Shooting Prairie Dogs at extreme long range takes some highly specialized equipment. Forum Member VolDoc and his friends have taken long-range varminting to a whole new level. With his Savage-based, Hart-barreled 20 BR, VolDoc managed a verified 1,032-yard Prairie Dog kill, possibly the longest recorded with a .20-Caliber rifle. But that’s just part of VolDoc’s impressive precision varminting arsenal. Here we showcase three of VolDoc’s accurate rigs: his stunning English Walnut Diamondback 6BR/Dasher, his Nesika-actioned “Orange Crush” Dasher, and the 1K Prairie Dog-slaying 20 BR Savage.
Diamondback Switch-Barrel Rifle Specifications
The action is a Stiller Diamondback, drop-port. The custom stock is similar to a Shehane ST-1000, but crafted from 40-year-old English Walnut. [Editor’s note: the wood on this gun is gorgeous!] There are three barrels for the gun with three different chamberings: 6BR Brux 1:8″-twist HV; 6BRX Krieger 1:8″-twist HV, and 6mm Dasher Krieger 1:8.5″ twist fluted straight contour (no taper). The scope is a Nightforce 12-42x56mm, with 2DD reticle.
Comments: This rifle is a good study in comparison of the three different chamberings. On the same rifle platform (same stock and action), each of these barrels had killed prairie dogs over 1,000 yards. So if someone asks which is best, a 6BR, or 6BRX, or 6 Dasher, VolDoc says they are all effective. The improved cartridges will deliver higher velocities, which can be an advantage. On the other hand it is simpler to load 6mmBR brass right out of the box, and it’s easy to find an accurate load for the 6mmBR (see photo).
Nesika 6mmBR/Dasher Rifle Specifications
VolDoc’s “Big Orange Crush” rifle has a stainless Nesika ‘J’ action, with 2 oz. Jewell trigger, in a painted fiberglass Shehane ST-1000 stock. Originally a 6BR, the gun is now chambered as a 6mm Dasher with a .271 no-turn neck. The barrel is a 1:12″-twist Krieger fited with Vais muzzle brake. On top is a NightForce NXS 12-42x56mm scope with double-dot reticle. The double-dot gives precise aiming and lower dot can be used as an aming point, when you need a few more MOA of elevation in the field.
Comments: Big Orange Crush shoots 87gr V-Maxs into bugholes at 3,400 fps. VolDoc’s load with the 87s is very stout, more than 32 grains of Vihtavuori N-135 with Wolf SRM primers. Cases are full-length sized, with an 0.266″ bushing for the necks.
This 3400 fps load with the 87gr V-Maxs has accounted for hundreds of Prairie Dogs killed from 97 yards to 1,050 yards. The 87gr V-Max at this speed literally picks Prairie Dogs up and throws them 10 feet vertically and laterally. VolDoc reports: “The barrel now has more than 3,000 rounds down the tube and exhibits little throat fire-cracking and no loss of accuracy. I can’t explain why, it just hasn’t deteriorated yet. This rifle is my best-ever ‘go-to’ Prairie Dog rifle.”
Savage 20 BR Rifle Specifications
The action is a Savage Dual Port, with an aftermarket Sharp Shooter Supply (SSS) 4 oz. Evolution trigger. The stock is a modified Savage factory unit that has been pillar-bedded. The factory barrel was replaced with a 28″ Hart stainless, 1:9″ twist barrel fitted with a Rayhill muzzle brake. The gun is chambered in 20 BR with a 0.235″ no-turn neck. Kevin Rayhill did the smithing. To provide enough elevation to shoot at 1,000 yards plus, Ray fitted a +20 MOA Bench Source scope base. This +20 rail is very well-crafted, and made especially for the Savage Model 12.
Comments: VolDoc reports: “When I got the Savage back from Kevin Rayhill, it still had my 6 BR factory barrel on it, as I use it to compete in Factory-class regional matches. I put on the new 20 BR Hart barrel Kevin had chambered and quickly put in a full day of load development using the 55gr Bergers (0.381 G1 BC) and the 40gr V-Maxs. Both proved very easy to tune and I soon had my loads. My 55gr Berger load with runs about 3590 fps. Varget was very accurate with the 55s (see load dev. targets below).
