We know our readers like accurate rifles — the more accurate the better. You guys also love really great craftsmanship and state-of-the art componentry. To satisfy that lust for amazing, accurate rifles, we’re starting a new feature — Sunday GunDay. We’ll try to do this a couple Sundays a month, provided we have some great candidates. For our first Sunday GunDay feature, we are presenting a stunning .284 Win F-Open match rifle owned by David Christian of Team Borden/Brux/Lapua. This impressive rig is as good as it gets in the F-Open game. The write-up is by David’s friend, Forum member F-Class John.
Tips For Competitors from David Christian
1. Tracking is Really Important. I learned this lesson from Bill Brown. Make sure your rifle is tracking exactly on your bags. If you slide the gun back and forth and it does not line up on your original aim point, something is out of alignment with you rear bag or mat and needs to be adjusted.
2. Wind Calls — Be Brave. Don’t be timid with your wind calls. It is better to err with a slight over-correction, rather than miss a change entirely.
3. More Data is Good. Keep track of as much data as you can so that you can learn from it. For example I shoot as much as I can with my chrono and track my load speeds so that I can tell if I am drifting out of my node.
David Christian’s .284 Win F-Open Rig
Report by F-Class John
Here’s match rifle that’s as handsome as it is effective (and accurate!). In its first-ever tournament, this impressive rig took 8th place overall in F-Open at the 2019 Berger Southwest Nationals. This .284 Win hammer was wielded by David Christian, the newest member of Team Borden/Brux/Lapua. David built this .284 Winchester around a Borden BRMXD action with black PVD coating and a Jewell BR trigger. What I found fascinating is that David had built all of this before ever being approached for the team. When I asked him how that worked out, he simply said he picked the components he liked the best and knew would do the job. It was just the universe in action that he’s now on the team that matches his gear and he’s certainly not complaining that he gets to represent them now.
David uses a custom-contour 32″-long Brux 1:8.5″-twist barrel that tapers from 1.35” to 1.25” because he likes the extra stability and weight it brings. It’s all mounted in an amazingly-crafted Cerus Stock (Speedy Gonzales “Spear of Destiny” design). While Will McCloskey built the stock, it was finished to perfection by Devin Wiggett and mounted by Terry Wright of Right Rifle in Oregon. You might also notice that the buttstock features a R.A.D. recoil system which adds the final touch to the system.
Stunning Laminated Maple/Cherry/Walnut/Wenge Cerus Stock
When asked what people comment on when they see his gun, David says it’s the stock, hands down. Having handled this gun myself, I have to agree and believe me when I say the pictures don’t do it justice. The exterior forearms are torrified Maple while the core is made up of Brazilian Cherry, Walnut, and African Wenge wood. It makes for an ultra-strong stock with stunning beauty to match.
David currently tops this beauty with a Kahles K1050 10-50x56mm scope featuring the MOAK reticle. David really likes the 20 MOA per revolution dial as well as the top-mounted parallax adjustment. This is especially helpful for him as David shoots left-handed. Most scopes have a left-side parallax knob which is difficult for him to use during a match.
You can’t have a rifle this good-looking and functional without riding on the right gear. David uses a Protektor DR Bag and a SEB Special Edition NEO coaxial front rest. All told it took nearly six months to get all the parts delivered and assembled but he looks at that as a short term loss and a long term gain. Using Erik Cortina’s load development methods with Berger 180gr Hybrid Target or 184gr Hybrid Target bullets and quality Lapua brass, David has achieved some amazing results. Here’s a representative target from a recent match. That’s mighty fine shooting!
If you want to “hit the ground running” in the F-Open game, this wouldn’t be bad setup to emulate and if you see David at a match, he’s always more than happy to talk to you about it.

 A 7mm Snake for Santiago
Our friend Dennis Santiago has a reptilian rig in his arsenal. It’s actually an Eliseo R1 single-shot tubegun chambered in .284 Winchester. The eye-catching aspect of Santiago’s .284 bolt-gun is the snakeskin dip job on the exterior. This really creates a distinctive look. Dennis tells us: “It was Gary Eliseo’s idea to try a water-transfer printing finish for this rifle. There are many patterns to choose from — this is the WTP-260 Snakeskin Illusion-Fall Copper from WaterTransferPrinting.com. For a single shot LR gun, I figured something on the bright side would be interesting and pick up less heat from the sun in the summer.”
