Our friend Anette Wachter, aka “30CalGal”, stars in a smart video from NRAWomen.com. In this episode of Tips & Tactics, Anette talks about the “mental game” in competition. Specifically she explains how to “visualize success”:
I have found that a lot of my success in competition has come through what I call a ‘mental rehearsal’. I actually visualize every stage of the match and I visualize the success of the match and winning the match.
I actually visualize that round going downrange into the target, and the target coming up with a dead-center ‘X’. I visualize this over and over. If you visualize success you will achieve success.
Visualization is a process of mental preparation that is done before you get to the range. Many of the greatest shooting champions have used this technique to get ready for big matches, and to optimize their performance during record fire. If you want to enhance your “mental game” through pre-match visualization, we strongly recommend Lanny Bassham’s book, With Winning in Mind.
As a competitive smallbore 3P shooter, Bassham developed a mental management system. Using this system, Lanny Bassham won 22 world individual and team titles, set four world records, and captured an Olympic Gold Medal in Montreal in 1976. His techniques have been embraced by professional and Olympic athletes in many sports. With Winning in Mind covers a complete system of “mental management” techniques used by Olympians and elite champions.

Life is short. Go Shoot! — Anette Wachter
Along with being a talented competitive shooter, Anette created a popular Gun Blog, 30CalGal.com, and she has written for many gun publications including GunUp Magazine, Shooting Sports USA, Sure Shots Magazine, and Wide Open Spaces. CLICK HERE for a lengthy feature story about Anette’s impressive competition history, created for the Women’s Outdoor News. Among her many notable performances Anette remembered a big win in British Columbia: “My favorite, is of course, winning the BC Rifle Championships in 2011. [I was] the second woman and first US woman to win in its 127 year history.”
.009” Group Record Stood for 40 Years
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.
Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s NBRSA record .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.*
Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.
*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.
About Jerry Miculek… The Man, The Myth, The Legend
The video above begins: “My name is Jerry Miculek. Guns are what I do.” Jerry Miculek is a true legend in the firearms community. Acknowledged as the best wheelgun speed-shooter in history, Jerry is also an accomplished rifle and shotgun shooter with many class victories in 3-Gun competition. He also has been a prolific YouTube Video creator. For this Saturday Showcase, we feature seven notable Jerry Miculek videos. You will find over 500 more interesting videos on the Miculek “Trigger Tribe” YouTube channel Jerry shares with his daughter Lena Miculek.
How to Avoid Common Mistakes with Semi-Auto Rifles and Pistols
In this second video, Jerry explains common mistakes people make when handling and shooting three classic, semi-auto firearm types — the M1 Garand, the SKS carbine, and the M1911 pistol. Jerry shows handling faults that can cause out-of-battery detonation or early primer strikes, or cause jams in the Garand and SKS. Then Jerry explains why you should never release the slide on a M1911 pistol with a round already in the chamber. This is a must-watch video for Garand owners.
Hitting Target at 400 Meters with a Pistol
Could you hit an 18″ x 24″ target at a distance of 400 meters (437 yards)? Sure, you’re thinking, that would be easy with a good rifle fired from the bench or prone position. OK, now think about making that shot, OFF-HAND with a pistol. That’s something entirely different. We doubt many marksman would wager they could hit a plate 400 meters away with a handgun. That’s exactly the challenge legendary shooter Jerry Miculek undertakes in this interesting video. Shooting a Smith & Wesson 9mm M&P pistol with a red-dot optic, Jerry makes the 400m shot look easy, hitting the steel plate with his first shot. This takes good eyes, a solid grip, perfect trigger control (and a bit of luck).
Take-Down and Full Cleaning of AR-15
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. In this video, Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
Ammo Types and Calibers — Jerry Miculek Explains the Basics
In this video, legendary shooter Jerry Miculek talks about popular types of pistol and rifle ammunition and the various bullet options used for plinking, competition, and self-defense. Jerry, one of the greatest pistol shooters on the planet, provides useful insights on cartridge selection and bullet choices. Jerry notes: “There are a TON of different types of ammunition” so he explains the basics. And Jerry answers common questions such as: “What is the difference between ball and hollow-point bullets?” and “What type of gun takes rimmed cartridge versus rimless?”.
