Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. This past week’s “Handloading Hump Day” article, the latest in a 7-part series, relates to chronograph testing and statistical samples. We highly recommend you read this article, which offers some important tips that can benefit any hand-loader. Visit the USAMU Facebook page next Wednesday for the next installment.
Chronograph Testing — Set-Up, Sample Sizes, and Velocity Factors
Initial Chronograph Setup
A chronograph is an instrument designed to measure bullet velocity. Typically, the bullet casts a shadow as it passes over two electronic sensors placed a given distance apart. The first screen is the “start” screen, and it triggers an internal, high-speed counter. As the bullet passes the second, or “stop” screen, the counter is stopped. Then, appropriate math of time vs. distance traveled reveals the bullet’s velocity. Most home chronographs use either 2- or 4-foot spacing between sensors. Longer spacing can add some accuracy to the system, but with high-quality chronographs, 4-foot spacing is certainly adequate.
Laboratory chronographs usually have six feet or more between sensors. Depending upon the make and model of ones chronograph, it should come with instructions on how far the “start” screen should be placed from one’s muzzle. Other details include adequate light (indoors or outdoors), light diffusers over the sensors as needed, and protecting the start screen from blast and debris such as shotgun wads, etc. When assembling a sky-screen system, the spacing between sensors must be extremely accurate to allow correct velocity readings.
Statistics: Group Sizes, Distances and Sample Sizes
How many groups should we fire, and how many shots per group? These questions are matters of judgment, to a degree. First, to best assess how ones ammunition will perform in competition, it should be test-fired at the actual distance for which it will be used. [That means] 600-yard or 1000-yard ammo should be tested at 600 and 1000 yards, respectively, if possible. It is possible to work up very accurate ammunition at 100 or 200 yards that does not perform well as ranges increase. Sometimes, a change in powder type can correct this and produce a load that really shines at longer range.
The number of shots fired per group should be realistic for the course of fire. That is, if one will be firing 10-shot strings in competition then final accuracy testing, at least, should involve 10-shot strings. These will reflect the rifles’ true capability. Knowing this will help the shooter better decide in competition whether a shot requires a sight adjustment, or if it merely struck within the normal accuracy radius of his rifle.
How many groups are needed for a valid test? Here, much depends on the precision with which one can gather the accuracy data. If shooting from a machine rest in good weather conditions, two or three 10-shot groups at full distance may be very adequate. If it’s windy, the rifle or ammunition are marginal, or the shooter is not confident in his ability to consistently fire every shot accurately, then a few more groups may give a better picture of the rifle’s true average.
Sometimes everything comes together — a great barrel, the right load, good bullets, and, of course, a gifted trigger-puller. Check out this target from Forum member Mike Ezell. That’s five (5) shots at 100 yards from Mike’s 30 Major benchrest rifle. When this group was shot a while back, Mike reported: “I fired a few groups in the great weather. No surprises — it did VERY well! My little wildcat, the 30 Major, has always been a shooter. That target was not a fluke — I shot a few groups today and Agg’d a high One.” Mike is a Kentucky gunsmith who builds his own rifles.
30 Major is Based on 6.5 Grendel
What’s a “30 Major” you ask? This is Mike’s own wildcat, a 6.5 Grendel necked up to .30 caliber. Mike writes: “The 30 Major is essentially a .070″-long 30 PPC. With the great 6.5 Grendel brass available from Lapua, all you need to do is neck-up and turn the necks to prep the brass.” Mike says it is very much like a 30 BR, but you just start with 6.5 Grendel brass instead of 6mmBR brass.
The cartridge has one major benefit — it utilizes a PPC-diameter bolt face. That makes it easy to convert your group-shooting 6 PPC to shoot score with .30-cal bullets. Mike explains: “If you have a PPC, to shoot score, all you have to do is chamber up a [.30 caliber] barrel and screw it on your PPC.”
From 7.62×39 Russian to 30 Major — Full Circle
Arms expert Neil Gibson has an interesting perspective on the lineage of the 30 Major. He reminds us that this wildcat has returned to its roots: “Start off with the 7.62×39 Russian [cartridge]. The Russians then modify it, necking it down to .223 for deer hunting. The U.S. benchrest guys then modify that, necking it up to 6mm and blowing the case out making the 6mm PPC. Someone takes that case, necks it out to 6.5 mm, making the 6.5 PPC. Alexander Arms takes that and makes the 6.5 Grendel. Then finally Mike Ezell takes the Grendel and necks it up to 30 caliber, making the 30 Major. From 30 caliber, back to 30 caliber. OK, the original uses .31 caliber bullets, but the bore is still .300. Talk about almost coming round full circle!”

