The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.” — William Arthur Ward
 Readers often ask us: “Is there a decent, easy-to-comprehend book that can help my wind-reading?” Many of our Forum members have recommended The Wind Book for Rifle Shooters by Linda Miller and Keith Cunningham. This 146-page book, published in 2007, is a very informative resource. But you don’t have to take our word for it. If you click this link, you can read book excerpts and decide for yourself. When the Amazon page opens, simply click the book cover (labeled “Look Inside”) and another screen will appear. This lets you preview the first few chapters, and see some illustrations.
Other books cover wind reading in a broader discussion of ballistics or long-range shooting, such as Applied Ballistics for Long-Range Shooting by Bryan Litz. But the Miller & Cunningham book is ALL about wind reading from cover to cover, and that is its strength. The book focuses on real world skills that can help you accurately gauge wind angle, wind velocity, and wind cycles.
All other factors being equal, it is your ability to read the wind that will make the most difference in your shooting accuracy. The better you understand the behavior of the wind, the better you will understand the behavior of your bullet. — Wind Book for Rifle Shooters

The Wind Book for Rifle Shooters contains straightforward guidance on the thought processes, techniques, and tactics used by expert wind-readers. The written text is supplemented by numerous easy-to-understand charts and illustrations. The authors show you how to put together a simple wind-reading “toolbox” for calculating wind speed, direction, deflection and drift. Then they explain how to use these tools to read flags and mirage, record and interpret your observations, and time your shots to compensate for wind. The essential wind-reading basics taught in this book can definitely help any shooter. Here are some reviews from actual book buyers:
I believe this is a must-have book if you are a long-range sport shooter. I compete in F-Class Open and when I first purchased this book and read it from cover to cover, it helped me understand wind reading and making accurate scope corrections. Buy this book, read it, put into practice what it tells you, you will not be disappointed. — P. Janzso
If you have one book for wind reading, this should be it. Whether you’re a novice or experienced wind shooter this book has something for you. It covers how to get wind speed and direction from flags, mirage, and natural phenomenon. The book also details methods for recording shots and improving your shooting and thus your wind reading skills. In my opinion this is the best book for learning to read wind speed and direction. — Muddler
I found this book to be something I have needed for quite a while. I have been shooting Long Range for 20 years and always had problems with the wind. I would just chase the spotter. This book makes it all make sense. — L. Cash
As far as I know this is the only book of its type. It’s very well written in a way that’s easy to understand for such a complex subject. The charts and graphs are extremely helpful. It’s a bit on the short side at about 146 pages but still packed with knowledge. — R. Johnson |

 We expect you’ve heard of David Tubb, 11-time NRA National High Power Champion. Without question, David is one of the greatest rifle shooters who ever lived. What you may not know is that David came from a family of shooters. David’s father, George Tubb, was a nationally-ranked High Power competitor. What’s more (now this may surprise you), David’s mother “Polly” was was a great shooter in her own right. When she wasn’t rearing a future Champion, Polly was hitting the X-Ring at rifle matches.
Pauline (“Polly”) S. Tubb of Canadian, Texas, earned several rifle championships during the course of her shooting career. In this photo, Polly took a moment to appear for a photo after winning the 1962 National Woman’s Bolt Rifle championship at Camp Perry. One shooter who competed against Polly observed: “I was there as a 1962 Pennsylvania State Team junior! I remember Polly. She beat some of the best Army and Marine shooters and always did it with style and good humor.”
Now that’s our kind of gal. God Bless you Polly. Thanks for being a Leading Lady of our sport.