Wheelgun Wisdom — How to Avoid Problem with Revolvers
Jerry Miculek has won multiple revolvers championships, and has set amazing records for revolver speed shooting (with reloads). Yes Jerry, “Mr. Revolver”, knows a thing or two about wheelguns. In this video, Jerry explains how you can damage your revolver by using the wrong methods to open and close the cylinder and extract ammo. Jerry shows what NOT to do, and then he very carefully explains the proper procedure to release the cylinder, and swing it out of the frame. In addition, Jerry shows how best to swing a loaded cylinder back into place.
80,000 Philippine M1 Garands in One Place
Back in 2020 Jerry Miculek visited the CMP’s HQ in Alabama. There he looked at the vast inventory of military rifles, including 80,000+ M1 Garands recently received from the Philippines. CMP tech staff showed Jerry some rare Garands that had never been issued. If you’re interested in classic military arms, you should definitely watch Jerry’s video. Gina Johnson, CMP’s general manager, told Guns.com that: “We have roughly 86,000 rifles from the Philippines and roughly 13,000 rifles from Turkey in our possession”.
Along with the 80,000+ Philippines Garands, the CMP received 13,000 from Turkey. The arrival of these 99,000 M1 Garands is great news for rifle collectors. Garands have been in short supply in recent years.
Plan Your Visit: Top 5 Areas to Explore Near Camp Perry Feature based on article by Ashley Dugan, CMP Writer
This summer, many of our readers will visit Camp Perry, Ohio to participate in the historic CMP annual National Matches. There will be smallbore and centerfire rifle matches, along with pistol matches. And this year there will be a number of new mid-range (600-yard) rifle matches. For those competing at Camp Perry this summer, there are many interesting nearby places to visit along the shores of Lake Erie. This article covers some tourism highlights in the area — the Top 5 areas visitors can explore outside of Camp Perry this summer. Many of these tourism attractions are featured in Ohio’s useful Shores and Islands website.
Marblehead and East Harbor State Park
Marblehead is a small village about 18 miles east of Camp Perry. The downtown area offers a strip of quaint shops and restaurants along with an eclectic array of artist galleries and events.

Sandusky and Cedar Point
Just a short drive across the bay, you’ll find Sandusky, which is home to Cedar Point, a large amusement park opened in 1870 that now has over 70 thrill rides, including 18 roller coasters. The park is built within its own peninsula and holds a mile-long sandy beach and water park. Kalahari Resort & Convention Center, located in Sandusky, is Ohio’s largest indoor water park. Buy a day pass to the many pools and water slides. This is the USA’s #1 indoor water park according to USA Today. Other Sandusky amenities include the Sandusky Mall, a Merry-Go-Round Museum, a speakeasy bar, and the Jackson Street Pier with a variety of restaurants to enjoy. Learn more about Sandusky at CityofSandusky.com.
Lake Erie Islands
The Western Basin of Lake Erie, where Camp Perry is located, is home to several unique islands. Just a short ferry ride away, guests may rent golf carts, bikes, or take their own transportation. Such islands include South Bass, home to Put-In-Bay. The island is also home to Heineman Winery, founded in 1888. While at the winery, explore Crystal Cave, one of the largest geodes in the world, and Perry’s Cave, a limestone cavern discovered in 1813. Families may also visit the Perry’s Victory & International Peace Memorial, at 352 feet, one of the tallest monuments in the USA.
Viewable from South Bass is Kelleys Island, another fun destination in Lake Erie. The island offers historic homes, bed & breakfasts, and a State Park where you can camp, sunbathe, swim, or rent kayaks. Next to the beach is the Glacial Grooves, a natural phenomenon created when a massive glacier moved through the area millions of years ago, forming the Great Lakes.

Loading Precision Centerfire Pistol Ammunition
If you want to compete in top competitions like the CMP matches at Camp Perry, you’ll need good ammo. The following USAMU article provides rock-solid reloading advice, explaining how to load accurate, reliable handgun ammo.
