Henry’s Hammer — State-of-the-Art .284 Shehane for 1K BR

Henry Pasquet IBS 1000 yard Nationals champion two gun overall .284 shehane

We’ve been giving a lot of coverage to tactical rigs and gas guns lately, so we though it was time to showcase a purebred, state-of-the-art 1000-Yard Benchrest rig. This article features the impressive .284 Shehane Light Gun used by Henry Pasquet to capture the 2013 IBS 1000-yard Nationals.

With a 5″-wide “hammerhead” front and a special 3″-wide bag-rider plate in the rear, this 17-lb rig is ultra-stable in the bags, and tracks like a dream. In this story, Henry explains his set-up plus his processes for loading super-accurate ammo. Every long-range shooter can benefit from some of tips revealed here. And F-Class guys — if you’re shooting a .284 Win-based case in F-Open you should definitely read Henry’s precision reloading advice.

EDITOR: Guys, there is a ton of solid gold information in this article — take your time and read it carefully.

Henry Pasquet IBS 1000 yard Nationals champion two gun overall .284 shehaneYes old dogs can learn new tricks. Just five years ago Forum member Henry Pasquet (aka “HenryP”) got started in 1000-yard benchrest shooting. He was 66 at the time. Henry worked hard, learned fast, and pursued accuracy with a vengence. That all paid off when Henry won the 2013 IBS 1000-yard Nationals this summer, finishing as the Two-Gun Overall National Champion. Henry was kind enough to talk about his rifle, his reloading methods, and his strategy for success. In fact, Henry was eager to share “everything he knows, so that other guys can fast-track their learning process”. Henry told us: “I want to share every lesson I’ve learned, so that other guys can improve their game and enjoy the sport more.” Henry also wants to encourage other senior shooters: “If you pay attention to details (when reloading), and get a good rifle with a good barrel, age is not a handicap. With a good set-up, older guys can compete with anyone out there. This is one sport where you can be a champion in later life.”

Q&A with Henry Pasquet, IBS 1000-Yard National Champion

Q: First, do you have any advice for older shooters getting started in their golden years?

Henry: You’re never too old. In this sport, you can excel even in your 60s, 70s and beyond. At this stage in life, we now have the time and money to get good equipment and rifles. Plus, our years of work experience help us to think, analyze, and thereby make progress. In this game, we older guys can definitely compete on a par with younger shooters.

HARDWARE

Q: Tell us about your Nationals-winning rifle and bench gear. Is there anything unique about your hardware that gave you an edge?

Henry: At the Nationals, I used my 17-lb Light Gun for both Light and Heavy Class. This rifle has a 1.55″, round BAT LP/RE action, fitted with a Bartlein barrel chambered for the .284 Shehane (an improved version of the .284 Winchester). The barrel was near-new; this was the first time I had used it this year. A great barrel and great batch of Berger 180gr VLDs all made a difference. Jay Cutright chambers my barrels. Jay’s metal-work is so precise that I can screw any barrel he’s chambered to any BAT action I own. The laminated stock was modified by Tommy Shurley from a standard 3″-wide fore-end to a 5″-wide True-Trac with an adjustable 3″-wide rear plate. It’s not pretty but it tracks like a Heavy Gun stock. Tommy made my other stocks as well.

Protektor sand bag 3M material IBS 1000 yard Nationals champion two gun overall .284 shehaneOn top is a Nightforce 12-42x52mm Benchrest scope with CH-3 reticle. I used a Fulghum (Randolph Machine) front rest with an Edgewood bag made with the low-friction 3M material. In the rear I use a special-order Protekor rear “Doctor” bag with ears spaced 3 inches apart. The rear bag also has the new 3M material on contact surfaces (photo at right).

Q: During the Nationals, at the last minute you switched guns. Why did you go from a 6mm Dasher to a 7mm Shehane?

