There is an excellent article about primers on the Shooting Times website. We strongly recommend you read Mysteries And Misconceptions Of The All-Important Primer, written by Allan Jones. Mr. Jones is a bona fide expert — he served as the manager of technical publications for CCI Ammunition and Speer Bullets and Jones authored three editions of the Speer Reloading Manual.
This authoritative Shooting Times article explains the fine points of primer design and construction. Jones also reveals some little-known facts about primers and he corrects common misconceptions. Here are some highlights from the article:
Size Matters
Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.
Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.
Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.
The Lee Hand Press Kit comes complete with: Breech Lock Hand Press, Ram Primer fittings, Powder Funnel, Case Lube, and one Breech Lock Quick Change Bushing.
The Lee Breech Lock Hand Press is a useful addition to any reloader’s tool collection. This Hand Press allows you to resize brass or seat bullets while at the range or away from your loading room. No it won’t replace your Co-Ax or Rockchucker, but this is a handy piece of gear. And it’s very affordable. Midsouth sells the Lee Breech Lock Hand Press Kit, with everything shown above, for $64.52. Or you can buy just the Hand Press by itself for $49.91 at Amazon. That’s a great deal.
Lee Hand Press Quick-Change Die Functionality
This Lee Press includes the Breech Lock Quick-Change Die Feature, so you can instantly change dies with just a twist of the wrist. One Breech Lock Quick Change Bushing is included. The Breech Lock Hand Press is light and compact. It tips the scale at a mere 1 3/4 pounds and overall product length is 11.5″. Note: the maximum overall length cartridge the Lee Hand Press can accept is 3.650 inches.
While we don’t recommend the Hand Press for major full-length sizing chores, it does a good job seating bullets. This makes it a handy “field expedient” tool when doing load development at the range. For example you can experiment with seating depth by loading a batch of cartridges at home with the bullets deliberately seated long. Then, at the range, you can re-seat the bullets progressively shorter (in a series of rounds), until you find the optimal Cartridge OAL.
Lee’s Hand Press is also great for decapping operations. One verified buyer reports: “I mostly use it for decapping while watching TV, with a universal decapper die. Of course it is also useful for other operations. I wouldn’t love sizing large rifle cases with it, but if you’ve prepped your cases on a bigger press you could comfortably take it to the range for load development, one round at a time, working right there at the line instead of making a bunch of loads at home that you’ll have to disassemble later. It’s smaller and more lightweight than it looks[.]”
Using Hand Press to Load at the Range
To learn more about using the Lee Hand Press in the field with a compact scale, read Reloading Without a Bench on GunsAmerica.com. Author Christopher Mace explains: “whether you want a better way to do load development, the capability to reload out of your ‘bugout bag’, or you’re short of space but wanting to get into reloading, the Lee Loaders and the Lee Hand Press offer you some options.”
He who dies with the most toys wins — right? Well Sinclair has another interesting gadget you can add to your reloading bench. The Sinclair Case Neck Sorting Tool lets you quickly sort brass by neck-wall thickness. For those who shoot “no-turn” brass, this can improve neck-tension consistency. Large variances in neck-wall thickness can cause inconsistent neck “grip” on the bullet. Generally, we’ve found that more consistent neck tension will lower ES and (usually) improve accuracy. We know some guys who shoot no-turn 6mmBR brass in competition with considerable success — but their secret is pre-sorting their brass by neck-wall thickness. Cases that are out-of-spec are set aside for sighters (or are later skim-turned).

How the Case Neck Sorting Tool Works
Here’s how the Sinclair tool works. Cases are rotated under an indicator tip while they are supported on a case-neck pilot and a support pin through the flash hole. The unit has a nice, wide base and low profile so it is stable in use. The tool works for .22 through .45 caliber cases and can be used on .17- and .20-caliber cases with the optional carbide alignment rod. The MIC-4 pin fits both .060 (PPC size) and .080 (standard size) flash holes. Sinclair’s Case Neck Sorting Tool can be ordered with or without a dial indicator. The basic unit without dial indicator (item 749-006-612WB) is priced at $59.99. You can also buy the tool complete with dial indicator (item 749-007-129WB) for $89.99. IMPORTANT: This sorting tool requires caliber-specific Case Neck Pilots which must be ordered separately.