The mild recoil of the 20 BR, along with a very good muzzle break (Rayhill’s design) enables me to spot every hit or miss myself. Kevin also re-contoured the underside of the Savage stock so it tracks straight back on recoil, also making seeing hits easier.”
The 20 Caliber 1000-Yard Prairie Dog Quest
Making the 1032-Yard Shot with a 20 BR by Dr. John S. (aka “VolDoc”)
This article covers my recent successful quest for a 20-caliber varmint kill past 1,000 yards. This may be a first — I couldn’t find anyone else with a confirmed 20-Cal Prairie Dog kill at 1000+. I started a thread on the Varmint section of the AccurateShooter.com Forum about building a 20 BR capable of 1,000-yard Minute of Prairie Dog accuracy and many said 20 Cal bullets just could not do it. Some came to my defense and said those that doubted had never studied the ballistics of the 20BR with the new Berger 55gr bullets now available. Well, folks, I can tell you, hitting a Prairie Dog at 1000 yards isn’t easy — but it IS possible. Here’s how it was done….
Gale-Force Winds and High Temps
After arriving at our Prairie Dog Ranch in Colorado, I soon realized my quest was going to be especially difficult because we had continual 40+ mph winds and 100° heat every day. We had a special place where Birdog and I had made many 1,000-yard+ kills in years past, so I knew the ideal location but needed a small window of opportunity either early morning or late afternoon. Based on past experience, I knew I needed about 21 MOA from my 100-yard zero to get to 1,000 yards. On the first day of the Safari, I shot the 20 BR in the 45 mph brutal winds and heat of 97°. But after about 20 shots, I connected on a dog and lifted him about three feet high. Well, that’s a start.
Winds Subside — Here’s Our Chance …
On the second day of our shoot, I had listened to the early weather forecast, so I knew that there was to be a brief period of light winds early in the morning. We were out on the Colorado prairie at daylight and the conditions were perfect. The sunrise was at my back and we had about a 10 mph tailwind. I looked through my Leica Geovid Rangefinder Binos and the Prairie Dogs were out for breakfast. I quickly ranged the targets and found a group at about 1,050 yards. The technique is to find the dogs, range them, click-up according to your ballistic chart and shoot.
My first shot was very, very close. I added about four clicks up and a couple of clicks left for windage and let another go. That shot threw dirt all over, but the dog didn’t even flinch. This is another good point to remember about long-range Prairie Dog hunting. To be successful, the dogs can’t be too skittish, because if they have been shot at even a few times, they will go down and stay down. So, you should have an agreement with those in your party as to where each member is going to be shooting and respect this boundary. Drive-by shooting style is OK if that’s your thing, it’s just not mine.
Hitting the Mark — Dead Dog at 1032 Yards
On the fourth shot, I saw the dog go belly up and kick its final throws. My quest for the 20-Caliber 1,000-yard Prairie Dog had become a reality. We confirmed the distance with our lasers at 1,032 yards. Our technique for retrieving a dead dog at that range is worth mentioning. When I killed that dog, I left it in the crosshairs of my Nightforce scope. My shooting buddy kept looking through the scope (of my gun) and guided me to the deceased dog using Motorola walkie-talkies. When I got to the dog I was jubilant. I marked it with my tripod and orange jacket, and we took some pictures. (See view through scope photo below). The 55gr Bergers require a center mass hit as they will not expand, especially at that range. I centered this dog in the head — his BAD LUCK, my GOOD.
After making the 1,032-yard kill, I shot many many other Prairie Dogs with the Savage 20 BR using the 40gr V-Maxs. The dog flights were spectacular — red mist and helicopters, counter-clockwise or clockwise on demand. I killed at least five at over 500 yards. I will not use the 55 Bergers on Prairie Dogs again since the quest is over. I will use the 40gr V-Maxs and 39gr Sierra BlitzKings for next trip’s 20 BR fodder.
