Forum member Skeeter has a 6mm Dasher falling block varmint rifle. The Dasher case is based on the 6mm BR Norma cartridge with the shoulder blown forward about 0.100″ and out to 40°. This gives the Dasher roughly 3.5 grains added capacity compared to the standard 6BR.
Last year, Skeeter needed to form 300 cases for varmint holiday. Skeeter decided to fire-form his brass without bullets. This method avoids barrel wear* and saves on components. There are various ways to do this, but Skeeter chose a method using pistol/shotgun powder, some tissue to hold the powder in place, Cream of Wheat filled to within an 1/8″ of top of the neck, and a “plug” of tissue paper to hold it all in place. Shown below are cases filled with a pistol/shotgun powder charge topped with Cream of Wheat and then a tissue paper plug.
To ensure the case headspaced firmly in his Dasher chamber, Skeeter created a “false shoulder” where the new neck-shoulder junction would be after fire-forming. After chamfering his case mouths, Skeeter necked up all his cases with a 0.257″ mandrel (one caliber oversized). Then he used a bushing neck-sizing die to bring the top half of the neck back down to 0.267″ to fit his 0.269″ chamber. The photo below shows how the false shoulder is created.
After creating the false shoulder, Skeeter chambered the cases in his rifle to ensure he could close the bolt and that he had a good “crush fit” on the false shoulder, ensuring proper headspace. All went well.
The next step was determining the optimal load of pistol powder. Among a variety of powders available, Skeeter chose Hodgdon Titewad as it is relatively inexpensive and burns clean. The goal was to find just the right amount of Titewad that would blow the shoulder forward sufficiently. Skeeter wanted to minimize the amount of powder used and work at a pressure that was safe for his falling block action.
Working incrementally, Skeeter started at 5.0 grains of Titewad, working up in 0.5 grain increments. As you can see, the 5.0 grain charge blew the shoulder forward, but left it a hemispherical shape. At about 7.0 grains of Titewad, the edge of the shoulder and case body was shaping up. Skeeter decided that 8.5 grains of Titewad was the “sweet spot”. He tried higher charges, but the shoulder didn’t really form up any better. It will take another firing or two, with a normal match load of rifle powder and a bullet seated, to really sharpen up the shoulders. Be sure to click on the “View Larger Image” link to get a good view of the cases.
The process proved to be a success. Skeeter now has hundreds of fire-formed Dasher cases and he hasn’t had to put one bullet through his nice, new match-grade barrel. The “bulletless” Cream of Wheat method allowed him to fire-form in a tight-necked barrel without neck-turning the brass first. The only step now remaining is to turn the newly Dasher-length necks down about .0025″ to fit his 0.269″ chamber. (To have no-turn necks he would need an 0.271″ or 0.272″ chamber).
Skeeter didn’t lose a single case: “As for the fire-forming loads, I had zero split cases and no signs of pressure in 325 cases fire-formed. Nor did I have any misfires or any that disbursed COW into the action of the firearm. So the COW method really worked out great for me and saved me a lot of money in powder and bullets.” To learn more about Skeeter’s fire-forming process, read this Dasher Fire-Forming Forum Thread.
*Skeeter did have a fire-forming barrel, but it was reamed with a .269 chamber like his 10-twist Krieger “good” barrel. If he fire-formed with bullets, he would have to turn all 300 necks to .267″ BEFORE fire-forming so that loaded rounds would fit in the chamber. Judging just how far to turn is problematic. There’s no need to turn the lower part of the neck that will eventually become shoulder–but how far down the neck to turn is the issue. By fire-forming without bullets now he only has to turn about half the original neck length, and he knows exactly how far to go.

Montana 1K benchrest shooter Leo Anderson has set a pair of astounding multi-match Light Gun Score Agg records. These are “records for the ages”. This season, Leo’s 6-match Score Aggregate was 99.5 (99,99,99,100,100,100), while his 10-match Score Aggregate was 96.8 (84,94,95,98,99,99,99,100,100,100). That’s amazing consistency. Given how hard it is to shoot a single 100 score at 1000 yards, Leo’s Aggs are jaw-dropping. It will be a long time before these Agg records are broken (if they ever are). Leo set his 99.5 (6-match) and 96.8 (10-match) records shooting a 17-lb rifle chambered for the 6mm Dasher. The Lawrence barrel was chambered by Montana gunsmith John King and Leo did the stock work himself (starting with a Shehane MBR Tracker).