Henry: I had planned to use my Light and Heavy Dashers, but after placing the Dasher on the ready line, decided to switch to the .284 Shehane. It was still early in the morning and I felt that the heavier bullets would be easier to see against the berm. The Dasher had actually been giving tighter groups under perfect conditions, but seeing the impact is important.

Q: Tell us about the combined tuner/muzzle brake on some of your barrels. How does this improve rifle performance and how do you set the “tune”? Do you tune the barrel to the load?

Henry: I use a tuner or tuner/brake on every barrel. I started with Time Precision tuners. Art Cocchia advised getting a load with a good known accuracy node with minimum extreme spread, which controls vertical. Do not go for the hottest loads, which just reduces brass life. Then use the tuner and tune the barrel to the load. The .284 Light Gun needed a muzzle brake and tuner. I had a local gunsmith cut a thread on the muzzle brake for a tuner I got from Sid Goodling. (Eric Bostrom developed an almost identical unit at the same time. I use Eric’s tuner/brakes on all my new barrels.) Just before Nationals, I tried going up and down one marker. Down one mark cut the group in half! Think how much range time (and barrel life) that saved me. Using a tuner is easier than messing around changing loads and tweaking seating depths. Tuners definitely can work. Last year I shot a 3.348″ 10-shot group at 1000 with my .284 Win Heavy Gun fitted with a Time Precision Tuner.

Q: What are the advantages of your stock’s 5″-wide fore-end and 3″-wide rear plate? Is there a big difference in tracking and/or stability? Does the extra width make the rifle easier to shoot?

Henry: I had true Heavy Guns with 5-inch fronts and 3-inch rears. They tracked well. I felt the same result could be had with a Light Gun. I talked two stock makers into making them. I initially had the standard rear stock until Tommy Shurley and Mike Hearn came out with an adjustable rear plate. The stocks track perfectly. You can see your scope’s crosshairs stay on the target the whole time and push the rifle back for the next shot. There is no torquing (gun wobbling) when cycling the bolt. Us old guys need all the help we can get. I am getting rid of my 45-pound Heavy Guns and replacing them with Light Guns with heavy barrels.

Q: Some people say the .284 Shehane is not as accurate as the straight .284 Winchester. You’ve proved them wrong. Why do you like the .284 Shehane? More speed, less pressure?

Henry: The reason I rechambered my 7mm barrels to .284 Shehane was not velocity, pressure, or brass life. It was all about bolt lift. My straight .284 almost required me to stand up to eject brass. I damaged an extractor and had to send the bolt back to BAT. With the .284 Shehane, my bolt cycles like there is no case to eject.

Reloading Methods

Q: People want to know about your load and your loading methods. What can you reveal?

Henry: For my .284 Shehane at the Nationals, I loaded 52.5 grains of Hodgdon H4350 and Federal BR-2 primers behind Berger 180gr VLDs. I usually anneal the brass each winter. I have used the same brass for years. I use Redding bushing dies, apply Imperial sizing wax, resize, wipe off wax, clean and uniform the primers pockets using the RCBS Trim Mate Case prep center, then apply Imperial dry neck lube with a bore mop.

K & M arbor seating force dial gaugeTo dispense powder, I use a RCBS ChargeMaster set 0.1 grain below my desired load and then weigh them on a Sartorius GD-503 magnetic force restoration scale to get identical charges. I use a K&M Arbor Press with seating force gauge when seating the bullets with a Wilson inline die. My “target” seating force on the K&M dial is 20-23 units for Dashers and 35-40 units for the .284 Shehane. I put any variables aside for sighters. I do not weigh brass, bullets, or primers. My bullets were so consistent that I did not sort by bearing surface. I did trim the Berger VLDs to the shortest bullet length with a Hoover Trimmer, and then pointed the meplats just enough to close them with a Whidden pointer. I sort my bullets to 0.005″ overall length, rejecting about five percent.

Q: What kind of precision are you looking for in your reloads? Do you trickle to the kernel? Does this really help reduce extreme spread?

