Mount Press ABOVE Your Bench with Bench Topper

When Berry’s Bench Topper was first released a couple years ago, it proved very popular with hand-loaders looking for extra space on their bench. This unique all-metal riser lets you place a reloading press above your bench surface, clearing valuable space. Unfortunately, after the initial run of Bench Toppers sold out, this product have been nearly impossible to find. But now the Bench Topper is back…

We’re pleased to report that the Bench Topper is back in production. The Bench Topper, from Berry’s Manufacturing, is a sturdy platform that holds a loading press and storage bins in a raised position above your bench — effectively creating additional room for scales, trimmers, and component storage below. The $111.30 Bench Topper (Midsouth item 037-00191) can bolted to your bench, or it can be secured with C-Clamps (for easy removal). Do you load at the range? The Bench Topper can be easily transported in your vehicle, providing a handy platform for your press and powder measure.

Berry's Bench Topper Reloading Platform

Berry’s Bench Topper is crafted from CNC-machined aluminum and powder-coated silver for durability. It comes with two aluminum hangers for storage bins for bullets or brass. All fasteners are recessed for a clean work surface. NOTE: The Bench Topper must be assembled by the purchaser, and YOU MUST DRILL YOUR OWN HOLES for installation of your press or other hardware. This requires a few minutes of initial set-up time, but this allows a secure, custom installation for any brand of reloading press. CLICK HERE for Bench Topper Assembly Instructions (PDF file).

Bench Topper Specs:

Tech Tip: Shoulder Bump — How Much Is Enough?

Some of our readers have questioned how to set up their body dies or full-length sizing dies. Specifically, AFTER sizing, they wonder how much resistance they should feel when closing their bolt.

Forum member Preacher explains:

“A little resistance is a good, when it’s time for a big hammer it’s bad…. Keep your full-length die set up to just bump the shoulder back when they get a little too tight going into the chamber, and you’ll be good to go.”

To quantify what Preacher says, for starters, we suggest setting your body die, or full-length sizing die, to have .0015″ of “bump”. NOTE: This assumes that your die is a good match to your chamber. If your sizing or body die is too big at the base you could push the shoulder back .003″ and still have “sticky case” syndrome. Also, the .0015″ spec is for bolt guns. For AR15s you need to bump the shoulder of your cases .003″ – .005″, for enhanced reliability. For those who have never worked with a body die, bump die, or Full-length sizing die, to increase bump, you loosen lock-ring and screw the die in further (move die down relative to shell-holder). A small amount (just a few degrees) of die rotation can make a difference. To reduce bump you screw the die out (move die up). Re-set lock-ring to match changes in die up/down position.

That .0015″ is a good starting point, but some shooters prefer to refine this by feel. Forum member Chuckhunter notes: “To get a better feel, remove the firing pin from your bolt. This will give you the actual feel of the case without the resistance of the firing pin spring. I always do this when setting up my FL dies by feel. I lock the die in when there is just the very slightest resistance on the bolt and I mean very slight.” Chino69 concurs: “Remove the firing pin to get the proper feel. With no brass in the chamber, the bolt handle should drop down into its recess from the full-open position. Now insert a piece of fire-formed brass with the primer removed. The bolt handle should go to the mid-closed position, requiring an assist to cam home. Do this several times to familiarize yourself with the feel. This is how you want your dies to size your brass, to achieve minimal headspace and a nearly glove-like fit in your chamber.”

We caution that, no matter how well you have developed a “feel” for bolt-closing resistance, once you’ve worked out your die setting, you should always measure the actual amount of shoulder bump to ensure that you are not pushing the shoulder too far back. This is an important safety check. You can measure this using a comparator that attaches to your caliper jaws, or alternatively, use a sized pistol case with the primer removed. See Poor Man’s Headspace Gauge.

Top 10 Reloading Fails — Do You Agree?

Shooting Times has released an article entitled “Ten Most Common Reloading Mistakes”. Listed below are the Top Ten mistakes hand-loaders can make, at least according to Shooting Times. What do you think of this list — does it overlook some important items?

