Bolt Action Reloading is a popular YouTube channel that has amassed 97,000 subscribers. For this Saturday Video Showcase we are featuring seven (7) interesting videos. If you’re getting started in reloading, definitely watch the video on Five Common Mistakes. And all handloaders can benefit from the videos which covers affordable tools, all under $50.00 (at time of filming).
Getting Started in Reloading — Lessons Learned
This is a very helpful video for anyone getting started in reloading. The host summarizes the important lessons he has learned over the years. Here he covers some of the common issues handloaders face and how to avoid problems as you get started. As he notes: “When you are getting started reloading, some things you learn the hard way. In this video I cover things that I wished I knew before I got started [reloading]. There were several things that held me back when I started and in this video we cover 10+ of them.”
Five Common Mistakes Made by Novice Handloaders
This video spotlights five (5) common mistakes made by people when they get started hand-loading ammunition. These are some of the most common errors and misconceptions that affect “newbie” reloaders. Here are the five common problems encountered by folks getting started in handloading:
1. Not Using LOAD DATA from a Reliable Source — Use verified, properly developed load data from a powder maker or bullet maker. Don’t trust private social media posts. And always start conservatively.
2. Inconsistent Case Sizing — this can be the result of sloppy die set-ups or not knowing how to measure cases correctly.
3. Cartridge Overall Length (COAL) Variances — Don’t assume that COAL book values apply to your ammo. You should measure your own cases based on your chamber, headspace, and bullet choice. AccurateShooter.com recommends you use QuickLoad or Gordon’s Reloading Tool software to help adjust loads for different COAL.
4. Hand-Loading Is Not Always a Money-Saver — For a cartridge you don’t shoot much (say a .30-06 for hunting only), hand-loading might not save you money once you count the cost of dies and tools.
5. Reloading Kits Are NOT Complete — Don’t assume that the $500 reloading kit you acquired (with press, powder measure, scale etc.) has all the components and tools you actually need. You will still need dies, comparators, and many other tools.
Primer Pocket Uniforming — Is It Worth the Time and Effort?
With Lapua and Peterson brass we have had very good results — great accuracy and with low ES and SD — using brass that has NOT had the primer pockets uniformed with some kind of cutter. We always do check to make sure there are no flakes or obstructions in the flash holes, but we generally do NOT need to cut into the pockets. But with lesser brands of brass you can benefit from uniforming your primer pockets. And yes there are some top shooters who DO uniform pockets even on premium-brand brass. That is up to you. This video explains the process for primer pocket uniforming and looks at some test results.
Developing a Load — OCW vs. 10-Round Ladder
This video talks about two methods of determining an accurate load. We include this video here because many people are curious about Optimal Charge Weight (OCW) load development. Frankly, however, we believe there are better, more reliable ways to find a good load — many people have wasted many hours and much barrel life on the OCW quest. NOTE: With a good cartridge of known accuracy, such as a 6mmBR or 6mm Creedmoor using top-quality brass, we really do NOT advocate either method described in this video. We suggest you do a search to find the best bullet choice and powder choices. Then, if you are shooting from the bench with a custom barrel, consider starting in the lands, about .003-.005 past first touch. NOT full jam!! If you are shooting in conditions where you may have to unload a round during a match, start .020″ back from first touch. Chronograph every round. Shoot three-shot groups at 100 yards, looking to keep all shots touching. Many people doing OCW waste a ton of time (and barrel life). And one bit of advice for people with average factory barrels — it may be pointless to expect anything much under 1 MOA from that barrel no matter what you do.
Handloading Cool Tools — All Under $50.00
Along with powder measure, dies, and reloading press, there are a wide variety of tools that can help achieve good results when handloading ammo. This Bolt Action Reloading video identifies ten (10) tools that can be acquired for $50.00 or less. Here is the list:
1. Check Weights (00:20) — These help ensure your scale is measuring properly.
2. Digital Calipers (00:57) — You can spend $200+ on calipers, but you can get good results from caliper that cost less than $50.00, and every reloader should have a back-up set of calipers.
