Before you load that nice new cartridge brass for the first time, run an expander mandrel down the case necks. This will iron out dents and provide more uniform neck tension. Chose a mandrel diameter that provides appropriate neck tension.
Lapua brass is so good that you’ll be tempted to just load and shoot, if you have a “no-turn” chamber. However, some minimal case prep will ensure more uniform neck tension. Keeping your neck tension very uniform allows more consistent bullet seating. That, in turn, usually yields better accuracy, and lower Extreme Spread and Standard Deviation (ES/SD). Lapua brass, particularly 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win comes from the factory with tighter-than-optimal necks. Before you seat bullets, at a minimum, you should inside chamfer the case mouths, after running an expander mandrel down the necks. The expander mandrels from both Sinclair Int’l and K&M will both leave the necks with enough neck tension (more than .001″) so you can then seat bullets without another operation. We suggest putting a bit of lube on the mandrel before running it down the necks — but remove any lube that gets inside the necks before seating bullets.
Both Sinclair and K&M Tools make a die body specifically to hold expander mandrels. The Sinclair version, is shown above. This $32.99 unit fits caliber-specific expander mandrels ($9.99) which measure approximately .001″ less than bullet diameter for each caliber. This is an updated “Gen II” design that completely captures the mandrel within the die so the mandrel cannot pull out. It also has an O-ring in the die cap that allows the mandrel to self-center within the case neck. Sinclair now offers three sizes of die bodies for expander mandrels: .17 -.338 Caliber (#749-011-715WS $32.99); .357 – .50 caliber (#749-008-843WS, $32.99), and a special .50 Cal die body for large-diameter 50 BMG presses (#749-009-163WS, $39.99). All Generation II dies are machined from stainless steel and the standard diameter 7/8-14 dies include the Sinclair Stainless Steel Split Lock Ring.
Once you run the Sinclair expander mandrel down the necks of Lapua brass, after you account for brass spring-back, you’ll have about .002″ neck tension*. This will make the process of seating bullets go much more smoothly, and you will also iron out any dents in the case mouths. Once the case mouths are all expanded, and uniformly round, then do your inside neck chamfering/deburring. The same expander mandrels can be used to “neck-up” smaller diameter brass, or prepare brass for neck-turning.
Forum member Mike Crawford adds: “These expanders can also reduce runout from offset seating. Prior to bullet seating, expand the sized necks to force thickness variance outward. With the Sinclair system, the necks will springback fine, and will not be pulled out of center. This leaves plenty of tension, and bullets seated more centered. I do this, even with turned necks, to get improved seating.”
Mandrels vs. Expander Balls on Decapping Rods
If you haven’t acquired an appropriate expander mandrel for your brass, but you DO have a full-length sizing die with an expander ball, this will also function to “iron out” the necks and reduce tension. However, using a die with an expander ball will work the necks more — since you first size them down, then the ball expands them up again. Typically (but not always), run-out is worse when using an expander ball vs. an expander mandrel.
* This .002″ tension is what we have observed with Lapua 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win brass. This might vary with much smaller or larger cases, and of course a different brand of brass might yield different results. If you get too little tension with your current mandrel, you can get a smaller-diameter mandrel from 21st Century Shooting. 21st Century even offers low-friction Titanium Nitride-coated mandrels.
Top rifle competitors use the AutoTrickler system because it offers a superior combination of speed and precision in dispensing powder loads. With an AutoTrickler fitted to a compatible lab-grade magnetic force restoration scale, you can achieve single-grain weight consistency with your hand-loads. That kind of load weight uniformity does help deliver low ES/SD that translates to reduced vertical at long range. Adam MacDonald’s AutoTrickler system is so good that it can truly be called a “game-changer” in the precision handloading world.
As good as the AutoTrickler may be, there are some simple ways to keep it functioning better, or to improve your productivity. Here are three videos by F-Class John that provide very helpful tips for AutoTrickler owners. The first video shows general set-up and installation. The second video shows a simple but brilliant trick to speed up the process — use two identical powder measure cups shaved to be the EXACT same weight. In third video, F-Class John shows important maintenance tips to keep your AutoTrickler components running smoothly and quietly.
