The U.S. Army Marksmanship Unit (USAMU) has published a series of reloading “how-to” articles on its Facebook Page. This post explains how to uniform primer pockets and remove burrs in flash holes. These brass prep operations can help ensure greater consistency, shot after shot. Visit the USAMU Facebook Page for other, helpful handloading tips.
Primer Pocket and Flash-Hole Conditioning
This week, we’ll address a question that frequently arises: “Do you uniform primer pockets and deburr flash-holes?”
As we tailor our handloading methods to the specific needs of each instance, the answer, not surprisingly, is “occasionally!” Generally, the USAMU Handloading Shop does not uniform primer pockets (PP) or deburr flash holes (FH) of our rifle brass. That’s not to say we’re against it — rather, it reflects the very high volume of ammunition loaded, the fact that very few cases are ever re-loaded for a second firing, and the types of brass we use. However, as a need is perceived, we DO deburr flash holes (of which, more later.)
As to the type cases we use, many thousands of our long-range 5.56x45mm cases come to us from the arsenal with the primer of our choice pre-installed and staked in per their usual practice. Obviously, we could not uniform either FHs or PPs on this live-primed brass. However, after careful sorting, inspection and preparation, we do obtain match-winning results with it. Regular readers have seen photos of some of the tiny 1000-yard test groups we’ve fired with weight-selected domestic brass which had neither Primer Pockets uniformed nor flash holes deburred.
Figure 1 shows a fired, deprimed 7.62×51 case with primer residue intact. In Figure 2, the primer pocket has been uniformed to SAAMI specs. Note the shiny finish — evidence of the metal removed to uniform and square the primer pocket.
Shooters who reload their brass several times may decide to uniform PPs and deburr FHs, especially on their “300-yard and beyond” brass. Unlike us, they will be using their cases many times, while the operations are only needed once. Also, most handloaders only process a relatively moderate amount of brass compared to our 20-thousand round lots. Having high quality Long Range (LR) brass helps. Many of the better brass manufacturers form their flash holes so that no burrs are created.
Still, it does pay to inspect even THESE manufacturer’s products, as occasional slips are inevitable. Very rarely, some of these makers will have a significant burr in, say, 1 per 1000 or 2000 cases, and it’s worth catching those. Recently, we began processing a large lot of match brass from a premier manufacturer, and were startled to find that every case had a burr in the FH — something we’d never before seen from this maker. We then broke out the FH deburring tool and went to work.
For those who do opt for these procedures, note that various tool models may have adjustable depth-stops. Pay attention to the instructions. Some flash hole deburring tools which enter the case mouth, not the primer pocket, depend on uniform case length for best results.
Does It Really Make a Difference?
It can be difficult to truly verify the contribution to accuracy of these procedures, particularly when firing from the shoulder, in conditions. Members of this staff, as individual rifle competitors, do often perform these operations on their privately-owned LR rifle brass.
One could ascribe this to the old High Power Rifle maxim that “if you think it helps, then it helps”. Another thought is to “leave no stone unturned” in the search for accuracy.
However, an extremely talented World Champion and Olympic Gold/Silver medalist commented on his own handloading (for International competition, which demands VERY fine accuracy). He noted that he did seem to see a decline in accuracy whenever he did not uniform FH’s, deburr FH’s and clean primer pockets before each reloading; however, with the wisdom of decades’ experience, he also remarked that “It could have been that I just wasn’t shooting as well that day.”
At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, optics, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
1. Brownells — Howa 1500 USA Flag Chassis Rifle, $1299.99
With its “battleworn” stars and stripes Cerakote finish, Howa’s USA Flag Chassis Rifle is an eye-catcher. AND this handsome Howa shoots as good as it looks. This .308 Win rifle features a quality 26″ barrel with factory muzzle brake. The Howa 1500 action cycles very smoothly (better than a Remington or Savage), and this rifle comes with Howa’s fine HACT 2-stage trigger. This rifle includes a 4-16x50mm Nikko Sterling scope mounted to an EGW +20 MOA scope rail, Luth AR buttstock, plus a 10-round detachable box magazine. Howa even includes a Buffalo River swivel bipod with 6″-9″ adjustable legs. With this rig, all you need is ammo! Price is $1299.99 with scope and bipod. NOTE: This is also offered in 6.5 Creedmoor, but that is currently out-of-stock. Check with other vendors.