Editor’s Comment: The purpose of this Sinclair tool is rapid, high-quantity sorting of cartridge brass to ascertain significant case-neck-wall thickness variations. Consider this a rapid culling/sorting tool. If you are turning your necks, you will still need a quality ball micrometer tool to measure neck-wall thickness (to .0005) before and after neck-turning operations.
Many years ago, when we decided to do a story about SAKO’s TRG series of rifles, we remembered our friend Terje Fjørtoft in Norway. Terje has owned, and hunted with, both the TRG-22 (in .308 Win), and its big brother, the TRG-42 (chambered in .338 Lapua Magnum). Unlike many TRG owners in the USA, Terje has carried his “tactical hunters” into the field, and tested their effectiveness on large game in both coastal and mountain environments, in warm weather and cold. Terje tells us the TRGs have proven to be rugged and reliable. And they are accurate. The .308 Win TRG-22 delivers about 0.45 MOA groups at 420 yards shot from bipod. The .338 LM TRG-42 shoots about 0.55 – 0.7 MOA at that distance.
A Tale of Two TRGsby Terje Fjørtoft
I live in Brattvåg, along the coast of Norway, but I hunt and shoot at the nearby island “Fjørtoft” (same as my last name) and a small island outside Fjørtoft. I grew up on Fjørtoft as a child, and we hunt seals there in the spring and fall. The large, top photo shows me with my black TRG-42 338 Lapua Mag (“LM”) during a seal hunt a couple years ago. Click on the thumbnail at right to watch a video that shows me shooting the .338 LM. Most of the photos in this story are from that hunt. Because the .338 LM was really “overkill” on the seals (and expensive to reload), I replaced that rifle with a TRG-22 in .308 Winchester.
We hunt seals primarily for wildlife control. This is because the seals carry an internal parasite, called “Kveis”, a small worm that breeds inside the seals (after eating contaminated fish). When the seals expel the Kveis into the water, the Kveis larvae are consumed by the fish and then the fish become unfit to eat. The parasite literally eats the fish from the inside out. It’s not very pretty and it has hurt our Norwegian fishing industry. So there is an important purpose for our seal hunting. We hunt mostly from islands, targeting the seals in the water, and retrieving them with a small boat.
Because the seals spend most of their time in the water, a seal-hunter needs a very accurate rifle [to take head shots at distance]. I like the TRG-22 because it is very accurate out of the box, with a very nice bipod that works well in the field. The stock is comfortable with good adjustment range. The TRG features a 10-rd magazine and the barrel is pre-threaded for a muzzle brake or suppressor.
I have also used my TRGs for hunting big game, deer and what Americans call “Elk”. You can see, further down on this page, a picture from a hunting stand taken late in the evening, in the fading light. Yes I successfully bagged a nice buck during that trip with my TRG-42. When hunting, I use a Leica 900 rangefinder, Swarovski 7×42 Habicht binoculars, and a Silva windwatch. For Optics on the TRG-22, I have a Zeiss 6-24×56 scope, in Tikka Optilock rings. To get more scope adjustment I milled 0.9 mm off the front scope base mount. The Zeiss is great for viewing small targets past 400 meters. It was very difficult to find a longer shooting place than 575 meters on this Island (Uksnøy) but I found a place where I can shoot out to 930 meters, and I’ve made an 80-cm steel gong for a target. At this range, the bullet must fly nearly all the distance over the water.
Terje Shooting the TRG-42 without suppressor. Big recoil, big flash.
Both the TRG-22 and TRG-42 are very accurate right out of the box. The only thing I did before I first shot the TRGs was to clean the barrels very thoroughly. This is because the SAKO factory test shoots the gun without cleaning the barrel. I also adjust the cheek piece upward when shooting the rifles with a big scope. However, if you raise the cheek piece too high you can’t get the bolt out without removing the whole cheek piece. The only real modification I’ve made to my TRGs was to put rubber foot pads on the feet of the SAKO factory bipod. This gives the bipod better grip on slick surfaces such as concrete, or the rocks on the offshore islands.
.338 LM vs. .308 Win — Smaller Can Be Better
A few years ago I had a black TRG-42 (338 LM), but after a year, I sold it, and ordered a TRG-22 from the SAKO factory. After a one-year wait, I got the new green TRG-22 in February this year. One main reason I changed to .308 Win was the cost of ammo. I can reload .308 Win ammo for about one-third the price that it costs to reload .338 LM. One other reason is that my usual shooting distance is about 390 meters–at that distance the .308 is more than effective enough. Also, with the .338 LM, the barrel and the suppressor heated up after only a few shots, but with my new .308, I can shoot at my own pace without this problem. After my most recent shooting trip I once again confirmed how accurate, and fun-to-shoot, the TRG-22 is. I think now the TRG-22 has become my favorite plinking gun.