Editor’s NOTE: Shelley Davidson passed away in 2008 after a courageous battle with cancer. He was one of the great innovators in benchrest rifle design. This article, written before Shelley died, showcases Shelley’s creative talents at their best. His “Tinker Toy” design will always be a tribute to Shelley’s fabricating skills and imagination.
Shelley Davidson — a brilliant innovator. R.I.P. Shelley — you will not be forgotten.
Shelley Davidson’s peers called his radical rifle the “Tinker Toy” gun. We call it revolutionary. Even now, 14 years after its creation, there’s nothing quite like it. This innovative, skeleton design threw conventional wisdom to the winds. Shelley readily concedes he “broke the rules” of benchrest rifle building. But this was inspired rule-breaking, because Davidson’s rifle shot like a house on fire. The Tinker Toy gun won its first matches, both for Score AND for Group. And this rifle also delivered many “zero groups” in Gene Begg’s Texas Tunnel. Hats off to Shelley for conceiving and building a truly radical rifle that was also wicked accurate and successful in competition.
Tinker Toy 30 BR — Radical As It Gets
Report by Shelley Davidson
Although I’m not big on naming rifles, my shooting buddies have christened the gun “Tinker Toy.” I can live with that as it does kind of look as if it was made with a Tinker Toy set.
Origins of the Project
This project began with some wild ideas I had in the fall of 2006 about using magnets to tune a barrel. My idea was to use one magnet on the barrel and another on the stock so they pushed against each other to counter gravity-induced barrel sag (and possibly) tame barrel vibration in a beneficial manner. The only way to test these ideas was to build the device and mount it on a gun. That meant I had to build a new rifle because there was no place to mount a magnet on the stock of a conventional benchrest rig. I had a Kelbly-stocked heavy varmint stock with a Michael Kavanaugh paint job on it. I didn’t think Kav would ever forgive me if I started drilling holes in one of his works of art. My light varmint was in a carbon fiber Scoville stock that costs about a grand. Drilling into the Scoville for an experiment just smacked of bad judgment. So, the magnet thing was my first motivation for designing a new stock. As long as I was building from scratch I decided to offset the barrel and action 0.75″ to the right to counteract the spin/torque from the bullet.
Although there’s nothing new here, my second motivation was to build a 30BR that could shoot in the 10.5 lb light varmint class in NBRSA. The magnetic tuner will automatically make this gun illegal in the IBS. The IBS has declared all barrel attachments un-safe and have outlawed them. I personally feel that the IBS really outlawed all barrel attachments to prevent experimentation and innovation. But at least we have NBRSA matches.
Designing the New Gun — Thinking “Outside the Box”
Once I’d decided to build a lightweight stock that could support experimental devices out near the muzzle, I started drawing up some rough plans. I also took a trip to Jerry Stiller’s shop in Wylie, Texas for a brainstorming session with Jerry, the maker of Viper and other Benchrest actions. Jerry is a school-trained mechanical engineer and thinks differently than I do. I came away from Stiller’s shop with my design roughed out and sketched on paper. The design violated several covenants of conventional wisdom for building competition BR rifles. For instance, two-piece stocks stress the action. Stress reduction is why most BR rifles are glued into the stock. Another myth is that metal stocks vibrate too much so wood or foam-filled fiberglass or carbon fiber are used.
Tinker Toy Rifle DESIGN FEATURES
Shelly Davidson’s Rifle was so innovative, that almost every feature, except the bare action, is very different than you’ll find on most Benchrest rigs. Accordingly we felt it would be useful to isolate and describe the key design features, from stem to stern. Click thumbnails to view FULL-SIZE PHOTOS.
Front Bracket with Magnetic Tuner
The tuner consists of one rare earth magnet attached to the stock and another attached to a barrel sleeve with the magnets oriented so as to make the magnetic force repel each other. The purpose is to counter “barrel droop” and, hopefully, dampen barrel vibration. The lower magnet is carried on a threaded shaft (with lock ring), allowing the magnet to be raised up and down to adjust the “up push” on the barrel.