Henry: I try to keep my charge weights consistent to one kernel of powder. I use the Omega powder trickler with a Sartorius GD-503 lab-grade balance to achieve that. For accurate dispensing, put very little powder into the Omega so you can drop one kernel at a time. Single digit ES (Extreme Spread) is the goal. This does make a difference at 1000 yards. If you get the same push on the same bullet with the same neck tension, good things are going to happen.

Q: You believe consistent neck tension (i.e. grip on the bullet) is really important. What methods are you using to ensure consistent bullet release?

Henry: I apply Imperial dry neck lube to the inside of my case-necks with a bore mop. The K&M arbor with seating force gauge shows the need to do this. If you put a bullet into a clean case, it will be jerky when seating the bullet. You may see 40 units (on the K&M dial) dropping to 20, then slowly increasing pressure. I explained to a friend that not lubing the neck is like overhauling an engine without lubing the cylinders. Smooth entry gives the bullets a smooth release.

Barrel Cleaning

Henry Pasquet IBS 1000 yard Nationals champion Carb out Carb-out WipeOut .284 shehaneQ: You go 60-80 rounds between cleaning and the results speak for themselves. What is your barrel cleaning procedure? Do you think some guys clean too often or too aggressively?

Henry: I cringe when I see people wearing out their barrels with bronze brushes between relays. I clean my barrels at the end of each day when I get home. I shot my best-ever 1K Heavy Gun group (3.348″) at day’s end after 60 to 80 rounds. After trying other solvents, I have gone back to Wipe-out’s Carb-Out and Patch-Out products. I use about four patches of Carb-Out, let it sit a few minutes, then use one stroke of a nylon brush followed by Patch-Out until the barrel is clean. I use a bore mop to clean inside the chamber, then some Break Free LP on the bolt followed by bolt grease on the lugs and cocking part. I use a bore guide when anything goes down the barrel.

Shooting Skills and the Learning Process

Q: Henry, you can shoot long-distance on your own property in Missouri. How important is practice, and what do you do during a typical practice session?

Henry: I can shoot 1000 yards on my farm. I have a concrete bench using a slab from a yard furniture place on concrete blocks. Two 4 x 8 sheets of plywood hold four IBS targets. I never practice. I only test, keeping a notebook with all the info. I do most of my testing at 300 to 500 yards, shooting off my deck so I can see my shots immediately.

Protektor bag benchrest rifle Light gun IBS 1000 yard Nationals champion two gun overall .284 shehane

Q: How much of your success do you credit to really accurate rifles, versus superior shooting skills?

Henry: I do not consider myself another Carlos Hathcock or some master marksman. I am an average 1000-yard shooter, but I do work hard getting the most out of my rifles. Four other people have shot their first 1000-yard matches with my rifles, including my wife, and all of them won relays! I loaned my Dasher to another shooter two years ago and he got second at the 600-yard Nationals. Others will tell you that the rifle must be “on” to win. If your barrel or bullets are average, don’t expect to perform above average in competition.

Q: What you do enjoy most about long-range benchrest shooting? What are the attractions of this sport?

Henry: The sport offers good people and a real challenge. 1000-yard shooting keeps us all humble, but we still keep trying to see how good we can do. I am thankful for Robert Ross providing the only match location that I can shoot regularly.

Q: Henry, you have been a Forum member for many years. Have you learned important techniques from other Forum members and other shooters?

Henry: I have followed the AccurateShooter Forum since 2008. At my age I am not good at computers. I copied and analyzed many articles, especially on the .284 and the Dashers. Without AccurateShooter.com, I would probably still be shooting double-digit (10″+) groups at 1000 yards, and I sure wouldn’t have my name on a National Championship trophy.

Q: You are in your 70s now and have only been shooting competitively for a few years. How did you get so good so fast? How did you manage to beat shooters who are decades younger?