The U.S. Army Marksmanship Unit (USAMU) fields pistol teams as well as rifle and shotgun competition squads. Consequently the USAMU’s Reloading Shop loads tens of thousands of pistol rounds every year. In this article, the USAMU’s handgun experts talk about reloading for handguns — with smart tips on how to achieve superior accuracy with 100% reliability. This article, which offers important insights on COAL, primers, crimps and more.
Precision Pistol Reloading — Recommended Methods
Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.
Use Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However, for the “long line” (50 yards), purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.
Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]
Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.
Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically.
The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the prestigious Distinguished Pistol Shot badge.
Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding. Stay safe, and good shooting!

Erich Mietenkorte Wins 2025 Canadian Rifle Silhouette National High Power Championship.
Team Lapua’s Erich Mietenkorte took top honors at the 2025 Canadian High Power Rifle Silhouette National Championships, winning the 240-shot High Power Aggregate with an impressive combined score of 195/240. Held at the Bull River Shooters Association range in Cranbrook, British Columbia, from June 29 to July 5, the national championship featured both Smallbore and High Power rifle disciplines, with competitors engaging steel silhouette targets from the standing offhand position at distances of 200, 300, 385, and 500 meters.
Mietenkorte competed in both High Power categories — Standard Rifle and Hunting Rifle — scoring 99/120 with his 6.5×47 Lapua in the Standard division, and 96/120 with his 6mm BR in the Hunting Rifle division. Mietenkorte’s combined performance earned him first place overall in the High Power aggregate and national titles in both rifle categories.
“Success in this discipline requires absolute confidence in your equipment. When it comes to consistency, reliability, and performance,?Lapua cases and bullets,?Vihtavuori powders, and?Berger bullets?are unmatched,” commented Mietenkorte. “I used Lapua 108gr and 139gr Scenar bullets in my 6.5×47, and Berger 95gr and 115gr bullets in my 6BR, all handloaded with Vihtavuori N140 powder. These components gave me the precision and consistency needed[.]”
What’s next? Mietenkorte will be competing at the U.S. NRA Rifle Silhouette National Championships at the NRA Whittington Center in Raton, NM, July 20-26, 2025.
In addition to his success in the Canadian High Power competition, Mietenkorte finished 4th overall in the Smallbore Standard Rifle category. In the video below Eric demonstrates Smallbore Silhouette marksmanship skills.
Silhouette Champion Shares His Skills
In the video below, silhouette champion Eric Mietenkorte explains proper hold: “Consistency is key! Form a solid stance that is repeatable and allows you to have a natural point of aim. If you don’t come down on target adjust your feet, don’t rotate your body with your torso muscles.”
Erich explains his aiming method: “Pick a spot on the target and shoot for that. Try not to hesitate, if you’re on target, take the shot. It’s easy to get locked up by trying to make a great shot better. Make sure to follow through, keep that trigger pulled back. Don’t forget to have fun!”
Mark and Ryan, co-hosts of the Vortex Nation Podcast, have released an informative video about gun choice for home defense. Mark and Ryan examine the performance of pistols, rifles, and shotguns in home defense scenarios. The podcast looks at the practical side of ballistics, comparing the pros and cons of these three gun types. The hosts assess the effectiveness (and penetration power) of these weapon types via field tests with cardboard silhouette targets, ballistics gel, and drywall. The eye-opening tests show how pistols, rifles, and shotguns perform in terms of accuracy, penetration power, and likely lethality.
At an indoor range, the Vortex team tests these three gun types (rifle, pistol, and shotgun) used for protection of home and family. They run a simulated home defense scenario, aerate some dry wall for science, and hit the ballistics gel to give you the real-world testing and fun you expect with plenty of surprises along the way.

The CMP’s hugely popular Rimfire Sporter event runs Sunday, July 20, 2025 at Camp Perry, Ohio. Prior to the Sunday match, on Saturday, July 19th, the CMP will host the Rimfire Check-In and a CMP Rimfire Clinic.