Tubular Fore-Arm Supported by Brackets
Three brackets support two tubes, one on either side of the barrel. The rear-most bracket is sandwiched between the barrel and the action. Four inches forward (max distance allowed for barrel blocks) a second bracket grips the barrel. Near the muzzle a third bracket secures the ends of the tubes and holds the magnetic tuner. To allow barrel offset, the left tube is 1″ diameter tube while the right tube is 5/8″ diameter.
Offset Barrel The rifle rests on a 3″ wide plate attached to the underside of the two fore-end tubes. With the plate centered in the front sandbag, the barreled action is actually offset 0.75″ to the right (looking forward from the breech). The purpose of this offset is to keep more weight on the right side to counter the tendency of the rifle to torque counter-clockwise. Two different diameter tubes allow for the built-in offset.
Floating Action without Sub-Support or Bedding
On the Tinker Toy gun, the action serves as a load-bearing assembly, holding the barrel in the front, and the skeleton buttstock (or “keel”) in the rear. Shelley was told that accuracy would suffer if you stressed a benchrest action in this manner but that proved untrue. It is a very simple solution to building a rifle, and it eliminates the need to bed the action. The forearm attaches to the action via a bracket installed like a recoil lug.
Skeleton Rear “Keel” Affixed Directly to Action
Davidson’s Tinker Toy does not have a conventional rear buttstock. Instead there is low-profile, v-shaped metal “keel”, as Davidson calls it, that rides the rear bag. The keel is supported by a tubular backbone that attaches at the rear of the Diamondback action. At the butt end is an aluminum plate covered with bubble wrap that serves as a butt pad. The skeletonized rear section helps the rifle maintain a very low center of gravity.
Locked Scope with External Windage and Elevation Adjustment
Shelley ran an older Leupold 36X Benchrest Scope with front-adjusting objective. To eliminate slop or loose tolerances in the erector mechanism that could cause changes in point of impact, the internals have been locked up by Jackie Schmidt. To move the cross-hairs relative to the bore axis, Shelley has a special Jewell/Foster rear ring that allows a limited amount of lateral and vertical movement of the entire scope body.

Stiller Diamondback Action and Shilen 17-Twist Barrel
I had wanted to use an aluminum Stiller Cobra drop port with a 6mmBR bolt face but Jerry had none in stock and he estimated it would be a year before one was available. Although I’ve waited for up to a year for an action in the past, I wanted to build this rifle during the fall of 2006 while the weather was pleasant enough to work in my unheated and un-air-conditioned garage shop. Jerry did have a 1/2″ short stainless steel Diamondback in stock so I purchased it even though it would add 3 ounces to the gun compared to the aluminum Cobra. Three ounces is a lot of weight when you’re working with a 10.5-lb limit. I had a heavy varmint contour Shilen 17-twist barrel that would work nicely and I had a Jewell trigger on a rifle that I wasn’t using at the time. I also decided to use my Leupold 36X (locked-up by Jackie Schmidt) with the Jewell/Foster adjustable rings.
Building the Tube Fore-Arm and Brackets
I took a wild guess as to tubing thickness and settled on .035″ for the 1″ left fore-arm tube and .058″ for the 5/8″ right fore-arm tube. All of the flat stock and tubes are 6061 Aluminum. I did the lathe work and the mill work and every evening I’d put the parts together and think about the proper way to proceed.
When the parts were mostly made, I started thinking that this was a truly ugly rifle. I thought about painting it but that wasn’t a good option as many of the parts are designed to slide over others and glue together. Anodizing was the best answer so while looking on the Internet for local anodizing shops I Googled “Home Anodizing”. Sure enough there were a few sites that told about how to anodize at home. I picked up some battery acid from NAPA Auto Supply, some Rit Clothes Dye from Wal-Mart, and a bunch of distilled water from the grocery store. Using an old battery charger as my dc power supply I started anodizing and dying the eighteen parts that went into the stock. Although I had to strip and re-anodize some of the parts, the work turned out acceptable.
