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.”
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..
Lyman’s popular Case Length Gauge is now bigger and better. The enhanced version II of Lyman’s Case Length Gauge is much larger than the original version. The E-Zee Case Gauge II now measures more than 70 cartridge types — way more than before. This tool is a metal template with SAAMI-max-length slots for various cartridge types, including relatively new cartridges such as the .204 Ruger and Winchester Short Magnums. This tool allows you to quickly sort brass or check the dimensions. If you have a bucketful of mixed pistol brass this can save you hours of tedious work with calipers. You can also quickly check case lengths to see if it’s time to trim your fired brass.
If you load a wide variety of calibers, or do a lot of pistol shooting, we think you should pick up one of these Lyman Case Gauge templates. They are available for under $26.00 at Brownells ($24.99) and Amazon.com ($19.39). The E-Zee Case Gauge has long been a popular item for hand-loaders.
NOTE: For years the E-Zee Case Gauge had a silver finish with black lettering, as shown in the video. Some of the most recent production of E-Zee Case Gauges have a new “high contrast” look, with white lettering on a black frame. You may get either Case Gauge version when you order online (Brownells shows silver, Amazon shows black). We actually prefer the older, silver version.
Case Gauge Should Last a Lifetime
Easily measure the case length of over 70 popular rifle and pistol cases with Lyman’s new E-Zee Case Length Gauge II. This really is a “must-have” piece of kit for any gun owner who hand-loads numerous pistol and rifle calibers.
This rugged, precisely-made metal gauge makes sorting or identifying cases fast and accurate. The template is machined with SAAMI max recommended case lengths. Made from metal, with no moving parts, the E-Zee Case Gauge II should last a lifetime.

This article originally appeared on the USAMU Facebook Page. The USAMU regularly published reloading advice for many years. Check the Facebook archives for related USAMU articles.
Here at the U.S. Army Marksmanship Unit (USAMU), we receive inquiries from shooters at many skill levels. One of the most frequent questions we are asked is, “What equipment do you recommend I buy to start handloading?”
Often, the handloader will be focused on producing ammo in quantity, and a big concern is whether to begin with a single-stage vs. a progressive press. However, there is one critical item that often gets overlooked as folks talk about the especially interesting topics such as reloading die brands and types, scale types and brands. And, what might that item be?
“When all else fails, read the what?” Yes, we recommend those new to handloading actually begin with reading the early chapters of one or, preferably two quality handloading manuals. They contain copious information on basic handloading safety, how to choose and use components, and how to recognize and avoid potentially dangerous conditions. Of course, they also do a fine job of teaching new loaders the correct methods of adjusting dies, determining safe loads and improving accuracy. Beginners can recognize and avoid many potential pitfalls, shortening the learning curve tremendously.
As a government entity, we aren’t able to make specific brand-name recommendations as such. However, recent manuals from the major bullet and powder manufacturers, especially those who emphasize accuracy and match-type bullets are generally a wise choice.
Handloaders often come to prefer one or two maker’s manuals over others for various reasons. Asking a friend who’s already an experienced loader which manuals they recommend is a good start. Borrowing one or more to read before purchasing is another.
This is a good way to both save money and get a feel for the variety of component types and data that are available. Comparing differences in data from different manuals in the same caliber, with the same powder and bullet weight can be an eye-opener. It is also a wise step in researching any loading project before one begins—and the reasons for the differences are fully explained in the manuals!
The AMU recommends buying proven, high-quality equipment. It should have a reputation for great durability, good ergonomics and reasonable-to-excellent precision. In addition, ask fellow shooters which companies have a good reputation for support after the sale. Several of the better handloading companies set the bar very high.

With the better ones, it’s common to call to order small replacement parts and receive them at no charge in the mail immediately thereafter. Other companies don’t enjoy such a sterling reputation. Often, these focus on cheap equipment made with low-quality materials, aimed at those to whom cost is the prime consideration.
Good quality equipment not only leads to less frustration, faster production, better results and less misery — it is also an excellent investment. Certain companies’ products sell virtually instantly on the used market and retain high resale value. Other gear from less well-regarded companies is much more difficult to sell. Moreover, it brings far less of its original purchase price—if it can be sold at all.
Ask veteran handloaders — preferably those who are still very active in the shooting sports — which equipment they prefer, and why. After getting specific recommendations, search for reviews of that equipment, as well as possible alternates and newer designs. Learn the steps of operating the various options, and evaluate them for efficiency, effort and precision. A little research can pay big dividends here!
Photo 1: Three Near-Equal-Weight 7mm Bullets with Different Shapes
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284″) very near the cannelure. This taper is often seen on similar bullets — it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430”, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!
