Put the same load in a variety of barrels (with the same length and chamberings) and you’ll see a wide variance in muzzle velocity. In fact, it’s not unusual to see up to 100 fps difference from one barrel to the next. We demonstrated this with a comparison test of Lapua factory ammo.
Chron Testing Lapua Factory Ammo
At our Southern California test range some years ago, we chronographed Lapua 105gr 6mmBR factory ammo in three different 8-twist barrels of similar length. The results were fascinating. Lapua specs this ammo at 2790 fps, based on Lapua’s testing with its own 26″ test barrel. We observed a speed variance of 67 fps based on tests with three aftermarket barrels.
Barrel Velocity Variance
Brand ‘S’ and Brand ‘PN’ were pre-fit barrels shot on Savage actions. Brand ‘K’ was fitted to a custom action. All test barrels were throated for the 100-108 grain bullets, though there may have been some slight variances in barrel freebore. With a COAL of 2.330″, the rounds were “jumping” to the rifling in all barrels.
Among the four barrels, Brand ‘PN’ was the fastest at 2824 fps average — 67 fps faster than the slowest barrel. Roughly 10 fps can be attributed to the slightly longer length (27″ vs. 26″), but otherwise this particular barrel was simply faster than the rest. (Click Here for results of 6mmBR Barrel Length Velocity Test).
IMPORTANT: Results Are Barrel-Specific, Not Brand-Specific
These tests demonstrate that the exact same load can perform very differently in different barrels. We aren’t publishing the barrel-makers’ names, because it would be wrong to assume that ‘Brand X’ is always going to be faster than ‘Brand Y’ based on test results from a single barrel. In fact, velocities can vary up to 100 fps with two identical-spec barrels from the SAME manufacturer. That’s right, you can have two 8-twist, 26″ barrels, with the same land-groove configuration and contour, from the same manufacturer, and one can be much faster than another.
Don’t Demand More Than Your Barrel Can Deliver
We often hear guys lament, “I don’t get it… how can you guys get 2900 fps with your 6BRs and I can only get 2840?” The answer may simply be that the barrel is slower than average. If you have a slow barrel, you can try using more powder, but there is a good chance it may never run as fast as an inherently fast barrel. You shouldn’t knock yourself out (and over-stress your brass) trying to duplicate the velocities someone else may be getting. You need to work within the limits of your barrel.
Factory Ammo Provides a Benchmark
If you have a .223 Rem, 6mmBR, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, 6.5×55, .308 Win, 30-06, or .338 LM Rifle, we recommend you buy a box of Lapua factory-loaded ammo. This stuff will shoot great (typically around half-MOA), and it can give you a baseline to determine how your barrel stacks up speedwise. [Editor’s NOTE: The original test was conducted in 2008. The velocity of current-production Lapua factory ammo might be higher or lower, so your results may vary.]
When you complete a new 6mmBR rifle, it’s definitely smart to get a box of the factory ammo and chronograph it. That will immediately give you a good idea whether you have a slow, average, or fast barrel. Then you can set your velocity goals accordingly. For example, if the factory 6BR ammo runs about 2780-2790 fps in your gun, it has an average barrel. If it runs 2820+ in a 26″ barrel (or 2835 fps in a 28″), you’ve got a fast tube.
Every serious hand-loader benefits from a precise, repeatable, and efficient powder dispensing system. There are many electronic powder dispensers on the market, starting at about $230 for a Frankford Arsenal Intellidropper and $240 for a Lyman Gen6. At the high end, the ultimate powder weighing/dispensing system would be an Auto-Trickler V4 mated to an top-tier electronic Force Restoration scale. Such a system can run $1200 or more, depending on scale cost.
In today’s Saturday video showcase we feature eight videos about electronic powder dispensers, as well as Auto-Trickler systems (both V3 and V4). If you are in the market for a new powder scale/dispenser system, we recommend you watch these videos. You may be surprised by some of the findings, and you will certainly learn more about these machines — their pros and cons. That knowledge can help you decide what electronic powder dispenser best deserves your hard-earned dollars.
