Over the past 12 months, this article was one of the TOP 20 most-read Daily Bulletin features. We’re reprising it today for those who may have missed it the first time. The above diagram comes from a TiborasurasRex YouTube Video comparing G1 and G7 BC models. CLICK HERE to watch the video.
The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.
Some readers are not quite sure about the difference between G1 and G7 models. One forum member wrote us: “I went on the JBM Ballistics website to use the web-based Trajectory Calculator and when I got to the part that gives you a choice to choose between G1 and G7 BC, I was stumped. What determines how, or which one to use?”
The simple answer is the G1 value normally works better for shorter flat-based bullets, while the G7 value should work better for longer, boat-tailed bullets.
G1 vs. G7 Ballistic Coefficients — Which Is Right for You?
G1 and G7 refer both refer to aerodynamic drag models based on particular “standard projectile” shapes. The G1 shape looks like a flat-based bullet. The G7 shape is quite different, and better approximates the geometry of a modern long-range bullet. So, when choosing your drag model, G1 is preferable for flat-based bullets, while G7 is ordinarily a “better fit” for longer, boat-tailed bullets.
Drag Models — G7 is better than G1 for Long-Range Bullets
Many ballistics programs still offer only the default G1 drag model. Bryan Litz, author of Applied Ballistics for Long Range Shooting, believes the G7 standard is preferrable for long-range, low-drag bullets: “Part of the reason there is so much ‘slop’ in advertised BCs is because they’re referenced to the G1 standard which is very speed sensitive. The G7 standard is more appropriate for long range bullets. Here’s the results of my testing on two low-drag, long-range boat-tail bullets, so you can see how the G1 and G7 Ballistic coefficients compare:
G1 BCs, averaged between 1500 fps and 3000 fps:
Berger 180 VLD: 0.659 lb/in²
JLK 180: 0.645 lb/in²
The reason the BC for the JLK is less is mostly because the meplat was significantly larger on the particular lot that I tested (0.075″ vs 0.059″; see attached drawings).
For bullets like these, it’s much better to use the G7 standard. The following BCs are referenced to the G7 standard, and are constant for all speeds.
Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan.
[Editor’s NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly left off for simplicity.]

The Pew Pew Tactical website has interesting article on rifle and pistol cartridges and bullet types. This contains a large selection of interesting photographs and illustrations. If you load and/or shoot for a wide variety of cartridge types, you’ll find that article well worth reading. It has nearly 50 photographs and more than a dozen short videos. READ FULL Article.
The article also shows all types of pistol bullets, along with a variety of rifle projectiles. It even illustrates multiple types of shotshell cartridges.
The article also explains the basic components of modern cartridges — bullet, case, powder, and primer:

Popular Cartridge Types Profiled
The article provides quick summaries of popular ammunition types including 9mm Luger (9x19mm), .357 Magnum, .40 SW, .45 ACP, .223 Rem, and .308 Winchester. The author’s favorite pistol round is the 9mm Luger: “9mm is my personal favorite and if there was a “Goldilocks” round, this would be it. The very first gun I bought was a 9mm. They’re fun at the range. They’re good for defense. It is the standard round for NATO countries and the majority of police forces around the world. It is mild shooting, can vary in weight from 115 to 147 grains, and has varying stopping power based on the type of bullet.”
This Pew-Pew Tactical guide to cartridge types also provides a quick explanation of cartridge ignition — both centerfire and rimfire: “The rimfire’s primer is built into the rim while the centerfire cartridge has the primer in the center. Pro tip — if you can see a circle in the middle…it’s a centerfire cartridge.”
There are two common types of centerfire primers — Boxer and Berdan. This helpful Wikipedia illustration shows how Boxer, Berdan, and rimfire primers ignite the powder in the cartridge:

Protect Your Hearing — Wear Protection Whenever You Shoot
Noise-induced hearing loss and tinnitus are two of the most common afflictions for recreational shooters and hunters. Everyone knows that gunfire is loud, but very few people understand the repercussions that shooting can have on their hearing until it’s too late.
The better quality suppressors can reduce the noise of a gunshot by 20 to 35 decibels (dB). Good muffs or plugs will reduce sound by 23 to 33 dB. By decreasing the overall sound signature, suppressors help to preserve the hearing of recreational shooters and hunters. Even the most effective suppressors, on the smallest and quietest calibers (.22 LR) reduce the peak sound level of a gunshot to between 110 to 120 dB. To put that in perspective, according to the National Institute for Occupational Safety and Health (NIOSH), that is as loud as a jackhammer (110 dB) or an ambulance siren (120 dB). For normal caliber handguns and rifles, suppressed sound levels routinely exceed 130 dB, just shy of OSHA’s “hearing safe” threshold of 140 dB.