AutoTrickler V3 — General Set-Up and Operational Advice
In this video, John offers some general advice for setting-up the AutoTrickler system. He explains how you can get the machine optimized. For example he notes that you want to set the initial drop weight (from the powder measure) in an optimal range: “When you set the original drop you need it to be about 1 to 1.5 grains below. Some people set it too close to the final weight they want and it actually doesn’t let the trickler unit work as efficiently, consistently and accurately as it will if you start 1 to 1.5 grains low.”
John also explains how to hook up the cords and how to position the trickler unit. John places his AutoTrickler on a 30-lb piece of granite, with a thin polymer “anti-static” pad on top. John also uses a line conditioner and grounding wire to provide the best electrical flow to the scale and trickler. Interestingly, the granite was an inexpensive “surplus” piece taken from a kitchen top installation.
John also shows how the angle of the trickler unit can be adjusted. Another smart tip involves marking the white trickler tube belt bushing. That makes it is easier to discern slow movement and determine when the trickler is completely stopped.
If you own an AutoTrickler or plan to purchase one, we definitely recommend you watch this entire video.
Are you experience chattering when powder is dispensed? John also explains (3:20 – 5:30 time mark) how to replace a small rubber “wiper” part in the dispenser unit. This can help prevent chattering or kernel-cutting as the powder charge drops into the pan from above.
Use Two Identical-Weight Powder Cups to Load Faster
In this second video, F-Class John shows how you can use TWO identical powder cups to speed up your reloading. This is a VERY clever and relatively inexpensive upgrade. You can use 600-grit wet sandpaper to make the weight of the twin cups absolutely identical. John says: “I just lightly sanded the bottom of these until they both weighed exactly the same on my scale.” He can now use one cup to load a case while the other cup is receiving the next powder charge.
AutoTrickler V3 General Maintenance Tips
If you have been running an AutoTrickler for quite some time, you have probably noticed some noise or vibration. This video shows some very simple maintenance procedures that will have your AutoTrickler running great again. F-Class John reveals some components that can get dirty or worn after considerable use. The video identifies the items that may require a cleaning or adjusting. In the video John shows how to do those tasks quickly and easily.
In the last three minutes of the above video John shows an important process involving the trickler unit motor. The motor’s attachment screws tend to loosen slightly over time. After removing the pulley drive wheel, you want to gently tension the four Phillips screws. Then reattach the wheel and drive belt. Doing this simple process should reduce unwanted vibration.
Written by Sierra Bullets Ballistic Technician Duane Siercks
One of the first things new reloaders notice is that load data varies between reloading manuals. The Sierra Bullets Technicians frequently get inquiries asking us to explain why the load data appears to be inconsistent. This article explains five key factors that can influence published load data.
Example of load data variances for two 168 grain bullets:
Here are five reasons why the load data varies:
The Bullet
Basically, the similarities in the .30 caliber 168 grain Match bullets (for example) end with weight and diameter. The bullets likely have dimensional differences such as bearing surface length. Bearing surface has a large effect on pressure and velocity. There are also differences in boat tail, flat base, ogive and over-all lengths, which each help determine the cartridge over-all-length (COAL). With different COAL’s, we can expect changes in pressure and velocity also. In some calibers there are differences in bullet diameter with different bullet manufacturers.
It is also worth noting that bullet manufacturers do not all use the same copper alloy for their jackets. This produces more or less friction that results in load pressures and velocities. The solid copper bullets also vary quite a bit in comparison to a lead core and copper jacketed bullet.
The Gun
Each gun is unique, even if you are using the same make, model, and caliber. Special consideration should be used to consider that not all firearm chambers are the same either, creating more variables that need consideration. There can be drastic differences in the throat length. This controls the amount of “jump” that a bullet experiences when the cartridge is fired.
The Powder
Within normal manufacturing tolerances, you can see some variation in a given powders burn rate between different lots of the same powder. So naturally when two different Manuals are produced, it would be doubtful that the same lots would be tested.
The Cartridge Cases
New cases are almost always near minimum specs in dimension. A load fired in a new case would likely have slightly more pressure that when fired in a re-sized case. This would certainly be true if we were loading into fire-formed cases that have had minimal re-sizing done. Fired cases that are full length resized most of the time be slightly larger than the new unfired cases. This gives you differences in case capacity. The same powder charge placed within a new case and a full length resized case will produce different pressure levels and probably different velocities.
