22Plinkster Tours CCI/Speer Idaho Factory
Trickshot artist and YouTube host 22Plinkster recently got a chance to tour the CCI/Speer production facility in Lewiston, Idaho. This large plant produces both rimfire and centerfire ammunition. While touring the plant, 22Plinkster was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching.
This revealing video shows all phases of .22 LR ammo production including cupping, drawing, annealing, washing, drying, head-stamping, priming, powder charging, bullet seating, crimping, waxing, inspection, and final packaging. If you’ve got ten minutes to spare, we really recommend you watch the video from start to finish. You’ll definitely learn some new things about rimfire ammo.
.22 Plinkster was literally up to his neck in ammo while touring the CCI/Speer Idaho ammo plant. He says: “This was truly a dream come true for me. I can’t thank the people at CCI and Speer enough for allowing me to do this. I couldn’t possibly show everything that went on at the factory. However, hopefully I showed you enough for you to grasp the concept of how rimfire [ammo] is made.”
Speer Brothers Brought Ammo Production to Lewiston
Here is an interesting historical footnote. Today’s large CCI/Speer operation in Idaho can be traced back to the companies founded by the Speer brothers. After settling in Lewiston in 1944, Vernon Speer started Speer Bullets. A few years later, in 1951, Vernon’s brother Dick (with partner Arvid Nelson) started Cascade Cartridges Inc., a producer of small-arms ammunition and primers. Yes, as you may suspect, Cascade Cartridges Inc. is now CCI, a Vista Outdoor company, and one of the largest manufacturers of primers and loaded ammunition. Today, the CCI/Speer Lewiston plant produces both Speer bullets and CCI-branded ammunition and primers. Vista Outdoor’s predecessor, ATK, acquired the plant in 2001. Vernon Speer died in 1979, and Dick Speer died in 1994.
Quadruple Distinguished Marksman
You are looking at a very special human being — the world’s only holder of FOUR Distinguished Marksmanship Badges. While competing in the 2016 National Trophy Pistol Matches at Camp Perry, Team Lapua’s Steve Reiter (Tucson, AZ) became the first Quadruple Distinguished Badge Marksman in history. This past week, 74-year-old Reiter received his most recent Distinguished Badge, the new .22 Rimfire Pistol Badge, which has only been in existence since 2015. Before that, Reiter had earned his Pistol Distinguished Badge in 1972, his International Badge in 1973, and his Rifle Distinguished Badge in 1998. Over his four-decade competitive career, Reiter has competed in free pistol, standard pistol, air pistol, and centerfire events as well as rifle.
Earning FOUR Distinguished Badges is a great achievement — something that has never been done before, much less by a Senior shooter. We offer our congratulations to Steve for achieving this first-ever, shooting milestone.
Practice and Hard Work Were Key Says Reiter
Reiter told us: “It’s a big honor, really. When you’re the first at anything, it’s a big honor. It feels great to be the first.” Steve added: “Most people don’t understand how much work it is. And it being a CMP badge … it means something.”
To be a successful marksman, Steve explained, it takes dedication and lots of practice: “You have to work pretty hard. More or less, you have to do a lot of practicing and a lot of dry-firing, and actually work at it. You can’t come out here and just shoot. You’ve got to really work at it, like anything else, to get to the top of your field.”
A former U.S. Army Reserve Team member, Reiter’s list of shooting honors over his 40-year competition career is truly remarkable:
Member of the 1980 Olympic team in Free Pistol
Five-time National Champion at Camp Perry
34 Overall National Championship Titles
44 National Records
40+ Regional Championships
Two-time President’s 100 Champion in Pistol
Two-time National Trophy Individual Match Champion in Pistol
10-time Winner of the National Match High Senior Pistol Trophy
Five-time Winner of Citizens’ Military Pistol Trophy
Canada International Service Pistol Champion
Two-time Free Pistol National Champion
Standard Pistol National Champion
Seven-time Interservice Championship Team Member
In addition to these titles, Reiter also set other numerical scoring records, including the best .22 Aggregate (899), and the best Three-Gun Aggregate Score (2671).

Are we seeing an end to the “desperate days” for .22 LR rimfire ammo? Are supplies finally starting to catch up to demand? At least one industry analyst thinks so. Gun journalist Dean Weingarten has been watching trends. Makers of .22 LR ammo have increased production by 20%. That’s a good thing. We are starting to see the effects, Dean observes, with increased supplies and falling prices for rimfire ammo. Here is Dean’s report from Arizona.