New Range Location Will Have E-Targets
Unlike past years, the 2025 National Rimfire Sporter match will be held on Camp Perry’s Petrarca Range — equipped with CMP eTargets. This should please the hundreds of Rimfire Sporter competitors. The Petrarca range features more conveniences, such as a covered firing line and adjacent parking. Moreover, the eTargets should improve the experience for competitors. Brian Williams, CMP Highpower Manager, explained: “The matches should run faster, without the need to hang targets and do the scoring.”
E-Targets for Rimfire Sporter Match This Year
For the first time, this summer the CMP will utilize the electronic targets of Petrarca Range for the National Rimfire Sporter Match. Featuring Kongsberg Target System (KTS) technology, the system includes monitors at each firing point.
The eTargets will permit the Rimfire Sporter Match to run more smoothly and efficiently. Competitors won’t have to walk down-range between relays to change targets, and scores will be tracked and recorded instantly. Monitors placed alongside each competitor will instantly show shot placements during the match, while suspended displays above the firing line will allow spectators to follow along with each shot in real time.
Popular Match for Junior and Adult Competitors
The National Rimfire Sporter Match, one of the most well-attended events of the annual National Matches, is open to both adults and juniors of all experience levels. Using .22 caliber rifles at 25 and 50 yards, participants in the match traditionally chose from three separate classes: Open Sight (O), Telescope Sight (T) and Tactical Unlimited (TU). Due to high demand, the CMP has added an “M-class” for 2025 to give competitors the option to use U.S. military rimfire training rifles during competition. Competitors may enter in Single or Double Entry options and then select the rifle class(es) in which they will fire.
Firing is done at 25 and 50 yards in prone, sitting, and standing positions, in slow and rapid-fire modes. For each Class, awards are offered to High Juniors, High Seniors, and High Women as well as Overall Winners.
If there is a single CMP event at Camp Perry every summer that offers the highest level of shooter satisfaction, the most diverse group of competitors, and the lowest cost of entry, that would have to be the annual Rimfire Sporter Match. Shooters range in age from young juniors to seniors in their 70s and 80s. And persons with disabilities can compete as well, with Adaptive Shooting Programs for physically-challenged competitors.
Each year, the Rimfire Sporter Match attracts hundreds of shooters to Camp Perry. National Rimfire Sporter competitors can use affordable sporter rifles with either scopes or iron sights. All you need are a .22 LR rifle, a simple sling, and ammo. Rifles may be manually operated or semi-automatic, in four classes: the standard “O Class” for open-sighted rifles, “T-Class” for telescope-sighted rifles, the “TU Class” for Tactical and unlimited rifles, and the new “M-Class” for Military Rimfire Training Rifles.
Rimfire Sporter Course of Fire
Competitors will complete slow fire prone, rapid fire prone, slow fire sitting or kneeling, rapid fire sitting or kneeling, slow fire standing, and rapid fire standing shot sequences. To learn more about the National Rimfire Sporter Match, CLICK HERE.

Berger Twist-Rate Stability Calculator On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude. This cool tool tells you if your chosen bullet will really stabilize in your barrel.
How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculator is simple. Just enter the bullet DIAMETER (e.g. .264), bullet WEIGHT (in grains), and bullet overall LENGTH (in inches). On its website, Berger conveniently provides this info for all its bullet types. For other brands, we suggest you weigh three examples of your chosen bullet, and also measure the length on three samples. Then use the average weight and length of the three. To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher).
Gyroscopic Stability (SG) and Twist Rate
Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque).
If you have an SG under 1.0, your bullet is predicted not to stabilize. If you have between 1.0 and 1.1 SG, your bullet may or may not stabilize. If you have an SG greater than 1.1, your bullet should stabilize under optimal conditions, but stabilization might not be adequate when temperature, altitude, or other variables are less-than-optimal. That’s why Berger normally recommends at least 1.5 SG to get out of the “Marginal Stability” zone.
In his book Applied Ballistics For Long-Range Shooting (3rd Ed.), Bryan Litz (Berger Ballistician) recommends at least a 1.4 SG rating when selecting a barrel twist for a particular bullet. This gives you a safety margin for shooting under various conditions, such as higher or lower altitudes or temperatures.