This article from the USAMU covers an important safety issue — why you should never assume that a “book” load for a particular bullet will be safe with an equal-weight bullet of different shape/design. The shape and bearing surface of the bullet will affect the pressure generated inside the barrel. This is part of the USAMU’s Handloading Hump Day series, published on the USAMU Facebook page.
Beginning Handloading, Part 13:
Extrapolating Beyond Your Data, or … “I Don’t Know, What I Don’t Know!”
We continue our Handloading Safety theme, focusing on not inadvertently exceeding the boundaries of known, safe data. Bullet manufacturers’ loading manuals often display three, four, or more similar-weight bullets grouped together with one set of load recipes. The manufacturer has tested these bullets and developed safe data for that group. However, seeing data in this format can tempt loaders — especially new ones — to think that ALL bullets of a given weight and caliber can interchangeably use the same load data. Actually, not so much.
The researchers ensure their data is safe with the bullet yielding the highest pressure. Thus, all others in that group should produce equal or less pressure, and they are safe using this data.
However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. These can occasionally range up to 0.001″ by design. Thus, choosing untested bullets of the same weight and caliber, and using them with data not developed for them can yield excess pressures.
This is only one of the countless reasons not to begin at or very near the highest pressure loads during load development. Always begin at the starting load and look for pressure signs as one increases powder charges.
Bullet bearing surface length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In photo 1 (at top), note the differences in the bullets’ appearance. All three are 7mm, and their maximum weight difference is just five grains. Yet, the traditional round nose, flat base design on the left appears to have much more BSL than the sleeker match bullets. All things being equal, based on appearance, the RN/FB bullet seems likely to reach maximum pressure with significantly less powder than the other two designs.
Bearing Surface Measurement Considerations
Some might be tempted to use a bullet ogive comparator (or two) to measure bullets’ true BSL for comparison’s sake. Unfortunately, comparators don’t typically measure maximum bullet diameter and this approach can be deceiving.
Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
In Photo 2, two 7mm comparators have been installed on a dial caliper in an attempt to measure BSL. Using this approach, the BSLs differed sharply from the original [measurements]. The comparator-measured Bullet 1 BSL was 0.694” vs. 0.324” (original), Bullet 2 was 0.601” (comparator) vs. 0.430” (original), and Bullet 3 (shown in Photo 2) was 0.602” (comparator) vs. 0.463” (original). [Editor’s comment — Note the very large difference for Bullet 1, masking the fact that the true full diameter on this bullet starts very far back.]
Lyman makes a very handy product for reloaders that can save space on your reloading bench and give you more efficient powder flow into your cases. With common plastic “one size fits all” type powder funnels, the powder sometimes sticks to the sides of the funnel. Or, the fit to the case mouth is less than ideal so some of the kernels end up on the bench.
Precision powder funnels solve those problems. But what if you shoot a wide range of calibers with big and small case mouths? Lyman has the answer: the Brass-Smith Precision Funnel set, now $28.99 on Amazon. This handy product combines a static-free cast aluminum funnel with a set of SIX (6) CNC-machined inserts that fit cartridges from .22 caliber all the way up to .338 caliber. It is easy to swap the inserts to match the particular cartridge you are loading. In this Ultimate Reloader video, our friend Gavin Gear shows how to use the Lyman Precision Powder Funnel Set with multiple neck-diameter inserts:
Product Description: “The Brass-Smith Precision Funnel set is made to be completely static-free, no more powder clinging to surfaces which can happen with lightweight plastic Funnel. This is no ‘one size fits all’ funnel — the Brass Smith Precision Funnel set uses precision-machined, caliber-specific inserts to properly fit the case neck. CNC-turned aluminum inserts to fit specific cartridge families for calibers 22 to 338. Inserts are laser-marked for caliber identification. The inserts can be quickly and easily installed by simply pushing them into place and then pulling them out when changing calibers. The Funnel comes with inserts for .22, .243/6mm, .25/6.5mm, .270/7mm, .30 and .338 caliber rifle cartridges. A padded storage case neatly stores the funnel and inserts when not in use.”
Forum Member Likes the Lyman Precision Powder Funnel Set
One of our Accurate Shooter Forum members, Garandman, purchased the Lyman Precision Funnel System. He has used it now for multiple cartridge types and is very pleased with the results. Here is his report:
“I wanted to share my good experience with the Lyman powder funnel. First off, with the funnels being aluminum / pot metal, no static charge forms and the powder kernels go right down the funnel into the case with no hang-up.
Also the funnel comes with interchangeable case neck dimension inserts so you get no powder loss outside the case neck. And the funnel is also is less likely to stick to the case neck and pull it out of your loading block. That could spill powder all over the place.”
