When neck-turning cases, it’s a good idea to extend the cut slightly below the neck-shoulder junction. This helps keep neck tension more uniform after repeated firings, by preventing a build-up of brass where the neck meets the shoulder. One of our Forum members, Craig from Ireland, a self-declared “neck-turning novice”, was having some problems turning brass for his 20 Tactical cases. He was correctly attempting to continue the cut slightly past the neck-shoulder junction, but he was concerned that brass was being removed too far down the shoulder.
Craig writes: “Everywhere I have read about neck turning, [it says] you need to cut slightly into the neck/shoulder junction to stop doughnutting. I completely understand this but I cant seem to get my neck-turning tool set-up to just touch the neck/shoulder junction. It either just doesn’t touch [the shoulder] or cuts nearly the whole shoulder and that just looks very messy. No matter how I adjust the mandrel to set how far down the neck it cuts, it either doesn’t touch it or it cuts far too much. I think it may relate to the bevel on the cutter in my neck-turning tool…”
Looking at Craig’s pictures, we’d agree that he didn’t need to cut so far down into the shoulder. There is a simple solution for this situation. Craig is using a neck-turning tool with a rather shallow cutter bevel angle. This 20-degree angle is set up as “universal geometry” that will work with any shoulder angle. Unfortunately, as you work the cutter down the neck, a shallow angled-cutter tip such as this will remove brass fairly far down. You only want to extend the cut about 1/32 of an inch past the neck-shoulder junction. This is enough to eliminate brass build-up at the base of the neck that can cause doughnuts to form.
The answer here is simply to use a cutter tip with a wider angle — 30 to 40 degrees. The cutter for the K&M neck-turning tool (above) has a shorter bevel that better matches a 30° shoulder. There is also a 40° tip available. PMA Tool and 21st Century Shooting also offer carbide cutters with a variety of bevel angles to exactly match your case shoulder angle*. WalkerTexasRanger reports: “I went to a 40-degree cutter head just to address this same issue, and I have been much happier with the results. The 40-degree heads are available from Sinclair Int’l for $15 or so.” Forum Member CBonner concurs: “I had the same problem with my 7WSM… The 40-degree cutter was the answer.” Below is Sinclair’s 40° Cutter for its NT-series neck-turning tools. Item NT3140, this 40° Cutter sells for $14.99. For the same price, Sinclair also sells the conventional 30° Cutter, item NT3100.
Al Nyhus has another clever solution: “The best way I’ve found to get around this problem is to get an extra shell holder and face it off .020-.025 and then run the cases into the sizing die. This will push the shoulder back .020-.025. Then you neck turn down to the ‘new’ neck/shoulder junction and simply stop there. Fireforming the cases by seating the bullets hard into the lands will blow the shoulder forward and the extra neck length you turned by having the shoulder set back will now be blended perfectly into the shoulder. The results are a case that perfectly fits the chamber and zero donuts.”
* 21st Century sells carbide cutters in: 15, 17, 20, 21.5, 23, 25, 28, 30, 35, 40, and 46 degrees. PMA Tool sells carbide cutters in: 17.5, 20, 21.5, 23, 25, 28, 30, and 40 degrees, plus special short-neck cutters.

There is major ammunition shortage right throughout the nation. The unrest and riots in urban areas along with left-wing calls to “defund the police” have caused millions of Americans to be concerned about safety, so they are buying ammo wherever they can find it, online and in stores. Another reason ammo demand is exceeding supply is that 2020 has seen record numbers of first-time gun owners buying acquired rifles, pistols, and shotguns, primarily for self-defense. According to the NSSF, gun sales are up 95% in the first half of 2020 compared to Jan-June 2019. Even more remarkable, the NSSF says ammo sales are up 139% compared to the same time period in 2019. That’s a massive increase.
One ammunition manufacturer, Arizona-based Ammo Inc. has revealed that it has $80 million in unfilled ammo orders. “We’re working right now seven days a week, 24 hours a day in all the manufacturing plants”, Ammo Incorporated CEO Fred Wagenhals told AZFamily.com.
“We just bought 2.8 million dollars worth of machinery and equipment last week to increase our production and increase our volume”, Wagenhals added.
According to GunsAmerica Digest, “Wagenhals attributed the jump in demand to various factors, including COVID-19, the upcoming presidential election, and widespread civil unrest[.]” Wagenhals noted: “As you’ve seen in a lot of cities, the looting and the burning, and I think people are just scared.”