99.5 Six-Match Agg and 96.5 Ten-Match Agg at 1000 Yards
Leo set these multi-match Agg records at the Deep Creek Range near Missoula, Montana. Tom Mousel, another record-holding Montana shooter reports: “Our Agg season is now complete here in Montana. Leo ‘Legend’ Anderson has broken both the 6-match and 10-match score aggregate records. He hasn’t just broken them, he has smashed them, with a couple Aggs that are truly remarkable. As a fellow 1000-yard competitor, I fully understand what it takes to grind out a quality Aggregate. What Leo has done this year is the most impressive thing I think we might ever see in the 1000-yard benchrest game. Leo is one of the best of the ‘good guys’, and also, in my opinion, Leo is the best 1000-yard shooter to ever grace our sport. You’d have to check with Leo, but I believe these are his 14th and 15th world records in his career. Leo also holds our Club record for Light Gun group and score, when he drilled a 3.476″/100 back in August of 2008″. (See photo below)
Record-Breaking 6mm Dasher Light Gun Specs
There’s nothing really exotic about the 17-lb Light Gun with which Leo set his score records. The stock is a laminated Shehane MBR Tracker with some modifications by Leo to make it track better. Leo altered the angle of the toe to match the forearm and modified the taper of the sides of the buttstock to ride better in the bags. Pillar-bedded into the stock is a Stiller Viper Drop Port. Leo loves this action. He says it is very fast to operate and the flat bottom makes it easy to install in the stock. In addition, the Viper action works well with his preferred CCI 400 primers: “I can run stout loads of H4895 with the Viper without cratering the primers. Some guys with other factory and custom actions have problems with the CCI 400s which are not as hard as the 450s.”
The 29.5″, 5-groove, 0.237″ land, HV-counter barrel was crafted by Lawrence Barrels. Based in Lewiston, Montana, Lawrence Barrels currently makes mostly AR barrels, but Leo says they make great cut-rifled tubes: “I currently have Lawrence barrels on both my Light Gun and my Heavy Gun. These Lawrence barrels both shoot great. I think they are the equal of the best examples from top barrel-makers such as Krieger and Bartlein.” Leo has tried straight-contour barrels, but he prefers some taper (similar to a Krieger #17 contour): “In my experience, tapered barrels seem to shoot better, at least in a 17-pounder. The gun is less nose-heavy and tracks better.” The barrel on Leo’s record-setting Light Gun currently has about 900 rounds through it.
For optics, Leo runs a 12-42x56mm Nightforce BR model with NP2DD reticle. Leo tells us: “the NP2DD reticle is my favorite and I have great confidence in the Nightforce. We tried it side-by-side with a big name European-made high magnification scope, and the Nightforce was visibly better. At 1000 yards it had better clarity, better sharpness, better resolution.”
Record Setting Dasher Recipe: Berger 105gr VLD, Hodgdon H4895, CCI 400, Lapua Brass
While many top 6mmBR and Dasher shooters use Varget or Reloder 15, Leo prefers Hodgdon H4895, which has a slightly faster burn rate. Leo tells us: “Right now, the H4895 and CCI combo is giving the best accuracy, and it’s a clean combination. I’ve shot a lot of Reloder 15, but the H4895 burns so much cleaner.” Leo’s load is running around 3050 fps, but “he’s not too concerned with what the chronograph says — when we tune our loads we go by what shows up on the target.” Leo is loading a bit more than 32 grains of H4895. (Editor’s NOTE: This load is for fully fire-formed Dasher cases ONLY. It is NOT safe to use in a 6mmbr with 105s.) Leo’s favorite projectiles are the “thin-jacket” Berger 105gr VLDs, pointed with a Whidden pointing tool. Leo turns his necks with a K&M neck turner.