Five Powder Dispenser Comparison Test (All Units Purchased)
If you are in the market for a sub-$500 electronic powder dispenser, definitely watch this review. This Backfire comparison test is notable because the tester spent his own money to purchase all five powder dispensers being reviewed. That means Backfire could tell the full truth, both good and bad, about the machines. In fact, Backfire bought TWO ChargeMaster Lites because one failed (See 14:12 time-mark). The reviewer liked the RCBS ChargeMaster Supreme, but his top choice overall was the Hornady Auto Charge Pro. He favored the overall design, and really liked the way the dispensing speeds could be easily set faster or slower. Here are highlights from the video review:
00:08 Speed Test
03:09 Accuracy Test
07:57 Frankford Arsenal Intellidropper
09:08 Lyman Gen 6
10:44 RCBS Chargemaster Supreme
12:03 Hornady Auto Charge Pro
14:12 RCBS Chargemaster Lite
14:41 Conclusions
AutoTrickler V3 vs. Hornady Auto Charge Pro
In the Backfire comparison video above, the Hornady Auto Charge Pro powder dispenser earned top marks among sub-$500 units. Here the Auto Charge takes on some tougher competition — an ultra-precise Force Restoration scale fitted with an Auto-Trickler V3, a system that cost upwards of $1150.00 U.S. Dollars. The Australian duo running the comparison found the Auto-Trickler system was more accurate and consistent. Notably, with a dispense speed of just 14 seconds. the Auto-Trickler V3 system was significantly faster than the Hornady machine. The Auto-Tricker V3 has been superseded by the new Auto-Trickler V4 which retails for $490.00 USD. Add $625 or more for a good Force Restoration scale such as the A&D FX-120i.
RCBS New ChargeMaster Supreme and Other ChargeMasters
In this well-made video, Gavin Gear of UltimateReloader.com does a detailed review of the new-generation RCBS ChargeMaster Supreme. He puts it through his paces, verifying its accuracy and repeatability. He shows how the unit can be programmed. At the 17:20 time-mark, Gavin employs an A&D FX-120i Force Restoration scale to check the ChargeMaster Supreme’s charge-weighing precision. The results were good.
Frankford Arsenal Intellidropper vs. RCBS ChargeMaster Link
The Frankford Arsenal Intellidropper, now just $230 on sale at Midsouth, was very innovative when first released, offering remote Bluetooth access and a wide range of programmable features. The downloadable App stores your load data and has preloaded bullet and powder databases. This video compares the Intellidropper with another Bluetooth-enabled modern powder dispenser, the RCBS Chargemaster Link. A free RCBS App allows you to control settings remotely.
Hornady Auto Charge Pro Review by Ultimate Reloader
As the $350 Hornady Auto Charge Pro dispenser was top-rated in the Backfire comparison at the start of this article, we thought we’d include a detailed review from Gavin Gear of UltimateReloader.com. If you are thinking of buying a Hornady Auto Charge Pro, definitely watch this video, as it is the most thorough Auto Charge Pro review on the web and Gavin is by far the most articulate tester. SEE FULL TEST.
AutoTrickler V4 and Force Restoration Scale
The AutoTrickler V4, paired with a quality Force Restoration scale, is the “Rolls Royce” of electronic powder dispensing systems, offering unrivaled charge-weight accuracy, great repeatability, and ultra-fast dispensing speeds. If you have the budget — $490 for the V4 plus $625+ for scale — the AutoTrickler V4 is a superb system that lets you load extremely accurate, consistent ammo. This detailed F-Class John video shows how to set up the system properly and control the dispensing and trickling functions.
RCBS MatchMaster vs. AutoTrickler V3 with A&D FX-120i Scale
This video is interesting because it compares the most advanced and expensive mass-market electronic dispenser, the $899 RCBS MatchMaster, with an AutoTrickler V3 mated to an ultra-precise Force Restoration scale. The AutoTrickler V3 + scale system offers wicked fast dispensing while delivering near-single-kernel precision and great repeatability. The MatchMaster has some interesting features, including dual dispensing tubes and a special slower, “Match Mode” dispensing function which provides enhanced precision.