Mark Oliva, NSSF Director of Public Affairs, told GunsAmerica that the spike in demand for ammo mirrors that of firearms, with ammo sales skyrocketing:
“The sale on ammunition goes hand-in-glove with the sale of firearms. NSSF estimates there are more than 5 million people who bought a gun for the first time this year and we’ve recorded more than 13.8 million background checks for the sale of a gun this year. That tops figures for all of 2019 in just the first eight months of 2020. That’s caused an unprecedented demand in the marketplace and we’re seeing this happen everywhere.”
“Ammunition makers are working as quickly as possibly to meet this demand,” Oliva continued. “We’ve seen spikes before and we’ve seen sustained period of demand. This year, though, is unlike any before.”
Ammo Inc.’s STREAK Ammo — Tracers without Heat
Ammo Inc. produces a unique type of STREAK ammo that delivers a tracer-like light trail when fired. Through patented technology, a photo-luminescent coating is applied to the base of the bullet. This is “activated” on firing, allowing the shooter to see the projectile’s path toward its target. STREAK rounds are NON-incendiary. They do not generate heat so they are safe to use in environments where tracers are prohibited or could be a fire hazard. Ammo Inc. says these STREAK bullets are “game-changing” for indoor range use and low-light shooting.
Three new powder lines have been added to the Hodgdon “family” of propellants. Hodgdon Powder Company (“Hodgdon”) has acquired Accurate and Ramshot smokeless powder brands from Western Powders, along with the Blackhorn 209 muzzleloader brand. This acquisition is effective October 1, 2020. Hodgdon will begin shipping these powders immediately to wholesale and retail customers.
This represents a major expansion of Hodgdon’s powder line-up which also includes the popular Hodgdon, IMR, GOEX, and Winchester propellants. Hodgon’s ADI-produced powders, such as H4895, Varget, and H4350 are among the most “in-demand” propellants for precision hand-loaders and competitors.
“This acquisition is another example of our dedication to the handloader and muzzleloader hunter,” said J.B. Hogdon and Bob Hodgdon, co-owners and sons of the founder of the Hodgdon Powder Company. “We have experience in acquiring the IMR Powder brand in 2003, the Winchester Powder license in 2005 and the GOEX brand in 2009 and we plan to put this experience to use in expanding the reach and customer base of the Ramshot, Accurate, and Blackhorn 209 brands.”
Acquisition Expands Hodgdon’s Ballistics Lab Resources
“This acquisition of the Ramshot and Accurate brands further solidifies our portfolio of smokeless brands and products for our handloading end users,” said Steve Kehrwald, president and CEO of Hodgdon Powder Company. “And the addition of Blackhorn 209 to our world-class muzzleloading brands like Pyrodex and Triple Seven uniquely positions us to serve the muzzleloading consumer. With these brands, we also add the capabilities of an additional ballistics lab to continue developing the data our customers demand from our Reloading Data Center and publications like our Annual and Basic Manuals.”
“Hodgdon has always been a strong competitor in the reloading powders industry,” said Doug Phair of Western Powders. “The Hodgdon family has built a robust company. Ramshot, Accurate, and Blackhorn 209 will make excellent additions to the Hodgdon family of powders.”
Olin Corporation announced that, effective 10/1/2020, its ammunition division, Olin Winchester LLC (“Winchester”), assumed full management and operational control of the Lake City Army Ammunition Plant in Independence, Missouri. The U.S. Army selected Winchester to operate and manage the Lake City plant in September 2019. The contract has an initial term of seven years and may be extended by the U.S. Army for up to three additional years. Winchester is now the world’s largest small arms ammunition manufacturer.
Winchester President Brett Flaugher stated: “We were selected to manage the Lake City plant because of our industry-leading capabilities and track record. For decades, we have successfully demonstrated those capabilities in quality, innovation and on-time delivery as well as through our partnership with the U.S. Army in developing solutions that service the U.S. Warfighter. Our team is fully prepared and 100% committed to the safe, reliable and efficient operation of the Lake City plant.”
Currently in its 154th year of operation and 90th year as part of Olin, Winchester has been providing ammunition to the U.S. military since World War I.
About Lake City Ammunition Plant
Lake City Army Ammunition Plant (LCAAP) is a 3,935-acre government-owned, contractor-operated facility in Independence, Missouri that was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S. Army. The Lake City Plant has remained in continuous operation except for one 5-year period following World War II. The plant also serves as a national test center for ammunition performance and weapons firing.
Remington Arms operated the plant from its inception until 1985. Then Winchester took over the facility from 1985-2000. Prior to its acquisition by Northrup Grumman in 2018, Orbital-ATK ran the plant since late 2000, initially as Alliant Techsystems (ATK). In 2019, Olin Winchester, LLC, was selected by the U.S. Army to operate and manage the Lake City Army Ammunition Plant for the next seven years. Winchester took full operational control of the Lake City plant on October 1, 2020.

