Based on the questions we get on a daily basis on our 800 (Customer Support) line, twist is one of the most misunderstood subjects in the gun field. So let’s look deeper into this mystery and get a better understanding of what twist really means.
When you see the term 1:14″ (1-14) or 1:9″ twist, just exactly what does this mean? A rifle having a 1:14″ twist means the bullet will rotate one complete revolution every fourteen inches of the barrel. Naturally a 1:9″ turns one time every nine inches that it travels down the barrel. Now, here’s something that some people have trouble with. I’ve had calls from shooters thinking that a 1:14″ twist was faster than a 1:9″ because the number was higher with the 1:14″. The easiest way to remember this is the higher the number, the slower the twist rate is.
Now, the biggest misconception is that if a shooter has a .223 with a 1:8″ twist, his rifle won’t stabilize a 55gr bullet or anything lighter. So let’s look at what is required. The longer a bullet is for its diameter, the faster the twist has to be to stabilize it. In the case of the .223 with a 1:8″ twist, this was designed to stabilize 80gr bullets in this diameter. In truth the opposite is true. A 1:8″ will spin a 55gr faster than what is required in order to stabilize that length of bullet. If you have a bullet with good concentricity in its jacket, over-spinning it will not [normally] hurt its accuracy potential. [Editor’s Note: In addition, the faster twist rate will not, normally, decrease velocity significantly. That’s been confirmed by testing done by Bryan Litz’s Applied Ballistics Labs. There may be some minor speed loss.]
Many barrel-makers mark the twist rate and bore dimensions on their barrel blanks.
Think of it like tires on your truck. If you have a new set of tires put on your truck, and they balance them proper at the tire shop, you can drive down a street in town at 35 MPH and they spin perfect. You can get out on the highway and drive 65 MPH and they still spin perfect. A bullet acts the same way.
Once I loaded some 35gr HP bullets in a 22-250 Ackley with a 1:8″ twist. After putting three shots down range, the average velocity was 4584 FPS with an RPM level of 412,560. The group measured .750″ at 100 yards. This is a clear example that it is hard to over-stabilize a good bullet.

In the case of United States v. Hemani, the U.S. Supreme Court (SCOTUS) ruled unanimously (9-0) that the use of marijuana or cannabis can not be used as a basis to deny a citizen his Second Amendment right to bear arms, and specifically to own a licensed handgun.
In U.S. v. Hemani, the U.S. Supreme Court ruled 9-0 that the federal ban on firearm possession by “unlawful users” of controlled substances violates the Second Amendment when applied to routine marijuana users who are not shown to be dangerous or intoxicated while possessing a gun. This SCOTUS decision affirmed the rule of the Fifth Circuit removing criminal charges against the defendant Ali Hemani.
Case Background & Facts: Ali Danial Hemani, a Texas man, legally surrendered his licensed handgun and pointed agents to his marijuana stash during an FBI search. He was neither accused of using the weapon nor intoxicated while possessing it.
The Charge: The government prosecuted him under 18 U.S.C. § 922(g)(3), which makes it a felony to own a firearm while being an “unlawful user of or addicted to” a controlled substance.
The Challenge: Hemani moved to dismiss the indictment, arguing that this categorical ban violated his Second Amendment rights under the Supreme Court’s Bruen standard.
Supreme Court Decision
The Court found that stripping millions of state-legal marijuana consumers of their fundamental constitutional rights without showing individualized dangerousness stretches too far. Writing for the unanimous Court in the majority opinion, Justice Neil Gorsuch rejected the government’s argument that Founding-era laws against “habitual drunkards” historically justified categorically banning marijuana users from owning firearms.
A concurring opinion by Justice Thomas cites the Firearms Policy Coalition (FPC) amicus brief multiple times to argue that, “[a]s a matter of both original meaning and this Court’s precedents, Congress lacks the power to regulate the possession of firearms solely on the ground that they crossed state lines at some point in the past.”
Support from Both Civil Rights Groups and Gun Rights Organizations:
The case had unconventional alliances, with organizations like the American Civil Liberties Union (ACLU) and the NRA filing briefs in support of Hemani. Here are highlights from the ACLU case report:
The U.S. Supreme Court unanimously held today in U.S. v. Hemani that the government cannot prosecute someone as a felon simply for using marijuana and owning a gun that is securely stored.
