“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.”
It’s hunting season, and we have a friend who wants to go 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.
The 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 JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with 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. To dig deeper, Sierra Bullets has a comprehensive Exterior Ballistics Resource Page with multiple sections from the Sierra Manual (4th and 5th Editions), including:
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.”
Over 22 million carry permits have been issued in the United States according to a recent study. Overall 8.5% of American adults now have carry permits. Along with CCW permit holders, millions of other gun owners may carry defensive pistols in “open carry” states. Carrying a defensive pistol is a big responsibility. That’s why all those who carry handguns for self-protection should definitely practice regularly. For many, pistol practice is an indoor experience. Indoor ranges are most convenient for those who live near urban centers, where the biggest threats to public safety currently exist. This article covers indoor firearms training and the proper procedures you should follow at indoor ranges.
This Video Covers Basic Gun Range Safety Rules and Etiquette
FIVE IMPORTANT SAFETY PROCEDURES for Indoor Ranges
1. Follow the Three Fundamental Rules for Safe Gun Handling
ALWAYS keep the gun pointed in a safe direction. ALWAYS keep your finger off the trigger until ready to shoot. ALWAYS keep the gun unloaded until ready to use.
2. Follow ALL Range Officer Instructions
ROs are the first and final authority on any range and their decisions are generally final. Arguing with a Range Officer may just get you thrown out.
3. Don’t Bother Others or Touch Their Guns
Respect other shooters’ privacy unless a safety issue arises. Do NOT engage other shooters to correct a perceived safety violation unless absolutely necessary – inform the RO instead. NEVER handle or touch another shooter’s firearm without their permission!
4. Know Your Range’s Rules
Review and understand any and all range rules and requirements/expectations. For example, what is the range’s maximum rate of fire? Are you allowed to collect your brass?
5. Know What To Do During a Cease Fire
IMMEDIATELY set down your firearm, pointed downrange, and STEP AWAY from the shooting booth (or bench). Range Officers do not want shooters trying to “secure/unload” their firearms in a cease fire situation — they want the shooters separated from their guns instantly.
Double-Up on Hearing Protection When Shooting Indoors
Howard Leight states that Impact Pro muffs are “designed for handgun and pistol shooters looking for high NRR … for indoor ranges, covered ranges or other extremely loud shooting environments.”
When shooting indoors we recommend quality muffs with earplugs underneath, offering double protection. When inside an enclosed range, with other shooters blasting away right next to you, you really need effective hearing protection. But you also need to hear range commands and be able to communicate. That’s why we recommend electronic muffs with quality plugs underneath. We recommend the NRR 33 Howard Leight Max-1 Plugs. These tapered plugs are comfortable, easy to insert, and have a flared end for better sound seal.
On top of those plugs, run high-quality muffs. For indoor ranges where sound levels can be extremely high, we recommend Howard Leight Impact Pro Muffs. These offer an impressive 30 dB Noise Reduction Rating (NRR) and the effective noise reduction can be improved by 4 decibels or more by running plugs as well.* These muffs are pretty comfortable and offer Headphone Functionality so you can connect to your smartphone, MP3 player, or other audio device. These muffs are a good value, an Amazon’s Choice for $64.97.
* Four decibels may not sound like much, but remember the decibel measurement system is logarithmic, so four decibels is VERY significant. We have discussed the merits of “doubling up” hearing protection with Ph.D. sound engineers. They told us that a combination of muffs and plugs could reduce effective noise levels by up to five decibels compared to plugs alone. In addition, good muffs will block bone conduction sound energy better than plugs alone.
Chris Simmons Wins International Precision Rifle Federation PRS World Championships
Lapua congratulates Team USA’s Chris Simmons on winning the first-ever International Precision Rifle Federation Precision Rimfire World Championships. This highly anticipated match took place August 28 through September 3 at the Piancardato Tiro A Volo range in Collazzone, Italy. Chris was shooting a Vudoo rifle with Lapua X-Act .22 LR rimfire ammunition. Simmons posted an Aggregate score of 165.00 points with a time of 1480.45. The first four finishers were also from the USA. CLICK HERE to see hundreds of photos from the event.
The International Precision Rifle Federation (IPRF) World Championships drew top shooters from 23 nations. The three-day event had competitors tackle a challenging course of fire at different distances, shooting from both supported and unsupported obstacles, with long-range shots, and moving targets, all within tight time constraints.
Simmons, no stranger to the winner’s circle, was part of a two-year selection process to represent the United States at the inaugural IPRF event. Over the past nine months, Simmons took his training to another level, getting up before daylight to hit the range. He also spent many evenings after work shooting 10-12 different positions in a 90-second timeframe, firing hundreds of rounds daily.
Match was conducted in a beautiful hillside location in Collazone, Italy.
