With the huge popularity of NRL22 and PRS rimfire matches, along with the growth of rimfire benchrest events, and local rimfire fun matches, we’ve seen heightened demand for all types of .22 LR ammunition. Plus the high cost of centerfire bullets and limited availability of powders and primers has pushed many centerfire shooters into the rimfire fold. Accordingly, quality .22 LR ammunition has been harder to find this year, and prices have been escalating. Thankfully, if you use Ammoseek.com, you can still find most types of .22 LR ammunition, from bulk-pack plinking fodder to high-end Lapua, ELEY, RWS, SK, and Norma.

As the PRS and other tactical/practical competitions continue to grow, a guy tends to wonder, just how good are the top competitors? And what are they actually doing (and viewing) as they complete a stage? Well, a great video from the Long Range Precision Shooters YouTube Channel let us see what the best in the sport see through their scopes when they shoot.
This video features Dave Preston, 2015 National Champion and consistent top performer, shooting the PRS Skills barricade. Dave Preston has been considered among the very best in the nation running this PRS stage. Dave nearly always shoots 100% with the fastest recorded time. In this video you’ll see him successfully engage all eight shots in under 43 seconds — that’s crazy fast. This includes a POV sequence (4:35 time-mark) showing the actual view through Dave’s scope as he completes the stage.
Watch this video! Dave offers excellent advice on gun-handling and body positioning for barricades. Listen to what he says and you WILL shoot better.
This video features the PRS Skills Barricade, an 8-round, 4-position stage featured at the majority of PRS matches throughout country. It’s called a “Skills Stage” as it is run the same way at every national match and gives shooters the ability to compare skill levels based on hit percentage and speed.
The target is a 10″ plate at 400 yards. There are four different positions, with two shots each. Most people run this stage in about 70 seconds, some in the mid-60s, the greats in the high 50s, and Dave does it in the low 40s… mighty impressive!
The Right Gear Aids Stability and Lets You Shoot Faster
Let’s also take a look at two pieces of gear that really helped Dave Preston get stable and shoot fast.
1. BARRICADE BAG — To Get Stable, Really Stable
In the video Dave is using a Solo Sac from Short Action Precision This bag was designed by USMC Solomon Mansalala. It’s a very soft/dense bag and is popular at matches.
The other bag that sees a LOT of use, and is far and away the most used, is the patented Gamechanger Bag from Reasor Precision Solutions and Armageddon Gear.
2. MUZZLE BRAKE — To Make Your Follow-Up Faster
You’ll notice that in the video the rifle is very steady through firing, even though he is not applying a lot of pressure to the rifle. Dave is using a Hellfire Muzzle Brake from Area 419. Combined with the soft-recoiling 6mmBR cartridge he is able to spot his impacts and make adjustments, and can also make very fast follow-up shots as his rifle hasn’t bounced way off target.

What can happen when the bottom-most primer in a primer feed tube goes off? A big bang, that’s what. Some or all of the primers in the vertical feeding tube can go off in a chain detonation. That’s exactly what happened to Dustin Ellermann, Top Shot Season 3 Champion. Scary experience, but thankfully Dustin was not injured. He writes: “Super thankful that I was wearing my Wiley X eye protection this weekend when I was reloading some .223 rounds. My press detonated nearly 100 small rifle primers. Shown here is the magazine feed tube. Not fun but it could have been much worse. Stay safe!”
When working with progressive reloading presses, you should definitely wear eye protection. Dustin’s chain detonation experience proves that — without a doubt. Remember you only have one set of eyes!
RCBS APS Strips — Alternative to Primer Tubes When you stack a column of primers in a single metal tube, you’re asking for trouble. As Dustin Ellermann learned, when one primer fires, the entire column can follow suit in a chain detonation. Thankfully, you do have options when it comes to primer feeding on a progressive press. RCBS developed an innovative, smart system with primers in horizontal plastic strips. Instead of being stored in a vertical tube, primers are placed in flat, plastic “APS” strips, with a ring of plastic separating each primer. Moving horizontally, primers are never stacked, so the chance of a chain detonation is reduced dramatically. The re-usable APS strips are color-coded for different primer types. You can buy CCI “pre-loaded” primer strips, or you can insert any brand of primers into strips using an RCBS strip-loader tool.
RCBS APS Strip Priming System This video shows how to use APS primer strips wiht a bench-mounted priming system.