To save on barrel life, Leo fire-forms his brass using a separate barrel. He prepares the brass with a false shoulder, then fires the cases loaded with pistol powder, cream of wheat and low-density plug in the end. He tried forming case with pistol powder alone, but that required much more powder and didn’t produce results as good as the cream of wheat method.
Shooting Fast — the Importance of Smooth Tracking
Leo tells us that you need a great-tracking rig to be competitive in the 1K game these days: “Some guys are getting 10 shots downrange in 20 seconds or less. It takes me about 30 seconds.” To shoot that fast, the gun needs to track perfectly so you can just slide it back and stay on target. “If you want to shoot fast, everything’s got to be working right — and your stock really needs to track well. If you’re chasing the knobs on your rest, you’re not getting [your bullets] down range.” Leo says the stock’s geometry must be “near perfect” in order for the gun to come back to the same spot shot after shot.
Leo Anderson’s Advice for New Long-Range Shooters.
We asked Leo if he had any advice for shooters new to the long-range benchrest game. Here are some of his thoughts:
1. Pick a Winning Cartridge – Leo thinks the Dasher is just about perfect for a 17-lb rifle: “Any more cartridge than that, you have too much gun movement. Something in the Dasher range is the perfect size. We shoot the Dashers around the 3050 fps node. Even with the 6-6.5×47 you’re just burning more powder, and at the higher node, the gun starts rocking and things start getting away from you.”
2. Get Good Equipment Right from the Start – “Go ahead and bite the bullet and buy good stuff right off. Too many guys try to get off cheap in the beginning. They end up buying two or three guns as they upgrade. You save money in the long run by buying good stuff in the beginning.”
3. Practice, Practice, Practice – “We get a lot of practice in the process of tuning and load development. We put in the time — on things like bullet sorting, case prep, load tuning.”
4. Keep Pushing for Perfection – “A lot of guys get a load that seems pretty good, and then they get lazy. Don’t be content when you get a 6-inch group at 1000, because the gun might shoot a LOT better. I’ve got Aggs in the five-inch range.”
Leo reports: “Here’s our ‘secret’ 1000-yard range out in the sticks where we do some spring tuning”.

Richard Schatz won the 2010 IBS 600-Yard Nationals held recently in St. Louis, Missouri. Congratulations to Richard for this big win against very capable competition! Posting in our Shooters’ Forum, Richard Schatz noted: “It was a great time seeing old friends and making new ones. The St. Louis range turned out to be very challenging with winds switching fast enough to keep everyone on their toes just trying to stay in the game.” Forum member David L. (aka David2) attended the match and tells us: “St. Louis has a very nice facility. The Match Director and target crew [ran] a good match, even with some gusty winds blowing off or loosening a couple of targets.”
Match Report by Jerry Kloeppel
St. Louis hosted 74 shooters at its first 600-Yard Nationals. Pleasant temperatures and strong, gusty, switchy winds both days kept shooters off-balance. As usual though, the weather conditions didn’t seem to bother some while driving others crazy. Friday was all Light Guns and at the top of the heap was Dan Hobbs with a First Place group Agg of 3.013. Richard Schatz came in second with 3.019 and Samuel Hall in third with a 3.028. Now that’s a tight race!
For score, Hobie Bond [took first] with a 361 followed by Jay Cutright’s 355 and Mike Jakubczak’s 352. Mike also won the overall Light Gun Championship. The Small Group of the day went to Sam Hall with an amazing 1.128″ in those conditions. Richard Schatz found a way to keep them in the middle… with two perfect 50s for the day. Also on Friday Mike Hanes won a Kelbly stock for a shot closest to the center.
Saturday’s winds were even worse than Friday’s and again some shooters made it look easy. In Heavy Gun, Sam Hall took first in group with an impressive 2.136 Agg. Al Forbes finished second with a 2.590 and Schatz was with with 2.612. The score Champ was Richard Schatz with a 355 total, followed closely by Richard Griffins (352) and Dan Hobbs (351).