3. Comparator Sets (01:26) — These are fittings that attach to calipers. Bullet Comparators are sized to fit a bullet diameter to get reliable base-to-ogive measurements. Case comparators fit the neck of the cartridge, allowing you to measure shoulder bump.
4. Stock Case Remover (02:48) — This allows you to remove a brass case that may be stuck in a die.
5. Imperial Sizing Die Wax (03:20) — There are many types of case lubricants, but Imperial Die Wax is still a popular choice and very affordable.
6. LEE Cutter and Lock Stud (03:44) — This is a cheap way to trim cases. We prefer a Forster trimmer or a deluxe power trimmer but LEE system is inexpensive.
7. Chamfering and Deburring Tools (04:38) — After brass is trimmed to length you need to chamfer and deburr the case necks. Good chamfering/deburring tools are “must have” items for hand-loaders.
8. Case Neck Brushes (05:50) — If you don’t tumble your brass it’s a good idea to brush the inside of your fired cases before seating bullets. A couple swipes is all it takes — and you may find you get more consistent seating if you leave a bit of carbon in the necks.
9. Primer Pocket Swage Gauge (Ballistic Tool) (06:24) — These little tools let you check the dimensions of your primer pockets.
10. Decapping Die (06:57) — The decapping die removes spent primers without sizing the case. This is very handy if you want to remove primers before tumbling brass. NOTE: If your cases have small-diameter flash-holes you need to check the diameter of the decapping rod.
11. Powder Trickler (07:40) — A good trickler is an absolute “must have” when manually weighing each charge. The trickler allows you to add a couple grains at a time.
12. Powder Funnel with Drop Tube (08:45) — While most folks have a basic funnel, a deluxe funnel with a drop tube helps to get a full charge and more consistent powder density.
13. Kinetic Bullet Puller (09:36) — This is like a hammer that holds a loaded round. Using kinetic energy this tool can unseat a bullet with a couple of whacks. However, if you must unload a large quantity of rounds you’ll want a cam-lock bullet puller (09:58) that works with your press.
14. Caliber Specific Reloading Trays (10:28) — These are handy if you are loading specific cartridges. There is less wobble for each round.
Setting Neck Tension with Expanders and/or Bushings
There are three main ways (in addition to collet dies), by which you can set the neck diameter on cartridge brass and thereby control neck tension or the “grip” on the seated bullet. First, the sizing die itself can reduce the neck diameter. This can be a fitted die with the neck honed to a precise diameter. Or, the die can take neck bushings, which allow a range of neck tensions via different bushing internal diameters. Because they allow a wide range of tension settings, bushing dies are popular and effective. You can also have a die that takes the neck dimension down a few thousandths, but then have an expander mandrel that brings the neck inside diameter to an exact dimension. This has the advantage of keeping the INSIDE of the neck perfectly round, with any variances in neck-wall thickness pushed to the outside. This Bolt Action Reloading video explains the use of neck bushings and expander mandrels.
Full-Length-Sizing vs. Neck-Sizing of Cases
NOTE: At AccurateShooter.com we recommend that handloaders always full-length size their brass for many important reasons. Virtually all champion shooters in multiple disciplines full-length size their brass. Full-length sizing can achieve record-setting accuracy, and, importantly, it offers consistent shoulder bump with each loading. But we know that people are curious about neck-sizing, so we are including this video.
This video compares identical charge-weight loads tested with full-length-sized 6.5 Creedmoor brass vs. neck-sized 6.5 Creedmoor brass. The tester states: “I use the 142gr Sierra Match King HPBT loaded with Alliant Reloder 16. There is velocity and group data at 150 yards. FYI, we recommend always full-length sizing most cartridge brass, bumping the shoulder about .003″ (or more if required in a semi-auto).”
Here are two different bullet types, seated to the same CBTO length, but different COAL. Note the shiny scratches on the bullets made by the comparator tool which indicates a point on the bullet ogive near where the ogive will engage the rifling.
