October 19, 2021 NRA publication Shooting Sports USA has thousands of articles online. All are free to read. Many of these stories were written by top competitors, including Olympic and National Champions. Every week, SSUSA articles will be highlighted on the NRA Competitive Shooting page. This page is a great resource and we recommend that you bookmark it. Here are four notable SSUSA articles featured on Facebook this month. Visit SSUSA.org for more current articles and new content every day. This article, which is 1850 words long, provides a detailed explanation of the phenomenon we call mirage. This article will explain how mirage works, how to monitor it, and how mirage can be used to indicate wind direction and velocity. Top competitors use the phrase “Mirage can be your friend” to describe mirage as the most important indicator for wind variables. Sometimes mirage is even more important than wind flags. Desmond T. Burke wrote in his book Canadian Bisley Shooting: An Art and Science that the mirage is more sensitive to wind variables than the flags because it has less momentum and inertia. This SSUSA article on mirage is well worth reading. Here’s a sample: “Mirage can make the difference between a shot landing in the X-ring and being victim to an unseen downrange breeze. Mirage’s ability to detect subtle breezes downrange is its true power. Its fluid movement… can provide wind direction and speed as well. Mirage is most effective on sunny, warm and hot days. Mirage is most noticeable in the mid-morning and early afternoon, but it does not follow these rules. Mirage is very good at identifying winds less than 12 mph, especially gentle breezes that are subtle enough not to bother moving the flags. Mirage will appear to be ‘bubbling up’ from the ground when there is no wind or a gentle head- or tailwind. This is often called ‘boiling’ and is the easiest to detect. The general rule of thumb is that the overall height of mirages produced by wind speed increases, the lower the mirage will be. A mirage that has large peaks and valleys in its waves is driven by a very light breeze. Wind speed reduces the size of the crest, making it harder to spot until the mirage disappears completely at 12 miles an hour. In other words, the faster the breeze, the higher the mirage’s waves will appear.
Diagram from SouthTexasShooting.org. This article was written by Glen Zediker and covers barrel breaking-in procedures. This article is especially useful when dealing with factory barrels. We warn readers — If you have hand-lapped custom barrels made by top barrel-makers, it is important to not do too much break-in. Clean sparingly and keep the barrel heat low. Abrasives should not be used aggressively. Wet-patched our Krieger and Brux barrels every 2-3 rounds for 20 rounds. The barrels shot flawlessly right from the start with minimal fouling. For factory barrels, however, a moderate break in process may be beneficial. Zediker says: “Lower-cost barrels will have more pronounced… imperfections in the bore [.] These imperfections are mostly tool marks that result from drilling and rifling. If the semi-automatic is an AR-15, you might find a burr at the location where the gas port was drilled. These imperfections are removed by break-in, which smoothens the interior. This Editor has been through a cartridge case-head blowout with a 9mm pistol. He is well aware of the risks and the damage that a blowout can cause to the pistol and magazine. Worst of all, the shooter. Even with new brass, there is always the possibility of a case failing. Even if the case is intact, primer failures can cause dangerous jets back towards the pistol shooter. Shooters should always wear protective eyewear when shooting. While we love our wheelguns, there is no doubt that they can cause forcing cone damage, especially with hot loads or if the cylinder-to barrel gap is too large. This article will explain how to inspect your revolvers and how to reduce the risk of getting forced cone damage. This article also covers how to properly clean your revolvers. This is important to prevent the buildup of lead and powder residues.
