This story first ran ten years ago. But to mark our long-standing friendships with shooter Joe Friedrich and chassis builder Gary Eliseo, we wanted to reprise the article for a new decade. Joe’s Eliseo-chassis 6BR rifle delivered some of the most stunning factory ammo accuracy we’ve ever seen, in any rifle, in any caliber.
Amazing Accuracy from 6mmBR Tubegun
What kind of accuracy do you think a tubegun can deliver with factory ammo — during barrel break-in? Perhaps 0.6″ at 100 yards, half-MOA if the conditions are perfect? Well you may want to change your preconceptions about tubeguns — and factory ammo. This Eliseo R5 repeater, smithed by John Pierce with a Pierce CM action and Broughton 5C barrel, shot the Lapua 90gr factory ammo into flat ONEs during the break-in session. A day later, in tricky 8-14 mph winds, the gun nailed a witnessed and software-measured 0.174″ 5-shot group using the 105gr factory ammo. That would be impressive for a “full-race” benchgun with precision handloads. For an across-the-course rifle shooting factory ammo, it’s pretty amazing.
Eliseo Tubegun Shoots in the Ones
This accurate rifle belongs to our friend (and designated expert trigger-puller) Joe Friedrich. During the initial break-in session, since his reloading dies had not yet arrived, Joe decided to start with some Lapua factory-loaded 6BR ammo he had on hand. After doing a few two-shot-and-clean cycles (with patches and nylon brush), Joe decided to try a 3-round group just to see if the Broughton barrel had some potential. To his astonishment, the Eliseo R5 put three rounds in 0.100″ (photo below left). Joe then cleaned the barrel again, shot a couple foulers and tried a 4-shot group. The results were just as stunning — 4 shots in a mere 0.104″ but three in virtually one hole (photo below right).
You Can’t Believe How This Gun Shoots
Joe called your Editor and said “You can’t believe how this gun shoots with factory ammo!”. So we arranged a photo session for the next afternoon, where I could verify the rifle’s accuracy. Well it turned out the conditions were way more challenging than when Joe broke in the barrel the day before. Winds were running 8-14 mph and were swinging through 180 degrees half-way down the range. Joe fired a few 90s through the Oehler chronograph at my request, then opened a box of Lapua 105gr factory ammo. It took about four rounds for the barrel to settle in after being cleaned the night before. Then Joe got serious, and with your Editor looking over his shoulder, he drilled a 0.174″ five-shot group in switching winds, doping every shot. Joe felt the gun could have shot tighter but he missed one wind call.
Serious Accuracy with a Multi-Purpose Rifle
So there you have it — a tubegun that shoots in the ones with factory ammo. Joe says that, at least with the 90s, the Elesio R5 shoots as well as his 6 PPC. Joe stressed that “steering the tubegun is hard work. You really have to concentrate compared to a purpose-built bench gun like my PPC. With the tubegun, everything has to be perfect on every shot — hand position, cheek position, stock position in the bag. If you’re off just a little bit, it’s easy to steer the gun the wrong way and send a shot out of the group.”
Accuracy Great But Fouling Heavy and ES Could Be Better
Have there been any negatives to Joe’s 6BR tubegun experiment so far? Well, the Broughton 5C barrel, while phenomenally accurate, shows signs of being a bad fouler. Copper built up pretty quickly over the first 25 rounds or so. We saw best accuracy with a recently-cleaned barrel. Hopefully the fouling will lessen as the barrel polishes in with use. And the canted land barrel is slower than average with the factory ammo. Lapua rates its 90gr naked-bullet ammo at 2950 fps with a 26″ tube. In Joe’s 27.5″ barrel we only averaged 2901 fps. With the 105gr factory ammo, which is rated at 2790 fps, we averaged just 2694 fps. That’s quite disappointing. Also the ES on the factory ammo, slightly over 50 fps for both bullet types, wasn’t particularly good. Still, the overall results were stunning. This gun shoots better than many long-range benchrest rifles running carefully-developed handloads — and it does that with factory ammo, right out of the box.
Joe Friedrich is a superb benchrest shooter, who has won many matches and set National Records in ARA rimfire benchrest competition. Here is Joe with “Sweet Pea”, his favorite .22 LR rimfire rig. With over 100,000 rounds through the Benchmark barrel, this well-worn rifle set an ARA 4-target Aggregate record! READ about Sweat Pea Record HERE.