AccurateShooter.com Editor Uses Strip Primers
This Editor owns an RCBS Pro-2000 progressive press. The RCBS strip-priming system was one key reason I selected the RCBS Pro-2000 over similar-priced progressives from Dillon and Hornady. I believe the strip primer system is safer, more positive, and easier to use. Before I purchased my RCBS progressive, I “road-tested” the competition. I loaded hundreds of rounds on each of four different progressives: Dillon 550B, Dillon 650, Hornady Lock-N-Load, and RCBS 2000. I was concerned about the primer feed tubes on the Dillons, and I found the RCBS rotary powder measure was much more precise (and easier to adjust) than the sliding bar system on the Dillon machines. The RCBS priming system was definitely more fool-proof than the system on the Hornady press (a first-generation L-N-L that had issues with primer feeding). After “test-driving” blue, red, and green brand progressives extensively, I settled on the RCBS Pro-2000. A decade later, I still think I made the right choice. I like the APS strips for big jobs, and I can also use them in the RCBS hand-priming tool (shown below). With the strips, it’s easy to prime 20 or 40 cases at a time, and then switch to another type of primer for comparison testing.
NOTE: Unfortunately, most of the RCBS APS system tools are no longer in production. But the tools and strips are still available on eBay and many reloading Forums, in some cases “new in box”. This Editor’s APS hand priming tool is still working great after 15 years.
The APS priming system also works with press-mounted priming tool, bench-mounted tool, and APS hand-tool. EdLongRange uses the press-mounted tool: “I also like the APS approach but use the press-mounted unit (saves your hands/wrists — and I haven’t had a need for a progressive press in over 20 years). Loading the primers in the strips is a bit of a PITA but very manageable. As with all tools there is a learning curve.” CLICK HERE for video showing strip-loading tool and press-mounted APS tool. The RCBS press-mounted tool is no longer in production by RCBS, but you can still find it in some stores or on eBay.

Jewell triggers are still the most-used triggers on competition benchrest and F-Class rifles and they are also popular for hunting, varmint, and tactical rifles (with or without safeties). While a Jewell trigger can work for years with minimal maintenance, if the trigger becomes gunked up, it may be necessary to disassemble the trigger for a thorough cleaning. Our friends Ed and Steve, aka the 6.5 Guys, have produced a helpful video that shows how to disassemble and then reassemble a Jewell trigger.
Why You May Need to Disassemble Your Jewell Trigger — the 6.5 Guys
Jewell triggers are a popular choice in the sport of long range precision shooting, and like everything else require regular cleaning and maintenance. In most cases they can be cleaned with charcoal lighter fluid or dropped into an ultrasonic cleaner. Should the situation require, they can be completely disassembled according to the Jewell Trigger Manual.
We ran into a situation where we had to dissemble a trigger due to the entrapment of some sticky dirt that couldn’t be removed with an ultrasonic cleaner. Our first step was to find some step-by-step instructions but we couldn’t find anything.
Recognizing that other shooters might be in the same situation we produced a step-by-step guide and video, published in full on 65Guys.com. These instructions will work with a left- or right-handed trigger. In our case we worked with a left-handed BR model trigger with safety and bolt release.
Step-by-Step Instructions are provided on 65Guys.com website. We recommend you read all the instructions carefully before you even think about disassembling your trigger. This video explains the process so you can get a sense of what is involved.

Here’s a simple task you can do that will give your seater die a more perfect fit to your match bullets. You can lap the inside of the seater stem so that it matches the exact profile of the bullet. This spreads out the seating force over a larger area of the bullet jacket. That allows smoother, more consistent seating, without putting dents, creases, or sharp rings in your bullets.
This process is demonstrated here by our friend Erik Cortina of Team Lapua-Brux-Borden. Erik, one of the nation’s top F-Class shooters and a skilled machinist, explains: “Here I’m lapping my new seater die stem with lapping compound. I chuck up a bullet in the lathe and lap the inside of the seating stem. I put lapping compound on the bullet and also in the stem. You can do the same with a hand drill and bore paste. You can see in the piture below how much contact area the stem has on the bullet after being lapped. This bullet is a Berger 7mm 180-grain Hybrid. ”
It can be helpful but it’s not necessary to make your seating stem an exact match to a bullet, particularly if you’re loading hunting or varmint rounds. But it is helpful to do some mild internal stem polishing. This should eliminate any ring (or dent) that forms on the bullet jacket during seating.
Sharp edges on a seating stem can cause a ring to be pressed into the bullet jacket — especially with compressed loads that resist downward bullet movement.
Q2: Is there any down-side to the process?
