Forum member Sunbuilder unveiled his new 6-6.5×47 Lapua Improved Varmint rifle today in our Forum. The stock is a beautiful hardwood laminate from Richard Franklin. It’s a rig to envy, with a Stiller Diamondback action, Lilja 30″ 8-twist barrel, and a NightForce 8x32x56 NXS on top. First class components all the way round. Sunbuilder (Scott) has had excellent success already–his two longest groundhog hits were at 778 and 810 yards. Scott writes: “I started hunting with my new rig last week, my first full custom rifle. It was inspired by 6mmBR.com–I’m not sure if I should thank you guys or curse you.” Scott has already seen the potential of his new cartridge: “My improved version of the 6×47 Lapua has a 40° shoulder and reduced body taper. Dave Kiff of PT&G did my reamer design, and he dubbed it the ‘Long Dasher’. The increased velocity potential of this cartridge is partially due to the slightly increased case capacity. The load I am shooting now is 40.5gr N160, Berger 105gr Match BT, .010″ jam, CCI BR4, .002″ neck tension at 3115 fps. This has an ES under 15 fps, and it will group under 2″ at 500 yards if conditions hold. This ‘Long Dasher’ (6-6.5×47) seems to have a lot of potential (and that’s an understatement).”
“I am learning to appreciate how small wind changes at longer ranges can turn a 1″ group into a 4″ one with just a slight shift! I tried several powders (H4350, N160, N560, H4831sc), and primers (CCI 450, BR4, Rem 7 1/2, Fed 205Ms). I got better velocity with H4350, but my barrel likes the N160. I did find a [high-speed] node with H4350.”
A Better Mount for the Spotter and Rangefinder
Scott designed and fabricated a very slick set-up to hold his Zeiss spotting scope and Leica CRF RangeFinder. He’s built a combo bracket that holds both units rock steady, with a parallel line of sight (same axis and elevation). Smart. Very smart. Scott explains: “I built a mount to connect my rangefinder to my spotting scope. The mount can be adjusted, so the spotting scope and rangefinder are both centered on the same object. The only way I have found to get repeatable long-range readings is to make them from a stable base.” Scott, we think you’ve got a winner here with your innovative and clever design. (And we like the idea of a 6-6.5×47 with a 40° shoulder.)

Well folks, we don’t have to be shy about being shooting enthusiasts–you can join the crowd. A recent 3-year study shows shooting sports, including handgun, rifle, and shotgun disciplines, are more popular than many other highly advertised and promoted outdoor sports.

The National Shooting Sports Foundation (NSSF) commissioned a long-term study by American Sports Data (ASD), a consumer research firm for the sporting goods, fitness and health club industries. Statistics gathered over the past three years show that target shooting–with rifle, handgun and shotgun–is actually more popular than many pastimes historically considered mainstays of warm-season recreation.
In fact, participation in shooting sports tops tennis, softball, jet skiing, water skiing, mountain biking, most team sports and virtually all of the technical sports like rock climbing and kayaking, according to the most recent numbers from ASD. ASD has tracked rifle and shotgun shooting participation for many years, and began tracking handgun target shooting in 2003.
ASD research shows more than 18 million Americans enjoy the shooting sports. In a 2006 survey commissioned by NSSF, 17 percent of Americans, or about 50 million people, said they had been shooting with a rifle in the past two years. Fifteen percent went target shooting with a handgun and eight percent with a shotgun.
In overall numbers, California is No. 1 with over 2.1 million shooters, including the most rifle, handgun and shotgun shooters of any state. Texas, Pennsylvania, New York and Ohio follow. Per capita, ASD shows Idaho as the most avid shooting state (18 of every 100 people participate), followed by Utah, Wyoming, Montana and Arkansas.
For more info on the ASD survey, visit the NSSF web site, huntandshoot.org. The NSSF also offers an interactive database showing shooting ranges and clubs nationwide (See AccurateShooter Bulletin, March 18, 2007).

Forum member Danny Reever gave the new Berger 108s (See Bulletin, 6/23/07) their first taste of competition this past weekend at Shippensburg, PA. Shooting his 6BR in the Heavy Custom class, Danny won the match. Along the way he posted an impressive 1.509″ group at 500 meters (547 yards). Here’s what Danny had to say: “Yesterday I shot the new 108s in Shippensburg’s monthly Ground Hog Match. Conditions were a bit rough with switchy, gusting winds in the 5-10 MPH range and some very heavy mirage at all yardages being particularly bad at 300 and 500 meters. In fact at 500 meters you couldn’t see the scoring rings on the target let alone bullet holes. At 500 meters (547 yards) I managed a 41 score and a real nice 1.509 group considering the conditions. My total score was a 140 out of a possible 150 which was good enough for first place in Heavy Custom class for the day. This was the 108’s initial baptism by fire so to speak and they came through with flying colors.”