Shooting Times Reloading Failures Mistakes Top Ten 10

Top Ten Reloading Mistakes According to Shooting Times:
1. Cracked Cases — Reloaders need to inspect brass and cull cases with cracks.

2. Dented Cases — Dents or divets can be caused by excess case lube.

3. Excessive Powder Charge — Overcharges (even with the correct powder) can be very dangerous.

4. Primers Not Seated Deep Enough — “High” primers can cause functioning issues.

5. Crushed Primers — Some priming devices can deform primers when seating.

6. Excess Brass Length — Over time, cases stretch. Cases need to be trimmed and sized.

7. Bullets Seated Too Far Out — If the bullet is seated too long you may not even be able to chamber the round. Also, with hunting rounds, bullets should not engage the rifling.

8. Burrs on Case Mouths — Ragged edges on case mouths can actually shave bullet jackets.

9. Excess Crimp — This is a common problem with pistol rounds loaded on progressives. If case lengths are not uniform some cases will get too much crimp, others too little.

10. Inadequate Crimp — This can be an issue with magnum pistol cartridges in revolvers.

Do you agree with this list? We think some important things are missing, such as not adjusting full-length sizing dies properly. This can cause the shoulder to be pushed back too far (or not far enough). Another common mistake is using brass that is worn out, i.e. stretched in the case-head area from multiple cycles of hot loads. We also think the #1 error a reloader can make is using the wrong powder altogether. That can be a fatal mistake. See what happens when you load pistol powder in a rifle.

For Novice Reloaders, the Winner Is…

What’s the best book for folks getting started in metallic cartridge reloading? According to our Forum members, the best manual for “newbie” reloaders is the Lyman Reloading Handbook. In our Shooters’ Forum, a newcomer to reloading was looking for a basic reloading guide that also included load data. The most recommended book was the Lyman Handbook, now in its 49th Edition. Along with “how-to” advice on reloading procedures, the Lyman Manual features cartridge specifications and load data for the most popular cartridges.*

Lyman 49th Reloading Manual

Here are some comments from Forum members:

“The Lyman book is an excellent manual with a large section describing the process of reloading. I heartily recommend it. As a beginning reloader, you may want to consider purchasing more than one book in order to get different perspectives on the reloading regimen. One can never be too careful. A ‘minor’ mistake can be costly.” — Cort

“In my opinion, the Lyman Manual is one of the best for the beginning reloader since it covers all the basics and some advanced methods. If possible, you would be also well served to hook up with an experienced reloader, preferably a target shooter or long-range varmint hunter, who can also give you some very useful pointers on precision reloading.” – K22

Editor’s NOTE: K22 echoes the advice we give to new hand-loaders. We suggest that novices find an experienced mentor who can “show them the ropes” and guide them through the basics.

Another gun blogger agrees that the Lyman Manual is a logical choice for new handloaders:

Carteach Review: The Lyman Reloading Manual
“[Lyman publishes] an excellent manual for any handloader, but especially for those new to the craft. Perhaps the best judgment of a handloader’s regard for a reloading manual is which one he chooses to give someone new to the fold. The needs of a new reloader differ from those of someone with long experience, and the right manual can set the foundation for years of safe procedures. Here is the one I choose to give a good friend embarking down the path:”

Lyman 49th Reloading Manual

Carteach adds: “Lyman has always taken pains to provide very clear and understandable instruction on the basic process of reloading cartridges. The imaging is helpful and to the point. The load data Lyman provides is comprehensive, and [Lyman] takes the time to note special circumstances which new loaders need to be aware of. As example, the .30-06 section has some words regarding the M-1 Garand and its special needs. For someone who has never loaded for the Garand, these few sentences are golden!”

More Good Reference Books for Reloaders
Other book suggestions include The ABCs of Reloading, Glen Zediker’s Handloading for Competition, and The Book of Rifle Accuracy by Tony Boyer. The Boyer book is more for advanced handloaders, though it contains advice that can help beginners too. Forum member VTMarmot writes: “I wish I had read Tony Boyer’s book before I ever started handloading. The concept of using a bushing neck die that also sizes the body is the simplest, most accurate way to get accurate handloads and long brass life. This is true whether or not you turn necks, and whether you are loading for competition or hunting.”

