Here’s a significant new addition to our knowledge base for Long-Range shooting. Hornady has released a new Ballistics Calculator that employs bullet profiles derived from Doppler radar testing and 3D projectile modeling. Hornady’s Patent Pending 4DOF™ Ballistic Calculator provides trajectory solutions based on projectile Drag Coefficient (not static G1/G7 ballistic coefficients) along with the exact physical modeling of projectiles and their mass and aerodynamic properties. This new 4DOF (Four Degrees of Freedom) calculator also accounts for spin drift and the subtle VERTICAL effects of crosswinds.
We strongly recommend you watch this video from start to finish. In greater detail than is possible here, this video explains how the 4DOF System works, and why it is more sophisticated than other commercially-offered Ballistics calculators. There’s a LOT going on here…
Aerodynamic Jump from Crosswind Calculated
According to Hornady, the 4DOF Ballistics Calculator “is the first publicly-available program that will correctly calculate the vertical shift a bullet experiences as it encounters a crosswind.” This effect is called aerodynamic jump. The use of radar-derived drag profiles, correct projectile dynamics, aerodynamic jump, and spin drift enable the Hornady® 4DOF™ ballistic calculator to provide very sophisticated solutions. Hornady says its 4DOF solver is “the most accurate commercially available trajectory program … even at extreme ranges.”
“Current ballistic calculators provide three degrees of freedom in their approach — windage, elevation, and range — but treat the projectile as an inanimate lump flying through the air,” said Dave Emary, Hornady Chief Ballistician. “This program incorporates the projectile’s movement in the standard three degrees but also adds its movement about its center of gravity and subsequent angle relative to its line of flight, which is the fourth degree of freedom.”
Using Doppler radar, Hornady engineers have calculated exact drag versus velocity curves for each bullet in the 4DOF™ calculator library. This means the 4DOF™ calculator should provicde more precise long range solutions than calulators that rely on simple BC numbers or drag curves based with limited data collection points. Emary adds: “The Hornady 4DOF also accurately calculates angled shots by accounting for important conditions that [other ballistic] programs overlook.”
“This calculator doesn’t utilize BCs (Ballistic Coefficients) like other calculators,” added Jayden Quinlan, Hornady Ballistics Engineer. “Why compare the flight of your bullet to a standard G1 or G7 projectile when you can use your own projectile as the standard?” That makes sense, but users must remember that Hornady’s 4DOF projectile “library” includes mostly Hornady-made bullets. However, in addition to Hornady bullets, the 4DOF Calculator currently does list seven Berger projectiles, six Sierra projectiles, and one Lapua bullet type. For example, Sierra’s new 183gr 7mm MatchKing is listed, as is Berger’s 105gr 6mm Hybrid.
This Video Explains How to Use Hornady’s New 4DOF Ballistics Calculator
Using the 4DOF™ Ballistic Calculator:
The Hornady 4DOF Ballistic Calculator provides trajectory solutions based on projectile Drag Coefficient (not ballistic coefficients) along with exact physical modeling of the projectile and its mass and aerodynamic properties. Additionally, it calculates the vertical shift a bullet experiences as it encounters a crosswind, i.e. “aerodynamic jump”. The use of drag coefficients, projectile dynamics, aerodynamic jump, and spin drift enable the 4DOF Ballistic Calculator to accurately measure trajectories even at extreme ranges. It is ideal for both long range and moderate distances and is available for the low-drag precision bullets listed in the drop down menu of the calculator. For calculating trajectories of traditional hunting and varmint bullets using BCs (ballistic coefficients), you can use Hornady’s Standard Ballistics Calculator.
Here’s an important announcement for anyone who uses a powder in the 4350 range. Alliant is now shipping the all-new Reloder 16 powder. The burn rate is slightly faster than Reloder 17, and a bit slower than Varget or Reloder 15. Notably, this new Reloder 16 powder is very temp stable. AccurateShooter.com was shown “top secret” test results comparing Reloder 16 with other popular propellants, including Hodgdon Extreme series powders. The results for Reloder 16 were remarkable. Reloder 16 showed extremely constant velocities even with very high ambient temps — so this is a powder you can shoot even on hot Arizona summer days.
This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures.
As a result, Reloder 16 offers outstanding temperature stability. Based on the test results we’ve seen, if you are using H4350 or IMR 4451 currently, you should definitely give Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.
Match and Hunting Cartridge Applications:
Alliant tells us that Reloader 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder may work very well in these popular match cartridges: 6XC, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Load Data Sheet shows a 2772 FPS load with 142gr SMKs in the .260 Rem.