Conditions
Temperature can cause pressure increases or decreases. Hot temperatures tend to cause pressures to increase, while cold temperatures will usually do the opposite. Humidity and altitude can impact pressures and velocities likewise.
Conclusion
As you can see, an amazing number of variables effect any load combination. With the differences in the manuals, you’re just seeing firsthand examples of what took place when the data was collected with that particular set of components and firearm. Think of a reloading manual as a report. In essence, a reloading manual says, “We tried this particular component combination, and these are the results we obtained.”
Remember that you may or may not reach the same maximum load safely. There is no “one load fits all bullets.” The minimum load data offers a safe place to start. The maximum load data listed should always be regarded as a safety guideline and not necessarily a goal! Your gun should shoot accurately without breaching the maximum load data. The best advice is: always start low and work your load up!

Do you shoot a magnum cartridge? Here are two modern-formulation powders you may want to try: Reloder 23 and 26. We have been particularly impressed with Reloder 23. It has worked well in competition for target cartridges such as the 7mm RSAUM. Reloder 23 is like a slower version of Reloder 16 — a very temp-stable powder which has proven a worthy rival to H4350.
Ever heard of Alliant Reloder 23? Or Reloder 26? These two relatively new European-produced Reloder propellants were introduced in 2014. Most folks haven’t tried these Reloder powders because it took quite a while for the first shipments of RL 23 and RL 26 to arrive in the USA. But now these two new propellants are available in the USA, with substantial inventories in stock at some larger vendors. For example, Powder Valley has both RL 23 and RL 26 in stock now at $23.50 per pound. Many other vendors have ample RL 23, but RL 26 is a bit harder to find.
From our Forum members who shoot large magnum cartridge types with heavy bullets, we have heard good things about both RL 23 and RL 26. Reports from the field indicate that both these powders are delivering impressive velocities with low velocity ES/SD.
What are the characteristics of RL 23 and RL 26? That question was answered by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:
“Let me provide some factual info about these products. Some of the stuff that gets propagated is not correct. Reloder 23 is produced by our Swedish partner Bofors, and Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they are both made by Bofors, so that is incorrect.
I have also noticed people are equating Reloder 23 to Reloder 22, and Reloder 26 to Reloder 25. Both of those statements are definitely incorrect. We do state that the performance of Reloder 23 is similar to Reloder 22, and it is, in general burn speed terms, but they are most certainly not the same. We have worked quite a lot of recipes for Reloder 23, and they are not the same as Reloder 22. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”
Furrier says that RL 23 is NOT sensitive to temperature shifts: “Reloder 23 was developed to bring a truly temp-stable powder to the Reloder 22 burn-speed range using Bofors new process technology. This is the second product developed for us with this TZ® process, the first being AR-Comp™. We see terrific efficiencies, SDs, accuracy and flat temp response from these powders. Please try them, I think you will be impressed.”
This Sunday we mark the passing of a prolific writer, High Master marksman, good father, respected colleague, and reloading guru. Glen Zediker, author of many leading treatises on reloading, gun maintenance, and shooting skills, passed away on October 1, 2020, one month ago today. We mourn this loss. Glen helped this website with advice many times and Glen’s classic Handloading for Competition remains one of our favorite reloading resources. Glen was a “leading light” in the shooting sports world for decades. His books and technical articles have helped countless shooters and hand-loaders. His knowledge of the AR15 platform was unrivaled. He will be missed. Rest in Peace Glen.
In 2015 Glen started a series of articles for the Midsouth Shooters Blog, the Reloaders Corner. Here is a section from his introduction to that series:
Glen Zediker — Author and High Master Marksman Glen posted this in 2015…
“I’ve been ‘at this’ for over 40 years now, and ‘this’ is shooting, handloading, and writing about it for the past 25. My background is competitive shooting, primarily NRA High Power Rifle. From that followed my exploration of handloading and education therein. As an NRA High Power Rifle competitor, I earned a High Master classification, and I did it competing in Service Rifle division.
The whole reason I started writing about all this came about because I couldn’t find anything to read that put the pieces together — all the pieces that all the better shooters knew. I wanted to learn more, and I spent a lot of time and effort doing so. I continually got answers from winners and those who built rifles for winners. Unfortunately, those answers were not the same as I had been reading, and none of the authors of the other material I had read had won any championships. I thought there must be others who would appreciate some short cuts, and that’s how I started my publications career.