*We recommend that you always double-check printed load data with the latest web-based data from the actual powder manufacturers. Powder properties can change. The most current powder data is usually found on the powder-makers’ websites.

Reloading 101: Seven Fundamental Safety Guidelines

seven reloading safety tips powder primers brownells manual

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. This includes keeping 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.

Reloading, a Lifetime Hobby (Memories of My Father)

Sierra Bullets Ballistic Technician Gary Prisendorf has written a nice essay about how reloading can become a life-time hobby, a rewarding pastime that can bring together a father and son…

by Gary Prisendorf
For as long as I can remember I have been around reloading. I have tons of childhood memories of my father reloading and shooting. I remember how he would let me help him load his ammunition, by letting me clean primer pockets or wipe the sizing lube off of his cases. I really thought I was doing something. Well, I guess I was, I was spending quality time with my father doing something that would become a great hobby and eventually land me a great job working for Sierra Bullets.

Herters Press Sierra Bullets Reloading Prisendorf Father son

I remember watching my father sizing cases on his Herters press, dropping his powder charges with a Belding & Mull powder measure and weighing powder charges with his Texan scales. Heck, I can even remember when he would buy powder at a local pawn shop, and they would weigh it out and put it in a paper sack. He would save his empty powder cans, wrap them with masking tape and write what the powder was on them with a black magic marker.

Herters Press Sierra Bullets Reloading Prisendorf Father son

When I was in Junior High, I got my first shotgun, a 20 gauge Mossberg 500 and within a couple of weeks my father came home with a 20 gauge Lee Load-All and a pound of Blue Dot. He gave me a crash course on how to use it, and got me up and running with a couple of safe loads. I put a lot of shells through that old 20 gauge.

From that day forward I was hooked. If I got a new gun, I was loading ammunition for it. I don’t buy factory ammunition unless I just want to shoot it up so I can get some once fired brass. I reload everything that I shoot, except for rimfire stuff, and if I could figure out how to do that safely, I would probably load that too.

Through the years I have learned to appreciate things — such as once-fired military .30-06 cases that can be converted to obscure cartridge types. And I know the value of a five-gallon bucket of lead wheel weights that will be melted down and cast into bullets.

I remember finding 19 once-fired Norma 7.7×58 Arisaka cases laying on the ground at a public shooting range, and it was like Christmas came early. I must have looked for that 20th case for about thirty minutes, but I never did find it.

I can’t thank my father enough for getting me started in reloading, he gave me a great hobby, many wonderful memories and taught me the skills that gave me a career doing something that I love.

If you are a reloader, teach someone. You may just give them a hobby for the rest of their life and who knows, you could help them find an enjoyable career, doing something that they love. — Gary Prisendorf

What Happens When You Load Pistol Powder in a Rifle Cartridge

This is a grim tale. A man almost lost the use of his right hand, and did suffer terrible injuries to his fingers. All because he picked the wrong bottle of powder off the shelf.

Varget Kaboom TiteGroup Hand injury reloading fingers accident

Similar Labels, Disasterous Consequences
The shooter, Denny K., was assembling some rounds for his brand new 7mm-08 Savage hunting rifle. He thought he was loading with Hodgdon Varget. Instead he had filled his powder measure with Hodgdon TiteGroup, a fast-burning pistol powder. The labels are similar, so the mistake is understandable. But the results were devastating. Here’s what 41 grains of TiteGroup can do in a 7mm-08:

Varget Kaboom TiteGroup Hand injury reloading fingers accident

Posting on the Firing Line, in a thread entitled “Lucky to Be Alive”, Denny writes:

“This is the hardest post to post. I know if I had read it a week ago my comment would have been: ‘You have no business reloading’. I had everything perfect, except pouring the wrong powder in the powder measure. I type this slowly with my left hand, embarrassed but … possibly saving someone else a tragedy or, like me, a long drive to the Emergency Room and surgery to save my finger.”