We can predict, with some certainty, how long a light bulb will last (in use), or a shingle roof, or even a nuclear reactor. But how about barrels? Is there a way to reliably estimate barrel life based on known characteristics? This article explains one effort to quantify barrel life…
 How long will a barrel last before the accuracy “goes south”? There are so many variables involved (powder type, bore diameter, bullet coatings etc.) that it’s hard to predict. You might say “Well, my buddy has a .243 and he got 1500 rounds before the throat was shot out” — those kind of comparisons can be useful, but they’re not very scientific, and they won’t help much if you’ve got a gun in a new chambering (such as the 6.5×47) for which long-term test results are lacking.
Is there a more reliable way to predict barrel life — one that will work for a broad range of calibers? Well, Forum member MikeCr has developed an Excel spreadsheet that accounts for a number of variables, and gives a pretty good estimate of useful barrel life, whether you’re shooting a .223 Rem or a 338 Lapua Magnum. Mike’s program predicts barrel life using five variables: 1) Bullet Diameter; 2) Powder Charge weight; 3) Powder Heat Potential (KJ/kg); 4) Pressure (in psi); and 5) Bullet Coating (yes/no). Mike provides a table with Heat Potential ratings for most popular powder types. The user needs to know the pressure of his load. This can be estimated with QuickLOAD.
You can download the lastest version of Mike’s spreadsheet below. You’ll need Excel or an Excel viewer to open the file.
Click to Download Spreadsheet: Barrel Life Spreadsheet (Latest Version)
Shown below is Mike’s Spreadsheet, with variables for a 6BR shooting 105gr “naked” bullets with 30.3 grains of Hodgdon Varget powder. The formula predicts 2401 rounds of barrel life. That corresponds pretty well to what we’d expect for a 6BR — about 2500 rounds.
 
Mike observes: “There has been alot of discussion lately related to cartridge design and resulting barrel life. This is a really important factor to consider amongst a myriad of choices. Barrel life is controversial, and subjective. There are no clear-cut standards for comparison. But a few years ago, I put together a spreadsheet based on Bart Bobbit’s rule of thumb. It worked pretty good, only occasionally failing some tests when validated against posted barrel lives.
According to Ken Howell, I had to account for pressure. And Henry Child’s powder temperature testing provided another piece needed. So, I’ve tweaked it here and there to pass more tests. From 223rem to 300 UltraMagnum. Another element added, but turned off is shot interval. I would need way more tests to lock in on this. But everyone knows, the faster you shoot, the worse the barrel life.
Anyway, another factor hard to define is ‘accurate’ barrel life. This cannot be quantified without standards. Barrels are replaced when expectations are no longer met. I feel that a [barrel] passes peak potential in a finite period due to throat erosion. But that don’t mean it’s toast, if it still shoots well enough. It’s just as likely that many of us never see that peak potential anyway. It’s a slippery thing. Point-blank BR competitors will toss a barrel when it leaves the 1s. I could get another 4000 rounds from it, and be content with its performance, I’m sure.”
NOTE: Mike says: “This spreadsheet may show a lower barrel life than you prefer. But it pretty well spotlights cartridges to stay away from if you plan much time at the range or in dog town.”
Editor’s Comment: We want to stress that Mike’s spreadsheet is a helpful tool, but it is not a definitive “take-it-to-the-bank” indicator of barrel life. Mike cautions that predicting barrel life involves so many different factors (including how hot the barrel is run), that the task is a bit like predicting tread life on car tires. Still, the spreadsheet is very helpful. It can certainly warn us that some chamberings (such as the 6-284) are likely to be barrel burners. That can help you make a smart decision when choosing a chambering for your next rifle.

 Burris Signature Rings in Stock Again
Because they allow you to mount a scope without markings, to “pre-load” elevation, and to correct for windage mis-alignment, Burris Signature Rings (with Pos-Align inserts) are extremely popular. So popular in fact that Signature Rings, particularly the “Zee” models for Weaver rails, have been hard to find. Well, Signature Ring fans can now celebrate. Burris has recently shipped large supplies of Signature Rings, including the hard-to-find 30mm High Zees, to vendors across the country. If you’ve been waiting on these unique, affordable ring sets, get your orders in now.
Records Have Been Set with Signature Zee Rings
Are Signature Zees good enough for competition? Absolutely. Some folks scoff at these Burris rings, given their low price. A set of 1″-diameter Sig Zees cost less than $35.00 at Midsouth Shooters Supply.

