Mental Preparation for Shooting Matches
Advice from Emil Praslick
Along with these books we offer some smart advice from Emil Praslick III, former USAMU coach. Considered one of the best wind readers on the planet, Praslick also was known for his ability to help his shooters master the “mental game”. Here is an article from the CMP Archives in which Praslick explains how to focus your mind to achieve greater success.
Thinking Your Way to Success by Emil Praslick
Why does it seem that the same small group of shooters wins the majority of the matches? What is the difference among shooters who are technically equal? Confidence. A confident shooter is free to execute his shots without the fear of failure, i.e. shooting a poor shot.
Negative thoughts (can’t, won’t be able to, etc.) will destroy a skilled performance. The mind’s focus will not be on executing the task, but on projecting fear and self-doubt. Fear is the enemy, confidence is the cure. How does a shooter on the eve of an important match … attain the confidence needed to perform up to his potential? A pre-competition mental plan can assist in acquiring that positive mental state. The plan can be broken down into a few phases.
Build a feeling of preparedness. Developing and executing a plan to organize your equipment and pre-match routine will aid you in feeling prepared on match day.
Avoid negative and stressful thoughts. Focusing on “winning” the match or shooting for a specific score (like making the “cut” or making the President’s 100) can cause undue stress. Good shooters focus on aspects that are within their control: their sight picture, their sight alignment, their position. Each shot should be treated as an individual event.
Train stage-specific tasks during your practice sessions. Instead of shooting matches or practice matches only, include some drills that focus on your problem areas. Training in this manner will assist your level of confidence.
As part of your pre-match routine, imagine yourself shooting perfect shots. Visualize getting into the perfect position, acquiring a perfect sight picture, and perfect trigger control.
Be prepared to have your mind blown by Max Michel. This guy is FAST. In this video he puts 18 shots on three targets with two (2) reloads, in a total of 4.79 seconds. That’s right, drawing from holster, he sends 18 rounds in under five seconds, with two mag changes in the process. That works out to a rate of fire of 225 rounds per minute. Consider this — Max shoots faster than a 19th-century Gatling Gun (which had a rate of fire of roughly 200 rounds per minute). And Max is accurate as well as speedy — 16 of Max’s 18 shots were in the targets’ A-Zones, with the other two just barely outside.

At age 39, Max Michel is a legend within the world of competitive shooting. A four-time World Speed Shooting Champion, six-time USPSA National Champion, and three-time US National Steel Champion, Max is a dominant force in pistol shooting sports. Born and raised in New Orleans, Louisiana, Max began shooting when he was just five years old. In 1999 Max joined the USAMU’s Action Pistol Team and served in the U.S. Army for 10 years as an Army shooter and trainer. Today, Max is recognized worldwide as a top-tier athlete and instructor.
Back in 2015, the firearms collection of famed gun writer Elmer Keith went to auction. The Keith Estate auction drew interest from around the globe, and bidding was strong. When the dust settled, and all the individual lots were totaled, Keith’s remarkable collection sold to various bidders for $1,905,458!
High-priced highlights from the auction are shown below. NOTE: You can see more than 60 other Elmer Keith firearms, along with a list of final auction prices. The Guns & Ammo website has a detailed, illustrated report on the Elmer Keith auction with dozens of high-quality photos.
Elmer Keith was an American rancher, firearms enthusiast, and author. Keith was instrumental in the development of the first magnum revolver cartridge, the .357 Magnum, as well as the later .44 Magnum and .41 Magnum cartridges, credited by Roy G. Jinks as “the father of big bore handgunning.” These videos recount Keith’s personal history and his influence on the design of modern Magnum cartridges.
Lot 1038: Colonel Jim Corbett’s .450/.400 “Tiger Rifle” (Sold for $264,500.00)

When Annealing Made Perfect (AMP), a New Zealand-based company, first unveiled its original induction annealing machine at SHOT Show 2015, it was big news in the reloading world. This was a real breakthrough — an induction annealer running on electricity that was fully programmable. No more flames to fuss with. The advent of the AMP annealer was a true “game-changer” for the shooting enthusiasts who reloaded their ammo.
