Mega-Sized 14.5x114mm Round — Russia’s Colossal Cartridge

14.5x114 mm cartridge Russia South Africa
Photo courtesy Elardus de Lang, Truvelo Manufacturers Armoury, South Africa.

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.

.50-Caliber Christmas — Big Boomer Blasts Xmas Ornaments

Barrett 50 Caliber .50 Ca Xmas Christmas shooting video

This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame. For best viewing, you may want to change your video settings to 720p or 1080p High Definition and view full-screen (using the video controls).

50 Caliber Barrett slow motion Christmas

The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.

Sunday Gunday: World-Record-Setting .375 CheyTac TubbGun

David Tubb Adaptive Target Trifle ELR World Record Chase Stroud

Shown above is David Tubb, the legendary 11-time National High Power Champion, posing with a very serious rifle used in the Extreme Long Range (ELR) game. David has jumped into the Extreme Long Range discipline in a very big way, producing a .375-caliber, long-barreled ELR version of his famous Tubb rifle, called the Adaptive Target Rifle (ATR). A version of this rifle, piloted by David’s son-in-law Nate Stallter, set an ELR World Record in January 2018. See video below for a full report.

This video shows Team TUBB setting a new ELR World Record of 2011 Yards using the Tubb Adaptive Target Rifle in .375 CheyTac. Nate Stallter nailed three shots at over one mile — 1768 yards. Then Nate broke his own record, going 3 for 3 at 2011 yards. ELR Central hosted this match, held at the Front Sight gun range, Pahrump, Nevada on January 21, 2018.

David Tubb Adaptive Target Trifle ELR World Record Chase Stroud

For the Extreme Long Range (ELR) discipline, David Tubb developed a .375-caliber, long-barreled ELR version of his famous Tubb rifle, called the Adaptive Target Rifle (ATR). A version of this rifle, piloted by David’s son-in-law Nate Stallter, set an ELR World Record in January 2018.

David Tubb Talks about KO2M and Extreme Long Range Shooting

David Tubb’s long-range rifles have performed well in Extreme Long Range shooting. AT the 2019 NRA Extreme Long Range Championship, David Tubb won the Heavy Gun Division. In this video, created during the King of 2 Miles (K02M) competition at the Whittington Center in New Mexico, David talks about the challenges of ELR shooting, and cartridge selection. Big, heavy, large-caliber bullets with ultra-high BCs are favored for the ELR game, but recoil and cost must also be considered.

About the .375 CheyTac Cartridge

Peterson .375 Cartridge Brass Cheytac K02M

Some of the most successful ELR cartridges are based on the CheyTac family, including the .375 CheyTac (9.5×77) and .408 CheyTac (10.36 x 77). This .375 Cheytac cartridge has proven to be tough and accurate. And it is capable of winning — our friend Derek Rodgers won the 2017 King of 2 Miles (K02M) event shooting a .375 CheyTac (9.5×77).

.375 CheyTac — K02M-Winning, World-Beating Cartridge

Derek Rodgers was the 2017 King of 2 Miles. Derek is also the first-ever human to ever hit the maximum distance target target at 3368 yards (1.91 miles). His cartridge choice? The .375 CheyTac. Derek ran Cutting Edge Bullets in Peterson brass with Hodgdon H50BMG powder.

Q: Why did you choose the .375 CheyTac cartridge?

Derek: When I was asked to join the Applied Ballistics Team, I needed to get an ELR rifle built in a short period of time. I was under a very tight time schedule to get the project complete. In an effort to eliminate variables, I decided to keep things standard and as simple as possible. I chose the .375 CheyTac for the ease of getting components. The larger rifles are more difficult to get components quickly and I felt like the .375 CheyTac had enough attributes to be competitive at ELR distances.

Look Inside Ammo — Cutaway Cartridge Views

sliced cutaway ammo ammunition FOG diagram

Here’s something you don’t see every day — the inside of loaded cartridges, sliced halfway through. This lets you see how bullet core, jacket, cartridge case, powder, and primer all fit together. Give credit to the folks at FOG Ammunition for creating this interesting series of cut-through ammo images. We show four cartridges here: the .308 Winchester, 9mm Luger, 300 BLK, and .50 BMG. You’ll find two more (the .223 Remington and .45 ACP) at www.FogAmmo.com.

sliced cutaway ammo ammunition FOG diagram

This .308 Winchester model took on a different approach by only cutting the brass case and displaying the full bullet, primer and powder load. A spec amount of powder was used to create the model powder form. An estimated 10% volume was added during the forming process, along with an undetermined amount of air pockets.