Dennis uses this eye-catching rifle in prone matches, where a single shot works fine. He says: “Underneath the hood, it’s a Rem 700 Long Action, chambered in .284 Win. Yes it’s a single shot! I don’t need anything else for a prone gun. Nothing to get in the way of building the perfect position.”
Dennis says: “Length of pull, offset and cast initially set the same as my similar RTS .308. My gun, my body dimensions.”
R1 Testing with Advanced Electronic Shot-Plotting System
Now that winter is here, Dennis plans to do some serious load development with this rifle: “I acquired a new ShotMarker electronic target system. I’ll be using that to test a variety of powders and bullets.” Dennis has previously loaded his .284 Win R1 with Hodgdon H4831 powder, but he hopes to test alternatives from Alliant and IMR as well. There are many interesting 7mm bullet options, such as Sierra’s impressive, factory-pointed 183gr MatchKing with 0.707 G1 BC, and Berger’s new 184gr F-Open Target Hybrid with 0.695 G1 BC.
The ShotMarker is a unique 8-sensor acoustic electronic target that instantly plots shot locations and transmits the data via WiFi to a mobile device. Dennis is eager to try his new Shot-Marker. The system can measure group size, velocity, and SD. The Shot-Marker App can then store your strings for later review, add notes to the target, and export data to spreadsheets.
A FFP 6-24x50mm Sightron Rides on Top
The optic is a Sightron 6-24x50mm, FFP MOA-2. Dennis reports: “I looked at many scopes (within my determined price range), and this is the one that had the best combination of features for for this gun’s particular application. The sight line sits about 3 inches above bore line on these guns. It’s been leveled, bore-sighted and pre-dialed for a 200-yard estimated zero for the ammo I plan to use. Those are Gen II A.R.M.S. rings. Super easy to tailor to different rail widths. Same rock-steady steel performance.”

That fancy front rest is a Farley with custom polished aluminum magnum base, John Loh top, and upgraded large-diameter “Speed Demon Wheel” elevation adjustment. The barrel is a 1:8.75″-twist Bartlein fitted with Ralph Stewart 3-Disk rotary tuner. The 32″-long tube tapers from 1.250″ to 1.0″ diameter. Speedy prefers to have a bit of taper in barrels even when weight is not a factor.
The F-Class World Championships take place next month at the Connaught Ranges in Ontario, Canada. Here’s something special gunsmith Speedy Gonzales put together for F-Open shooter Brett Solomon. Christened the “Little Red Devil” by Speedy, this ruby red, flame maple-stocked beauty is chambered in .284 Winchester. It features a Melonited BAT 3LL action with two bolts (regular and magnum bolt face). The stock is the Speedy “Spear of Destiny” design crafted by Will McCloskey. These handsome McCloskey stocks are milled with advanced CNC machines, allowing ultra-precise tolerances for improved tracking and perfect geometry.
Speedy tell us: “Wish I could say the pictures do it justice. It is ten times nicer looking in real life. Bret will be rubbing on it for hours when it arrives…”
Torrefied Wood from Yamaha
This wood is very special — the flame maple was sourced from Yamaha which used a torrefaction process to stabilize the wood and prevent warping. Yamaha’s proprietary ARE process was developed by Yamaha for musical instruments. Speedy explained that Yamaha uses heat and pressure (we think) to stabilize the wood and dampen vibrations. During torrefaction, the sap in the wood actually crystallizes.
For this rifle build, the torrefied wood blank was CNC-milled by Will McCloskey to “best-in-industry” tolerances. Then Speedy did the inletting, fit the triggerguard, action pillars, butt-plate assembly, and other details. Then Speedy removed the metal parts and shipped the stock to Lee Garver, a noted guitar painter. Garver applied a special red-tone polyester finish. This is a very hard, yet glossy finish that makes the stock “pretty nearly scratch-proof” according to Speedy.
The rifle sports one of Ken Rucker’s new F-Class Bump-Buster Gold recoil reducers. This new system is optimized for prone shooting and works with minimal touch/hold shooting styles.
This video shows the CNC-Milling process with another Speedy stock, the adjustable-comb version of his “Spear of Destiny” design:
The BAT 3LL action comes with two (2) complete bolts, one with standard bolt face, the other with a magnum bolt face.
