For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

Chuck’s Pair of Pennsylvania Dashers
There’s been a lot of interest in the 6mm Dasher cartridge lately, so we thought we’d showcase a matched pair of Dasher rifles belonging to a Forum member. The 6mm Dasher began as a wildcat improved version of the 6mmBR Norma cartridge. The 6mm Dasher has been very successful in competition, and now factory Norma-made Dasher cartridge brass is available from Bullets.com.
Forum Member Chuck L. (aka “Ridgeway”) has created a handsome duo of 6mm Dashers for competitive benchrest and varmint matches in Pennsylvania. Both guns are built on Kelbly Panda RBLP actions, with Bartlein 8-twist barrels, and Shehane Laminated Tracker Stocks. However, the two rifles are not exact twins, as you can see. One, which we’ll call the Big Dasher, is built on a Shehane ST1000 Tracker stock. The other gun, the Small Dasher, sports Shehane’s “Baby Tracker” stock — a design used with great success by Richard Schatz. The Big Dasher, optimized for 1000-yard competition, also has a slightly longer freebore — 0.136″ vs. 0.104″ for the Small Dasher.
Specifications for the Dasher Duo:
Small Dasher (13.5-pounder): Chambered for 6mm Dasher with approximately .104 freebore and a .264 NK. (No way of knowing exactly since it freebore was done in a separate operation by Kelbly.) Components are: Shehane Baby Tracker stock, Kelbly Panda RPLB action, Bartlein 1:8″ LV barrel at 26 ¾”, Kelbly Rings, Weaver T36, Jewell trigger. The barrel was chambered by Kelblys and the stock was bedded, glued and balanced by a shooting buddy (Forum Member johara1). I clear-coated the stock with auto urethane. Total weight is 13 lbs., 4 ounces.
Big Dasher (1K Light Gun, 17-pounder): Chambered for 6mm Dasher with a .136 freebore and .264 neck (PTG Reamer). Components are: Shehane ST-1000 stock, Kelbly Panda RPLB action, Bartlein 1:8″ HV 5R barrel at 28″, Shehane +20-MOA rings, Nightforce NXS 12-42x56mm, Jewell trigger. The barrel work, pillar installation, and bedding was done by Dave Bruno. The stock was clear-coated by Chuck with auto urethane. Chuck also made the rear butt plate and balanced the rifle. Total weight: 16 lbs., 13 ounces.
Chuck tells us: “I don’t get out shooting competition as much as I want due to time and family, but when I do compete, I shoot a Groundhog match at Southfork Rifle Club in Beaverdale, PA. Info on Southfork Club events can be found at Southforkrifleclub.com. The Southfork match is basically a 100-, 300- and 500-yard match with one sighter the entire match and 5 shots at each yardage for score. The Small Dasher, with the shorter ‘Baby Tracker’ stock, was set up for the Southfork Rifle Club’s ‘Light Unlimited’ class which has a 13.5-lb max weight.” (Editor: ‘unlimited’ is a misnomer for a weight-limited category.)
Chuck adds: “The Big Dasher with the heavy ST-1000 stock is set up for 1000-yard benchrest matches in Light Gun class. I hope to shoot a couple 1K matches with it at Reade Range in southwest Pennsylvania. I am still in load development for this rifle since it was just finished in January. One ironic thing is, it shoots the same load I’m shooting out of the lighter gun rather well. The only difference between the two chambers is the freebore is roughly thirty thousandths longer on the 1K gun (Large Dasher). I will also shoot this at Southfork in the ‘Heavy Unlimited’ class.”
Dasher Case-Forming: Neck-Turn then Fire-form with Bullets Hard in Lands
To fireform, I turn my cases down to fit the chamber and stop where the false shoulder makes snug contact with the chamber. Fire-forming rounds are loaded up with a 29-grain charge of H4895 or Varget and a 108gr Berger bullet seated hard into the lands about 0.020″ past initial contact with the rifling. It takes about three firings to make a nice clean Dasher case with a sharp shoulder. I anneal about every 3-4 firings. I have many cases that have about 10+ firings on them and they are still shooting well. The primer pockets are a little looser, but still hold a primer.