According to Dr. William W. Clark, the current Director of the Washington Univ. School of Medicine’s Audiology/Communication Sciences Program, a “serious threat to hearing comes from recreational hunting or target shooting”. This is in large part due to the fact that many people choose not to use traditional hearing protection devices like earplugs and earmuffs because they want to be able to hear their surroundings. Multiple studies have found that between 70 to 80% of hunters never wear earplugs or earmuffs, and nearly half of all target shooters don’t consistently wear traditional hearing protection. Thus, it should come as no surprise that for every five years of hunting, hunters become seven percent more likely to experience high frequency hearing loss.
This article is based on information from the American Suppressor Association (ASA). Since the ASA’s formation in 2011, three additional states have legalized suppressor ownership and 18 states have legalized suppressor hunting. For more information, visit www.AmericanSuppressorAssociation.com.

California “1-in-30″ Firearm Ban Struck Down in Ninth Circuit Decision
The Ninth Circuit Court of Appeals has ruled that a California law restricting gun purchases to just one every 30 days is absolutely unconstitutional. With a unanimous 3-0 decision, a Ninth Circuit panel held that California’s “one-gun-per-month” gun ban law clearly violates the Second Amendment of the U.S. Constitution. The full Ninth Circuit ruling in Nguyen v. Bonta can be viewed at firearmspolicy.org/nguyen.
“California has a ‘one-gun-a-month’ law that prohibits most people from buying more than one firearm in a 30-day period. The district court held that this law violates the Second Amendment. We affirm. California’s law is facially unconstitutional because possession of multiple firearms and the ability to acquire firearms through purchase without meaningful constraints are protected by the Second Amendment and California’s law is not supported by our nation’s tradition of firearms regulation”, wrote Ninth Circuit Judge Forrest. At the end of the 24-page decision, Judge Forest added: “The Second Amendment expressly protects the right to possess multiple arms. It also protects against meaningful constraints on the right to acquire arms because otherwise the right to ‘keep and bear’ would be hollow.”
Plaintiffs in the case included two FFL gun dealers, the Firearms Policy Coalition (FPC), the Second Amendment Foundation (SAF), San Diego County Gun Owners PAC, and six private citizens including Michelle Nguyen, for whom the case is named.
The Nguyen v. Bonta lawsuit challenged the California statute that only allows for the purchase of one handgun or semi-automatic centerfire rifle, from a licensed dealer within a 30-day period. Plaintiffs secured a summary judgment win at the District Court, which California then appealed to the Ninth Circuit. The Ninth Circuit affirmed the District Court decision, striking down the gun rationing law as impermissible under the Second Amendment.
Firearms Policy Coalition Praises Result
“As this decision shows, the right to keep and bear arms cannot be limited by an arbitrary cap on the number of guns that can be acquired at one time”, explained FPC President Brandon Combs. “We have a right to buy more than one gun at a time just as we have a right to buy more than one bible at a time. FPC is proud to have secured the rights of peaceable people and will continue to fight forward until we eliminate immoral laws like this everywhere.”
Second Amendment Foundation Predicts Progress in Fighting California Gun Laws
“Today’s decision claws back a portion of Second Amendment rights stolen by California’s government”, said SAF Exec. Director Adam Kraut. “California’s one-gun-per-month law was in clear violation of the Second Amendment, as affirmed by the unanimous decision in the Ninth Circuit. This ruling is one step closer to liberating the people of the state from the totalitarian ideals of those in power who believe the right to keep and bear arms is a second-class right.”
“There was no doubt the one-gun-per-month restriction was put in place to circumvent the ability of citizens to exercise their full Second Amendment rights,” said SAF founder and Exec. V.P. Alan M. Gottlieb. “This ruling is a victory for all who believe in the fundamental right to keep and bear arms[.]”