I think I’ve helped a few folks along the way.”
From Glen Zediker’s Reloaders Corner
Here is Glen’s advice about loading from his first “Reloaders Corner” Blog article in 2015:
“So, the advice that accompanies this first installment is to consider or reconsider your standards, and your evaluation of what is a good load. When I’m testing I choose the best group out of whatever it was I was testing. However, when it’s decision time, I choose the best, worst group. Let me explain. I really don’t consider what the very best any combination can show me is, but rather what is the worst the combination has shown me. Exceedingly tight groups are all too often a combination of luck and a little more luck. We got lucky in our judgment to choose the combination and the bullet fairy tipped her tiara. The more rounds anyone shoots, the bigger the groups are going to get. That’s just math. However, if three or four 10-shot groups are showing X-Ring accuracy, I’m going to ignore the group measurement, pay more attention to the chronograph, and pay very close attention to any over-pressure indicators. I don’t want to see anything outside a golf-ball sized circle at 300 yards, and I’m hoping to keep it that way.
Speaking of which — years ago, I was a golf pro… a legendary golf instructor, Percy Boomer (real name) had a line, ‘The difference between the amateur and professional is not in the quality of their best shots, but in their worst.’ That’s it. The difference between a good load and one that’s almost a good load is that also. The good load stays tight, throughout. A ‘flyer’ is grounds for disqualification. That’s a shot that strays from the herd. Don’t ignore it.”
Glen Dwight Zediker Obituary
June 17, 1959 – October 1, 2020
Glen Dwight Zediker, died on October 1, 2020, at home in Oxford, Mississippi, with his sons at his side.
Glen was born on June 17, in Rifle, Colorado, to Lloyd and Marie Zediker (both deceased) of Grand Valley (now Parachute), Colorado. He attended K-12 in Grand Valley, studied at the University of Colorado, Boulder, and graduated from the University of Mississippi with a B.A. in English.
Glen spent most of his professional career combining his expertise in target shooting with his skill at writing. He became an NRA High Master known for pinpoint accuracy. He wrote and published several books on target shooting and reloading which are highly respected in the precision shooting community.
Glen spent many years in Mississippi and embraced southern culture from the food to Faulkner, but at his core, he remained a Westerner. He loved nothing more than riding over red dirt hills and hiking in the Southwest.
Glen’s two sons, Matthew and Charlie, were the center of his life. In addition to his sons, he is survived by his sister, Diane Zediker-Pastore (Victor) and his former wife, Kris Kunkler Zediker. See more life history and photos on Glen’s Memorial tribute site.
Read Glen Zediker’s Articles on Reloading and Gun Tech
If you haven’t read any of Glen’s works, you will find a selection of shorter articles on the Midsouth Shooters Blog. This is a good way to sample the scope of Glen’s knowledge of reloading, AR15 technical matters, and service rifle shooting. We’ve enjoyed reading Glen’s articles and we know you will too.
In addition, Glen’s website, Zediker.com, has 20 older articles which you can read in PDF format for free. You can find these at Zediker.com/articles/articles.html. Here are three examples:
By Glen Zediker. Folks who read Handloading For Competition know most of this material, but here it is encapsulated for those who want. It’s the run down on how to load at the range, on the spot, and radically improve your success in working up an ammo recipe.
By Glen Zediker. A lot has changed since the original MKII, but then some things really haven’t. There are new triggers on the market and this article will run down what they are and what I think of them. Drop-ins, pins, and lock-time get their spaces too.
By Glen Zediker. There are three articles on this topic that are separated into barrel cleaning, cleaning and lubrication of the rest of the rifle, and a full component on how to run an AR15 as well as store it unharmed.

Area 419 has just introduced the all-new ZERO reloading press, a 9-station turret press with some very unique features. This press was designed to be the most precise turret ever created. As tested by Gavin Gear of UltimateReloader.com, the new ZERO turret press delivered very impressive shoulder-bump consistency and ultra-low seated bullet run-out (about +/- 0.0005″). The numbers were as good as you can get from a quality single-stage press, so Area 419 did some impressive engineering. We would expect that, as this is an expensive product — MSRP is $1200.00. SEE FULL REVIEW on UltimateReloader.com.