In 2023, the federal government charged Ali Hemani under 18 U.S.C. § 922(g)(3), which makes it a felony for someone who is an “unlawful user of” or “addicted to” a controlled substance to possess a firearm. Hemani was charged under this statute as an “unlawful user” based on his use of marijuana and the fact that he owned a firearm that was safely secured in his home. The court held that the government’s prosecution of Mr. Hemani under 18 U.S.C. § 922(g)(3) based on his marijuana use violates the Second Amendment.
“Today’s unanimous 9-0 decision makes it clear that the government cannot make it crime for people to own a gun, which the Supreme Court has held is a fundamental constitutional right, simply because they use marijuana,” said Cecillia Wang, legal director at the American Civil Liberties Union.

Barrel-maker Dan Lilja’s website, RifleBarrels.com has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page you’ll find answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.
NOTE: This article was very well-received when it was first published. We are reprising it for the benefit of readers who missed it the first time.
Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”
Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?
A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.
The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.
And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.
Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.
For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.
Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.
Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.
These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.
The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.
The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.
Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.
Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.
I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.
Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.

For affordable, low-recoil shooting fun it’s hard to beat a semi-auto .22 LR. While Ruger’s 10/22 is the most popular semi-auto .22 LR rifle, many manufacturers are now offering AR-style self-loading rimfire rifles. We like AR-style .22 LR rigs for Rimfire Tactical Matches and 3-Gun cross-training. With an AR-style rimfire rifle you can train with low-cost ammunition while enjoying the same ergonomics, controls, and sighting systems found on your centerfire ARs.
If you shoot service rifle, and want to train at a fraction of the cost of shooting centerfire, a rimfire AR clone makes sense. This allows you to practice with a rifle with the same feel, balance, and ergonomics of your .223 Rem/5.56×45 service rifle.
These rimfire versions of the AR-15 are excellent training tools for 3-Gun and tactical match shooters. You can practice with less expensive rimfire ammo, and save wear and tear on your centerfire ARs. Rimfire AR clones also work great for Rimfire Tactical Matches.
Below we feature a variety of popular .22 LR rimfire AR-style rifles, including the Smith & Wesson M&P 15-22, the Tippman Arms series of rimfire ARs, and the HK 416 marketed by Walther.
Smith & Wesson M&P 15-22
Smith & Wesson has upgraded its M&P 15-22, a fun rifle that we’ve praised in the past. The latest M&P 15-22 Sport MOE SL model (Magpul Original Equipment Slim Line) features a more comfortable handguard, an improved grip, and an adjustable Magpul buttstock. The dedicated .22 LR M&P rifle retains the look and features of the company’s popular M&P rifle line, with the enhanced ergonomics of Magpul furniture. It’s offered with Flat Dark Earth (tan) furniture or dressed in matte black.
Field Testing the Smith & Wesson M&P 15-22
Smith & Wesson’s 15-22 is a nice little rifle. The M&P 15-22 is designed and built as a true .22 LR semi-auto from the ground up, with ergonomics (and most controls) identical to a centerfire M&P 15 rifle. NRA reviewer Colon Noir tested the M&P 15-22 and was impressed: “This gun is unbelievably fun to shoot. There is virtually no recoil. The non-existent recoil makes shooting fast a breeze. Yeah, the magazine is a little quirky… but in the grand scheme of things, this gun feels like a full-out AR-15. The M&P 15-22 makes for a great training companion. I would place this gun in the ‘Fun Box’ — it’s reliable enough that you can have a fun time shooting. I’m picking one up, because it’s guns like these that make you truly realize how fun shooting is.”
Here’s a Video Review of the M&P 15-22 by the NRA’s Colin Noir
Tippmann Arms .22 LR AR-Type Rifles
Tippmann Arms makes a large variety of AR-15 style rimfire rifles. Tippmann also offers “house-brand” .22 LR magazines that work great with virtually all .22 LR ammunition — even the low-cost bulk ammo. To learn more, watch the videos below, which demonstrate the excellent functionality and reliability of the Tippmann AR clones. We also recommend the Shooting Sports USA Review of the Tippman Arms M4.
