Editor’s NOTE: The key to keeping an AR running reliably is proper lubrication (in the RIGHT places), and regular cleaning of the bolt carrier and bolt, including ejector recess and extractor recess. The majority of non-functioning ARs we’ve seen had gunk, lube, carbon, and brass shavings in those recesses.

Bonus Video — AR15 Maintenance with Jerry Miculek
In this helpful video, legendary shooting Jerry Miculek explains how he cleans and maintains his AR-platform rifles. Miculek shoots ARs in three-gun competitions.
“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.
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.”
Gunsmith/stockmaker Doan Trevor created a lovely, one-of-a-kind silhouette stock for an Anschutz rimfire action. Built as a true custom design, this stock combines ideal standing position ergonomics with light weight — the entire stock weighs a mere two pounds. This project really showcases Doan’s remarkable skills with wood. Read the full story about this project (with more photos) at DoanTrever.com.
Doan explains his design process: “A customer came to me wanting to know if I could build a silhouette stock that was 2 pounds or less. I used the Koa wood because it is a lower specific gravity than Walnut (which makes it lighter) and stronger. I was still able to use pillar bedding and keep the weight down. The fore-end could be shortened to reduce the weight even more.
Since the drops on a silhouette rifle are different than a prone rifle, I kept the pistol grip from the prone rifle which is comfortable and tried to come up with a higher cheek piece and more drop to the buttplate. All of this required lots of hand carving.”
Whidden Gunworks makes great sizing and seating dies. The Whidden full-length sizing die with neck bushing is very popular because it allows you to “tune” the neck tension by using different bushings, with larger or smaller inside diameters. In this video, John Whidden explains how to choose a the right bushing size for use with your neck-sizing and full-length sizing bushing dies.
For most applications, John suggest starting with the caliper-measured outside diameter of a loaded cartridge (with your choice of bullet), and then SUBTRACT about three thousandths. For example, if your loaded round mics at .333, then you would want to start with a 0.330 neck bushing. John notes, however, that you may want to experiment with bushings, going down a thousandth and up a thousandth. With thin In addition, as your brass ages and the necks harden, you may want to change your bushing size.
Quick Tip: Try Flipping Your Bushings
You may also want to experiment with “flipping” your neck bushings to alternate the side that first contacts the neck of the case. (One side of the bushing is usually marked with the size, while the other side is unmarked.) So try “number side up” as well as “number side down”.
Some folks believe that one side of the bushing may allow a smoother entry, and that this can enhance concentricity. Other people think they can get very slightly more or less neck tension depending on how the bushing is oriented. This is a subtle effect, but it costs nothing to experiment.
If one bushing orientation proves better you can mark the “up” side with nail polish so that you can always orient the bushing optimally. NOTE: We have confirmed that some bushings are actually made with a slight taper. In addition, bushings may get distorted slightly when the brand name and size is stamped. Therefore there IS a reason to try both orientations.
Lyman’s popular Case Trim Xpress is an affordable, variable-speed case trimmer with a razor-sharp CARBIDE CUTTER. The Case Trim Xpress can quickly and accurately trim brass at a rate of approximately 15 cases a minute. The unit has its own power source — a strong variable-speed motor. Using the 10 provided bushings, the unit indexes off the case shoulder — that’s simple, fast and reliable. Plus a precision trim adjustment wheel allows case lengths to be easily “dialed in” to 0.001″ increments. To trim your brass, simply push the case against the carbide cutter until the shoulder stops on the bushing (with precise case OAL set by the wheel). The Case Trim Xpress comes with 10 bushings that fit the most popular bottleneck rifle cartridges, so no pilots are needed. This is available now for $142.03 on Amazon.
Review by F-Class John
Case trimming can be one of the most boring and tedious steps in the reloading processes. This is largely because of outdated tools that either require manual turning, clunky pilot systems, or difficult adjustments. In order to overcome these obstacles, you might have to spend $500 for some premium systems. But Lyman’s bright orange Case Trim Xpress delivers premium trimming performance at an affordable price. Available for around $145, this trimmer offers an easily-adjustable cutting head plus a smart, shoulder-indexing bushing system to improve consistency and speed up the trimming process.

The Lyman Case Trim Xpress comes with the main trimming unit, power cord, and 10 bushings in a storage case. These 10 orange bushings let you trim more than 50 popular cartridge types (yes including the 6mmBR, 6.5 Creedmoor, and .308 Win of course). Set-up was simple and straight-forward. Install the bushing you need, turn the unit on and slowly push a piece of brass towards the cutting head. Once the brass is fully depressed, you can start adjusting the dial one click at a time until the case makes contact. Then you start making progressive adjustments and trim until you reach your desired length. The process is so simple that it’ll leave you wondering how you ever used anything else.