Cartridges of the World by author Frank C. Barnes was first published in 1965. The 16th Edition is edited by W. Todd Woodard, Editor of Gun Tests magazine and author of several firearms reference books. Frank Barnes (1918-1992) began collecting information on handgun cartridges at the early age of 12, thanks to his father, a police officer. Frank Barnes was an innovative cartridge designer, who invented the original 308 x 1.5″ Barnes, predecessor of the 30BR case.
Before Frank began a law enforcement career, he was a college professor. Frank was also a pilot, and a race-car driver. Learn more about Cartridges of the World (15th Ed.) at www.gundigest.com.

This is a sad story. Remington, America’s oldest continuously-operated gunmaker, has collapsed due to debts and litigation. Through a bankruptcy proceeding, Remington’s product lines and other assets are being acquired by a variety of companies, including Ruger, Vista Outdoor, Sierra, and other large shooting/outdoor industry enterprises. Notably, Ruger will pay $30 million to get the Marlin brand, and Sierra will take over Barnes bullets/ammo business, paying $30.5 million.
The sell-off of Remington assets, specifically product brands, will be going forward through Federal Bankruptcy court, with an order expected Tuesday September 29, 2020. The Shooting Wire reported on 9/28/2020:
Although it won’t be formalized until approved at a hearing scheduled tomorrow (Tuesday, September 29, 2020) in the United States Bankruptcy Court for the Northern District of Alabama, the breakup plan for Remington was filed yesterday. Barring something unforeseen, Remington and its associated companies will be divided among Ruger, Vista Outdoor, Roundhill Group, LLC, Sierra Bullets, Sportsman’s Warehouse, Franklin Armory, and JJE Capital [Palmetto State Armory]. Remington’s Lonoke, Arkansas, ammunition business will go to Vista Outdoor (with SIG Sauer as a backup bid), Sierra Bullets will acquire the Barnes Ammunition interests, Ruger will acquire Marlin, Franklin Armory will assume the Bushmaster brand (and related assets), JJE Capital Holdings will assume DPMS, H&R, Stormlake, AAC, and Parker brands, and Sportsman’s Warehouse will acquire the Tapco brand.
Remington assets will be divided among: Franklin Armory, JJE Capital, Ruger, Roundhill Group, Sierra Bullets, Sportsman’s Warehouse, Vista Outdoor. Roundhill will take over production of Remington firearms which will continue in Ilion, New York.

Even with surging firearms sales in 2020, Remington Arms Company (Remington) found itself in financial trouble — with overwhelming obligations to creditors and investors. Accordingly, on July 27, 2020, Remington filed for Chapter 11 Bankruptcy — the second time in recent years.
Remington, based in Madison, North Carolina, previously filed for Chapter 11 in March 2018. With major loan reorganizations, Remington “emerged nearly two months later, having converted more than $775 million in debt into equity for its lenders.” (Source: Syracuse.com.) However, despite this debt-restructuring, the company struggled with high interest costs and litigation related to the 2012 Sandy Hook school shooting. The perpetrator had a Bushmaster XM15-E2S rifle sold by Remington.
True Velocity is a Texas-based ammo-maker with 145 issued patents on its products and technologies. More than 1 million rounds of True Velocity composite-cased cartridges will be delivered through 2020-2021 to the U.S. Army. This revolutionary new ammo will be tested by the U.S. Army’s Next Generation Squad Weapons program. The advantage of the composite cases, which employ various polymers, is primarily weight savings. True Velocity-made ammo is 30% lighter than conventional ammunition. That means that a typical soldier’s load-out can be reduced by many POUNDS with this innovative ammo. And the military can transport much more ammo with existing vehicles and aircraft.
The company claims: “True Velocity’s precision engineering and manufacturing capabilities allow for substantial improvements in consistency over brass. Our proprietary technology and manufacturing process, combined with progressive process and quality control standards … yields a cartridge of unparalleled performance.” In addition, True Velocity can produce ammo in smaller facilities than a typical large ammo plant. The company states: “The company’s manufacturing capabilities can power customizable and highly-portable ‘cells’, allowing for decentralized and automated ammunition production.”
True Velocity’s modern composite cases withstand temperature changes very well and can function well even in sub-zero environments (however you still may have issues with the powder inside at super-low temps). In addition, the composite cases are 100% recyclable. This can make a difference for shooting ranges and training facilities. One question we have, however, is long-term durability. Brass cartridges can remain strong and functional for decades. Some plastics degrade in just a few years. It will be interesting to see how the True Velocity composite cases hold up over time.