Here’s a tip we feature every year or so, because it is something that costs nothing, yet can be very useful in the reloading process. With a simple, easy modification to a fired case, you can determine the length to lands in your rifle barrel. As long as you set the tension right, the measurements should be repeatable, and you’ve just saved yourself $31 — the price of a commercial OAL gauge.
To achieve best accuracy with a rifle, you must control bullet seating depth very precisely, so all bullets end up in the same place relative to the entrance of the lands, every time. There may be multiple cartridge OALs which prove accurate. However, with each, you first need to determine a “zero” point — a reliable, and repeatable OAL where the bullet is “just touching” the lands.
There are tools, such as the Hornady (formerly Stoney Point) OAL Gauge, that will help you find a seating OAL just touching the lands. However, the tool requires that you use a special modified case for each cartridge you shoot. And, while we find that the Hornady OAL Gauge is repeatable, it does take some practice to get in right.
Make Your Own Length-to-Lands Gauge with a Dremel
Here’s an inexpensive alternative to the Hornady OAL tool — a slotted case. Forum member Andris Silins explains how to create a slotted case to measure length to the lands in your rifle:
“Here’s what I did to find length to lands for seating my bullets. I made four cuts into the neck of fire-formed brass. Then I pressed the bullet in lightly and chambered the entire gauge. As the cartridge chambers, the bullet slides back into the case to give you length to lands. It took less than five minutes to get it cut and working. A little light oil in the barrel just past the chamber helps ensure the bullet does not get stuck in the lands. It works great and is very accurate.
I made the cuts using a Dremel with a cut-off wheel. You can adjust tension two ways. First, you can make the cuts longer or shorter. Longer cuts = less tension. If you used only three cuts insted of four you would get more tension. The trick is to be gentle when you open and close the bolt. If you ram the bolt closed you may wedge the bullet into the lands. When you open the bolt it helps to keep a finger or two near by to guide the case out straight because the ejector wants to push it sideways.”
Willa-Hyde, producers of firearms concealment storage systems, has introduced a handsome 6-foot tall chest of draws that hides firearms on either side. The side storage compartments, which can each hold multiple long-guns and 3-4 handguns, slide out to reveal their hidden contents. These slide-outs are secured by a steel pin locking system, which can only be unlocked with the provided rare earth magnet key.
True Capacity — the manufacturer Willa-Hyde claims this chest will hold a dozen long guns (six per side). We think 7-8 total long guns is more realistic.
When fully closed, the chest of drawers, crafted from Adler wood, is indistinguishable from any other piece of fine furniture.
Dimensions are 72″ tall x 33″ wide x 19″ deep, and the chest of drawers weighs 240 pounds. Price is $1995.00 plus a $250.00 delivery charge.
Crafted in Texas, the Willa-Hide storage cabinets were inspired by the inventor’s wish to keep his firearms away from inquisitive children: “Concealed gun cabinets have quickly become a ‘must have’ for any gun owner. [This concept] began when our co-founder wanted an easy way to keep his granddaughter from finding his guns, but at the same time still be able to get to them fast and easily when needed.” For more information on the Gun Chest of Drawers and other Willa-Hyde products (such as the Hidden Storage Wall Mirror), visit www.Willa-Hide.com.
John Whidden of Whidden Gunworks won his fourth Long Range National Championship at Camp Perry this month. In this article, the first of a three-part series on Long Range competition, John shares his thoughts on wind strategies and keeping one’s composure in pressure situations. John tells us Camp Perry was very challenging this year: “The 2016 Long Range Championship will go down in my memory as one with quick wind changes that made it very easy to shoot a 9.”
How to Win at Long Range Shooting
(Or at least what worked at the 2016 National Championships)
by John Whidden, 2016 National Long Range Champion
The NRA Long Range National Championships at Camp Perry Ohio are now in the history books and the competitors are home and reflecting on what they could have done to improve their score. I think anyone who has ever competed always knows they could have done even better if they had changed this detail or that aspect. This is the case regardless of where a shooter places in the standings, even for the winners.
This year the winds were reasonably tough. We mostly have either headwinds or winds from the 2-3 O’clock positions with speeds often in the 9-11 mph range. The changes came quickly and we had to be on our toes. Fortunately the course of fire allows the shooters some options. For the 1000-yard matches, we typically have 33 minutes for preparation, an unlimited number of sighter shots, and then 20 shots for record. Many shooters will shoot about 3-5 sighters and complete the task in about 15 minutes.
The 2016 Long Range Championship was definitely a match where you had to fight for every point during the whole event.
In preparation for shooting by watching the wind, I realized that the quick changes were going to add to the difficulty. Given the conditions, I chose a strategy of choosing only one condition to shoot in and waiting during any changes away from my desired condition. This plan meant that I would have to be very patient and plan to use all of my 33 minutes allotted time if needed.
