Sunday GunDay: 6mm Dasher Winner From Forum Classifieds

Bob A. 6mm Dasher Sacramento F-Class March Madness

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.

Bob A. 6mm Dasher Sacramento F-Class March MadnessDasher 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.

Bob A. 6mm Dasher Sacramento F-Class March MadnessI 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.

2016 IBS 1000-Yard Nationals at Georgia’s Cool Acres Range

IBS 2016 1000-Yard Nationals Benchrest long range Mousel Cool Acres Georgia

Match Report by David and Donna Matthews
The 2016 IBS 1000-Yard National Championships were held September 4-5 at the Cool Acres Sporting Camp in Swainsboro, Georgia. The event was well attended with 87 Registered Light Gun shooters and 76 Heavy Gun competitors. After a hurricane-filled practice day, the competitors put forth their best effort to master the sometimes tricky Georgia range. The 1000-Yard National Match for 2016 featured a three-target Aggregate for each Division (i.e. six targets total for both classes).

The Cool Acres Range and Facility is one of the best in the country. The facility features a wide 1000-yard range lined with Georgia pines on each side. Conditions held constant for most relays. Mother Nature blessed the shooters with temperatures that were cooler than during preceding weeks. The management of Cool Acres put on a great event this year. In addition, upgraded restrooms and a new cleaning shed were added — these were very much appreciated by all. Several shooters had very positive comments about the upgrades and changes made to the Cool Acres facility in Swainsboro.

IBS 2016 1000-Yard Nationals Benchrest long range Mousel Cool Acres Georgia

The Two-Gun Champion and Overall winner was Tom Mousel from Montana with 24 rank points. Tom also won the Light Gun Overall title. Notably, Tom placed first in Light Gun Group with a stunning 3.356″ Group Agg — remember this was at 1000 yards folks. That’s a 1/3 MOA Agg at 1000 yards — truly remarkable precision.

Tom came to Georgia with one thing on his mind and that was winning. He accomplished that with his Wheeler Accuracy-built 6mm Dashers with Krieger barrels. Tom ran Vapor Trail bullets pushed by Hodgdon H4895. Finishing second in the Two-Gun Overall was 2015 winner Jim Bauer with 36 rank points. Jim took First Place honors in Light Gun Score with his Gordy Gritters-built 6mm Dasher shooting Vapor Trails pushed by Hodgdon Varget powder. The bright star of the show was Junior Division Winner Amber Brewer. Remarkably, this talented young lady topped the entire Heavy Gun field, winning Heavy Gun Score (97.667 average) and winning Heavy Gun Overall against all comers (of all ages). Her father, Henry Brewer Jr., played a role in her HG win — Henry smithed Amber’s class-winning 6.5×47 Lapua Heavy Gun, and even crafted the stock. Amber shot Berger bullets with H4895. Sally Bauer was top female shooter with her Douglas-barreled 6mm Dashers LG and HG, both built by Gordy Gritters. Sally also shot Vapor Trail Bullets with Varget.

Tom Mousel 6mm Dasher Deep Creek

Mousel won Light Gun Group with a stunning 3.356″ 5-shot Group Aggregate. That’s a 1/3 MOA Agg at 1000 yards — amazing, awe-inspiring accuracy.

Overall Winner Tom Mousel shot the 6mm Dasher cartridge in both Light Gun and Heavy Gun Classes. This little wildcat, shown below, has accuracy to spare. Alex Wheeler smithed Tom’s Rifles. Tom is shown below at his home range in Montana with an older rifle (not one used in Georgia this year).

How Hodgdon Powder Co. Started — With a Life Insurance Loan

Here’s an interesting factoid from Hodgdon Powder’s new Facebook Page:

Bruce Hodgdon

The story of Hodgdon Powders begins with one number: 4895. Founder Bruce Hodgdon, a handloader and U.S. Navy veteran, knew that after WWI tons of surplus powder were dumped at sea. After WWII, rather than let it all go to waste, Bruce borrowed against his life insurance and bought 25 tons of 4895 from the U.S. Government. It was the perfect powder for the flood of surplus M1903 Springfield rifles chambered in .30-06. The rest is reloading history.

Shown below is the life insurance loan contract that funded Bruce Hodgdon’s Purchase of 25 Tons of 4895 Surplus Powder:

Norma 203BNorma 203B Available from Grafs.com — Replaces Varget or RL15
For those folks desperate to find Hodgdon Varget or Alliant Reloder 15, we suggest you try Norma 203B. This is a very accurate powder very close in performance to Reloder 15 (it is produced by the same manufacturer, Bofors). It should give slightly more velocity than Varget, but it is somewhat more temperature sensitive.

In a 6mmBR or .308 Win, start with your Varget load with 203B. You may, then, be able to increase the load slightly, unless you’ll be shooting in very hot weather. Grafs.com has plenty of 1-lb cans of Norma 203B in stock, Item Number: NP203B1, $24.99 per pound.
