CFIUS Clears Sale of The Kinetic Group to CSG
Vista Outdoor Inc. (NYSE: VSTO) and Czechoslovak Group a.s. (“CSG”) have announced that the Committee on Foreign Investment in the United States (“CFIUS”) has cleared CSG’s proposed acquisition of Vista Outdoor’s The Kinetic Group business. CFIUS has concluded its investigation of the Transaction and has determined that there are no unresolved national security concerns. CFIUS clearance was the final regulatory approval required under the merger agreement with CSG. CFIUS is a U.S. government committee that reviews foreign investment transactions to determine their effect on U.S. national security.

The Shooting Wire reports: “Vista Outdoor Inc. cleared a major hurdle in its plans to sell off its ammunition segment, known as The Kinetic Group, to Czechoslovak Group, or CSG, after the Committee on Foreign Investment in the United States (CFIUS) cleared the proposed acquisition of The Kinetic Group business after the Committee determined ‘there are no unresolved national security concerns’. The closing of the transaction remains subject to receipt of the approval of Vista Outdoor’s stockholders[.] The Vista Board recommends stockholder approval based partly on a $2 billion purchase price, representing a $90 million increase from the original $1.91 billion purchase price.”

Michael Callahan, Chairman of the VSTO Board of Directors stated: “The CFIUS process involved a thorough review and investigation of the Transaction by numerous U.S. Government departments and agencies[.] We believe the end result supports our view that CSG — which has deep expertise in supply chain excellence and ammunition manufacturing and strong support for NATO and allied nations — will be an excellent owner of The Kinetic Group. CSG is fully committed to supporting our American workforce, American hunters, and domestic and allied military and law enforcement partners.”

The closing of the transaction remains subject to the approval of Vista Outdoor’s stockholders and other customary closing conditions. The special meeting of Vista Outdoor stockholders to vote on a proposal to adopt the merger agreement with CSG is scheduled to be held virtually on July 2, 2024, at 9:00 a.m. Central Time.

.243 Ackley Improved for Long-Range Varminting and Benchrest Competition
Whenever Matt Bianchini brings his bright yellow .243 Ackley to the firing line, heads turn. This is one truly handsome rig–as good-looking as it is accurate. Built to smoke varmints at long-range as well as compete in 1000-yard benchrest matches, this rifle is proof that competition improves the breed. Fitted with a Farley action, Jewell trigger, Leupold LRT scope, and Lilja or Krieger barrel, the Yellow Ackley is a “no compromise” match rifle that can run with the big dogs in 1K Benchrest competition. And with the Ackley’s ability to toss 106gr Clinch Rivers at 3350 fps, this is one flat-shooting, hard-hitting varmint rifle.

Ultra-Fast, Ultra-Smooth Farley Action…and One Wicked Paint Job
The heart of Matt’s rifle is a Farley action. Farleys have found favor with Benchrest competitors, because the bolt can be worked so fast. And the Farley is as smooth as it is speedy. The difference is quite noticeable if you compare it to a blue-printed Rem 700, or even a recent Stolle Panda. Farleys were true customs, built one at a time by the Farley family in Oklahoma. Unlike a BAT action which is machined from billet steel, a Farley starts with a stainless investment casting, much like Ruger pistol frames. It uses a cone bolt for smooth, yet solid lock-up.

One of the unique features of the Farley is the ejector–it can be switched on or off, depending on the shooter’s preference. So, if you’re load testing some hot rounds, you can turn the ejector off. In a match you can turn the ejector “on” to function normally. Matt is now a confirmed Farley fanatic. He tells us: “I’ve got quite a few other very nice actions, including Nesikas. But none of them are as slick as that Farley. When you work the bolt it feels like it’s on ball-bearings.”

Matt’s Screamin’ Yellow Ackley–The Need for Speed .243 Ackley Improved Speed Demon In a long-range varmint rifle, speed kills. Ultra-high velocities will deliver flatter trajectories and more explosive hits on critters. That’s where the .243 Ackley Improved really shines. Matt has explored the upper limits of .243 Ackley Improved (AI) performance with his yellow long-range rig, fitted with a 29″ Lilja 3-groove, 1:8″-twist barrel. Using a stout load of Alliant Reloder 25, Matt’s “Screamin’ Yellow Ackley” has topped 3340 fps with Clinch River 106s. That’s serious speed for heavy 6mm bullets. This shows a well-built .243 AI leaves Dashers and 6XCs in the dust when it comes to pure velocity.

Ultimate Evolution of the .243 Winchester
Matt’s show-stopping rifle is a .243 Ackley Improved (40-degree shoulder, .271″ neck), chambered with a Manson reamer. On top of the stainless Farley “S” action, in Farley 30mm rings, sits a Leupold LRT (1/16 MOA dot) boosted to 18X-40X by Premier Reticles. Matt has SIX barrels for the gun, three Lilja 3-grooves, a couple Kriegers, and a Shilen.