With the 6mm Dasher cartridge becoming popular with PRS/NRL competitors as well as the benchrest crowd, we thought it was time to re-visit a special rifle chambered for the 6mm Dasher wildcat. This gun has a great story behind it. Forum member Bob A. (aka “Killshot”) used his “Forum Classifieds Special” to beat all comers in the F-Class Division in the American-Canadian Match and the Long Range Regional Match in 2013 in Sacramento, CA.
Bob’s 6mm Dasher sports a blue-printed Rem 700 action. Who says you need a high-dollar custom action to run with the big dogs? In fact, this same gun, built with components sourced from AccurateShooter Forum Classified Ads, set a Sacramento F-Class range record of 200-17X a few years back. In this story, Bob talks about the build, and he explains his methods for loading ultra-accurate Dasher ammo.
Bob’s Budget-Build Dasher F-Classer
I wanted to build a proper rifle for F-Open but needed to keep it simple and, well, cheap. I found a solid “base” to build on in the form of a Dave Bruno-built, “pre-owned” 6-6.5×47 Lapua that I located in the AccurateShooter Forum classifieds in late 2011. The base action was a trued and blue-printed Remington 700 receiver circa 1971 with a spiral-fluted bolt. It was in a Shehane ST1000 stock painted sky blue and had a Jewell 1.5-oz BR trigger. I sent the bolt to Greg Tannel (Gretanrifles.com) to have the firing pin hole bushed and sleeved, the ejector removed and the hole filled and the face trued. I upgraded to Tannel’s Light Steel firing pin assembly while it was out.
Having the working bits completed, I needed a barrel. So I went to the AccurateShooter classifieds again and found a 1:8″-twist, 30″ x 1.25″ (diam.) Bartlein with a 0.236″-land bore. I called Dave Kiff and explained my pursuit and he recommended his PT&G “world record” 6 Dasher reamer (.2704″ no-turn neck and .104″ freebore). A month or so later the reamer and gauges arrived.
I had the barrel chambered by Marc Soulie of Spartan Precision Rifles (510-755-5293, Concord, CA). Marc is a great builder and I’m pleased to call him a friend.
The rifle got its good looks from a Pennsylvania artist named Kenny Prahl. His Prahl Designs shop (724-478-2538) added the white ghost-flames over the existing sky blue metallic paint.
Looks Great, Shoots Better
Fire-forming showed great promise — ten-shot groups of half an inch at 200 yards were typical. I lost only one case to a split neck and the “blow lengths” are good and consistent. This was followed up with load development which saw 100-yard, five-shot groups in the .1s and .2s as the rifle showed its preference for Reloder 15 over Varget powder, and for CCI 450s over all other primers. The bullet of choice was the ever-popular Berger 105gr Hybrid Target.
In February 2012 I began shooting the Dasher in monthly club matches at the Sacramento Valley Shooting Center, the home range of a number of excellent F-Class, Benchrest and High Power shooters. Using a Farley Coaxial rest up front (also picked up from a WTB ad on AccurateShooter’s Forum) and an Edgewood bag in the back, I gradually improved my gun-handling to the point where I could shoot a respectable score. This was very different from the bipod shooting I’d done in the past in F/TR.
Dasher Loading Tips
My chamber is set up for blue box Lapua 6mmBR brass. My case preparation is straight-forward. I fire-form with virgin cases right out of the box. I don’t size them but I will give the primer holes a good look and clean up the flash hole with a .058″ bit in a pin vise. To fire-form, I seat a Berger 108gr BT .030″ into the lands over a standard 6mmBR load of Varget.
For match loads, I use Alliant Reloder 15. While Varget is less sensitive to temp changes, RL15 has given me lower extreme spreads and better long range control. [Bob acknowledges that every barrel is unique, so a different powder, such as H4895 might work better for you.]
I clean my fired cases with stainless steel media in a Thumler’s rotary tumbler after every firing. I anneal after every other firing using a Bench-Source machine which is very well made and easy to operate. I use a Whidden full length bushing die with Redding bushings for sizing.
After sizing, I chamfer the inside of the neck with the K&M tool which has a pilot rod centered in the flash hole. Then I’ll give the neck and mouth a “once over” with some 0000 steel wool. I finish loading off with a Redding Competition Seating Die with the micrometer top.
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Seating Depth Considerations
With fire-formed brass, the junction of the bullet’s bearing surface and boat-tail is above the neck/shoulder junction of the case, so I have no issues with donuts. You can see how a loaded round looks in the photo at left. For occasional trimming, I use a very nice little Possum Hollow trimmer that indexes on the case shoulder.