CLICK HERE for bigger, more graphic photo of injury.
Varget Kaboom TiteGroup Hand injury reloading fingers accident

The Still-Sealed Bottle of Varget
Denny did not initially comprehend exactly why the kaboom happened. He thought maybe his new Savage rifle was at fault. Then, on his return home, he discovered something…

Denny wrote: “The seven-hour period it took to go to ER, transport to Trauma Center and surgery made me think it was a Savage rifle issue. Brand new rifle, new brass, triple-checked loading data. The next day I was humbled when I realized the Varget powder was still sealed.

I knew what powder to use. I thought [Varget] was what I used. Not until the following day did I realize the Varget was still sealed.”

At that point, Denny realized what caused the accident — “operator error”. He knew he had to warn others about using the wrong powder: “I knew I needed to share my mistake, even though it is embarrassing, just to remind people. I’ve been reloading for 30 years…”

Editor’s Comment: Denny was not a novice reloader. His experience demonstrates that this kind of mistake can be made by any hand-loader, even one with decades of experience. Be safe guys, take your time when you load your ammo. Remove powders from measures after your loading sessions (pistol powders can look very similar to rifle powders). And by all means CHECK the LABEL on the jug. As the TiteGroup label says: “A little goes a long way.”

It’s not a bad idea to separate your pistol powders from your rifle powders, or perhaps even load for pistol in a separate part of your workshop.

How to Remove a Cartridge Case Stuck in a Die

To err is human… Sooner or later you’ll probably get a case stuck in a die. This “fix-it” article, which originally appeared in the Western Powders Blog, explains the procedure for removing a firmly stuck cartridge case using an RCBS kit. This isn’t rocket science, but you do want to follow the directions carefully, step-by-step. Visit the Western Powders Blog for other helpful Tech Tips.

Curing the Stuck Case Blues

stuck72

decapstem72Sticking a case in the sizer die is a rite of passage for the beginning handloader. If you haven’t done it yet, that’s great, but it probably will eventually happen. When it does, fixing the problem requires a bit of ingenuity or a nice little kit like the one we got from RCBS.

The first step is to clear the de-capping pin from the flash hole. Just unscrew the de-capping assembly to move it as far as possible from the primer pocket and flash hole (photo at right). Don’t try to pull it all the way out. It won’t come. Just unscrew it and open as much space as possible inside the case.

Place the die upside down in the padded jaws of a vise and clamp it firmly into place. Using the supplied #7 bit, drill through the primer pocket. Be careful not to go too deeply inside the cartridge once the hole has opened up. It is important to be aware that the de-capping pin and expander ball are still in there and can be damaged by the bit.

Drill and Tap the Stuck Case
taping72drilling72

Once the cartridge head has been drilled, a ¼ – 20 is tap is used to cut threads into the pocket. Brass is relatively soft compared to a hardened tap, so no lube is needed for the tapping process. RCBS says that a drill can be used for this step, but it seems like a bit of overkill in a project of this nature. A wrench (photo above right) makes short work of the project.

RCBS supplies a part they call the “Stuck Case Remover Body” for the next step. If you are a do-it-yourselfer and have the bit and tap, this piece is easily replicated by a length of electrical conduit of the proper diameter and some washers. In either case, this tool provides a standoff for the screw that will do the actual pulling.

pulling72fingers72

With an Allen Wrench, Finish the Job
Run the screw through the standoff and into the tapped case head. With a wrench, tighten the screw which hopefully pulls the case free. Once the case is free, clamp the case in a vice and pull it free of the de-capping pin. There is tension here because the sizing ball is oversized to the neck dimension as part of the sizing process. It doesn’t take much force, but be aware there is still this last little hurdle to clear before you get back to loading. Don’t feel bad, everyone does this. Just use more lube next time!

Squeeze Play — The Many Factors Involved in Neck Tension

Redding neck bushingsIn our Shooters’ Forum a reader asked: “How much neck tension should I use?” This prompted a Forum discussion in which other Forum members recommended a specific number based on their experience, such as .001″, .002″, or .003″. These numbers, as commonly used, correspond to the difference between case-neck OD after sizing and the neck OD of a loaded round, with bullet in place. In other words, the numbers refer to the nominal amount of interference fit (after sizing).