F-Class competition will be featured on this week’s episode of Shooting USA television. This week, Shooting USA takes an inside look at the rapidly-growing sport of F-Class shooting, with coverage of both F-TR and F-Open competition at 600 yards and beyond. This show will air three times on Wednesday, October 23rd, on the Outdoor Channel (see air times by region below). This episode will also feature the historic 1907 Winchester, a choice of gangsters in the 1920s.
 The Shooting USA Hour on Wednesdays:
AIR TIMES BY TIME ZONE
Eastern Time 3:30 PM, 8:30 PM, 12:00 Midnight
Central Time 2:30 PM, 7:30 PM, 11:00 AM
Mountain Time 1:30 PM, 6:30 PM, 10:00 PM
Pacific Time 12:30 PM, 5:30 PM, 9:00 PM
F-Class Basics
The ‘F’ in F-Class stands for Farquharson. Canadian George Farquharson is credited with founding the sport in the 1990s. Farquharson wanted to create a discipline for fellow older shooters whose fading eyesight made it difficult to compete in traditional iron-sight high power matches. In 2007, the United States NRA officially recognized the prone shooting disciple. Since then the sport has grown rapidly. Over 350 shooters attended the 2013 F-Class Nationals in Raton, NM.
F-Class is similar to High Power rifle shooting, with competitors taking turns in the pits, pulling and scoring targets. Unlike conventional High Power shooting with iron sights, F-Class shooters use scopes (with up to 80x max power, though the most popular scope is still probably the 12-42x56mm Nightforce Benchrest).
All F-Class competition is shot prone. Competitors are classified into two divisions, F-TR (Target Rifle) and F-Open. F-TR rifles must be shot from bipod, and must be chambered for either the .223 Rem or .308 Win cartridges. Max F-TR gun weight is approximately 18.18 pounds, including bipod. In the F-Open division, rifles can weigh up to 10 kg (22 pounds) and front rests can be used (but you may shoot from a bipod if you wish). F-Open competitors may shoot any cartridge which is .35 caliber or under.

 The U.S. Supreme Court has agreed to adjudicate a case involving a firearms purchase and subsequent resale to a family member. The case of Abramski v. United States, arises from the prosecution of Bruce James Abramski, Jr., a former Virginia police officer, for allegedly making a “straw purchase” of a Glock handgun. Abramski had lawfully purchased a Glock pistol in Virginia, then later resold the Glock to his uncle, a resident of Pennsylvania. Both purchases were conducted through FFLs, with full background checks, and both parties were legally entitled to own a handgun. Abramski arranged the sale in this fashion to take advantage of a discount available to him as a law enforcement officer.
Abramski was indicted and prosecuted for violating Federal laws against “straw purchases”, specifically making a false declaration on BATFE Form 4473, which is a violation of 18 U.S.C. § 922(a)(6). Abramski challenged the indictment, but the District Court ruled against him and the U.S. Fourth Circuit Court of Appeals upheld the District Court’s decision. However, the Fourth Circuit acknowledged that there was a split of authority among the Circuits as to whether § 922(a)(6) applied in a case like this one, where the ultimate recipient of the firearm was lawfully entitled to buy a gun himself. The Fourth Circuit’s ruling conflicts with previous decisions by the Fifth Circuit holding that “straw purchaser” laws are NOT violated if both the original purchaser and secondary buyer are legally entitled to own a firearm. See United States v. Polk, 118 F.3d 286 (5th Cir. 1997).
 The key issue is whether Abramski committed a crime by buying a gun, and then promptly re-selling it to another person who was legally entitled to own the firearm. The government argues that Abramski broke the law when he checked a box on Form 4473 indicating he was the “actual transferee/buyer of the firearm”.
Arguably, Abramski’s purchase and subsequent resale did not violate the intent of the law, since the Glock never ended up in the hands of a criminal (or someone who was otherwise barred from gun ownership). The John Floyd Law Firm explains this argument:
“Attorneys for Abramski sought to have the indictment dismissed on the legal premise that because Abramski and the uncle were both legally entitled to purchase a firearm, Abramski could not be a ‘straw purchaser.’ Attorneys further argued that Abramski’s ‘yes’ answer to question 11(a) on the 4473 that he was actual buyer of the Glock was never intended to be punished under the Gun Control Act of 1968 if the buyer had a legal right to purchase the weapon. The attorneys theorized that the intent of Congress in passing this Act was ‘to make it possible to keep firearms out of the hands of those not legally entitled to possess them.’
Second Amendment proponents strongly believe there is nothing wrong with a nephew purchasing a weapon he is legally entitled to purchase with the specific intent to sell it to an uncle who is also legally entitled to purchase a weapon. The Fifth Circuit says such a purchase is legal because both parties are legally entitled to purchase and possess a firearm. The Sixth and Eleventh Circuits [and now the Fourth Circuit] say these legal entitlements do not matter.”
Soon the U.S. Supreme Court will decide which interpretation of the law is correct.