Effects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 2 by Bryan Litz forBerger Bullets. Part One of this series focused on the importance of COAL in terms of SAAMI standards, magazine lengths, seating depths, and pressure levels. Another measure of length for loaded ammunition is highly important to precision, namely Cartridge Base to Bullet Ogive Length (CBTO).
Figure 2. Chamber throat geometry showing the bullet jump to the rifling or lands.
Look at Figure 2. Suppose the bullet was seated out of the case to the point where the base of the bullet’s nose (ogive) just contacted the beginning of the riflings (the lands) when the bolt was closed. This bullet seating configuration is referred to as touching the lands, or touching the riflings and is a very important measurement to understand for precision hand-loading. Due to the complex dynamics of internal ballistics which happen in the blink of an eye, the distance a bullet moves out of the case before it engages the riflings is highly critical to precision potential. Therefore, in order to systematically optimize the precision of his handloads, it’s critically important that the precision hand-loader understands how to alter bullet seating depth in relation to the barrel rifling. Part of the required knowledge is understanding how to accurately and repeatably measure the Cartridge Base To Ogive (CBTO) dimension. This is explained in the FULL ARTICLE.
Bryan Litz offers an extended discussion on how to measure CBTO using different tools and methods, including the Hornady OAL gauge. You can read this discussion in the full article found on the Berger Bullets website. CLICK HERE to Read Full Article.
Why Not Use CBTO as a SAAMI Standard?
If CBTO is so important to rifle accuracy, you might ask, “Why is it not listed as the SAAMI spec standard in addition to COAL?” There is one primary reason why it is not listed in the standard. This is the lack of uniformity in bullet nose shapes and measuring devices used to determine CBTO.
Benefits of Having a Uniform CBTO
There is another aspect to knowing your CBTO when checking your COAL as it pertains to performance. With good bullets, tooling, and carefully-prepared cases you can easily achieve a CBTO that varies less than +/- .001″ but your COAL can vary as much as .025″ extreme spread (or more with other brands). This is not necessarily bad and it is much better than the other way around. If you have a CBTO dimension that varies but your COAL dimension is tight (within +/- .002″) then it is most likely that your bullet is bottoming out inside the seater cone on the bullet tip. This is very bad and is to be avoided. It is normal for bullets to have precisely the same nose shape and it is also normal for these same bullets to have nose lengths that can vary as much as .025″.
Summary of Cartridge Base To Ogive (CBTO) Discussion
Here are four important considerations regarding bullet seating depth as it relates to CBTO:
1. CBTO is a critical measurement to understand for handloaders because it’s directly related to precision potential, and you control it by simply setting bullet seating depth.
2. Tools and methods for measuring CBTO vary. Most of the measurement techniques have pitfalls (which may give rise to inconsistent results) that you should understand before starting out.
3. A CBTO that produces the best precision in your rifle may not produce the best precision in someone else’s rifle. Even if you have the same rifle, same bullets, same model of comparator gauges, etc. It’s possible that the gauges are not actually the same, and measurements from one don’t translate to the same dimension for another.
4. Once you find the CBTO that produces the best precision in your rifle, it’s important to allow minimal variation in that dimension when producing quality handloads. This is achieved by using quality bullets, tooling, and properly preparing case mouths and necks for consistent seating.
A while back, our friend Bill Marr of Rifleshooter.com conducted a fascinating 6mm Creedmoor barrel cut-down test that reveals how velocity changes with barrel length. This time Bill started with a 24″ Proof Research stainless steel barrel on a Howa action. Bill says this was a well-used barrel, with over 1800 rounds through it. So, the velocities might be a bit different than a new barrel of similar length. Bill cut the barrel down in one-inch increments. Here are some results from the test:
For this latest test, Rifleshooter cut the barrel in one-inch increments from 24″ to 16.1″ (just over legal minimum). Velocities were measured with a MagnetoSpeed V3 chronograph mounted on arm attached to the stock. This allowed the chrono to be adjusted inwards as the barrel was cut shorter, inch by inch.