While these commonly-used “tension numbers” (of .001″, .002″ etc.) can be useful as starting points, neck tension is actually a fairly complex subject. The actual amount of “grip” on the bullet is a function of many factors, of which neck-OD reduction during sizing is just one. Understanding these many factors will help you maintain consistent neck tension as your brass “evolves” over the course of multiple reloadings.

Neck Tension (i.e. Grip on Bullets) Is a Complex Phenomenon
While we certainly have considerable control over neck tension by using tighter or looser bushings (with smaller or bigger Inside Diameters), bushing size is only one factor at work. It’s important to understand the multiple factors that can increase or decrease the resistance to bullet release. Think in terms of overall brass-on-bullet “grip” instead of just bushing size.

One needs to understand that bushing size isn’t the beginning and end of neck tension questions, because, even if bushing size is held constant, the amount of bullet “grip” can change dramatically as the condition of your brass changes. Bullet “grip” can also change if you alter your seating depth significantly, and it can even change if you ultrasonically clean your cases.

Bullet grip is affected by many things, such as:

  • 1. Neck-wall thickness.
  • 2. Amount of bearing surface (shank) in the neck.
  • 3. Surface condition inside of neck (residual carbon can act as a lubricant; ultrasonic cleaning makes necks “grabby”).
  • 4. Length of neck (e.g. 6BR neck vs. 6BRX).
  • 5. Whether or not the bullets have an anti-friction coating.
  • 6. The springiness of the brass (which is related to degree of work-hardening; number of firings etc.)
  • 7. The bullet jacket material.
  • 8. The outside diameter of the bullet and whether it has a pressure ridge.
  • 9. The time duration between bullet seating and actual firing (necks can stiffen with time).
  • 10. How often the brass is annealed

— and there are others…

Seating Depth Changes Can Increase or Decrease Grip on Bullet
You can do this simple experiment. Seat a boat-tail bullet in your sized neck with .150″ of bearing surface (shank) in the neck. Now remove the bullet with an impact hammer. Next, take another identical bullet and seat it with .300″ of bearing surface in another sized case (same bushing size/same nominal tension). You’ll find the deeper-seated bullet is gripped much harder.

PPC lapua brassNeck-Wall Thickness is Important Too
I have also found that thinner necks, particularly the very thin necks used by many PPC shooters, require more sizing to give equivalent “grip”. Again, do your own experiment. Seat a bullet in a case turned to .008″ neckwall thickness and sized down .003″. Now compare that to a case with .014″ neckwall thickness and sized down .0015″. You may find that the bullet in the thin necks actually pulls out easier, though it supposedly has more “neck tension”, if one were to consider bushing size alone.

In practical terms, because thick necks are less elastic than very thin necks, when you turn necks you may need to run tighter bushings to maintain the same amount of actual grip on the bullets (as compared to no-turn brass). Consequently, I suspect the guys using .0015″ “tension” on no-turn brass may be a lot closer to the guys using .003″ “tension” on turned necks than either group may realize.

Toward a Better Definition of Neck Tension
As a convenient short-cut, we tend to describe neck tension by bushing size alone. When a guy says, “I run .002 neck tension”, that normally means he is using a die/bushing that sizes the necks .002″ smaller than a loaded round. Well we know something about his post-sizing neck OD, but do we really have a reliable idea about how much force is required to release his bullets? Maybe not… This use of the term “neck tension” when we are really only describing the amount of neck diameter reduction with a die/bushing is really kind of incomplete.

My point here is that it is overly simplistic to ask, “should I load with .001 tension or .003?” In reality, an .001″ reduction (after springback) on a thick neck might provide MORE “grip” on a deep-seated bullet than an .003″ reduction on a very thin-walled neck holding a bullet with minimal bearing surface in the neck. Bushing ID is something we can easily measure and verify. We use bushing size as a descriptor of neck tension because it is convenient and because the other important factors are hard to quantify. But those factors shouldn’t be ignored if you want to maintain consistent neck tension for optimal accuracy.