Not really. However, if you shoot many different bullet types for a particular cartridge, you may not want to conform the stem aggressively to one particular bullet design. Lightly lap the inside of the stem to remove burrs/sharp edges but leave it at that. A light lap will prevent a ring forming when seating bullets.
Savage Arms offers a series of Shooting Tips in the Savage Blog. Here is a helpful article from Team Savage Shooter Stan Pate. This covers how to ship your rifle safely, and then re-establish zero properly when the gun is reassembled after transport.
Traveling with Firearms — Important Advice
Traveling with firearms can be stressful. You must comply with multiple regulations and then trust your expensive guns to airline baggage handlers. And after arrival you’ll need to put your rifles back together and confirm the zeros. This article offers helpful travel advice from Team Savage shooter Stan Pate. Pate has traveled the globe competing with match rifles. Here he shares his tips for making trips easier on you and your firearms.
Easier Air Travel With Firearms
TSA isn’t nearly as careful with your rifles as you are. Proper storage before sending your firearm up a conveyer belt and into the belly of a plane is critical. Stan Pate spends lots of time each year traveling the skies and has devised a system for keeping his rifle safe when going to and from.
“Never travel with your firearm completely assembled,” Pate cautions. “A fully assembled firearm is much heavier [as a total unit] than one that has been broken-down and stored [in separate sections]. More weight creates more in-the-case movement, which can result in damage. I learned this the hard way years ago. My rifle was actually broken in half when traveling to an international competition. Record your torque settings, use those settings during reassembly and your return to zero should be no problem.”
“Be sure to check on current TSA rules and regulations before travel to be aware of any changes that may effect how you pack your rifles,” says Pate.
Rifle Reassembly and Resetting Zero
The quicker you can reestablish your zero, the quicker you can relax and stop worrying about if your rounds are going to hit their mark during competition. Pate, over the years, has developed a system for rifle reassembly and getting back to zero as quickly as possible. While his torque settings may not be the same as yours, the process can still be used.
“The barreled-action goes back on the stock, and then I tighten all three receiver screws finger tight,” says Pate. “Next, I tighten the front two receiver screws down to 35-inch pounds. The rear receiver screws on this particular rifle likes 15-inch pounds. [Note: Proper torque settings will vary with your action and stock type. Most actions have TWO screws, not three.] Scope attachment comes next, and I follow manufacturer settings when tightening it down. All that’s left to do now is go zero your rifle.”

Here is the original Sierra manufacturing facility in Whittier, CA.
In August 22, 2017 Sierra Bullets was acquired by Clarus Corporation (NASDAQ: CLAR), a Utah-based holding company that also owns Black Diamond Equipment Ltd., makers of ski and mountain gear/apparel. Sierra remains one of America’s leading producers of bullets and loaded ammunition. This article covers Sierra’s notable history, and also reviews Sierra’s processes for crafting and testing bullets.
Sierra Bullets — How It Got Started
Report Based on Story by Carroll Pilant, Sierra Bullets Media Relations Manager
What became Sierra Bullets started in the late 1940s in a Quonset hut in California. In 1947, three aircraft machinists, Frank Snow, Jim Spivey, and Loren Harbor, rented machine space to produce rivets for aircraft along with fishing rod guides and rifle front sight ramps. In the post-WWII years, sport shooting was becoming hugely popular, but quality ammunition was in short supply. For shooting enthusiasts, reloading was the solution to the ammo supply shortage. Snow, Spivey, and Harbor recognized this, creating Sierra Bullets to help fill the void. Before long, they were selling a 53-grain match bullet to the Hollywood Gun Shop. These bullets are still in production today as the Sierra #1400 53-grain MatchKing.
A few years later, an accomplished competitive shooter named Martin Hull joined Sierra. Hull helped develop new bullet types and served as manager of Sierra’s ballistics laboratory for nearly 20 years. With Hull’s help, Sierra’s output grew rapidly. The California company outgrew several locations before it moved to a large facility in Santa Fe Springs, CA, in 1963.
New Owners and New President in the Late Sixties
In 1968, the Leisure Group bought Sierra Bullets. Other Leisure Group companies included Lyman Reloading, High Standard Manufacturing Company, Yard Man, Thompson Sprinkler Systems, Flexible Flyer Sleds, and Dodge Trophies (Which made the Oscar and Rose Bowl Game trophies).