For the 6mm Creedmoor cartridge, Bill loaded Hornady 108gr ELD Match bullets over 41.5 grains of Hodgdon H4350 with CCI 200 primers in new Starline brass.
The results were interesting to say the least. Bill reports: “Muzzle velocities ranged from 2,893 ft/sec at 24″ to 2,598 ft/sec at 16″ for a decrease in muzzle velocity of 295 ft/sec. Muzzle velocity changes per inch of barrel length ranged from 6 ft/sec per inch between 20 and 19 inches to 63 ft/sec per inch between 19 and 18 inches. Average velocity change per inch of barrel length was 37.9 ft/sec.”
Bill concludes: “An average drop of 37.9 ft/sec/inch of barrel is fairly significant and is what would be expected with a fast moving 6mm cartridge like the 6mm Creedmoor. While I’m used to seeing 6mm Creedmoors with slightly longer barrel lengths than 24″, when coupled with a sound suppressor the additional length can make moving the rifle quickly more difficult.
I’d suggest staying with longer barrel lengths wherever possible with this cartridge. At shorter lengths, it does give up more performance than its big brother the 6.5 Creedmoor.”
More 6mm Creedmoor Velocity Data from 2017 Cut-Down Test
If you’re curious about 6mm Creedmoor velocities at longer barrel lengths, back in 2017 Rifleshooter completed a 6mm Creedmoor barrel cut-down test from 31 inches all the way down to 17 inches. The test included four bullet types from 95 grains to 110 grains. With the 110gr Sierra MK, velocity at 31″ was an impressive 3110 fps. Surprisingly the velocity didn’t decrease that much for the first few inches. Even at 26″ (a five-inch reduction), measured velocity with the 110s was 3073 fps, a loss of 7.4 fps per inch on average. With a barrel shortened all the way to 20″ however, velocity had dropped down to 2949 fps, a significant (161 fps) loss. CLICK HERE for complete results from that 31″-17″ Barrel Cut-Down Test.
Put the same load in a variety of barrels (with the same length and chamberings) and you’ll see a wide variance in muzzle velocity. In fact, it’s not unusual to see up to 100 fps difference from one barrel to the next. We demonstrated this with a comparison test of Lapua factory ammo.
Chron Testing Lapua Factory Ammo
At our Southern California test range some years ago, we chronographed Lapua 105gr 6mmBR factory ammo in three different 8-twist barrels of similar length. The results were fascinating. Lapua specs this ammo at 2790 fps, based on Lapua’s testing with its own 26″ test barrel. We observed a speed variance of 67 fps based on tests with three aftermarket barrels.
Barrel Velocity Variance
Brand ‘S’ and Brand ‘PN’ were pre-fit barrels shot on Savage actions. Brand ‘K’ was fitted to a custom action. All test barrels were throated for the 100-108 grain bullets, though there may have been some slight variances in barrel freebore. With a COAL of 2.330″, the rounds were “jumping” to the rifling in all barrels.
Among the four barrels, Brand ‘PN’ was the fastest at 2824 fps average — 67 fps faster than the slowest barrel. Roughly 10 fps can be attributed to the slightly longer length (27″ vs. 26″), but otherwise this particular barrel was simply faster than the rest. (Click Here for results of 6mmBR Barrel Length Velocity Test).
IMPORTANT: Results Are Barrel-Specific, Not Brand-Specific
These tests demonstrate that the exact same load can perform very differently in different barrels. We aren’t publishing the barrel-makers’ names, because it would be wrong to assume that ‘Brand X’ is always going to be faster than ‘Brand Y’ based on test results from a single barrel. In fact, velocities can vary up to 100 fps with two identical-spec barrels from the SAME manufacturer. That’s right, you can have two 8-twist, 26″ barrels, with the same land-groove configuration and contour, from the same manufacturer, and one can be much faster than another.
