Improve Your Shooting Skills with Multi-Discipline Training

Michelle Gallagher Cross Training

Guest Article By Michelle Gallagher, Berger Bullets
Let’s face it. In the world of firearms, there is something for everyone. Do you like to compete? Are you a hunter? Are you more of a shotgun shooter or rifle shooter? Do you enjoy running around between stages of a timed course, or does the thought of shooting one-hole groups appeal to you more? Even though many of us shoot several different firearms and disciplines, chances are very good that we all have a favorite. Are we spreading ourselves too thin by shooting different disciplines, or is it actually beneficial? I have found that participating in multiple disciplines can actually improve your performance. Every style of shooting is different; therefore, they each develop different skills that benefit each other.

How can cross-training in other disciplines help you? For example, I am most familiar with long-range prone shooting, so let’s start there. To be a successful long-range shooter, you must have a stable position, accurate ammunition, and good wind-reading skills. You can improve all of these areas through time and effort, but there are other ways to improve more efficiently. Spend some time practicing smallbore. Smallbore rifles and targets are much less forgiving when it comes to position and shot execution. Long-range targets are very large, so you can get away with accepting less than perfect shots. Shooting smallbore will make you focus more on shooting perfectly center shots every time. Another way to do this with your High Power rifle is to shoot on reduced targets at long ranges. This will also force you to accept nothing less than perfect. Shoot at an F-Class target with your iron sights. At 1000 yards, the X-Ring on a long range target is 10 inches; it is 5 inches on an F-Class target. Because of this, you will have to focus harder on sight alignment to hit a center shot. When you go back to the conventional target, you will be amazed at how large the ten ring looks.

Also, most prone rifles can be fitted with a bipod. Put a bipod and scope on your rifle, and shoot F-TR. Shooting with a scope and bipod eliminates position and eyesight factors, and will allow you to concentrate on learning how to more accurately read the wind. The smaller target will force you to be more aggressive on your wind calls. It will also help encourage you to use better loading techniques. Nothing is more frustrating than making a correct wind call on that tiny target, only to lose the point out the top or bottom due to inferior ammunition. If you put in the effort to shoot good scores on the F-Class target, you will be amazed how much easier the long-range target looks when you return to your sling and iron sights. By the same token, F-Class shooters sometimes prefer to shoot fast and chase the spotter. Shooting prone can help teach patience in choosing a wind condition to shoot in, and waiting for that condition to return if it changes.

Benchrest shooters are arguably among the most knowledgeable about reloading. If you want to learn better techniques about loading ammunition, you might want to spend some time at benchrest matches. You might not be in contention to win, but you will certainly learn a lot about reloading and gun handling. Shooting F-Open can also teach you these skills, as it is closely related to benchrest. Benchrest shooters may learn new wind-reading techniques by shooting mid- or long-range F-Class matches.

Michelle Gallagher Cross TrainingPosition shooters can also improve their skills by shooting different disciplines. High Power Across-the-Course shooters benefit from shooting smallbore and air rifle. Again, these targets are very small, which will encourage competitors to be more critical of their shot placement. Hunters may benefit from shooting silhouette matches, which will give them practice when shooting standing with a scoped rifle. Tactical matches may also be good, as tactical matches involve improvising shots from various positions and distances. [Editor: Many tactical matches also involve hiking or moving from position to position — this can motivate a shooter to maintain a good level of general fitness.]

These are just a few ways that you can benefit from branching out into other shooting disciplines. Talk to the other shooters. There is a wealth of knowledge in every discipline, and the other shooters will be more than happy to share what they have learned. Try something new. You may be surprised what you get out of it. You will certainly learn new skills and improve the ones you already have. You might develop a deeper appreciation for the discipline you started off with, or you may just discover a new passion.

Barrel End Threading — Bigger Diameter is Better

Barrel Threading AR15 ARX Robert Whitley bartlein

Our friend Robert Whitley of ARX Enterprises LLC has learned, through careful measurement and testing, that some barrels threaded 5/8″ x 24 TPI at the muzzle may not deliver optimal accuracy. The reason is that the end of the barrel can bell out slightly, like a trombone, because too much steel has been removed. This is particularly true with .30-caliber barrels, but it can also be a problem with smaller caliber barrels (even 6mm). Robert demonstrates this phenomenon in the video below. All gunsmiths, and anyone considering threading a barrel, should watch the video. At 1:00 – 1:30 Robert gauges a 5/8″ x 24-threaded .30-Caliber barrel. You can see the belling effect clear as day.