Soon after purchasing Sierra, the Leisure Group hired Robert Hayden as President and General Manager. Hayden was a mechanical engineer who had worked for Remington Arms. Hayden remained the president of Sierra for 42 years, retiring in 2012 when Pat Daly became president.
Sierra Moves to Missouri
In 1990, Sierra relocated to Sedalia, Missouri, where the company remains today. Sierra Bullets now employs over 100 people including five full-time ballistic technicians who answer daily reloading and firearms questions by both phone and e-mail.
The Making of MatchKings — How Sierra Produces SMKs
All Sierra bullets begin life as a strip of gilding metal, an alloy consisting of 95% copper and 5% zinc. To meet Sierra’s strict quality requirements, the gilding metal requires three times more dimensional and quality control standards than is considered standard in the copper manufacturing industry.
A blanking press stamps out a uniform disc and forms the cup that will be drawn into the MatchKing jacket. The cup is then polished and sent to a draw press to be drawn into a jacket that is longer than needed for the future MatchKing, thus allowing for the trim process. Press operators constantly check concentricity to make sure we have only quality jackets. The jackets then go to a trimmer where they are visually inspected again.
After being polished a second time, the jacket travels to the bullet press. In the meantime, 80-pound lead billets are being extruded into lead wire for the cores where great care is taken so that the core wire is not stretched. The core wire is lightly oiled before continuing to the bullet press to be swaged.
The lead core wire and trimmed jacket meet at the bullet press where the first stage forms a boattail on the jacket. The lead core is then formed on top of the bullet press and fed down into the jacket. In one stroke of the press, the MatchKing is formed.
Quality control technicians pull samples from each lot of MatchKings to make sure they meet Sierra’s stringent standards. Samples are then sent to Sierra’s 300-meter underground test range (shown below) to be shot for accuracy on mechanical mounts referred to as “unrestricted return to battery rests” that Sierra designed and built in-house.
After inspection, the bullets are placed in the familiar green box along with reloading labels. They are then shrink-wrapped and shipped all over the world.
Sierra Factory Ammunition with Modern Tipped Bullets
Sierra also produces popular competition and hunting factory ammunition. Sierra’s modern GameChanger hunting ammunition has shown very good performance and consistency. For the GameChanger line, Sierra re-engineered its MatchKing bullet into a hollow point design for quick expansion and fitted it with a green tip for ballistic uniformity. The lead-core GameChanger bullets deliver excellent penetration and expansion at a variety of ranges.

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.
Primer Functionality and Primer Types Compared
This video looks at a variety of primer types from multiple manufacturers, foreign and domestic. The video explains the basics of how primers function, and then explains the key characteristics of standard primers, magnum primers, and mil-spec primers (designed for semi-auto rifles).

For affordable, low-recoil shooting fun it’s hard to beat a semi-auto .22 LR. While Ruger’s 10/22 is the most popular semi-auto .22 LR rifle, many manufacturers are now offering AR-style self-loading rimfire rifles. We like AR-style .22 LR rigs for Rimfire Tactical Matches and 3-Gun cross-training. With an AR-style rimfire rifle you can train with low-cost ammunition while enjoying the same ergonomics, controls, and sighting systems found on your centerfire ARs.
If you shoot service rifle, and want to train at a fraction of the cost of shooting centerfire, a rimfire AR clone makes sense. This allows you to practice with a rifle with the same feel, balance, and ergonomics of your .223 Rem/5.56×45 service rifle.
These rimfire versions of the AR-15 are excellent training tools for 3-Gun and tactical match shooters. You can practice with less expensive rimfire ammo, and save wear and tear on your centerfire ARs. Rimfire AR clones also work great for Rimfire Tactical Matches.
Below we feature a variety of popular .22 LR rimfire AR-style rifles, including the Smith & Wesson M&P 15-22, the Tippman Arms series of rimfire ARs, and the HK 416 marketed by Walther.
Smith & Wesson M&P 15-22
Smith & Wesson has upgraded its M&P 15-22, a fun rifle that we’ve praised in the past. The latest M&P 15-22 Sport MOE SL model (Magpul Original Equipment Slim Line) features a more comfortable handguard, an improved grip, and an adjustable Magpul buttstock. The dedicated .22 LR M&P rifle retains the look and features of the company’s popular M&P rifle line, with the enhanced ergonomics of Magpul furniture. It’s offered with Flat Dark Earth (tan) furniture or dressed in matte black.