2. Bruno’s — Nightforce Competition 15-55x52mm Sale, $2160.00
You can’t walk up to any respectable match line and not see a bevy of Nightforce scopes. The Nightforce 15-55x52mm Competition scope is still one of the very best scopes for serious F-Class and long-range competitors. Now Bruno’s is selling the 15-55x52mm NF for $2160.00 — that’s nearly $200 cheaper than other vendors. Bruno Shooters Supply has the Nightforce Competition 15-55x52mm optic as well as countless other Nightforce scopes on sale. Get yours now before prices go back up.
3. Midsouth Shooters Supply — End of Year Clearance Sale
End of year means CLEARANCE at Midsouth Shooters Supply, with prices up to SEVENTY PERCENT (70%) off normal pricing. We’ve posted just a few of the nearly 800 items we found in their clearance section and with prices that can’t be beat it’s worth your time to scour the pages. Head to the Midsouth clearance sale to what you can’t live without before you hit the range again. Note, this End-of-Year Clearance sale ends today December 31, 2018. Don’t hesitate if you see a bargain you like.
The Leupold Ventana S-1 15-45x60mm spotting scope offers a good 15-45X range of power along with a 60mm objective. For a competitor using the spotter mostly for watching mirage and shot markers, this may be all you need in a spotter. And this is compact and easy to transport in a range bag. As one Amazon reviewer said, “TERRIFIC scope! 45X is plenty. Most people with 60X scopes rarely use more than 40X power so I decided to go for this smaller, lighter scope. We used it on wolves in Yellowstone this week at distances of 1/2 to 1 mile. This scope is tack sharp. I was able to compare to Swarovski, Vortex, and Nikon and this Leupold seems just as sharp at a fraction of the price. The amount of eye relief is generous, even better than some of the Swarovskis I looked through.”
5. Midsouth — Hornady L-N-L Auto Progressive Press, $378.99
If you need large quantities of pistol or rifle ammo, it makes sense to get a progressive press. This auto-indexing, 5-station press will give you one loaded round for every complete cycle of the loading handle. We’ve used this Hornady Lock-N-Load AP Progressive press and can confirm that it works well. We actually prefer the rotary powder measure to the sliding powder system on Dillon progressives. We find it much easier to change load weights with the Hornady system (which uses inserts), and it is more precise with certain types of powder. This press also uses convenient quick-change die bushings. Right now you can save $113.00 with the $378.99 sale. NOTE: Press purchasers can get 500 free bullets through the Hornady Rebate Program but that ends 12/31/2018!
6. EuroOptic — Leica CRF 2000-B, $399.00
This may be the best deal we’ve seen on the vaunted Leica 2000-B Laser Rangefinder (LRF) with 7-power optic. This unit is rated out to 2000 yards on reflective objects (in real-world use it will laze a deer well past 800 if you can hold steady). The Leica 2000-B features air pressure and temperature sensors, plus on-board inclinometer. Angle correction works out to 1200 horizontal yards equivalent, with the true hold-over displayed in both MILs and MOA. The compact Leica CRF 2000-B weighs just 6.5 ounces and measures 4.5″ L x 2.25″ H x 1.25″ W. It has a waterproof outer shell.
Are you tired of using pan scales and trickling your charges just to spend a day at the range? Now for under $170.00 you can set your charges and watch them automatically drop quickly and efficiently. The Hornady Lock-N-Load auto charge powder dispenser gives you the confidence and speed whether you’re doing load development or just looking to make some rounds for a day at the range. With this $164.99 sale price, this Hornady dispenser over $90 cheaper than an RCBS Chargemaster Lite.
Have you ever been ready to run to the range and blow off a few rounds only to find that you’re out of targets? If you’re like us that’s one of the most frustrating things that can happen when heading to the club and nobody likes using printer paper and a marker to make a target. Pick up this 100 count set of sight-in targets and you won’t have to run to the store last minute or dig through the range trash cans hoping to find a barely-used target. This is a great value — only 18.4 cents per target!