Barrel Threading AR15 ARX Robert Whitley bartlein

“When setting up a commercial barrel in the lathe, we noticed that the maximum-sized bushing that would fit in the bore at the chamber end was almost .0015” smaller [than what would fit] at the muzzle. That precipitated my pin-gauging of a number of different commercial barrels that were threaded for 5/8” x 24 tpi. What I found is what’s shown on the video.” – R. Whitley

Solve Problem with a Larger Thread Diameter
If 5/8″ x 24 threading is potentially harmful to accuracy, is there a solution? Yes, you simply need to leave a little more steel on the barrel. (See Video starting at 02:40.) Frank Green of Bartlein barrels states: “We get these questions all the time. I say run the largest thread diameter that is possible.” Robert Whitley has found that a 3/4″ x 28 TPI threading does not cause the “belling effect”. Accordingly Robert recommends 3/4″ x 28 if you need to thread your barrel for a muzzle brake or suppressor. Robert explains: “We only make 3/4” x 28 TPI muzzle brakes and that’s what we recommend to customers.”

Barrel Threading AR15 ARX Robert Whitley bartlein

“See how much meatier the 3/4″ threading is vs. the 5/8″. The 3/4″ threading offers a lot more metal around the bore. There’s a lot less opportunity for the bore to become bell-mouthed…” – Robert Whitley

Barrel Threading Diameter — What’s Important to Know

By Robert Whitley
In truth, the 5/8″ x 24 TPI threading never came out of any accuracy-based think tank or set-up, it’s a military .30-Cal threading for barrels that someone has to carry around (they needed to keep the barrel weight down so it was smaller in diameter and the threading had to work with that situation). People have somehow assumed because the military uses that threading for certain things that it must mean that it’s also fine for a highly accurate rifle too, but that’s not really correct.

I don’t think there is any better and realistic option than the 3/4″ muzzle threading, and we also do it so there is no relief cut behind the threads on the barrel (i.e. put the relief cut on the brake or jam nut, don’t chop down on the muzzle of the barrel). For some reason many have a hard time grasping that the metal at the muzzle end of a rifle is “sacred” and you should not cut it down any more than absolutely necessary. A little threaded pencil diameter nub on the end of a barrel is not ideal for accuracy especially if it’s threaded and you need to torque on it. I cringe when I see a barrel with something like an MTU or Heavy Varmint contour, only to have an itty-bitty pencil thin threaded nub right at the muzzle so someone can “screw on a can” or a muzzle brake.

Lessons Learned Over the Years
A number of years ago I did a 30BR rifle project with Craig Kostyshyn who was big in the 30BR game and he made some of the best 30BR rifle barrels for benchrest competition. When I did the project I wanted a medium-heavy Palma type contour barrel I could use and also have a muzzle turndown for a front sight band. When he found out I was going to have the muzzle turned down he said “whoa, I need to provide for that when I make the barrel because if you turn the front down later you’ll be shooting a trombone” (i.e. the muzzle bore dimension would open up).

What he did was rough contour the barrel with the turndown (about .010” oversize) before he lapped the barrel, then when he lapped the barrel he took it easy in the muzzle area and worked the back of the barrel more. I thought he was a little bit excessive in his concerns but the barrel shot great and I wasn’t going to argue with him, after all he was shooting groups in the ones. I kind of just filed that away and never thought about it until recently when I went to have Fred from Sabreco do some chamber re-work on a commercial .30-caliber barrel I had. When setting up the barrel in the lathe and indicating things Fred noticed that the maximum-sized bushing that would fit in the bore at the chamber end was almost .0015” smaller [than what would fit] at the muzzle and he mentioned it to me. That precipitated my pin-gauging of a number of different commercial barrels I had that were threaded for 5/8” x 24 TPI. What I found is what’s shown on the video.