Field Testing the Smith & Wesson M&P 15-22
Smith & Wesson’s 15-22 is a nice little rifle. The M&P 15-22 is designed and built as a true .22 LR semi-auto from the ground up, with ergonomics (and most controls) identical to a centerfire M&P 15 rifle. NRA reviewer Colon Noir tested the M&P 15-22 and was impressed: “This gun is unbelievably fun to shoot. There is virtually no recoil. The non-existent recoil makes shooting fast a breeze. Yeah, the magazine is a little quirky… but in the grand scheme of things, this gun feels like a full-out AR-15. The M&P 15-22 makes for a great training companion. I would place this gun in the ‘Fun Box’ — it’s reliable enough that you can have a fun time shooting. I’m picking one up, because it’s guns like these that make you truly realize how fun shooting is.”
Here’s a Video Review of the M&P 15-22 by the NRA’s Colin Noir
Tippmann Arms .22 LR AR-Type Rifles
Tippmann Arms makes a large variety of AR-15 style rimfire rifles. Tippmann also offers “house-brand” .22 LR magazines that work great with virtually all .22 LR ammunition — even the low-cost bulk ammo. To learn more, watch the videos below, which demonstrate the excellent functionality and reliability of the Tippmann AR clones. We also recommend the Shooting Sports USA Review of the Tippman Arms M4.
Owners have been very impressed with these Tippmann .22 LR semi-auto rifles. They are very reliable and have ergonomics/layout identical to a centerfire AR15. That makes them ideal for cross-training. Here are comments from some Tippman .22 LR rifle owners:
“Wanted a dedicated .22 LR to shoot with my 22 suppressor. I have a CMMG .22 LR conversion for use in my ARs. I just didn’t like ‘dirtying’ up my regular ARs shooting rimfire. So I bought the Tippmann. Very impressed with the gun. Runs well, and great quality. And I hear they have great customer service. And unlike some other “22LR” ARs, the Tippman is identical to a regular AR as far as controls, feel, and operation. Great for training, or plinking!”
“The wife and I have been running a Tippmann Redline in matches for a year now. Great rifle and company. Picked-up one of the speedloaders last fall and it makes a huge difference in both speed and comfort. No more sore thumb syndrome from loading those 25-round mags.”

Many novice hand-loaders believe that neck bushing Inside Diameter (ID) size is the only important factor in neck tension. In fact, many different things will influence the grip on your bullet and its ability to release from the case neck. To learn more about neck tension and “case grip”, take the time to read this article carefully. We bet you’ll gain knowledge that will let you load more accurate ammo, with better ES/SD.
Editor: Guys, this is a VERY important article. You really should read it over carefully, twice. Variations in the force required to release a bullet can significantly affect accuracy and ES/SD. You really need to know how the grip on bullet can be altered by many different factors.
Neck Tension (i.e. Grip on Bullets) Is a Complex Phenomenon
While we certainly have considerable control over neck tension by using tighter or looser bushings (with smaller or bigger Inside Diameters), bushing size is only one factor at work. It’s important to understand the multiple factors that can increase or decrease the resistance to bullet release. Think in terms of overall brass-on-bullet “grip” instead of just bushing size (or the internal neck diameter in non-bushing full-length sizing dies).
Bullet grip is affected by many things, such as:
1. Neck-wall thickness.
2. Amount of bullet bearing surface (shank) in the neck.
3. Surface condition inside of neck (residual carbon can act as a lubricant; ultrasonic cleaning makes necks “grabby”).
4. Length of neck (e.g. 6mmBR neck vs. 6mm Dasher).
5. Whether or not the bullets have an anti-friction coating.
6. The springiness of the brass (which is related to degree of work-hardening; number of firings etc.)
7. The bullet jacket material.
8. The outside diameter of the bullet and whether it has a pressure ridge.
9. Time duration between bullet seating and firing (necks can stiffen with time).
10. How often the brass is annealed.
11. Amount (length) of neck sized (e.g. you can size only half the neck).
12. Interior diameter of bushing, or neck section of non-bushing die. – and there are others…
One needs to understand that bushing size isn’t the beginning and end of neck tension questions, because, even if bushing size is held constant, the amount of bullet “grip” can change dramatically as the condition of your brass changes. Bullet “grip” can also change if you alter your seating depth, and it can even change if you ultrasonically clean your cases.
6-time U.S. National Long-Range Champion John Whidden adds: “Our tests show us that the condition of the necks in regards to lubed or not, carbon inside or not, squeaky clean or not, etc., matter even more than the size of the bushing used. An ultrasonically cleaned or brand new dry case neck make for some quite high seating force.”
