Can you form a wildcat cartridge such as the 6 Dasher without expending primer, powders, and bullets? Absolutely. Using the hydro-forming method you can form improved cases in your workshop with no firing whatsoever, so there is no wear on your precious barrel. Watch this video to see how it’s done:
6 Dasher Case Hydro-Forming Demonstration:
Forum member Wes J. (aka P1ZombieKiller) has produced a helpful video showing how to form Dasher cases use the Hornady Hydraulic forming die kit. This includes a two-part die (body and piston), and a special shell holder. To form the case, you insert a primer in your virgin brass, top the case off with with a fluid (water or alcohol), then run the case up into the Hydro-forming die. A few stout whacks with a hammer and your case is 95% formed.
Hydro-Forming Procedure Step-by-Step:
1. Insert spent primer in new 6mmBR brass case.
2. Fill with water or alcohol (Wes prefers alcohol).
3. Wipe excess fluid off case.
4. Place case in special Hornady shell-holder (no primer hole).
5. Run case up into Hydraulic forming die.
6. Smack top piston of forming die 3-4 times with rubber mallet or dead-blow hammer.
7. Inspect case, re-fill and repeat if necessary.
8. Drain alcohol (or water) into container.
9. Remove primer (and save for re-use).
10. Blow-dry formed case. Inspect and measure formed case.
Wes achieves very uniform cartridge OALs with this method. He measured ten (10) hydro-formed 6 Dasher cases and got these results: two @ 1.536″; 2 @ 1.537″; and 6 @ 1.538″.
Three or Four Whacks Produces a 95%-Formed Case
With a Hornady hydro-forming die, hydraulic pressure does the job of blowing out the shoulders of your improved case. The process is relatively simple. Place a spent primer in the bottom of a new piece of brass. Fill the case with water, and then slip it into a special Hornady shell-holder with no hole in the middle. Then you run the case up into the forming die. Now comes the fun part. You gently insert a plunger (hydraulic ram) from the top, and give it three or four stiff whacks with a mallet (or better yet, a dead-blow hammer). Remove the plunger and you have a 95% formed case, ready to load.
Special Shell-Holder
Hornady supplies a shell holder made specifically for the hydro die; there’s no hole in the bottom of it. Just insert a spent primer into the primer pocket and you’re ready to go. The spent primer, combined with the solid shell holder, keeps the water from seeping out of the primer pocket. The primer pushes out a little bit during this process, but it’s impossible for it to come out because of the way the shell holder is designed. The shell holder has a grove which allows the case to slide out of the shell holder even when the primer protrudes a bit.

The bar is raised yet again — the standards for long-range accuracy keep improving. Two talented Montana shooters have both gone sub-four inches for a 1K 10-Match Aggregate. What that means is that over TEN matches, these guys have averaged under 0.4 MOA at 1000 yards. Think about that. Most shooters will be happy with half-MOA at ONE HUNDRED yards. These guys are beating that by a significant margin at ONE THOUSAND yards, and they have done it for a whole season.
1000 Yard Multi-Match IBS Records Fall at Deep Creek
David Torgerson and Tom Mousel both broke the 10-match Light Gun Group Aggregate (Agg) record. Tom also broke the 6-Match Light Gun Group Agg record. Prior to these brilliant performances, the existing IBS 10-Match Agg record was 4.3155″. David crushed that with a 3.7946″, as did Tom with a 3.8734″. The existing IBS 6-Match Agg Record was 3.072″ and Tom shot a 2.954″, which will be a new record.
This is the first time in history that anyone has Agg’d in the threes for the 10-Match and in the twos for the 6-Match! For those not familiar with 1000-yard IBS matches, the Season Aggregate is based on ten matches. All ten are averaged for the 10-match Agg and the best six are averaged for the 6-Match Agg.
Shooters Established New Records with Multiple Guns and Multiple Barrels
David shot the majority of his targets with a Bat B action and Broughton 5C barrel. But he also shot his BAT SV and Borden BRM with Krieger and Lilja barrels. David’s 1K rifles feature Deep Creek Tracker stocks and March scopes. He shot Vapor Trail 103gr bullets in the all the rigs, and all his barrels are chambered in 6BRA — a 40° wildcat based on the 6mmBR Norma. The 6BRA retains the long neck of the parent case, but has more case capacity. Some people say the 6BRA is a bit easier to tune than the 6mm Dasher, but it still achieves that ultra-accurate 2920-2960 FPS velocity node.