sliced cutaway ammo ammunition FOG diagram

This bisection is a 9mm Luger Jacketed Hollow Point round with flake powder held together with super glue. After this self-defense round was cut by a trained professional the round was polished by hand. This might look like stick powder, but those are in fact flakes stacked up in cross-section. Designed in 1901 by Georg Luger, this popular cartridge is used by civilians, military, and law enforcement.

sliced cutaway ammo ammunition FOG diagram

For this model of the .300 AAC Blackout (aka 300 BLK), a Dremel tool was used to create a pie cut within the bullet and brass case. A measured amount of power, roughly 65% of spec charge, was placed inside the case with super glue. This cartridge was originally optimized for subsonic use with a suppressor, so the amount of powder used is small relative to the nominal case capacity. That leaves more room for the relatively large .30-caliber bullet.

sliced cutaway ammo ammunition FOG diagram

Last but definitely not least is the .50 Caliber BMG round (aka .50 Browning Machine Gun). Famed for its wartime use in the M2 Machine gun, the .50 BMG round is also used in civilian Long Range competitions. A typical .50 BMG cartridge holds over 225 grains of powder. That’s almost ten times the amount in a 5.56×45 NATO Round! To demonstrate the size of the .50 BMG, check out that .223 Rem for comparison.

Big Presses for Jumbo-Sized Cartridges Used in the ELR Game

Ko2m king two miles ELR .416 Barrett cheytac .50 BMG Extreme long range press

In the ELR game, particularly the King of 2 Miles (KO2M), it’s “go big or go home”. The top shooters run large-capacity cartridges that push large-caliber, ultra-high BC bullets at very high velocities. Bullets launched by cartridges such as the .416 Barrett can sustain supersonic velocities at Extreme Long Ranges — and that’s what it takes to win. The .416 Barrett can launch a 550-grain solid bullet at 3000+ FPS.

2018 and 2019 Kings of 2 Miles Loaded on RCBS Presses
So how do you load jumbo cartridges such as the .416 Barrett? It takes a big, heavy, super-strong reloading press. We’ve learned that two recent King of 2 Miles champions, Paul Phillips (2019) and Robert Brantley (2018) both loaded their KO2M ammo on RCBS AmmoMaster .50 BMG presses. Phillips loaded .416 Barrett ammo, while Brantley loaded a similar .416 MCS cartridge.

In 2018, Robert Brantley topped the field using his custom .416 MCS cartridge. Then in 2019, Paul Phillips won the K02M competition shooting a .416 Barrett, with Brantley a close second. Both Phillips and Brantley use the RCBS AmmoMaster .50 BMG single stage press kit and RCBS .416 Barrett dies to hand-load for extreme long-range. “My ammo has been much more consistent after switching to the RCBS press and dies,” remarked Phillips, who runs the Global Precision Group. Brantley said he uses RCBS products for most of his reloading needs — from the dies and AmmoMaster, to the ChargeMaster and Brass Boss. His custom .416 MCS loads launch a 550-grain bullet more than 3,100 fps.

Big Boomer .50 BMG Boasts Impressive Half-MOA Accuracy

.50 BMG Richard King Texas half-MOA

A few seasons ago, Texas gunsmith Richard King built an impressive .50 BMG target rifle for a customer. Equipped with a beefy McMillan stock, this rig has delivered some very impressive accuracy. Check out that target shot during break-in. Using On Target software, we measured this 3-shot group at 0.476″ or 0.454 MOA. Not bad for a beast with VERY serious recoil. Do you think you could beat that 0.476″ with your AR15 shooting puny .223-caliber bullets?

.50 BMG Richard King Texas half-MOA
Compare the dimensions of that massive 50-Cal action to a Rem 700 action in the middle. When you’re shooting a Fifty, size matters!

On Facebook, some folks were surprised a guy could wring that kind of accuracy out of a monster .50 BMG. One wag posted: “Yikes! He will need flinch therapy after shooting that beast.”

Another Facebooker joked: “When shooting a .50 BMG you say…In your best Crocodile Dundee voice…that’s not a gun, THIS is a gun!”

Richard King responded that this customer has quite a bit of experience with jumbo-caliber rifles: “Remember this is the guy that shot a .338 Lapua in a two-day F-Class match. Recoil might actually be easier on this 50, given the fact that it has more weight and a brake.”

.50 BMG Richard King Texas half-MOA

Richard King showed us the monster 13-lb BAT action for this rifle at the 2018 Berger SWN. Honestly, the big BAT .50 BMG action was HUGE — with the bolt fully extended it was the size of your forearm (to the finger tips). Richard joked “This weighs almost as much as an F-TR rifle (before optic) all by itself”.