You don’t hear much about PacNor barrels in long-range competition, but FORUM member Wes J (aka P1ZombieKiller), proved that they can shoot “lights-out” in a rig assembled by a talented gunsmith. A few seasons back, Wes decided to upgrade a 6mmBR for mid-range benchrest and varmint matches. Wes tells us: “Since I restocked my 6BR … I have not had a chance to shoot it much since I have been playing the 100-200 game. I decided to take it out and do some playing at 500 yards. I have to give some serious props to my buddy (and fellow FORUM member) ‘PREACHER’ who did the chambering and barrel work for me. He can certainly make a gun shoot good. The barrel is a PacNor 1:8″ twist. My load was 105gr Berger VLDs pushed by 29.6 grains of Varget.” The five-round, 500-yard group shot by Wes J with his 6BR, measured just 1.240″, as measured by OnTarget software. Now that’s one accurate rig!
Five by Five — 5-Shot Group at 500 Yards, 1.240″, 0.237 MOA
This Editor knows something about the potential of a PacNor barrel. I have a 3-groove stainless PacNor SuperMatch on a Savage-actioned 6BR. This barrel shoots honest quarter-MOA in calm conditions, and it cleans up super-easy. The interior finish is so good, I’ve never had to brush the bore or use abrasives, and after 750 rounds it shoots as well as ever. I attribute the easy cleaning to the fact the lands in a PacNor 3-groove are wide and flat, so they are gentle on bullet jackets. I think accuracy is helped by the fact that my PacNor runs on the tight side (0.236 land dimension) with a good amount of choke. That works well with the 105gr Lapua Scenars and 103gr Spencers I like to shoot. You can read more about my rifle, nick-named the “Poor Man’s Hammer”, in this Feature Article from our archives. On one particularly calm day, in the hands of my friend (and ace trigger-puller) Joe Friedrich, the Poor Mans’ Hammer put 3 shots in under 0.200″ (measured center to center) at TWO Hundred yards. If you get a good one, PacNor three-grooves can definitely shoot.
Target Measurement with OnTarget Software
We used OnTarget software to measure the 5-shot group in the target above. This easy-to-use software is very repeatable, once you get a feel for plotting the shots. The latest On Target v2.25 Precision Calculator is FREE for a 15-day evaluation period. If you like it (and you will, trust us) there’s a modest $11.99 registration fee to activate the program. In addition to group size (in inches), OnTarget plots distance to aiming point, and the software automatically calculates the group’s vertical height, horizontal dispersion, average to center (ATC), and group size in MOA.
You can run a measurement on a scanned target or a photo of a target. You’ll need some known reference to set the scale correctly. The target above had a one-inch grid so it was easy to set the scale. Once you’ve set the scale and selected bullet diameter and target distance, you simply position the small circles over each bullet hole and the OnTarget software calculates everything automatically, displaying the data in a data box superimposed over the target image. To learn more about OnTarget Software, read AccurateShooter.com’s OnTarget Product Review. This article covers all the basics as well as some advanced “power user” tips. NOTE: Since the review was written, On Target has updated the software, and the free version now has a time limit.