The sun was shining for most of the matches so we had mirage to look at. There are plenty of flags at Camp Perry and I was glad for them!
As the wind speeds get higher I think a shooter should study the appearance of the flags. Some people look at the flag, and some really LOOK at the flags. The difference is observing things like how many ripples are in the flag, how far the flag stands off the pole, the angle of the flag in a headwind or tailwind, and how high the tip of the flag is relative to where the flag is attached to the pole. These details make all of the difference.
Time Management and Patience
Patience in wind reading can be a virtue. Choosing a condition and being patient has probably yielded more success in my long range wind reading than any other method. It’s not the only way to go, but on a day when you have time available and patience on your side it can yield a win! It should be obvious now that keeping a timer and managing the available time along with the number of shots remaining is an important part of this.
On August 10th, Vista Outdoor Inc. (NYSE: VSTO), officially opened its new 33,000-square-foot Utah corporate headquarters to the public with a ribbon cutting ceremony attended by state and local officials, community partners, members of the media, and employees.
“We are proud to call Farmington home,” said Vista Outdoor CEO Mark DeYoung. “We’re committed to being a strong partner for this community, and we value our relationships with the state, county and city leaders who helped make this headquarters a reality. We chose Utah because of its focus on outdoor recreation as an economic driver, the business-friendly environment, a talented workforce and balanced quality of life, as well as amazing geography and the availability of four seasons for outdoor recreation.”
Founded in 2015 when ATK (Alliant Techsystems*) spun off its sporting goods division from its aerospace business, Vista Outdoor is a leading global manufacturer of outdoor consumer products as well as firearms. Vista Outdoor’s 50 product brands include such well-known names as Bell Helmets, Blackhawk, Bushnell, CamelBak, CCI, Federal Premium Ammunition, and Savage Arms.
Building Constructed with Utah Wood and Stone
The new Headquarters building uses locally-sourced natural materials such as wood and stone in many design elements. The main lobby atrium includes a “living wall” made with live plants and a central staircase with an expansive view of the Wasatch Mountains, bringing the feeling of “outdoors” inside. The back lobby features a fireplace/campsite.
“Vista Outdoor and its brands are committed to conservation and environmental stewardship,” said DeYoung. “We believe in the responsible use of natural resources and in conserving the wild places where our employees and our consumers go to pursue their outdoor adventures.”
*Alliant Techsystems Inc. (ATK) came into being as an independent company in 1990 when Honeywell spun off its defense businesses to shareholders. ATK got into the ammo business in 2001 when it acquired Blount International. ATK grew with later acquisitions of Weaver Optics (2008), Blackhawk (2010), Savage Arms (2013), and Bushnell (2013).
Craters may look interesting on the moon, but you don’t want to see them on your primers. Certain mechanical issues that cause primer craters can also cause primer piercing — a serious safety problem that needs to be addressed. If you have a gun that is cratering primers (even at moderate pressure levels), there is a solution that works with many rifles — send your bolt to Greg Tannel to have the firing pin hole bushed.
Shooters who convert factory actions to run 6BRs, 6PPCs or other high-pressure cartridges should consider having the firing pin bushed. These modern cartridges like to run at high pressures. When running stout loads, you can get cratering caused by primer flow around the firing pin hole in the bolt face. The reason is a little complicated, but basically the larger the hole, the less hydraulic pressure is required to crater the primer.
A limited amount of cratering is normally not a big issue, but you can reduce the problem significantly by having a smith fit a bushing in the firing pin hole. In addition to reduced cratering, bushing the firing pin often produces more consistent ignition.
This is a highly recommended procedure that our editors have had done to their own rifles. Greg Tannel (Gre-Tan Rifles) is an expert at this procedure, and he does excellent work on a wide variety of bolts. Current price for a bushing job, which includes turning the firing pin to .062″, is $92.00, or $100.00 with USPS Priority Mail return shipping.
If you have a factory rifle, a bushed firing pin is the way to go if you are shooting the high-pressure cartridges such as 6PPC, 6BR, 6-6.5×47 and 6.5×47. This is one of the most cost-effective and beneficial upgrades you can do to your factory rifle.

We like the swivel (“S”) version of the Harris bipod. The swivel (actually tilting) capability of the bipod allows you to tilt (cant) your rifle around the bore axis to level the rifle on a side slope or uneven ground. Unfortunately, the swivel tensioner (friction knob) that comes standard with a Harris swivel bipod leaves much to be desired. The tensioning knob is hard to adjust with your fingers. The small knurled ring doesn’t offer enough leverage. When it’s tight enough to prevent movement it’s hard to release. For this reason, many folks replace the standard knurled ring with a rotating adjustment lever with push-button release. This works great and is easy to install.
