Forum member Scott S. (Sunbuilder) has built a sweet long-range varminter based on the 6.5×47 Lapua cartridge necked down to 6mm and then improved to 40 degrees, with slightly less body taper. Scott tells us that “improving the case adds about 2.0 grains to the case capacity”. This allows Scott to run the 103-108gr bullets at well over 3100 fps, with no pressure issues. Scott calls his Improved case a “Long Dasher”, a name suggested by Dave Kiff of Pacific Tool & Gauge.

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.

6-6.5×47 Improved Works Well with Many Powders
Scott’s 6-6.5×47 Lapua Improved varmint rifle features a Stiller Diamondback action, Lilja 30″ 8-twist barrel, Richard Franklin stock, and a NightForce 8-32×56 NXS. Scott has had excellent success–his two longest groundhog hits were at 778 and 810 yards. Scott has tested many powders with his 6-6.5×47 wildcat: “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. 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).”

Pennsylvania’s Mifflin Country Sportsmen’s Assoc. held one of its triple-yardage Groundhog Shoots on May 10, and the results just came in. This is a very popular match with targets at 200, 300, and 500 yards. It’s a score match, so small groups are nice, but they better be centered. We were interested in the match results because it shows the rifles that folks are using, and what’s winning, in both factory class and “Custom Limited” classes. (At Mifflin, Custom Limiteds are typical 600-yard benchrest Light Guns–full customs weighing 16.5 lbs or less.)

In Custom Limited Class, 8 of the top 10 places were taken by 6BRs, with one 22 BR, and one 6 PPC. That’s a pretty emphatic demonstration of both the popularity and the accuracy of the 6BR cartridge. Rod Morton and Steven Kotecki tied for first with 143 points apiece. Rod was named the winner, based on “X-Count”, as Rod had 7 “Xs” compared to 6 “Xs” for Steven. Now that’s a close match. Joe Pellegrene was just one point shy, to finish third with 142 points.

In the factory class, Jesse Hall, a Junior, had highest score, 125-1x, shooting a .223 Rem. Next highest factory shooter was Bill Slattery with 119-3X, also shooting a .223. The .223 Rem was the most popular chambering in factory class.

Can the .223s shoot with the 6BR? Looking at the scores, the .223s were pretty competitive at 200 yards, and even 300, but at 500 yards, most of the better .223 shooters were scoring high 20s, while the top 6BR shooters in Custom Limited class were in the mid-40s. (Junior Nick Sinkus did, however nail a 40 at 500 yards with his factory .223 Rem — great shooting by the youngster.)

Sinclair Int’l has just released an all-new, super-wide bipod system for F-Class, Tactical, and Varmint shooters. The new bipod costs $165.00 in silver or black anodized finish.

Sinclair’s previous F-Class bipod was popular but shooters wanted a wider “wheelbase” and the ability to work with 3″-wide forearms. Sinclair’s new unit offers these features and much more. The new bipod is lower, lighter (36 oz.), and easier to mount than the previous model. The new unit attaches via a captured pin system that works fast and can’t get lost. After engaging the pin, two adjusting knobs then clamp the fore-arm onto a felt-lined bracket for a secure fit. The bipod will accomodate up to 3″-wide fore-ends (and even 3 3/8″ without canting adjustment).

Adjusts for Height and Cant Angle
The new Sinclair Bipod features a large rotating lever that allows you to adjust rifle cant angle easily. Vertical height adjusts from 5.5″ to 10.25″, and the leg heights are independently adjustable — an important feature when shooting on uneven ground.

The folks at Sinclair did their homework. This is a completely redesigned system that offers an easily-adjustable, highly stable platform in the field. Considering the engineering, and the quality of materials involved, the $165.00 price seems more than reasonable. The new Sinclair Bipod appears to be a serious rival to the Canadian “Ski” Bipod (shown below), at about one-third the price.

The Barnes Triple-Shock X-Bullet has long been considered one of the best hunting bullets for game hunters. The all-copper construction provides excellent expansion and very high weight retention. The absence of a lead core means this bullet is also legal in areas (such as parts of California) where lead-containing bullets are banned.

The big innovation in the new Tipped TSX bullet is the addition of a polymer tip. The tip increases the bullet’s Ballistic Coefficient (BC). Additionally, polymer-tipped bullets show less bullet-to-bullet variance in BC than do conventional bullets. More uniform BC can make your point of impact at long range more predictable, shot after shot.

The TSX bullet, like the previous Triple-Shock, has grooves, or “drive bands”, formed in the outer casing. This effectively reduces the bearing surface. The use of drive bands is a proven bullet technology that can reduce friction and barrel copper fouling, while allowing higher velocities for a given bullet weight.