I chanced to be at the local WalMart in Yuma, Arizona today (July 8, 2016). This is the store on the frontage road off of old Highway 8, East of town. Until Friday, June 24, 2016, I had not seen any .22 Long Rifle in the store for three years.
On that date, there were 2,300 rounds of CCI Mini-Mags and 1,000 rounds of CCI Standard Velocity. The Mini-Mags were in plastic 100-round boxes at $7.47 a box. The Standard Velocity were in paper, 50-round boxes at $3.47 a box.
Just 10 days later, on the 3rd of July, I was in the same store, and there were 1900 rounds of CCI Stinger, in 50-round boxes. It is premium .22 Long Rifle ammunition, and has always been pricey. The price was $6.47 for a box of 50, or a little under 13 cents a round. They also had CCI .22 Maxi-Mag, .22 magnum rimfire cartridges, for $13.47 a box of 50, or nearly 27 cents a cartridge. It has been scarce, but not as bad as the .22 Long Rifle.
Two sightings in 10 days after three years was remarkable.
.22 LR Ammo for 5.36 Cents Per Round
Today, the 8th of July, there were two cases of bulk pack Federal .22 Auto Match. That is 6,500 .22 Long Rifle cartridges.This is only five days after the previous sighting. The boxes contained 325 cartridges. [The clerk] was just opening the cases to stock the shelves when I showed up. She said there had been a couple of bricks of .22, but they had been purchased immediately.
At $17.42 for 325 rounds of Auto Match .22, that is 5.36 cents per round. A little over two years ago, I wrote that the .22 ammunition bubble would be over when you saw .22 LR ammunition on sale below 4 cents a round:
“You will know that the bubble is close to the bottom when you see .22 LR on sale for below 4 cents per round. At the lowest, we might see .22 LR cartridges below $10 for 500.”Read Article from 6/7/2014.
Many dismissed my prediction. They said that we would never see .22 cartridges below 4 cents a round again. People said that I was crazy when gasoline was at $4 a gallon, and I wrote that we would see it below $2 in the future. It went below $2 a few months ago.
The .22 ammunition bubble is hanging on. The push for more Second Amendment infringements by the Obama administration keeps it inflated. But with only six months to go to the end of that administration, the bubble has become fragile. The .22 ammunition manufacturers have increased production by 20%. That puts a lot of strain on the bubble.
Here’s a useful, cost-efficient product if you have a rifle with a 3/8″ dovetail on top of the action and you want to use a scope with Weaver-style rings. Kwik-Site offers three grooved receiver adapter products. The first is a two-piece set of short rails that clamp to a 3/8″-wide dovetail. Priced at just $13.50, this two-piece rail set, item KS-W22, is available in gloss black, matte black, and a stainless finish. If you prefer a one-piece rail, Kwik-Site offers the KS-W23 ($29.95) and KS-W24 ($30.95). Both are offered in matte black or silver (stainless-look) finishes. The KS-W24 will work with Romanian rifles.
These Kwik-Site products provide a low-cost solution if you want to take a scope from a rifle with a Weaver Rail and place the optic on a dove-tailed action without removing the scope from the ring set. Please note however, you’ll still need to re-zero the scope when you move it from one rifle to another. To order online, visit www.KwikSitecorp.com.

AUDIO FILE: Bryan Litz Talks about Modern Advancements in Long Range Shooting, Volume 2. (Sound file loads when you click button).
Volume II of Modern Advancements in Long Range Shooting contains all-new content derived from research by Applied Ballistics. Author Bryan Litz along with contributing authors Nick Vitalbo and Cal Zant use the scientific method and careful testing to answer important questions faced by long range shooters. In particular, this volume explores the subject of bullet dispersion including group convergence. Advanced hand-loading subjects are covered such as: bullet pointing and trimming, powder measurement, flash hole deburring, neck tension, and fill ratio. Each topic is explored with extensive live fire testing, and the resulting information helps to guide hand loaders in a deliberate path to success. The current bullet library of measured G1 and G7 ballistic coefficients is included as an appendix. This library currently has data on 533 bullets in common use by long range shooters.
Bryan tells us that one purpose of this book is to dispel myths and correct commonly-held misconceptions: “Modern Advancements in Long Range Shooting aims to end the misinformation which is so prevalent in long range shooting. By applying the scientific method and taking a Myth Buster approach, the state of the art is advanced….”
Bullet Dispersion and Group Convergence
Part 1 of this Volume is focused on the details of rifle bullet dispersion. Chapter 1 builds a discussion of dispersion and precision that every shooter will benefit from in terms of understanding how it impacts their particular shooting application. How many shots should you shoot in a group? What kind of 5-shot 100 yard groups correlate to average or winning precision levels in 1000 yard F-Class shooting?