Tom Mousel shot his 6- and 10-match Aggs with two rifles, splitting time between his BAT Neuvo LR and Borden BRM. Both are chambered in 6BRA and he shot multiple Krieger barrels. Tom told us: “Thanks everyone. David was pretty steady all year, while I took more of an up-and-down route. At one point early on I thought there’s no way this would be salvaged.”
The Neuvo-actioned gun (shown below) features a McMillan/Wheeler LRB stock, with a March scope on top. In that rifle, Tom shot 103gr Vapor Trails. Mousel’s Borden BRM gun features a Deep Creek Tracker stock and Sightron scope. In that 6BRA rifle he shot 103gr Roy Hunter bullets.

COMMENT by Alex Wheeler
If this doesn’t make you give up the idea you need that one hummer barrel to win I don’t know what will. Yes, you need the best equipment, but you also need the best tune and knowledge to stay on top of it. These two guys are some of the most dedicated tuners and testers I know. Well done! And well deserved!
It IS noteworthy that multiple rigs were used. Posting on Facebook, Alex H. said: “Holy ****! Tom did it not only with multiple barrels, but with two rifles AND multiple barrels? That is some outstanding performance! And Glenn K observed: “It was an awesome season to watch unfold. Congrats guys!”

That’s custom paint on the stock, NOT a Hydro-dip coating. Impressive paintwork!
Our Sunday GunDay showcase rifle belongs to Shane Sivertsen (aka SoDakDasher in our Forum). This eye-catching tactical rig was smithed by Travis Stevens at TS Customs in Miller, South Dakota. Shane tells us that Travis is a “top-notch builder who builds tack-driving rifles that are still extremely shooter-friendly. Plus he is one of the friendliest guys you’ll meet.”
This rifle features a Lone Peak Fuzion Action with Trigger Tech Diamond trigger (flat shoe). Up front is a Benchmark 26” MTU barrel chambered in 6mm BRA (a 40-degree 6mmBR Improved “BR Ackley”). It’s all nestled into a McMillan A5 stock with adjustable cheekpiece. Getting him on target is a Vortex Razor 4.5-27x56mm optic in Hawkins rings with a Vortex throw lever on the power ring for quick magnification changes. The Atlas PRS Bipod rides on an Area 419 ARCA rail up front. The barrel is finished off with a Piercision 5-Port Self-Timing Muscle Brake.
Custom Camo-Pattern Paint Job
All work on this rig was performed at TS Customs, including Cerakoting the action. The pattern on the McMillan A5 stock is NOT a hydro-dip! That is a custom Kryptek camo paint-job done in-house by a TS Customs employee. Shane liked the Kryptek pattern from day one: “It’s always a good thing to do something a little different to your equipment to stand apart from the rest of the pack.” Shane says the paint pattern is the first thing everyone notices about the rifle.
6mm BRA Chambering
Shane spent quite some time trying to decide which 6mm cartridge to choose. After much deliberation with Travis, he chose the 6mm BRA, mainly due to the reputation this little cartridge has earned for accuracy and ease of tuning. This rifle is Shane’s second TS Customs-crafted rifle: “the [other] is basically the same action/barrel combo but set in an MPA chassis and chambered in 6mm Dasher.”
Excellent Accuracy with Varget and Berger 105gr Hybrids
Shane’s 6mm BRA is showing impressive accuracy: “Thanks to Mother Nature this spring (with cold, snowy weather), I have only been able to get 100 rounds fire-formed and the barrel broken-in. I started with 30.5 grains Varget in Lapua BR brass with CCI 450s and topped off with Berger 105gr Hybrids. Velocity averaged 2830 FPS with an SD of 4.7 from 10 rounds randomly picked from the lot.”
Shane knows there’s still more load development to do. But this rifle is grouping under one-half MOA and Shane says the gun can definitely out-shoot his abilities. He admits it’s still a work in progress but he is happy with the gun’s performance so far.
Shane praised his Piercision 5 port Muscle brake. Shane tells us: “While I am a suppressed shooter by preference, I wanted to give this brake a try. It works very well — the control and ability to stay on target for followups is remarkable. This brake works perfect on my 18-lb 6mm BRA and will be used indefinitely. Plus it will be a little payback to the other big-braked shooters on the line.”