Ace tactical shooter and gunsmith Jim See of Elite Accuracy LLC has tested a Frankford Arsenal rotary brass tumbler. Like the older Thumbler’s Tumblers, this can tumble your cases in a liquid solution. The wet-tumbling process worked very well Jim reports. Posting on Facebook, Jim noted: “I was super impressed with the Frankford Arsenal rotary tumbler and cleaning packs they sent me. I ran 350 pieces of brass for one hour. They now look great.” Jim appreciated not having to deal with dry tumbling media, such as crushed walnut shells. Dry media produces dust and can leave residues or clog flash-holes.
Interestingly, Jim recommends you try wet-tumbling WITHOUT using stainless media. At least give it a try. Tumbling without media simplifies the process and you don’t have to worry about pins stuck in flash-holes or case-necks*. Jim reports: “Stainless steel pins come with the Frankford kit, but mine hit the trash right out of the box. There is no need to clean the inside of your cases 100% and that’s all the pins add to the equation. The brass bumping brass with hot water and Frankford’s liquid cleaner works great all by itself.” One wag stated: “That’s great to hear. Stainless steel pins are a PITA.”
Other Facebook posters concurred with Jim’s evaluation of the Frankford Arsenal Rotary Tumbler:
“I’ve had one for a couple years, and it works well. I usually run about 250-300 Dasher cases at once in it. But I use the pins because I’m OCD about clean brass.” — David W.
“I’ve had one for a year and a half and it definitely works with or without pins.” — Luke C.
“I got one about six months ago and have yet to use any stainless steel media [pins]. I just use some dawn, distilled water, and Lemi Shine®. Turns nasty 5.56 range brass bright and shiny.” — Brian D.
“I don’t use the pins either and use a combination of Dawn soap and Lemi Shine.” — Jon N.G.
This video shows how to assemble and operate the Frankford rotary tumbler. But note, Jim See does NOT feel that it is necessary to use stainless media.
How to Dry Your Brass — Hair Dryer Vs. Machine
The downside of wet tumbling is that you end up with a pile of wet brass at the end of the cleaning cycle. There are many ways to dry brass, from drying in the sun to using a kitchen oven (be careful not to “overcook” your brass). One Facebook poster asked Jim: “What is your drying method for wet brass, and how long does it take?”
Jim See replied: “To start I just drain off the dirty water, and rinse the brass with clean hot water. Then I roll the brass on a towel for 30 seconds and put the brass in a one-gallon bucket. Next I insert a hair dryer in the bucket (with the brass) and let it run for about 5 minutes. With this procedure, the drying process for me is done in less than 10 minutes.”
Jack Lanhart has another method: “I use a food dehydrator. It takes 30 to 45 minutes.”
For those who don’t want to mess with towels and hair dryers, Frankford Arsenal offers a matching Platinum Series Case Dryer that simplifies the process of drying brass. Lyman also makes an excellent Cyclone Case Dryer. These drying machines each cost about $65.00 and both have multiple levels so you can separate different types of cartridge brass. Lyman states that “The forced heated air circulation of the Cyclone will dry your brass inside and out within an hour or two, with no unsightly water spots.” The Lyman dryer can also be used for ultrasonically-cleaned gun parts.
*The Frankford Rotary tumbler does include media separators if you choose to use the provided pins or other media. CLICK HERE for diagram showing how to use media separators.
This story first ran in 2010. But to mark our long-standing friendships with shooter Joe Friedrich and chassis builder Gary Eliseo, we wanted to reprise the article for 2025. Joe’s Eliseo-chassis 6mmBR rifle delivered some of the most amazing 100-yard accuracy with factory ammo we’ve ever seen, in any rifle, in any caliber. This gun produced groups in the “ones” with Lapua factory ammo. Read on to learn more.
Amazing Accuracy from 6mmBR Tubegun
What kind of accuracy do you think a tubegun can deliver with factory ammo — during barrel break-in? Perhaps 0.6″ at 100 yards, half-MOA if the conditions are perfect? Well you may want to change your preconceptions about tubeguns — and factory ammo. This Eliseo R5 repeater, smithed by John Pierce with a Pierce CM action and Broughton 5C barrel, shot the Lapua 90gr factory ammo into flat ONEs during the break-in session. A day later, in tricky 8-14 mph winds, the gun nailed a witnessed and software-measured 0.174″ 5-shot group using the 105gr factory ammo. That would be impressive for a “full-race” benchgun with precision handloads. For an across-the-course rifle shooting factory ammo, it’s pretty amazing.