Chapter 2 presents a very detailed investigation of the mysterious concept of group convergence, which is the common idea that some guns can shoot smaller (MOA) groups at longer ranges. This concept is thoroughly tested with extensive live fire, and the results answer a very important question that has baffled shooters for many generations.
Part 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.
One of the important chapters of Part 2 examines bullet pointing and trimming. Applied Ballistics tested 39 different bullet types from .224 through .338 caliber. Ten samples of each bullet were tested for BC in each of the following configurations: original out of the box, pointed, trimmed, pointed and trimmed. The effect on the average BC as well as the uniformity in BC was measured and tabulated, revealing what works best.
Part 3 covers a variety of general research topics. Contributing author Nick Vitalbo, a laser technology expert, tested 22 different laser rangefinders. Nick’s material on rangefinder performance is a landmark piece of work. Nick shows how shooters can determine the performance of a rangefinder under various lighting conditions, target sizes, and reflectivities.
Chapter 9 is a thorough analysis of rimfire ammunition. Ballistic Performance of Rifle Bullets, 2nd Edition presented live fire data on 95 different types of .22 rimfire ammunition, each tested in five different barrels having various lengths and twist rates. Where that book just presented the data, Chapter 9 of this book offers detailed analysis of all the test results and shows what properties of rimfire ammunition are favorable, and how the BCs, muzzle velocities and consistency of the ammo are affected by the different barrels.
Chapter 10 is a discussion of aerodynamic drag as it relates to ballistic trajectory modeling. You will learn from the ground up: what an aerodynamic drag model is, how it’s measure and used to predict trajectories. Analysis is presented which shows how the best trajectory models compare to actual measured drop in the real world.
Finally, contributing author Cal Zant of the Precision Rifle Blog presents a study of modern carbon fiber-wrapped barrels in Chapter 11. The science and technology of these modern rifle barrels is discussed, and then everything from point of impact shift to group sizes are compared for several samples of each type of barrel including standard steel barrels.
We really like rimfire revolvers here at AccurateShooter.com. A good .22 LR wheelgun will be fun, accurate, reliable, and inexpensive to shoot. Rimfire revolvers also offer much less recoil and noise than a centerfire pistol. Your Editor has owned a Smith & Wesson Model 617 for over 15 years. That old S&W has probably fired more rounds than all the other handguns I own, combined — yet it still runs flawlessly and still delivers excellent accuracy.
Ruger recently came out with a new, stainless .22 LR wheelgun to compete with the S&W Model 617. This new rimfire wheelgun is based on Ruger’s trusted GP100 platform. The new Ruger® GP100® chambered in .22 LR looks to be a good firearm — strong, versatile, and intelligently engineered. In the video above, Jeff Quinn of Gunblast.com tests the Ruger revolver and gives it high marks: “It’s a good hefty gun [42.6 oz.], but not overly large or heavy for a good trail gun. It’s just a really nice, well-made revolver from Sturm Ruger.” The gun Jeff tested had a 3.7-lb SA trigger pull and a 9.8-lb DA pull.
The .22 LR GP100 features a windage and elevation adjustable rear sight with a white outline, a light-gathering fiber optic front sight and the original full-size GP100 rubber grips with hardwood inserts. With all stainless-steel construction, the rimfire GP100 is easy to maintain. Just keep the cylinder chambers and barrel clean and this gun should run forever.
The 10-shot Ruger GP100 in .22 LR is a durable, well-engineered wheelgun. Ruger’s engineers optimized the GP100’s innards to deliver a smooth double-action pull: “The new GP100 has an improved fire-control system that uses a lighter mainspring than previous Ruger double-action .22 LR revolvers. A number of changes have been made to the GP100 to handle .22. One of which is we’ve done a lot of development on the firing pin location and geometries so that we’re able to put a lighter trigger pull in this gun than you would find in other .22 LR [handguns]. We’ve got a half-underlug barrel, and it’s a smaller diameter so the gun balances real well. We’ve added a narrow-spur hammer and a smooth trigger for comfortable shooting. This is a really comfortable gun to shoot”.
Report based on story byNRABlog.com
Starting this summer, the NRA National Smallbore Rifle Championships will no longer feature a separate “High Women” award. From now on, men and women will compete shoulder to shoulder in the same category — every shooter will be scored in a single group regardless of gender. (There will still be age-based categories; also men and women have always been eligible to win match top honors regardless of gender).
