LEE Breech Lock Hand Press — Versatile and Portable

Lee breech lock hand press kit
The LEE Hand Press Kit comes complete with: Breech Lock Hand Press, Ram Primer fittings, Powder Funnel, Case Lube, and one Breech Lock Quick Change Bushing.

The LEE Breech Lock Hand Press is a useful addition to any reloader’s tool collection. This Hand Press allows you to resize brass or seat bullets while at the range or away from your loading room. No it won’t replace your Co-Ax or Rockchucker, but this is a handy piece of gear. And it’s very affordable. Midsouth sells the LEE Breech Lock Hand Press Kit, with everything shown above, for $68.99. Or you can buy just the Hand Press by itself for $52.99 at Titan Reloading. That’s a great deal.

Lee breech lock hand press kitLEE Hand Press Quick-Change Die Functionality
This LEE Press includes the Breech Lock Quick-Change Die Feature, so you can instantly change dies with just a twist of the wrist. One Breech Lock Quick Change Bushing is included. The Breech Lock Hand Press is light and compact. It tips the scale at a mere 1 3/4 pounds and overall product length is 11.5″. Note: the maximum overall length cartridge the LEE Hand Press can accept is 3.650 inches.

While we don’t recommend the Hand Press for major full-length sizing chores, it does a good job seating bullets. This makes it a handy “field expedient” tool when doing load development at the range. For example you can experiment with seating depth by loading a batch of cartridges at home with the bullets deliberately seated long. Then, at the range, you can re-seat the bullets progressively shorter (in a series of rounds), until you find the optimal Cartridge OAL.

LEE’s Hand Press is also great for decapping operations. One verified buyer reports: “I mostly use it for decapping while watching TV, with a universal decapper die. Of course it is also useful for other operations. I wouldn’t love sizing large rifle cases with it, but if you’ve prepped your cases on a bigger press you could comfortably take it to the range for load development, one round at a time, working right there at the line instead of making a bunch of loads at home that you’ll have to disassemble later. It’s smaller and more lightweight than it looks[.]”

Using LEE Hand Press to Load at the Range
To learn more about using the LEE Hand Press in the field with a compact scale, read Reloading Without a Bench on GunsAmerica.com. Author Christopher Mace explains: “Whether you want a better way to do load development, the capability to reload out of your ‘bugout bag’, or you’re short of space but wanting to get into reloading, the LEE Loaders and the LEE Hand Press offer you some options.”

NO-LEAD Solvent for Rimfire Rifles and Centerfire Pistols

Suhl Rimfire Benchrest indoor cleaning
We have used NO-LEAD Cleaner in rimfire benchrest rifles similar to this modified Suhl 150-1. It helped restore accuracy with minimal brushing.

NO-lead brushless lead remover Wipe-out Sharp Shoot-rMade by the same smart folks that created Wipe-Out™, and Carb-Out™, NO-LEAD Brushless Lead Remover™ really works. Honest. If you are an active rimfire shooter, or if you shoot cast lead-alloy bullets in centerfire rifles and pistols, you should try this product. We now use NO-LEAD in our rimfire benchrest rifles, and in some centerfire guns that receive a steady diet of soft-alloy cast bullets (90%+ lead). (With rimfire guns, you don’t need to use NO-LEAD very often — maybe every 300-400 rounds unless you have a real fouler of a barrel.)

If you’ve got stubborn lead fouling in a rimfire barrel, or on a pistol’s muzzle brake/compensator, you should definitely give this stuff a try. We don’t know how but it does soften lead deposits. The manufacturer says you don’t need brushes, but we found that a bit of brushing (after NO-LEAD application) can help remove more serious lead build-up.

Yes we were surprised to find a lead remover that really works. We tried a half-dozen other lead “cleaners” that promised to dissolve lead and most of them, we discovered, are nearly useless. There’s a reason for that, as the lead alloys used in bullets don’t react to typical petrochemical-based solvents. It took the Wipe-Out chemists over five years to perfect this water-based solution that really does dissolve lead.