Here is how the Two-Gun overall standings worked out. In Two-Gun Group, Sam Hall was first, with a 2.582 Agg. Schatz was second with 2.815 and Al Forbes was third with a 3.004. A group size tie-breaker gave the Two-Gun Score title to Richard Schatz over Richard Griffin (both men racked up identical 696 scores). Also on Saturday, David Dorris of Benchsource presented Don Elder with a shiny new Benchsource annealing machine as a prize for the shot closest to center. And that brings us to the 2010, IBS 600-yard overall Champion: Richard Schatz. Congratulations Richard.

This weekend, October 22-24, the Sacramento Valley Shooting Center hosts the NBRSA 1000-Yard National Championship (aka “Sloughhouse 1000″). Many of the nation’s best long-range shooters will be on the firing line. There will be two classes, Light Gun and Heavy Gun, with match fees of $75.00 per class. The Championship Match starts on the 22nd at 8:00 A.M. at Range 12. There will be a “sight-in & weigh-in” day on October 21st. On Friday and Sunday, food may be purchased from Jake’s Hot Dogs. On Saturday, lunch will be catered by Sierra Smokehouse Barbecue. (Sierra’s BBQ fare is truly superb!)
This is the view from 600 yards. The 1000-yard firing line is fully covered and shaded.
With blustery weather and moderate chance of rain predicted, it will be interesting to see how the 6mm Dasher aces like Richard Schatz do in tough conditions. This could be the weekend to shoot a big boomer in both classes. Past 1K NBRSA Champ Jerry Tierney will be there with his straight .284 Win. He is working on a 7mm RSAUM, but it isn’t ready for the event.
The Montana NW 1000-Yard Benchrest Club held its annual Championship at the Deep Creek Range near Missoula, Montana last weekend August 13-15. A record number of shooters attended. The winds were strong and shifty at times, and were “not typical Deep Creek conditions” according to Tom Mousel, the overall Two-Gun Winner. Despite the challenging conditions (some shooters had trouble staying on paper), competitors went home happy as match organizers gave out over $21,500.00 worth of prizes. All 56 shooters left with a prize, and many of the top competitors came home with a brand new Nightforce scope. Top shooters included: 2-Gun Champion – Tom Mousel (Kalispell, MT); Heavy Gun Winner – Ed Janikowsky (Kalispell, MT); 17 lb. Class Winner – Leo Anderson (Kalispell, MT); and 11 lb. Class Winner – Duane Capehart (Sula, MT).
Over the course of the weekend, despite the difficult winds, some great groups and scores were shot. Richard Schatz of Bismark, ND, nailed a 100 score/5.502″ group on Saturday, and Scott Nix of Whitefish, MT, shot a remarkable 100 score/4.556″ group on Sunday. Both men were shooting 6mm Dashers. Schatz got his 100 in a Heavy Gun Relay (though his rifle is not a true Heavy), while Nix shot his century score in 17-lb. Relay. Two-Gun Overall Champ Tom Mousel shot a 6mm Dasher in both 17-lb and Heavy Gun Classes. Tom’s match-winning and record-setting Dasher features a Stiller Viper Drop-port action, Krieger 8-twist barrel, Nightforce scope, and Shehane Tracker stock. Tom’s gun was smithed by Montana gunsmith John King (King Machine). Tom shoots Berger 105gr VLDs, pushed by a stout load of H4895, with CCI 400 primers. Tom has at least 12 firings on his Lapua cases, which he anneals every 3-4 firings with a Bench-Source annealing machine.
6mm Dashers Dominate 2010 Montana 1000-Yard Championship
Missoula’s Deep Creek Range is definitely “Dasher Country” and the diminutive 6mmBR Improved cartridge totally dominated the event. Consider this, four out of the top five places in the two-gun overall were shot with Dashers (Barry Bluhm was 5th overall with a 6-6.5×47). All of the top five places in Heavy Gun were Dashers, and in the 17-lb Class, again Dashers were first through fourth, with Bluhm’s 6-6.5×47 in fifth. After the match Barry told us: “You know, my 6-6.5×47 is shooting well, but I’m thinking of going to the Dasher when it’s time to re-barrel. I’m tired of getting beat by them.” The performance of the little cartridge is pretty remarkable, when you consider this entire match is shot at 1000 yards. Check out the equipment list for Saturday’s Heavy Gun Relays 1 & 2 (below). The fact that the “top guns” are running the little Dashers, even in an unlimited weight class, speaks volumes. While other larger cartridges offer superior ballistics at 1K, the Dasher is “inherently accurate”, and its low recoil allows the best shooters to fire ten rounds in well under 30 seconds. When you can nail ten shots all in the same condition, the Dasher is hard to beat.