The reason for this change is, quite simply, that ladies can shoot as well as men (or better in many cases). Consequently, there is no need for a separate class for women: “There is a high degree of parity between men and women shooters in the smallbore championships,” said H.Q. Moody, national manager of NRA’s Rifle Department. Moody explained: “Women are rightly viewed as equals in today’s America. Shouldn’t our championships reflect that attitude as well? Our smallbore committee has discussed making the championships gender equitable for many years now and finally felt it was the right time to implement the change.”
Men and women will now compete on equal terms at the National Smallbore Championship, competing for the same honors in “gender-neutral” classifications. Photo courtesy Shooting Sports USA.
This change was officially adopted this past January at the NRA Board of Directors winter meetings. It only affects the NRA National Smallbore Rifle Championships for now, but a positive reception could see “gender-neutrality” spread to regional matches and below, and maybe even other NRA disciplines.
History of Women’s Classfication in Smallbore Competition
The women’s category was first introduced to the smallbore championships nearly 70 years ago. Back then, military shooters were dominating the field so convincingly that several new categories were created to recognize the accomplishments of civilian shooters. This move saw the creation of not just the Woman category, but also Junior and Senior. The latter two have since expanded even further (e.g. Grand Senior, Intermediate Junior) to accommodate the skill discrepancies within levels and they make perfect sense to have; junior shooters are generally more inexperienced and many seniors are affected by physical limitations.
But the same can no longer be said of the women’s category. While military shooters still do very well nowadays, the proliferation of female service members has seen quite a few woman match winners. There are also a number of extraordinary female civilian shooters who finish near the top of each year’s overall standings. For instance, women shooters placed first in each of the two aggregate matches that determined last year’s Conventional 3-Position Champion.
The 2016 Berger Southwest Nationals event is less than a week away. If you need some last-minute practice before this match and you don’t have the time (or money) to load a couple hundred rounds of centerfire ammo, consider rimfire practice. Past F-TR National Champion James Crofts attributes much of his success to plenty of trigger time with his rimfire training rifle.
Rimfire Training for F-Classers
2014 and 2012 U.S. National F-TR Champion James Crofts is one of America’s top F-Class shooters. A member of the 2013 World Championship-winning F-TR Team USA squad, James knows a thing or two about long-range shooting, that’s for sure. But you may be surprised to learn how James sharpens his shooting skills at relatively short distances. You see, James often practices with a .22 LR rimfire rifle at distances from 50 to 200 yards. James tells us: “Shooting my F-Class rimfire trainer saves me money and improves my shot process and wind-reading abilities.”

Rimfire Training Teaches Wind-Reading Skillsby James Crofts
Training with the rimfire is extremely useful and can be done from 25 yards out to 200 yards. I am lucky and can shoot 50 yards right off my back deck. That is far enough that any miscue on rifle handling will show up on the target. I use a two dry-fire to one actual shot routine for my practices. This gives me much more positive reinforcement without any negative reinforcement.
Wind reading is extremely important with a .22 LR rifle. I use a set of smallbore flags to aid my wind calls. The smallbore flags are a must and force you to look at the flags and mirage on each and every shot. If you think the flags at Camp Butner move a lot, try smallbore flags around tall pine trees.

Rimfire Training Is Cost-Effective
Rimfire ammunition is much less costly than centerfire ammo. Though .22 LR prices have risen in recent years (and rimfire ammo is harder to find), even now I can get a 500-round brick of .22 LR ammo for less than $75.00. That works out to fifteen cents a round. That’s a fraction of the cost of handloading .308 Win match ammo. Heck, you can pay 40 cents a piece for match-grade .308-cal centerfire bullets. Then you have to figure in brass, primers, and powder.
My CMP 40X Rimfire F-TR LowBoy Clone
My quest into the .22 LLR rimfire field started with an email from the Civilian Marksmanship Program (CMP) announcing Rem 40X stripped barreled actions for sale. I thought, “Hmmm… Could one of those little 40X barreled actions be turned into a F-Class training rifle?” My gunsmith Ray Bowman of Precision Rifle & Tool was brought in at this point.
After conferring with Ray, it was decided that he could indeed turn this into a F-Class training rifle. Ray contacted Dave Kiff of PT&G and ordered a new bolt for the Remington 40X rimfire action. Next was the stock decision. I decided to go with a PR&T Low Boy F-Class stock — this is an exact clone of the stock for my .308 Win F-TR competition rifle. Then a Jewell trigger was acquired to complete the components. Ray built this just like he would any custom rifle, other than using the stock barrel. The project turned out awesome. The rifle was a hammer from the beginning even with the stock barrel.