 We love the recoil reduction we get from muzzle brakes, but we don’t like the added noise and blast. And we’d rather not blow dust and dirt at our neighbors on the firing line. Chris Spera (Cowpuncher) of CP Muzzlebrakes has the answer to that–a brake that can be “turned off” with a simple twist of the brake housing. When the ports on the sleeve are aligned with the ports on inner section tube it works like any other muzzle brake. When the outer sleeve is turned 36°, this blocks the ports on the tube. That shuts off the brake, dramatically reducing the noise/blast it produces. CP Muzzlebrakes offers an unique and very precisely-machined product. Each brake is custom-fitted to the rifle, and Chris builds both straight and tapered versions, for $180.00 (blued or black finish). Stainless brakes, either straight or tapered, are $220.00.
Jody Calhoun of SavageShooters.com tested one of the brakes, and gave it high marks: “The effect it had on recoil was very noticeable. [My 30-06] performed very much like a medium load .308. Needless to say, I was impressed. I also liked the way it has the detent ball that allows you to go from “ON” to “OFF” in a split second without even looking. The brake stayed in position until I moved it. Operation is smooth with no slack between parts. It does have that typical muzzle brake flash and noise. Fortunately, its ports are angled in a much better fashion than most other brakes, making it less offensive[.]”

Do you have a Wilson case trimmer but can’t afford the $84.00 to add the handy Micrometer upgrade (Sinclair Int’l item 05-4500)? Well Boyd Allen has come up with a clever use of a standard set of calipers that lets you set the cut length precisely within .001″. Just open the jaws of your caliper and put one jaw on the outboard end of the ring (with set screw) that holds the threaded length-adjusting rod. Set the other caliper jaw on the flat face at the end of the threaded rod that contacts the case rim. If you have a sample case set to the correct cut length, use that to set the position of the threaded rod. Then use your calipers to measure that length. This way you can repeat the cut length each time, or adjust the trimmed case precisely in .001″ increments.
If you change from one cartridge to another, just use your calipers to re-set the desired cut length. Alternatively, ReedG notes you can use the inside caliper jaws and measure directly from the end of the threaded rod to the cutter face. That’s a bit trickier, but it measures actual trim length.

 Our AccurateShooter Forum is a cornerstone of this website, attracting over 5,500 visitors per day, and generating nearly 700,000 page-views per month. For the past two years we offered the Forum in two formats–a standard format that fit within the same, general layout of the editorial pages, and a “full-screen” format that dispensed with the navigation buttons on left and top in the interest of providing more “real estate” for the readers.
We found that, once users became familiar with the Forum they almost universally preferred to use the wide layout version of the forum. This reduced the need to scroll around, and it also allowed you to view large photos better. In light of this user preference, we have now officially switched over to an “all-wide, all the time” Forum format.
In addition we’ve added some significant upgrades. A Forum FAQ + HELP section was added today. In addition, we have added a very powerful poll module. This allows us to run multiple, photo-illustrated surveys at the same time. The polls are set to randomly rotate each time the main forum page is refreshed. The ability to provide photos of products and allow users to voice their preferences should yield some fascinating results. At right (above) you see one of six polls actively running on the forum. Below is a screen shot of the new Forum displayed at nearly full extension on a 19″ monitor. As you can see, there’s lots of room. Hopefully readers will value this upgrade and the change will demonstrate that “bigger is better” when it comes to web pages.

Over the past few weeks, Berger Bullets has been evaluating three new tangent ogive (non-VLD) bullets, in 105, 107, and 108 grain weights. Berger sent samples to many top shooters, including Forum members Danny Reever, James Phillips, and Wm. Roscoe. The 107s shot the best for James (see Test Results), but Danny and many other shooters reported great results with the 108s, which seems to have a slightly shorter boat-tail than the other two prototypes. Here’s one of Danny’s targets, shot with an 8-twist 6BR with a .104″ freebore:
Yesterday, Michelle Gallagher of Berger announced that the 108-grainer had been selected as the design that will go into production. The 108s will start rolling off the bullet presses for general consumption very soon. The specs on the 108gr Berger are: 1.225″ OAL, .712″ base to ogive, .533″ bearing surface length, and 108.08 grains average weight (Measured with Acculab MXX-123).
Why is Berger bringing out this new bullet when the existing 105 VLD shoots so well? A tangent ogive bullet is generally considered to work well jumped (i.e. seated away from the lands), whereas secant-ogive VLDs typically (but not always) prefer to be seated in the lands. This new bullet should offer optimal performance for shooters who prefer to jump their bullets. Berger’s Eric Stecker has explained: “All VLD bullets (any brand) are made using a secant ogive. This results in a more abrupt transition into the ogive radius as compared to a tangent ogive (non-VLD of any brand). This abrupt transition on the secant ogive (VLD) bullets means that the ogive contacts the lead angle differently than a tangent ogive (non-VLD) will.”