Tom Mousel of Kalispell, Montana, has set two new multi-match Aggregate 1000-yard World Records. Shooting at the Deep Creek Range in Missoula, Montana, Mousel set a new 10-Match Light Gun World Record with a 5.8954″ Aggregate. That’s an average group under 6 inches for 10 matches! Mousel also set a new Light Gun 6-Match World Record with a 4.8813″ Aggregate. That 4.8813″ Agg bettered the existing 5.251″ Light Gun 6-Match Record Agg set by Mousel himself last season (2009). Congratulations to Tom for a lot of hard work and some real fine shooting! Tom set these Aggregate records over the course of the 2010 season of the Montana NW 1000-yard Benchrest Club, which is affiliated with the Original Pennsylvania 1000 Yard Benchrest Club (Williamsport).
Tom’s record-breaking Light Gun is chambered as a 6mm Dasher (see photo above), which is an “improved” version of the 6mmBR Norma case. Tom uses a Stiller drop-port (bottom-eject) Viper action, set up in a Shehane laminated Tracker stock. Duane Capehart, who competes with Tom at the Deep Creek range, says that bottom-eject action helps Tom “shoot like a house on fire. Tom can get all ten shots off in under 25 seconds. He’s speedy, that’s for sure.” The barrel is a Krieger 1:8″ twist, 4 groove with about 1200 rounds through it so far. Tom has at least 12 firings on his Lapua cases, which he anneals every 3-4 firings with a Bench-Source annealing machine. He currently shoots Berger 105gr VLDs, pushed by a stout load of H4895, with CCI 400 primers. Over the course of the season he has chased the lands to maintain a seating depth about .003-.009 off the lands. Tom explains: “Seating depth is very critical with the VLDs. A few thousandths can make the difference between a fat ugly group, and something to brag about.”
Noted stock-maker and past 1000-yard Shooter of the Year Bill Shehane observed: “If I am not mistaken, [Mousel’s 10-match Agg] is better than the existing Heavy Gun 10-shot Aggregate group records. I don’t think you or I will live long enough to see either of Tom’s records broken. Think about it — 10 matches over 10 different days in extremely different conditions. That’s 100 shots in under six inches. That’s remarkable for any gun — much less a Light Gun. A 6-match or 10-match Agg is never a fluke. This is an Aggregate record we may never see the likes of again. Tom’s a modest guy and someone needs to give him some credit. I’ve been at this game a long time and know the effort one has to make to accomplish something like this.”
Annual 1000-Yard Championship In August If you want to compete with Tom Mousel and the whole Deep Creek gang, head up to Missoula in August. The Montana NW 1000-yard Benchrest Club will host its 1000-yard Championship Shoot on August 13, 14 and 15. The Montana Club’s current rules allow IBS and NBRSA guns in the 17-lb and Heavy Gun Classes. In addition there is an 11-lb Sporter class. All guns shoot 10-shot groups at 1000 yards.
Entry fees are $30 per gun, per day. Camping is available at the Deep Creek range, and there will be a Catfish Fry on Friday and a Steak Dinner on Sunday after the last match. Tom says: “Come to Montana and shoot with us. We have over $16,000 worth of prizes this year.” For more info, or to request entry forms, contact Tom Mousel at 406-450-0917, or Pat Capehart at 406-821-3737.

