If you don’t match your ammo to your chamber, bad things can happen, that’s for sure. A while back, Forum member BigBlack had an experience at the gun range that reminds us of the importance of safety when shooting. He encountered evidence that someone had fired the wrong cartridge in a 7mm WSM rifle. The problem is more common than you may think. This Editor has personally seen novices try to shoot 9mm ammo in 40sw pistols. BigBlack’s story is along those lines, though the results were much more dramatic. It’s too bad a knowledgeable shooter was not nearby to “intervene” before this fellow chambered the wrong ammo.
7mm-08 is Not the Same as a 7mm WSM
BigBlack writes: “I know this has probably been replayed a thousand times but I feel we can never be reminded enough about safety. This weekend at the range I found a ruptured case on the ground. My immediate thoughts were that it was a hot load, but the neck area was begging for me to take a closer look, so I did. I took home the exploded case and rummaged through my old cases until I found a close match. From my investigative work it appears someone shot a 7mm-08 in a 7mm WSM. Take a look. In the above photo I’ve put together a 7mm WSM case (top), the ruptured case (middle), and a 7mm-08 case (bottom).”
The photo reveals what probably happened to the 7mm-08 case. The shoulder moved forward to match the 7mm WSM profile. The sidewalls of the case expanded outward in the much larger 7mm WSM chamber until they lacked the strength to contain the charge, and then the case sides ruptured catastrophically. A blow-out of this kind can be very dangerous, as the expanding gasses may not be completely contained within the action.
Can’t Happen to You? Think Again.
This kind of mistake — chambering the wrong cartridge — can happen to any shooter who is distracted, who places even a single wrong round in an ammo box, or who has two types of ammo on the bench. One of our Forum members was testing two different rifles recently and he picked up the wrong cartridge from the bench. As a result, he fired a .30-06 round in a .300 Win Mag chamber, and the case blew out. Here is his story:
“I took two of my hunting rifles I have not used for over 25 years to the range yesterday to get new scopes on paper, a .30-06 and .300 Win Mag. I had four boxes of old Winchester factory ammo (two of each cartridge), which had near identical appearances. I accidentally chambered a .30-06 round in the Sako .300 Win Mag rifle. It sprayed powder on my face and cracked the stock at the pistol grip. If I had not been wearing safety glasses I might be blind right now.
You should always wear protective eyewear, EVERY time you shoot.
“I feel lucky and am very thankful for being OK — other than my face looks funny right now. I am also grateful for learning a valuable lesson. I will never put two different cartridges on the bench at the same time again.”
Guys — honestly, if you do anything today on this site, watch this video. You won’t be disappointed. Guaranteed. This is a very informative (and surprisingly entertaining) video. Every serious hand-loader should watch this video to see how cartridge cases are made. Your Editor has watched the video 5 times now and I still find it fascinating. The camera work and editing are excellent — there are many close-ups revealing key processes such as annealing and head-stamping.
VERY Informative Video Show Cartridge Brass and Ammunition Production:
Norma has released a fascinating video showing how bullet, brass, and ammunition are produced at the Norma Precision AB factory which first opened in 1902. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed (at multiple points along the case length) to check metal grain structure and hardness. Before packing, each case is visually inspected by a human being (3:27″ time-mark).
The video also shows how bullets are made from jackets and lead cores. Finally, you can watch the loading machines that fill cases with powder, seat the bullets, and then transport the loaded rounds to the packing system. In his enthusiasm, the reporter/narrator does sometimes confuse the term “bullets” and “rounds” (5:00″), but you can figure out what he means. We definitely recommend watching this video. It’s fascinating to see 110-year-old sorting devices on the assembly line right next to state-of-the art, digitally-controlled production machinery.

1. Powder Valley — Shooter’s World Powders, $25/lb and up
⏺ These SW powders can replace hard-to-find Varget, H4350, and more
With the popular ADI-produced Hodgdon powders — H4198, Varget, H4350, H4381sc — being in short supply, many shooters are turning to Shooters World (SW) powders. These are now available from Powder Valley and Midsouth at decent prices. For a Varget substitute, check out Shooters World Precision Rifle powder. Get 8 lbs. for $333.00 or 1 lb. for $44.00. For a slower powder there is SW 4350, with a burn rate similar to H4350 and Reloder 17. This is in stock now at Powder Valley at $344 for 8 lbs. or $45.50 for 1 pound. [NOTE: Bruno’s currently has Hodgdon H4350 1-pounders in stock at $48.50/lb — grab them while you can.] If you need a faster burn rate (similar to H4198), check out SW Tactical Rifle, a spherical powder (with H335 burn rate) that works great in .223 Rem. Available now at Powder Valley SW Tactical Rifle powder is very affordable — $195.99 for 8 lbs. and just $25.00 for one pound. Check with Midsouth for other Shooter’s World powder options in stock.

We think this would be an excellent secondary press used for decapping or bullet seating. This intro price — just $122.99 at Graf & Sons — is a great deal. NOTE: This press does NOT have priming capability — you must prime cases with a separate tool. Also, the power cord for the LED light is NOT included.

Sellier & Bellot is one of Europe’s older ammunition manufacturers, producing a wide variety of rifle and pistol ammo. The video below shows ammunition being made from start to finish, starting with raw materials. This is a fascinating video that is well worth watching. It shows some amazing machines in operation.
EDITOR: Guys, this really is an exceptional video that shows every aspect of production. I have watched dozens of videos about ammo making. This is definitely one of the BEST. Take the time to watch.
Based in Vlasim, Czech Republic, Sellier & Bellot was founded in August 5, 1825 by Louis Sellier, a German businessman of French lineage. His family were royalists who fled France during the French Revolution. Louis Sellier began manufacturing percussion caps for infantry firearms in a factory in Prague, Bohemia on the request of Francis I, the Emperor of Austria. Sellier was later joined by his countryman Jean Bellot.
Sellier & Bellot has also produced an interesting CGI video that shows what happens inside a rifle chamber and barrel when a cartridge fires can’t be seen by the naked eye (unless you are a Super-Hero with X-Ray vision). But now, with the help of 3D-style computer animation, you can see every stage in the process of a rifle round being fired.
In this X-Ray-style 3D animation illustrates the primer igniting, the propellant burning, and the bullet moving through the barrel. The video then shows how the bullet spins as it flies along its trajectory. Finally, this animation shows the bullet impacting ballistic gelatin. Watch the bullet mushroom and deform as it creates a “wound channel” in the gelatin.
Watch Video – Cartridge Ignition Sequence Starts at 1:45 Time-Mark
If you wonder how ammo is made, starting with raw metal, check out this video from Hornady. It shows how bullet jackets are formed from copper, followed by insertion of a lead core. The jacket is then closed up over the core with the bullet taking its final shape in a die (a cannelure is applied on some bullet types). Next the video shows how cartridge brass is formed, starting with small cups of brass. The last part of the video shows how cases are primed and filled with powder, and how bullets are seated into the cases, using an automated process on a giant assembly-line.

Hornady’s New 150,000-sq-ft Ammo Production Center
In 2018, Hornady opened a new, state-of-the-art factory. The 150,000-sq-ft Hornady West Facility, featured in the video below, handles ammunition production and product distribution — Hornady produces millions of rounds annually. Hornady cartridge brass and bullets will continue to be produced at Hornady’s 100,000+ square foot factory in Grand Island, Nebraska. The Grand Island factory is open for tours Monday through Thursday. Hornady Manufacturing was founded by Joyce Hornady in 1949, so 2019 marked the company’s 70th anniversary.