Don’t Demand More Than Your Barrel Can Deliver
We often hear guys lament, “I don’t get it… how can you guys get 2900 fps with your 6BRs and I can only get 2840?” The answer may simply be that the barrel is slower than average. If you have a slow barrel, you can try using more powder, but there is a good chance it may never run as fast as an inherently fast barrel. You shouldn’t knock yourself out (and over-stress your brass) trying to duplicate the velocities someone else may be getting. You need to work within the limits of your barrel.
Factory Ammo Provides a Benchmark
If you have a .223 Rem, 6mmBR, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, 6.5×55, .308 Win, .30-06 Springfield, or .338 LM Rifle, we recommend you buy a box of Lapua factory-loaded ammo. This stuff will shoot great (typically around half-MOA), and it can give you a baseline to determine how your barrel stacks up speedwise. [Editor’s NOTE: The original test was conducted in 2008. The velocity of current-production Lapua factory ammo might be higher or lower, so your results may vary.]
When you complete a new 6mmBR rifle, it’s definitely smart to get a box of Lapua factory ammo and chronograph it. That will immediately give you a good idea whether you have a slow, average, or fast barrel. Then you can set your velocity goals accordingly. For example, if the factory 105gr 6BR ammo runs about 2780-2790 fps in your gun, it has an average barrel. If it runs 2820+ in a 26″ barrel (or 2835 fps in a 28″), you’ve got a fast tube.
Have inflation (and supply chain shortages) affected the price of powder? You bet. Probably WAY more than you could imagine. Forum member “Two Time HM LR” posted this interesting photo (above) showing Hodgdon powder prices from 1978, as sold by O.K. Weber in Oregon.
Now the prices — $20 to $44 — may not get your attention at first. But take note that these numbers are for EIGHT pound jugs. Yep eight-pounders were all under $45! For example, H4895 was $44 for 8 pounds back in 1978, 45 years ago. And H335 was $20 for eight pounds — that’s just $2.50 per pound!
These days a single pound of a desirable powder such as H4831 might cost $65 at some stores IF you can find it at all. On Hodgdon’s web site, H4831 powder is priced at $62.99 per pound in May 2025. Using that current $62.99/lb figure, H4831 is now over ELEVEN times higher than it was in 1978, when H4831 cost $44 for 8 pounds, i.e. $5.50 per pound.
Here are some comments from our Forum Members:
“Heck those prices are just about the same as current ones, just a little smaller container now.” — Joe
“I’ve got some H4831 in a can marked ‘WWII Surplus Powder’ with a price tag of $2.75. We’ll never see that again either.” Rick in Oregon
“1978 prices and [2025] income would be nice. Unfortunately that doesn’t work. If you compare prices and income, powder cost about the same. You also have to discount the temporary gouging that we are seeing.” — Tmwinds
“So I used to buy gas for 10 cents per gallon and they’d pump it, check the oil, and clean the windshield.” — Pirate Ammo
One comment suggests that the powder price hike actually tracks general U.S. currency inflation over the last four decades. So perhaps powder price increases are not as bad as they seem, when compared to how all prices have risen since 1978:
“Using H4895 [8 lbs.] as a comparison basis at $58.50 (list price) in 1978 calculates it to $287 in today’s money. Looking at … prices it looks like [8 lbs. of H4895 would cost $430] for the same item in today’s money [at Powder Valley], so it really hasn’t gone up [that much as corrected for inflation]. Availability is another issue though[.]” — Drover
Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion.
Cartridge Efficiency: A Primer (pun intended!)by USAMU Staff
The U.S. Army Marksmanship Unit (USAMU) published a series of reloading articles on its Facebook Page. In this article, the USAMU discusses cartridge case efficiency and its benefits. While this is oriented primarily toward NRA High Power Rifle and Long Range (1000-yard) competition, these factors also apply to medium/big game hunters. Assuming one’s rifle and ammunition are accurate, key considerations include ballistic performance (i.e., resistance to wind effects, plus trajectory), recoil, and throat erosion/barrel life.
Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion. A classic example in the author’s experience involved a featherweight 7x57mm hunting/silhouette rifle. When loaded to modern-rifle pressures, just 43-44 grains of powder pushed a 139gr bullet at 2900 fps from its 22″ barrel. Recoil in this light rifle was mild; it was very easy to shoot well, and its performance was superb.
An acquaintance chose a “do everything” 7mm Remington Magnum for use on medium game at short ranges. A larger, heavier rifle, it used ~65 grains of powder to achieve ~3200 fps with similar bullets — from its 26″ barrel. Recoil was higher, and he was sensitive to it, which hampered his shooting ability.
Similarly efficient calibers include the 6mm BR [Norma], and others. Today’s highly-efficient calibers, such as 6mm BR and a host of newer developments might use 28-30 grains of powder to launch a 105-107gr match bullet at speeds approaching the .243 Winchester. The .243 Win needs 40-45 grain charges at the same velocity.
Champion-level Long Range shooters need every ballistic edge feasible. They compete at a level where 1″ more or less drift in a wind change could make the difference between winning and losing. Shooters recognized this early on — the then-new .300 H&H Magnum quickly supplanted the .30-06 at the Wimbledon winner’s circle in the early days.
The .300 Winchester Magnum became popular, but its 190-220gr bullets had their work cut out for them once the 6.5-284 and its streamlined 140-142gr bullets arrived on the scene. The 6.5-284 gives superb accuracy and wind performance with about half the recoil of the big .30 magnums – albeit it is a known barrel-burner.
Currently, the 7mm Remington Short Action Ultra-Magnum (aka 7mm RSAUM), is giving stellar accuracy with cutting-edge, ~180 grain bullets, powder charges in the mid-50 grain range and velocities about 2800+ fps in long barrels. Beyond pure efficiency, the RSAUM’s modern, “short and fat” design helps ensure fine accuracy relative to older, longer cartridge designs of similar performance.
Recent design advances are yielding bullets with here-to-fore unheard-of ballistic efficiency; depending on the cartridge, they can make or break ones decision. Ballistic coefficients (“BC” — a numerical expression of a bullet’s ballistic efficiency) are soaring to new heights, and there are many exciting new avenues to explore.
The ideal choice [involves a] balancing act between bullet BCs, case capacity, velocity, barrel life, and recoil. But, as with new-car decisions, choosing can be half the fun!
Factors to Consider When Evaluating Cartridges
For competitive shooters… pristine accuracy and ballistic performance in the wind are critical. Flat trajectory benefits the hunter who may shoot at long, unknown distances (nowadays, range-finders help). However, this is of much less importance to competitors firing at known distances.
Recoil is an issue, particularly when one fires long strings during competition, and/or multiple strings in a day. Its effects are cumulative; cartridges with medium/heavy recoil can lead to shooter fatigue, disturbance of the shooting position and lower scores.
For hunters, who may only fire a few shots a year, recoil that does not induce flinching during sight-in, practice and hunting is a deciding factor. Depending on their game and ranges, etc., they may accept more recoil than the high-volume High Power or Long Range competitor.
Likewise, throat erosion/barrel life is important to competitive shooters, who fire thousands of rounds in practice and matches, vs. the medium/big game hunter. A cartridge that performs well ballistically with great accuracy, has long barrel life and low recoil is the competitive shooter’s ideal. For the hunter, other factors may weigh more heavily.
Cartridge Efficiency and Energy — Another Perspective
Former Lapua staffer Kevin Thomas explains that efficiency can be evaluated in terms of energy:
“Cartridge efficiency is pretty straight forward — energy in vs. energy out. Most modern single-based propellants run around 178-215 ft/lbs of energy per grain. These figures give the energy potential that you’re loading into the rifle. The resulting kinetic energy transferred to the bullet will give you the efficiency of the round. Most cases operate at around 20-25% efficiency. This is just another way to evaluate the potential of a given cartridge. There’s a big difference between this and simply looking at max velocities produced by various cartridges.”