Consistency and accuracy — that’s really what this all about isn’t it? We want to find the best neck tension for accuracy, and then maintain that amount of grip-on-bullet over time. To do that you need to look not only at your bushing size, but also at how your brass has changed (work-hardened) with time, and whether other variables (such as the amount of carbon in the neck) have changed. Ultimately, optimal neck tension must be ascertained experimentally. You have to go out and test empirically to see what works, in YOUR rifle, with YOUR bullets and YOUR brass. And you may have to change the nominal tension setting (i.e. bushing size) as your brass work-hardens or IF YOU CHANGE SEATING DEPTHS.

Remember that bushing size alone does not tell us all we need to know about the neck’s true “holding power” on a bullet, or the energy required for bullet release. True bullet grip is a more complicated phenomenon, one that is affected by numerous factors, some of which are very hard to quantify.

Tips for Loading Straighter Ammo with Less Run-Out

This article originally appeared in Sinclair Intl’s Reloading Press Blog, which has been merged into the Gun Tech Section on Sinclair’s website, www.SinclairIntl.com

Steps to Minimize Bullet Run-Out

Poor bullet run-out can cause poor and inconsistent accuracy, and variations in bullet velocities. The truer the loaded round, the more consistent your results will be on paper and across the chronograph.

Sinclair Concentricity gaugeMeasuring Concentricity
We all know that low run-out is the goal. But how can you tell if your run-out is high or low? Run-out is generally measured in thousandths of an inch with a concentricity gauge. There are many concentricity gauges to choose from that work well. Some work on loaded rounds only, some have a bullet straightening feature, and a few work on both loaded rounds and empty cases for checking case neck concentricity. The tool of choice for the Sinclair Reloading Tech Staff is the Sinclair Concentricity Gauge (Part # 09-175).

This tool is a mainstay on my bench, and it is used about as much as I use my reloading press! The tool uses two sets of bearings that are set on lateral, length-adjustable anodized aluminum blocks to accommodate cartridges from .221 Fireball-sized cases up to .50 BMG. The indicator is set on a height adjustable swiveling base on a stand that can be used for checking bullet or case neck run-out. The adjustable blocks ride aligned in a precision-milled slot. The entire set up is on an anodized base plate that gives excellent support during the process that is crucial to operation and accuracy. Basically the operation consists of placing a loaded round (for checking bullet run-out) or an empty case (for case run-out) on the bearings with the indicator end touching the chosen point to be measured. The case is easily spun with one finger as the indicator measures the amount of run-out. Once this process has been done a few times it is a fast and accurate means of measurement. In terms of indicator type being used, whether dial or digital, I actually prefer a standard dial indicator over the digital type. My reason for this choice is that you can see the needle jump when run-out is present. I believe this to be easier and faster than looking at digital numbers while measuring. In the video below, Sinclair’s Bill Gravatt shows how to use the Sinclair Concentricity Gauge correctly.

Sizing Steps to Minimize Run-Out
One of the most common steps in the reloading process that contributes to bullet run-out occurs is the sizing operation. If improper techniques are used or there are issues with the sizing die set up, a once perfectly concentric case can become out of whack. By using the proper dies for your application, properly setting up the die/shell holder or floating the de-capping/expander assembly, you can eliminate problems before they happen.

Sinclair Concentricity gaugeMany of us on the technical staff choose the Redding Type-S series of dies. These are full-Length or neck sizing dies that utilize a removable/changeable neck bushing (sold separately) to size the neck according to your application. These dies are machined with true precision and quality in mind. The Type-S dies come with a standard de-capping assembly with a caliber-specific expander ball in place. In addition to this an undersized retainer to hold the de-capping pin is included with the die. In my experience with these dies I use the standard expander ball with new, unfired brass on the initial re-size. I will then use the undersized retainer in place of the expander ball with brass that has been fired. I have found this step crucial in my reloading regiment to minimize bullet run out. The use of the expander ball can cause a few thousandths of run-out when the case is being pulled back out of the sizing die. With the undersized retainer in place the only thing that touches the neck of the case in sizing is the bushing. If you prefer to use an expander ball, Redding offers caliber specific carbide floating expander balls that fit on the de-capping rod. This free floating expander ball will self center on the case neck, and reduce the amount of run-out that can be caused by a standard expander ball.