Henry: I had 20/10 vision when I was young, but am down to only 20/20. I have been interested in long range shooting for a long time including ground hog hunting. I went to some VHA jamborees also. In 2008, I went to the Williamsport Benchrest School with a friend from Pennsylvania, John Haas. We would compare notes frequently. I bought a BAT three lug from Tom Mousel in Montana. We also compared notes and made each other better. At IBS matches I studied other shooters’ equipment and techniques. I tried some, accepting some and rejecting some.

Here’s my advice:
Always be ready to learn something new. If it makes sense, try it. I would also encourage other older shooters not to quit. Stick to it. You can make enormous progress in a few seasons.

TECH TIP: How to Remove a Stuck Cartridge Case from a Die

stuck72

To err is human… Sooner or later you’ll probably get a case stuck in a die. This “fix-it” article, which originally appeared in the Western Powders Blog, explains the procedure for removing a firmly stuck cartridge case using an RCBS kit. This isn’t rocket science, but you do want to follow the directions carefully, step-by-step. Visit the Western Powders Blog for other helpful Tech Tips.

Curing the Stuck Case Blues

decapstem72Sticking a case in the sizer die is a rite of passage for the beginning handloader. If you haven’t done it yet, that’s great, but it probably will eventually happen. When it does, fixing the problem requires a bit of ingenuity or a nice little kit like the one we got from RCBS.

The first step is to clear the de-capping pin from the flash hole. Just unscrew the de-capping assembly to move it as far as possible from the primer pocket and flash hole (photo at right). Don’t try to pull it all the way out. It won’t come. Just unscrew it and open as much space as possible inside the case.

Place the die upside down in the padded jaws of a vise and clamp it firmly into place. Using the supplied #7 bit, drill through the primer pocket. Be careful not to go too deeply inside the cartridge once the hole has opened up. It is important to be aware that the de-capping pin and expander ball are still in there and can be damaged by the bit.

Drill and Tap the Stuck Case
taping72drilling72

Once the cartridge head has been drilled, a ¼ – 20 is tap is used to cut threads into the pocket. Brass is relatively soft compared to a hardened tap, so no lube is needed for the tapping process. RCBS says that a drill can be used for this step, but it seems like a bit of overkill in a project of this nature. A wrench (photo above right) makes short work of the project.

RCBS supplies a part they call the “Stuck Case Remover Body” for the next step. If you are a do-it-yourselfer and have the bit and tap, this piece is easily replicated by a length of electrical conduit of the proper diameter and some washers. In either case, this tool provides a standoff for the screw that will do the actual pulling.

pulling72fingers72

With an Allen Wrench, Finish the Job
Run the screw through the standoff and into the tapped case head. With a wrench, tighten the screw which hopefully pulls the case free. Once the case is free, clamp the case in a vice and pull it free of the de-capping pin. There is tension here because the sizing ball is oversized to the neck dimension as part of the sizing process. It doesn’t take much force, but be aware there is still this last little hurdle to clear before you get back to loading. Don’t feel bad, everyone does this. Just use more lube next time!

Sean Murphy, Nightforce Optics Marketing Manager, shoots what he sells. Sean recently competed at the inaugural PRS Gas Gun match held February 17-19, 2017 at the CORE Shooting Solutions range in Baker, Florida. Here is Sean’s report:

PRS Gas Gun Match at CORE by Sean Murphy
The series-opening PRS Gas Gun match is in the books. Ryan Castle put on a fun match to help set the tone for what this series will become. There were plenty of challenges for both the PRS and 3-Gun competitor. The best way I can explain it is to go as fast as you can because time matters, and then don’t miss because the penalties for leaving targets are harsh. I am looking forward to shooting more of these matches and would encourage any of my PRS and 3-Gun friends to give one a try.