True Velocity is an advanced technology and composite manufacturing company based in Garland, Texas. Founded in 2010, True Velocity has more than 250 patents pending or issued on its products, technology, and manufacturing processes. True Velocity products are manufactured in the U.S. in a state-of-the-art, 66,000-square-foot facility and are currently available to public agencies, with consumer products available soon.

Ever wondered what caused a particular bulge or marking on a case? And more importantly, does the issue make the case unsafe for further use? Sierra Bullets Ballistic Technician Duane Siercks offers some insight into various issues and their causes in two Case Diagnostic articles from the Sierra Blog.
Incipient Case-Head Separation
This is a Winchester .308 Win case that has a real issue. This case has a very obvious incipient case head separation in the process of becoming a complete failure.
This is most commonly caused by over-sizing the case causing there to be excess headspace on the case. After a few firings and subsequent re-sizing, this case is just about ready to come completely apart. Proper die adjustment is certainly a requirement here. Of course this case is not safe to reuse.
Excessive Pressure (Load Too Hot)
If you will notice in the picture of the case rim, there are two pressure signs to notice. First, look at the primer. It is basically flattened to about the max of what could be considered safe. If this was the only pressure sign noted, I would probably be fine with this load, but would constantly keep an eye on it especially if I was going to use this load in warmer temperatures. This load could easily cross into the “excess pressure” realm very quickly.
There is another sign of pressure that we cannot ignore. If you’ll notice, there is an ejector mark apparent that is located over the “R” of the R-P headstamp. This absolutely tells us that this load would not have been in the safe pressure range. If there were any of these rounds loaded, they should not be fired and should be dis-assembled. This case should not be reloaded.
Split Case-Neck
Here we have an R-P .22-250 case that has died the death. Everything looks fine with this case except the neck is split. This case must be tossed.
A split neck is a normal occurrence that you must watch for. It is caused by work-hardening of the brass. Brass cases get harder with age and use. Brand new cases that are stored for a period of time can become hard enough that they will split like this case within one to two firings. I have had new factory loads do the same thing. Then as we resize and fire these cases repeatedly, they tend to get harder and harder. Eventually they will split. The life of the case can be extended by careful annealing practices. This is an issue that would need to be addressed in an article by itself. Of course this case is no longer usable.
In the classes that I teach, I try to use examples like this to let the students see what they should be looking for. As always, if we can assist you, whether you are new to reloading or very experienced, contact us here at Sierra Bullets by phone at 1-800-223-8799 or by email at sierra@sierrabullets.com.
Dented Case Body
Here we have a Lake City 7.62×51 (.308 Win.) case with two heavy marks/dents in the case body.
This one may be a bit of a mystery. It appears as if this case may have been caught in the action of a semi-auto rifle when the firearm jammed or the case failed to clear during the cycling process. I probably would not reload this case just to prevent any feeding problems. This also appeared to be a factory loaded round and I don’t really see any pressure issues or damage to the case.
Multiple Problems — Lake City 5.56×45 unknown year.
This case has suffered multiple failures and cannot be re-used. First its has have a very rounded shoulder that is split. Upon first look it was obvious that this round had been a victim of excess pressure. The firearm (perhaps an AR?) was apparently not in full battery, or there was possibly a headspace issue also. While taking a closer look, the primer was very flat and the outside radius of the primer cup had been lost. High pressure! Then I also noticed that there was an ejector mark on the case rim. This is most certainly an incident of excessive pressure. This case is ruined and should be discarded.
It is very important to observe and inspect your cases before each reloading. After awhile it becomes second nature to notice the little things. Never get complacent as you become more familiar with the reloading process. If ever in doubt, call Sierra’s Techs at 1-800-223-8799.
When neck-turning cases, it’s a good idea to extend the cut slightly below the neck-shoulder junction. This helps keep neck tension more uniform after repeated firings, by preventing a build-up of brass where the neck meets the shoulder. One of our Forum members, Craig from Ireland, a self-declared “neck-turning novice”, was having some problems turning brass for his 20 Tactical cases. He was correctly attempting to continue the cut slightly past the neck-shoulder junction, but he was concerned that brass was being removed too far down the shoulder.
Olin Corporation announced that, effective 10/1/2020, its ammunition division, Olin Winchester LLC (“Winchester”), assumed full management and operational control of the Lake City Army Ammunition Plant in Independence, Missouri. The U.S. Army selected Winchester to operate and manage the Lake City plant in September 2019. The contract has an initial term of seven years and may be extended by the U.S. Army for up to three additional years. Winchester is now the world’s largest small arms ammunition manufacturer.