9. Amazon — Caldwell Zeromax Rifle Rest, $28.99
No this basic, inexpensive rest won’t work for benchrest matches. However, it will suffice to sight-in a hunting or varmint rifle. AND it will do double duty as a cradle for rifle cleaning and maintenance. In fact this Caldwell rest is less expensive than some cleaning cradles than can’t be used for shooting at all. Pick up one of these Caldwell Zeromax Rests for only $28.99 and you’ll have a handy back-up rest you can keep in a vehicle or lend to a friend. Plus, some low-cost modifications can improve the rest’s adjustability. One purchaser noted: “The back foot is just a threaded bolt with a rubber end cap, but it does not turn or move. Changing the elevation with the front two bolts, and keeping everything level can be a challenge, so I added elevation adjustments to the back bolt as well. I did this by taking a bolt spacer from Ace Hardware super glued to a nut, and using that to lift or drop the back. Total cost was about $4.”
Credit Forum Member F-Class John for preparing most of this week’s deals.
Sierra Bullets asked a few hand-loaders to reveal their favorite reloading tool or accessory: “What is your favorite ‘don’t know how you ever lived without it’ piece of reloading equipment?” Some of the answers are listed below. We were interested to see some high-tech, micro-processor items mentioned, such as the AMP Annealer, and the AutoTrickler powder dispenser. Old standbys, such as the rugged RCBS Rockchucker and Dillon 650, also made the favorites list. You can nominate your own favorite reloading hardware in the comments section of the Sierra Bullets Blog.
Sierra Bullets Ballistic Technician Philip Mahin answered: “A comparator gauge to measure from the base of a case to the ogive of the bullet. This bypasses the tip of the bullet, so I can repeat the same seating depth the next time I visit a specific combination.”
Bill, Editor of Rifleshooter.com, answered: “I have so many favorite reloading tools, it’s hard to pick one. But if I had to, it would be my Forster Co-Ax press. I like the ease [with which] you can change dies and that it doesn’t require traditional shell holders. It’s a great tool to have!”
Sierra Bullets Ballistic Technician Duane Siercks answered: “I don’t know that you would actually call this equipment, but the item that comes to mind would be my reloading room/shoot house. I had always had to squeeze everything into a corner or even an unheated shed. After we bought our current house, I built a garage and placed it so that I had a window looking down a 250-yard range. I built a dedicated room with heat and A/C. It contains my reloading bench and a shooting bench. The shooting bench lets me slide open the window and shoot down the range. It is very handy to not have to load everything up to go to the range. It also makes load development a lot simpler and efficient. I don’t know how I ever got along without it.
I also wonder what I did before I acquired the Lyman 1200 DPS Powder Dispenser. This has made the process so much simpler and much easier. I also have a Lee Precison Universal Decapping Die that I would gladly spend the money on again. This may be a small thing, but it certainly is handy. The Lee would accommodate some very large cases that some of the others were too small for.”
Jon Addis answered: “Putting an A&D FX-120i scale with AutoTrickler and Auto-Throw on the bench has changed the way I reload. It’s kernel accurate in about 15 seconds. Saves time and reduces a variable. And of course, the system is made better by the Area 419 Billet Adjustable base for the trickler and Billet Powder Cup.”
This video shows the AutoTrickler V2 and Auto-Throw Combo:
Sierra Bullets Chief Ballistician Tommy Todd answered: “A brass annealing machine and a RCBS Chargemaster complimented with a Sartorious scale.”
Sierra Bullets Ballistician Gary Prisendorf answered: “RCBS Rock Chucker Press, it’s built like a tank, and it will last me a lifetime.”
Sierra Bullets Production Manager Chris Hatfield also answered: “RCBS Rock Chucker single-stage reloading press.”
Jeremy Kisner answered: “My Giraud trimmer has taken [three operations] and combined them into one easy task. I can now size my brass and then sit down and trim, chamfer, and debur to a 0.001″ tolerance in one motion.”
Dan Blake answered: “My Annealing Made Perfect (AMP) annealer. With consistent neck tension being one of the largest contributions to small Extreme Spread on muzzle velocities, I believe this induction annealer is truly the best on the market.”