You can benefit from these precision mandrels, trust us…
Controlling cartridge neck tension is a critical aspect of accurate reloading. A very small change in the amount of grip on the bullet can actually have a noticeable effect on accuracy (and group size). You can tune neck tension with different size bushings used with FL-sizing or neck-sizing dies. You can also adjust neck “grip” by annealing your brass, or turning your necks for reduced neck-wall thickness.
But perhaps the most precise way to tune neck grip on the bullet is to use Precision Expander Mandrels. Many top shooters size their case necks down pretty far with a full-length sizing die then use a precision neck mandrel as a final step. This expands the neck back to the precisely-desired neck diameter. Because you are working from the “inside out”, variances in neck-wall thickness become less important. This also ensures you have a perfectly-round internal neck geometry for seating your bullet. (Yes, unfortunately some neck bushings are not perfectly round inside.)
For guys who want ultra-precise control over neck tension (and “grip” on the bullet), 21st Century Shooting now offers Precision Expander Mandrels in .0005 (one-half thousandth) increments. These will be available for most popular match calibers including: .224, 6mm, .25, 6.5mm, .270, 7mm, .308, and .338 calibers. These mandrels cost $17.99 each, or you can get a complete set of nine mandrels in .0005 increments (for one caliber) for $144.99. Listed below are the nine 6mm mandrels:
John Perkins, owner of 21st Century tells us: “Finally! We have our expander mandrels up and ready to order on our website here: http://www.xxicsi.com/expander-mandrels.html.” This is a big deal. James Crofts, past National F-TR Champion, says “WooHoo — great news!”
To get best results with these precision mandrels, John recommends using the 21st Century Expander Die Body, part #904. Watch video for set-up tips:
John adds: “We are still in the midst of turning all of these so some calibers will ship when they are completed. Should have them all done by end of next week or so! Thanks for your patience while we got these set up and in process!”

“Koenig” (or König) means “king” in German. That is indeed appropriate for Doug Koenig, 18-Time Bianchi Cup winner, who is now starting to conquer the rifle world as well. Koenig, considered by many to be the best action pistol shooter on the planet, proved he’s an ace with rifles too, as he recently won two PRS matches in Production Division. Koenig, Captain of Team Ruger, was shooting a Ruger Precision Rifle (RPR), chambered in 6mm Creedmoor. Notably, Production Division limits rifles to $2000.00 for the gun ($4000.00 overall with scope). You can buy an RPR for around $1100.00 typically ($795.00 at GrabAGun), so Koenig was shooting against competitors with rifles that cost nearly twice as much. That’s impressive.
Koenig Wins Production Class at two Spring PRS Matches
Koenig took home a pair of Production Division titles at this year’s WAR Rifles Shootout and MAP Spring Shootout Precision Rifle Series (PRS) matches.
With a final score of 128.00 and a time of 58.51, team captain Doug Koenig took first place in Production Division at the WAR Rifle Shootout PRS match in Mount Victoria, MD. The WAR Rifle Shootout has a challenging 22-stage course of fire. Along with winning Production Division, Koenig also finished twelfth overall. “The tough course of fire and 15-25 mph winds at the War Rifle match were brutal, but my Precision Rifle, equipped with a Leupold VX-3i LRP and loaded with Hornady ammunition, continued to perform,” said Koenig.
Koenig then secured another Production Division win at the MPA Spring Shootout held at the Arena Training Facility in Blakely, GA with a final score of 173.00 and a time of 58.89. “The MPA match had some long shots out to 800-1356 yards, but my factory rifle got the job done and helped me win my third production class title in a row. That proves you don’t need to spend a fortune to get started in PRS competition.”
According to PRS standards, Production Division rifles are not permitted to be altered or improved in any way from the original factory configuration, and the retail price may not exceed $2,000.
Pre-Fit Barrel Options for the Ruger Precision Rifle
While PRS Production Division competitors like Koenig must stick with factory barrels, there’s no law that says you can’t upgrade your own RPR that’s not used in PRS matches. A barrel swap is probably the single best hardware upgrade you can make. A new custom barrel will improve inherent accuracy and shot-to-shot consistency. Krieger Barrels offers Pre-Fit barrels for the RPR in many popular chamberings including 6XC, 6mm Creedmoor, .243 Win, 6.5 Creedmoor, 6.5 PRC, and .308 Win. These “Drop-In Ready” barrels come finish-chambered and threaded to fit the Ruger action, with factory-spec muzzle threads. The Ruger barrel attachment system allows correct headspace with a pre-chambered barrel. Krieger explains: “Thanks to Ruger’s proprietary barrel nut design, a competent gunsmith will be able to swap out your barrel using an AR15 barrel wrench and proper headspace gauges.”