Putting it All Together–Lug-Mounting the Fore-Arm and Lots of Epoxy
The barrel contour had to be modified to work with the stock which attaches by way of a rear plate which mounts like a recoil lug and a plate that ties the barrel and the stock tubes together 4″ forward of the bolt face. The four-inch maximum distance is a NBRSA rule concerning barrel blocks.
The recoil lug-style stock mount is probably the only truly innovative thing I did other than the opposing-magnet tuner. Basically, the rear bracket is sandwiched between the receiver face and the barrel shoulder–positioned where a conventional recoil lug would go. I also added a brass ring (visible in photo) between the anodized bracket and the barrel. This was done to distribute loads over a wider surface area. (I was concerned that the bracket material was fairly soft and I didn’t want to crush it as I torqued the barrel in place.) After fitting the barrel and plates I glued the entire gun together using epoxy and various LocTite adhesives. The rest of the parts were assembled but I did not Loctite the scope bases since I thought I’d be disassembling the rifle for re-work after the first trials. That came back to bite me during later testing when the gun started shooting erratically and I went down a couple of blind alleys before finding the loose bases.
Range Testing–Results Are Very Positive
The first range session was a real shocker. Even though the wind was up to 10mph and twitchy, the rifle showed promise from the very first shot. I really didn’t expect that kind of performance without, at least, some rework. After sighting in, I shot five, 5-shot groups that, when averaged together, measured .223″. That’s good enough to win some benchrest group matches. But I wasn’t finished with the gun yet–I still wanted to try out my magnetic tuner concept.
The Magnetic Tuner
Next, I built the magnetic tuner. The tuner consists of one rare earth magnet attached to the stock and another attached to a barrel sleeve with the magnets oriented so the magnetic forces repel each other. In order to test the magnets and to determine if the rifle really shot as well as it seemed to, I took it to Gene Beggs’s shooting tunnel in Odessa, Texas. I spent two days at the tunnel testing loads and then installed the magnetic tuner. The gun shoots well with the magnets and shoots well without them. I suppose I can’t make any claims as to how much, if any, improvement the magnets make. Gene said that my gun was the most accurate rifle to be tested at his one-year-old shooting facility: “Shelley Davidson brought one of the most unusual rifles I had ever seen; he called it his ‘Tube Gun.’ And boy, did it ever shoot! It still holds the record in the tunnel as the rifle that shot more zeros than any other to date.” I definitely recommend Gene’s facility for testing and refining shooting techniques and loads.
Competition — Tinker Toy Won Both Score and Group Matches
Finally the big day arrived when I’d shoot the first match with my new gun. The North Texas Shooters Association was holding its first club match of the 2007 season. At the Denton, Texas matches we shoot a Score Match in the morning and a Group Match in the afternoon. The March event was at 100 yards and the April match will be at 200 yards and so on alternating throughout the benchrest season.
Match One–Tinker Toy Wins Score with a 250 – 17X
Since the gun is chambered in 30BR and that chambering is almost immune to tuning woes, I preloaded 130 rounds with H4198 powder and 118gr Cheek bullets. I used my SEB front rest and rear bag which are made by Sebastian Lambang in Indonesia. Everything came together, and Tinker Toy demonstrated that the accuracy it showed in the tunnel was no fluke. The gun shot great and I won the morning match with a 250, 17X. The day was quite windy and the next best shooter scored a 250, 15X. So I’d chalked up my first win.
Match Two–Tinker Toy Wins Group with a .2282″ Agg Tinker Toy won the afternoon group match I entered with a five-group Aggregate of .2282″. (The second place score was .2568″.) My groups were .149″, .197″, .243″, .302″ (oops), and .250″. You know how some folks say a 30BR can’t be competitive with a PPC? Well that .2282″ Agg won’t break any records, but it is good enough to win some regional registered BR matches. So this rifle has demonstrated an ability to win in both Score and Group matches. Obviously I have a very good Shilen barrel, great Cheek bullets and the rest of the components are doing their jobs as well. But, the stock is also working well.