This manufacturer-produced video shows how the AMP annealing machine operates:
Trevor Aldinger answered: “Area 419 Master Funnel Kit. In the past I’ve used plastic funnels and even other metal ones. This system fits case necks and flows much better than any others I’ve used, and there is no static since it’s metal. We spend a lot of time and money to get precise charges, I don’t want to lose or miss a kernel because of a cheap funnel.”
Tyler Riley answered: “My RCBS bench primer (priming tool). It has a lot more leverage than a hand primer and still has a good feel to how tight primer pockets are. Makes it much easier on my hands to prime large runs, especially new brass with tight pockets.”
Craig Arnzen answered: “My Annealeez [annealing machine] is one of the best tools in my reloading room. Neck tension is SO important, and annealing every firing really helps with that. This is an inexpensive tool that can anneal a lot of cases at once, and help me produce more consistent ammo.”
Josh Temmen answered: “Time is critical for me so my RCBS Chargemasters are indispensable (pun intended.) They cut down on time at my reloading bench while maintaining the weight tolerances required for long range shooting.”
Josh Bartlett answered: “I have my Dillon 650 set up with Whidden floating tool heads to do decapping and sizing on my match ammo. The case feeder and progressive function of the press save me a TON of time when doing lots of several hundred rounds.”
Ryan Brandt answered: “… A quality set of calipers. My reloading room is full of very nice equipment but little does more to satisfy my perfectionism than a good check with the calipers.”

8. CDNN — Ruger LCP .380 ACP, Just $169.99
If your carry gun is too big and bulky, you probably won’t carry it, which sort of defeats the whole purpose. The Ruger LCP is light (9.6 ounces) and compact (5.16″ OAL), so you’re more likely to carry it regularly. The little LCP is small enough to fit in a pocket. The .380 ACP cartridge is not as powerful as a 9x19mm or 40 S&W to be sure, but when your life is on the line, a small gun is certainly better than no gun. For those looking for a very light-weight, easy-to-conceal handgun, this little Ruger is a solid choice. Owner reviews have been positive and the $169.99 price is as cheap as you’ll ever find for a major manufacturer’s pistol. If you can live with the bright yellow frame, this is a steal.
A clean gun is a happy gun and since patches are the core of any cleaning regimen why not grab some great patches for a great price? Amazon sells 1000-count packs of Boosteady Professional Cleaning Patches starting at just $8.99 for 1″ square patches — a great bargain for 1000. Now you won’t feel so bad running a few extra patches every time you clean just make sure you got the last bit of crud out. Boosteady patches are very highly rated by purchasers and come in 1″ square ($8.99), 2″ square ($11.99), and 2.5″ square ($13.99) sizes, inside a convenient box.
10. Amazon — Two Rolls of 3″ Neon Target Stickers, $12.99
We like these bright, Neon EasyShot 3″ target stickers. They are big enough to see easily at 600 yards, giving you a 1/2 MOA target center at that distance. For $12.99 at Amazon.com, you get 250 3″-diameter self-adhesive centers (125 targets per roll) that stick to almost any surface The high-contrast fluorescent red/orange color provides an excellent HI-VIZ aiming point, along with good contrast for bullet holes that fall within the 3″ circle. To help line up your reticle cross-hairs, the target centers feature black markers at 3, 6, 9, and 12 0’Clock. NOTE: These stickers qualify for FREE Shipping.
The folks at PMA Tool, makers of arbor presses, neck-turning tools, and other case-prep tools, offered some good advice about case trimming on the PMA Tool Website. Here we reprint a PMA article that explains case trimming basics and helps you choose the right case-trimming tool for your needs.
Case Trimming Basics
Trimming the cartridge case to the proper length is a crucial step in case preparation that should not be overlooked or underestimated. The cartridge case or the rifle can be damaged, or even worse you get badly injured. In most instances cases should be trimmed after firing and sizing. Trimming new brass is necessary for a lot of wildcats and can be beneficial in some instances, but by and large, trimming new brass is not necessary for most situations (unless you are neck-turning). Cases should be trimmed after you have sized the case, because the expander ball on the decapping pin can (and will) stretch the neck. Those of us who neck size should get into the habit of trimming after sizing as well. This is a good rule of thumb to go by, and hopefully it will keep you safe during the reloading and shooting process.
There are so many case trimmers out there that work, deciding which one is right for you can be confusing. Even though I have trimmed thousands of cases, using about every method possible, I can’t answer the question of what case trimmer is right for you because of all the variables that may be involved. I can, however shed some light on the subject.