NO-LEAD Cleaning Procedure — Read Carefully
NO-LEAD Lead Remover is a clear, red gel that is easy to apply. Just swab it in your bore (or on muzzle brakes) with wet patches or bore mop and let it sit for a few minutes. (The manufacturer says you can leave the NO-LEAD for up to 20 minutes, but that long of a dwell time does not seem necessary with our rimfire barrels.) When it contacts lead it will start to foam and you’ll see that the NO-LEAD solvent turns a pastel pink when it dissolves lead. The pink comes from the formation of lead oxide. After the recommended dwell time, simply patch out the dissolved lead deposits (you can also use a nylon brush for stubborn lead build-up).

NOTE: After cleaning, it is very important that you get all the NO-LEAD out of your barrel, and neutralize it. We recommend following the application of NO-Lead with Wipe-out or Patch-Out to neutralize the NO-LEAD, clear the bore, and remove residual carbon and copper fouling. If you don’t have Wipe-Out or Patch-out, flush the barrel thoroughly with Rubbing Alcohol or even a solution of Dawn dish detergent — then re-oil the bore.

Be Sure to Neutralize NO-LEAD After Use
Remember that N0-LEAD is a strong, slightly acidic chemical that needs to be neutralized after use. If you leave it on a nice, blued barrel for too long, it can harm the bluing. NO-LEAD will remove all the surface oils from the barrel bore. For this reason it is recommended that you neutralize NO-LEAD with Wipe-Out, or Patch-Out, which both contain effective corrosion inhibitors. If you don’t have those products, once you’ve flushed the NO-LEAD with something like rubbing alcohol, then follow with a gun oil. Caution: A petroleum-based gun oil will NOT, by itself, neutralize NO-LEAD. You need to neutralize first, then apply the corrosion inhibitor (or do it all in one step with Wipe-Out or Patch-Out).

Where to Buy NO-LEAD Lead Remover
NO-LEAD Lead Remover costs $18.55 for an 8 oz. squeeze bottle with a flip-top spout. This product is sold directly by Sharp Shoot-R Precision Products through Sharpshootr.com, or you can purchase NO-LEAD through many other online vendors. For more information, send an email via the Sharp Shoot-R Contact Form or or contact SharpShoot-R at (785) 883-4444. You can ask for Terry Paul, Sharp Shoot-R’s owner and the master chemist who developed the NO-LEAD formula.

Saturday Movies: Single-Stage Reloading Press Video Reviews

RCBS Rock Chucker MEC Marksman Lyman Brass smith ideal Frankford co-ax forster Hornady iron Lee Classic Cast Breech Lock Press

Hand-loaders have never had so many great choices in single-stage presses, with many different configurations and features. There are classic O-Frame presses, Coax-style presses, Open-front presses, Pyramid presses, and compact C-Frame presses. Here is our 2019 Single Stage Press Showcase with products from Forster, Hornady, Lee, Lyman, MEC, and RCBS. We’ve included short videos showing the features of these reloading presses.

If you are shopping for a new press you should look at the various features of each. You may prefer something classic like a Rock Chucker, or the innovative open-front MEC. If you are looking for a compact press to use at the range, the Lyman C-Frame is very impressive for the price. And the Forster Co-Ax remains a great addition to any loading room.

MEC Marksman Single-Stage Press

If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. With a $245.49 street price, the MEC Marksman press now costs more than an RCBS Rock Chucker Supreme press, but the MEC offers some distinct advantages — such as an open front plus a floating shell-holder system.

MEC Marksman Press Gavin Gear single stage open front press die caddy accessories

Our friend Gavin Gear of UltimateReloader.com got his hands on a MEC Marksman press and put it through its paces. He came away impressed with the product, saying it delivers excellent performance, and has many impressive features. Gavin tells us: “Cast iron tools and machines are a lifetime investment. The made-in-USA MEC Marksman features ductile cast-iron construction, an open-front frame design for easy cartridge access, a new floating shell-holder design with a unique retention system, and ambidextrous handle setup.” MEC also offers a wide selection of accessories for the Marksman press, including a press riser/mount, shell-holder caddy, and die trays.

Forster Co-Ax Press

co-ax forster Hornady reloading single-stage PressIf you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.

In recent years, Forster Co-Ax® presses have been somewhat hard to find, as demand has out-stripped supply. The Co-Ax has many dedicated fans, given its unique features, such as the floating case-holder jaws, and easy, rapid slide-in/slide-out die placement. We’ve also found that Co-Ax presses load very straight ammo and we like the ability to switch between short handle (good for bullet seating) and long handle (ideal for heavy case-sizing tasks). We also think the Forster Co-Ax has one of the best spent primer capture systems on the market — a straight drop into a removable plastic cup. Simple and it works.