The AMP system is based on smart science and modern technology. Right from the start, AMP invested in advanced lab equipment (such as gear for Micro-Vickers hardness testing). AMP also worked with independent outside metallurgical laboratories. And AMP invited shooters from around the world to send in sample cartridge cases. AMP accumulated a huge archive of cartridges from .17 Hornet to an array of .50 BMG wildcats and everything in-between. AMP’s archive includes multiple brands and even different lot numbers of the same cartridge. AMP now offers the most highly developed and precise consumer annealing system on the planet. That is because of the amazing amount of R&D behind the product, plus the use of advanced technologies.
Annealing Under the Microscope — Informative Articles
Alex and Matt Findlay have produced a series of articles called “Annealing Under the Microscope”. The first of these was released in July 2017. Part 1 was a general explanation of annealing, and busted a number of myths. It examined the repeatability of annealing over multiple reloads, and conducted a series of tensile bullet pull tests.
Annealing Different Brands of Brass
Part 2 of Annealing Under the Microscope covered an important topic — annealing for different brands of brass. This article examines the reasons why different brands of the same cartridge can require different annealing settings. The article also reveals that lot to lot variations of the same brand of brass can make a big difference.
AZTEC Annealing System — AMP Annealers become Smart Machines
In late 2017, Alex and Matt started the development of their revolutionary AZTEC system, which in effect transformed AMP annealers into SMART annealers. It meant that individual customers could analyse their own cases with laboratory grade accuracy without the need to send samples to the AMP lab for calibration.
Part 3 of Annealing Under the Microscope was released in July 2018 after nearly 12 months of R&D on AZTEC. It focused on how to best utilize this new self-calibration capability. It also highlighted the difference between several “premium” brands of brass compared to cheaper alternatives.
Benefits of Precision Annealing — Accuracy and Repeatability
Part 4 of the series was released in September 2019. It focused on the true benefits of accurate annealing, and the arguments for annealing every reload. The study identified sizing accuracy and repeatability as the key factor. This article also revealed the first prototype of AMP’s new auto bullet seater with seating pressure data capture.
Proof on the Target — Down-Range Benefits of Annealing
In Part 5 of the series, AMP’s experts focus on the real world, down-range benefits of annealing, turned out to be a much more complex process than AMP initially planned. Accordingly, Part 5 was conducted in three stages, with three detailed write-ups.
The Part 5, Stage 1 paper examined sizing accuracy of annealed vs un-annealed cases, taking two sets of three identical Peterson Cartridge .308 Winchester cases through twenty (20) reloading cycles. For every cycle, cases were measured both fire-formed and as re-sized. With each cycle the cases were measured for case length, shoulder bump, neck OD, and head OD.
Field Testing in Tennessee — Proof on Target
The Part 5, Stage 2 article covered detailed ballistic testing using multiple rifles, cartridges, and shooters at the Strategic Edge range in Tennessee.
The Tennessee testing sessions accumulated a wealth of data on velocity spreads and group sizes right out to 1,000 yards. The evidence showed a clear advantage for annealed brass, both for average group size and average Extreme Spread for the groups shot with AMP-annealed cases.
Underground Testing with Lou Murdica
Lastly, AMP’s Part 5, Stage 3 paper featured testing by Lou Murdica at an underground range in California. We have previously shown a video of Lou shooting one case, then reloading it and shooting the same case into the same hole at 100 yards.
This time he repeated the feat, shooting one un-annealed case twenty times into the one hole. Then Lou produced another even smaller 20-shot group, shot with a case which he annealed before every shot.
Enjoy These Technical Articles from AMP Annealing
Collectively AMP’s “Annealing Under the Microscope” series represents a remarkable body of outstanding work. Whether you anneal your cartridge brass now, or just want to learn more about the benefits of annealing, we recommend you take a look at this series of informative articles.