The two most popular designs of trimmers either index (1) off the base or the head of the case, (2) off the shoulder or datum line of the case. There are pros and cons to each and it all depends on what you are willing to live with.
Indexing off the Base (Case Head)
Let’s talk about the first one I have listed, indexing off the base, or the head of the case. The pros to this method are that you can achieve a very accurate over all length and that is after all, what it is all about. The cons to this method are that you can get some variation doing it this way. Let me explain, the base is not always square to the body or can be damaged during firing especially if it is fired through a military style rifle with a very aggressive ejector. These cases should be discarded, but sometimes they can be overlooked. This condition can lead to an over all length that is incorrect. The case head being out of square will be corrected upon firing, however that case will wind up being shorter than the rest of your cases, possibly creating a difference in the neck tension on the bullet. The more you can do to eliminate variables in your reloads the better off you are going to be. This method can also be very slow, and if the user gets careless the result will be a inconsistent over all length.
Indexing off the Shoulder (Datum Line)
The second method I mentioned, trimming off the shoulder or the datum line of the case, has its pros as well. I have found this to be the quickest of the methods and very accurate as well. After the case has been sized through the die the dimensions (particularly the headspace) of the cases are usually very uniform and exact, this allows the case to be trimmed by indexing off the shoulder. This method can be done very quickly, by hand, or by powering either the case, or the trimmer. You also don’t have to worry about the case heads being out of square with the body using this method. Generally the trimming time is cut in half, and this leads to greater focus on the job, without becoming careless. [Editor’s Note: The World’s Finest Trimmer (WFT) is one power device that indexes off the shoulder datum. It works fast and is very precise. The updated WFT 2 Model and WFT Big Boy feature interchangeable trim chambers to work with multiple cartridge types.]
Summary
The choice is yours to make. I hope that this was some help to you, whether you are looking for your first trimmer or looking to replace the trimmer you have. Just remember to always put safety first and accuracy second, and you will start making little bug holes in no time.
Story Tip by EdLongrange. User Submissions are welcome.
Harrell’s Precision sells “semi-custom” full-length bushing dies for the PPC and 6BR chamberings. While the Harrell brothers do not cut the die to spec, they carry a large selection of dies made with slightly different internal dimensions. When you send in your fired brass, the Harrells choose a die from inventory with just the right amount of sizing (diameter reduction) at the top and bottom of the case. Given the quality, and precise fit, Harrell’s full-length dies are a good value at $75.00 plus shipping.
Bump Measuring Collar
The Harrell brothers provide a nice bonus item with each full-length die — a neat, little shoulder bump measuring device as shown in the photo at right. Hornady/Stoney Point sells a stand-alone tool that does the same job, but the Harrell’s bump collar is simpler and faster. To measure your shoulder bump, simply place the Harrell’s bump collar over the front of your deprimed case (before sizing) and measure the OAL with your calipers. Then size the case in your full-length die, replace the collar and repeat the measurement. You want to set your die so the shoulder moves back about .001″ to .0015″ for most applications. (With semi-auto guns you may want more bump.)
Hodgdon has released its 2019 Reloading Manual, the 16th Annual Edition of this valuable reloading resource. This new manual contains data for Hodgdon, IMR and Winchester Smokeless Propellants in more than 5,000 loads, with updates for 17 rifle and pistol cartridges. Using this resource, handloaders can now find data for the new 224 Valkyrie and 6.5 PRC cartridges. Along with comprehensive load data, the 2019 Hodgdon Annual Manual offers authoritative articles by leading gun and outdoor industry writers, working with the editors of Shooting Times magazine.
“The Annual Manual is our printed yearly update for the ardent handloader,” said Ron Reiber, lead ballistician for Hodgdon. “We believe one of our competitive advantages is providing cutting-edge data on all our propellants. Our customers know they can look to Hodgdon to be first to supply this information on hot, new cartridges and newly-introduced powders.”
CLICK HERE to order the 2019 Hodgdon Annual Manual from the Hodgdon website for $12.99 (shipping included). You can also purchase the Annual Manual wherever popular magazines are sold.