After surviving tricky wind conditions and bad wind calls, Simmons found himself in second place prior to going into the last two stages. He then performed great in the final two stages, taking the overall win: “Paul Dallin and I ended up tied and it came down to the fastest aggregate time of all the stages,” commented Simmons. “I won the World Championship by 23 seconds in 2023! Paul is a hell of a shooter and competitors and was tough to beat. Congratulations to him on his second-place finish!”
Top Five Shooters at IPRF Rimfire World Championships:
1. Chris Simmons, USA
2. Paul Dallin, USA
3. Payton Grimes, USA
4. Tyler Orth, USA
5. Radek Novak, Czech Republik
“It was an honor to be able to represent Team USA in the World Precision Rifle Championships in Italy. Thank you to Lapua for supporting both myself and Team USA with quality ammunition,” stated Simmons.

RCBS, a leading manufacturer of reloading equipment and tools, celebrates its 80th anniversary this year, marking eight decades of equipping handloaders with quality, American-made reloading gear. “After 80 years of operation, RCBS is still delivering top quality reloading products backed by world class customer service,” said Justin Smith, product line manager for RCBS. “The brand has never lost the essence that Fred championed back in 1943 and the men and women in Oroville today truly do bleed green. You’ll be hard pressed to find another group who cares more about the quality of products they produce and the consumers who depend on them.”
The RCBS story began in 1943 in the backroom of Fred T. Huntington’s father’s laundry and dry-cleaning business in Oroville, California. A dedicated shooter, Huntington sought to make his own high-quality .22 caliber bullets for shooting local varmints known as rock chucks. He designed and crafted his own “Rock Chuck Bullet Swage” dies, a name later shortened to RCBS.
In the decades following becoming a business, RCBS rapidly grew from a small shop into the nation’s leading maker of reloading equipment. Now using state-of-the-art equipment in large manufacturing facilities, RCBS has stayed near its roots in Oroville.
Product manager and R&D engineer, Steve Koch, has witnessed RCBS’s impressive growth firsthand. He’s been with the company for over 40 years and knows personally how passionate the employees are in Oroville. “Wow, 80 years, a lot has changed. I’m very proud to say that I’ve spent 45 years at this great establishment,” said Koch. “Everyone is extremely proud of what we have here in Oroville. The pride and dedication of the people that produce, assemble and package the finest reloading equipment in the world is the key to our success. Quality is the RCBS motto, and we will continue to ensure we provide our customers with the finest reloading equipment possible.”
In honor of its 80th anniversary, RCBS will soon be introducing a limited-edition Summit single-stage reloading press. This American-made press will feature a special red, white and blue design, and will be limited to only 1,000 pieces. Stay tuned to RCBS social media channels and RCBS.com for more info on this special Summit press release.

Many short-range Benchresters have thought about converting their 6 PPC to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you have a rifle that does double duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).
“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert
Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
Rebate Your 30 BR Rims
To convert a PPC-boltface action to shoot bigger cases you can spend a ton of money to buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.”
At right is the lathe form tool Butch uses to rebate the case rims.
We like Lyman’s Electronic Digital Trigger Pull Gauge, which is faster and more precise than the previous model. The latest Lyman Pull Gauge measures trigger pull weights from 1 ounce to 12 pounds with resolution of 0.1 ounces (2.8 grams). It features an adjustable, 4-position rod which retracts into the gauge body. We think that anyone running match triggers below 2.5 pounds pull weight should have a gauge like this. Among the pull gauges on the market, we think the Lyman unit offers great performance for the price. This gauge has a $69.95 MSRP, but it’s now $54.99 at Midsouth and $56.06 on Amazon.
Features: More Precise Strain Gauge | Improved Grip Shape | Adjustable Rod Lengths
Lyman’s Electronic Digital Trigger Pull Gauge is designed to be the fastest and most accurate trigger pull gauge available. State-of-the-art strain gauge technology allows for repeatable accuracy of 1/10 ounce (2.8 grams). The gauge features a large, easy-to-read LCD display and you can switch from ounces to grams with the push of a button. The gauge can also deliver a pull weight average of the last 10 readings. That’s very helpful, particularly when working with factory triggers that may not be very consistent.
The Lyman Trigger Pull Gauge features a solid, collapsible rod with four locking positions. Being able to adjust length makes it easier to use the gauge with a wide variety of firearms — pistols, rifles, and shotguns. The locking feature prevents the rod from flexing when applying pressure to the trigger. When not in use, the rod conveniently collapses into the gauge body, making the whole unit more compact. The new Trigger Pull Gauge comes in an internally-padded plastic case that can be easily stored in a drawer or on your work bench.