We support Hunters for the Hungry, a program that feeds needy families in the USA. Hunters for the Hungry (HFH) is a nationwide program that gives back to communities by supplying meals throughout the country. The NRA works closely with state agencies that supervise meat donations. Since the program’s inception, Hunters for the Hungry has brought millions of pounds of game meat to homeless shelters, soup kitchens, and food banks across the United States. This program has been in place for 27 years. In recent years, HFH affiliates donated 2.1 million pounds of meat on average, supplying over 10 million meals.
Hunt and Help Others
Many American hunters are able to harvest more than they can eat or share with friends and family. Through Hunters for the Hungry you can help share your bounty with those in need. All donated game must be field dressed and legally harvested. Note that each state has different rules and regulations for donations, please check with your local drop off location prior to donating.
Big Horn Armory Gives 5% of Sales Proceeds to Wyoming Hunters for the Hungry Program
To help support H4H efforts, Big Horn Armory has partnered with the Wyoming Wildlife Federation (WWF) for a special Pay it Forward H4H program. From November 1st through 30th, 2021, five percent (5%) of all net proceeds from sales made from the Big Horn Armory website will be donated to the WWF’s H4H program. This donation will help offset the costs of processing donated game meat, which will be distributed to local food banks, pantries, and other food services within Wyoming.
“Last year we were able to donate $3,000 that was used to process meals for donation to food-insecure families within Wyoming, and this year our goal is higher. We are excited to work with the WWF’s Hunters for the Hungry Program again to help ensure that even more Wyoming residents will get healthy meals,” commented Greg Buchel, president of Big Horn Armory.
Winter is coming soon. For many Americans that means indoor training if they want to maintain their shooting skills. Even if you can shoot outdoors all year long in your location, it makes sense for position shooters to work on their rifle holds. The Mantis systems help with that. These advanced smart devices record and plot the movement of your firearm as you aim and then break the shot. There are systems for both dry-fire and live-fire training, starting at $99.99. Considering the cost of bullets these days, and the difficulty of finding primers, it makes sense to increase your dry-fire training.
Mantis X2 for Dry-Fire, $99.99
Built for dry-fire use only, the Mantis X2 ($99.99) provides real-time, shot-by-shot feedback for both pistol and rifle users. You can track multiple training sessions with data-driven insights, and monitor your progress. This unit has earned high user reviews such as: “As a new gun owner the Mantis X is a game changer for me. I have not been able to get to the range during the lockdowns and being able to practice at home [is great].” And another: “Easy to install[.] The App is free and easy to use.”
The Mantis X2 is a good value. The manufacturer states: “There is nothing at this price point that will give you this level of feedback for dry fire.” There are actually four Mantis models: X2 ($99.99), X3 ($169.99), X7 Shotgun ($199.99) and X10 Elite ($249.99). The X3 adds live fire functionality. MORE INFO HERE.
Mantis X10 Elite– Advanced Training System
The advanced Mantis X10 Elite ($249.99) is 50% lighter and 40% smaller than the original Mantis, with three times the battery life and four times the data transfer rate. This new quick-detach X10 system offers all X2 and X3 functions PLUS recoil analysis and software support for all shooting sports (pistol, rifle, shotgun, archery). Collecting thousands of data points per second, the X10 works with dry fire, live fire, airsoft/CO2, and simulated firearm systems.
Mantis Blackbeard Trigger Reset System for AR-Platform Rifles
If you compete with an AR-platform rifle, you can definitely benefit from the Mantis Blackbeard system, a drop-in Bolt Carrier + Magazine replacement that works with your existing trigger. Using electromechanical wizardry, the $199.00 Blackbeard quickly resets the hammer between each shot, so you can stay in position through multiple practice shots. Installation takes less than a minute — remove the bolt carrier group, drop in the red upper unit, place the red Mantis magazine and you’re good to go. All Blackbeards now support both direct impingement and piston-driven ARs. Guys we know say that a few sessions with this system delivered marked improvement in their service rifle scores.