Lyman Brass Smith Victory Single-Stage Press

Lyman Brass Smith Victory Single stage press videoLyman’s sturdy Victory Single-stage Press is a full-size unit that competes with the RCBS Rock Chucker Press. With beefy cast iron construction, the Victory’s strength and leverage rivals the Rock Chucker. The press operates smoothly and the handle can be mounted on either side.

If you like to prime cases using a press, this Victory press has a priming system that’s much easier to use than the RCBS Rock Chucker system. The priming tube is right up front, with multiple primers loaded vertically in a tube. Simply push the shuttle at the button of the tube to advance the primer into place.

For convenience, the entire primer-loading system can also be removed so it doesn’t interfere with case and bullet-handling operations. We generally prefer to prime cases separately using a dedicated hand- or bench-mounted tool, but the Victory press does the job nicely.

Overall, the Victory is a great value in a full-size “O-Frame” press with sturdy construction and a solid Lyman warranty. It is available now for $208.52 on Amazon.

RCBS Rock Chucker Supreme Single-Stage Press

RCBS Rockchucker Rock Chucker Supreme Single Stage reloading press Bruno ShootersNearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.

Some people may not know that the Rock Chucker offers a secondary 1 1/4″ x 12 thread for shotshell reloading dies and Piggyback 3 upgrade. The Rock Chucker Supreme retails for $213.79 now at Powder Valley and qualifies for a $35 RCBS rebate, lowering your net cost to $178.79 (after rebate). The RCBS Rock Chucker is definitely a quality product that can last a lifetime. For heavy-duty sizing chores this remains one of the best choices in single-stage presses. This is a good time to buy a RCBS press with the current RCBS Rebate Program.

Lyman Brass Smith Ideal C-Frame Compact Press

The Lyman Brass Smith Ideal Press is a very affordable, cast iron C-Frame reloading press. We think it is the new “class leader” in compact presses. This works great as a secondary press for your reloading room or a small press you can take to the range. The large front opening allows you to access the shell holder without hitting the support bar on other types of presses. Unlike other compact presses made from aluminum, Lyman’s Ideal press is cast iron so it is rigid and strong. The high-quality steel ram is one inch in diameter. The Brass Smith is a true ambidextrous press that can be accessed from either side and mounted the same. This is a great choice for a second, auxiliary press for depriming and bullet seating. It is now just $119.66 at Precision Reloading.

Hornady Iron Single Stage (Open-front) Press

In this “Reloading with Rosie” video, the attractive female host loads some ammo using the Hornady Iron Press. With a beefy, pyramid-style cast-iron frame with an open front, this press offers some advantages over a traditional “O-Frame” type press. Access is considerably easier, for one thing. And the top of the press includes slots to hold dies and tools — that’s really a very nice feature that saves time. Also an optional “automatic” priming system shuttles primers from a vertical tube in the back to the shell-holder in the front. That’s clever. Over all the Iron Press is a nice piece of engineering — good job Hornady. It is offered for $314.78 at Precision Reloading.

Lee Classic Cast (Iron) Breech Lock Press

Lee Classic Cast Breech Lock PressThe Lee Classic Cast Breech Lock Press offers excellent value for the money ($190.99 at Midsouth). Based on the proven design of the Classic Cast press, the updated Breech Lock series adds the quick-change die bushing and an improved primer drop system. This press is strong, with cast iron frame, all-steel linkage, and 12 square inches of ram bearing surface.

Lee says this press has the “largest opening and the longest stroke in the industry” among O-frame type presses. The handle can be mounted on either side. We love the fact that the handle ANGLE can be adjusted, as well as the lever arm length — that allows you to adjust travel and leverage to suit your preference. Smart engineering.

The new spent primer drop features a large-diameter hollow ram with clear hose that drops primers straight to a bin — that’s simple and effective. The press is very rigid and the base is wide enough for good stability. We have one of these Classic Cast Breech Lock Presses in our reloading room and it works well.

Tech Tip: Better Viewing with Magnifier for Balance Beam Scales

RCBS 10-10 Scale RCBS balance beam magnifier weigh powder reloading

When he measures his loads or sorts bullets by weight, Forum Member Boyd Allen often employs his trusty RCBS 10-10 balance beam scale (although he does have handy digital scales as well). He finds that the balance beam scale works predictably, time after time, and it doesn’t suffer from the drift and calibration issues that plague some of the less expensive electronic scales on the market.