Matt’s gun currently sports an 8-twist 29″ Lilja 3-groove HV taper that Matt says cleans up like a dream. The stock is a Shehane ST-1000 Tracker made in fiberglass by McMillan, with a BAT trigger guard and Shehane polished billet aluminum buttplate. Prior to final finishing, Matt worked over the flats and some of the angles. That’s why the facets are so well-defined on this rifle compared to some ‘glass Trackers you may have seen. The gun was chambered by Dave Bruno of Cheswick, PA.

Matt bedded the stock and applied the stunning Sikken “Viper” yellow paint job himself. That flawless, smooth-as-glass Screamin’ Yellow finish is no ordinary paint-job, but then Matt Bianchini is no ordinary do-it-yourself painter. His family runs an automotive body-shop, so he had access to premium paints and a quarter-million-dollar spray booth with all the latest technology. Still, Matt spent many hours on this stock to get everything right, trying a couple colors before he settled on a Sikken automotive “Viper Race Yellow” formulated for the Dodge Viper sports car. After careful prep work, Matt sprayed two coats of Viper Yellow, and then added three coats of high-grade automotive clear, which was then baked-on in a heat chamber. Matt also painted the Sinclair front rest to match the stock, and even polished the surfaces of the Hoehn windage top. A lot of effort, Matt told us, was required to achieve the results you see here.

3300 fps for 1000 Yards Though Matt’s Ackley has harvested its share of varmints, the gun was built with 1000-yard benchrest competition in mind. At left is the firing line at Thunder Valley, Ohio. Yep those targets (upper right) are 1000 yards away. Now you know why Matt has a 40-power scope. The Yellow Ackley weighs just under 17 pounds to meet IBS and NBRSA “Light Gun” weight limits. While Matt says his bullets don’t “go to sleep” for a couple hundred yards, this gun can still shoot 1/4″ groups at 100 yards and hold that accuracy much, much farther. Matt reports, “my best-ever group was five shots in .397″ at 400 yards. Yep, I got lucky with the conditions, but this is a very accurate rifle.”

Loading for Long-Range
For long-range shooting, Matt loads 106gr Clinch Rivers with 47.5gr of Alliant Reloder 25 for his Krieger barrels, a little more powder with the Lilja 3-grooves. The Lilja load runs 3342 fps, with a 3.228″ OAL. Cases are neck-turned Lapua .243 Winchester. He uses Wilson inline seater and Wilson eck-sizer dies (.267″ bushing), and a custom, reamer-cut FL sizing die.

Not Just for BR, This Gun Can Hunt
While Matt has a big stable of varmint rifles, the Yellow Ackley has seen plenty of duty in the ‘Hog fields. Matt is from a farming family and he can shoot practically right out his back door (see top photo at the farm). He has nailed some big ground-hogs at 800 yards and beyond. The .243 AI does kick a bit compared to other varmint cartridges, but even with 105-106gr bullets, it’s not bad. He has considered adding a muzzle brake at some point to one of the barrels, just so he can see impacts better.

Screamin’ Yellow Dasher? Matt originally thought of building the gun up as a 6BR or a 6BR Improved. He has a Manson reamer similar to a 6mm Dasher, with a 40-degree shoulder and .008″ body taper. He actually chambered a couple barrels with that 6BR Improved reamer, but he hasn’t shot them yet. He was so pleased with how the gun performed in .243 AI, that he saw no reason to change. And it may be a while before he slaps a Dasher-chambered barrel on the rig: “I really like the way it shoots as a .243 AI. I’m so impressed with it that I don’t want to mess with anything. And I don’t think I’ll be running out of Ackley barrels anytime soon.” Millender’s .243 Ackley Improved Page

.243 Win Dies and Reloading Gear

Since the .243 Win is such a popular cartridge, all the major die-makers offer reloading dies. It’s hard to go wrong with a Redding Type ‘S’ Full-length bushing die–item 77114 for the standard .243 Win and item 77420 for .243 AI. Whidden Gunworks also makes great .243 Win sizing dies (and custom .243 Win AI dies on request). These will both resize the case (and bump the shoulder) as necessary, and allow you to adjust neck tension with bushings. Alternatively, you can go with a body die, and a separate neck bushing die.

If you load primarily one brand of bullets, another slick set-up is to buy a Forster or Whidden full-length, non-bushing .243 Win sizing die, and then have Forster or Whidden hone the neck for your desired amount of tension. This elegant one-pass sizing solution produces very straight rounds with low run-out.

For bullet seating, both the Redding Competition Seater (item 55114) and the Forster Ultra-Seater (item U00034) work great for the standard .243 Win case. If you shoot a .243 Ackley, Redding’s .243 AI Comp Seater (item 55420) costs quite a bit more than the standard version Forster doesn’t list a .243 AI seater in their catalog. However, you can just run your chambering reamer into the inner sleeve of either seating die to fit the .243 Ackley Improved case.