Owners have been very impressed with these Tippmann .22 LR semi-auto rifles. They are very reliable and have ergonomics/layout identical to a centerfire AR15. That makes them ideal for cross-training. Here are comments from some Tippman .22 LR rifle owners:
“Wanted a dedicated .22 LR to shoot with my 22 suppressor. I have a CMMG .22 LR conversion for use in my ARs. I just didn’t like ‘dirtying’ up my regular ARs shooting rimfire. So I bought the Tippmann. Very impressed with the gun. Runs well, and great quality. And I hear they have great customer service. And unlike some other “22LR” ARs, the Tippman is identical to a regular AR as far as controls, feel, and operation. Great for training, or plinking!”
“The wife and I have been running a Tippmann Redline in matches for a year now. Great rifle and company. Picked-up one of the speedloaders last fall and it makes a huge difference in both speed and comfort. No more sore thumb syndrome from loading those 25-round mags.”
Walther HK 416 D145RS .22 LR Rifle
Walther Arms offered an excellent, high-quality .22 LR AR-15 clone sold with the Heckler Koch (HK) label. The HK 416 D is a good cross trainer with high-quality construction and good reliability. The HK 416 D145RS Semi-Automatic Rifle in .22 L.R. is manufactured exclusively by Walther under license from HK. It is the only genuine HK tactical rimfire replica available.
Today, June 14th, is officially Flag Day. The United States’ stars and stripes flag is honored and celebrated this day every year. The week containing June 14 is also designated as National Flag Week. Wikipedia explains: “Flag Day…commemorates the adoption of the flag of the United States on June 14, 1777 by resolution of the Second Continental Congress. The Flag Resolution stated ‘That the flag of the thirteen United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation’.”
Super Sabre Society notes: “While we have added stars to that original flag as our country has expanded, the ideals it represents never fade — courage, liberty and loyalty“.
America Celebrates Flag Day on June 14 Thanks to Woodrow Wilson
In 1916, President Woodrow Wilson issued a presidential proclamation designating June 14 as Flag Day. On August 3, 1949, National Flag Day was officially established by an Act of Congress. Flag Day is not an official Federal employment holiday with Federal employees off work. However, it is at the president’s discretion to officially proclaim the observance.
Interesting Historical Fact — Today is Also the Birthday of the U.S. Army
June 14 is also a day to celebrate our Army. The United States Army celebrates the U.S. Army birthday on this date, as Congress officially adopted the American Continental Army on June 14, 1775.
If you are looking for a versatile, well-crafted semi-auto .22 LR pistol, here’s an option you should definitely consider — the SIG Sauer P322. Introduced in 2022, this .22 LR rimfire pistol that should be popular with SIG’s centerfire handgun owners and anyone who wants a quality polymer-framed .22 LR pistol. The optics-ready P322 offers excellent ergonomics and 20+1 capacity, making it good for cross-training and fun rimfire shooting.
The P322 is built by SIG Sauer in the USA. It has many premium features, including an optics-ready removable rear sight plate allowing installation of a red dot optic without adapter plates. The P322 offers ambidextrous controls, interchangeable flat and curved triggers, and fiber optic front and rear sights. The P322 even comes with a threaded barrel adapter making it suppressor-ready right out of the box. And with a 20-rd magazine for 20+1 total capacity, the new P322 is the highest-capacity .22 LR pistol in its class. (Plus a 25-rd mag extension is offered).
The P322 is offered in both all-black and stainless-slide versions at affordable prices. Right now the handsome stainless version is just $339.99 at Sportsman’s Warehouse, a $60 savings.

In the video below, Shiraz Balolia takes you through the essentials of fire-forming brass with his custom-made, water-cooled benchrest railgun. Shiraz is a former Team Captain (and member) of the U.S. F-Class Open Rifle Team. Shiraz has competed on the National and World level for more than two decades, and has won multiple major International championships in 1000-yard shooting. In this video he will walk you through fire-forming cartridges in .284 Shiraz, a wildcat based on the .284 Winchester.
Fire-forming properly is a pre-requisite for accuracy in a match rifle. Done right, fire-forming can improve cartridge consistency shot to shot. Creating a fire-forming fixture like this, or even a more basic design, can save you time and potential frustration on the range, Shiraz explains. The key is getting the initial case expansion to match your competition chamber quickly but without generating excessive heat. Follow along as Shiraz takes you through the methodology of fire-forming both in his work shop and on the range.
Here Shiraz Balolia takes you through the essentials of fire-forming brass with his custom-made, water-cooled benchrest railgun.