Score Shooting vs. Group Shooting–The Rules
In a score match, the shooter shoots one bullet at each of five record targets, which are clustered on one target sheet. The Aggregate score of five of these targets determines the winner. If the shooter touches the 10 ring on all of his 25 targets he can score a “clean” 250 score. Usually there will be more than one shooter who scores a 250 so the winner is determined by the X-count. The 1/2″ 10-point ring has a 1/16″ dot in its center. Touching the X dot adds to the shooters X count. In short-range group matches, the shooter must try to put five bullets through the same hole. At each distance (100 or 200), five, 5-shot matches are scored, the group sizes are added together (MOA equivalent at 200) and the total is divided by five to arrive at an Aggregate score.

Stiller’s Precision Firearms (www.viperactions.com) has introduced a new line of billet stainless Octagon actions, dubbed the Spectre series. Designed primarily for tactical use, Stiller’s new Spectre Actions can also be used for long range hunting. Offered in .308 short action, .308 long action, and Magnum sizes, the black oxide-coated, octagonal Spectres feature a +20 MOA angled Picatinny rail milled into the receiver body.
MSRP for all Stiller Spectre actions is $1295.00 (price does not include separate, pinned recoil lug). Short-action Spectres are available right now, while the long-action and magnum versions should be in stock by December, 2013. To order, visit ViperActions.com or call 972-429-5000.
Spectres Designed to Fit Rem 700 Inlets with Minor Mods
The Spectres should fit most stocks designed for Rem 700-type actions (with minor modifications). Stiller’s Precision explains: “Spectres are octagonal stainless steel replacements for the Remington 700 series actions. The Spectre will fit most chassis including the Accuracy International series as a drop in replacement for the Remington 700 series actions. In standard stocks some minor inletting will be needed to clear the corners of the octagon.”
The short actions have .223 and .308 bolt-faces, while Spectre long actions have .308 or magnum bolt-faces. The .223 bolt uses the Sako-style extractor, while the others use a modified M16-type extractor. Spectre actions are only available with a straight handle. All tactical actions feature a one-piece-from-billet bolt and a screw-on knob. The standard bolt finish is black Iron Nitride QPQ (very durable).
Spectres Will Work with AI and AICS Magazines
Short-action Spectres have a magazine cutout for Accuracy International double stack magazines. They also work well with centerfeed-style detachable magazines such as the AICS. Stiller’s Precision offers detachable bottom metal systems that utilize both magazines. The short action Spectre will NOT function with the BDL [hinged floor plate] style magazine. The long Spectres have the standard Remington 700 style magazine cutout for either AICS style centerfeed detachable magazines or the BDL-style (hinged floor plate) magazine.

Pacific Tool & Gauge is now offering a Full-Length Re-Size Reamer and Die Blank Kit for $107.50. Yep, you read that right — you get a solid pilot (HSS) reamer AND the die body blank for $107.50, total. The reamer can be a standard-spec chambering or you can send in a file or print to have the FL re-size reamer match your current chambering. Some folks have wondered: “Can’t I just make a sizing die using my chambering reamer?” The answer is no. A resize die needs to be smaller than your actual chamber so that it can down-size the brass to ensure proper feeding and extraction. This kit from PT&G is a great way to get a custom sizing die for an affordable price. NOTE: You must still get a competent gunsmith to run the FL re-size reamer into the die body blank to create the finished die.
The resizing die kit (item N3861330) contains: One (1) Solid Pilot (HSS) Re-Size Reamer (excludes 50 BMG & Canon Type Reamers); and One (1) Caliber-Specific Die Blank. NOTE: This offer excludes 50 BMG and canon-type reamers.
PT&G 10% Discount for Owners of Stiller Actions
Here’s a great deal if you own a Predator, Tac30/300 or other Rem-clone type action from Stiller’s Precision Firearms. Last week, PT&G announced that it will give a 10% Discount on Remington-type PT&G parts used with compatible Stiller Actions. To qualify for the 10% discount, customers must provide proof that they own, or have purchased a Stiller Action for which there are compatible parts from Pacific Tool & Gauge. Please contact the PT&G sales staff for more information. Send email to pacpes [at] medford.net or call (541) 826-5808.