They say that a man can never have too much money or too much time. Darrell Jones would add that a man can never have too many BR-based rifles. Darrell had a fleet of BRs, in 22 BR, 6mm BR, 6.5 BR, 7 BR, and 30 BR. But he was intrigued by the potential of a rifle in the .257 caliber. Could it shoot as well as a 6mm BR? Could it challenge the more popular calibers in the highly competitive 600-yard benchrest game? Through careful research and component selection, Darrell created a 25 BR rifle that proves the viability of the 25 BR as a competition round. Pushing 115gr high-BC Berger bullets at 2837 fps, Darrell’s 25 BR “Peppermint” won first place in its very first match.
The Barely Bigger BR — Exploring the .25 Caliber Option
Rifle Report by Darrell Jones
I decided to build a 25 BR after several weeks of deliberation and ruling out a .257 Ackley Improved. Part of my dilemma was that I wanted to shoot F-Class competition at 600 yards, and I was unsure about the accuracy potential of the 25 BR. However, I currently have several BRs chambered in 22 BR, 6BR, 6.5 BR, 7 BR, and 30 BR and they all shoot exceptionally well at 600 yards. This lead me to believe a 25 BR should deliver fine accuracy, just like its other BR siblings. Why wouldn’t a 25 BR shoot accurately provided that I built it with the right components? The feasibility saga began. I began searching diligently for custom 25-caliber bullets. Unfortunately, there are not many 25-caliber custom bullet makers. I actually found only two custom bulletsmiths who produce the 25s. I did look at Fowlers and then looked at Bergers. Both Jeff Fowler and Berger made 110-grain flat-base bullets when I was looking. [Editor — this 110gr bullet is no longer listed by Berger]. The Berger 110gr FB bullets (.414 ballistic coefficient) shot very well out of my 12-twist 25-06 Ackley. However, I wanted to shoot a heavier bullet if possible. Berger makes a 25-caliber 115gr VLD boat-tail with a high ballistic coefficient. This needs a 10-twist barrel.
Panda Action, McMillan Stock, Weaver T-36
As you can see, I went with a Panda polished action and a weighted McMillan BR stock painted metallic silver with red candy cane stripes thus the name “Peppermint”. This gun actually does double duty now as a 25 BR and 6 PPC switch barrel. When I want to run the gun as a 6 PPC for short range, I simply screw on the PPC barrel, then swap in a bolt (fitting the PPC bolt face) from another Panda action I own. That’s one advantage of owning custom Kelbly actions! Don’t even think about exchanging bolts between factory guns. Kelbly rings and a Weaver T-36 fixed-power scope handle the optical duties while a Jewell trigger set at one ounce takes care of the firing mechanism.
Chambering for the .25 Caliber BR Wildcat
I wanted a chamber that would let me shoot both the 110s and the 115s. I took some time surfing the net looking for rental reamers that had suitable throat dimensions. I found that Elk Ridge Reamer Rentals had a 25 BR pilot reamer available. I called and Elk Ridge faxed me a reamer diagram that indicated it was designed to tight SAMMI specs. I asked how often was the reamer used and was told “not very often”.
I did want a minimum no-turn neck optimized for Lapua brass. The drawing indicated that the reamer would cut a .281″ neck and a throat of 1.0315″. This was very close to ideal, though I did have to turn two thousandths off the necks of Lapua 6BR brass after I necked it up. I resized using a .277″ bushing and the loaded rounds came out to be .279″. Realizing that this was in the ball park, I decided to go with the Elk Ridge Reamer and build a 25 BR that could shoot 110gr or 115gr bullets. Now the question was where to get a match-grade 25-caliber barrel. I called quite a few of the custom barrel-makers, including BlackStar Barrels in Texas (no longer operating). I have had wonderful success with the BlackStar barrel on my 6BR “Chantilly” — it delivered great accuracy and impressive velocities. Since the 25 BR was so similar, I went with another BlackStar. I ordered a 10-twist, 6-groove, 1.250″-diameter straight-contour tube.
After chambering, the barrel finished at 1.245″ diameter and 27.5″ inches with an 11° crown. I actually had the throat lengthened to accept both Berger 110gr and 115gr bullets. The bases of the FB 110-grainers sit flush with the neck-shoulder junction, when they are seated .010″ into the lands. With the longer 115gr VLDs, the bottom of the bearing surface (i.e. start of boat-tail) is just about even with the neck-shoulder junction.
Accurate Load Development
The barrel broke in easily with just 10 shots, using a “shoot one and clean” process. The load I started with was 31.5 grains of Varget with CCI 450 primers. The Berger 110s and Berger 115s had the same Point of Impact (POI) at 100 yards. However, the 115s impacted two inches higher at 600 yards with the same load. That shows the benefits of a higher BC. Pushed by the CCI 450s and 31.5 grains of Varget, the 115-grainers were running about 2837 FPS. I boosted the load up to 32.0 grains but I noticed primer cratering, so I backed off, settling on 31.5 grains for the 115gr Berger VLD.
