No doubt you’ve heard the term “corrosive” used with respect to ammunition. But what exactly is “corrosive ammunition” (and how does it different from non-corrosive ammo)? What is the chemistry that leads to corrosion, and what cleaning procedures should you follow if you shoot corrosive ammunition? Brownells has come up with answers to these and other questions in a helpful TECH TIP video about corrosive ammo.
In this informative video, Brownells gun tech Steve Ostrem explains the primer-related chemistry that makes some ammo corrosive. The video then reviews suggested cleaning procedures you should follow after you have fired corrosive ammo through any firearms.
What Is “Corrosive” Ammunition?
What makes ammo “corrosive”? Generally speaking, primers are the problem. When corrosive ammunition is fired, the ignited primers leave a residue of corrosive salts. Typically these primers contain potassium chlorate, or sodium petrochlorate which, when burned, change into potassium chloride or sodium chloride. Sodium chloride is also known as common table salt.
Potassium chloride and sodium chloride are both very hygroscopic (i.e. they attract water). Because of that, these alkalis are rust generators. When exposed to the hydrogen and oxygen in the air (and moisture) potassium chloride and sodium chloride can form an acid that quickly causes metal rifle parts to rust and pit.
Given a choice, you may wish to avoid corrosive ammo altogether. However, for some types of fire-arms, particularly older military-style rifles, the most affordable ammunition may be corrosive. If you choose to use corrosive ammo, it is important to clean the gun thoroughly after use. After firing, you want to use an element that will neutralize the primer salts. Brownells suggests a water soak (see video above). Alternatively, Windex with ammonia can help neutralize the salts, but that doesn’t finish the job. After the salts have been neutralized and flushed away, basic anti-corrosion protectant (such as Eezox or other gun oil) should be applied to all metal parts.
This video ahows the effects of Corrosive Ammo after one month without cleaning:
To learn more about the proper procedures for cleaning rifles exposed to corrosive ammo, we suggest an article by Paul Markel on Ammoland.com. Markel, host of the popular Student of the Gun TV series, states that: “Windex (with ammonia) is the Corrosive Ammo shooter’s best friend. After you are done shooting your corrosive ammunition for the day, squirt the window cleaner liberally from the chamber down the barrel. Pull the bolt / bolt carrier / op rod if there is one and douse them as well. A couple of old cotton t-shirts will come in handy. A cotton barrel swab is a nice accessory but you can make do with patches. Some folks will rinse all of the ammonia and loosened corrosive salts off with hot water. Others prefer to wipe it all down and let the ammonia evaporate. Either way, once the corrosive salts have been tackled with the window cleaner, it is time for an all-purpose brush (old toothbrush) and some gun oil.” READ Full Article by Paul Markel.

Just in time for the Berger SW Nationals, Berger has released a class-leading new 7mm bullet — the 190 Grain Long Range Hybrid Target (LRHT). The new 190-grainer boasts a “jump-tolerant” hybrid ogive profile along with formed meplat (bullet tip) for more consistent Ballistic Coefficient (BC). In fact, with its new MRT (Meplat Reduction Technology) nose, Doppler Radar testing confirms less than 1% BC variation from bullet to bullet. While a high BC is of course desirable for competitive shooting, shot-to-shot BC consistency is most critical when engaging targets to 600 yards and beyond. The new 7mm 190gr LRHT’s BC numbers are very impressive: 0.751 G1 and 0.384 G7.
Designed for F-Open competition, the 7mm 190gr LRHTs are optimized for cartridges such as .284 Winchester, 7mm WSM, 7mm SAUM, and 7mm Remington Magnum among others.
No you don’t need a new barrel to shoot the 190s. If you are running Berger 184s in a 1:9″ or faster twist you should be fine. Berger states: “The 190gr LRHT is complementary to the industry-leading Berger 184gr F-Open Target bullet with an identical stability factor and improved ballistics when launched from 1:9″-twist barrels.”
Meplat Reduction Technology for More Consistent BCs
Utilizing advanced and proprietary manufacturing processes, Berger’s innovative Meplat Reduction Technology (MRT) applies controlled pressure along the nose of each LRHT bullet. Berger states this delivers ” a homogeneous and repeatable profile for the industry’s most consistent Ballistic Coefficients”.
“With improved MRT consistency contributing to its superior ballistic coefficient and form factor, the 190 is one of our highest performance projectiles to date. They provide minimal dispersion and more hits on target for F-Open competitors, long range shooters and larger capacity 7mm enthusiasts.” said Garett Stoddard, Berger’s Lead Production Engineer.
The new Berger 7mm 190 Grain Long Range Hybrid Target Bullets are shipping now to Berger authorized retailers.