If you want the “Cadillac” of production seater dies for the .243 Win, order the Wilson Stainless Micrometer seater (item 50-1114S) from Sinclair International. Costing only a few dollars more than a Redding Comp seater, this die is a joy to use, providing very positive control over bullet seating depth. When used with a quality arbor press, the Wilson offers unrivaled “feel” for bullet-seating force. This can help you monitor neck tension, one of the most critical factors in maintaining low ES and SD for long-range accuracy.

POWDER GRAIN SHAPES — What You Need to Know

The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).

All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.

Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.

Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.

The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.

The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.

So how does the shape affect pressure and muzzle velocity? In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.

Do you shoot a magnum cartridge? Here are two modern-formulation powders you may want to try: Reloder 23 and 26. We have been particularly impressed with Reloder 23. It has worked well in competition for target cartridges such as the 7mm RSAUM. Reloder 23 is like a slower version of Reloder 16 — a very temp-stable powder which has proven a worthy rival to H4350.

Ever heard of Alliant Reloder 23? Or Reloder 26? These two relatively new European-produced Reloder propellants were introduced in 2014. Most folks haven’t tried these Reloder powders because it took quite a while for the first shipments of RL 23 and RL 26 to arrive in the USA. But now these two new propellants are available in the USA, with substantial inventories in stock at some larger vendors. For example, Powder Valley has both RL 23 and RL 26 in stock now at $23.50 per pound. Many other vendors have ample RL 23, but RL 26 is a bit harder to find.

From our Forum members who shoot large magnum cartridge types with heavy bullets, we have heard good things about both RL 23 and RL 26. Reports from the field indicate that both these powders are delivering impressive velocities with low velocity ES/SD.

What are the characteristics of RL 23 and RL 26? That question was answered by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:

“Let me provide some factual info about these products. Some of the stuff that gets propagated is not correct. Reloder 23 is produced by our Swedish partner Bofors, and Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they are both made by Bofors, so that is incorrect.

I have also noticed people are equating Reloder 23 to Reloder 22, and Reloder 26 to Reloder 25. Both of those statements are definitely incorrect. We do state that the performance of Reloder 23 is similar to Reloder 22, and it is, in general burn speed terms, but they are most certainly not the same. We have worked quite a lot of recipes for Reloder 23, and they are not the same as Reloder 22. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”

Furrier says that RL 23 is NOT sensitive to temperature shifts: “Reloder 23 was developed to bring a truly temp-stable powder to the Reloder 22 burn-speed range using Bofors new process technology. This is the second product developed for us with this TZ® process, the first being AR-Comp™. We see terrific efficiencies, SDs, accuracy and flat temp response from these powders. Please try them, I think you will be impressed.”

Speed and More Speed with RL 26
Think of Reloder 26 as a high-velocity powder for big cartridges. Furrier explains: “Reloder 26 is produced with Nitrochemie’s latest generation EI® process technology. This is the same impregnation coating process used to produce Reloder 17, Reloder 33, and Reloder 50 for us, and it is fantastic. The “so what” on Reloder 26 is great ballistic efficiency, high bulk density so you can get more of the slow powder into the case to harness the energy, and decent, predictable extreme temp response. Reloder 26 is not as flat at temps as the TZ or Australian materials, but it is very manageable, usually in the 0.5 fps/°F range (depending on the application). Just as important, the pressure increases at hot are very manageable. We are using quite a bit of this powder in our Federal factory ammo due to the fantastic ballistics and accuracy.

Both of these new Reloder powders contain decoppering agent to help reduce coppering up your barrels, but this is nothing new for us. Bofors began adding decoppering agent to our Reloder rifle powders in the 2002 timeframe, and all our Swiss Reloders except 17 contain their proprietary additive. (We may include it in 17 at some point also, but right now we like it just the way it is.) Sorry we didn’t have a snappy name figured for the decoppering agents, we just did it.

Both of these new Reloder powders are also produced to the current highest level of ‘green’ technology. Actually, all of our Alliant rifle, pistol and shotshell reloading powders meet the current (tough) European requirements for elimination of nasty ingredients. They do not contain any dinitrotoluene or dibutylphthalate, which are a couple of the nasties that are commonly used in smokeless powders.
Thank you for your interest in our new powders.” — Paul Furrier, ATK

Day after day, one of AccurateShooter’s most-visited web pages is a reference guide featuring a comparative burn rate chart, ranking powders from fastest to slowest. Compiled by Hodgdon Powder Co., this Burn Rate Chart displays the relative burn rates of 163 different powders. Here is the latest table, released by Hodgdon in November of 2019.

You’ll want to download this Powder Burn Rate Table. This table shows the latest IMR powders including the Enduron series (IMR 4166, 4451, 4955, 7977), highlighted in green. This 163-entry comparison table provides vital information for hand-loaders. Note — this invaluable chart is not limited to Hodgdon and IMR propellants.