As the practical/tactical game has evolved, with low recoil and high accuracy becoming ever more important, many top competitors have moved to smaller cartridges such as the 6mm Dasher and its parent, the 6mmBR Norma. These cartridges deliver outstanding accuracy plus good barrel life. However, the “short, fat” 6BR/Dasher design doesn’t feed optimally in magazines designed for the .308 Win family of cases. Yes you can modify your own magazines (Mag Mod HERE), or buy a pricey conversion kit, but now there is a turn-key solution from MDT (Modular Driven Technologies).
MDT’s 6mm BR magazine fits the parent 6mmBR cartridge and all the popular varients including the 6 BRA, 6 Dasher, and 6 BRX. MDT says this new 12-round magazine is a “one-step solution [delivering] smooth, reliable feeding for the most popular rifle cartridges in precision rifle competitions.”
MDT built this AICS-pattern mag for PRS/NRL competitors and anyone wanting to run 6mmBR-family cartridges in mag-fed actions: “The limiting factor for competitors running 6mm BR variants has been feeding. Until now, the only option has been to purchase an AICS-pattern magazine plus an additional kit to make the magazines work with the shorter cartridges. This solution costs upwards of $100 or more and can require additional tuning to work in most rifles.”
The MDT 6mm BR mag has a maximum internal length of 2.580″, which accommodates pretty much any 6mm bullet you’d want to use. These MDT magazines are crafted from quality steel, nitride-treated, then black Cerakote finished inside and out. To reduce friction between cartridge and magazine body, MDT added two internal ribs which provide a smooth transition from double stack to single-feed.
Magazine Conversion — Use .308 Win Mags with Modified Followers
A decade ago we showed our readers how to modify .308 Win magazines to feed the 6mmBR cartridge efficiently. This procedure, explained by Texas gunsmith, Mike Bryant, is easy to do with simple tools. You can modify most standard magazines, both internal-style and detachable style. CLICK HERE for full, step-by-step magazine conversion article.
The basic procedure involves trimming the rear of the magazine, and creating a rear stop with a block from a Remington .223 magazine. Next the .308 Win magazine follower is shortened and beveled. Some guys tweak the feed lips a bit, but this may not be needed. Many of our readers have performed this simple magazine modification and report their rifles feed quite reliably. One reader, who converted a 7mm-08 hunting rig into a 22 Dasher varmint rifle, tells us his modified mag feeds flawlessly.

Here is a very interesting test for the 6 BRA (6mmBR Ackley) cartridge. Forum member James Phillips, a talented long-range benchrest shooter, tested SIX different primer types from three different manufacturers. To help determine vertical dispersion, James set his target out at 500 yards. He then proceeded to shoot 4-shot groups, in order, with each primer type. Velocities were recorded with a chrono. The photo above shows the results. James says: “I’ll retest the best two for accuracy and consistency with 10 shots each”. CLICK HERE for full-screen target photo.
As you can see, ALL the groups are pretty impressive. The smallest groups, 1.253″, was shot with CCI 400 primers. Next best (and very close) was CCI BR4, at 1.275″ for four shots. The “flat line” winner was the Remington 7.5, at upper left. There was almost no vertical.