Eliseo Tubegun Shoots in the Ones
This accurate rifle belongs to our friend (and designated expert trigger-puller) Joe Friedrich. During the initial break-in session, since his reloading dies had not yet arrived, Joe decided to start with some Lapua factory-loaded 6BR ammo he had on hand. After doing a few two-shot-and-clean cycles (with patches and nylon brush), Joe decided to try a 3-round group just to see if the Broughton barrel had some potential. To his astonishment, the Eliseo R5 put three rounds in 0.100″ (photo below left). Joe then cleaned the barrel again, shot a couple foulers and tried a 4-shot group. The results were just as stunning — 4 shots in a mere 0.104″ but three in virtually one hole (photo below right).
You Can’t Believe How This Gun Shoots
Joe called your Editor and said “You can’t believe how this gun shoots with factory ammo!”. So we arranged a photo session for the next afternoon, where I could verify the rifle’s accuracy. Well it turned out the conditions were way more challenging than when Joe broke in the barrel the day before. Winds were running 8-14 mph and were swinging through 180 degrees half-way down the range. Joe fired a few 90s through the Oehler chronograph at my request, then opened a box of Lapua 105gr factory ammo. It took about four rounds for the barrel to settle in after being cleaned the night before. Then Joe got serious, and with your Editor looking over his shoulder, he drilled a 0.174″ five-shot group in switching winds, doping every shot. Joe felt the gun could have shot tighter but he missed one wind call.
Serious Accuracy with a Multi-Purpose Rifle
So there you have it — a tubegun that shoots in the ones with factory ammo. Joe says that, at least with the 90s, the Elesio R5 shoots as well as his 6 PPC. Joe stressed that “steering the tubegun is hard work. You really have to concentrate compared to a purpose-built bench gun like my PPC. With the tubegun, everything has to be perfect on every shot — hand position, cheek position, stock position in the bag. If you’re off just a little bit, it’s easy to steer the gun the wrong way and send a shot out of the group.”
Accuracy Great But Fouling Heavy and ES Could Be Better
Have there been any negatives to Joe’s 6BR tubegun experiment so far? Well, the Broughton 5C barrel, while phenomenally accurate, shows signs of being a bad fouler. Copper built up pretty quickly over the first 25 rounds or so. We saw best accuracy with a recently-cleaned barrel. Hopefully the fouling will lessen as the barrel polishes in with use. And the canted land barrel is slower than average with the factory ammo. Lapua rates its 90gr naked-bullet ammo at 2950 fps with a 26″ tube. In Joe’s 27.5″ barrel we only averaged 2901 fps. With the 105gr factory ammo, which is rated at 2790 fps, we averaged just 2694 fps. That’s quite disappointing. Also the ES on the factory ammo, slightly over 50 fps for both bullet types, wasn’t particularly good. Still, the overall results were stunning. This gun shoots better than many long-range benchrest rifles running carefully-developed handloads — and it does that with factory ammo, right out of the box.
Rimfire Benchrest Plus N50 Competition — Fun and Affordable
Joe Friedrich is a superb benchrest shooter, who has won many matches and set National Records in ARA rimfire benchrest competition. Here is Joe with “Sweet Pea”, his favorite .22 LR rimfire rig. With over 100,000 rounds through the Benchmark barrel, this well-worn rifle set an ARA 4-target Aggregate record! READ about Sweat Pea Record HERE.
The National 50 Benchrest League
Joe Friedrich is one of the founders of the National 50 Benchrest League (N50). Launched just a few years ago, N50 has easy-to-understand rules, and offers competition with a wide variety of rifles, both .22 LR rimfire rigs and air rifles. There are three classes — Pellet, Sportsman, and PRO. One can be very competitive in the Sportsman Class with a basic factory .22 LR rig or Air Rifle.
The 2025 N50 National Championship will take place August 22-24, 2025 at the NRA Whittington Center in New Mexico. Benchrest competition will be held at Whittington Coors Benchrest range, on the west side of the Whittington facility. CLICK HERE to register for the August event.
N50 competition is unique in allowing air rifle shooters to compete side-by-side with rimfire shooters. This allows folks to compete without the cost of expensive “top-dollar” rimfire ammo. Pellets are relatively inexpensive, and yes air is still free!
About N50 — The National 50 Benchrest League
Commentary by Joe Friedrich, Open Grove Benchrest
The National 50 Benchrest League (N50) offers a unique shooting experience. We shoot air rifles with pellets and slugs alongside .22 LR Rimfire shooters. We currently have sanctioned clubs throughout the USA offering competition and good fellowship.