Blue, Red, Green — There are many Progressive Press options on the market…
When you need ammo fast — lots of ammo, it’s hard to beat a progressive reloading press for output. We use progressive presses to load handgun ammo and .223 Rem cartridges for varmint safaris. With good dies, and proper press set-up, today’s progressive presses can produce surprisingly uniform and accurate ammo. No, you won’t see Benchrest Hall-of-Famers loading PPC cartridges on progressives. However, if you need 1000 rounds for your next prairie dog adventure, you should consider getting a progressive. Below you can see a Hornady Lock-N-Load AP configured to load .308 Winchester in bulk.
UltimateReloader.com has published helpful Tips to Optimize Progressive Rifle Loading. No matter whether you have a Red (Hornady), Green (RCBS), or Blue (Dillon) progressive, this article can help you load more efficiently and produce better results. Here are some highlights:
Proper Brass Prep
Just like a good paint job requires good prep work, great rifle ammo requires good brass prep. In order to make sure your rifle loading goes smoothly, make sure to perform the following brass prep steps:
Clean the brass (tumble, ultrasonic, etc.)
Inspect brass for cracks, deep dents, etc.
For military brass: de-prime, ream/swage primer pockets, size with small-base sizer die (small base usually optional).
Measure brass length — if too long, size and then trim.
Final inspection before loading.
Cleaning primer pockets may be something you’ll consider (I don’t clean primer pockets except for rare cases or match ammo).
Smooth and Steady Pace
Since you’re loading rifle ammunition on a progressive, you’re already saving a load of time, so there’s no need to rush things! Attention to detail is super-important for safety and for good results. Always keep an eye on powder level (goes down FAST) and what’s happening at each station.
The Right Press and Press Setup
Look for a heavy-duty, well-built press that will stand up to rifle loading. You’ll also want to make sure your powder measure will have the proper capacity (~25 grains for .223, ~50 grains for 308). If you are bulk reloading, ensure you have enough stations for sizing, charging, powder check, bullet feed, bullet seating, and (optional) bullet crimp. Compare the powder measuring systems, and give careful consideration to the priming process. You want case priming to be 100% reliable. This video reviews the differences between the Dillon XL-650 and the new XL-750 Progressive presses.

This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.
In this Brownells Tech Tip, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Used as a verb, headspace refers to the interference created between this part of the chamber and the feature of the cartridge that achieves the correct positioning. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge.
If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
To learn more, read Brownell’s longer article Headspace Gauges and How to Use Them. Among other things, this explains the relative lengths of “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest: “The GO gauge corresponds to the SAAMI (Sporting Arms & Ammunition Manufacturer’s Institute) minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life from the ammunition re-loader’s standpoint.”
A few years back, Our friend Grant Guess had a “close encounter” with a bad primer. An apparently defective primer caused part of the casehead on one of his rounds to blow out. This, in turn, allowed high pressure gas to vent through the damaged primer pocket. Take a good look, boys and girls. This is yet another very good reason to wear safety glasses. The cartridge was a 6.5-06, handloaded in necked-down Winchester-headstamp .270 Win brass. Grant reports:
“I had a blow through between the primer and the primer pocket today. The action was really smoking and I got a face full of gas. This was a reasonably light charge. Thank God for safety glasses.
I should also mention that it appears there is a 3/64 hole that is halfway between the primer and the primer pocket. Like it burned a small jet hole through both of them.”
Could this happen to you? It just might. On seeing this damaged case, one of Grant’s Facebook friends, Chris D., observed: “Search the internet, you will see a lot of these pin hole ‘in the corner’ failures. Obviously Winchester has some issues with the LR primers.”
Careful Examination Reveals Apparent Primer Defect
After this incident, Grant examined the damaged case: “I pinned the flash hole and it is not over-sized or under-sized. The primer clearly has an area where it had a defect. At [50,000 CUP], it doesn’t take much of a defect to cause issues. There was a slight bit of pucker-factor on the next shot….”
Everyone should have a 9mm Luger (9x19mm) pistol. The 9mm Luger round feeds/cycles great, recoil is moderate, and a vast array of excellent 9mm handguns are available. And, perhaps most importantly, quality factory ammo is affordable. In fact because 9x19mm ammo is produced in such quantity, it is some of the cheapest centerfire pistol ammo you can buy. Today we’ve found some great 9mm Luger ammo deals for you, with big-name factory stuff for under 18 cents per round.
At that price, it may not be worth reloading. Consider this — typical 9mm component costs easily approach fifteen cents per round even with free brass: Bullet ($0.08 – $0.10), Powder ($0.02), and Primer ($0.04). Given the costs of bullets, powder, and primers, it may not be worth reloading 9mm Luger, especially if you value your precious time!
Should You Reload 9mm Ammo? Run the Numbers, Then Decide…
While this Editor reloads almost all his .45 ACP and .44 Magnum ammo, I generally shoot factory ammo in my 9mm Luger pistols. Why? When you give some reasonable value to the time you spend setting-up and operating your reloading press, it is hard to beat factory ammo at around $10 per 50-count box (i.e. $0.20/round). While once-fired 9mm brass is plentiful (and cheap), you can easily spend 15-16 cents per round just on bullet, powder, and primer. So reloading may only save you 4 or 5 cents per round. Hence if you load 200 rounds per hour (including set-up time), you only recoup $8 to $10 per hour (at best) for all your effort. You may decide, as I did, that my time was worth more than that.