Report by Boyd Allen
This pistol belongs to Dan Lutke, a Bay Area benchrest shooter who publishes the results for the Visalia matches to the competitors and the NBRSA. He has been an enthusiastic competitor for an number of years, at various ranges, notably Visalia and Sacramento. The action is a Remington XP-100, to which a Kelbly 2 oz. trigger has been fitted. On top is an old Japanese-made Tasco 36X scope (these were actually pretty darn good). The Hart barrel (a cast-off from Dan’s Unlimited rail gun) was shortened and re-chambered for the 6x45mm, a wildcat made by necking-up the .223 Remington parent case. The custom stock/chassis was CNC-machined by Joe Updike from 6061 Billet Aluminum to fit the XP-100 action and mount a target-style AR grip with bottom hand rest. The gun was bedded and assembled by Mel Iwatsubu. In his XP-100 pistol, Dan shoots 65gr custom boat-tails with Benchmark powder.
 
TEN Shots in 0.303″ at 100 Yards
How does Dan’s XP-100 pistol shoot? Look at that target showing TEN shots at 100 yards, with eight (8) shots in the main cluster at the top. The ten-shot group measures .303″ (0.289 MOA), as calculated with OnTarget Software. Not bad for a handgun! What do you think, can your best-shooting rifle match the 10-shot accuracy of this XP-100 pistol?
This diagram shows the most common 6x45mm wildcat, which is a necked-up version of the .223 Remington parent cartridge. NOTE: The dimensions for Dan Lutke’s benchrest version of this cartridge may be slightly different.

Here’s a feel-good story about a talented young shooter.
Article based on report by Lars Dalseide, for NRA Blog.
Finding the X-Ring while taking part in NRA’s National Rifle and Pistol Championships can be challenging enough. Finding the X-Ring from three positions during the smallbore rifle phase of the championships can be even more trying. But Amy Fister, winner of this year’s NRA 3-Position Rifle High Woman title, found it with no trouble at all. A surprising result given her wry self-description.
“I’m a nerd,” she said with a laugh. “I’m very dedicated to my studies.”
Based out of Kutztown, Pennsylvania, Fister walked away from the 3-Position Awards Ceremony with three titles: High Woman with Metallic Sights, High Civilian with Metallic Sights, and High Woman Overall. Fister finished with a score of 2374 – 140X (good for 7th overall). “Last year I was close but not close enough,” said Fister. “I guess this year it was my time.” Seeing her on stage, winning award after award, it’s hard to believe that it almost didn’t happen — she nearly fell victim to the summer heat at Camp Perry.
Fighting Dehydration at Camp Perry
About halfway through the National Championship match, Fister was setting up targets when she realized something was wrong: “I was delusional, seeing things,” Fister explained. “After setting up my target, it wasn’t there. I started chasing down the target guy for another one. It was an interesting and a little bit scary of an experience.”
She was dehydrated. Heartbeat rapid, extremely lethargic, unsteady on her feet — she recognized the signs and started back for the line. Pulling a bottle of Gatorade out of her bag, she gulped until it emptied. Feeling a touch steadier, she made for the water coolers behind the line. A few cups later and she was ready to proceed. “Luckily it happened during prone,” she said with a laugh. “Standing would have been a different story.”
How a Nerd Became a World-Class Rifle Shooter
Starting as far back as she can remember, Fister was out shooting with her dad. First as the official gear porter, then as a huntress. “Deer and goose, that’s what we went for,” she said. “I go out deer hunting whenever I can, but it cuts into my shooting time. You’ve got to find a happy medium.”
 Though it was dad who first put a rifle in her hand, it was her sister Valerie who started her down the competitive trail. Like most stories of sibling rivalry, big sister joined the rifle team so little sister (Amy) wanted to also. A little practice, a little patience, and it all came together — so well in fact that Amy has earned a shooting scholarship to the University of Memphis. But her ambitions don’t stop there. They reach as far as Rio de Janeiro, site of the 2016 Olympics.
“I missed a spot on the U.S. Team by two points. Now the goal is to be part of the Olympic Rifle Team in 2016. Problem is that I don’t want my scores to drop and I don’t want my grades to drop.
“My goal is to become a pediatrician and an Olympian. Guess I’ll just find a way.”