While it’s still such a new toy, Shane doesn’t expect to make any modifications in the near future. However he says he might “upgrade to a Tangent Theta optic by the end of this season.”

Looking 1000 yards downrange at the Deep Creek Range outside Missoula, Montana.
On Facebook recently, we saw an eye-catching rifle. Owned by top 1000-yard competitor (and past IBS Champ) Tom Mousel, this rifle was smithed by Alex Wheeler of Wheeler Accuracy. This rig features the McMillan-crafted Wheeler LRB stock with adjustable keel. It also has BAT Machine’s very impressive new Neuvo LR (aka “Neuvo M”) action, serial number LR0001. The Neuvo LR has some important design features — horizontal lug orientation, full-diameter bolt body, and advanced fire control system. More about those features below.
This gun is a shooter. Tom has already shot a 1.5″ four-shot group at 1000 yards. How does he do that? First you need a great barrel, great bullets, and superior hand-loading skills. But then it comes down to great gun-handling. You can see that in the video below. NOTE to ALL Long-Range Benchrest shooters — Watch this video! You’ll definitely learn from watching Tom shoot — he’s one of the best in the business.
Tom Mousel shoots 1000-yard ladder test with first-released Neuvo LR action, SN LR0001.
Rifle chambering is 6BR Ackley (6BRA) in 28″ Krieger barrel.
Rifle Components and Build INFO:
This rifle has a BAT Neuvo LR (aka Neuvo “M”) action glued and screwed into the LRB stock using a special bedding block, a Boyd Allen concept that Tom has requested to use on every future build. The 28″ Krieger 1:8″-twist HV barrel was indexed using a little different method than most use. It is “panning out well” says Alex, who adds: “So far it has shot [multiple low ones] with two barrels and three different bullet types. This rifle is definitely one of the better shooters I have seen.” We’d agree — owner Tom Mousel has had a 1.5″ 4-shot group at 1000 yards in testing, plus some “zero” 3-shot groups at 100 yards.
Chambering is the 6mmBR Ackley (6BRA). The stock is a Wheeler/McMillan LRB stock with vivid orange and black paint job. It features an adjustable keel in the rear. Trigger is a Bix N Andy unit from Bullets.com.
This BAT Neuvo LR action is a Left-loading Drop Port. Cartridges eject out the bottom of the action.
BAT Machine Neuvo Long Range “M” Action
This is the “Long Range” version of the BAT Neuvo. Dwight Scott and Chris Harris were the original inspiration. I worked with Chris to come up with a version for long range. The main differences for the LR Neuvo (compared to the shorter Neuvo) are this has integral lug and rail, with flat bottom and sides for better bedding. The BAT Neuvo LR is available in drop port, dual port, and single port as well as magnum.
Take a look at the bolt. Notice the lug orientation and full diameter bolt body. There are no bolt raceways in the action and the two lugs sit HORIZONTALLY when the bolt is closed — that’s different than the vast majority of other two-lug actions.
Alex Wheeler says the Neuvo is a winner. He thinks some of the action’s design features really do contribute to enhanced accuracy: “The … fire control (firing pin assembly) carries a lot of energy and has a very “clean” release. This is an excellent design with many small details that combine to deliver superior function. In addition, the full-diameter bolt can be fitted tighter than one with lugways. Also the horizontal lugs may be why we see less vertical stringing in the groups. They are timed perfectly as well.”

One of our Forum members, Jason Peterson, pulled off a remarkable accomplishment at an NBRSA 600-yard match last fall. Last October, at the Rogue Valley SSA range in Oregon, Jason set no less than FOUR new NBSRA Score Records: Light Gun 6-Target Score (30 shots), Heavy Gun 6-Target Score (60 shots), Two-Gun 6-Target Score (45 shots), and Two-Gun 12-Target Score (90 shots).
Jason was shooting a 6 BRA (6mmBR Ackley) Light Gun with Borden BRM action, LBR stock, and 1:8″-twist Krieger barrel. Bedding was done by Alex Wheeler. Notably, Jason’s father chambered the Krieger barrel — Thanks Dad! The load consisted of 108gr Bergers pushed by Hodgdon H4895. Writing in the NBRSA Magazine, Bill Johnston observed: “If my memory serve me right, this is the first time in Long Range History that 4 records were set at one match by the same shooter.”