Peppermint Wins at 600 Yards
For her debut in competition, I took “Peppermint” to our local 600 yard F-class match. Shooting the Berger 115s with 31.5 grains Varget, she won with a perfect score of 200 with 14 Xs. At my club, we use a SR3 target. The X-Ring measures 3″ in diameter and the 10-Ring measures 7″. At the match there were some very good shooters with top-flight custom rifles in accurate calibers such as 6.5-284 and 22 Dasher. I was very fortunate to come out on top, but I give the credit to Peppermint’s good bench manners and outstanding accuracy.
As you can see from the target, “Peppermint” is a very accurate rifle that has proven herself in competition. It takes a good gun to finish “on top” in her very first match. So far, I’m very happy with the project, and more than satisfied with the accuracy of the 25 BR. This is definitely a worthy cartridge for Egg Shoots, 500m varmint matches, and the 600-yard F-Class game.

Comparing the BR-Based Variants
Now that I have several calibers in the BR cartridge family, (22 BR, 6mm BR, 6.5 BR, 7 BR, and a 30 BR), it is my humble opinion that they each have their own place. A varmint hunter’s dream, the 22 BR can push a bullet faster and more accurately than the 22-250. With an 8-Twist barrel, the 22 BR can send an 80gr SMK to 600 yards with extreme accuracy.
The 6 BR can do it all. The 6mm caliber offers a wide variety of quality bullets suitable for any shooting situation. All the major custom barrel makers produce outstanding 6mm barrels in a full range of twists. Moreover, since the 6 BR cartridge is so popular, there is a great store of knowledge about reloading for the 6 BR. It is easy to find a load that will shoot superbly in any bullet weight.
The 25 BR has proved to be easily tuneable, proficient and not fickle. You can obtain extreme accuracy without great effort in load development. The 115gr Berger offers a good high-BC projectile for this caliber, making the 25 BR a viable alternative to the 6 BR. As I’ve shown, it is competitive with a 6 BR in head to head competition.
Compared to the 25 BR, the 6.5 BR has a small edge in ballistics. However, there are not many light bullet choices available, especially from custom makers. The 123gr Lapua Scenar is an excellent bullet with a .547 stated BC, but it may be a bit heavy for the case capacity.
The 7 BR was designed for silhouette shooting, and it excels at that task. The 7 BR can push a 130 grain bullet fast enough to knock over the steel silhouettes at 500 meters with real consistency.
The 30 BR is nothing less than outstanding. The 30 BR is now the dominant cartridge on the benchrest Score-shooting circuit. It is also highly accurate for group shooting at 200 yards and very capable of winning a 600-yard F-Class match. Barrel life of over 6,000 rounds is realistic.
I like all the “flavors” of BR derived from the 6mm BR Norma case. However, if I could only have one BR in my safe, give me my 8-Twist, 6 BR “Chantilly” and I will be a happy camper. The final point I would make is if a cartridge is stamped BR on the case, it will shoot extremely accurately if you can.
Earlier this month, gunmaker GLOCK Inc. presented a $50,000 check to the Civilian Marksmanship Program (CMP) at the CMP Talladega Marksmanship Park in Alabama during the GLOCK Sport Shooting Foundation (GSSF) Annual Match. GLOCK has been a generous sponsor and supporter of the CMP and Talladega Marksmanship Park throughout its existence, dedicating thousands to the organization each year to be used toward programs and initiatives.
The 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.
I did want a minimum no-turn neck optimized for Lapua brass. The drawing indicated that the reamer would cut a .281″ neck and a throat of 1.0315″. This was very close to ideal, though I did have to turn two thousandths off the necks of Lapua 6BR brass after I necked it up. I resized using a .277″ bushing and the loaded rounds came out to be .279″. Realizing that this was in the ball park, I decided to go with the Elk Ridge Reamer and build a 25 BR that could shoot 110gr or 115gr bullets. Now the question was where to get a match-grade 25-caliber barrel. I called quite a few of the custom barrel-makers, including BlackStar Barrels in Texas (no longer operating). I have had wonderful success with the BlackStar barrel on my 6BR “Chantilly” — it delivered great accuracy and impressive velocities. Since the 25 BR was so similar, I went with another BlackStar. I ordered a 10-twist, 6-groove, 1.250″-diameter straight-contour tube.
After chambering, the barrel finished at 1.245″ diameter and 27.5″ inches with an 11° crown. I actually had the throat lengthened to accept both Berger 110gr and 115gr bullets. The bases of the FB 110-grainers sit flush with the neck-shoulder junction, when they are seated .010″ into the lands. With the longer 115gr VLDs, the bottom of the bearing surface (i.e. start of boat-tail) is just about even with the neck-shoulder junction.