Though it is fun to experience the big boom and flash of the .338 LM, I’ll admit that it is just too much rifle for most applications. The .338 LM is REAL overkill for seal hunting. Here in Norway we have a rule that the smallest caliber we can use is 6.5×55 with a 140gr (or heavier) bullet, but everyone who hunts seals knows that the seals stay mostly in the water, and therefore you must take a headshot at distance up to about 200 meters. Making the headshot with a smaller caliber is advised for two reasons. First, when a big .338 bullet hits the water, there is a danger it will skip and ricochet quite some distance. Second, if you use too powerful a load/gun/caliber and take a headshot on a swimming seal, the seal sinks like a rock.
Reloading for the TRG-22 (.308 Win) With the TRG-22, I found it was easy to get an accurate load. My groups with 155gr Scenars are consistently good with a variety of different powders. I’ve tried both light and heavy bullets, but I favor the 155gr Scenars over the 185gr Scenars because the 155s fly a lot faster and drop less.
Three loads (all with Fed 210m primers) that have worked well are: 155gr Scenar with VV N150, 885m/sec; 155gr Scenar with Norma N-11, 890m/sec, and 185gr Scenar, VV N150, 770m/sec. Norma N-11 is a low-cost powder for target shooting. N-11 is similar to Norma 203B or Norma 202 but it varies quite a bit from lot to lot.
I use a RCBS Rock Chucker press, and currently use a standard RCBS full-length die kit to reload my .308 rounds. However, I recently ordered a Redding Competition 3-die set with a .335 bushing. I look forward to trying the Reddings. I have just started to test different seating depths. The 155s just “kiss” the lands at 74.10 mm. I’ve tried 74.00 mm, 74.10 mm and 73.55 mm, but so far saw no significant differences.
Reloading for the TRG-42 (.338 LM)
For the .338 LM, I started with a 250gr Scenar and 95 grains of Vihtavuori N-170. That load was very accurate at about 850 m/sec, but it produced excessive muzzle flash. And, in the winter, the muzzle velocity was inconsistent, and there was too much unburned powder. Next I tried Norma N-15, which proved very accurate at about 880 m/sec. With that load I shot my best TRG-42 group at 380 meters. I set the 250gr Scenar to touch the rifling with 93.2 mm COAL, and I used Federal 215m primers in Lapua-brand brass. Norma MPR2 and VV N-560 (860 m/sec) also were very accurate with the 250 Scenar.
My seal hunting bullet was the 200gr Nosler BT. This bullet grouped very well with 90-94 grains Norma N-15. Velocity was about 970m/sec if I remember correctly. I also tried the 300gr Sierra MK, and got 1/2″ 3-shot groups at 100 meters with 93.5 grains of VV N-170, but this combination produced terrible groups at longer range.
Loading for the .338 LM was not difficult — about the same as loading for .308 Win, except that you use nearly twice the amount of powder. I didn’t crimp the bullets in the neck, didn’t use any special tricks or neck lube. I used RCBS .338 LM full-length die. That functioned, but it would not be my first choice today. Overall, my better loads in the .338 shot in the 0.5-0.7 MOA range. My best group was four shots in 25mm (1″) at 380 meters (416 yards).
Hunting in Norway
I’m not a competitive sport-shooter. Normally, the only time I go to a “commercial” rifle range is to take the test for my hunting license. Every year, I must re-qualify for a shooting license to hunt big game and seals.
Hunters Tested Annually
In Norway, you must pass an actual shooting test before you can hunt big game. This test requires five shots at a deer silhouette target at 100 meters. No rests are allowed–you must shoot off-hand or with a sling only. You have to place five shots inside a 30 cm circle over the front leg.