Overall, the Lyman Precison Funnel Set with case neck inserts has done a great job for Garandman and he suggests you may want to add this tool to your reloading tool collection. Below is a Lyman Precision Funnel Set review from Johnny’s Reloading Bench. This video review has nice close-ups of the six precision inserts from .22 to .338 calibers.
You can never be too safe when hand-loading your own ammunition. This helpful Brownells video outlines the Seven Fundamental Reloading Safety Tips. This is important information for novice hand-loaders and a good refresher for those with reloading experience!
Summary of the Seven Safety Tips:
1. Store your reloading supplies in a safe and dry location, away from children and away from any possible source of ignition. It is also smart to keep your powder and primers separate.
2. Get and use respected reloading manuals, especially for new cartridges. Start low and work up slowly while watching for warning signs of pressure and/or case fatigue.
3. Locate your reloading activity where you will not be distracted. If you get interrupted, stop. (Distractions will eventually lead to mistakes.)
4. Do NOT mix powders. Keep your powders clearly marked and dated. You can use masking tape to write the date on the container.
5. If you load the same cartridge type for different firearms, make sure your ammo headspaces properly in each gun.
6. Check cases frequently. Look for split necks, case head separation or other signs of fatigue and excessive pressure.
7. If reloading military brass, be aware that case capacity is usually reduced, and initial loads should be at least 10-15% lower than published data.
Here are some other tips that will help your avoid making costly mistakes (such as using the wrong powder, or undercharging a case):
Powder Type — Always double-check the label on your powder containers. After placing powder in the powder measure, put a piece of tape on the measure with the powder type written on it. Some guys write the powder type on a card and place that right in the hopper.
Scale Drift — Electronic balances can drift. If you are using a digital powder scale, calibrate the scale with a test weight every 50 rounds or so.
Case Fill — If you throw more than one charge at a time, look INSIDE every case before seating a bullet. Squib charges can be dangerous if you don’t notice them before firing the next round.
Progressive Presses — When using a progressive press, consider using an RCBS Lock-Out Die. This will detect a low charge and stop the machine. These dies will work with RCBS, Hornady, and Dillon progressives.
There is an excellent article about primers on the Shooting Times website. We strongly recommend you read Mysteries And Misconceptions Of The All-Important Primer, written by Allan Jones. Mr. Jones is a bona fide expert — he served as the manager of technical publications for CCI Ammunition and Speer Bullets and Jones authored three editions of the Speer Reloading Manual.
This authoritative Shooting Times article explains the fine points of primer design and construction. Jones also reveals some little-known facts about primers and he corrects common misconceptions. Here are some highlights from the article:
Size Matters
Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.
Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.
Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.
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 $64.52. Or you can buy just the Hand Press by itself for $49.91 at Amazon. That’s a great deal.
Lee 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 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.”
He who dies with the most toys wins — right? Well Sinclair has another interesting gadget you can add to your reloading bench. The Sinclair Case Neck Sorting Tool lets you quickly sort brass by neck-wall thickness. For those who shoot “no-turn” brass, this can improve neck-tension consistency. Large variances in neck-wall thickness can cause inconsistent neck “grip” on the bullet. Generally, we’ve found that more consistent neck tension will lower ES and (usually) improve accuracy. We know some guys who shoot no-turn 6mmBR brass in competition with considerable success — but their secret is pre-sorting their brass by neck-wall thickness. Cases that are out-of-spec are set aside for sighters (or are later skim-turned).

How the Case Neck Sorting Tool Works
Here’s how the Sinclair tool works. Cases are rotated under an indicator tip while they are supported on a case-neck pilot and a support pin through the flash hole. The unit has a nice, wide base and low profile so it is stable in use. The tool works for .22 through .45 caliber cases and can be used on .17- and .20-caliber cases with the optional carbide alignment rod. The MIC-4 pin fits both .060 (PPC size) and .080 (standard size) flash holes. Sinclair’s Case Neck Sorting Tool can be ordered with or without a dial indicator. The basic unit without dial indicator (item 749-006-612WB) is priced at $59.99. You can also buy the tool complete with dial indicator (item 749-007-129WB) for $89.99. IMPORTANT: This sorting tool requires caliber-specific Case Neck Pilots which must be ordered separately.
Editor’s Comment: The purpose of this Sinclair tool is rapid, high-quantity sorting of cartridge brass to ascertain significant case-neck-wall thickness variations. Consider this a rapid culling/sorting tool. If you are turning your necks, you will still need a quality ball micrometer tool to measure neck-wall thickness (to .0005) before and after neck-turning operations.