Specialty Tools for the Big .50 BMG
Yes, the .50 BMG is one huge cartridge. Thankfully, there are some special tools for loading the jumbo-size round. Giraud Tool produces a specialty comparator for the 50-Cal cartridge. The double-ended .50 BMG comparator is quite versatile. In one orientation you can measure base-to-ogive bullet length and also measure cartridge OAL from rim to bullet ogive. When reversed, you can use the comparator to measure cartridge headspace. Priced at $33.00, Giraud 50 BMG Comparator gauge is constructed of 303 stainless and fits most any vernier, dial, or digital caliper. CLICK HERE for more info.

Sunday GunDay: Falling-Block .50 BMG — Beauty of a Beast

.50 BMG J.T. 50-caliber Smith breech block falling block custom rifle
.50 BMG J.T. 50-caliber Smith breech block falling block custom rifle

This is one amazing .50-caliber rifle. Along with the lever-actuated falling block, it has a massive swing-out breech block like you’d find on a field artillery piece. The action is so wide that the sights and scope are offset. You’ve heard of the “Beauty and the Beast”? Well here the Beast IS a Beauty….

View looking down at the action from above. Note the hinged Breech-Block.
.50 BMG J.T. 50-caliber Smith breech block falling block custom rifle

This extraordinary example of gunsmithing art was crafted by the late J.T. (Jack) Smith of Sudbury, Massachusetts. This unique .50-caliber rifle features an aircraft machine gun barrel cut down to 38-1/4″, and turned octagon to round (in the style of Schuetzen rifles). The round portion of the barrel is tapered with a heavy boss at the muzzle. The barrel is inlaid in gold on both left and right side top flats. Custom scope bases are fitted to the receiver and to the top of the barrel. These hold an externally adjusting Unertl 15X target scope in offset scope mounts.

.50 BMG J.T. 50-caliber Smith breech block falling block custom rifle

Huge Falling Block Receiver
The massive receiver (8″ long x 2-3/4″ wide x 3″ deep) is remarkable in design and construction. Machined from solid steel, the action incorporates several unique features. Note the hinged Howitzer-style breech block which swings to the right and mortises into the back of the receiver in the loading slot, providing a back-up for the falling block. We’ve never seen anything like that on any rifle. The one-piece floorplate/lever incorporates a Ruger No. 1-style latch which locks into the bottom of the trigger guard. The entire floorplate and lever retract downward. Firing is accomplished by means of a striker mounted in the hinged (swing-out) breech block. This is manually cocked with another lever on top of the breech block. Dropping the falling block activates the extractor which removes the spent case.

Offset Sights
This rifle features a custom-built, windage-adjustable offset front sight plus a custom-built vernier tang sight with aperture offset to the left side. The sights are offset to the left for a right-handed shooter, to correct for the extreme width of the receiver, allowing a more comfortable head position.

.17 Incinerator Based on .50 BMG Delivers Mach 5 Velocity!

.17 Caliber Incinerator Wildcat Varmint cartridge

In the world of varmint cartridges, it’s all about speed. Higher velocity delivers flatter trajectories, and more dramatic impacts on critters. To achieve higher speeds, handloaders have experimented with many extreme wildcats — big cases necked down to a smaller calibers. Here we present what may be the most extreme wildcat cartridge of all, the .17 Incinerator — a .50 BMG necked down to .17 caliber. Created by Ammo-One, a custom cartridge company, the .17 Incinerator offers blistering performance. The special lathe-turned 33gr projectiles* exit the barrel at 5883 Feet Per Second — that’s over Mach 5, five times the speed of sound!

Mach 5 is 3836.35 mph at sea level, which equates to 5626.64 Feet Per Second (FPS). The remarkable .17 Incinerator achieves this stunning velocity by burning over 230 grains of powder in a highly modified .50 BMG case. The velocity of this cartridge (still well over Mach 5 at 100 yards) delivers an incredible amount of energy on target. A hit literally vaporizes a varmint, as you can see from the image below.

.17 Caliber Incinerator Wildcat Varmint cartridge
For more dramatic varmint images, visit www.FogAmmo.com.

It takes a special barrel to shoot the .17 Incinerator. Kent Wilson of Ammo-One, who helped develop this extreme wildcat, explains: “The speeds are so great we had to use a custom 3-groove, polygonal-rifling 1:20″-twist barrel to keep the bullets from disintegrating on launch. The polygonal land/groove geometry reduces bullet engraving, which also helps keep the bullets in one piece. Also we must use solids — regular jacketed bullets can’t handle these speeds”.