RCBS Balance Beam scale 10-10 magnifier weigh powder reloading

To make it easier to see the balance point, Boyd has adapted a magnifying glass with a mirror. This makes the end of his balance beam easier to view from his normal position on the bench. Boyd explains: “This set-up uses a cheap magnifier with positioning arms that was probably designed to hold and magnify small objects while soldering them. I think that it came from Harbor Freight many years ago. The mirror lets you look at the scale as if is was at eye level, and of course the magnifier makes the image easier to see.”

If you have a balance beam scale, we suggest you try this simple enhancement. We predict you’ll find the magnifier speeds up the process with enhanced assurance of your load weight.

Single Stage vs. Progressive Presses — Function and Safety

Accurateshooter.com USAMU progressive press reloading

For many years, the U.S. Army Marksmanship Unit (USAMU) regularly published reloading “how-to” articles on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.

USAMU Reloading

Progressive Press Safety Considerations

by USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.

usamu progressive reloading press RCBS

Worse yet, several different handloading operations would be occurring at different stations on the progressive press at the same time. It takes an experienced operator to keep track of, and truly understand the significance of, all those potential mini-problems. Loading without this experience is a recipe for potential disaster – such as a double powder charge (especially with pistol cartridges) dropped while the loader was attending to some other function, etc. Progressives are an animal unto themselves, and while they offer many benefits, they do take some getting used to – even by experienced handloaders!

ILLUSTRATIVE HORROR STORY
Here, enter a 40-year veteran handloader who decided to jump onto the progressive bandwagon late in his career, having used only single-stage presses all his life. A High Master NRA High Power Rifle competitor, he had no background in competitive pistol shooting, where historically most progressive presses are found.

Experienced Action Pistol shooters have typically encountered multiple episodes in which shooters “skipped” a powder charge for some reason, leading to a squib round and a bullet possibly lodged in the bore. Thus, at matches, it’s reflexive for them to yell “STOP!” in unison if they see a shooter get a “click” vs. a “bang”, and rack the slide to keep firing. This writer has personally seen several pistols saved in just such scenarios over the years.

Click No Bang — What NOT to Do
Our High Master set up a popular progressive press and began turning out .223 Rem 100-yard practice ammo with abandon. He was using a moly-coated 52gr match bullet and an economical, fast-burning surplus powder that gave great accuracy. Once on the range, he began practicing strings of rapid-fire. All was well, until he heard “Click!” rather than “Boom”.

Lacking the above experience or onlookers to halt him, he reflexively operated the charging handle on his expensive, custom NM AR15 Service Rifle, and the next trigger squeeze reportedly registered on seismographs over at least a three-state radius. He sat, uninjured but bewildered, until the hail of expensive bits and pieces quit raining down around him.

When the smoke cleared, he immediately cursed the horrid, evil, demonically-possessed progressive press for this, his first-ever reloading mishap. His $1400 NM upper was ruined, but thankfully, his $800 pre-ban lower… and he had escaped injury.

This tale is told not to discourage the use of progressive presses, but to emphasize the need to EASILY and IMMEDIATELY KNOW what is happening with the press at each station, every time the handle is cranked. Not to do so is, as they say, “bad ju-ju.”

It illustrates why we at the USAMU Handloading Shop agree in recommending that new handloaders should begin with a single-stage press. Once one thoroughly learns the steps in each phase of handloading by repeated experience, then one will be qualified to move on to a progressive press.

The single-stage press will REMAIN virtually indispensable for one’s entire handloading career, even after having purchased a progressive press (or two). There are endless small projects that are best handled on a single-stage press, and a poll of USAMU’s Handloading staff reveals that not one would willingly be without his single-stage press, despite owning at least one progressive.

Bullet Concentricity and Alignment — Key Things to Understand

Sinclair concentricity 101 eccentricity run-out reloading plans

Sinclair International reloading toolsSinclair International has released an interesting article about Case Concentricity* and bullet “run-out”. This instructional article by Bob Kohl explains the reasons brass can exhibit poor concentricity, and why high bullet run-out can be detrimental to accuracy.