CMP Will Commence Modified M14 Sales in January 2027

CMP M14 rifle sale january 2027

Interested in a semi-auto M14 for $2K or less? That would be a very impressive addition to any gun collection (and cost less than a similar Springfield Armory M1A). The CMP has acquired a massive number of military full-auto M14s that are currently being converted to semi-auto functionality. But these rifles retain the stocks, action blocks, and barrels of the originals so they remain very collectible. You should be able to get one of these historic M14s for under $2000.00 with units starting to ship in January 2027. There is no active order page yet for the CMP M14 rifles. CLICK HERE for CMP Official M14 Announcement.

CMP CEO and board chairman Jerry O’Keefe has stated that eventually over 100,000 M14s will be offered for sale, at prices under $2000.00 with a limit of two (2) M14s per buyer per year. Prior to sale, the rifles will be modified to be permanently and irreversibly semi-automatic rifles.

CMP M14 rifle sale january 2027

The CMP has stated that the modified M14s will start shipping in January 2027, just 4.5 months away. Why January? The CMP initially stated the first orders would ship in late 2026. However the massive positive response convinced the CMP that more time would be required to build a substantial inventory of converted M14 rifles. CLICK HERE for Shooting Sports USA article with details. NOTE: Purchasers must comply with CMP Sales Eligibility Requirements.

The CMP plans to modify its surplus M14 military rifles, making them permanently semi-auto rather than fully automatic as originally issued. These converted semi-automatic M14s will then be offered for sale through the CMP sales department in early 2027. Do note that the Springfield M1A, basically a civilian version of the M14, has been available for many years. However, this is the first time true, historic military M14s will be sold to the public, albeit after conversion to semi-auto function.

About the M14 Rifle — Military History
The American M14 is a direct descendant of the M1 Garand rifle. The full-auto M14 is a 7.62×51 rifle that was officially adopted as the U.S. Army’s service rifle in 1957. While the M14 was no longer the standard-issue rifle by 1970 — having been replaced by the M16 — M14 variants were used until the late 1980s, often as sniper rifles.

CMP M14 rifle sale january 2027

The M14 was developed at Springfield Armory as an upgraded, select-fire evolution of the M1 Garand rifle. M1 designer John Garand worked on the transition and final designs — such as the magazine system — before retiring, while other engineers added features including the gas system and automatic fire capability. The M14 uses an interior receiver and general layout heavily based on the M1 Garand.

.308 Win Velocity Change with Barrel Cut Down from 28″ to 16.5″

rifleshooter.com barrel .308 win cut-down test saw ammo GMM velocity magnetospeed

With barrels, one wonders “Can a little more length provide a meaningful velocity gain?” To answer that question, Rifleshooter.com performed an interesting test, cutting a .308 Win barrel from 28″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .308 Win factory ammunition were chronographed at each barrel length.

This is a very useful test is you’re thinking about building a .308 Win hunting rifle, or perhaps thinking of going shorter for your F-TR rifle to save weight.

rifleshooter.com barrel .308 win cut-down test saw ammo GMM velocity magnetospeed

READ RifleShooter.com .308 Win Barrel Cut-Down Test Article.

Test Barrel Lost 22.7 FPS Per Inch (.308 Win Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. With a barrel reduction from 28″ to 16.5″, the average speed loss of the four types of .308 ammo was 261 fps total. That works out to an average loss of 22.7 fps per inch. This chart shows velocity changes for all four ammo varieties:

rifleshooter.com barrel .308 win cut-down test saw ammo GMM velocity magnetospeed

Summary of Findings:
The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS. By ammo type, the average FPS loss per inch was: 24.6 (Win 147 FMJ), 22.8 (IMI 150 FMJ), 20.9 (Fed GMM 168gr), and 22.5 (Win 180PP).

Interestingly, these numbers jive pretty well with estimates found in reloading manuals. The testers observed: “The Berger Reloading manual says for the 308 Winchester, ‘muzzle velocity will increase (or decrease) by approximately 20 fps per inch from a standard 24″ barrel’.”