Every big game hunter that passes this test is authorized to hunt at “dusk and dawn” and in moonlight. So, we do a lot of our hunting in the twilight hours. However, no night-vision or artificial illumination (spotlights) are allowed. We usually hunt deer at dusk and dawn. In the evening, we go on post two to three hours before it is dark, and sit there waiting for the deer to show up–hopefully before it is too dark. In the morning we go to the post one hour before you see any light of the sun, and wait for the deer to show up until the daylight. But when it is full moon we sometime have enough light to hunt in the middle of the night. In the photo, you can see a deer through the scope of my TRG-42. This was very late in the evening. CLICK HERE for BIG Photo.
Sound Suppressors for Hunting Rifles
Suppressors are legal to use for hunting in Norway. I have suppressors on all my rifles, even my little CZ 452 in 17 HMR. To me, shooting a rifle without a suppressor is like driving a car without an exhaust system. The suppressor reduces both noise AND recoil significantly. With a good suppressor, there is no loss of accuracy. The only “negative” in using a suppressor is extra weight on the end of the barrel.
I crafted my own home-made suppressor. It’s similar to my commercially-made TRG-22 suppressor, but the core is made from titanium to be lighter in weight and more corrosion-resistant. I used a lathe at work to craft the inside of the new suppressor. The core of the unit is built from a 27.5 cm X 40mm round bar of titanium while the outer cylinder is made from a 42mm stainless steel tube. I wanted to use titanium for the exterior cylinder as well, but I couldn’t source the right size titanium tube.
Commercial Suppressor on TRG-42
Comparing .308 Win vs. 6mmBR I also have a 6BR hunting rifle (compensated of course). I have a lot of field time with the 6BR rifle, and feel very confident with that gun. When I got the Krieger 6mmBR barrel on the SAKO Varminter, I fell in love with that rifle from day one, and that rifle is my first choice for small game hunting.
I also like the TRG-22 gun very much and enjoy it more and more with each new field trip. That .308 is my big game rifle and my long-range target rifle.
I recently tested my TRG-22 rifle at 387 meters. This was just “fun shooting” at steel plates, and I didn’t measure groups. But I was happy with the results. Once I corrected for the 5 m/sec crosswind, I was able to put five successive shots on a 10 cm (4″) diameter steel target at 387 meters (423 yards).
My SAKO Varminter in 6mm BR and my TRG-22 are two very different rifles. The TRG-22 is much heavier. I guess the TRG-22 is about 6.5-7 kg while my SAKO 6BR is about 4.5-5 kg, both with suppressor, scope, and bipod. The 6BR with suppressor is much quieter than the TRG-22 with suppressor. The recoil of the 6BR is a lot softer than the TRG-22. So far my 6BR is more accurate. A typical three-shot group with the 6BR is 25-40 mm at 387 meter (423 yards), and that is with just 10X magnification from a Zeiss scope. With my TRG-22, my 3-shot groups run about 50-60 mm, shooting with bipod and beanbag. But I think with a better .308 Win reloading die and more practice, I can improve my groupings with the TRG-22.
SPEC SHEET
The SAKO TRG-22 and TRG-42 are built in Finland by SAKO, a subsidiary of Beretta. In America, the guns are distributed by Beretta USA. Both TRGs (22/42) are available in forest green or a matte black textured finish. A two-stage match trigger is standard.
The stock is somewhat unconventional. It is an external shell, bolted to an internal metal chassis. The action bolts directly to the chassis, without bedding. The injection-molded stock is adjustable for comb height, length of pull (with spacers), vertical butt-pad height and cast-off.
Weight TRG-22 4.7 kg (black) 4.9 kg (green)
Barrel TRG-22 660 mm (26″), hammer-forged, optional stainless or phosphate finish
In recent months, Forster Co-Ax® presses have been hard to find, as demand has out-stripped supply. But the folks at Forster Products are working hard to get these excellent presses out to vendors. Be patient, check with multiple sellers, and you should be able to find one.
If you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video embedded below. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market.
Video Shows Special Features of Forster Co-Ax Reloading Press
Forster Co-Ax Press Video Review
This is a very thorough review of the Forster Co-Ax done by Rex Roach. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.
The Co-Ax case-holder features spring-loaded, floating jaws. These jaws have two sets of openings, small and large. This allows the system to adapt to various rim diameters. The jaw plates can simply be reversed to switch from small jaw to large jaw. In the photo above, the Co-Ax is configured with the large jaw openings in the center.