While you can buy levers from various sources, Eabco.com has a tried-and-true system that works with both Harris and Caldwell XLA-S swivel bipods: “Our new S-Lever Tension Lever is an economical replacement for the friction tensioning knob to give you much better control and leverage.” For just $12.95, Eabco.com delivers all the parts you need for the upgrade. Shown below are instructions for installing the Eabco S-Lever.
It was a family affair in the F-TR Division at the Canadian F-Class Championships this past week. In a remarkable show of strength, Kevin and Will Chou, brothers from Aurora, Canada, finished first and second, topping a strong 94-shooter field that included past American and Canadian Champions. The “Chou One-Two” performance was one for the ages. Kevin finished first with 611-61V (“V” is the equivalent of an “X” in the USA), while Will (2014 Champion) scored 607-58V to finish second. A full thirteen points behind Will was third place Daniel Lentz at 594-34V.
Look hard at those numbers — Champion Kevin Chou was 17 points ahead of Daniel Lentz (the first American), with nearly double Dan’s V-Count. 17 points is a huge margin in this kind of competition. You have to hand it to the both Chou Brothers, Kevin and Will — they were “on fire” this past week at the Connaught Ranges outside Ottawa, Ontario. Kevin’s 611-61V equaled the top score in the F-Open division. That’s a major milestone for the F-TR bipod class shooting a .308 Win.
1. CHOU, KEVIN (Aurora, ON, Canada) 611-61V
2. CHOU, WILL (Aurora, ON, Canada) 607-58V
3. LENTZ, DANIEL(USA) 594-34V
4. HOGG, TRACY (USA) 593-41V
5. BURTON, ROBBY (USA) 591-44V
The F-TR event attracted top shooters from around the globe. Countries represented were: Australia, Canada, Ireland, South Africa, Ukraine, United Kingdom, and the United States. CLICK HERE for Complete F-Class Individual Results.

Report from the Canadian F-TR Championships
by Will Chou and Kevin Chou
Weather was extremely hot and humid for the first two days, resulting in thick mirage, a excellent indicator. In the Army & Navy match during the F-Open relay, wind velocity increased and shifted from right full value to left half value winds. Wind settled down for the last match of the day.
On the third day, mainly team matches, the rain challenged the marking staff with target faces deteriorating; a stop was called to the match after the 1st relay of the final. The match committee determined the best course of action, refaced the target during dry period and finished the remaining seeded final relays.
On the seeded final relay, my brother and I had no idea we’d be shooting together, as we’ve not discussed or paid any attention to scores for the entire match. It was a familiar position though, as we always practice paired together. Strangely, we’re not competitive with each other but rather assist one another to raise the level together. Come to think of it, that’s not just with my brother — we do that with everyone.
On that note, we feel the F-Class community has been raising each others level, bridging the gap between F-Open and F-TR. International teams have been assisting each other, most recently with Canadians and South Africans. Congratulations to South Africa for its well-deserved victory in the International Team Match.
We also congratulate the USA Team, which won the America Team Match, raising the bar yet again. Lastly, Shiraz Balolia’s “three-peat” in the F-Open Division was an incredible feat.
Big thanks to everyone at Bartlein barrels for their support to the Canadian F-Class team. Special thanks to Dan Pohlabel of Kreativ Solutions for the mirage cap, which allowed a better aim in thick mirage. Lastly, Clint Cooper of Duplin bipods, for the great product and his support.
Thank you all and we hope to see you on the firing line.
Shiraz Wins Third Canadian F-Open Championship in a Row: 2016, 2015, 2014
Grizzly Industrial President Shiraz Balolia pulled off a remarkable F-Open “THREE-PEAT” at the 2016 Canadian F-Class Championships. Shiraz won his third straight Canadian F-Class Championship, after winning the title in 2015 and 2014. Shiraz shot a 611-61V to edge, by way of tie-breaker, fellow American Emil Kovan, who also shot a 611-61V. That’s as close as it gets! Rounding out the podium in third place was another Yank, Dwayne Draggoo with 608-44V.
Stay tuned — We’ll have a full report on Shiraz’s notable three-peat F-Open performance (with his equipment and load details) later this week. We’ll also have reports on the Team competitions. There were three teams of 8 shooters taking part in the International, won by South Africa. In the Lum Trophy Match for teams of 4 shooters, there were 14 teams in the F-Open class, win by USFO Blue, and 11 teams in F-TR, won by USA Schwartzkopf.