N50 has three Classes: Pellet, Sportsman, and PRO. The first Pellet Class is strictly for pellet airguns ranging in calibers from .177-.30 using Diabolo-style pellets from various manufacturers.
The second class is the Sportsman Slug/Rimfire. This combined class allows any factory air rifle shooting commercially-made slugs in calibers from .177-.30 to compete against any factory rimfire that utilizes a factory-barreled action with no attachments to barrel. Pellet air rifles may also compete in this class.
The third class is the PRO Class, and no you do not have to have some magic card that says “Professional” to compete. This class allows purpose-built air rifles, and what we call “unlimited” rimfire rifles to compete. Three types of loads are allowed in PRO Class: .177 slug air-driven, .22 slug air-driven, and any .22 LR ammunition.
Another point — in N50, competitors are allowed to move up in class — you aren’t restricted to a “lower” division. For example, Pellet Class shooters can also move up to shoot in Sportsman and Pro. In addition, Factory rimfires are allowed in Pro Class. This way shooters with the less-expensive rifles can shoot more relays and also see how they compete with the unlimited rigs. It’s all about having fun.
We wanted to make N50 as simple as we could combining air rifles with rimfire so folks who have a factory rimfire can participate and have fun. We also did not want a lot of classes, so combining the two gun types would be simpler.

National 50 Benchrest League Rules and Targets
The official N50 website, National50.net, lists N50 rules, classes, courses of fire, and membership requirements. Downloadable practice and Match targets are also available (scroll down linked page).
Assembly Diagram: Here are all the components of the target frame. The overall maximum assembled dimensions are roughly 26″ wide, 41″ deep, and 66″ tall (the cardboard is 2 x 3 feet).
One of the easiest ways to build a portable target stand is to use PVC pipe and connectors. Utah .308 Shooter “Cheese” has created a simple yet sturdy target frame, and he’s shared his design so you can build a similar frame easily and at low cost. The components are wood furring strips, 2″-diameter PVC pipes (and connections), and a 2’x3′ sheet of cardboard. The PVC base can be glued together, or, for easier transport and storage, you can leave some or all of the connections free. “Cheese” tells us: “I didn’t glue any of it together so I could disassemble it, shove it in a bag and take it anywhere.”
“All the parts are just pushed together and not glued. That way I can break it down and carry it all in a bag. Also, if a buddy (not me!) happens to shoot the stand, I can easily replace just the damaged piece. The last 6 inches of the furring strips are wittled-down a bit so they can be pushed into the upright pipes with a little friction. The cardboard is 2 x 3 feet, and I use a staple gun to attach it to the furring strips. Then I just staple the target onto the cardboard and go at it.
Of course you can modify the dimensions as desired. I chose the black ABS pipe over white PVC simply for cost — black ABS is a little cheaper. You can also glue some or all of the parts together, it’ll just be larger for transporting. In windy conditions, the thing likes to come apart. Duct tape might work well.
For weight, I thought about filling the two end pipes with sand and gluing test caps on each of their ends. The test caps still allow the pipes to slip into the elbows.”
Add Anchors or Internal Weight for Stability
On a very windy day, a PVC stand can shake or even topple over. There are a couple solutions to this. Some people fill the PVC pipe sections with sand to add weight, or you can put short sections of Re-BAR inside the long legs. One GlockTalk forum member noted: “I built [a frame] almost identical to this. I also take four pieces of wire coathanger bent into an inverted “U” shape to anchor the frame to the ground. It is so light that wind will knock the stand over [without anchors].”
You can find photos of a similar home-made PVC target stand (with a slightly different rear section) on the Box of Truth website. This also employs a PVC tubing base with wood uprights. We’ve also seen all-PVC target stands, but we’ve found that it is easier to attach the cardboard to wood strips than to PVC pipe. Also, if the upper section is wood, you can fit different height targets, while using the same base.
The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.

One of the easiest ways to build a portable target stand is to use PVC pipe and connectors. Utah .308 Shooter “Cheese” has created a simple yet sturdy target frame, and he’s shared his design so you can build a similar frame easily and at low cost. The components are wood furring strips, 2″-diameter PVC pipes (and connections), and a 2’x3′ sheet of cardboard. The PVC base can be glued together, or, for easier transport and storage, you can leave some or all of the connections free. “Cheese” tells us: “I didn’t glue any of it together so I could disassemble it, shove it in a bag and take it anywhere.”
