Saturday Movies: Ammo Production Factories in USA and Europe

Lapua norma sellier bellot ammunition ammo factory germany finland sweden usa

While many AccurateShooter.com readers load their own competition centerfire rifle ammunition, we all still need factory ammo for our rimfire rifles in .17 and .22 calibers. And most of the 65+ million American handgun owners rely on factory-made ammunition for their pistols and revolvers.

Today’s video collection showcases state-of-the-art ammunition factories in Europe and the United States. You can see the extremely accurate Lapua .22 LR ammo being produced, as well as excellent centerfire ammunition being made by Norma, Remington, Sellier & Bellot and other makers.

From the creation of lead bullet cores to the final packing of ammunition, you can see it all in these videos. Watch primers being made, brass being annealed, bullets being jacketed, tips being inserted, and every phase of production. Weighing and testing procedures are also revealed.

Modern Ammo Production in Multiple Facilities

This 11.5-minute video shows highly automated bullet and ammunition production in multiple facilities in Europe and the USA. You can see bullets produced from start to finish beginning with lead smelting. Then watch pistol and rifle cartridges being made on modern, computer-controlled assembly lines. Watch from start to finish. Here are some notable highlights:

00:10 — Lead Melting Pots and Billet Caster
01:20 — Lead made into strings and then formed into bullets
01:50 — Brass alloy sheets fed into machine and then punched (2:10-2:35).
03:35 — Lead pistol cores being produced
04:15 — Pistol ammo being packaged
06:15 — Ammo loaded into belts
07:15 — Completed primers being shuttled then loaded into brass (Second factory)

08:45 — Cartridge case draw
09:06 — Priming pistol cases
09:20 — Bullet production and weight control (10:02)
10:08 — Cartridge assembly and cartridge sealing (10:38)
11:00 — Pistol ammo packaging

Lapua Rimfire Ammunition Production in Germany

This video shows Lapua rimfire ammo production in Schönebeck, Germany. The video shows quantities of the excellent X-ACT .22 LR ammunition being produced and packaged. Starting at the one-minute mark, you can see the ammo being inspected with advanced scanning machines. Then at 1:16 time-mark you can see the ammo accuracy-tested in a tunnel, with results displayed on a computer screen (1:27).

Norma Ammunition Production in Sweden

In this video, the RecoilTV team lead by EIC Iain Harrison ventures to Sweden to visit the Norma ammunition production plant in Huvudentré, Sweden. Demand for Norma ammo has risen dramatically. A Norma marketing manager notes that production has doubled in the last three years.

This second Norma ammunition video shows close-ups of the production process and the machinery used for centerfire ammo. This was filmed at the Norma factory in Åmotfors, Sweden, which has operated continuously for over 120 years. Among the many interesting highlight is a sequence showing how polymer bullet tips are inserted. See 6:50 time-mark.

Sellier & Bellot Ammunition Factory in Czech Republic

In this video, Larry Vickers of Vickers Tactical tours a Sellier & Bellot ammunition plant in the Czech Republic. This video shows details of primer production as well as bullet-making, brass-making, and production-line cartridge manufacturing.

Remington Ammunition Plant Re-Opened by Vista Outdoors

This video shows ammo production at the re-opened Remington ammunition plant in Lonoke, Arkansas. “This is one of the largest ammunition manufacturing plants in the world” said Mark Keefe, NRA Publications editorial director. “It was set up in 1969 by DuPont, who owned Remington at the time. They do it all here. Cases, bullets, centerfire rifle, centerfire pistol, rimfire and shotshell.” It’s great to see this plant back in production after Remington Ammunition filed for bankruptcy in 2020 and the assets of the Remington conglomerate were auctioned off. Ultimately, Vista Outdoor, owner of Federal, CCI and Speer, purchased the assets of Remington Ammunition and got the Lonoke plant running again, better than ever.

How Travel Humidity Changes Can Affect Ammo Performance

This article comes from the Bryan Litz Ballistics Facebook page. That page offers valuable tips on ballistics, marksmanship, and precision reloading, with updates nearly every day of the year. One recent post relates to velocity changes that can occur when traveling away from home.

Q: Is there a physical reason, other than temperature, why sometimes we see a difference in muzzle velocity when we travel to a different location?

Bryan Litz notes: “One reason we found for this is powder humidity. We put out a video on our YouTube channel called “Powder Humidity / Temperature and Storage”. Watch the video below to learn more specifics about the effects of humidity and temperature changes on your loaded ammunition.

Basically, if you develop a load at home, then travel to a dramatically different environment (drier or wetter), and your ammo isn’t hermetically sealed, it can affect the powder burn rate. This can cause muzzle velocity to change.

Humidity Field Tests with 6.5 Creedmoor and H4350

To learn more about the effects of humidity on velocity and ammo performance, we recommend another article found on the ChronoPlotter.com website. This article begins by reviewing research done by Applied Ballistics, Norma, and Vihtavuori.