What is the most-used piece of equipment on this Editor’s reloading bench? No it’s not my Rock-Chucker press, my priming tool, or even my calipers. The one item in near-constant use is a small, folding magnifying glass. Mine folds into a square case and offers 4X viewing with an 8X bifocal insert. With this handy tool I can inspect case mouths for burrs, check primer pockets, inspect meplats, and look for flaws on bullet jackets. I also use the magnifier to see rifling marks on bullets seated into the rifling, or check my bolt for galling. The number of uses is nearly endless. I keep one magnifier at my reloading bench and another in my range kit.
Folding magnifiers are so handy yet inexpensive that you should own a couple spares (including one in the range box). I bought my magnifier in a book-store, but you can also find them on Amazon.com and FoldingMagnifier.com starting at under $2.00. To see inside cases and dies and view fine details, consider the 5X Meromore Folding Magnifier with a built-in, battery-powered LED light, plus a 11X high-magnification insert.
With a decent small magnifier, you can easily see any minute flaws in your barrel crowns. That’s important because crown damage can cause hard-to-diagnose accuracy issues. We’ve known guys who spend weeks tinkering with loads, when the real problem was a worn-out or damaged crown.
The slide-out iLumen8, shown at left in top photo, offers 3X power with built-in illumination. An “Amazon’s Choice” item, this palm-sized magnifier is $18.95 on Amazon.
As a cartridge case is reloaded multiple times, burnt powder residue and carbon builds up on the inside of the case. Unless the case interior is cleaned in some fashion, eventually you’ll see a slight reduction in case capacity. One of our Forum members from Australia wonders about the effects of reduced case capacity: “If the capacity of the case decreases as the crud builds up, then it effectively reduces the size of the cartridge (inside). Wouldn’t that change the pressure produced from that of an equivalent clean case?”
Interesting Test of Case Capacity Changes
Forum member Fred Bohl has actual test results that can help answer the above question. Fred proved that, over a 20-reload cycle, the case capacity of uncleaned cases did decline a small amount. However, surprisingly, this did not seem to affect the actual chronographed velocity of the load. Extreme Spread (ES) did increase, but Fred believes the higher ES was due to changes in case-neck tension, rather than due to the slight reduction in case capacity. Fred reports:
“Back when beginning to use ultrasonic case cleaning, part of the motivation was to get the inside clean based on the assumption that allowing burnt residue to build up inside cases would affect capacity, and, ultimately, performance. An experiment was done to test this hypothesis. The load used, 30.5 grains of RL15 behind 107gr SMKs in a 6mmBR, was selected for best group and lowest ES in prior load development. It turned out to be 92% of initial case capacity and neither “full” or compressed. (I would suspect that different powders, load weight, and total case capacity might produce very different results.)
We took 30 cases of identical initial capacity and tracked three lots of 10 each:
LOT 1: No Internal cleaning LOT 2: Cleaned with media in tumbler LOT 3: Cleaned with Ultrasound machine
Each case (in each lot) was shot and reloaded 20 times. The simplified results after 20 reloads of each lot were as follows:
Lot 1 (not cleaned) – 0.3 to 0.4 gr. loss of capacity, 5 to 8 fps greater ES.
Lot 2 (tumble cleaned) – 0.1 to 0.3 gr. loss of capacity, 4 to 6 fps greater ES.
Lot 3 (ultrasonic cleaned) – no loss of capacity, no detectable change in ES.
FINDINGS There was no detectable correlation of velocity change to the lots. An oddity was that on very hot days Lot 1 velocities were, occasionally, slightly higher. From results of another ongoing test, I believe the above differences in ES are probably due more to variance in bullet grip tension than case capacity. The ultrasound cleaned cases (LOT 3) did maintain the lowest ES, but we are not 100% sure of the reasons why. More consistent bullet seating might be the reason.”
Editor’s NOTE: Fred’s results do suggest that carbon build-up inside the uncleaned cases might cause a slight increase in pressure that shows up on hot days. Fred has posted that: “A local shooter reported doing the 20 reload, no-clean test on a .308 that gave a loss of capacity of 2.0 grains, doubled ES and significant velocity changes. However, I don’t have any details on his load weight or powder.” Obviously a lot of carbon can build up with 20 reloads. Many shooters retire their brass before then.
Ultrasonic Cleaning and Neck Lube
Some time ago, Jason Baney did a lengthy test on ultrasonic cleaning. Jason found that with his ultrasonically-cleaned cases, the inside of the necks got so “squeaky clean” that he needed to use dry lube in the necks. Jason uses the $21.50 dry lube kit from Neconos.com. This applies ultra-fine Moly powder to the neck interior using small carbon steel balls.