When One Stunning Rifle Is Not Enough…
If you aren’t yet totally consumed with envy, consider this. Brett Solomon has invested in THREE more Speedy-built rifles like this red wonder. There’s a TAN (natural finish) rimfire training rig that’s complete, and Speedy’s now working on a GREEN .284 Win “spare”, plus a BLUE dedicated Magnum rig. The tan, green, and blue rigs for Brett will have similar stocks, with “all the bells and whistles” just like the “Little Red Devil”. Brett is currently using the tan-stocked rimfire rig for training — getting lots of “trigger time” without burning out his precious centerfire match barrels.

Cartridge Choices for F-Class Competition
By Emil Kovan
Kovan Match Rifles LLC, www.matchrifles.com
There are hundreds of cartridge types capable of winning in F-Open. For F-TR you can shoot either the .223 Rem or .308 Win, but you have many load options. This article will focus on proven choices, currently used by the top F-Class shooters in the world. Our discussion will analyze cartridge selection based on the four different F-Class sub-disciplines: Open Mid-Range, Open Long-Range, F-TR Mid-Range, and F-TR Long Range.
Click image to view full-screen photo.
Mid-Range F-Open Cartridges
For starters, a .300 WSM is certainly capable of winning mid-range matches but it is not ideal. So what is ideal, and why? F-Class Mid-Range matches usually are usually shot at 300, 500, or 600 yards — or all three. At those distances the 6mm and 6.5mm cartridges rule. In moderate conditions, the 6mm Dasher is unbeatable. Its low recoil along with its super grouping ability and good ballistics make it my number one choice for Mid-Range.
Best bullets for the 6mm Dasher are: Vapor Trail 103gr, Berger 105 Hybrid, 108 BT, and 105 VLD (hunting). Best powders are: Varget, H4895, and Reloder 15.
Choices for Mid-Range in Tougher Conditions:
We all know that conditions are not always “moderate” that’s why something a little bit bigger will save you a “Nine” or two. The 6.5X47 Lapua was designed for 300-meter competition, but as soon as it was released, it was adopted by F-Class, benchrest, and tactical shooters. It offers great ballistics with very low recoil and big “accuracy window”. Lapua makes great brass for it (no surprise there) and Berger makes great bullets: 130gr VLD, 140gr VLD, 140gr Hybrids. Best powders in most barrels are Varget and H4350, I don’t use double-based powders such as Reloder 17 and the Vihtavuori N500 series because of their unpredictable performance day to day (greater temp sensitivity).
The 6.5X47 Lapua necked down to 6mm is also a great option for mid range matches. I was able to easily get 3200 fps with 105 hybrids and H4350.
Choice for Long-Range F-Open Competition
In Long-Range F-Open Class (out to 1000 yards), the big, high-BC bullets rule. If I had to pick one cartridge for F-Class (both mid- and long-range) I would pick the .284 Winchester or one of its variants. The .284 Win is currently dominating in F-Open competition. It offers great barrel life, it is super-easy to tune and its recoil is very manageable. The best bullets for it by far (in my opinion), are the Berger 180 Hybrids. But Sierra’s new 183gr MK bullet (with factory-uniformed meplats) seems to perform very well as does the Berger 180 VLD. Best powders for the .284 Win are H4350 and H4831SC.
Long-Range Only F-Open Cartridge
As much as I like the .284 Win, for long-range competitions I like the .300 WSM even more. If you look at a .300 WSM and a 6mm Dasher side by side, they appear almost identical in geometry — the .300 WSM looks like an “super-sized” Dasher. Both cartridges are currently the “darlings” of long-range benchrest due to their extraordinary grouping ability and huge “node’’ windows. Big accuracy windows allow loads to perform well in different conditions and geographical locations. That’s obviously very important if you travel to compete. The .300 WSM loaded with Berger 215gr or 230gr Hybrids is very tough to beat at long range, and it is currently my number one choice.
The 7mm RSAUM is another outstanding long-range round. It resembles a 6BR on steroids and it is almost as easy to tune. Best bullets for it are Berger 180gr Hybrids, 195gr EOLs, and Sierra’s 183gr MatchKing. Best powders for the 7mm RSAUM are: H4350, H4831SC, and VV N160.
Top Caliber/Bullet Combos for F-TR
In F-TR competition, the choice is clear — a .308 Win throated for Berger 185gr BTLRs and 200gr Hybrids will win in mid-range AND long-range comps. Many championships have been won, and many records set with those two bullets in the .308 Win. To quote Danny Biggs (a two times FTR National Champion) “The 185 BTLR is the best bullet for .308 Win ever made”.