This story is about a great shooter, Joe Hendricks Jr., and his Eliseo RTS Tubegun, chambered in 6mm Competition Match. With this versatile rifle, Joe Hendricks Jr. won the 2019 CMP Cup Aggregate Title for Match Rifles. Joe comes from a long line of talented marksmen. His father AND his grandfather are elite competitive shooters. His dad has been a National Champion, and all three generations have shot together, shoulder to shoulder, on the Remington Rifle Team. Like grandfather, like father, like son.
Joe says: “I think it’s pretty cool that there have now been two major Across the Course Championships won by a Hendricks using a Gary Eliseo chassis, one by me this year, and one in 2014 when my father (Joe Hendricks Sr.) won the NRA National Championship.”

Joe Hendricks Jr.’s Rifle — Eliseo RTS Chassis, Rem 40X Action, Krieger Barrel
Joe’s rifle is built on a Competition Machine RTS Target Model chassis. This Tubegun features a Remington 40X action with Pacific Tool & Gauge Bolt and Jewell trigger. The scope is a Leupold 6-18x40mm. The barrel is a Krieger chambered in 6mm Competition Match. Joe explains: “The 6mm Competition Match is a cartridge that my dad came up with. It is basically a .243 Winchester with a 31° shoulder.”
If you look carefully in the photo below, you’ll note the silver-toned, adjustable butt-plate. That’s an upgrade Joe added: “I did a small modification to the stock, where I put on an Anschutz buttplate instead of the standard one Gary Eliseo uses. This Anschutz hardware provides a little bit more adjustability.”
Here Joe Hendricks Jr. fires at 200 yards from the standing position.
The Standing Position — Why It’s Critical to Match Success
Joe told us: “As far as shooting strategies and training methods go, I shoot a lot of standing practice — at least 50 shots per session. I still train the other positions of course, but I believe if you start your day off with a great standing score, it really makes the rest of the day easy because then you don’t feel like you’re playing catch-up the whole time.”
Joe explains: “When I’m shooting standing, I shoot in a manner very similar to the way that Carl Bernosky does. He’s written a few articles about the standing position. He always talks about making sure the shot goes off inside his hold, and I’m the same way. I don’t try to do too much. I just let the gun do its thing and when/if it stops in the Ten Ring, I shoot the shot. If it doesn’t, I don’t.”
About the CMP Cup Two-Day Course of Fire
The CMP Cup is a two-day match comprised of two, 1000-point Aggregates, for a 2000-point Grand Agg. Each day, the competitors fire 100 shots total from the 200, 300, and 600 yard lines. The match starts with 20 shots slow fire standing at 200 yards. Next are two, 10-shot, rapid fire strings in 60 seconds from the sitting position. Next are two, 10-shot strings in 70 seconds prone at 300 yards (rapid fire prone). Each day’s course of fire concludes with two, 20-shot sequences of slow-fire prone at 600 yards.
6mm Competition Match Cartridge — Slower Powder Yields Better Barrel Life
My dad was shooting a 6XC for a while and was getting tired of going through almost two barrels a year. So, he came up with the 6mm Competition Match. Like I said, it is a .243 Winchester with a 31-degree shoulder. This delivers the same (if not better) velocity as the other popular 6mm cartridges, but we get almost double the barrel life because we increased the case capacity, so we can shoot a slower burning powder. The barrel I took to Camp Perry that won the CMP Cup had over 3700 rounds on it when I was finished. [EDITOR: Take note readers! Most 6mm barrels are toast after 2500 rounds.] Granted it definitely needed to come off at that point, but it obviously was still shooting well enough to win!
Accurate Load with Peterson Brass, Berger Bullets, and Vihtavuori N165
The two loads I shot all week were Berger 108gr BT behind Vihtavuori N165 in Peterson Cartridge Company brass for 200 and 300 yards, and then Berger 115 VLD behind N165 in Peterson brass for 600 yards. Both loads are easily going over 3000 FPS. I try to only use the best components for reloading, so that’s why I go with Berger, Vihtavuori, and Peterson. Obviously Berger and Vihtavuori quality are pretty known, but I believe Peterson is right up there with Lapua[.] I’ve visited the Petersen factory many times. I’m always blown away by the time and effort Peterson puts into everything.