The TSX bullet is available in these calibers and weights:

Richard Franklin sold his stock-making business to Greg West, but Richard is still making stunning, one-off custom rifles using laminated fancy woods such as Crotch Claro Walnut, Turkish Walnut, Curly Maple, Bloodwood, and burls of various types. One of Richard’s favorite sources for fancy woods is Northwest Timber, based in Oregon. NW Timber has one of the largest collections of highly-figured Claro Walnut and fancy Maple blanks in the country, including many “book-matched” sets that are ideal for a three-layer laminated stock. The two, mirror-image, book-matched pieces form the outer layers, with a central spine of contrasting wood.

When shopping for fancy wood for a laminated stock application, be sure to consider the length and thickness required. For a tri-laminated benchrest stock with a 3″ forearm, you’ll need a block at least 2.5″ wide and 32″ to 35″ long (depending on overall stock length). After sawing that will give you two 1 1/8″-wide slabs, so that a contrasting 3/4″-wide section of wood can be placed in the middle. Thinner blocks of fancy wood can be used in a 5-layer laminate. If you can’t find a block at least 32″ long, a contrasting end cap could be placed on the fore-end. However, Richard prefers to work with blanks that are long enough for the whole stock.

Above is a book-matched set from Northwest Timber in Crotch Claro Walnut. Note how there are two matching pieces, top and bottom.

This above photo shows how spectacular Quilted Maple can look when stained and finished with contrasting highlights. A popular material for fine musical instruments, Quilted Maple can look just as good on a gunstock (below).

Eight years into the 21st century, it’s easy for us to assume that our “latest and greatest” gun stock designs truly represent the cutting edge of technology and innovation. We forget that some of the founding fathers of benchrest devised some pretty interesting designs decades ago.

An intriguing piece of Benchrest history came up for sale on Gunbroker.com recently. This 25-lb “unlimited” benchrest rifle, chambered in .222 Remington, showcases many features that were ahead of their time. The action says “Al Weber of Lodi, Calif”, but it’s not clear whether Al built the unusual wood stock, or whether that was the brainchild of someone else. The action looks like it might be an early custom action. Perhaps our readers know more….

Forum member Dan Conzo notes: “View page 17 of the Ultimate in Rifle Precision (1958), by Whelen. Ralph Pride, a barrel-maker and competitor, is using a rifle that is a twin of this rifle. Pride also wrote highly of the Weber action. The round bottom action has heavy lugs, a wall thickness greater than any conventional action at that time, and an integral recoil lug, It has three guard screws (1/4 ” socket head type), and the one-piece trigger guard extends past the front guard screw. The top of action is what they called a strong back with the port held to a minimum and it has the squared off rear tang. This action seems to have spawned the older Hart actions and even the more modern actions by other makers of today.”

In the front is a metal sled with twin Delrin rails for improved tracking. Front rails have been used on 1K Heavy Guns for quite some time, but when rails like this were added to the underside of F-Class rifles that innovation was considered fairly radical.

In the rear is another tracking rail. Interestingly, the rear rail is a wide, “Twin Keel” or “catamaran” design. Presumably this twin keel design enhances stability while reducing friction. That’s a design we’ve just started to see on short-range BR rifles, and it has been hailed as “highly innovative”.

We wanted to showcase this Vintage BR rifle, to give credit to the early innovators. Our current high-tech stocks and actions borrow from many of their design ideas.

Many visitors to the site ask us, “I’ve got a .223 and .308. What will a 6BR give me that I’m not getting already?” Well first you will probably get consistently smaller groups than your current .223 or .308 rifle. Even with a Rem 700 or Savage action, a 6BR with a premium barrel and a high-quality chambering job should deliver 5-shot groups in the high twos to mid-threes, provided you do your job. Compared to a .223, the 6BR offers a much better selection of high-BC projectiles, and will deliver considerably more power on the target. Compared to the .308 shooting 168gr MatchKings, a 6BR shooting 105-107gr bullets offers better ballistics all the way out to 1000 yards. Plus the 6BR is just easier to shoot than a .308. Recoil is less than half of the .308 cartridge. Both the .308 and 6BR chamberings offer good barrel life, but the 6BR uses 50% less powder, saving you money. Here’s how the 6BR stacks up vs. a number of popular calibers:

Newcon Optik, based in Toronto, Ontario, Canada, produces many optics products for the Canadian military including laser rangefinders, image stabilizers, and night-vision gear. Newcon Optik also sells a line of laser rangefinders for consumers. Newcon claims that its rangefinders offer performance comparable to Leica, but at a much lower cost. The Newcon Optik LRM2000 Pro is designed to function out to 2000 meters, with a “reliable, all-conditions range” of at least 1500 yards. The LRM2000 Pro sells for $499.95 at SWFA.com, making it considerably cheaper than comparable models from Leica and Swarovski.