The Berger 215gr Hybrids have been used to win many competitions including recently the 2015 F-Class Nationals. Bryan Litz won both the Mid-Range and Long-Range 2015 Championships using 215s. Bryan’s rifle is shown below:
I recommend chambers throated for the 185/200 grain projectiles over the 215/230 grain bullets. The reason is that if you have your barrel throated out for the 215s or the 230s, you could have a “slow” barrel and max out on pressure before the desired velocity is reached. Optimum freebore for the 230s is too long for the 185/200s, so you would be limited to using only 215/230gr bullets in that barrel.Furthermore, the recoil increase with heavier bullets is substantial, causing the rifle to be more difficult to shoot.
 .223 Rem — Not A Competitive Option
I would stay away from the .223 Remington. On paper the 90gr VLD will shoot inside most .308 Win loads even at a 1000 yards. But in reality, on average, the .223 Rem, regardless of what powder/bullet combo is used, cannot compete with the .308 Win. [Editor: The equipment lists at major F-TR matches will confirm Kovan’s conclusion here.]
Conclusion (and Other Options)
This article covers only the (currently) most popular cartridge/bullet combos for F-Class (F-Open and F-TR). As I said in the beginning, many cartridge types are capable of winning but are not listed due to their low popularity, case design, or lack of quality components. All of the above information is based on my personal experience and it is meant to help new shooters choose the right cartridges for F-Class matches. Thanks for reading and good luck — Emil Kovan

If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane, an improved version of the .284 Winchester. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel!
Gun builder Ryan Pierce of Piercision Rifles explains:
Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. This was the first five rounds through it after I cleaned it after the last match. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.
Ya, I figured why not I had some old barrels laying around so I just chopped 2″ off the back and 1″ off the front and chambered it up as a Shehane. Had 1000 pieces to fireform and didn’t want to do all that on a brand new barrel.
My fireform loads are going 2765 FPS. I have a 29″ barrel also though since it’s a setback. Once you get it formed I would push it faster than that or I wouldn’t even bother with the Shehane. My old straight .284 load at 2890 fps had ES spread in single digits for 10 shots. I figured if I get it up to 2935-2950 fps that will be a point or two saved in a several day match.
Fellow .284 Shehane shooter Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.

Emil Kovan is one of the top F-Class shooters in the world. He won the 2014 United States F-Open Championship. Earlier this month Emil finished second in F-Open Division at the 2016 Canadian National F-Class Championship in Ontario. Emil actually tied Open-class winner Shiraz Balolia for overall score AND “V”-count, but Emil was awarded second on the tie-breaker.
The Anatomy of a Modern F-Class Open Rifle
Report by Emil Kovan
Kovan Match Rifles LLC, www.matchrifles.com
“What are the best components for an F-Open class rifle, and why?” That’s a question that I get asked all the time and will try to answer in this article. Two months ago, I was contacted by Duane, a gentleman I met at the 2015 F-Class Nationals. He was interested in building a rifle with the new Master Class Low Profile F-Open Stock, created by Carl Bernosky and Alex Sitman of Master Class Stocks.
I have known Alex Sitman for many years, and use his stocks exclusively, but was not very familiar with his new Low Profile F-Open stock. After a brief conversation with Alex, I placed an order, and had the stock inletted and bedded at my shop in a month. My first impression was “Wow that’s a long stock” — the forearm is significantly longer than on the original Master Class F-Class prone stock. I bolted the barreled action in, and squeezed the end of the forearm and barrel together, the stock flexed a little bit, but not as much as other designs that I have tested. I think that’s due to having “more meat” in the receiver area. The full stock depth continues farther forward that on some other “low profile” designs. That makes the stock stiffer in the vertical plane, reducing the hinging effect forward of the action. The stock was finished in gloss black per the customer’s request. Interestingly, I found that the multiple layers of paint and clearcoat stiffened the stock up quite a bit.
CLICK IMAGE below for full-screen version
Low Center of Gravity Tames Torque
Compared to the original Master Class F-Open stock, the barrel sits about an inch lower. Lower center of gravity equals less torque, and that is very important when shooting heavy bullets in fast twist barrels. Another significant improvement is that the toe of the stock is flat and parallel to the forearm. I added a 3/4″ track rail in the rear, and milled the underside of the fore-end to create two parallel “rails” in the front to help the stock track better.