The ZERO turret press lets you install up to nine (9) different reloading dies in the large top turret, which revolves around a central axis. But unlike most turret presses, the ZERO doesn’t have flex or wobble when you’re loading. This is because Area 419 includes a clever system for locking the turret in position after you’ve selected the die from your array. Area 419 also uses a unique system for securing shell-holders (see video at 12:00). This, likewise, adds to the precision of the press.
In the video above, you can see how the turret is secured with a “wedge clamp”. By loosening the wedge clamp you can index the press easily to any station. Then, when you have selected your die, you tighten the wedge clamp again. You can see this important procedure at 13:20 – 13:35 timemark in the video.
ZERO Turret Press Has Very Smooth Operation
Gavin observed that this ZERO turret is both smooth and very precise, thanks to smart engineering and the use of multiple bearings. Area 419 describes the design features:
— Turret (zero-slop) eliminates variability induced when removing and resetting dies
— The turret head holds nine 7/8×14-threaded dies (1-1/4 thread in future)
— Available ram-stroke here is 4.4″, allowing use of very tall cartridge types.
— Adjustable/interchangeable handle setup for maximizing leverage/feel based on operation
— Internally contained primer-catch system, slide-out drawer
Important Features of ZERO Turret Press
1. Press frame: 6061 Aluminum, clear anodized
2. Wedge clamp (locks turret into indexed position)
3. Turret (7075 aluminum and steel construction)
4. Adjustable handle with roller knob (set either left- or right-handed operation)
5. Bearings: Ball bearing plus roller thrust bearings for side plates
6. Ram riding in self-lubricated linear bearing
7. Spent primer catcher drawer
Milled from American billet aluminum and stainless steel, this press employs 14 bearings, including a self-lubricating linear sleeve bearing for the precision-ground 1.25″ ram. The linkage system also glides on bearings providing smooth operation with near-ZERO slop. The oversized ram features a 0.75″-diameter steel arm and ZERO-friction knob. The turret system is located with an oversized ball-detent system and secured using an over-sized, custom-made ZERO-point pull-stud. Locking the turret after indexing require only a half-turn of the supplied T-handle (see photo above). When indexing the turret, repeatability variance of the system should be less than .0005″.
The opening in the press will allow for sizing and seating of cases up to.338 Lapua Magnum, and will accept standard 7/8″ dies and standard shellholders. NOTE: Area 419 will be making and selling shellholders specifically fit to the system later in 2020.
SUMMARY — Impressive Press Delivers Precise Results
Gavin Gear was very impressed with Area 419’s new Zero Press, which he said offers the precision of a quality single-stage with the versatility of a turret: “There will always be people that prefer a traditional single-stage. Where the ZERO will be compelling is to those who want the precision of a single-stage without the need to screw dies in and out. Leaving your dies set can have benefits for precision as well — everything comes back to the ‘same place’ when dies are indexed into position. Screwing dies in and out can impose variation, and variation is the enemy of the ‘white lab coat shooter’. I plan on testing the ZERO press with ultra-high-end dies, and custom dies that I ream to my own specifications. I’m thinking that will show the true potential of this press!”

Sam (L.E.) Wilson actively competed in benchrest matches until he passed. He’s shown here with an Unlimited benchrest rifle of his own design.
If you’ve used hand dies with an arbor press, chances are you’ve seen the L.E. Wilson company name. You may not know that the founder of L.E. Wilson Inc. was an avid benchrest competitor who pioneered many of the precision reloading methods we used today. Known as “Sam” to his friends, L.E. Wilson was one of the great accuracy pioneers who collected many trophies for match victories during his long shooting career. His company continues to innovate — bringing out new products such as the Case Gage Depth Micrometer tool we recently reviewed.
The photo above shows Sam (foreground) with all of his children at a shoot. Behind Sam are Jim, Jack and Mary, shooting in the Unlimited Class. What do they say — “the family that plays together stays together”? Note the long, externally-adjusted scopes being used. Learn more about Sam (L.E.) Wilson and his company on the L.E. Wilson Inc. Facebook Page.
Unlimited Class was Sam’s favorite discipline, because in the “good old days” top competitors normally would craft both the rifle and the front/rear rests. This rewarded Sam’s ingenuity and machining/fabrication skills. In the “build-it-yourself” era, one couldn’t just order up an unlimited rail gun on the internet. How times have changed…
Need a simple, easy-to-use drop chart for your rifle? Something you can tape right to the buttstock? Then check out Hornady’s handy Online Ballistics Calculator. This user-friendly calculator will compute your drops accurately, and output a handy “Cheat Sheet” you can print and attach to your rifle.