PRS Gas Gun Nightforce Optics CORE Florida AR15 AR

PRS Gas Gun Nightforce Optics CORE Florida AR15 ARCongratulations to the USAMU’s Tyler Payne (right) for the exhibition on how to shoot this and a very commanding overall win. [Payne won overall and high military with a score that was 25% higher than the next-best finisher.] Also congrats to Rhett Walters and Terry Cross for their first-place and second-place finishes in Tac Lite (and 2nd/3rd overall). I was fortunate to place third in Tac Lite and 4th overall for the match. Thank you to FALKOR Defense for the prize table contribution.

Squad 4 was a lot of fun and I was fortunate to shoot with some of our nation’s finest warriors and competitors. It was great to see various military guys in attendance refining their craft. It was great as always to see all of my friends at the match and make new ones. While I love shooting, the people are why I keep coming back.

Gas Gun Match Loads — Short Range vs. Long Range
The .223/5.56 guns had some lag time waiting on shot impacts. I believe the long-term solution may be to find a light and fast load for closer stages for near-instant reaction time and use a heavy load for the long shots to see splash and get the target to move a little more. — Sean Murphy

GEAR Selections for PRS Gas Gun Matches

OPTICS for the PRS Gas Gun Series
I was proud to see Nightforce Optics well represented on guns, with the ATACR 4-16×42 F1 seeming to be a solid choice for many competitors. My optic of choice is an ATACR 16x F1 with a Horus H59 reticle. For this style match the magnification range, Zero-Hold adjustment and wide field of view are a perfect combination. We had some smoke roll in from area fires on Sunday, and the ED glass was an aid in finding the targets in deep haze and shadows. Because of the time component [stages are “on the clock”], being able to shoot with holdovers is key, as well as being able to make fast corrections on follow-up shots. The H59 or TReMoR 3 will be strong contenders for this.

PRS Gas Gun Nightforce Optics CORE Florida AR15 AR

BARREL Choice — Proof Carbon-Wrapped
I shot a 20″ PROOF Research carbon fiber-wrapped barrel that was expertly installed by Greg Hamilton himself. It shot lights out while keeping the gun light and handy for movement and getting in/out of multiple positions.

TRIGGER Choice
While I like the Geissele Automatics, LLC Super 3-Gun (S3G) trigger for carbines as it’s really fast, I went with their DMR trigger for a more refined break that helped on the 600-800 yard shots.

The preferred rifle color choice at the first PRS “Gasser” Match was definitely black…
PRS Gas Gun Nightforce Optics CORE Florida AR15 AR

AMMUNITION Choice (.223 Rem/5.56x45mm)
My ammunition of choice for this match was Black Hills 77gr .223 Rem. The ammo shot outstanding, especially at longer ranges. I believe the long-term solution may be to find a light and fast load for closer stages for near instant reaction time and use a heavy load for the long shots to see splash and get the target to move a little more. The .223/5.56 guns had some lag time waiting on shot impacts, so finding a way to speed that up over 20 or so shots might save a few seconds per stage.

BALLISTICS Solver and Wind Meter
I continue to love my Kestrel 5700 AB. It was very confidence inspiring to show up at the range, get my atmospherics and run accurate data to get first round hits all the way to 800 yards.

BAGS and Gear
The precision rifle game seems to require an assortment of bags and other gear for the various shooting positions to conquer. My Armageddon Gear and Wiebad bags and gear continue to deliver and hold up to much abuse.

PRS Gas Gun Series Rules

For the new PRS “Gasser” Competition, the PRS developed rules on gun types, scoring, match timing, penalties, safety and other key topics. CLICK HERE for Full PRS Gas Gun Series Rules.

Scoring and Penalties
The Gas Gun Series utilizes a time plus penalty-based scoring system for all match scoring. This means the score is the shooter’s total combined time on all stages plus any penalties accrued.

Penalties are as follows:
30 seconds for any rifle targets not engaged or neutralized.
15 seconds for any pistol targets not engaged or neutralized.
15 seconds for hitting a “No Shoot” target.
No more than 50% of the stages at a match can utilize an unlimited round count. At least 25% of the targets in Gas Gun Series match must be 2 MOA or smaller. Max distance is 800 yards.