One of the biggest reasons why I like Master Class stocks, is the pistol grip. I don’t shoot “free recoil” and a comfortable pistol grip is super important to me when selecting a stock. The new Master Class Low Profile stock shares the same grip as the old model. This allows the stock to accommodate either a “hard hold” style or a more free-recoil style of shooting — whatever the rifle’s owner prefers. This design versatility is one reason I recommend Master Class stocks. Shooters may experiment with either shooting style to find what suits them best.
Cartridge Choice — A 40° .284 Win Improved
Duane decided to have the barrel chambered for my 284 KMR IMP (Improved) wildcat. What is .284 KMR IMP and why choose it over the straight .284 Winchester? Improved by definition means “made better”, I took a great cartridge, and modified it to increase capacity, reduce pressure, and increase brass life.
There are many “improved” variants of the original .284 Winchester: 7mm Walker, .284 Shehane, .284 Ackley and so on. My version, the 284 KMR IMP, shares the .010″ blown-out sidewalls of the .284 Shehane, but I have further increased the case capacity by changing the shoulder angle from 35 to 40 degrees. The 284 KMR IMP allows you to almost match magnum cartridge velocity in a standard-bolt-face action. If you want to run 180gr-class 7mm bullets over 2900 FPS, it is cheaper and more convenient to have a barrel chambered in 284 KMR IMP than to spend $650 for a magnum bolt.
Tuning Loads for the .284 Win Improved Cartridges
The 284 KMR IMP seems to have two nodes, one around 2820 fps and other at 2940 fps. My match load clocks at 2935 fps with single-digit ES. Note –I selected that load based on accuracy, NOT raw speed. A lot of novice (or hard-headed) shooters make the mistake to push their cartridges to the max, and disregard more accurate loads at lower velocity.
The sport of F-Class is rapidly growing, and the equipment used is improving constantly. I remember that only few years ago, an F-Open rifle that could shoot sub-one-inch of vertical at 300 yards was considered competitive. Now, we are pursuing sub-one-inch vertical at 600 yards! It takes a great rifle to approach that goal, but it is also up to the shooter to learn and experiment as much as possible in order to achieve success.
Dies for an Improved .284 Win Cartridge
One of the biggest challenges in campaigning a wildcat cartridge has been obtaining great dies. When searching for custom dies, it almost seems like that the odds are stacked against us. The most common problem is wait-time — custom die orders can take months to be completed. Also, most custom die makers want you to send them two or three cases, each fire-formed three times. I find that funny because if could somehow properly size the cases for three fire-forming cycles, I would not need a sizing die.
Custom-made dies should size the case just right, but sometimes the die’s internal dimensions are slightly off, and this leads to problem number two: dies sizing too much (or even worse) too little. I had a one “custom” die that would not size the bottom of the case enough. This made the extraction of fired cases very difficult. I feel that the best option (if available) for shooters interested in wildcat chambers is to have their gunsmiths make the dies. I offer that die-making service in addition to barrel chambering.
BAT Machine “M” Action
Duane decided to use a BAT M action for this rifle, and I think that he could not have made a better choice. We are blessed with many good match-quality receivers: Barnard, BAT, Borden, Kelbly, Nesika, and Stiller just to mention a few. These are all very well-made and suitable for F-Class. Among BAT Machine Co.actions, I like BAT models M, MB, and 3LL best. I prefer these because because of their size (large bedding footprint) smoothness, timing, options available, and last but not least visual appearance.
Trigger: I recommend and use Jewell triggers. Other good options are: Kelbly, CG Jackson (good 2-Stage) Anschutz (best 2-Stage for Bat and Kelbly actions), Bix’N Andy, and David Tubb.
Barrel: Duane made another good choice here. He decided to go with a Brux 1:8.5″-twist, 4-groove cut-rifled barrel. If you look at the F-Class and Long Range benchrest equipment lists, you will see that cut-rifled barrels are currently dominating. Many records have been shot with both button-rifled, and cut-rifled barrels. I have shot both, and prefer cut-rifled barrels. I am not saying that button-rifled barrels are not capable of shooting as well as cut-rifled barrels, but on average, in my experience, four out of five cut-rifled barrels (from top makers) will shoot well, vs. three out of five buttoned barrels. YMMV, but this is what I’ve observed.