Here’s how it works. From the Ballistics Calculator Page, simply input G1 or G7 BC values, muzzle velocity, bullet weight, zero range, and a few other variables.
Click “Calculate” to view the full chart (shown below). Then click “View Cheatsheet” and the simpler, 4-line Drop Chart (shown above) appears. Click “Print” and you’re done!
The online ballistics caculator is easy to use. You can select the basic version, or an advanced version with more data fields for environmental variables (altitude, temperature, air pressure, and humidity). You can also get wind drift numbers by inputing wind speed and wind angle.
Conveniently, on the trajectory output, come-ups are listed in both MOA and Mils — so this will work with either MOA clicks or Mil-based clicks. There are more sophisticated ballistics solvers available on the web (such as the outstanding Applied Ballistics Online Calculator), but the Hornady Calculator is very simple and easy to use. If you just want a basic drop chart, you may want to check this out.
Forum member Danny Reever and this Editor have discussed how novice reloaders can struggle with the fine points of reloading, making errors in seating depth, neck-bushing choice, or sizing their cases. We agreed that a good resource covering more than “Reloading Basics” is sorely needed. Danny reminded me that Glen Zediker’s excellent Handloading for Competition book has been available since 2002. Danny says this may still be the best guide in print for those getting started in precision reloading, though the book is not without flaws.
Danny observed: “I consider this still the best book out there on the subject. I’ve bought a lot of other books only to be sorely disappointed after spending $30-$40 of my hard-earned cash. This book is not one of those! I’ve read and re-read Zediker’s treatise at least four times and refer to it often for advice while reloading. My number one suggestion for those who buy the book is to sit down with a highlighter and read it cover to cover. It’s well-written with a bit of humor and it is not boring.”
Extremely comprehensive, Zediker’s book covers nearly all of the key factors involved in accurate reloading: case sorting, brass prep, load development, neck-sizing, full-length sizing, bushing selection/use, tool selection, priming, powder measurement, and bullet seating. The book also explains how to test and evaluate your ammo, and how to monitor and interpret pressure signs.
There are many “must-read” sections in Zediker’s book, according to Danny: “The section beginning on page 161 dealing with concentricity (and how to achieve it) is excellent. Likewise the Load Limits section discussing pressures offers very valuable advice and info. You should also read Zediker’s commentaries about load testing, powders (burn characteristics etc.), and the effects of temperature.”
Zediker has conveniently provided a detailed summary of his book on the web, complete with table of contents, sample pages (PDF format), and dozens of illustrations. Shown above is just one small section that covers ejectors.
Overall, we recommend Glen Zediker’s Handloading for Competition, though the book definitely could use some updating. Danny says: “Plunk down the [money] and buy this book, you won’t be sorry.” Zediker’s book is available from Amazon.com ($34.99), Midsouth Shooters ($33.49), and Zediker Publishing ($36.95).
Tactical shotguns have been hot sellers in 2020, given the social unrest and need to safeguard home and business. Here is a great shotgun deal. The 
“I’ve been ‘at this’ for over 40 years now, and ‘this’ is shooting, handloading, and writing about it for the past 25. My background is competitive shooting, primarily NRA High Power Rifle. From that followed my exploration of handloading and education therein. As an NRA High Power Rifle competitor, I earned a High Master classification, and I did it competing in Service Rifle division.
“So, the advice that accompanies this first installment is to consider or reconsider your standards, and your evaluation of what is a good load. When I’m testing I choose the best group out of whatever it was I was testing. However, when it’s decision time, I choose the best, worst group. Let me explain. I really don’t consider what the very best any combination can show me is, but rather what is the worst the combination has shown me. Exceedingly tight groups are all too often a combination of luck and a little more luck. We got lucky in our judgment to choose the combination and the bullet fairy tipped her tiara. The more rounds anyone shoots, the bigger the groups are going to get. That’s just math. However, if three or four 10-shot groups are showing X-Ring accuracy, I’m going to ignore the group measurement, pay more attention to the chronograph, and pay very close attention to any over-pressure indicators. I don’t want to see anything outside a golf-ball sized circle at 300 yards, and I’m hoping to keep it that way.