The 6mm Dasher is based on the 6mm BR cartridge with the shoulder blown forward about 0.100″ and “improved” to 40°. Case capacity is raised to about 41.0 grains. This allows the Dasher to drive 105-108gr bullets comfortably at 2970-3000 fps without over-stressing the brass. A popular load used by many successful Dasher shooters is 33.3 grains of Reloder 15, CCI 450 primers, with 105gr Berger VLDs, .010″ in the lands. This is a “warm load” and should only be used with fire-formed brass. As with any load, start 10% low and work up. You may also have good luck jumping the bullets .020″ or more.
Robert Hoppe, one of the top 600-yard shooters in the country, was the 2009 NBRSA 600-yard champion. In 2007, shooting a 6 Dasher, Robert nailed a 0.5823″, 5-shot group. At the time it was the smallest group ever shot in 600-yard registered benchrest competition. In 2008, John Lewis shot even smaller with an IBS Heavy Gun, but Robert’s 0.5823″ still remains the NBRSA 600-yard record, and we believe it is the smallest group ever shot at 600 (in registered BR competition) by a 17-lb class rifle. Robert has been very successful in the 600-yard game, and is one of the best 600-yard shooters in the West. He knows how to wring the best accuracy out of the 6mm Dasher cartridge. Here Robert offers some tips on load development and tuning for the 6mm Dasher.

It was “Ladies First” at the California State Long-Range Championship held this weekend at the Coalinga Range in central California. Palma ace Noma Mayo topped a field of 26 shooters (24 men and 2 women) to take the CA title with an impressive 787-34X score.
The diminutive senior lady shooter had the men saying “Noma, ‘No Mas'” by the end of the 3-day event. Using the latest (#2156) Sierra 155gr Palma bullets, Noma steered her .308 Win, iron-sighted Palma rifle to victory, displaying great consistency and superior wind-reading skills. Finishing second overall was Michael Dunio (782-29X), while Noma’s husband Marty Mayo took third with a 779-16X score. Marty teamed with Noma to win the two-person Team match on Saturday, with a combined 385-7X.
Shooting his trusty 6BRX, Peter White took the F-Class title with a strong 785-36X score. Taking second was our friend and Forum member Gary Wood, who shot a 778-28X with the 6.5-284 featured recently in the Daily Bulletin. Gary Childs placed third in F-Class (769-25X), shooting a straight .284 Win with a handsome stock he crafted himself. When comparing these scores to the iron sight shooters, keep in mind the F-Classers shot a target with much smaller ‘X’ and scoring rings. We want to give special thanks to Gary Wood, whose generous donation to AccurateShooter.com made it possible for this Editor and assistant Mark LaFevers to cover the event.
There were some beautiful long-range rigs at the match, including many Gary Eliseo tubeguns. (Gary competed at the event, and shot well on Friday and Saturday, but fell victim to shifty winds on the final day.) In addition to the high-tech tubeguns, many handsome wood-stocked Palma rifles were used, including a Bastogne-walnut-stocked beauty built and shot by gunsmith Tom Luhmann of TLC Gunworks in Clovis, CA.
An interesting “California-legal” AR Platform rifle caught Mark’s eye. It sported a handsome matte camo finish, but the chambering was the most noteworthy feature. This rifle was chambered as a 6mm Dasher, an improved 6mmBR with a shorter neck and 40° shoulder. Most of the AR match rifles we’ve seen have gone to a Grendel-based case, if they step up past the .223 Remington. The 6BR parent case uses a .308-sized bolt-face, whereas the Grendel case rim is smaller. Also, with its steep shoulder angle, the Dasher can prove challenging to feed. However, the gun’s builder Marcus Naslund said they had achieved good feeding and function by opening up the gas port and adapting a custom single-stack magazine, made from aluminum billet. Despite California’s Draconian gun laws, this rifle is legal for sale in the Golden state because a “tool” (which can be a bullet tip) is required to remove the otherwise “non-detachable” magazine.

After scanning the equipment list for the recent 600-yard IBS Nationals, one of our readers noted how the 6mm Dasher dominated the Top 10 list in both Light Gun and Heavy Gun Classes. But Sam Hall won the Grand Agg with a straight 6BR, Mike Davis won the Heavy Gun Agg with a 6BRX, and Richard Schatz won the Light Gun Agg with a 6mm Dasher. So which cartridge should you pick? What’s the best for the 600-yard game — 6BR or Dasher or BRX?