Vertical stringing is a common problem that all precision shooters will face sooner or later. In addition to ammo inconsistencies, many other factors can cause vertical stringing. Accordingly, it’s important that you analyze your gun handling and bench set-up systematically.
EDITOR: Folks, READ THIS ARTICLE! You WILL benefit. There are some VERY important insights here. You’ll learn ways to set up your gun better, and check for various technical issues. That can save you time at the range and save you money spent on expensive bullets and powder.
In this article, Hall of Fame benchrest Shooter Speedy Gonzalez explains how to eliminate mechanical and gun-handling problems that cause vertical spread in your groups. Speedy’s article addresses the many human and the hardware factors that can cause vertical.
Speedy Gonzalez, noted shooter, gunsmith and member of the Benchrest Hall of Fame, offers these pearls of wisdom to help you eliminate vertical in your shot strings. Remember that vertical can result from myriad gear issues and gun-handling mistakes. Try to isolate one item at a time as you work to improve your groups.
BAGS and REST–VERY IMPORTANT
• Front Rest Wobble — You will get vertical if the top section of the front rest is loose. Unfortunately, a lot of rests have movement even when you tighten them as much as you can. This can cause unexplained shots.
• Rifle Angle — If the gun is not level, but rather angles down at muzzle end, the rifle will recoil up at butt-end, causing vertical. You may need to try different rear bags to get the set-up right.
• Front Bag Tension–Vertical can happen if the front sand bag grips the fore-arm too tightly. If, when you pull the rifle back by hand, the fore-arm feels like it is stuck in the bag, then the front bag’s grip is too tight. Your rifle should move in evenly and smoothly in the sand bags, not jerk or chatter when you pull the gun back by hand.
• Sandbag Fill — A front sandbag that is too hard can induce vertical. Personally, I’ve have never had a rifle that will shoot consistently with a rock-hard front sandbag. It always causes vertical or other unexplained shots.
• Bag Ears — If the channel between the Rear Bag’s ears is not in line with the barrel, but is twisted left or right, this can affect recoil and vertical consistency. And take note — if the bag is off-axis quite a bit, you can also get horizontal stringing.
• Reliability — ALL your bench equipment must work flawlessly. If it doesn’t, get it fixed or get rid of it. We need all our attention on wind flags.
GUN HANDLING and BENCH TECHNIQUE
• Be Consistent — You can get vertical if your bench technique is not the same every shot. One common problem is putting your shoulder against the stock for one shot and not the next.
• Free Recoil — Free recoil shooters should be sure their rifle hits their shoulder squarely on recoil, not on the edge of their shoulder or the side of their arm.
• Head Position — Learn to keep your head down and follow-through after each shot. Stay relaxed and hold your position after breaking the shot.
• Eyes — Learn to shoot with both eyes open so you can see more of the conditions.
• Last Shot Laziness — If the 5th shot is a regular problem, you may be guilty of what I call “wishing the last shot in”. This is a very common mistake. We just aim, pull the trigger, and do not worry about the wind flags. Note that in the photo above, the 5th shot was the highest in the group–probably because of fatigue or lack of concentration.
• Last Shot Low — I hear a lot of discussion about low shots in a group and apparently this occurs a lot on the 5th shot. If your 5th shot that goes out most of the time, you can bet you are doing something at the bench.
• Seating — When possible, bring your own stool so that you can sit comfortably, at a consistent height, every time you shoot.
LOAD TUNING
• Find the Sweet Spot — A load that is too light or too heavy can cause vertical problems. When you’ve tuned the load right, you should see a reduction in vertical. Even 0.1 grain may make a difference, as will small changes in seating depth.
• Primers — If you’re getting vertical, and everything else looks fine, try another brand of primers. And remove the carbon from the primer pockets so the primers seat uniformly every time.
• Case Prep — When you chamfer the inside of your case necks make sure they are smooth enough that they don’t peel jacket material off when you seat the bullet. Bullets with J4 Jackets (like Bergers) and Lapua Scenar bullets seem more prone to jacket scratching or tearing than Sierra bullets.
• Shell Holders — Keep shell holders clean, in both your press and priming tool. I have seen so much dirt/crud in shell holders that the cases end up get sized crooked because the rim is not square to the die.
• Water in Cases — I see people walking around with case necks turned up in the loading block. A lot of the time there is condensation dropping from the roof of your loading area. If one drop of water gets in a case you are in trouble. How many times have you had a bad low shot when it has been raining and you have been walking around with your cases turned up in your block?