Editor’s NOTE: We generally recommend full-length sizing your cases. But there may be some situations where you may want to body-size your brass in one operation, and then neck-size the case as a final operation for reduced run-out. Or, perhaps you have a non-bushing FL sizing die and you want to modify the neck sizing. This article explains how to use a Lee Collet Die to size case-necks.
For those who prefer to neck-size their brass (rather than full-length-size), the LEE Collet Die is a popular, inexpensive option. It works by having collet tangs or “fingers” press the neck against a central mandrel. A collet squeezes the case neck against a precision mandrel for a perfect fit with minimum run-out. The benefit is that you get a very straight neck, which is sized consistently from top to bottom. Canadian shooter Jerry Teo explains: “LEE Collet Dies produce sized cases with very low runout (measured runout is under .001″ using a Sinclair concentricity gauge). You also don’t get the build-up of brass at the base of the neck, as can happen with bushing neck dies. The neck-shoulder junction stays nice and crisp.”
Here’s a good video that explains how to use a Lee Collet Die to Neck-Size .243 Win brass:
UPDATE to LEE Collet Dies — Neck Protrusion Change
The Lee Precision website notes a small design change: “If you’re a long-time user of Lee Collet Neck Sizing Die you may notice we have modified the Collet so a small portion of the neck protrudes through the end of the Collet-sizing portion. This often-requested modification was implemented in 2019. This change allows the portion of the neck that protrudes above the Collet to remain in its fire-formed condition. This provides a natural flare to the case neck allowing easy and concentric seating of bullets. This is especially important when seating cast bullets or low-drag coated bullets.”
TIP ONE — Adjusting Tension
LEE Collet dies don’t have a specific mechanical adjustment for neck tension. But you CAN easily modify the die to provide more or less tension. If you want to adjust the neck tension using a Lee Collet die, you can simply chuck the mandrel in a drill and reduce the diameter with some sand-paper (to increase neck tension) or you can order a mandrel the next caliber larger and turn it to whatever diameter you want (the larger the mandrel diameter, the less the neck tension). You can also order custom mandrels from Lee sized to any diameter you want.
Regarding neck tension, Boyd Allen makes an important point: “The only way to properly get more neck tension with collet dies is to either reduce the diameter of the mandrel, or order a smaller-diameter mandrel from Lee. I remind folks that adjusting the die position to have more toggle at the top of the ram stroke (not the factory recommended method), or leaning on the press handle with more force than recommended will NOT increase neck tension.”
No Custom Lee Collet Dies For Now
In years past, Lee also offered Custom Collet Dies, made from two fired cases. Hopefully these will be available in the future. However, earlier this year, Lee announced it had suspended sale of most custom dies including Collet Dies: “March 17, 2021: Due to unprecedented order volume, we have suspended custom services for Collet Necksizing Dies, Full-Length Sizing Die Sets, Quick Trim Dies, Case Length Gauges, Factory Crimp Dies, and Bullet Molds until we are able to meet the required volume of our standard products.”
TIP TWO — Polish and Tune for Easy Case Removal
Some users have complained that their Collet Dies grab the case-neck too firmly, making the case hard to remove. There are solutions to this problem. First inspect the collet fingers and smooth the inner surface up a bit with polishing compound or an extra-fine sanding pad. Second, you can open up the fingers a little bit. LEE recommends that if your Collet Die is sticking, take a steel punch and tap the fingers apart a little bit so that the natural “unloaded” position is wider. Lastly, you should lightly lubricate the outside of the collet fingers (see arrows) before you re-assemble the die. This will ensure they slide smoothly. Also, to prevent the collet fingers from closing too tight, never load up the die with your press without putting a case in place first. Without a case neck between the collet fingers and the mandrel, the collet can clamp itself too tight as you raise the ram.
TIP THREE — Always Have a Case Inside When Operating Collet Die
Our friend Boyd Allen tells us that you need to follow directions and NEVER operate the die without a case inside. Boyd explains: “This is because doing so will spring the quadrents of the collet inward so that they interfere with the insertion of a case, and the user will have to figure out how to undo the damage if the die is to operate properly. This advice would not be needed if everyone read the instructions before using the die…. but many times, they don’t. Another thing that I tell new users is to take the die apart so that they will have a better chance of understanding how it works.”