Open Division: The Open Division rifles will not exceed a caliber of .30 or a velocity of 3,200 fps. A match DQ will result any rounds over the speed limit of 3,200 fps (+/- 32 fps for environmental factors and equipment discrepancies). Match Officials may request at any point during a match that a competitor fire their rifle through chronograph. If the bullet exceeds the 3,200 fps speed limit, the shooter will receive an automatic match DQ.

Tactical Light Division: Intended to allow competitors the opportunity to compete using traditional military and law enforcement caliber. This promotes Active Duty military and law enforcement competitors use of their Service and Department-issued rifles. Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington calibers only. Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps.

Figuring Optimal RPM with Berger Twist-Rate Stability Calculator

Berger twist rate calculator
Erik Dahlberg illustration courtesy FireArmsID.com.

Berger twist rate calculatorBerger Twist-Rate Stability Calculator
On the updated 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 very cool tool tells you if your chosen bullet will really stabilize in your barrel.

LIVE DEMO BELOW — Just enter values in the data boxes and click “Calculate SG”.

How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculater 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).

Tough Field Locker Case is Great for Long-Barreled Match Rifles

Plano double gun case Amazon Field locker

Readers often ask us, “Who makes a durable, airline-worthy hard case big enough for long-barrel match rifles?” Here’s a good option — the Plano Field Locker Double Long Gun Case.

A full 54″ long inside, this Plano case will hold big rifles with 30-31″ barrels. This case is very sturdy, and will survive rough handling at airports. The case has tough latches, watertight seals, and wheels for easy transport. Right now this case is just $111.50 with Free Shipping for Amazon Prime members. This is the lowest price ever on Plano’s largest gun case.

One buyer confirms this Plano case will fit long match rifles: “It holds two 17-lb bench rifles with 30″ barrels. It is very heavily made — even more stout than a Pelican 1750. Only draw back is the weight with two guns, over 60 pounds. But for shipping guns to a match, even the airline baggage handlers couldn’t damage this case! Case is great for two long guns!” (Smitty)

Another certified buyer states: “I bought this case for a Savage 110BA .338 Lapua Magnum, and it’s so nice that I just bought a second one for a 50 BMG. There are very few rifle cases that will fit the larger rifles… and this is a great choice for the heavy caliber rifles with long barrels.” (Bruce L.)

Mirage Is Your Friend — Great Article on Reading Mirage

South Texas Mirage Reading article
Diagram from SouthTexasShooting.org.

South Texas marksmanship trainingThere was an excellent article about Mirage created for the South Texas Marksmanship Training Center (STMTC) website a while back. This article explains what causes mirage and how mirage can move the perceived aiming point on your target. Most importantly, the article explains, in considerable detail, how you can “read” mirage to discern wind speeds and wind directions.

Mirage Is Your Friend
While hot days with lots of mirage can be frustrating, mirage can reveal how the wind is flowing (and changing). If you learn how to recognize and read mirage patterns, you can use that information to shoot higher scores. That’s why many leading long-range shooters tell us: “Mirage is your friend.” As the STMTC article explains: “A mirage condition is not a handicap, since it offers a very accurate method of perceiving small wind changes[.]”

CLICK HERE to Read Complete Mirage Article

Mirage Illustrated with Diagrams
With simple but effective graphic illustrations, this is one of the best explanations of mirage (and mirage reading) we have found on the internet. This is a “must-read” for any serious competitive shooter. Here is a brief sample from the article, along with an illustration. NOTE: the full article is six times longer and has 8 diagrams.

South Texas Mirage Wind Diagram displacement

The term “mirage” as used by the shooter does not refer to a true mirage, but to heat waves and the refraction of light as it is bent passing through air layers of different density. Light which passes obliquely from one wind medium to another it undergoes an abrupt change in direction, whenever its velocity in the second medium is different from the velocity in the first wind medium; the shooter will see a “mirage”.

