequate for this example.
Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
In Photo 2, two 7mm comparators have been installed on a dial caliper in an attempt to measure BSL. Using this approach, the BSLs differed sharply from the original [measurements]. The comparator-measured Bullet 1 BSL was 0.694” vs. 0.324” (original), Bullet 2 was 0.601” (comparator) vs. 0.430” (original), and Bullet 3 (shown in Photo 2) was 0.602” (comparator) vs. 0.463” (original). [Editor’s comment — Note the very large difference for Bullet 1, masking the fact that the true full diameter on this bullet starts very far back. You can use comparators on calipers, but be aware that this method may give you deceptive reading — we’ve seen variances just by reversing the comparators on the calipers, because the comparators, typically, are not perfectly round, nor are they machined to precision tolerances.]

Spring is just two days away (March 20, 2025). That means the shooting season in many areas will be starting soon. If you need ammo for your rifles and handguns it pays to comparison shop. Smart shooters can benefit by price-shopping to get the best deals on factory-loaded ammunition, particularly for popular cartridge types such as .22 LR, 9x19mm (9mm Luger), .357 Mag, .223 Rem (5.56×45), and 6.5 Creedmoor. It this article we list 15 reliable online sources for factory-loaded ammo. You may want to bookmark this page so you can quickly scan and price-check multiple vendors. In addition, you can use a service such as AmmoSeek.com.
Why Should You Shop for Ammo Online?
By shopping online for ammo, you can save money, get a wider selection, and get bulk discounts. GunDeals.com explains: “Online purchases [can] save you a lot of money [and can] also save your time… one of the most important advantages is definitively the huge selection.” With online retailers you can quickly compare prices, and you will often get a discount on a large order (300 rounds or more) that is not available in local stores. Note, with some large vendors such as Cabela’s and Sportsman’s Warehouse you can order online then pick up in a local store.
Are There Restrictions on Online Ammo Purchasing?
In most (but not all) U.S. states is it legal to order ammunition online to be shipped to your residence. However, you MUST check your State and local laws and regulations. In some states and/or cities, it is ILLEGAL to purchase ammunition online for shipment across state lines with direct delivery. For example, in California, all ammo must be purchased from a licensed ammo dealer/vendor with a state background check (so much for the Second Amendment)*. Likewise Washington DC, and Hawaii do not allow online ammunition purchases. And there are restrictions in New York City. In Alaska there are multiple shipping regulations that impact ammo deliveries from online sales so many vendors do not ship to Alaska.
*In some instances ammo can be purchased online from an out-of-state seller who will then ship to an authorized, in-state California vendor who may transfer the ammo for a fee with background checks as required by CA law.
Spring Groundhog Hunting — Fun and Challenging
Along with actual groundhog hunting, many shooters like to shoot paper and/or steel groundhogs in club groundhog competitions. These are fun matches that you can shoot with a variety of rifles. Our first choice would be a 22 BR for ranges out to 450 yards or a 6 BRA if targets are farther out. One popular match in the Northeast is the St. Thomas Ground hog shoot in Pennsylvania (see below).