Both Dashers Group in the Ones at 100 Yards
My main bullet for both rifles is the 107gr Sierra MK, loaded with Reloder 15 powder, Lapua cases and CCI 450 primers. My main load for the Small Dasher is 33.0 grains of Reloder 15. This load shoots in the ones at 100 yards. For the Big Dasher, I’m still working on a load, although the same 33.0 grain load shoots in the ones in the heavier gun as well. I’m still looking for more velocity and my ‘max’ node. So far, I’ve gone well above 33.0 grains of RL 15 without pressure signs, but that load produces vertical at 100 yards, so I’m going to tinker with the load until I see pressure or it starts to shoot.
The NRA’s American Rifleman showcased an interesting project this week — an upgraded Ruger American Rifle Predator in 6.5 Creedmoor. The video below shows how a laminated wood stock from Boyd’s Gunstocks was adapted for the Ruger. A Boyds Prairie Hunter model in gray laminate was selected. This was custom-bedded to the Ruger’s action using Brownell’s Acraglas.
All Ruger American Rifle models employ dual aluminum V-Blocks to support the action. These fit slots in the underside of the action. Boyds makes its own version of these V-Blocks which were installed in the Boyds stock to secure the action.
Project leader Joe Kurtenbach says the size, shape, and geometry of the Boyds V-Blocks is very accurate, so they fit the Ruger action well. To further support the action, Acraglas bedding compound was applied to the inside of the stock, after release compound was applied to the barreled action. With this DIY bedding job, the Boyds laminated stock is definitely an improvement over this original “Tupperware” factory stock.
DIY Bargain Hunter Upgrade
American Rifleman states: “The Ruger American has some great features—hammer-forged barrel, reliable action, crisp trigger — but many would not consider the molded, polymer stock to be among them. Luckily, there are aftermarket options to enhance the rifle’s utility and aesthetics. A durable, attractive stock from Boyds Gunstocks and some DIY action bedding, using Brownells Acraglas, is the next step in the precision-driven hunting rifle build.”
Choice of Gun and 6.5 Creedmoor Chambering
For this project, American Rifleman’s Joe Kurtenbach selected one of his favorite cartridges, the 6.5 Creedmoor. Introduced in 2007 by Hornady, the accurate, flat-shooting 6.5 Creedmoor has proven very popular with both hunters and tactical/PRS shooters. The Ruger American Rifle Predator was chosen for its affordable price, reliable action, and Ruger Marksman adjustable trigger.
In this video, Kurtenback explains how and why the 6.5 Creedmoor chambering and Ruger American Rifle were chosen for the Precision Hunter rifle build project.
If you are a gunsmith or work on firearms, you need to read this carefully. The Federal Government, acting through the Department of State Directorate of Defense Trade Controls (DDTC), has imposed significant new burdens on gunsmiths by expanding the definition of “manufacturing”. This is a big deal, as the Arms Export Control Act (AECA) and its implementing rules, the International Traffic in Arms Regulations (ITAR), require firearms “manufacturers” to register with DDTC and to pay a registration fee that (for new applicants) is currently $2,250 per year.
Previously, most small gunsmithing operations that did not export firearms were NOT subject to AECA/ITAR registration requirements. Now, by virtue of a DDTC “Guidance” ruling issued 7/22/2016, ordinary gunsmiths might be required to register as a manufacturer simply because they thread a muzzle or cut a chamber.
The NRA-ILA states: “DDTC is labeling commercial gunsmiths as ‘manufacturers’ for performing relatively simple work such as threading a barrel or fabricating a small custom part for an older firearm. Under the AECA, ‘manufacturers’ are required to register with DDTC at significant expense or risk onerous criminal penalties.” Read NRA-ILA Full Report.
Here is the key language in the DDTC’s “ITAR Registration Requirements – Consolidated Guidance” Ruling of 7/22/2016:
2. Registration Required – Manufacturing: In response to questions from persons engaged in the business of gunsmithing, DDTC has found in specific cases that ITAR registration is required because the following activities meet the ordinary, contemporary, common meaning of “manufacturing” and, therefore, constitute “manufacturing” for ITAR purposes:
a) Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;
b) Modifications to a firearm that change round capacity;
c) The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);
d) The systemized production of ammunition, including the automated loading or reloading of ammunition;
e) The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;
f) Rechambering firearms through machining, cutting, or drilling;
g) Chambering, cutting, or threading barrel blanks; and
h) Blueprinting firearms by machining the barrel.
Editor’s Comment: Does this mean that any stock-maker or stock supplier is an ITAR “manufacturer” under part 2(c)? Would installing a scope or accessory rail fall under part 2(a) as “equipment upgrading”? Would fluting a barrel be considered “manufacturing” under part 2(h)?