Concentricity, Bullet Alignment, and Accuracy by Bob Kohl
The purpose of loading your own ammo is to minimize all the variables that can affect accuracy and can be controlled with proper and conscientious handloading. Concentricity and bullet run-out are important when you’re loading for accuracy. Ideally, it’s important to strive to make each round the same as the one before it and the one after it. It’s a simple issue of uniformity.

The reason shooters work with tools and gauges to measure and control concentricity is simple: to make sure the bullet starts down the bore consistently in line with the bore. If the case isn’t properly concentric and the bullet isn’t properly aligned down the center of the bore, the bullet will enter the rifling inconsistently. While the bore might force the bullet to align itself with the bore (but normally it doesn’t), the bullet may be damaged or overstressed in the process – if it even it corrects itself in transit. These are issues we strive to remedy by handloading, to maintain the best standard possible for accurate ammunition.

The term “concentricity” is derived from “concentric circle”. In simple terms it’s the issue of having the outside of the cartridge in a concentric circle around the center. That goes from case head and center of the flash hole, to the tip of the bullet.

Factors Affecting Concentricity

The point of using this term is to identify a series of issues that affect accurate ammunition. Ideally this would work best with a straight-walled case; but since most rifle cartridge cases are tapered, it equates to the smallest cross section that can be measured point by point to verify the concentric circle around the center. For the examples below, I’m working with .308 Winchester ammo.

Concentricity run-out cartridge case
Figure 1: The cartridge.

Concentricity run-out cartridge case
Figure 2: Centerline axis of the case, extending from flash hole to case mouth.

The case walls have to be in perfect alignment with the center, or axis, of that case, even if it’s measured at a thousandth of an inch per segment (in a tapered case).

Concentricity run-out cartridge case
Figure 3: Case body in alignment with its axis, or centerline, even in a tapered case.

The case neck must also be in alignment with its axis. By not doing so you can have erratic bullet entry into the bore. The case neck wall itself should be as uniform as possible in alignment and in thickness (see the M80 7.62x51mm NATO cartridge in Figure 5) and brass can change its alignment and shape. It’s why we expand the case neck or while some folks ream the inside of the neck and then turn the outside for consistent thickness, which affects the tension on the bullet when seated.

Concentricity run-out cartridge case
Figure 4: Neck in alignment with center of the case axis.

Concentricity run-out cartridge case
Figure 5: Variations in case neck wall thickness, especially on some military brass, can cause an offset of the bullet in its alignment. This is an M80 ball round. Note the distinct difference of the neck walls.

Having a ball micrometer on hand helps, especially with military brass like 7.62x51mm in a semi-auto rifle, where there are limits as to how thin you want the neck walls to be. In the case of 7.62 ball brass you want to keep the wall to .0145″.

Concentricity run-out cartridge case
Figure 6: A ball micrometer like this RCBS tool (#100-010-268) can measure case neck thickness.

Turning the outside of the neck wall is important with .308 military cases regardless of whether you expand or ream the neck walls. There are several outside neck turning tools from Forster, Hornady, Sinclair, and others. I’ve been using classic Forster case trimming (#100-203-301) and neck turning (#749-012-890) tools for 40 years.

Bullet Run-Out
The cartridge, after being loaded, still needs to be in alignment with the center of the case axis. Figure 7 shows a bad example of this, a round of M80 ball. A tilted bullet is measured for what’s known as bullet “run-out”.

Concentricity run-out cartridge case
Figure 7: An M80 round with the bullet tilted and not aligned with the axis. This will be a flyer!

Run-out can be affected by several things: (1) improperly indexing your case while sizing, which includes not using the proper shell holder, especially while using a normal expander ball on the sizing die (it also can stretch the brass). (2) The head of a turret press can flex; and (3) improper or sloppy bullet seating. This is also relevant when it comes to using a progressive press when trying to load accuracy ammo.

Mid Tompkins came up with a simple solution for better bullet seating years ago. Seat your bullet half way into the case, back off the seater die and rotate the case 180 degrees before you finish seating the bullet. It cuts down on run-out problems, especially with military brass. You also want to gently ream the inside of the neck mouth to keep from having any brass mar the surface of the bullet jacket and make proper seating easier. A tilted bullet often means a flyer.