BONUS Video: RCBS ChargeMaster Dispenser vs. Four Scales
This video answers the question “How does a common powder dispenser’s weighing accuracy compare to stand-alone scales?” Here the tester compares the weighing precision of an early-model RCBS ChargeMaster with four dedicated scales: A&D FX-120i (Force Restoration), Hornady G2-1500, Hornady GS-1500 (Gen 1), and a WAOAW milligram scale. These scales range significantly in price, with the FX-120i Force Restoration the most expensive by far. The features/prices of the four scales are listed at 4:41 time-mark. Accuracy/repeatability comparison testing with test weights starts at 10:12 time-mark.
Forster offers an innovative item for precision hand-loaders. The Forster Accu-Ring has precise markings so you can set your sizing dies with extreme precision in your press. The annodized black ring has laser-etched contrasting precision markings in .001″ increments. This allows you to more easily set the amount of sizing and shoulder “bump” you get when you move a die up or down in your press.
In addition, if you have a conventional seating die without a micrometer adjustment, this new Forster Accu-Ring can help you achieve more precise bullet seating. SEE Ultimate Reloader Review.
The precision Forster Accu-Ring was tested by UltimateReloader.com. The testers tried the new ring with both a sizing die and and seating die. The test confirmed the ring provides greater precision, compared to conventional die lock rings.
See the Forster Accu-Ring in this Ultimate Reloader product test video:
The product description from Midsouth Shooters explains:
Accu-Ring Cross Bolt Die Lock Ring (Anodized and Laser-Marked)
The Forster Accu-Ring makes setting up your Sizing Die easier by giving you reference marks in thousandth of an inch increments (.001″). To use these reference marks, simply use a fine ink marker to put a point of reference line on your die. Turn the die clockwise to increase the amount of shoulder bump or counterclockwise to decrease the shoulder bump (i.e. increase case’s headspace length).
There are many other factors that could influence the final amount of shoulder bump during sizing. Ductility of the brass or springback, type of case lube used, pulling an expander ball through the neck and the amount of slack in the linkage of your reloading press are a few things that cause variation in shoulder bump of sized cases. The reference marks on your lock ring will help you to zero in on what you want the headspace length of your cases to be.
Remember to lock up the Accu-Ring completely after you make an adjustment before you size a case again. Otherwise you will obtain inconsistent results if the ring is not tightened.
Another use is for non-micrometer seating dies. Instead of guessing with your seating stem, you can make fine adjustments to your seating depths using the Accu-Ring.

Here are a couple of our favorite SSUSA feature stories from recent years. There are hundreds of other informative articles worth reading.
New York state’s cynical response to the landmark NYSRPA v. Bruen case, which affirmed a Constitutional right to carry firearms, was to defy that decision completely. New York’s politicians, lead by authoritarian N.Y. Governor Kathy Hochul, passed legislation (S51001) that put nearly all of the state “off-limits” to persons with carry permits. The goal was to render New York CCW permits essentially useless because CCW use was geographically forbidden throughout the state. Thankfully, Second Amendment advocacy organizations FPC and SAF have now challenged these new restrictions in New York state.
The Firearms Policy Coalition (FPC) has filed a motion for preliminary injunction in Boron v. Bruen*, its lawsuit challenging New York’s “sensitive location” handgun carry bans in public parks, public transportation, and all private property without express consent. The motion can be viewed at FPCLegal.org. That new legislation, S51001, banned carry nearly everywhere, including public buildings, shopping centers, parking lots, train stations, parks, and countless other locations.
The FPC’s lawyers note: “Under S51001, ‘ordinary, law-abiding citizens’ … are again prevented from carrying handguns in public for self-defense in almost all corners of the State, except in what Governor Hochul said were, ‘probably some streets’.” The FPC’s motion to enjoin enforcement of the new law adds that: “S51001 makes a mockery of the Supreme Court’s holding in Bruen, which reaffirmed that personal security “emphatically extends to include ordinary, law-abiding Americans ‘outside the home’.”