When setting up a Type-S sizing die, set the neck bushing into the die with the numbers facing down toward the body of the die. Tighten the de-capping assembly until it contacts the bushing and then back it off ¼ of a turn. This allows the bushing to free float in the die. You should be able to hear the bushing rattle if you shake the die. Having the bushing free floating self centers the neck, and again minimizes any run-out that can occur.

If you prefer other brands of sizing dies there are a few tricks that people use to minimize run-out as well. Many reloaders claim that the use of an O-ring at the base of the de-capping assembly lock nut will float the assembly and help self center during sizing. Another trick that has been used is to remove the retaining pin on the shell holder slot on the press ram, and use an O-ring in its place to hold the shell holder in place. This allows the shell holder to self center during sizing as well.

Seating Steps to Minimize Run-Out
Run-out issues can arise during the bullet seating process. To reduce run-out during seating, use a high-quality die with a sliding sleeve. The sliding sleeve perfectly aligns the case with the bullet to be seated. Good examples of these dies are the Redding Competition Micrometer bullet seating dies, Forster Ultra Seaters, or RCBS Competition Seating dies. All of these dies utilize a micrometer top to precisely set seating depth. They are all very high quality dies that have tight tolerances to maximize bullet straightness during seating.

We receive many questions about seating long pointed bullets such as the Berger VLD or Hornady A-Max. One problem that the reloader faces with longer bullets is that they are so long that the standard seating stem is not machined deep enough to contact these bullets properly. The point of the bullet “bottoms out” in the stem and the result is off-center seating and/or rings and dents on the bullet nose. If you plan on using such bullets, you should purchase a “VLD” style seating stem, which is cut to accommodate the longer bullets. The use of this stem results in truer seating of the bullet without leaving a ring or marring the tip of the bullet.

Besides using a traditional press and threaded seating die, another great way to get a true bullet seat is by using an arbor press and Wilson chamber-type seating die. These dies are cut to very tight tolerances and have proven themselves as the main choice for bench rest enthusiasts. The design of the die positively aligns the case with the bullet as they are both captured by the die before the bullet is pushed straight into the case by the stem. These seating dies are available with the standard seating cap and stem or an additional micrometer top can be added for precise adjustment. Wilson also offers a stainless seating die with an integral micrometer seating head.

Finally another trick used by many in the seating process is to turn the case while the bullet is being seated. Some people claim this will keep things straight. What they do is raise the ram in increments while seating and rotate the case in the shellholder in increments of 90 degrees from the original starting while the bullet is being seated. Personally I have tried this and have seen no significant difference at all. However you may be the judge of this one. It makes sense, and maybe I should try this a little more before I rule it out.

After the Rounds Are Loaded — Batch Sorting by Concentricity Levels
No matter how meticulous you are, and no matter how good your components and tools are, run-out will still show up. Reloaders can drive themselves crazy trying to make each and every loaded round a true “0” in run-out. You will still see some minimal amount no matter what you do. Set yourself a standard of maximum allowable run-out for your loads. For instance for my Long Range 600- and 1000-yard F-Class loads I like to see .002” or less. I average .0015” and see a few in the range up to .004”. I spin each loaded round on my Sinclair Concentricity Gauge and sort them by run-out. Those that run over .002” I use for sighters or practice. Though achieving zero run-out (on every round) isn’t possible, minimizing run-out can definitely help your performance. Not only will your loads shoot better but you will have one less thing to worry about when you are lining up the sights on the target.

Shoot BR Cases from Your PPC Action with Rebated Rims

Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.

To convert a PPC-boltface action to shoot the bigger cases you can spend a ton of money and buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.” Below are photos of a rebated 6BR case, along with the lathe form tool Butch uses to rebate the case rims.