The density of air, and therefore its refraction, varies with its temperature. A condition of cool air overlaying warm air next to the ground is the cause of heat waves or “mirage”. The warm air, having a lower index of refraction, is mixed with the cooler air above by convection, irregularly bending the light transmitting the target image to the shooter’s eye. Figure 1 shows (greatly exaggerated) the vertical displacement of the target image by heat waves.

Heat waves are easily seen with the unaided eye on a hot, bright day and can be seen with spotting scope on all but the coldest days. To observe heat waves, the scope should be focused on a point about midway to the target. This will cause the target to appear slightly out of focus, but since the high power rifle shooter generally does not try to spot bullet holes, the lack in target clarity is more than compensated by clarity of the heat waves.

Bushnell Brawl Featured on Shooting USA Today

ShootingUSA Bushnell brawl Impossible Shots

ShootingUSA Bushnell brawl Impossible ShotsThis Wednesday, February 22nd, Shooting USA TV features the Bushnell Brawl, a tactical competition that draws top long-range shooters from military, law enforcement and civilian shooting communities. The match is held at the famed Rifles Only range in Kingsville, Texas. The Brawl is a one-of-a-kind physical and mental challenge that tests shooters’ abilities to read wind, figure ballistics, and adapt to difficult shooting scenarios. There is even a helicopter stage.

Helicopter Stage at 2014 Bushnell Brawl in Texas:

Shooting from a helicopter, shooting off of a wire, and shooting from the physically demanding maze called the Mouse Trap. These are just a few of the unique courses of fire at the Bushnell Brawl, part of the PRS series. Over the course of two days, competitors tackle more than a dozen stages. In addition, Bushnell hosted a special one-day event for the new PRS Production Class. This new division should attract new shooters by limiting the cost of equipment — making PRS competition more affordable.

New PRS Production Division — Lowering the Cost of Entry
The Production Division is a new PRS classification. Under Production Division rules, the rifle must not exceed $2000.00, and rifle + scope combined must not exceed $3000.00. All other accessories, such as bipod, rear bag, and the sling, can be added at the shooter’s own discretion. Even with these cost limits, you can put together a great rig: “There’s a lot of gear out there that’s not that expensive,” says Production Division Match Director Jacob Bynum. For example, you can get the new Tikka T3X TAC A1 in 6.5 Creedmoor for $1798.00.

Scrambling Eggs at 616 Yards with 6mmBRX

6mm BRX egg shoot

Can you hit an egg at 600+ yards? We mean hit it reliably — not just by luck. To do that you’ll need good shooting skills and a very accurate rifle. How accurate? Well, a chicken egg is, on average, 2 1/4 inches (57 mm) long and 1 3/4 inches (44.5 mm) in diameter. That means to hit an egg (on demand) at 600 yards, you’ll need a rifle capable of 1/3-MOA accuracy (or better). Forum member DukeDuke has such a gun, and he demonstrated its egg-busting prowess in this short video. DukeDuke’s rifle is chambered in 6BRX (a 30° 6BR Improved) and it’s loaded with DTAC 115gr bullets pushed by Alliant Reloder 17. In the video, the eggs are placed on top of poles set 616 yards from the firing line.

As you can see in the video, that’s a heck of a nice shooting range where DukeDuke scrambled those eggs at 616 yards. The range is situated just outside of Lake Jackson, Texas. As for the gun… the action is a Rem 700 SA BDL, blueprinted and bedded in a Rem/HS Precision PSS stock. The 31″ barrel is 1:8″-twist Broughton. The “P3″ on the barrel stands for Porter’s Precision Products, Lake Jackson, TX. The rifle was built by Kenneth Porter. The load was 33.5 grains of RL-17 at 2950 fps, with 115gr DTAC bullets touching the lands. Cartridge OAL is 2.400″.