How the Test Was Done

The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Since we would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut, we decided to eliminate gathering data on group sizes. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 47° F.”

rifleshooter.com barrel .308 win cut-down test saw ammo GMM velocity magnetospeed

CLICK HERE to Read the Rifleshooter.com Test. This includes detailed charts with inch-by-inch velocity numbers, multiple line charts, and complete data sets for each type of ammo. Rifleshooter.com also offers ballistics graphs showing trajectories with different barrel lengths. All in all, this was a very thorough test by the folks at RifleShooter.com.

Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″, we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel start length was 5″ longer than Rifleshooter.com’s .308 Win start length (and we ended where Rifleshooter’s .308 started — at 28″). Velocity loss can be more extreme with shorter barrel lengths (and bigger cartridges). Powder burn rates can also make a difference.

You Still Need Hearing Protection Even When Using Suppressors

suppressor silencer moderator facts fiction sound levels noise decibles dB
Silencer-equipped AR photo courtesy The Silencer Shop.

OK, you’ve paid the tax stamp and acquired your new suppressor (aka “silencer” or “moderator”). Do you still need to wear earplugs or muffs? Absolutely. Even with that expensive new “can”, your rifle could be generating over 140 decibels (dB) of noise — about the same as as an unmuffled 9mm pistol shot. That’s loud enough to create permanent hearing loss with repeated exposure.

Firearms Are Loud: 140 dB to 175 dB

Audiology group ASHA explains: “Exposure to noise greater than 140 dB can permanently damage hearing. Almost all firearms create noise that is over the 140-dB level. A small .22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss. Also, adding muzzle brakes or other modifications can make the firearm louder. People who do not wear hearing protection while shooting can suffer a severe hearing loss with as little as one shot[.] Audiologists see this often, especially during hunting season when hunters and bystanders may be exposed to rapid fire from big-bore rifles, shotguns, or pistols.” Source: ASHA, Recreational Firearm Noise Exposure.

suppressor silencer moderator facts fiction sound levels noise decibles dB

Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”

Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.

The Myth of the “Quiet” .22 LR
The NRA Blog notes that “many rimfire shooters, particularly those using the beloved .22 Long Rifle cartridge, argue that the small .22 LR caliber doesn’t produce enough sound to damage your hearing”. So, is that really true. or is it a myth?

In fact, a .22 LR can be much louder than you think — a .22 LR pistol can produce sound levels of 134 dB. That’s well above the normal human pain threshhold.

Sound Levels for Common Noises:

9mm Luger pistol: 160 dB

Jet aircraft engine (near): 140 dB

.22 LR pistol: 134 dB

Normal human pain threshold: 120 dB

Noisy Nightclub: 110 db

Riding Motorcycle at 65 mph: 103 db

Power Lawnmower: 95 dB

Hearing damage possible: 85 dB (sustained for 8+ hours)

Ringing Telephone: 80 dB

Normal conversation: 60 dB


The Risk of Hearing Loss
Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. As the NRA Blog cautions: “You may not even realize you’re harming your hearing. Hearing loss occurs gradually, and can go effectively unnoticed until symptoms become severe. By then, the damage is done.”

Nobody wants to go deaf. But we often see shooters without effective hearing protection when they are walking around a few yards behind the firing line. That’s bad — even if you are away from the firing line, gunshot noises can damage your hearing. You MUST use effective hearing protection every time you go to the range. Good foam earplugs costs mere pennies but they can prevent deafness in your later years. Many folks also wear muffs over plugs.

First Unregistered Suppressor Purchase in 92 Years in USA

texas suppressor silencer sale ATF NFA jensen silencer shop firearms policy coalitionImage from Report by USCCA.

A Federal District Court in Texas recently ruled that ATF registration is no longer mandatory for purchases of suppressors (silencers) because Federal legislation eliminated the registration fee, effectively negating the need for paperwork. After the ATF declined to appeal the decision, this opened the door for Texas residents to acquire a suppressor without paying fees or filling out ATF paperwork.

suppressor ATF NFA firearms policy coalitionGun Owners of America (GOA), along with lead plaintiff Silencer Shop, made history on August 13, 2026 as GOA members Brandon Herrera and Wes Virdell lawfully acquired suppressors without filling out registration forms of the National Firearms Act of 1934 and without paying fees.