MECHANICAL and HARDWARE ISSUES
• Barrel Weight — A lot of rifles are muzzle-heavy. Some rifles have too heavy a barrel and this causes vertical, especially when shooting free recoil. Basically the gun wants to tip forward. The remedy is to trim or flute the barrel, or add weight in the rear (if you can stay within weight limits).
• Unbalanced Rifle — If the rifle is not balanced, it does not recoil straight, and it will jump in the bags. If the rifle is built properly this will not happen. Clay Spencer calls this “recoil balancing”, and he uses dual scales (front and rear) to ensure the rifle recoils properly.
• Firing Pin — A number of firing-pin issues can cause vertical. First, a firing pin spring that is either too weak or too strong will induce vertical problems. If you think this is the problem change springs and see what happens. Second, a firing pin that is not seated correctly in the bolt (in the cocked position) will cause poor ignition. Take the bolt out of rifle and look in the firing pin hole. If you cannot see the entire end of firing pin it has come out of the hole. Lastly, a firing pin dragging in bolt or shroud can cause vertical. Listen to the sound when you dry fire. If you don’t hear the same sound each shot, something is wrong.
• Trigger — A trigger sear with excessive spring load can cause problems. To diagnose, with an UNLOADED gun, hold the trigger in firing position and push down on sear with your thumb. If it is hard to push down, this will cause vertical problems.
• Stock Flex — Some stocks are very flexible. This can cause vertical. There are ways to stiffen stocks, but sometimes replacement is the best answer.
SCOPE ISSUES
• Lock Rings — This year alone I have seen nine lock rings on scopes that are not tight. Guess what that does to your group? Make sure yours are tight.
• Big Tubes Need Tension — We’ve observed that some 30mm scope rings are not getting tight enough, and scopes are slipping in the rings under recoil. This will cause point of aim movement.
• Windage Bases — If you’re using a conventional-style single dovetail with rear windage adjustment, make sure both sides of the windage screws are tight. This can induce both windage AND vertical issues since the rear ring is held down by the windage tension.
AWARENESS of CONDITIONS and READING WIND
• Basic Wind-Reading Rule–If you do not know how to read wind flags or are very inexperienced, try to shoot your group with the flags all going in one direction.
• Rate of Fire — The longer you wait between shots when a condition is changing, the more the condition change will affect your shots.
• Look Far and Wide — Learn to look at the whole field of flags, not just the row in front of you. Many times a change quite a ways out will cause shot to go out of your group well before that change shows up in front of your bench.
• Don’t Fear the Wind — When you realize that the wind is your friend you will become a much better benchrest shooter. By this I mean that wind skills can separate you from other shooters who have equally good equipment. To learn how to read the wind, you must practice in challenging winds, not only in good conditions.
• Watch Wind Direction AND Velocity — Pay attention to angle changes on flags. Even though you see the same windspeed indicators, angle changes make a big difference in your groups.
• Watch While You Wait — Between courses of fire, whenever possible, watch conditions on the range. That way you will be aware of any changes in conditions since your last group and you will be mentally prepared for the new condition.
SPECIAL ADVICE for HUNTING RIFLES
• Clean That Barrel — Most hunting rifle barrels do not get cleaned enough. If you keep barrel clean it will shoot better for you. You should clean your barrel well after every 10 to 12 shots. If you’re lazy, just use Wipe-Out.
• First Shot Inconsistency — Most hunting rifles will not put the first shot (after cleaning) with the subsequent shots. So, after cleaning, if you have a rifle that tosses that first shot high or wide, then shoot one fouling shot before going hunting or before you shoot for group.
• Barrel Heat — Thin-contour “sporter” barrels WILL change point of impact as they heat up. When testing loads for your hunting rifle, take your time and don’t let the barrel get hot on you.
At the CMP’s 2024 National Trophy Pistol Matches, John Bickar of Menlo Park, CA, became only the third competitor in history to earn back-to-back wins in the President’s Pistol Match. John captured his second straight title shooting a 1911 pistol used by his mother, who passed in 2003. After a two-decade long hiatus, Bickar returned to the National Matches in 2023, using his mom’s cherished 1911 pistol. He won the President’s Match in 2023 and now has won a second year in a row with his 2024 victory.
John Bickar won his second consecutive President’s Pistol Match at the 2024 National Matches.
As Bickar packed his gear and waited for others to finish the President’s Match, the USAMU’s SSG Christopher Hudock told John, “That’s the highest score I’ve seen so far.” Bickar then thought: “I might’ve won this again.” Indeed he had won again, and was proud to do it with his mother’s 1911 pistol. “Glad to carry on the tradition,” Bickar said.