CARTRIDGE: 6mmBR Ackley, aka 6 BRA. Parent case is 6mmBR Norma. The 6 BRA is fire-formed to create a 40-degree shoulder and less body taper. Capacity is increased, but the neck is longer than a 6mm Dasher. The capacity is enough to get to the 2950+ FPS accuracy node. Some shooters say the 6 BRA is more forgiving than the 6mm Dasher. The 6 BRA is certainly easier to fire-form.
TEST REPORT — Conditions, Shooting Method, Loading Method
Tester James Phillips posted this report in ourShooters’ Forum:
Conditions: The testing was done in the morning over flags. The flags never moved or even twitched. I had as perfect conditions as I could have asked for. It was overcast so no mirage and no wind. There were no other shooters, just me.
Test Procedure: Each shot was precisely shot at my pace and centered the best possible using my Nightforce 15-55X scope. I did not use the round-robin method. Each four-shot group with the same was shot at one time. Then I moved onto the next primer. Everything felt right for each and every shot fired today. Of course I could repeat the test tomorrow and it could be exact opposite of today’s test. We can chase this forever. But [soon] I’m going to test the BR4 and 400 primer… for best accuracy and consistency for 10 shots each.
How Rounds Were Loaded: Each load was weighed to one (1) kernel of powder. So I know that’s as good as I can weigh them. Each bullet seating force was within 1# on my 21st Century hydraulic arbor press.
Previous Initial Load Testing: All groups were shot with 31.1 grains of H4895. During initial load testing I settled in on the Sellier & Bellot primer to finalize everything as it showed more promise over the CCI 450 Magnum I also tried. I was actually surprised to have seen the higher ES and SD from that primer today along with the vertical shown. [Editor: Look carefully — one shot from the CCI 450 is right in the center black diamond, stretching the vertical. By contrast the Rem 7.5 had almost no vertical.]
Velocity and NODE Considerations: I was about 5-6 FPS above what appeared to been my optimum velocity of 2943-2945 FPS, so I’ll test 5 shots of 31.0 and 5 of 31.1 and see what happens from there. I can only assume my velocities where higher due to the higher humidity and of course temps were 5 degrees warmer this morning as well. It wasn’t far off but I noticed it.

Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30 BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6BRA, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
To convert a PPC-boltface action to shoot the bigger cases you can spend a ton of money and buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. This is a relatively simple procedure with the right cutting tool.
Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30 BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.” At right is the lathe form tool Butch uses to rebate the case rims.

There is a special rotating barricade stop, plus a spigot mount on the front of the fore-end which can extend the “wheelbase” between front and rear support. A clever Weight Tuning System allows competitors to adjust gun balance and reduce felt recoil.
State of the Art PRS/NRL Tactical Rifle:
Above is Jon’s Match Rifle shown from summer 2018 with older barrel chambered for 6mm Dasher. These shots were taken during a fire-forming session. John says: “On right (below) is unfired Lapua 6mmBR round. Shoot it and it turns in the case on the left. 6mm Dasher. 25 formed… 975 to go! Alamo Precision Rifles did a great job on this chamber/barrel. It’s won a few matches and placed well in a few others, but after 1800 rounds I think I’ll use the rest of its life as a practice/fireforming barrel.”
Making Brass — 6mmBR loaded round is fire-formed into 6mm Dasher 40° improved case:
Jon Pynch’s Favored Hardware — Curtis Vector Action, Kahles Scope, MPA Comp Chassis
Like many PRS/NRL competitors, Jon uses the MPA Competition Chassis, the most-utilized chassis in the 2016 and 2017 PRS series. The match rifle above sports a Curtis Custom Vector Action with Proof Research barrel. For optics Jon has recently used a Kahles scope in the rock-solid, MPA BA Mount, the #1 Mount used in the PRS in 2017.