Brux Barrels is not the only company that produces very accurate cut-rifled barrels. We know that Krieger, Bartlein, Satern, and Hawk Hill Custom all make fine cut-rifled barrels as well.
Scope: Duane’s rifle was fitted with a Nightforce 15-55x52mm Competition scope with DDR-2 reticle. This optic is ultra clear, reasonably lightweight (28 oz.), super reliable, and has 1/8 MOA clicks — what you want for long range F-Class competition. In this 15-55X NF model, I like the DDR-2 reticle best, because fine cross hairs (FCH) are hard to see in heavy mirage. The DDR-2 has a heavier horizontal line, with a center dot. March scopes are also very popular and very well-made.

I am very sad to announce that a good friend (and a brilliant shooter) Jerry Tierney, has passed away at age 77. I have worked on this site for 11 years, and Jerry was one of the most helpful and talented men I’ve met along the way. Though he won many championships, Jerry was a modest man who always was there to help other shooters. I will really miss him. AccurateShooter.com owes a debt of gratitude to Jerry. With his technical expertise, he helped me greatly with my understanding of rifle accuracy. Jerry was small in stature, but big in talent. Rest in Peace Jerry. We’ll miss your smarts, your good humor, and your love for the sport. — Paul McM, Editor in Chief.
Jerry Tierney shot competitively for nearly 50 years and won multiple championships in various rifle disciplines. Fellow shooter Donovan Moran noted: “Jerry was the leading member of the NBRSA ‘Long Range Hall of Fame’ — well deserved! He was a very friendly man, a mentor to the sport, and one of the best Long Range competition shooters there’s ever been.”
With great natural talent and the mind of a scientist, Jerry could win events in ways not thought possible. He is certainly the only man I know who won a Benchrest Championship shooting a prone-type tube gun. He pioneered the .284 Win as an F-Open weapon. A self-declared “iron-sight prone guy”, he competed for many seasons in the full-bore and Palma disciplines, but in the last decade he turned his attention to 600-yard and 1000-yard benchrest and F-Class. He won multiple NBRSA Nationals, due in no small part to superb wind-doping skills and mastery of the “mental game”.
A former computer engineer with IBM, Jerry was an extremely bright guy who took a systematic approach to the sport. He made decisions based on hard data. He did things many shooters once considered radical (such as cleaning his barrels infrequently), but he always had the data to back up his methods. He was a forward thinker who wasn’t afraid to depart from conventional wisdom if he found a better way to do things. For me, Jerry Tierney was an important mentor — he showed me how the “state of the art” could be pushed to higher levels with careful experimentation and a willingness to try new things.
We did a lengthy interview with Jerry way back in 2005, when Jerry won the NBRSA 1000-yard Nationals. That performance helped proved the worth of the .284 Win in 1K competition, a cartridge that now is a leading choice for F-Open. Read this interview carefully — even ten years later, Jerry offers many nuggets of advice that can help with your reloading and shooting:

 Danny Biggs Remembers Jerry Tierney
Past National F-Class Champion Danny Biggs wrote: “Our long-time shooting friend, Jerry Tierney, left the range last night. Jerry was 77 years old, and was overtaken by bad health over the past year…cancer and other ailments. An accomplished Palma Rifle shooter, his home range was the Sacramento Valley Shooting Center, near Sacramento, CA, and, just 16 miles from his front door, outside Plymouth, CA.
Jerry was a frequent contributor to [Rifle Blogs] in past years. In particular, about 7 years ago, he published considerable results of his testing of the Winchester .284 cartridge. This testing convinced several of us to transition from the venerable 6.5-284 to the straight .284 for both long range ‘sling’ and F-Class Open. Jerry’s testing was primarily in the realm of F-Open; wherein, he fell ‘in cahoots’ with a young F-Open shooter, Charles Ballard, who set an F-Class Open National record that stood for many years. (By the way, Incahoots is the name of Jerry’s favorite restaurant in Plymouth, CA, near his home; where I’ve enjoyed many an evening meal with him.)
Many others have contributed to the legacy of the Winchester .284… but, if you happen to be shooting a .284 in F-Open today, you might just give a thought to Jerry at your next trigger-pull. More than likely, you are shooting some of his data.” — Danny Biggs
Forum Member Killshot added:
“I only new Jerry for a few years, as I began shooting F-Class in 2010 — but he always answered my questions, helped me with my first Wildcat chambering and I never, ever, saw or heard of him ‘Big Timing’ anyone. I’ll miss his gap-toothed grin, like he knew something you didn’t. (and probably did!)