In our Shooters’ Forum a reader asked: “How much neck tension should I use?” This prompted a lengthy Forum discussion in which other Forum members recommended a specific number based on their experience, such as .001″, .002″, or .003″. These numbers, as commonly used, correspond to the difference between case-neck OD after sizing and the neck OD of a loaded round, with bullet in place. In other words, the numbers refer to the nominal amount of interference fit (after sizing).
While these commonly-used “tension numbers” (of .001″, .002″ etc.) can be useful as starting points, neck tension is actually a fairly complex subject. The actual amount of “grip” on the bullet is a function of many factors, of which neck-OD reduction during sizing is just one. Understanding these many factors will help you maintain consistent neck tension as your brass “evolves” over the course of multiple reloadings.
Seating Depth Changes Can Increase or Decrease Grip on Bullet
You can do this simple experiment. Seat a boat-tail bullet in your sized neck with .150″ of bearing surface (shank) in the neck. Now remove the bullet with an impact hammer. Next, take another identical bullet and seat it with .300″ of bearing surface in another sized case (same bushing size/same nominal tension). You’ll find the deeper-seated bullet is gripped much harder.
Neck-Wall Thickness is Important Too
I have also found that thinner necks, particularly the very thin necks used by many 6mm PPC benchrest shooters, require more sizing to give equivalent “grip”. Again, do your own experiment. Seat a bullet in a case turned to .008″ neckwall thickness and sized down .003″. Now compare that to a case with .014″ neckwall thickness and sized down .0015″. You may find that the bullet in the thin necks actually pulls out easier, though it supposedly has more “neck tension”, if one were to consider bushing size alone.
In practical terms, because thick necks are less elastic than very thin necks, when you turn necks you may need to run tighter bushings to maintain the same amount of actual grip on the bullets (as compared to no-turn brass). Consequently, I suspect the guys using .0015″ “tension” on no-turn brass may be a lot closer to the guys using .003″ “tension” on turned necks than either group may realize.
Toward a Better Definition of Neck Tension
As a convenient short-cut, we tend to describe neck tension by bushing size alone. When a guy says, “I run .002 neck tension”, that normally means he is using a die/bushing that sizes the necks .002″ smaller than a loaded round. Well we know something about his post-sizing neck OD, but do we really have a reliable idea about how much force is required to release his bullets? Maybe not… This use of the term “neck tension” when we are really only describing the amount of neck diameter reduction with a die/bushing is really kind of incomplete.
My point here is that it is overly simplistic to ask, “should I load with .001 tension or .003?” In reality, an .001″ reduction (after springback) on a thick neck might provide MORE “grip” on a deep-seated bullet than an .003″ reduction on a very thin-walled neck holding a bullet with minimal bearing surface in the neck. Bushing ID is something we can easily measure and verify. We use bushing size as a descriptor of neck tension because it is convenient and because the other important factors are hard to quantify. But those factors shouldn’t be ignored if you want to maintain consistent neck tension for optimal accuracy.
Consistency and accuracy — that’s really what this all about isn’t it? We want to find the best neck tension for accuracy, and then maintain that amount of grip-on-bullet over time. To do that you need to look not only at your bushing size, but also at how your brass has changed (work-hardened) with time, and whether other variables (such as the amount of carbon in the neck) have changed. Ultimately, optimal neck tension must be ascertained experimentally. You have to go out and test empirically to see what works, in YOUR rifle, with YOUR bullets and YOUR brass. And you may have to change the nominal tension setting (i.e. bushing size) as your brass work-hardens or IF YOU CHANGE SEATING DEPTHS.
Remember that bushing size alone does not tell us all we need to know about the neck’s true “holding power” on a bullet, or the energy required for bullet release. True bullet grip is a more complicated phenomenon, one that is affected by numerous factors, some of which are very hard to quantify.

When you stack a column of primers in a single metal tube, you’re asking for trouble. As Dustin Ellermann learned, when one primer fires, the entire column can follow suit in a chain detonation. Thankfully, you do have options when it comes to primer feeding on a progressive press. RCBS developed an innovative, smart system with primers in horizontal plastic strips. Instead of being stored in a vertical tube, primers are placed in flat, plastic “APS” strips, with a ring of plastic separating each primer. Moving horizontally, primers are never stacked, so the chance of a chain detonation is reduced dramatically. The re-usable APS strips are color-coded for different primer types. You can buy CCI “pre-loaded” primer strips, or you can insert any brand of primers into strips using an RCBS strip-loader tool.