Have you ever expanded a .22 or 6mm cartridge all the way up to .30-caliber? If so, you know this can be a difficult procedure that stresses the case necks and neck-shoulder junction. A significant neck-size expansion done in one big jump can increase run-out, cause doughnuts, or worse yet, even split the brass. Therefore you want to proceed in increments, increasing the neck diameter in stages. One smart way to do that is to use a Progressive Press. This article explains how…
The most successful short-range brenchrest-for-score cartridge is the 30 BR. That cartridge, as well as 30 BR variants such as the 30 BRX, all start with the 6mmBR Norma parent cartridge, typically with Lapua 6mmBR brass. To get a nice 30 BR case you want to expand in stages, increasing the inside neck diameter incrementally from .243 to .308.
Darrell Jones of DJ’s Brass Service creates thousands of 30 BR cases each year. He has found a clever way to speed up the process — Darrell uses a Progressive Press. He runs his 6BR brass through four (4) separate Hornady neck-sizing dies with expander mandrels. First there is a .257 die, followed by .264 (6.5mm), .284 (7mm), and then .308. Then a fifth and final K&M die provides one last, slight expansion so the newly-fashioned 30 BR cases perfectly fit the arbor of Darrell’s neck-turning tool.
So to repeat, the case starts as .243 (6mm), then moves in up stages .257, .264, .284, and .308, with a final “finishing” step prior to neck-turning. You can see the expansion in this video, which starts with 6mmBR brass that was first hydro-formed to 6 BRX:
Watch 6mm Cases Expanded to 30-Caliber (6BRX to 30 BRX)
For this demo video, Darrell expands just one case at a time. However, he can also put multiple cases in the progressive — one per station. This takes a little more effort, Darrell says, but the results are still excellent. Darrell tells us: “I do put multiple cases in the progressive to save time. The results are the same — I just wanted to show a single-step process and how it reduces run-out by not stressing the shoulder with one big expansion from 6mm straight to 30 caliber. Doing the operation in multiple stages avoids binds and helps keep the shoulders concentric.”
This same multi-stage procedure can be use to expand other cartridge types. For example you could take .221 Fireball brass in stages up to .308 to create 300 Blackout brass.
Darrell uses caliber-specific, Hornady neck-sizing-only dies with elliptical expanders. Darrell tells us: “The Hornady elliptical expander has a reduced bearing surface that puts less strain on the brass when expanding the necks to the next size.” The fitting at the bottom of the die is the Lock-N-Load die bushing that allows fast die changes.
These particular cases used in the video were first hydro-formed to 6BRX then expanded to 30 BRX before neck turning. DJ’s Brass offers hydro-forming for many popular wildcat cartridges such as 6 PPC, 6mm Dasher, and .284 Shehane.

This story first ran two years ago, but we’re bringing it back to give you guys a smile this summer. Anyone interested in long range accuracy should enjoy this tale of an amazing 800-yard shot by a talented fellow nick-named “Junebug”…
If you were challenged to hit a quarter (i.e. a 25-cent piece) at 800 yards, how would you respond? Well here’s the story of a man who did take that challenge, and proceeded to put a bullet right through the quarter. Forum member Randy D., aka “Birdog”, provides this entertaining account of how his friend Junebug drilled a quarter at 800 yards one Tennessee evening….
Hitting a Quarter at 800 Yards
Story and photos by Birdog
A friend from Indy visited the DOME last summer and returned home telling stories of eggs at 800 yards. He called me back and said his friends did not believe it and wanted to know if I could hit a quarter out at 800 and mail it to him.
Well, I had finally got the time for that challenge last Sunday. My friend Junebug came over and I told him about a new challenge. Junebug is sort of like Voldoc and does not like to be told it can’t be done and set his sights on the quarter. George Clay had his sleeved 700 6XC with 115gr DTACs and Bug had his Diamondback 6 BRDX and 103gr Vapor Trail bullets.
Junebug and Shayne. The quarter was at back fence row on left of photo, 80 yards short of a half-mile
Early to mid-afternoon is not the time for precision 800-yard shooting as the mirage was terrible and the wind was gusting in the high humidity and 95 temps. We took a few shots and got close but no HIT.
I told Junebug to go home and load some shells and come back at 7:00 and I believed we could make it happen. After 7:00 pm is the best time to shoot as the mirage disappears and the wind goes to zero. We met again at 7:00 and had Shayne Halliburton as witness. I took a few shots then Junebug took a few zeroing shots on metal. He was not satisfied with the grouping so he switched brass.
He had some new Hydro-formed brass that had never been fired. He took three sighters on the metal plate and the first two made two little black spots that were touching. Followed with a third shot that almost touched the first two. Darkness was setting in and I told Bug he better try the quarter now. Through my March scope I could barely see the bright quarter and my 1/16th dot completely covered the quarter.
Junebug moved the Diamondback to the quarter and touched her off. A half second later the bright spot on the black paper was gone. I jumped up and did a dance and war hoop and the Bug jumped up for a high five. Now we hoped we could find the quarter. Luckily it jumped out in front of the backer less than five feet and Bug found it immediately.

Dasher Loading Tips
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.

If you haven’t tried Lapua bullets yet you should. The Scenar-L bullets we have tested have proven extremely consistent in weight and base-to-ogive measurement.