Winning Marksmanship — the Mental Game
The other big thing I’ve been focusing on lately is my mental game. In order to be at the top of a sport, regardless of the sport, the athlete has to have a solid mental approach. For me, I’ve learned that my key is confidence. A good shooting buddy, who was with me the first day of the CMP Cup, suggested I was arrogant because I kept telling him I was going to win. Then I told him it was confidence not arrogance. If I was confident in my ability, I did not think there was any way I could lose. [Editor: To help build confidence and visualize success, we recommend With Winning in Mind, by Lanny Bassham, an Olympic gold-medal winning marksman.]
All in the Family — Three Generations of Hendricks Marksmen
Joe’s father, Joseph Hendricks Sr., has been a National Champion rifle shooter. Joe’s grandfather, Gary Hendricks, is also a talented marksman. In fact, all three men — grandfather, father, and son — shot together on the Remington Rifle Team. Joe says that the shooting sports have helped build strong family bonds. He and his father enjoy shooting together, and competing against one another: “I learn so much just by watching my dad… shoot. Even though I have been competing for 10 years now, I’m still incredibly new to the shooting sports compared to my dad. My father is always there to help.”
“I feel very privileged to have grown up in the family that I did, with not only my father as a competitive shooter, but my grandfather as well. I definitely would not be the person I am today, let alone the shooter, without either of them. At one point, all three of us were on the Remington Rifle Team. I’ve had the opportunity to shoot team matches with all three of us on one team, as recently as this past summer.”
“Initially when I began shooting competitively, I was putting a lot of pressure on myself. I wanted to be as good a shooter as my dad and grandfather. I was trying so hard that it was really affecting my scores negatively. Then one year, I told myself I was just going to have fun, and not worry about match scores. That year was the year I really started to win things, and shoot some good scores.”
“When my father won the NRA National Championship in 2014, I was so proud, but along with being proud, all it did was make me more motivated. Ever since I started shooting, I wanted to win a National Championship, but after he won, it just fueled my fire more. There is a bit of father/son rivalry. It’s a lot of fun if we are shooting right next to each other at the same time. We just give each other crap about shooting a bad a shot, or shooting a lower score by a point or an X.”
“My dad started shooting when he was around 10, so he has a vast amount of knowledge compared to most people, especially me. He is always there to help whenever I have a question on anything firearm or shooting related. To this day, whenever I’m done with a match, I always talk to my dad. He always has time to listen to what I have to say.”

Today is May Day, May 1st, so we are well into springtime. The woes of winter are behind us. 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. BarrelCool In-Action Fan
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 ingenious BarrelCool device. This little yellow gadget fits in your action with a blower tube that goes into the chamber. A small electric fan blows cooling air through the barrel. It really works — folks who’ve purchased the $44.95 Barrel Cool and run temp strips on their barrel say the BarrelCool can significantly reduce the time it takes to cool down a hot barrel.
In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. BarrelCool is a simpler, less costly, and much handier solution. Priced at $44.95, this small device can potentially can save you money by extending barrel life. To see how Barrelcool works, watch the video below:
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 V model for $1183.99 on Amazon (#ad — you must add to cart to see this price). Or you can get the 4-16x50mm Burris Eliminator III model for $1167.40 on Amazon (#ad). Note: the Eliminator V has been replaced by the compact Eliminator 6, but that newer model costs $2499.99. The Eliminator III and V both offer better value for the price.
4. Hornady 17 HMR V-Max Loaded Ammo
For those distant prairie dog shots, you’ll want a centerfire round with some reach, 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 AmmoASAP.com for $12.05 ($0.24 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. 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 $12.66 — so figure it’ll cost you about $1.27 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.