The 6BR Improved cases have become very popular in tactical competitions. In fact the Precision Rifle Blog reports that the majority of Top 10 PRS and NRL shooters are now running some version of the 6mmBR Norma case — such as the 6mm Dasher, 6BRX, or 6BR Ackley. In fact “40% of those ranked in the top 10 in either league were running a 6mm Dasher”. This short, fat 6BR improved case can push the 100-107gr bullets to 2950+ fps, a well-known accuracy node. Yes the 6mm Creedmoor and 6XC can push heavy 6mm projectiles faster to be sure, but there is a trade-off in barrel life. The 6BR Improved cases represent a “sweet spot” for the tactical game, offering outstanding accuracy, with less recoil than bigger cartridges, including the 6.5 Creedmoor.
The only real downside to the short/fat 6BR-based cartridges is that they can be finicky when feeding from a magazine, at least without some modifications to the follower and feed lips. There are kits that can help with this, but now there is an even better solution — a premium custom action designed specifically to feed the 6mm Dasher (and similar cartridges) from a magazine. This action, the Borden Super Short 6, was recently, unveiled on Facebook by PRS competitor John Hargett. This action, available in both right- and left-hand versions, features a dedicated new Super Short 6 (SS6) magazine optimized for Dasher-sized cartridges. The bolt has a shorter throw than a standard Rem short action. We think this new action could become VERY popular with tactical shooters, and varmint hunters.
John Hargett says: “Installing spacer kits or possibly having a nose dive in full-size .308 mag is in the past! This will fit all 700 stocks and chassis and AICS bottom metal. So no need to change what you are already using. Borden creates a masterful action at an extremely affordable price.”
Key Facts about the Borden Super Short 6 Action and SS6 Magazine:
1. Rem 700 Footprint — The Borden Super Short 6 action is internally tailored to the 6mmBR cartridge and its wildcats, but externally maintains Rem 700 action dimensions. This means the action IS compatible with the stock and chassis you currently own. And, the Borden Super Short 6 comes in both right-hand and left-hand versions, with PVD coating available (on action and/or bolt).
2. Rem Trigger Compatibility — The Borden Super Short 6 action works with Rem-compatible triggers, and the actions are specifically timed to work with trigger of your choice.
3. Dasher-friendly New Mag Design — The patent-pending Super Short 6 magazine is sized right for the 6mm Dasher and all the 6BR family. The follower and feed lips are configured to allow smooth, reliable feeding with no “magazine nose dives”. Even with the optimal design, the SS 6 magazine will work with all chassis profiles and bottom metal made for AICS-type magazines.
Here is the description from Borden Rifles website:
“The new action from Borden Accuracy (Borden Super Short 6) features a Rem 700 short action-compatible footprint with a shortened magazine well and shortened port set up specifically to reliably feed 6 BR, 6 Dasher, 6 BRA, 22 BR cartridges. The bolt has modified Borden bumps to aid in cycling in the dirty environment. The pictured action shows our standard bolt handle and tear drop knob. Production models will feature a handle that is threaded on the end so individuals can use their preferred knobs. I have been one of the individuals that developed the bolt timing and neutral handoff with the trigger for competition shooting to minimize rifle upset in the bags when closing the bolt. These actions will be available with either the neutral timed handoff or with about .03 to .035 inch cock on close. The cock on close option has much easier bolt lift that seems to be favored by PRS competitors. For now the bolts will have spiral flutes but future versions will have diamond flutes as an option. Development work will be done to also handle the .223 Rem and the PPC family.”
6mm Dasher and 6BR Wildcats Favored by Top PRS/NRL Shooters
1. The vast majority of PRS Shooters surveyed are now shooting a 6mm cartridge of some kind.
2. While the 6mm Creedmoor is still very popular, the 6mm Dasher is now the #1 cartridge among leading PRS and NRL competitors surveyed. (SEE Chart HERE)
3. If you include the 6BRX, 6BRA, and original 6mmBR cartridge along with the 6mm Dasher, this full family of short, fat cartridges is now used by twice as many top PRS/NRL competitors as the 6mm Creedmoor. And the 6.5 Creedmoor has really fallen from favor.