Impact of New Registration Requirements
As the NRA-ILA (Institute for Legislative Action) reads this, gunsmithing shops (even one-man operations) will now be subject to ITAR regulation though they export nothing: “These requirements apply, even if the business does not, and does not intend to, export any defense article. Moreover, under ITAR, ‘only one occasion of manufacturing … a defense article’ is necessary for a commercial entity to be considered ‘engaged in the business’ and therefore subject to the regime’s requirements.”
As a consequence, these new regulations may drive smaller gunsmithing services out of business: “DDTC’s move appears aimed at expanding the regulatory sweep of the AECA/ITAR and culling many smaller commercial gunsmithing operations that do not have the means to pay the annual registration fee or the sophistication to negotiate DDTC’s confusing maze of bureaucracy. [This is] likely to have a significant chilling effect on activity that would not even be considered regulated.”
Statutory Authority for Registration
The AECA’s statutory requirement for firearms manufacturers to register with DDTC is implemented in Part 122 of the ITAR:
§122.1 Registration requirements.
(a) Any person who engages in the United States in the business of manufacturing or exporting or temporarily importing defense articles, or furnishing defense services, is required to register with the Directorate of Defense Trade Controls under §122.2. For the purpose of this subchapter, engaging in such a business requires only one occasion of manufacturing or exporting or temporarily importing a defense article or furnishing a defense service. A manufacturer who does not engage in exporting must nevertheless register.

We know you guys like do-it-yourself (DIY) projects. And we also know that our readers like anything that helps a rifle sit more securely in the bags, and track better on recoil. Here’s a little accessory you can make yourself for pennies that will help rifles with conventional (non-benchrest) stocks ride the rear bag better.
This DIY Bag-Rider is simple in design and easy to make. The invention of Forum member Bill L. (aka “Nomad47″), this is simply a short section of PVC pipe attached to the bottom of a wood stock with a couple of screws. The back half of the PVC tube is cut at an angle to match the lower profile of the stock. Nomad47 painted the PVC Bag-Rider black for sex appeal, but that’s not really necessary.
In the top photo you can see Nomad47’s bagrider attached to a Savage varminter. In the photo below, the PVC bag-rider tube is fitted to an F-TR style rig with a green, laminated thumbhole stock. This rifle also features a Savage action with a custom barrel and “wide-track” bipod. (Note: to be legal in F-Class competition, the muzzle brake would have to be removed.)

Here’s a new barrel option for Savage shooters. Proof Research, a leader in composite barrel production, now offers “Pre-Fit” barrels for Savages. These barrels come chambered and threaded for Savage actions. Pre-Fits are easy to install — just spin them on, set the headspace with gauges, and tension the barrel nut. (Proof Research does recommend enlisting a gunsmith to help with the process.)
With a finished weight under three pounds, these new Pre-Fit barrels are much lighter than conventional all-steel barrels. Proof Research claims that they are “less than half the weight of comparably-sized steel barrels.” But you will pay dearly for that weight savings. As sold by Stocky’s Stocks, these Proof Research Pre-Fits cost $846.99, more than twice what all-steel Pre-Fit barrels from Criterion or Pac-Nor cost. Criterion Barrels currently charges $370.00 for a 26″ Savage or Rem/Age Pre-Fit.
Proof Research claims that its carbon-wrapped barrels shed heat faster than an all-steel barrel. Jason Lincoln, Proof Research’s VP of Engineering, claims that his company’s composite barrels can cool 50% faster than steel barrels, offering reduced point-of-impact shift during extended strings of fire. Is this marketing hype? We have yet to see a definitive test that validates the claims of enhanced cooling…
Proof Research Savage Pre-Fit Options Available
Initially the Pre-Fit barrels will be offered in a “Sendero” profile, very similar to an M24 contour. Available barrel lengths (up to 28″) vary by caliber/chambering (in some cases 24″ is all you can get). The following chamberings and twist rates are currently offered by Stocky’s Stocks:
Multi-time National High Power champion David Tubb has developed an impressive two-stage trigger for Remington 700 rifles, the Model T7T. Priced at $385.00, the T7T Trigger is a true two-stage design: first and second stages are independently adjustable for both weight and feel. Overall (combined stage) trigger pull weight can be adjusted from just under 1 pound to slightly over 3.5 pounds.