TIP FOUR — Size Twice and Spin Your Case 1/8th Turn
After reaching fully “down” on your press handle, withdraw the case about an inch and manually rotate it about 1/8th (NOT 1/4 or 1/2) turn while still in the shell-holder, then size again. This will place the die’s collet petals on the four “high spots” of the case neck and will result in a rounder, more evenly-sized neck with slightly more bullet tension. This takes only about one second more per case and is well worth the slight extra effort. (We thank reader Stonecreek for this smart tip).
Shooting Prairie Dogs at extreme long range takes some highly specialized equipment. Forum Member VolDoc and his friends have taken long-range varminting to a whole new level. With his Savage-based, Hart-barreled 20 BR, VolDoc managed a verified 1,032-yard Prairie Dog kill, possibly the longest recorded with a .20-Caliber rifle. But that’s just part of VolDoc’s impressive precision varminting arsenal. Here we showcase three of VolDoc’s accurate rigs: his stunning English Walnut Diamondback 6BR/Dasher, his Nesika-actioned “Orange Crush” Dasher, and the 1K Prairie Dog-slaying 20 BR Savage.
Diamondback Switch-Barrel Rifle Specifications
The action is a Stiller Diamondback, drop-port. The custom stock is similar to a Shehane ST-1000, but crafted from 40-year-old English Walnut. [Editor’s note: the wood on this gun is gorgeous!] There are three barrels for the gun with three different chamberings: 6BR Brux 1:8″-twist HV; 6BRX Krieger 1:8″-twist HV, and 6mm Dasher Krieger 1:8.5″ twist fluted straight contour (no taper). The scope is a Nightforce 12-42x56mm, with 2DD reticle.
Comments: This rifle is a good study in comparison of the three different chamberings. On the same rifle platform (same stock and action), each of these barrels had killed prairie dogs over 1,000 yards. So if someone asks which is best, a 6BR, or 6BRX, or 6 Dasher, VolDoc says they are all effective. The improved cartridges will deliver higher velocities, which can be an advantage. On the other hand it is simpler to load 6mmBR brass right out of the box, and it’s easy to find an accurate load for the 6mmBR (see photo).
Nesika 6mmBR/Dasher Rifle Specifications
VolDoc’s “Big Orange Crush” rifle has a stainless Nesika ‘J’ action, with 2 oz. Jewell trigger, in a painted fiberglass Shehane ST-1000 stock. Originally a 6BR, the gun is now chambered as a 6mm Dasher with a .271 no-turn neck. The barrel is a 1:12″-twist Krieger fited with Vais muzzle brake. On top is a NightForce NXS 12-42x56mm scope with double-dot reticle. The double-dot gives precise aiming and lower dot can be used as an aming point, when you need a few more MOA of elevation in the field.
Comments: Big Orange Crush shoots 87gr V-Maxs into bugholes at 3,400 fps. VolDoc’s load with the 87s is very stout, more than 32 grains of Vihtavuori N-135 with Wolf SRM primers. Cases are full-length sized, with an 0.266″ bushing for the necks.
This 3400 fps load with the 87gr V-Maxs has accounted for hundreds of Prairie Dogs killed from 97 yards to 1,050 yards. The 87gr V-Max at this speed literally picks Prairie Dogs up and throws them 10 feet vertically and laterally. VolDoc reports: “The barrel now has more than 3,000 rounds down the tube and exhibits little throat fire-cracking and no loss of accuracy. I can’t explain why, it just hasn’t deteriorated yet. This rifle is my best-ever ‘go-to’ Prairie Dog rifle.”
Savage 20 BR Rifle Specifications
The action is a Savage Dual Port, with an aftermarket Sharp Shooter Supply (SSS) 4 oz. Evolution trigger. The stock is a modified Savage factory unit that has been pillar-bedded. The factory barrel was replaced with a 28″ Hart stainless, 1:9″ twist barrel fitted with a Rayhill muzzle brake. The gun is chambered in 20 BR with a 0.235″ no-turn neck. Kevin Rayhill did the smithing. To provide enough elevation to shoot at 1,000 yards plus, Ray fitted a +20 MOA Bench Source scope base. This +20 rail is very well-crafted, and made especially for the Savage Model 12.