GOA, Silencer Shop, Herrera, and Virdell notified the Department of Justice and the ATF of their intent to complete the transfers without NFA registration. Because the DOJ and ATF did not object, Silencer Shop transferred the unregistered suppressors to Herrera and Virdell in accordance with all other applicable federal and state laws. The transfers took place at Silencer Shop’s storefront in Leander, Texas on August 13th. Rep. Andrew Clyde (GA-09) and GOA Senior V.P. Erich Pratt also attended.

Two consolidated lawsuits — Jensen v. ATF and Silencer Shop Foundation v. ATF — had challenged the NFA’s regulation of now-untaxed suppressors, short-barreled rifles, and short-barreled shotguns.

GOA spearheaded the repeal of a 1934 law regulating suppressors and short-barreled firearms in the One Big Beautiful Bill Act. The passage of this GOA-backed provision in the One Big Beautiful Bill Act paved the way for two lawsuits which culminated in a federal court order currently enjoining ATF enforcement of NFA registration requirements for suppressors and short-barreled firearms, and “any other weapons.”

This marks the first time since the NFA was enacted on June 26, 1934, that Americans lawfully acquired suppressors without federal registration. This was the first unregistered suppressor transfer in 92 years.

USCCA Report on Effect of Lawsuit
Historic First: Suppressor Transfer Completed Without a Form 4

Just after midnight on August 13, the first suppressors in 92 years were lawfully transferred without an ATF Form 4 or NFA registration under the federal court’s injunction.

Who is eligible?

The ruling is not nationwide. The injunction protects the plaintiffs in the case and, where applicable, their current and future members and customers. That includes certain members of plaintiff organizations such as Gun Owners of America (GOA), as well as customers involved in covered transactions with plaintiff businesses, including Silencer Shop.

Eligibility also depends on state law and the specific firearm involved. Some states still require the traditional Form 4 process, and this ruling does not eliminate every federal firearms requirement. Buyers still must comply with applicable Gun Control Act requirements, including the required background-check process. READ MORE.

Why Should You Shop for Ammo Online?
By shopping online for ammo, you can save money, get a wider selection, and get bulk discounts. GunDeals.com explains: “Online purchases [can] save you a lot of money [and can] also save your time… one of the most important advantages is definitively the huge selection.” With online retailers you can quickly compare prices, and you will often get a discount on a large order (300 rounds or more) that is not available in local stores. Note, with some large vendors such as Cabela’s and Sportsman’s Warehouse you can order online then pick up in a local store.

Are There Restrictions on Online Ammo Purchasing?
In most (but not all) U.S. states is it legal to order ammunition online to be shipped to your residence. However, you MUST check your State and local laws and regulations. In some states and/or cities, it is ILLEGAL to purchase ammunition online for shipment across state lines with direct delivery. For example, in California, though there have been legal challenges, all ammo must still be purchased from a licensed ammo dealer/vendor with a state background check (so much for the Second Amendment)*. Likewise Washington DC, and Hawaii do not allow online ammunition purchases. And there are restrictions in New York City. In Alaska there are multiple shipping regulations that impact ammo deliveries from online sales so many vendors do not ship to Alaska.


*In some instances ammo can be purchased online from an out-of-state seller who will then ship to an authorized, in-state California vendor who may transfer the ammo for a fee with background checks as required by CA law.

Learn How Altitude Affects Ballistics — Important for Hunting

altitude ballistics zeiss LRP S5 318-50 FFP scope
Photo shows the ZEISS LRP S5 318-50 first focal plane (FFP) scope.

“A bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.”

A few seasons back a good friend ventured to the high country of Colorado to pursue elk. He recently zeroed his rifle in California, at a range just a few hundred feet Above Mean Sea Level (AMSL). He wondered if the higher altitude in Colorado could alter his ballistics. The answer is a definite yes. However the good news is that free ballistics calculators can help you plot reliable drop charts for various shooting locations, high or low.

Suunto AltimeterThe question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.

Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:

“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps. By contrast, in Raton, NM, located at 6600′ AMSL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.

Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”

As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect. It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet AMSL), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.