H4350 and Varget In Stock Now at Many Vendors
In 2017 Hodgdon celebrated its 70th Anniversary. At SHOT Show 2017 talked with Chris Hodgdon. Chris was proud to note that his family-owned company is now marked its 70th year in business. The company has been very successful, but sometimes that means supply can’t catch up with demand with some of the most popular powders, such as Hodgdon H4350, which is extremely accurate and also temp-stable. Chris said: “Getting more H4350 to our customers is one of our top priorities. With the booming popularity of the 6.5 Creedmoor and other similar cartridges, there is a lot of demand for that powder.” Supply has definitely increased this year. Yes, H4350, in both 1-lb and 8-lb containers, is in stock right now at Bruno’s, Graf’s, Midsouth, and Powder Valley.
We also discussed the continued popularity of Varget, which also became more readily available this year. It is still one of the very best choices for a wide variety of cartridges, including the .308 Win (just look at the groups on our X-Max for Xmas story). Chris said that Varget users may also want to try IMR 8208 XBR. Chris observed: “I think IMR 8208 XBR is one of the very best powders we make. It is accurate, temp-stable, and it meters very well because the kernels are very small. The guys who try 8208 have been very happy.”
We concur with Chris — we’ve used 8208 XBR in a .308 Win and it shot exceptionally well. It is definitely “match-ready” powder for cartridges that like a medium burn-rate powder, such as the .308 Winchester, 7mm-08, and 6mmBR Norma.
Do you need a heavy-duty, single-stage press, or a high-output progressive with precise powder measure?

Clearance Check — Remove the seating stem and drop a bullet into it. The farther down the ogive or nose-cone the step recess grips the bullet, the better. If it’s only pressing down against the bullet tip, a crooked seat is assured, along with inconsistent seating depth. — Glen Zediker
Some folks acquire a new seating die and then are surprised to find their hand-loads show crooked bullets and/or inconsistent seating depth. The problem could be a mis-match between the bullet and the die’s seating stem. In some case, particularly with long, streamlined bullets, the bullet tip can actually touch the bottom inside of the stem. This can cause a variety of problems, as Glen Zediker explains…
Invest in a Good Seating Die Reloading Tip by Glen Zediker
The bullet seating operation is the “last thing” that happens and it’s also the one thing that can corrupt the care and treatment given to the quality of the loaded round prior. A sleeve-style seater, well-machined, goes a whopping long ways toward preserving alignment, and, therefore, concentricity. Also make sure that the stem in yours comes to rest well down onto the bullet ogive, and, above all else, is not contacting the bullet tip! That will wreck a round.
If you have this problem, you should contact the die maker — some will offer a different seating stem expressly designed for longer, pointier bullets. This “long bullet stem” will normally drop right into your existing die. If you plan to run long, VLD-style bullets you should request the special seating stem right from the get-go.
Powder Moisture Content — Did You Know?
Variations in moisture content change the burning rate of a powder and thereby chamber pressures and muzzle velocity. The moisture content of the Vihtavuori N100 and N300 series powders is usually around 1%, while the N500-series’ normal moisture content is 0.6% because of the added nitroglycerine.
So what difference does moisture content make? Here’s an example. In a test, a [Vihtavuori] powder sample was dried by heating it, losing about 0.5 % of its weight. Cartridges were then loaded with the dried powder and fired using a pressure gun. Chamber pressures and muzzle velocities produced by these special cartridges were compared to those produced by cartridges loaded with untreated powder. (The powder charge and bullet were of course the same in both sets of cartridges.)
After Powder Drying:
Pressure Increased 11% from 320 MPa to 355 MPa
Velocity Increased 2.6% from 2526 to 2592 FPS
Comparing results showed chamber pressures increased from 320 MPa to 355 MPa with the dried powder, and the muzzle velocity increased accordingly from 770 m/s to 790 m/s (2526 to 2592 FPS). And note, this is only one example, of one caliber and loading. The difference might be much higher depending on the cartridge and loading combinations.
Recommendation: Store powder below 68°F in 55-65% humidity.
What does this tell us? Well, it seems we need to forget the old saying “Keep your powder dry”! Instead, focus on proper powder storage, at a temperature below 20°C/68°F and humidity between 55 and 65%. Safe reloading everybody!