Great Accuracy Restored after Solving Mystery Problem
To get his 30 Major rig shooting this well, Mike had to solve a mysterious problem that cropped up last year. Mike explains: “Two years running, I have finished in the top 15 in IBS points shooting [the 30 Major], but last year’s benchrest season was tough.” Mike was having some accuracy issues that defied explanation. But he figured it out: “The front action screw was bottoming out against the barrel extension – just barely. A simple fix brought the gun back to life. It’s a Stiller Viper Drop Port. The action is screwed and glued into the stock, so I was a bit surprised … especially after having checked for [that issue] while looking for the problem. I’m just glad to have found the trouble so I can begin to re-instill some confidence in the gun and myself, after last year.”

Serious reloaders know that PMA Tool makes some of the best specialty reloading tools you can buy. To help folks get the most out of their PMA products, the company offers “how-to” videos. One such video features PMA’s great Micro-Adjust Case Trimmer. PMA owner Pat Reagin tells us: “We’ve had quite of bit of interest in the case trimmer, but a lot of guys want to see it in action. So we’ve created an intro video that shows how to adjust and use the trimmer in various modes.”
Watch Micro-Adjust Case Trimmer Video
The PMA Micro-Adjust Case trimmer indexes off the shoulder but it also provides precise control over neck length. You aren’t limited to a built-in, neck-length setting like some other shoulder-indexed trimmers. The PMA Micro-Adjust Trimming tool currently sells for $129.95 including one cartridge insert. The inserts, which can be purchased for $13.95 separately, can often work for a multiple cartridge types within the same family. For example, you can use the same insert for both .243 Win and .260 Rem. There is another insert that works with both 7mm-08 and .308 Win.
PMA Micro-Adjust Case Trimmer Features:
Indexes off shoulder for easy, consistent trim length.
Cases captured in no-scratch, Delrin™ inserts.
Fully rotating head with bearing for smooth operation and clean, square cuts.
Sharp carbide cutter for quick, smooth cuts with minimal burr.
Spring loaded head allows complete control of rate of feed.
How to use the PMA Micro-Adjust Case Trimmer
The trimmer indexes case off the case shoulder through the use of interchangeable Delrin™ inserts which capture the shoulder and neck of the case. This insert is contained in a spring-loaded tool head that rides on a linear bearing. The Micro-Adjust Trimmer can be used in three ways.
First, you can secure the case in a PMA caseholder chucked in a power drill, drill press, or lathe. You hold the trimming tool with your hand and feed in the spinning case. (This method is handy because if you leave the case in the holder, after you have trimmed to length, you can switch tools and chamfer the case-mouth using the same power source).
In the second method, the trimmer’s adjustment knob is removed (after locking the setting) and the cutting shaft is chucked in a drill, drill press. or lathe. Using this method, the case itself is held by hand and fed into the cutter. Lastly, the trimmer can be used manually, holding the case in one hand and the trimmer in the other. That’s the slowest method, but it works if you do not have power tools handy.
Ever wondered what caused a particular bulge or marking on a case? And more importantly, does the issue make the case unsafe for further use? Sierra Bullets Ballistic Technician Duane Siercks offers some insight into various issues and their causes in this article from the Sierra Blog.
Incipient Case-Head Separation
This is a Winchester .308 Win case that has a real issue. This case has a very obvious incipient case head separation in the process of becoming a complete failure.
This is most commonly caused by over-sizing the case causing there to be excess headspace on the case. After a few firings and subsequent re-sizing, this case is just about ready to come completely apart. Proper die adjustment is certainly a requirement here. Of course this case is not safe to reuse.
Excessive Pressure (Load Too Hot)
If you will notice in the picture of the case rim, there are two pressure signs to notice. First, look at the primer. It is basically flattened to about the max of what could be considered safe. If this was the only pressure sign noted, I would probably be fine with this load, but would constantly keep an eye on it especially if I was going to use this load in warmer temperatures. This load could easily cross into the “excess pressure” realm very quickly.
There is another sign of pressure that we cannot ignore. If you’ll notice, there is an ejector mark apparent that is located over the “R” of the R-P headstamp. This absolutely tells us that this load would not have been in the safe pressure range. If there were any of these rounds loaded, they should not be fired and should be dis-assembled. This case should not be reloaded.
Split Case-Neck
Here we have an R-P .22-250 case that has died the death. Everything looks fine with this case except the neck is split. This case must be tossed.
A split neck is a normal occurrence that you must watch for. It is caused by work-hardening of the brass. Brass cases get harder with age and use. Brand new cases that are stored for a period of time can become hard enough that they will split like this case within one to two firings. I have had new factory loads do the same thing. Then as we resize and fire these cases repeatedly, they tend to get harder and harder. Eventually they will split. The life of the case can be extended by careful annealing practices. This is an issue that would need to be addressed in an article by itself. Of course this case is no longer usable.
In the classes that I teach, I try to use examples like this to let the students see what they should be looking for. As always, if we can assist you, whether you are new to reloading or very experienced, contact us here at Sierra Bullets by phone at 1-800-223-8799 or by email at sierra@sierrabullets.com.
Dented Case Body
Here we have a Lake City 7.62×51 (.308 Win.) case with two heavy marks/dents in the case body.
This one may be a bit of a mystery. It appears as if this case may have been caught in the action of a semi-auto rifle when the firearm jammed or the case failed to clear during the cycling process. I probably would not reload this case just to prevent any feeding problems. This also appeared to be a factory loaded round and I don’t really see any pressure issues or damage to the case.
It is very important to observe and inspect your cases before each reloading. After awhile it becomes second nature to notice the little things. Never get complacent as you become more familiar with the reloading process. If ever in doubt, call Sierra’s Techs at 1-800-223-8799.

