Can you form a wildcat cartridge such as the 6 Dasher without expending primer, powders, and bullets? Absolutely. Using the hydro-forming method you can form improved cases in your workshop with no firing whatsoever, so there is no wear on your precious barrel. Watch this video to see how it’s done:
6 Dasher Case Hydro-Forming Demonstration:
Forum member Wes J. (aka P1ZombieKiller) has produced a helpful video showing how to form Dasher cases use the Hornady Hydraulic forming die kit. This includes a two-part die (body and piston), and a special shell holder. To form the case, you insert a primer in your virgin brass, top the case off with with a fluid (water or alcohol), then run the case up into the Hydro-forming die. A few stout whacks with a hammer and your case is 95% formed.
This same procedure can be accomplished with a Whidden Gunworks 6mm Dasher hydraulic form die. We like the Whidden hydro-forming die for its production quality and consistent results. This Whidden system works great according to our Forum members.
Hydro-Forming Procedure Step-by-Step:
1. Insert spent primer in new 6mmBR brass case.
2. Fill with water or alcohol (Wes prefers alcohol).
3. Wipe excess fluid off case.
4. Place case in special Hornady shell-holder (no primer hole).
5. Run case up into Hydraulic forming die.
6. Smack top piston of forming die 3-4 times with rubber mallet or dead-blow hammer.
7. Inspect case, re-fill and repeat if necessary.
8. Drain alcohol (or water) into container.
9. Remove primer (and save for re-use).
10. Blow-dry formed case. Inspect and measure formed case.
Wes achieves very uniform cartridge OALs with this method. He measured ten (10) hydro-formed 6 Dasher cases and got these results: two @ 1.536″; 2 @ 1.537″; and 6 @ 1.538″.
Three or Four Whacks Produces a 95%-Formed Case
With a Whidden or Hornady hydro-forming die, hydraulic pressure does the job of blowing out the shoulders of your improved case. The process is relatively simple. Place a spent primer in the bottom of a new piece of brass. Fill the case with water, and then slip it into a special Hornady shell-holder with no hole in the middle. Then you run the case up into the forming die. Now comes the fun part. You gently insert a plunger (hydraulic ram) from the top, and give it three or four stiff whacks with a mallet (or better yet, a dead-blow hammer). Remove the plunger and you have a 95% formed case, ready to load.
Special Shell-Holder
Hornady supplies a shell holder made specifically for the hydro die; there’s no hole in the bottom of it. Just insert a spent primer into the primer pocket and you’re ready to go. The spent primer, combined with the solid shell holder, keeps the water from seeping out of the primer pocket. The primer pushes out a little bit during this process, but it’s impossible for it to come out because of the way the shell holder is designed. The shell holder has a grove which allows the case to slide out of the shell holder even when the primer protrudes a bit.

Ever wanted to see how Nosler bullets and cartridges are made? Here’s your opportunity. The Rocky Mountain Elk Foundation (RMEF) has produced a video (“Quality First”) that offers a behind-the-scenes look inside Nosler’s Oregon factory that produces bullets, brass, and ammunition.
Video Showcases Nosler Production Facility and Ballistics Lab
RMEF representatives were provided with unprecedented access into Nosler’s famously-guarded manufacturing plant to show the technology used by Nosler to produce bullets and ammunition. The “Quality First” video showcases Nosler’s complex production processes that include technologically advanced machinery, and stringent quality control measures.
After the intro, this video illustrates Nosler’s bullet construction techniques with a cool animation sequence. The video then showcases the Nosler ballistics lab, inspection room, and packaging line.
The “Quality First” video starts with the history of the company, tracking Nosler’s development from the 1940s. Then the video shows the bullet construction techniques followed by a ‘walk-though’ in the factory, showing the sophisticated machinery used to make bullets, brass, and ammunition. “‘Quality First’ isn’t just a saying that’s printed on our factory walls, it’s the guiding principle that affects every decision we make” says Mason Payer, Senior Marketing Manager at Nosler.
Nosler has completely upgraded its Nosler.com website that provides Nosler product information, online shopping, and customer service. The redesigned Nosler.com site now boasts improved e-Commerce functionality. This should allow faster order processing and shipping, and allow customers to get real-time order status, plus up-to-date tracking information.
Better Search and More Detailed Product INFO
On the updated Nosler website, navigation is easier, and the search function is improved, allowing customers to search Nosler products by name, product line, cartridge, caliber, activity, and several other parameters. The updated product listings have more detailed specifications. For example the site now includes velocity, energy AND drop charts for all Nosler ammunition products.