AccurateShooter.com has not been able to field test the LRM2000 Pro ourselves. For that reason it was not included in our Review of Laser Rangefinders done in 2007. However, we’ve handled the unit at SHOT Show and there are many features we like. First, it has a selectable reticle, offering a choice between a small rectangle and a cross-hair. By contrast, the $890.00 Swarovski Laser-Guide only offers a rather large aiming circle. Some hunters have complained the Swaro’s reticle is just too big for deer-sized animals out past 600 yards or so.

FEATURES
1 - Measurement result
2 - Units of measurement (Yards, Meters, Mils, Degrees)
3 - Low battery indicator
4 - Over 100m indicator (LRM 2500, LRM 2500CI Models only)
5 - Laser active indicator
6 - Target quality indicator (optional)
7 - Reticle (cross or rectangular selectable)

We also like the Newcon Optik’s shape and ergonomics. Sized 4.72″ x 4.8″ x 2.36″, the Newcon is flat and easy to hold, with non-slip rubber grip sections on both left and right sides. You can hold the brick shape securely with two hands, horizontally, like using binoculars.

By contrast, Leica went to an ultra-compact, vertical design for its latest CRF1200 rangefinder. The CRF’s small size makes the Leica easy to carry, but it is more difficult to hold the Leica stable when precise aiming is needed. With the Newcon Optik, you can set it flat on top of a case or rucksack and it’s easier to maintain a solid grip. The LRM2000 Pro also offers a built-in digital compass, a nice feature for anyone in the outdoors.

In the video below, Alex Rudi of Newcon Optik explains the features of the LRM2000 Pro model:

Unlike benchrest shooters, hunters need to be able to make shots with significant up-angles or down-angles. That whitetail buck may be poised on a ridgetop above you, or in a valley below. When making an angled shot, the hunter faces a complex ballistic solution. This is because the angle of the shot alters the effective ballistic distance to the target. Whether you shoot up-angle or down-angle, you must adjust your elevation “clicks” as if you are shooting a shorter distance. See the diagram below. The drop of your bullet is a function of gravity, which remains constant. When you shoot at a steep angle, the actual bullet travel over the ground will be less than the sloped distance to your target.

But how do you determine the flat-line or “gravity-corrected distance”? There’s a simple tool that will do the job: the patented Angle Cosine Indicator (ACI) invented by U.S. Army Veteran Ward Brien.

When you aim your rifle at an angle, the ACI shows the cosine value of your intended shot by means of a highly visible index mark. You simply multiply the true, sloped distance to your target by the cosine value (as a percentage), to get the corrected, flat line distance to target, i.e. the bottom leg of the triangle. Then set your scope’s elevation accordingly. For example, if you range the line of sight distance to your target at 400 yards, and the ACI shows a cosine value of 0.87 (for 30 degrees), then your flat-line “gravity-corrected distance” is 400 x 0.87 = 348 yards. Dial your elevation for 350 yards (from your come-up table) and you’re good to go.

This simple multiplication method works well for typical 100-300 yard hunting distances, but it’s not perfect. For longer-range shots, out to 1000 yards, some other factors come into play. The most accurate method for long ranges is to input the cosine number into ballistic software, such as Exbal Ballistic Targeting Software, that runs on a PDA or Palm Pilot. The software takes into account the fact that, during an angled shot, the bullet must still travel the full distance to target, and will have a longer time of flight than when covering the flat line distance. At very long ranges there can be as much as eight (8) MOA difference between the simple multiplication method and the solution generated by the ballistic software.

The Angle Cosine Indicator costs $109.95 from Sniper Tools. The ACI is made from aircraft grade aluminum, anodized flat black. Angles are laser-engraved onto the body in five (5) degree increments. The lens is water-resistant, shatter-proof, and shock-proof. Completely mechanical, there are no batteries or electronics to fail. For more info, visit SniperTools.com, or call (818) 359-0512.

Larry and Brenda Potterfield of MidwayUSA recently established the MidwayUSA Foundation, a not-for-profit public foundation designed to provide financial support for education and training in the areas of shooting, hunting, firearms safety and outdoor skills.

The Potterfields donated over half a million dollars as the first donation to the Foundation. “New shooters are the lifeblood of our industry,” said Larry Potterfield, President of MidwayUSA, a catalog and internet retailer of shooting and hunting products. “Bringing new shooters into the sport is critical to the future of the shooting sports.”

To this end, the Foundation’s first endowment is the Scholastic Shooting Trust (SST) Fund. Via the SST fund, an alumnus (or other interested party), can make a donation to a particular high school or college program. That donation will be used to support the designated school’s existing shooting program or to help launch a shooting program.

“Here is how the program works,” continued Potterfield. “I just used the Foundation Website to make a donation for the University of Missouri’s Shooting Team. A portion of the donation will be contributed to the Shooting Team, with the remainder left as endowment principal. Every year in perpetuity, the Shooting Team will receive earnings from the principal to use for the team’s operating expenses.” Contributions to the SST Fund can be made through the Fund’s website at www.ScholasticShootingTrust.org.