Along with running the successful Grizzly Industrial enterprise, Shiraz is a top competitor and member of the U.S. F-Open team. He has competed in three world championships. In recent years he captured three straight Canadian National F-Class Championships (READ 3-Peat STORY). So, this guy knows his stuff.
Shiraz shows fellow shooters how to fire-form cases efficiently without burning precious match barrel life. In the video above he uses a custom-designed railgun that employs water cooling for the barrel. This is done with hoses running from a sink, so that cool water is constantly flowing through the barrel jacket.
Shiraz says the fired cartridge are actually cool to the touch because the water-jacketed barrel keeps everything at a moderate temperature. (See video at 8:00)
Good Guide for PRS/NRL Competitors
Currently, PRS/NRL tactical competition is the fastest growing rifle shooting discipline with both centerfire and rimfire matches around the country. Are you thinking of getting started in the Practical/Tactical shooting game? Looking for ways to be more stable when shooting from unconventional positions? Then you may want to read Marcus Blanchard’s Practical Shooter’s Guide (A How-To Approach for Unconventional Firing Positions and Training).
Unlike almost every “how to shoot” book on the market, Blanchard’s work focuses on the shooting skills and positions you need to succeed in PRS and NRL matches and similar tactical competitions.
Blanchard provides clear advice on shooting from barricades, from roof-tops, from steep angles. Blanchard says you need to train for these types of challenges: “I believe the largest factor in the improvement of the average shooter isn’t necessarily the gear; it’s the way the shooter approaches obstacles and how they properly train for them.”
Blanchard also offers good tips on shooting fundamentals. Here’s an example:
Blanchard on Trigger Control
“There will always be some amount of wobble when shooting in positions other than prone, and timing the shot to go off when the reticle is within the target is difficult to accomplish when poor trigger techniques are employed. The most common [mistake] I have seen is ‘slapping’ the trigger. The finger is usually hovering off the trigger, and when the shooter determines that NOW is the time to fire, they quickly pull their finger to the rear and ‘slap’ the trigger. The finger never pulls the trigger in the same place and often provokes a sympathetic contraction of the rest of the muscles in the hand, which results in unwanted movement before the bullet exits the muzzle.”
Author Marcus Blanchard has the credentials. A Marine Corps veteran, Blanchard is a regular Top 10 finisher in Precision Rifle Series events. In 2015 Blanchard was ranked 8th overall (nationwide) in the PRS series at year’s end. In 2016 Blanchard won the New Mexico Precision Rifleman’s Championship.

6.5 Guys Recommend Practical Shooter’s Guide
The 6.5 Guys have reviewed Blanchard’s book and they recommend it highly: “What’s a good book for the beginning shooter who wants to get into long range precision rifle or the intermediate shooter who wants to improve his scores? [The Practical Shooter’s Guide] is particularly useful because it explores firing from various positions and props that are encountered in long range precision rifle [events]. This knowledge is completely missing from more traditional books where the shooter is usually slung up and shooting at a paper target. Marcus… goes into considerable detail about shooting from rooftops, reverse rooftops, side slopes, tank traps, barricades etc. This is the type of information that is very difficult to find. We consider ourselves reasonably knowledgeable shooters and this book provided us with new and useful information.” CLICK HERE for 6.5 Guys REVIEW.
6.5 Guys Review Marcus Blanchard’s Practical Shooter’s Guide
Former USMC scout-sniper Frank Galli explains that there is no voodoo when it comes to precision rifle marksmanship, but there ARE techniques that, when practiced, make the difference between good marksmanship and great marksmanship. Understanding the reasons that a bullet hits or doesn’t hit its intended target at ultra-long distances is a crucial element to learning.
Galli’s explanations of how to understand and compensate for wind speed and direction are excellent. In this book, Galli offers great wind-reading advice.
Published in 2020, Galli’s treatise is four years newer than Blanchard’s book, so it includes more of the latest gear and equipment. Galli’s book covers the fundamentals of precision marksmanship with easy-to-understand methodology. The book follow the same instruction process Galli uses in his live marksmanship classes (CLASS REPORT HERE).
This well-illustrated, 272-page book (2020 ed.) covers the latest equipment (scopes, LRFs, chassis systems, magazines, bags, bipods, tripods) favored by tactical competitors in PRS/NRL type matches.