We’re better off for knowing him and worse off for not having him around any longer. So, appreciate your friendships and shoot small… Jerry would.”

We first ran this story a couple seasons back. Since they we’ve received many questions about this gun, so we thought we’d give readers another chance to learn about this truly innovative, switch-barrel “convertible” rifle. This gun works for both short-range and long-range benchrest matches.
You interested in a really wild, innovative bench gun that can shoot both short-range and long-range matches? Check out Seb Lambang’s latest “do-it-all” rifle. It’s a switch-barrel rifle combining two very different chamberings: 6 PPC and .284 Winchester. With that caliber combo, Seb’s covered from 100 yards (LV/HV mode) all the way out to 1000 (LR Light Gun mode). But the dual chambering is not the rifle’s only trick feature. Exploiting the new long-range benchrest rules, Seb has fitted a 3″-wide, flat rear metal keel to the buttstock. That counter-balances his 30″-long 7mm barrel, improves tracking, and adds stability. Seb built the stock and smithing was done by Australian gunsmith David Kerr.
Detachable Hammerhead Wing Section Plus Fat-Bottom Keel
To further reduce torque and improve tracking, the stock features an 8″-wide, detachable fore-end fixture. This “hammerhead” fore-end section has extended “wings” on both sides, making the rifle super-stable. The hammerhead unit can be removed, leaving the stock 3″ wide for use in registered benchrest matches where 3″ is the maximum width. The photos below show Seb’s gun in .284 Win Long-Range (LR) Light Gun mode.

In January, during SHOT Show, Bullets.com President Shiraz Balolia inked a contract with Norma to produce ultra-high-quality .284 Winchester and 6mm Dasher brass. This was great news for competitive shooters. The .284 Win is the caliber to beat in F-0pen competition and the 6mm Dasher holds most of the records in the 600-yard benchrest game.
We’ve just learned that the new Norma .284 Win brass is in production and should be available in five to six weeks. Shiraz tells us: “Production is in full swing in Sweden and the picture below shows the very first .284 Win case that came off the line. They [.284 Win cases] are in testing and we expect to have them here in USA by the end of April.”
Bullets.com should start taking pre-orders in the near future. Shiraz explained: “As far as pre-orders for the Norma .284 Win brass go, we are waiting for final pricing. When we have that, we will make the .284 Win brass active on our Bullets.com website and will take orders. Those orders will be shipped in the order they were received.”
NOTE: This is just a QuickDESIGN drawing, NOT the Norma brass blueprint. Dimensions may vary slightly, so do not use this to spec reamers or other tools. Wait until you can measure the actual brass.
What about 6mm Dasher Brass from Norma?
Dasher fans will have to wait a little longer. Shiraz Balolia says: “It may be months for the Dasher brass. We will keep on them, but if I were to guess, it will be late summer 2015″.

Bullets.com has contracted with Norma to produce 1,000,000 pieces of .284 Winchester and 6mm Dasher brass (500,000 of each type). This is big news for competitive shooters. The .284 Win cartridge is a proven winner in F-Class competition and the 6 Dasher is a record-setting mid-range benchrest cartridge. It’s tough to beat the Dasher at 300-600 yards, and the .284 Win is probably the most successful cartridge for F-Open shooters.
Bullets.com President Shiraz Balolia (left) and Norma Managing Director Paul-Erik Toivo “ink the deal”.
Shooters should be excited about these new offerings. Bullets.com’s contract with Norma calls for advanced production methods to make sure the new brass is truly “match-grade” and long-lasting. To ensure that primer pockets stay tight for many firings, the caseheads on the new brass will be double-stamped for improved hardness and strength. Additionally the new brass will go through an additional draw stage to ensure ultra-uniform casewall thickness. With these extra manufacturing steps, this new 6mm Dasher and .284 Win brass should be the best brass Norma has ever produced, as Bullets.com President Shiraz Balolia explains in the video below:
Shiraz Balolia Explains the Qualities of the New Brass
Shiraz reports: “Normally, Norma has about 25 steps of quality control (QC) during the production process of brass. They told us that our first shipments will have almost 30 steps to make sure that the brass is absolutely flawless when it leaves the factory.”