Sam Hall, 2008 IBS 600-yard Shooter of the Year and back-to-back 2009/2008 IBS 600-yard National Champion, offers this advice:
“I shot a Dasher most of this year at IBS 600-yard matches and shot a no-turn BRX in a couple of shoots. I even tried a BRDX (40° improved with a longer neck than Dasher) in a practice barrel. By looking at the results on my target, I would never have been able to tell the difference between any of them if I did not already know what cartridge I was shooting. The 6BR or an improved version are just downright inherently accurate. They are all easy to load for and tune. I do believe the 6-6.5×47 Lapua is harder to get tuned than the 6BR. There are always the exceptions though. I have been beaten a few times this year by one exceptionally good shooting 6-6.5×47.
My next step is to try a no-neck-turn 6BR. I have been beaten by some a few times. I am now wondering if neck-turning is worth the time. A lot of the top BRX and Dasher shooters are not turning their necks and doing extremely well.
In my opinion pick your favoite BR or improved version, learn it well, practice, and don’t deviate. If someone you know shoots a BRX (or Dasher) and has a lot of experience with it — that is a good head start for loads. You can then compare what shoots good and what does not. I sure did not learn everthing on my own. I got some good load info here on this website (AccurateShooter.com) and I used to hound Terry Brady to death for loads to find out what he was winning with. Don’t be afraid to ask questions! I still do! Good luck and have fun.”

Given the many matches won and records set by 6BR Improved cases, both 6 BRX and 6 Dasher varieties, product planners at Nammo Lapua have shown some tentative interest in manufacturing an official 6BR Improved case. This would be something very similar to a 6BRX, with about 41-42 grains of capacity, compared to about 38 grains for the 6BR. The case would be bigger than a 6BR, but smaller than a 6-6.5×47 or 6XC. The case would retain the small primer pocket and small flash hole of the 6BR case. A “bigger BR” would easily drive the 105-108gr 6mm bullets at 2950-3000 fps, where they often seem to shoot the best.
Before you jump out of the chair shouting “Oh Boy!”, keep in mind that Lapua’s interest is very preliminary — the engineers are merely fact-finding. This is just in the “idea stage”. Lapua’s cartridge designers are, however, intrigued by the accuracy and efficiency of the 6BR Improved case. Anything that regularly sets world records is worth considering. And Lapua would like to have a cartridge that will prove superior to the 6XC in international 300m competition.
AccurateShooter.com’s Editors have advocated the production of an “official” 6BR Improved. This wildcat deserves to become standardized. We suggest that it be similar to the 30-degree-shoulder 6BRX, but with a longer neck than a BRX (which loses neck length as the shoulder is moved forward). Existing BRX shooters could simply trim the necks shorter as needed to fit existing chambers. Dasher fans could proceed to “improve” the shoulder to 40 degrees, for their preferred configuration.
Obviously, as with any potential product, the question remains “is there sufficient market demand to justify production set-up and tooling costs?” We think the answer is yes. Not only would a factory 6BR Improved case be popular with Benchrest and across-the-course shooters, but this case would be great for varminters looking for something with more velocity than a 6BR but better barrel life than a 22-250. So, would you be interested in a factory 6BR Improved? Express your views in our Product Poll.

Forum Member Jim (Falconpilot) recently completed “Yeller”, a stunning new F-Class rig, chambered as a 6mm Dasher. Built with a BAT RBLP right-eject action, the gun features a Robertson Composites F-Class stock and Krieger 28″ barrel. With Berger 108gr VLDs, Reloder 15 and Wolf primers, “Yeller” has shot in the ones and low twos at 100 yards.
Jim’s new Dasher has already proven itself in competition. This past weekend, Jim took “Yeller” to Camp Robinson. In the very demanding 1000-yard F-class division, Jim shot 197/6X, 197/0x, and a 199/10X. Yeller’s proud owner tells us: “On the final 199/10X relay the one shot that drifted to the 9 rings was about 1″ out — I called the shot, so the gun performed beautifully! Still learning the right ‘hold’ for this stick, but I can tell you that…having a gun that you have complete confidence in makes a huge difference.”