Mantis X3 for Live-Fire or Dry-Fire, Rifle and Pistol
The Mantis X3 collects thousands of data points per second and analyzes your shooting in real-time. For both pistols and rifles, the X3 works with dry fire and live fire. It will also work with airsoft/CO2/compressed air, and simulated firearm systems. Priced at $169.99, the Mantis X3 mounts to standard universal accessory rails. (No Picatinny rail? Creedmoor Sports sells adapters). The X3 is part of the second generation of Mantis Shooting Performance Systems.
In the face of growing online censorship across many popular social media sites (such as YouTube), Brownells has launched a new online resource to help customers build their own AR-15 rifles at home. Hosted at Brownells.com/HowToBuild, the new web page features step-by-step, interactive videos. Featuring Brownells Gun Tech Caleb Savant, the videos show the AR-15 build process with easy-to-follow directions and expert advice.

4140, 4150, 316, 17-4, 6061, 7075-T6 — What is the significance of these numbers? No, they’re not winning lottery numbers. These are all designations for metals commonly used in firearm and barrel construction. 4140 and 4150 are carbon steels, with 4150 often used in mil-spec AR15 barrels. 316 and 17-4 are grades of stainless steel. 316 is “marine grade” stainless, while 17-4 has 17% chromium and 4% nickel. 17-4 is a harder steel used in barrels and receivers. 6061 and 7075-T6 are aluminum alloys. 6061 is “aircraft grade” aluminum, often used for rings and trigger guards, while 7075-T6 is a much stronger, heat-treated aluminum commonly used in AR15 uppers.
You can learn about all these metals (and more) in the online archives of RifleShooter magazine.
Written by Patrick Sweeney, RifleShooter’s Guide to Gun Metal summarizes the primary types of steel and aluminum used in gun and barrel construction. Sweeney explains the nomenclature used to define metal types, and he outlines the salient properties of various steel and aluminum alloys. This is a useful resource for anyone selecting components or building rifles. We recommend you print out the page, or at least bookmark it.
Metals by the Number
The number system for steel classification came from the auto industry. Sweeney explains: “The Society of Automotive Engineers uses a simple designating system, the four numbers you see bandied about in gun articles. Numbers such as 1060, 4140 or 5150 all designate how much of what [elements are] in them. The first number is what class—carbon, nickel, chromium, and so forth. The next three numbers [list other elements in the alloy]. 4140, also known as ordnance steel, was one of the early high-alloy steels. It has about 1 percent chromium, 0.25 percent molybdenum, 0.4 percent carbon, 1 percent manganese, around 0.2 percent silicon and no more than 0.035 percent phosphorus and no more than 0.04 percent sulphur. That leaves most of it, 94.25 percent, iron.”
Aluminum Alloys
Numbers are also used to differentiate different types of aluminum alloys. Sweeny writes: “Aluminum is used in firearms in two alloys: 7075 and 6061. 6061 is commonly referred to as ‘aircraft aluminum’ and has trace amounts of silicon, copper, manganese, molybdenum and zinc. 7075 is a much stronger alloy and has markedly larger amounts of copper, manganese, chromium and zinc.” 7075 Aluminum has significantly better corrosion resistance, and that’s why it is used for AR receivers. The “T6″ you often see appended to 7075 refers to a heat-treating process.
Aluminum (or “Aluminium” in the UK) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminum is the third most abundant element, and the most abundant metal, in the Earth’s crust. (Wikipedia)
To learn more about the metals used in your firearms’ barrels, rings, receivers, and internal parts, read Sweeney’s article in RifleShooterMag.com. Taking the time to read the article from start to finish will expand your knowledge of metal properties and how metals are chosen by manufacturers and gunsmiths. CLICK to Read Guide to Gun Metal.