The Drop Port is a great feature for benchrest shooters. You can run a bolt without an ejector, yet your cartridge will extract smoothly and reliably each time you pull the bolt back. Stiller’s Precision Firearms pioneered the Drop Port design, and Jerry Stiller offers this as a popular option with his Cobra, Viper, Python, D-Back, and Diamondback actions. The Drop Port is amazing in its simplicity (watch video below). As you pull the bolt rearwards, the fired case slides downward into a funnel. As it tilts nose-down, the case rotates free of the six-o’clock extractor, falls nose first down the funnel, and finally exits through a hole in the bottom of the stock. Gravity does all the work.
S&S Panda Drop Port Conversion
Until recently, if you wanted a Drop Port, your only option was to purchase a Stiller action or engineer a conversion yourself. Now the owners of Kelbly Panda actions can enjoy drop-port functionality via a conversion performed by S&S Precision Rifles in Texas. The folks at S&S will mill a slot in the bottom of your action, and then install a drop funnel in your stock. The conversion work is done so well you’d think the Pandas were originally made as Drop Ports by Kelbly. Drop Port conversions will be available for popular small match cartridges including 22 PPC, 6 PPC, 6mmBR, 6BRX, 6 Dasher, 6.5 Grendel, and 30 BR (plus other wildcats in the BR family).
Conversion Will Be Costly — New Actions Are Best Candidates
This conversion will not be cheap. Because Drop Ports require a six o’clock extractor, you’ll probably need a replacement bolt for your Panda. S&S is in discussion with Pacific Tool & Gauge to provide these bolts. You can probably resell your existing bolt, but the upfront conversion cost could approach $400 with new bolt and labor. S&S hopes to announce firm pricing in 4-6 weeks. Don “Stick” Starks, S&S’s lead gunsmith, also cautions that this conversion is most cost-effective with Panda actions that have not yet been installed, or which are set up with pillars (as opposed to glue-ins). Stick explained: “If your Panda is already glued in, then we have to remove the action, mill the port, install the funnel, and then re-bed the whole thing. That’s going to substantially increase your cost. It’s more logical to do this on a Panda that has not yet be put in a rifle.”
In the video above, you can watch S&S Precision convert a Stolle Panda action to a Drop Port, and then see how the converted Panda functions. The rifle is a 30BR owned by FORUM member Truckincars, who also created the video.

Stiller’s Precision Firearms has been chosen to supply the action (receiver) for the new, updated MK 13, .300 Win Magnum sniper rifle for Crane Naval Weapons Center. The contract, valued at $2,000,000, calls for Stiller’s Precision to produce long actions for the latest version of the MK 13. The Navy could not simply upgrade its M40 sniper rifles from 7.62×51 to the larger, harder-hitting .300 Win Mag cartridge, because the M40 has a short action. The new MK 13 will employ a Rem-style long action in a modified Accuracy International Chassis. Current MK 13s feature an AICS stock, and a Knights forward rail mount or a MARS rail, with a Nightforce scope. Suppressors from various manufacturers are being tested for the latest MK 13.
MK 13 Action Will Eventually Be Offered to Civilian Market
Jerry Stiller tells us: “[For the MK 13 contract], we submitted samples and won out over the competition in a field type of test using all the submitted actions for consideration. The Navy is putting our action on new AI Chassis systems with new high-quality barrels. Hopefully, when we complete the first phase of the contract for them this year, we will make the same action available to the general public. We will keep everyone informed of what is available as it happens.”

Les Baer Custom (LBC) is a highly respected maker of “semi-custom” 1911 pistols and AR platform rifles. Now Baer moves into the precision bolt-action rifle market with impressive new offerings for 2010. Baer will sell two different bolt-guns, each fitted with a Stiller custom action and a cut-rifled barrel made in-house by LBC. Available chamberings (for both models) are .243 Win, .260 Rem, or .308 Win (later this year LCB will release a .338 Lapua). Remarkably, Baer guarantees these new guns can deliver half-MOA 10-shot groups with match grade ammo.