The President’s Pistol Match, a staple of the century-old National Matches since 1981, had 414 competitors this year. Bickar fired an overall score of 384-17X over the day — just one point above the second and third place finishers. John noted that the conditions on the day of the President’s Match were nearly ideal.
John Learned Pistol Marksmanship from his Mother and Father
Originally from Canton, Ohio, John competed at the National Matches as a junior. He comes from a line of pistol enthusiasts – with his mom, Judy, a competitor until her passing in 2003, and his dad, John, the president of the Canton McKinley Rifle and Pistol Club for 17 years before his passing in 1994.
John, with his parents’ guidance, earned his Distinguished Pistol Badge in 1993 at the age of 16 — the youngest at the time – and went on to compete in college as well as internationally attending World Championships and Pan American Games. He also trained at the Olympic Training Center in Colorado. He earned his Distinguished International Badge in 2001 and his Distinguished Rifleman Badge in 2018.
Other Notable Performances at the National Trophy Pistol Matches
Finding second behind Bickar was 1LT Lisa Emmert Traciak of Colorado Springs, who claimed the High Woman honor in the President’s Pistol event. She went on to also earn the National Woman’s Trophy as the top scoring woman in the National Trophy Individual Match (NTI), garnering a score of 280-14X, and the Rose Krelstein Trophy as the highest scoring woman in the President’s/NTI Aggregate.
Jonathan Shue of Liberty, NC, was the top overall competitor of the National Trophy Individual (NTI) event with a score of 293-15X. It was Shue’s second time earning his name on the General Custer Trophy, having previously won back in 2019. He also claimed the High Civilian title with his win and took the Anheuser Busch Trophy as the leading competitor in the NTI/NTT Individual Aggregate, with a score of 584-24X. Shue is the current national record holder in the Aggregate event.
What’s a “Wallet Group”? It’s a singularly spectacular proof target that entitles its bearer to bragging rights. The wallet group may or may not have been shot in competition, and, by definition, it may not be repeatable. But it exists as incontrovertible proof that, at least once, the stars aligned, and the wind gods smiled on the shooter.
Five Shots in 0.178 MOA at 1000 Yards
A few years ago, Forum member and F-Class shooter Gary Wood was testing his 6.5-284 rifle at the 1000-yard range in Coalinga, California, getting ready for an upcoming long range match. In practice, Gary nailed a witnessed 1.859″ five-shot group, with four of the five shots well under an inch. Use this as proof to win those club-house arguments about whether it is possible to shoot “in the ones” at 1000 yards. Gary’s group worked out to 0.178 MOA!
Gary reports: “I was load testing with 5-shot groups. Each group was shot on a new F-Class center and pulled by Ret. Master Chief Jerry Pullens and spotted by an other long-range shooter. The second 5-shot load group looked really small … by our reckoning four out of five shots measured under an inch. I was amazed. What’s more, when I shot the group, the 4th shot blew the spindle out of the 3rd shot. My spotter saw that in his scope and Jerry Pullens told me about it afterwards”.
As measured with the OnTarget Software, using a scan of the target, Gary plotted the group size at 1.859″ total for five shots, or 0.178 MOA. Gary noted: “I had everyone sign the target which I saved and photographed.” Yes, Gary, this may be the wallet group to end all wallet groups. You should have that target framed.
Gary’s Load and 6.5-284 Rifle Specs
Gary was running a stout load of Hodgdon H4350 and CCI BR-2 primers, pushing moly-coated 142gr Sierra MKs, in Lapua 6.5-284 brass. The rifle features an F-Class, single-shot Surgeon action with a Bartlein 5R barrel chambered with a no-turn neck. Gary says “The barrel only has 70 rounds through it… yep, I think it will shoot.” Gary did all of the gunsmithing and barrel work himself.
Did Gary have any special reloading tricks? Apparently not: “Other than weighing the cases and the powder very carefully, there really were no magical reloading secrets used. The Sierra 142s were moly-coated straight from the box of 500, but they were not weighed or checked for bearing surface. The powder was dropped with a RCBS ChargeMaster then checked with an Acculab scale (to under a tenth). The Lapua cases were not neck-turned, but I did weight-sort them. The five cases for the small group weighed: 195.05, 195.03, 195.03, 195.03, 195.01.”

AR Set-Up and Maintenance
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.

If, when you pull the rifle back by hand, the fore-arm feels like it is stuck in the bag, then the front bag’s grip is too tight. Your rifle should move in evenly and smoothly in the sand bags, not jerk or chatter when you pull the gun back by hand.