 6mm Dasher without Fire-Forming Hassles
Until now, if you wanted to shoot a Dasher, you had to go through the time-consuming and laborious process of forming brass from the parent 6mmBR Norma case. You had to blow the shoulder forward, either through fire-forming or hydro-forming. Now that’s all changed — you will soon be able to take perfect 6mm Dasher brass out of the box, and “load and shoot”.
The Deal is done. New Norma .284 Win brass will start arriving in the USA in March, 2015, while the new Dasher brass is expected in late summer 2015.
IMPORTANT — The above diagrams were made 4 years ago with QuickDESIGN. They are for illustration purposes ONLY. These are NOT reamer prints, and there may be small differences compared to the Norma .284 Win and 6mm Dasher brass ordered by Bullets.com. Do NOT spec reamers based on the above illustrations. Wait ’til we have the actual Norma brass to measure.

After we posted Erik Cortina’s video featuring the trimming of 7mm Shehane cartridges with a Giraud Power Trimmer, many of our readers asked: “What’s a 7mm Shehane? How does it differ from a standard .284 Winchester?” To answer that question, we’re reprising a “cartridge profile” we ran a couple seasons back. This talks about the qualities of the 7mm Shehane, and includes a reamer print. The 7mm Shehane is an excellent “upgrade” to the .284 Win. The added capacity may not seem like much, but it allows some Shehane shooters to reach a higher, optimal velocity node.
 7mm is the caliber to beat in F-Class Open Division (though many guys are looking hard at the big 30s.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr bullets to competitive velocities. A .284 Improved will shoot well inside a 6.5-284, and you’ll probably get significantly longer barrel life (at least 1800 rounds vs. as little as 1200 for the 6.5mm).
The straight .284 Win is a good cartridge, but in most barrels, it can’t push the 180s at 2900-2950 fps velocity levels*. A lot of barrels will top out at about 2850. That’s where the .284 Shehane comes into play. The .284 Shehane is a slightly modified wildcat that retains the same 35° shoulder as the parent case. However, by blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc. With N560 or Reloder 17 you can go even faster.
Scotland’s Grant Taylor used the .284 Shehane to finish 3rd overall in the 2009 individual F-Class World Championships at Bisley, England. Grant reports: “I have a .284 Shehane and it’s very accurate with superb vertical spreads at 1000 yards. I have to thank Jim Hardy for putting me onto the caliber, it has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”
Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long range round there is — bar none. I (perhaps_ have shot more of this chambering than anyone else, and it has proven better than I ever expected. Here is why:
You have to shoot a 30 Cal magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight 284, the 300 WSM, and the 300 Win Mag with less recoil. The .284 Shehane offers twice the competitive barrel life of the 6.5-284, an easy 2950 fps with H4831 SC, [and it] can run 3000+ with N560 and Reloder 17, which is right there with the 7mm WSM. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”
*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce, who recently set a 450-24X Pending F-Open record, has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s.”

Forum member K.W., aka ‘CigarCop’, has spotlighted his handsome long-range F-Class and Bench Rifle in our Forum’s Show Off Your Bat! thread. This is built with a BAT Multi-Flat action, Brux barrel, and a fiberglass McMillan F-Class stock. As you can see, it’s one handsome rifle. Be sure to click the image below to see the much more impressive wide-screen image!
The smithing was done by Bob Green and CigarCop was full of praise for Bob’s work: “I can’t really say enough about Bob Green, his attention to every detail and his ability to build an awesome shooting rifle… but once again he turned a pile of parts into a masterpiece! This irf was built on a Bat MB Multi-flat in .284 Win with a Brux 1:8.5″ twist barrel. It’s almost identical to my 6.5x47L that [Bob] also built. Once again, thanks Bob!”
Bob Green told us: “There was nothing really unusual about this build — this is the quality we try to maintain on all our guns. The barrel was chambered with the client’s reamer to a min-spec SAAMI .284 Win. The Multi-Flat BAT is pillar-bedded and bolted in, with no extra weight added to the stock. CigarCop provided the nice metal spacers on the buttstock and I polished them up. The finish is plain black but it looks good.”
Based in York, Pennsylvania, Bob Green is one of AccurateShooter.com’s recommended gunsmiths. To learn more about his Bob’s work visit GreensRifles.com, email Bob [at] Greensrifles.com, or call (717) 792-1069.