The new T7T is a quality product. We’ve used the T7T and it proved crisp, repeatable, and reliable. If you are looking for a two-stage trigger for a precision rifle, this is a good option. We like a two-stage trigger for PRS applications, and the T7T can be adjusted high enough for that role. Or, it can go all the way down to under a pound — low enough to suit most F-Class shooters.
If you are interested in the T7T, watch these two videos. The first shows how to adjust pull-weights for both stages. The second video shows how to modify your stock to provide clearance for the T7T.
This video shows how to adjust the new Tubb T7T two-stage trigger for Remington 700s:
T7T Trigger Installation Tips
While installation of the T7T may require minor modifications to your action, most gun owners with basic mechanical skills can install the T7T by themselves. Note: As installed, the T7T trigger (either Right-Hand or Left-Hand) also requires a companion T7T bolt release, which you can get from DavidTubb.com for $10.00.
This video shows how to modify your stock to fit the T7T trigger:

In our Shooters’ Forum, you’ll find a lengthy thread about accuracy problems with a Savage LRPV, chambered in 6mmBR. The gun would repeatedly split groups at 100 yards, and at 300 yards, the “flyers” would open up the groups to 1.5 MOA or larger. Interestingly, the factory test target (at right) showed a split group — not a good sign.
The gun’s owner, forum member LR_Shooter, tried a variety of tweaks: “I did this, done that… [changed] torque, tang floated, bedded action, recut chamber, and [adjusted firing pin]”. But nothing really helped. Frustrated, LR_Shooter asked his fellow Forum members for help. Much advice was proffered, including the novel idea of removing the middle action screw in the Savage 3-screw target action. Some of the advice proved helpful, but none of the suggested remedies produced a major improvement. This rifle, out of the box, tossed flyers and no amount of tweaking (or changes in shooting technique) really cured the basic problem. That is, until, the factory barrel got replaced…
New Criterion Pre-Fit Barrel Works Wonders
LR_Shooter acquired a Criterion pre-fit barrel from Jim Briggs at Northland Shooters Supply (NSS). These pre-fits are designed for easy installation with the standard Savage barrel nut. Wouldn’t you know it, with a new 30″ heavy-contour barrel on the LRPV, the gun started shooting way better. No more crazy fliers, no more split groups, no more excessive vertical. And the improvement came without any other major modifications. LR_Shooter reports: “I got a replacement barrel from Jim at NSS. It is a 30″ bull Criterion barrel. So far, without playing with torque screws and having my old setup… I’m very satisfied with the barrel I got. Now I have no problem getting [groups] under 0.25 MOA. Finally this thing can shoot!” The targets below, shot with the new Criterion barrel, speak for themselves. The left target was shot at 100 yards, while the target on the right was shot at 300 yards (very impressive).

Moral of the Story — Sometimes A New Barrel Really Is the Right Solution
All of us have struggled at times with a rifle that won’t live up to expectations. This Editor personally struggled for over a year with a .260 Rem Savage with a factory tube. The gun tended to split groups and the POI walked as the barrel heated. I tried one powder/primer combination after another, working through a variety of seating depths over many months. I was persistent. Out of stubbornness, I just believed that sooner or later I’d find the magic load.
Well folks, sometimes there’s really nothing you can do about a sub-par barrel. It is what it is. To really improve a gun’s accuracy (particularly a gun with a factory tube), you may need to open your wallet and get a quality aftermarket barrel. Spending months trying one recipe after another may simply be an overwhelming waste of powder, bullets, and your precious time.
Albert Einstein supposedly said: “Insanity is defined as doing the same thing over and over again, and expecting different results.” Well that sort of describes my efforts with my .260 Rem. Once I had enough evidence that my barrel split groups no matter what load combo (and seating depth) I tried, it was time to pony up for a new barrel. When I did finally screw on a nice PacNor 3-groove Supermatch, that Savage suddenly became a true tack-driver. As re-chambered in 6mmBR with the Pac-Nor, in calm conditions, my Savage will now consistently shoot in the twos with heavy bullets, and it can sometimes dip down into the ones with Berger 80gr flat-base bullets. The moral of the story here is simple — don’t waste weeks or months chasing your tail with a barrel that just won’t deliver (after a reasonable amount of testing). Save up for a custom barrel, get it chambered properly, and stop your cycle of frustration.