Comments: VolDoc reports: “When I got the Savage back from Kevin Rayhill, it still had my 6 BR factory barrel on it, as I use it to compete in Factory-class regional matches. I put on the new 20 BR Hart barrel Kevin had chambered and quickly put in a full day of load development using the 55gr Bergers (0.381 G1 BC) and the 40gr V-Maxs. Both proved very easy to tune and I soon had my loads. My 55gr Berger load with runs about 3590 fps. Varget was very accurate with the 55s (see load dev. targets below).
The mild recoil of the 20 BR, along with a very good muzzle break (Rayhill’s design) enables me to spot every hit or miss myself. Kevin also re-contoured the underside of the Savage stock so it tracks straight back on recoil, also making seeing hits easier.”
The 20 Caliber 1000-Yard Prairie Dog Quest
Making the 1032-Yard Shot with a 20 BR by Dr. John S. (aka “VolDoc”)
This article covers my recent successful quest for a 20-caliber varmint kill past 1,000 yards. This may be a first — I couldn’t find anyone else with a confirmed 20-Cal Prairie Dog kill at 1000+. I started a thread on the Varmint section of the AccurateShooter.com Forum about building a 20 BR capable of 1,000-yard Minute of Prairie Dog accuracy and many said 20 Cal bullets just could not do it. Some came to my defense and said those that doubted had never studied the ballistics of the 20BR with the new Berger 55gr bullets now available. Well, folks, I can tell you, hitting a Prairie Dog at 1000 yards isn’t easy — but it IS possible. Here’s how it was done….
Gale-Force Winds and High Temps
After arriving at our Prairie Dog Ranch in Colorado, I soon realized my quest was going to be especially difficult because we had continual 40+ mph winds and 100° heat every day. We had a special place where Birdog and I had made many 1,000-yard+ kills in years past, so I knew the ideal location but needed a small window of opportunity either early morning or late afternoon. Based on past experience, I knew I needed about 21 MOA from my 100-yard zero to get to 1,000 yards. On the first day of the Safari, I shot the 20 BR in the 45 mph brutal winds and heat of 97°. But after about 20 shots, I connected on a dog and lifted him about three feet high. Well, that’s a start.
Winds Subside — Here’s Our Chance …
On the second day of our shoot, I had listened to the early weather forecast, so I knew that there was to be a brief period of light winds early in the morning. We were out on the Colorado prairie at daylight and the conditions were perfect. The sunrise was at my back and we had about a 10 mph tailwind. I looked through my Leica Geovid Rangefinder Binos and the Prairie Dogs were out for breakfast. I quickly ranged the targets and found a group at about 1,050 yards. The technique is to find the dogs, range them, click-up according to your ballistic chart and shoot.
My first shot was very, very close. I added about four clicks up and a couple of clicks left for windage and let another go. That shot threw dirt all over, but the dog didn’t even flinch. This is another good point to remember about long-range Prairie Dog hunting. To be successful, the dogs can’t be too skittish, because if they have been shot at even a few times, they will go down and stay down. So, you should have an agreement with those in your party as to where each member is going to be shooting and respect this boundary. Drive-by shooting style is OK if that’s your thing, it’s just not mine.
Hitting the Mark — Dead Dog at 1032 Yards
On the fourth shot, I saw the dog go belly up and kick its final throws. My quest for the 20-Caliber 1,000-yard Prairie Dog had become a reality. We confirmed the distance with our lasers at 1,032 yards. Our technique for retrieving a dead dog at that range is worth mentioning. When I killed that dog, I left it in the crosshairs of my Nightforce scope. My shooting buddy kept looking through the scope (of my gun) and guided me to the deceased dog using Motorola walkie-talkies. When I got to the dog I was jubilant. I marked it with my tripod and orange jacket, and we took some pictures. (See view through scope photo below). The 55gr Bergers require a center mass hit as they will not expand, especially at that range. I centered this dog in the head — his BAD LUCK, my GOOD.
After making the 1,032-yard kill, I shot many many other Prairie Dogs with the Savage 20 BR using the 40gr V-Maxs. The dog flights were spectacular — red mist and helicopters, counter-clockwise or clockwise on demand. I killed at least five at over 500 yards. I will not use the 55 Bergers on Prairie Dogs again since the quest is over. I will use the 40gr V-Maxs and 39gr Sierra BlitzKings for next trip’s 20 BR fodder.