When we first ran this story a while back, it spurred a hot debate, with strong opinions on both sides of the issue. Some guys argued vehemently that volumetric powder dispensing was best — citing the experience of short-range benchresters, most of whom still throw their charges. Others say weighing your charges is best, so long as you have a very precise, and very repeatable scale. We know some of the top 1000-yard shooters weigh their charges to the kernel.
Most competitive long-range shooters weigh powder charges for their handloads. Some even use ultra-precise magnetic force restoration scales to load to single-kernel tolerances. But is weight-based measuring always the best way to fill a case with powder? Another option is volumetric charging. This method fills a precisely-sized cavity with powder and then dumps the charge into the case. A Harrell’s rotary powder measure works this way, as does the sliding powder filler on a Dillon progressive press.
For long-range applications, most people believe that precise weighing of powder charges is the best way to achieve optimal accuracy and low ES/SD. However, those short-range Benchrest guys do pretty darn well with their thrown charges, at least at 100 and 200 yards.
Our friend Dennis Santiago recently observed something that made him scratch his head and wonder about weighing charges. His AR-15 match rifle shot better with volumetric (cavity-measured) charges than with weighed charges dispensed by an RCBS ChargeMaster. Here’s what he reports:
Cavity vs. Dribble (Dennis Santiago Report) I had the chance to compare nominally identical ammunition loaded two ways. These were all .223 Remington match loads using 77gr Sierra Match Kings over 23.4 grains of Hodgdon Varget. Same gun. However I loaded some ammo with charges dispensed with a Lee cavity-style powder measure while other rounds were loaded with powder weighed/dispensed by an RCBS Chargemaster. The cavity-drop ammo (with powder dropped from the Lee unit) was consistently better than the weighed-charge ammo. I have no idea why…
So, ladies and gentlemen — what do you think? Why did Mr. Santiago’s volumetrically-charged ammo shoot better than ammo filled with weighed charges? What’s your theory? Gary Eliseo suspects that Dennis’s Chargemaster might have been drifting. What do you think? Post your theories in the comments area below.

Here’s a great deal on Pacific Tool & Gauge-crafted Rem actions with PT&G bolts. These are new Remington-made actions, blueprinted, with PT&G bolts fitted. Sold by PT&G’s retail outlet Cabin Fever Sports, these are pretty much the same as PT&G’s $640 actions with special promo pricing. The prices for the Right Hand actions are $380.00 to $420.00 depending on bolt face. Cabin Fever Sports also has roughly 20 Left Hand (LH) Rem actions at $399.99. You can choose trigger type and add options, such as bolt fluting, for a few dollars more. Order online, or call in and ask for special pricing.
3. CDNN — Smith & Wesson Model 617 10-Shot Revolver, $699.99
This Editor’s first really accurate handgun was a Smith & Wesson model 617 that could easily stack ten shots in a dime at 10 yards. It remains my favorite and most-used handgun, and I will never part with it. What can we say about the model 617? Every serious gun guy should own one. The single-action trigger pull is superb, and the accuracy surpasses most any semi-auto rimfire pistol, except for a few, very, very expensive target pistols. We like the 6″ version for the longer site radius, but the 4″-barrel 617 is also very accurate, and it balances better. CDNN’s $699.99 sale price may seem like a lot of money, but MSRP is $829.00 and most dealers are charging $750.00 or more for a new 6″-barrel 617. Get one — you won’t regret it.
4. Amazon — Plano Field Locker Double Long Gun Case, $111.50
A full 54″ long inside, this Plano Field Locker Double Long Gun Case will hold big rifles with 30-31″ barrels. The case has tough latches, watertight seals, and wheels for easy transport. Right now this case is just $111.50 with Free Prime Shipping. That’s less than half what you’d pay for a Pelican this big. Buyers confirms this Plano case is capacious and tough: “It holds two 17-lb bench rifles with 30″ barrels… even the airline baggage handlers couldn’t damage this case” (Smitty). “I bought this case for a Savage 110BA .338 Lapua Magnum, and it’s so nice that I just bought a second one for a 50 BMG. There are very few rifle cases that will fit the larger rifles.” (Bruce L.) “I’ve used one case in extensive
field abuse, and it has held up remarkably well. IMO there is not a finer case available on the market for any big-bore center-fire rifle. You can spend more; but I don’t think you can get any better.” (Gene).
5. Monmouth Reloading — 500 Lake City 5.56 Cases, $35.00

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
Sticking 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
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.
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!