We asked Falconpilot about his bright yellow color choice. “The stock came in a basic dark gray and I wanted something that I couldn’t lose on the firing line! The color turned out better than I hoped. The paint is PPG Lemon Ice Yellow, with PPG Clear. I shot a base coat of white, then the Lemon Ice, then clear. Special thanks to Howard Pitts at Pitts Precision for chambering another perfect chamber. A huge thanks to my shooting buddy and friend, Matt Owens of ARKCO Customs for helping me pillar bed the stock, and the use of his equipment. His gun is next, mine was the test subject for us, as neither one of us had ever pillar-bedded a rifle before. The result shown on the target (below) show that we got it right!”

Loading Tips for the 6mm Dasher
Jim reports: “I’ve found that using Varget while fire-forming forms the cases a little more evenly, but Reloder 15 is my ‘go to’ powder once fire-formed. I resize the brass and bump the shoulders back .0015-.002″ after every firing. Then I’ll tumble-clean the brass. I then use a .265″ bushing in my Redding neck die to resize the necks about 3/4 way down, clean the primer pockets, and reload from there.” As for bullets, Jim adds: “Every Krieger 6mm .237 barrel that I’ve had has shot the 108 especially well.”

About 24 miles east of Oceanside, California (near the Camp Pendleton Marine base) is the Pala Reservation. On that Native American land you’ll find an impressive new Casino Resort & Spa, plus an excellent shooting range. The first Sunday of every month, many of Southern California’s top shooters come to Pala to enjoy a challenging Varmint Silhouette Match. Ten targets are set at each of the following distances:
200 meters – Field Mice (also called “pikas”)
300 meters – Crows (with a triangular center cut out, just for a little more challenge)
385 meters – California squirrels
500 meters – Jack Rabbits
600 yards – Prairie Dogs
There’s a North County Shootist Association Varmint Silhouette match this Sunday, May 3rd, and your Editor will be there covering the event. We invite AccurateShooter.com readers to come join the fun. You’ll need a very accurate rifle, and 80-100 rounds of ammo. You can shoot either rested prone (F-Class style), from bipod, or from a wooden bench with front pedestal and rear bag. Any rifle 6.5 caliber or under is allowed, with no weight restrictions. Muzzle brakes are permitted. There’s a one-hour sight-in period starting at 8 am, and the match starts at 9 am sharp. The folks at Pala run a tight ship, cycling multiple relays efficiently, so everybody gets to shoot 50 targets (10 each at five different yardages), and the show is usually completed by 1:00 pm. (Then if you want… head over to the Pala Casino for some gambling fun, or maybe a spa treatment.)
At Pala varmint shoots, max caliber is 6.5mm, to limit target damage. Typically you see a BR-style rifle, with a heavy, 26-30″ barrel, often using a muzzle brake. You need a very accurate chambering, so you’ll see 6BRs, Dashers, 6-284s, 6.5-47s, and a few 6mm Remingtons. (Note, the 6.5s are limited to 109gr max bullet weight to prevent target damage.) When this Editor last shot at Pala, Forum Member John Adams was kind enough to let me shoot his wicked little 22 Dasher. It proved very accurate, and very flat-shooting. I was impressed.
Montana 1K benchrest shooter Leo Anderson has set a pair of astounding multi-match Light Gun Score Agg records. These are “records for the ages”. This season, Leo’s 6-match Score Aggregate was 99.5 (99,99,99,100,100,100), while his 10-match Score Aggregate was 96.8 (84,94,95,98,99,99,99,100,100,100). That’s amazing consistency. Given how hard it is to shoot a single 100 score at 1000 yards, Leo’s Aggs are jaw-dropping. It will be a long time before these Agg records are broken (if they ever are). Leo set his 99.5 (6-match) and 96.8 (10-match) records shooting a 17-lb rifle chambered for the 6mm Dasher. The Lawrence barrel was chambered by Montana gunsmith John King and Leo did the stock work himself (starting with a Shehane MBR Tracker).