The Biden State Department has banned imports of Russian-made firearms and ammunition. Russian firearms and ammo importation will be blocked for a minimum of 12 months starting September 7, 2021. The State Department Notice states:
New sanctions imposed today under the CBW Act include:
Restrictions on the permanent imports of certain Russian firearms. New and pending permit applications for the permanent importation of firearms and ammunition manufactured or located in Russia will be subject to a policy of denial.
Action Will Harm U.S. Firearms Owners
The Gun Owners of America (GOA) criticized the action, stating it will NOT achieve its stated purpose, but will only harm American hunters, shooters, and gun owners:
“It is clear to us that the intention is not to harm Russia but rather to hinder the acquisition of firearms and ammunition by American citizens.
Once again, the Biden Administration’s actions are misplaced. Ending imports by licensed importers will not stop drug dealers, murderers, and other assorted street criminals. It will, however, harm legitimate U.S. businesses while driving up the cost of other ammunition due to more buyers chasing a smaller supply.
We recognize the devastating implications these sanctions would have on individual gun owners amidst a national ammunition shortage. We are currently exploring administrative, congressional, and legal avenues to respond to these new sanctions.”
Ammo Shortages Will Worsen Dean Weingarten cautions that the new ban will lead to more ammo shortages:
“This is the second round of sanctions imposed on Russia by the United States over the Aleksey Navalny incident. The first round of sanctions did not ban the importation of Russian ammunition or firearms.
It is unclear how long supplies in the pipeline will last. The announcement is likely to rekindle the ammunition bubble for calibers commonly imported from Russia, such as 7.62×54, 7.62×39, 5.45×39, 5.56×45, and even match grade .22 ammunition.”
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).
So how does powder grain 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.
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.
With shortages of factory ammunition, many more gun owners are reloading their own ammo these days. Redding offers handy, printable files for load data records and box labels.
Redding Reloading offers a handy Handloader’s Data Sheet in printable PDF format. This FREE form allows hand-loaders to document their tool settings, bushing size, powder charge, load specs (COAL etc.), and case prep status. In addition, the form allows you to enter your load testing information, complete with chronograph data, group size, zero range, and wind/temp conditions. With this single, handy form you can document all the vital information for your particular cartridges and loads. We suggest you print these out, 3-hole-punch them, and then keep them in a three-ring binder.
We’ve seen various reloading log templates, but this Redding form (shown below) is better than most because it combines both reloading data AND range-test data in one place. You can see all key details of the reloading process (tool settings etc.) plus the end results — how the load actually performed over the chronograph and on paper. This form allows the user to capture a large amount of information for later use, while accurately track load development. Go to Download Page.
FREE Ammunition Box Label Template Redding Reloading has also developed a printable template for your ammo boxes (see photo at top of article). This lets you put all vital load info on your ammo boxes. There are fields for: Date, Cartridge, Powder, Grains, Bullet, Weight, Primer, Case type. Designed for Avery 5260 (or similar) label sheets, this label template allows you to print 30 labels at one time. You can purchase the Avery 5260 peel-off printable label sheets at office supply stores.

Believe it or not, here is a cartridge that makes a .338 Lapua Magnum look like a toy. The 14.5x114mm cartridge was designed as a MG and rifle-fired anti-materiel round. To translate from the metric system to caliber and inches, the round is a mammoth .57 caliber which measures 4.49 inches to the case mouth, and 6.13 inches overall. That jumbo-sized case holds a whopping 655 grains of powder. Commonly-loaded projectiles weigh 920-1030 grains. The 993gr armor-piercing projectile has a muzzle velocity of approximately 1006 meters per second (3300 fps) and can penetrate 30-32 millimeters of RHA steel at a range of 500 meters.
The top photo comes from Elardus De Lang, a Forum member who works at the Truvelo Manufacturers Armoury in South Africa. Elardus also provided an impressive video showing the massive 14.5x114mm being shot from prone with a Truvelo-built bolt-action rifle. Elardus tells us: “Here is a video, with a slow-motion ending, of our 14.5x114mm anti-materiel rifle being fired in our indoor testing facility. This caliber is a true beast! It propels a 993gr Armor-Piercing Incendiary bullet to 3300 fps, burning 480 grains of powder in the process. [This shows] that rifles of that power level can actually be shootable. The concussion indoors is something to experience……every shot feels like you are being punched in the face, and the heat from the muzzle flash actually hits you like a wave!”
14.5x114mm Cartridge Design and Dimensions
The 14.5×114mm has 42.53 ml (655 grains H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions. Cartridges typically use lacquered steel cases, but some countries also use brass cases for the 14.5x115mm.
All dimensions are in millimeters (mm). Americans would define the shoulder angle at alpha/2, or 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1:17.91″) with eight lands/grooves. According to official guidelines, the 14.5×114mm can handle up to 360 MPa (52,213 psi) piezo pressure.
14.5x114mm Cartridge History
The 14.5×114mm (.57 Cal) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, but was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armoured personnel carriers from the BTR-60 to the BTR-80 and for heavy anti-material sniper rifles. The cartridge was designed in 1939 and first issued in 1941.