Then author Michael Coppola covers his extensive experiments with Hodgdon H4350 powder stored with different relative humidity (RH) levels then loaded in 6.5 Creedmoor rounds. The results were quite dramatic: “At its lowest humidity (14.5% RH), our 41.50 gr H4350 charge clocked in at an average 2,879 fps, peaking at 2,901 fps. Its highest humidity (83.5% RH) saw an average of 2,650 fps with a lowest velocity of 2,635 fps. The entire experiment saw an Extreme Spread of 266 fps. Between the desiccated and 66.5% samples, a 10% change in RH resulted in a velocity change of about 25.6 fps. Above 66.5%, this effect nearly doubled and a 10% change in RH resulted in a change of about 57 fps.

Effective ‘Big Batch’ Methods for Lubing Cases Before Sizing

In years past, the U.S. Army Marksmanship Unit published weekly reloading “how-to” article on the USAMU Facebook page. Here is a very informative USAMU article the subject of case lubrication. Tasked with producing thousands of rounds of ammo for team members, the USAMU’s reloading staff has developed very efficient procedures for lubricating large quantities of cases. This article reveals the USAMU’s clever “big-batch” lube methods. For other helpful hand-loading tips, visit the USAMU Facebook page on upcoming Wednesdays.

Rapid, High-Volume Case Lubrication

Today’s topic covers methods for quickly applying spray lube to cartridge cases prior to sizing. A typical order for this shop may be 25,000 rounds, so [speeding up] the lubrication process can be a real time-saver. While your ammunition lots probably aren’t this large, the efficient methods discussed here may help save a considerable amount of time over your handloading career. Our case lubrication rates range from 1500-1600 cases per hour, to 2400-2500 cases per hour, depending on caliber.

This shop uses virgin brass, whereas most home handloaders use fired brass, which necessitates some small changes at times. These will be discussed as they arise. Begin with fired brass that has been tumbled clean.

Ensure as much tumbling media as possible is removed from the brass, as when it gets into a size die, it can dent cases significantly. This is a good time to round out dents in the case mouths using a tapered tool to prevent damage from the decapping stem.

First, dump the clean cases into a large box or reloading bin. Shake the bin back and forth so that many cases are oriented with the mouths up. Next, pick up as many cases as is convenient with the mouths “up”, from natural clusters of correctly-oriented cases. With 7.62mm-size cases, this is usually 3-4, and with 5.56mm cases, this can be up to 8-10. Place the cases into the rack slots, mouth-up. Doing this in groups rather than singly saves considerable time. Once these clusters have been depleted, it will be time to re-shake the bin to orient more cases “up.”.

Naturally, adjust the spacing to best fit the calibers you reload. We have found this size … convenient for handling through the various phases of case lubrication/transfer to progressive case feeders for processing. Note that the 1/2-inch angle does not cover much of the critical case area at the base, just forward of the extractor groove, where most re-sizing force will be exerted. As the USAMU uses virgin brass, less lubrication is required for our brass than would be needed for Full Length (FL) sizing of previously-fired brass.

NOTE: The amount applied using our rack is easily enough for our purpose. If using fired brass, be sure to adequately lube this base area to avoid having cases stick in the full-length sizing die.

Using a spray lube, coat the cases adequately, but not excessively, from all sides. Be sure to get some lube into the case mouths/necks, in order to reduce expander ball drag and case stretching/headspace changes. The spray lube this shop uses does not harm primers or powder, and does not require tumbling to remove after lubing.*

Take a close look at the photo above. The USAMU shop uses a common kitchen turntable, which allows the rack to be rotated easily. We place this in a custom-made box which prevents over-spray on to floors and walls.

Angled Box Method for Smaller Cases to be Neck-Sized
A refinement of the above method which especially speeds processing of 5.56x45mm cases is as follows. A small cardboard box which holds about 100 cases is fitted with an angled “floor” secured by tape. With the smaller 5.56mm cases, usually about 8-10 cases per handful can be picked up, already correctly-oriented, and placed into the box together. This prevents having to place them into the rack slots, saving time.

HOWEVER, note that this does not allow nearly as much lube access to the case bodies as does the rack. For our purposes — neck-sizing and setting neck tension on new brass, this works well. If using this procedure with fired brass, take steps to ensure adequate lube to prevent stuck cases.

As always, we hope this will help our fellow handloaders. Good luck, and good shooting!


*A two-part test performed here involved spraying primed cases heavily, while getting more lube into the case mouth/body than even a careless handloader would likely apply. The second part of the test involved literally spraying considerable quantities of the lube directly into the cases, drenching the primers. After a several-day wait to allow the lube to penetrate the primers, they were then fired in a test barrel. All fired normally; no unusual reports were noted. This bolstered confidence that normal amounts of the lube would not adversely affect our ammunition, and we have been pleased with the results over several years.