*Actually some folks would say that if we are talking about things being off-center or out-of-round, we are actually talking about “eccentricity”. But the tools we use are called “Concentricity Gauges” and Concentricity is the term most commonly used when discussing this subject.

Tips for Enhancing ChargeMaster Performance & Precision

RCBS Chargemaster Powder dispenser tuning software plastic straw

Do you own an RCBS electronic powder dispenser? If you do, take the time to watch this ChargeMaster Tuning video from 8541 Tactical. This nine-minute video demonstrates how to re-program your ChargeMaster to “tune” the dispensing process. The video shows the exact programming procedures to follow, step-by-step. Some folks want a faster powder flow — others tune their machines for a more reliable drop (with fewer over-runs). One cheap and popular modification is to insert a 1″-long section of a McDonald’s plastic straw in the ChargeMaster’s silver dispensing tube. This works surprisingly well to smooth kernel drop and prevent “clumping” that can cause an over-charge. The McDonald’s straw MOD is demonstrated in this video, starting at the 6:22 mark.

Large-Diameter Dispensing Tube Mod
Many folks have had success with the McDonald’s straw modification demonstrated in the above video. However, some folks would like to get even better flow performance (with virtually no clumping). Forum Member Frank B. has come up with a new option using a brass hose fitting with a large outside diameter. The hose fitting (with tape wrapped around the barbed nose section) is placed inside the RCBS dispensing tube (have some kind of wrap — you don’t want metal-on-metal). Here’s how the unit looks installed:

Frank tells us: “I have found a cure for the over-throw problem. It is a simple 1/4″ barbed hose nipple. I wrapped a couple layers of tape around the barbed end for a snug fit. With this in place, I have thrown 100+ charges of Varget without a single overthrow. The ID of the barbed end needs to be approximately 3/16″ to feed a steady flow. This works because of the larger ID at the drop.”

Frank adds: “You can see in the photo that the powder is not stacking up. You can watch it drop one grain at a time. Hope this will take the aggravation out of your case charging.” For best performance with this brass fitting MOD, we recommend de-burring and smoothing out the front edge of the brass fitting over which the kernels drop.

How Travel Humidity Changes Can Affect Ammo Performance

powder bullet velocity humidity test bryan litz applied ballistics

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

accurateshooter USAMU Handloading hump day case lube lubrication spray can cartridge brass reloading marksmanship

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.”.

This photo shows a case lubrication rack made by a USAMU staffer.

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.

Reduce Run-Out — Try Rotating Your Cases During Bullet Seating

Bullet Seating Reloading rotate cartridge Run-out TIR

Here is a simple technique that can potentially help you load straighter ammo, with less run-out (as measured on the bullet). This procedure costs nothing and adds only a few seconds to the time needed to load a cartridge. Next time you’re loading ammo with a threaded (screw-in) seating die, try seating the bullet in two stages. Run the cartridge up in the seating die just enough to seat the bullet half way. Then lower the cartridge and rotate it 180° in the shell-holder. Now raise the cartridge up into the die again and finish seating the bullet.

Steve, aka “Short Range”, one of our Forum members, recently inquired about run-out apparently caused by his bullet-seating process. Steve’s 30BR cases were coming out of his neck-sizer with good concentricity, but the run-out nearly doubled after he seated the bullets. At the suggestion of other Forum members, Steve tried the process of rotating his cartridge while seating his bullet. Steve then measured run-out on his loaded rounds. To his surprise there was a noticeable reduction in run-out on the cases which had been rotated during seating. Steve explains: “For the rounds that I loaded yesterday, I seated the bullet half-way, and turned the round 180 degrees, and finished seating the bullet. That reduced the bullet runout by almost half on most rounds compared to the measurements from the first test.”

READ Bullet Seating Forum Thread »

Steve recorded run-out measurements on his 30 BR brass using both the conventional (one-pass) seating procedure, as well as the two-stage (with 180° rotation) method. Steve’s measurements are collected in the two charts above. As you can see, the run-out was less for the rounds which were rotated during seating. Note, the change is pretty small (less than .001″ on average), but every little bit helps in the accuracy game. If you use a threaded (screw-in) seating die, you might try this two-stage bullet-seating method. Rotating your case in the middle of the seating process won’t cost you a penny, and it just might produce straighter ammo (nothing is guaranteed). If you do NOT see any improvement on the target, you can always go back to seating your bullets in one pass. READ Forum Thread.