Even More Speed — the .17 Incinerator Improved
While the .17 Incinerator is commercially available, there is an even more extreme “Improved” version of this case, with a radical 50-degree shoulder that yields even greater case capacity. The .17 Incinerator Improved (17 IN-IMP), shown below, can hold 20 grains more powder, promising velocities approaching Mach 5.5 or 6189.3 FPS. Now that’s really cookin’!

Incinerator .17 Caliber varmint wildcat cartridge

*Because of the ultra-high velocity generated by the .17 Incinerator, solid bullets must be used. Conventional jacketed projectiles would disintegrate before they reached the target.

Halloween Boom Time — Pumpkin Blastin’ with Explosives

Halloween Wallpaper explosion pumpkin
Image from WallpapersBuzz.

Today is October 31st, Halloween (originally “All Hallows Eve”). That means it’s pumpkin time. Just how much fun can you have with pumpkins? Watch these two videos and find out. In the first video, the RatedRR team sends a few orange gourds to pumpkin heaven using Det Cord, C4, and binary explosives. The sequence starting at the 2:00 minute mark in the first video is truly amazing. WARNING: DO NOT TRY THIS AT HOME!

Watch Pumpkin Blasting with Explosives

In the next video, a pumpkin carved as a Death Star serves as the target for a .50 caliber rifle (looks like a Barrett M82 .50 BMG). As you may guess, the pumpkin Death Star suffers the same fate as the Hollywood version in Star Wars. NOTE: At the 0:42 mark in the video, a graphic displays “30,000 FPS”. That’s the high-speed camera’s frame-per-second rate, NOT the projectile velocity in feet-per-second.

Watch .50 BMG Rifle vs. Death Star Pumpkin

Warning: These demonstrations were carried out on closed ranges by experienced professionals certified to use explosives. Possession of C4 and Det Cord may be a violation of various Federal, State, and local laws. Detonating cord and C4 are classified as high explosives and are regulated by the BATFE. Don’t even think about trying to repeat these stunts on your own.

Jerry Miculek Carves a Pumpkin with a Barrett .50 BMG

In October 2015, the legendary Jerry Miculek won the Trijicon Shooting Challenge at the Rockcastle Shooting Center. That impressive victory earned Jerry big bucks — a $50,000 grand prize. By any measure, that’s some serious cash — mucho dinero.

To celebrate his October Trijicon Challenge victory, Jerry Miculek decided to do some pumpkin carving — with a .50 BMG Barrett rifle.

Shooting the 30-lb rifle off-hand, Jerry blasted some serious holes in Mr. Pumpkin. Needless to say, the results were dramatic, if somewhat messy. Advancing the science of terminal ballistics, Jerry (not surprisingly) confirmed that “the 663-grain bullet did manage to penetrate the pumpkin all the way.”

Go Big or Go Home — Care and Feeding of .50 BMG Rifles

fifty caliber shooting association

Owning and Feeding ‘The Big Bore’ — .50 BMG

Is The Challenge Of Big Bore Extreme Range Shooting Right For You?
By James Patterson
This article originally written for the Sinclair Reloading Press

Fifty 50 Caliber shooting Association

Handling a .50 BMG Rig
Is a .50 BMG caliber rifle difficult to shoot? Not at all. The relatively heavy weight of a standard rifle at 30 pounds or more combined with a very efficient muzzle brake makes it a pleasure to shoot. The typical recoil can be compared to a .243 rifle or a 12 gauge trap load. On the other hand, the burning of a typical load of 230 grains of powder combined with that muzzle brake makes the muzzle blast experience exhilarating. A first time shooter will fire, pause for a moment in awe at the muzzle blast, and then break out into what has become known as “The 50 Caliber Grin”, almost impossible to wipe from ones face. My daughter started competing with the .50 BMG at 18 (115 lbs of tall skinny girl) and happily shoots 100+ rounds in the course of a match, her grin on the last round is as wide as on the first! Many members and competitors in the FCSA are women and many have distinguished themselves as excellent marksman having set world records on numerous occasions.