Trajectory of Bullet fired at Sea Level

Trajectory of Bullet fired at 20,000 feet

You can do your own experimental calculations using Berger Online Ballistics Calculator (free to use). Here is an extreme example, with two printouts (generated using Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.

To learn more about all aspects of Exterior Ballistics, Hornady has a useful discussion of External Ballistics including the effects of altitude and temperature. There is also an online archive with detailed information from Sierra’s Exterior Ballistics Resource Page. This web archive features multiple sections from the Sierra Manual (4th and 5th Editions), including:

Section 3.0: Exterior Ballistic Effects on Bullet Flight
Section 3.1: Effects of Altitude and Atmospheric Conditions
Section 3.2: Effects of Wind
Section 3.3: Effects of Shooting Uphill or Downhill

Example from Section 3.0: “When a bullet flies through the air, two types of forces act on the bullet to determine its path (trajectory) through the air. The first is gravitational force; the other is aerodynamics. Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag. All the others are very small in comparison when the bullet is spin-stabilized.”

‘Sights, Wind and Mirage’ from Shooting Sports USA Archives

Wind Reading Quadrant High Power

Vand Zande wind readingIn the digital archives of Shooting Sports USA, we’ve found some great features that deserve a second look. A few years back, Shooting Sports USA published Sights, Wind and Mirage, an outstanding article that explains how to judge wind speed/direction and adjust your sights accordingly. Authored by highly respected shooter Ernest (Ernie) Vande Zande, this article is a definite “must-read” for all competitive rifle shooters — even those who shoot with a scope rather than irons. Vande Zande’s discussion of mirage alone makes the article well worth reading. Highly recommended.

Q & A: TOP TEN Questions about Suppressors Answered HERE »

suppressor silencer moderator facts fiction sound levels noise decibel dBYou’d like to protect your hearing, and maybe you’re a little curious about how your rifle might shoot suppressed. So you’re thinking of buying a suppressor (aka “can”, “moderator”, “silencer”). The good news is that suppressor ownership is now legal in 42 of the 50 American states — that’s 84%! And 41 states allow their use for hunting. So for most American adults, getting a suppressor is legal, provided the owner passes required background checks. But you can’t just get one off the shelf at Walmart. Acquiring a suppressor still requires filling out ATF paperwork. Plus there is typically a pretty long wait. But, thankfully, you no longer have to pay for a $200 Federal Tax Stamp (thanks to recent Federal legislation).

States Where Suppressors Are Allowed
Currently, these 42 states allow private ownership of suppressors/silencers: AL, AK, AZ, AR, CO, CT, FL, GA, ID, IN, IA, KS, KY, LA, ME, MD, MI, MN, MS, MO, MT, NE, NV, NH, NM, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY.

Note: Even if you live in one of the states listed, you should still verify that owning a suppressor is legal in your area. Some states may have municipal- or county-based restrictions.

States Where Suppressor Ownership is Prohibited
Unfortunately, there are still eight (8) States that forbid private ownership of suppressors. The eight No-Go States are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island. In these eight states, private ownership of suppressors (aka “silencers”) is forbidden. Hopefully some of those eight hold-out states will change their laws in the months ahead.

How to Acquire a Suppressor/Silencer

As of January 1, 2026, the federal transfer and manufacturing tax for silencers, short-barreled rifles, and short-barreled shotguns was reduced to $0. While the previous $200 ATF fee is gone, all the underlying regulatory requirements remain fully active.

Still Required When Buying a Suppressor:
— Paperwork: You must still submit an ATF eForm or Form 4 through a licensed dealer.
— Background Check: ATF background check and approval are mandatory before taking possession.
— Identification: Fingerprints and passport-style photos must still be provided with your application.

Looking Inside a Suppressor in Action
Popular YouTube Channel Smarter Every Day recently released a cool video featuring rifle suppressors with see-through acrylic sleeves. The team filmed shots through the suppressors using ultra-high-speed (110,000 frame per second) cameras. When played back in super-slow-motion, you can see the flame propagate through the suppressor and the bullet move through each baffle before it exists the muzzle. Watch the results in the video below — it’s mesmerizing:

Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”

Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.