“The New York Legislature appears to think that when the Supreme Court closed the door on New York’s may issue permit regime it opened a window for equally onerous location restrictions,” said FPC Director of Legal Operations Bill Sack.

* On September 28, 2022, the original first-named plaintiff, John Boron, has been voluntarily dismissed from the action. Plaintiffs Brett Christian, Firearms Policy Coalition, Inc., and Second Amendment Foundation will continue in the case as plaintiffs. A motion to change the caption and short title of this action has been filed. If that goes through, the lawsuit may be re-titled “Christian et al v. Bruen”.
Reloading components can be hard to find, and bullets and powder are considerably more expensive than a few years back. And while centerfire pistol ammunition has started to come down in price, it is still way more expensive than .22 LR rimfire ammo. For these reasons, more pistol shooters now train with .22 LR rimfire pistols. Along with rimfire ammo’s greater affordability, these shooters often find that they enjoy rimfire’s much lower recoil and reduced noise levels. Fortunately, more gun makers now offer .22 pistols with ergonomics similar to centerfire pistols, making realistic training with a .22 LR very feasible.
SIG Sauer P322 is tested extensively with multiple rimfire ammo brands:
September-October 2022 Tactical Life Issue Features .22 LR Handguns
The September-October 2022 issue of Tactical Life features .22 LR rimfire pistols that have been designed to emulate full-size defensive pistols. With these new-generation, full-size rimfire 22s sharing the same ergonomics as 9mm SIGs and Walthers, this is a good way to train. The cost benefits can’t be denied. With good .22 LR ammo available for under $5.00 per 50-ct box, you can shoot 200 rounds of .22 LR for less than the cost of 50 rounds of 9x19mm centerfire ammo. This lets pistoleros hone their shooting skills, with more target time, at a fraction of the cost.
The latest issue of Tactical Life reviews an interesting selection of .22 LR rimfire pistols. Fred Mastison’s cover story reviews new full-size, semi-auto .22 pistols from FN, Sig Sauer, and Walther. Mastison tests the FN 502, SIG P322, and Walther WMP. Plus, Mastison chronicles 10 other new .22 pistols offered this year.
Tactical Life’s editors observe: “With many kinds of ammunition still very hard to find, available ammo quite expensive and runaway inflation making expendable income for range visits increasingly harder to come by, it’s a good thing that manufacturers have — whether intentionally or not — made 2022 the year of the .22. With a good .22 pistol or rifle and a couple of bricks of ammo, you can shoot all day for what just a few hours of shooting centerfire rounds would cost you.”

Over 30 million Americans participated in target shooting or hunting last year. Notably, there is greater diversity among hunters and target shooters than ever before. In 2021, 32% of target shooters were female, up from 25% a decade ago. And the share of Black or Hispanic target shooters has been increasing 5% and 4% respectively per year.
This interesting information was revealed in a new report released by the Outdoor Foundation and the Council to Advance Hunting and the Shooting Sports. According to that report, the user diversity of hunting and target shooting participation increased significantly in the USA over the past decade.
The 2022 Special Report on Hunting and the Shooting Sports provides a comprehensive look at the more than 30 million Americans who participated at least once in hunting (gun or archery) or target shooting in 2021. Highlights from the new report include:
Firearms Target Shooting Participation:
— 6.2% of the U.S. population ages 6 and over participated in target shooting
— 32% of participants were female, up from 25% a decade ago
— Share of target shooters who were Black or Hispanic increased 5% and 4%, respectively, on average for the past 3 years
— “High cost” was the number one barrier reported for target shooting
— “For recreation” was the number one motivation for target shooting
Hunting Participation:
— 4.6% of the U.S. population ages 6 and over went hunting at least once
— 27% of participants were female, up from 16% a decade ago
— Share of hunters who were Black or Hispanic increased 4% and 1%, respectively, on average for the past 3 years
— 68% of hunters were introduced to hunting by a family members
— 49% of hunters first participated before reaching the age of 18
— “For food/meat” was the number one motivation for hunting