50 BMG Fifty Caliber Shooting Association

Cost of Big-Bore Shooting
Is owning and shooting a .50 BMG caliber rifle expensive? Relatively speaking yes, but one must put it into perspective. Rifles may run from $2500 to $7000, maybe even more for a top of the line custom rifle. A good scope will set you back $1000 to $3500. And while excellent commercial ammo is made, it is hard to find these days and runs from $4 to $6 a round. Most serious shooters start reloading for the rifle as soon as practical, not only for the economics of reloading but also for the ability to fine tune custom ammo for their specific rifle. It’s a very rare match that is won shooting commercial ammo. I recently compared the cost of my hobby — owning, shooting, and competing with the 50 BMG — with a friend whose hobby is snowmobiling. Factoring in the cost of equipment, licensing, gasoline, clothing, etc. it was soon obvious that my hobby was significantly less expensive than his.

Getting Started
FCSA 50 BMG Fifty Caliber Shooting AssociationSo how does one get started? You could do as I did, purchase a rifle not knowing what you were really getting into; or you could come out to a FCSA-sponsored event, shoot a number of different rifles, rub shoulders with those who have already taken the plunge, and see if this sport is right for you. While membership in the Fifty Caliber Shooters Association (FSCA) is required to compete at a FSCA event, membership is not required to come and experience first hand what is going on. If you have any inclination that you are interested in the extreme sport of long rang, big bore shooting then a year’s membership in the FCSA is only $60 ($20 for active duty military) a significant bargain if it helps you make just one well-informed equipment choice. In addition one of the primary functions of the FCSA is helping to identify active members near you who can help you understand just what is involved and help you ‘get your feet wet’ in this challenging sport.

Fun Fifty — Armalite .50 BMG for Long-Range Steel

Wide Open Magazine video .50 Caliber 50 BMG Fifty G.A. Precision GA 50-Cal
This Armalite AR-50A1 .50 BMG rifle was modified by G.A. Precision.

If you’re a fan of big boomers, and love shooting steel, then definitely watch this Wide Open Magazine video. This covers a .50 BMG build by our friends at G.A. Precision (GAP). The rifle started as an Armalite AR-50A1 ($3359.00 MSRP). Then GAP fluted the barrel and swapped the factory muzzle brake with a more compact brake from American Precision Arms*. Then, as modified, the entire rig was given a rugged Cerakote finish.

The video has nice background music, great aerial drone footage, and of course some serious firepower. Using Hornady .50 BMG ammo, GA Precision’s George Gardner and his Wide Open friends shoot the big Fifty from the bench as well as prone. Enjoy!

About the .50 BMG Cartridge

The .50 Browning Machine Gun (.50 BMG, aka 12.7×99mm NATO or 50 Browning) is a cartridge developed for the Browning .50 caliber machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard cartridge for NATO forces as well as many non-NATO countries.

John Browning had the idea for this round during World War I in response to a need for an anti-aircraft weapon, based on a scaled-up .30-06 Springfield design, used in a machine gun based on a scaled-up M1919/M1917 design that Browning had initially developed around 1900. According to the American Rifleman: “The Browning .50 originated in the Great War. American interest in an armor-piercing cartridge was influenced by the marginal French 11 mm design, prompting U.S. Army Ordnance officers to consult Browning. They wanted a heavy projectile at 2700 FPS, but the ammunition did not exist. Browning pondered the situation and, according to his son John, replied, ‘Well, the cartridge sounds pretty good to start. You make up some cartridges and we’ll do some shooting’.”

* In the video, George mistakenly says “American Patriot Arms”, but the brake is made by Georgia-based American Precision Arms.

Halloween Pumpkin Blasting — Don’t Try This at Home

Halloween Wallpaper explosion pumpkin

Today is October 31st, Halloween (originally “All Hallows Eve”). That means it’s pumpkin time. Just how much fun can you have with pumpkins? Watch these two videos and find out. In the first video, the RatedRR team sends a few orange gourds to pumpkin heaven using Det Cord, C4, and binary explosives. The sequence starting at the 2:00 minute mark in the first video is truly amazing. WARNING: DO NOT TRY THIS AT HOME!

Watch Pumpkin Blasting with Explosives

In the next video, a pumpkin carved as a Death Star serves as the target for a .50 caliber rifle (looks like a Barrett M82 .50 BMG). As you may guess, the pumpkin Death Star suffers the same fate as the Hollywood version in Star Wars. NOTE: At the 0:42 mark in the video, a graphic displays “30,000 FPS”. That’s the high-speed camera’s frame-per-second rate, NOT the projectile velocity in feet-per-second.

Warning: These demonstrations were carried out on closed ranges by experienced professionals certified to use explosives. Possession of C4 and Det Cord may be a violation of various Federal, State, and local laws. Detonating cord and C4 are classified as high explosives and are regulated by the BATFE. Don’t even think about trying to repeat these stunts on your own.