The new Les Baer Custom bolt-action rifles all feature a Stiller Tac 30 action with Picatinny rail, Wyatt precision floor plate with Wyatt detachable box magazine (DBM), along with a “match grade” 24″ cut-rifled, 5-groove LBC barrel. A Timney match trigger with 2.5-lb pull is fitted, and both action and barrel are coated in a matte-black Dupont S finish.
Two different Bell & Carlson composite stock designs are offered. The LBC Tactical Recon Bolt Action Rifle features a tactical-style stock, similar in appearance to the SAKO TRG stock. It has a vertical pistol grip, undercut toe, plus an adjustable cheekpiece and adjustable buttplate. MSRP for the “Tactical Recon” model is $3560.00.
If you want a lighter rifle with a more conventional stock, the LBC Tactical Varmint Classic features a varmint-style composite stock with a narrower fore-arm, “standard” wrist-grip shape, and a straight comb. There is a small hook in the underside of the buttstock. Like the “Tactical Recon” model, the “Tactical Varmint” features a Stiller action, Wyatt bottom metal/magazine, and 24″ cut-rifled barrel. MSRP for the “Tactical Varmint” is $3410.00.
New Les Baer Bolt-Guns have 10-shot Half-MOA Guarantee
We talked with Les Baer yesterday, and he told us that the prototype Baer tactical rifles have show outstanding accuracy during testing, producing some 1/2″ groups at TWO hundred yards. Accordingly, Baer is offering one of the best guarantees in the business. Both LBC tactical bolt-guns “are guaranteed to shoot 10-shot groups under 1/2 MOA with match grade ammo.”
The new LBC rifles will debut next week at SHOT Show in Las Vegas. We hope to get our hands on one for field testing. It will be interesting to see if the rifles can really put 10 shots inside one-half inch (center to center) at 100 yards.

Here’s a cool video created by Ed Cole and Roy Cole, twin brothers from Texas. In the video, the Coles demonstrate two Eliseo prone rifles, a bright green/orange Savage-actioned S1 and a pumpkin-colored R1 with Stiller Predator (Rem footprint) action. Both rifles are chambered for .223 Remington, and fitted with 31″ Brux cut-rifled barrels. In the video, the Coles shoot with slings and iron sights at targets 600 yards away. We have to say the day-glo colors on the Eliseo S1 will get anyone’s attention. WARNING: Loud music track and shooting sounds — turn the volume down if you are at work.
Roy Cole reports: “My orange ‘Longhorn’ R1 is a superb shooter. After breaking-in the Brux barrel, I took it to the Panola County 600-yard range. The first round was a low 9 on the target. A simple sight adjustment yielded a 10-shot string with eight Xs. With no load development the R1 just ate up the X-Ring. The most amazing thing is how the gun simply falls into your shoulder and fits! One of the greatest surprises of the gun is how nice the Timney tactical trigger is. It is not the most expensive trigger around but it performs as if it is! The Stiller Predator action works right out of the box. Put a barrel and a trigger on it and slip it into the tube stock and have the most fun that you have ever had. My brother Ed’s two S1 guns shoot just as well as my R1 does. His guns use Savage target actions with factory-issue Accutriggers.” Shown below is Ed Cole with another one of his Savage-actioned, Eliseo S1 match rifles. This example is a more ‘sedate’ Candy-Apple red.

Making the 1032-Yard Shot with a 20 BR
Hitting the Mark — Dead Dog at 1032 Yards
The recoil lug-style stock mount is probably the only truly innovative thing I did other than the opposing-magnet tuner. Basically, the rear bracket is sandwiched between the receiver face and the barrel shoulder–positioned where a conventional recoil lug would go. I also added a brass ring (visible in photo) between the anodized bracket and the barrel. This was done to distribute loads over a wider surface area. (I was concerned that the bracket material was fairly soft and I didn’t want to crush it as I torqued the barrel in place.) After fitting the barrel and plates I glued the entire gun together using epoxy and various LocTite adhesives. The rest of the parts were assembled but I did not Loctite the scope bases since I thought I’d be disassembling the rifle for re-work after the first trials. That came back to bite me during later testing when the gun started shooting erratically and I went down a couple of blind alleys before finding the loose bases.