22Plinkster Tours CCI/Speer Idaho Factory
Trickshot artist and YouTube host 22Plinkster recently got a chance to tour the CCI/Speer production facility in Lewiston, Idaho. This large plant produces both rimfire and centerfire ammunition. While touring the plant, 22Plinkster was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching.
This revealing video shows all phases of .22 LR ammo production including cupping, drawing, annealing, washing, drying, head-stamping, priming, powder charging, bullet seating, crimping, waxing, inspection, and final packaging. If you’ve got ten minutes to spare, we really recommend you watch the video from start to finish. You’ll definitely learn some new things about rimfire ammo.
Field & Stream Tours Federal Ammo Plant in Minnesota
Note to Viewers — After Starting Video, Click Speaker Icon to HEAR audio!
Last year a Field & Stream writer toured the Federal ammunition production facility in Anoka, Minnesota. This large plant produces both rimfire and centerfire ammunition. While touring the plant, the reporter was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching. Click speaker icon for sound.
The Manufacturing Process for .22 LR Rimfire Ammunition Shooting Sports USA explains: “Rimfire cartridge cases are the oldest self-contained cartridge in existence, having been in continuous production since the mid-1850s. Rimfire cases are drawn from a thin piece of brass and formed with a hollow rim. A priming compound is then forced into the case using centrifugal force, where it is charged with powder and a bullet is seated in the mouth of the case. The case is then crimped around the bullet to ensure sufficient push and pull when the round is fired. When the firing pin strikes the thin brass rim of the case, the hollow rim is crushed and the primer is ignited.” Source: SSUSA.org 9/2/2017.
Buried in CCI Rimfire Ammo
22Plinkster was literally up to his neck in ammo while touring the CCI/Speer Idaho ammo plant. He says: “This was truly a dream come true for me. I can’t thank the people at CCI and Speer enough for allowing me to do this. I couldn’t possibly show everything that went on at the factory. However, hopefully I showed you enough for you to grasp the concept of how rimfire [ammo] is made.”
History — Speer Brothers Brought Ammo Production to Lewiston
Here is an interesting historical footnote. Today’s large CCI/Speer operation in Idaho can be traced back to the companies founded by the Speer brothers. After settling in Lewiston in 1944, Vernon Speer started Speer Bullets. A few years later, in 1951, Vernon’s brother Dick (with partner Arvid Nelson) started Cascade Cartridges Inc., a producer of small-arms ammunition and primers. Yes, as you may suspect, Cascade Cartridges Inc. is now CCI, a Vista Outdoor company, and one of the largest manufacturers of primers and loaded ammunition. Today, the CCI/Speer Lewiston plant produces both Speer bullets and CCI-branded ammunition and primers. Vista Outdoor’s predecessor, ATK, acquired the plant in 2001. Vernon Speer died in 1979, and Dick Speer died in 1994.
We like to use the Birchwood Casey 2″ and 3″ orange “Target Spots” stick-on circles (with diamond centers) for shooting at 300 yards and beyond (photo right). These give you a very precise aiming point if you align your cross-hairs with the corners of the diamond. However, we know that some guys, particularly those whose scopes have “target-dot” reticles, prefer to have a small box for an aim point. In addition, the orange Target Spots are not a true “Day-Glo” color, so they may seem a little dull (low-contrast) when the target is in shadow.
For guys who want an ultra-high contrast target with a square box in the center, Birchwood Casey offers a series of neon green targets with box centers and spike-style extended vertical and horizontal lines (like on a compass). The manufacturer explains: “These adhesive Target Spots come in highly-visible Atomic Green. The crosshair design fulfills the needs of open-sight shooters along with scope users. Easily line up your open sights on the center square or lay the crosshairs along the vertical and horizontal diminishing lines.” You can also rotate the Atomic Green Target Spots 45° to create a diamond center with the crosshairs in an “X” pattern.
We’ve sampled these targets. The Atomic Green background is a true “Day-Glo” color (like safety signs) so these circles appear very bright on a target backer. These work well in low light. We won’t throw away our orange Target Spots, but these Atomic Green circles are a nice option. NOTE: Atomic Green spots are NOT “splatter” targets — a contrasting bright color does NOT appear around your bullet holes.
Multiple Sizes Offered
Birchwood Casey sells the new Atomic green circles in various sizes. You can order a Combo Pack with sixty 1″-diameter spots, thirty 2″-diameter spots, and twenty 3″-diameter circles.
No doubt you’ve heard the term “corrosive” used with respect to ammunition. But what exactly is “corrosive ammunition” (and how does it different from non-corrosive ammo)? What is the chemistry that leads to corrosion, and what cleaning procedures should you follow if you shoot corrosive ammunition? Brownells has come up with answers to these and other questions in a helpful TECH TIP video about corrosive ammo.
