Here’s a cleverly-designed new product that adds versatility to any rifle with a front sling swivel stud. This new Stud Rail Adapter (SRA) allows you to mount a Picatinny Rail on a sling swivel stud. With the SRA in place, you can attach any accessories that clamp to a Pic rail, such as lights, lasers, pistol grips, or rail-affixed tactical bipods. And look carefully — the SRA’s designers included a sling swivel at the inboard end of the unit. That way you can mount Picatinny-rail accessories and still use your carry sling.
Sold by Harrisbipods.com, the SRA Stud Rail Adapter retails for $47.85. NOTE: HarrisBipods.com is a web retailer. This is NOT Harris Engineering, the manufacturer of Harris bipods. HarrisBipods.com does sell the full line of Harris bipods and most Harris accessories. However, as far as we can tell the SRA is NOT made by Harris Engineering.
Comment: We think this adapter is a useful invention, particularly for those who might want to mount a light to a varmint rifle. Most hunting rifles have a front sling swivel stud and there is now a very wide selection of Picatinny-rail-mounted accessories.

The USA F-Class National Championships will be held October 28 – November 2, 2014 in Phoenix, AZ. Many top competitors are out practicing, perfecting their technique and their loads. Here’s a photo from our friend Paul Phillips, a member of the World Championship F-TR Team USA. Paul enjoyed the colorful fall foliage at his Michigan home range: “It was a great day to practice for the Nationals. My load and rifle are shooting great. Now I need to load 300 rounds with my recipe.”

Under Two Inches at 500 Yards
To be competitive at the Nationals, one needs a tack-driving rifle and an ultra-accurate load. Shown below is one of Paul Phillips’s load development targets at 500 yards. The total 5-shot group size is under two inches. Impressive. That’s with 200gr Bergers, Varget powder, and large primer Lapua brass. Paul tell us: “At the upcoming Nationals we will be competing at 1000 yards. The X-Ring is 5 inches at 1000 (equivalent to 2.5 inches at 500). We strive to be all in the X-Ring. However, wind is the big obstacle. A gust of wind can move you 1-2 feet away.”

Effects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 1 by Bryan Litz forBerger Bullets.
Many shooters are not aware of the dramatic effects that bullet seating depth can have on the pressure and velocity generated by a rifle cartridge. Cartridge Overall Length (COAL) is also a variable that can be used to fine-tune accuracy. It’s also an important consideration for rifles that need to feed rounds through a magazine. In this article, we’ll explore the various effects of COAL, and what choices a shooter can make to maximize the effectiveness of their hand loads.
Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI)
Most loading manuals (including the Berger Manual), present loading data according to SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) standards. SAAMI provides max pressure, COAL and many other specifications for commercial cartridges so that rifle makers, ammo makers, and hand loaders can standardize their products so they all work together. As we’ll see later in this article, these SAAMI standards are in many cases outdated and can dramatically restrict the performance potential of a cartridge.
Bullet seating depth is an important variable in the accuracy equation. In many cases, the SAAMI specified COAL is shorter than what a hand loader wants to load their rounds to for accuracy purposes. In the case where a hand loader seats the bullets longer than SAAMI specified COAL, there are some internal ballistic effects that take place which are important to understand.
Effects of Seating Depth / COAL on Pressure and Velocity
The primary effect of loading a cartridge long is that it leaves more internal volume inside the cartridge. This extra internal volume has a well known effect; for a given powder charge, there will be less pressure and less velocity produced because of the extra empty space. Another way to look at this is you have to use more powder to achieve the same pressure and velocity when the bullet is seated out long. In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short.
Figure 1. When the bullet is seated farther out of the case, there is more volume available for powder. This enables the cartridge to generate higher muzzle velocity with the same pressure.
When you think about it, it makes good sense. After all, when you seat the bullet out longer and leave more internal case volume for powder, you’re effectively making the cartridge into a bigger cartridge by increasing the size of the combustion chamber. Figure 1 illustrates the extra volume that’s available for powder when the bullet is seated out long.
Before concluding that it’s a good idea to start seating your bullets longer than SAAMI spec length, there are a few things to consider.
Geometry of a Chamber Throat
The chamber in a rifle will have a certain throat length which will dictate how long a bullet can be loaded. The throat is the forward portion of the chamber that has no rifling. The portion of the bullet’s bearing surface that projects out of the case occupies the throat (see Figure 2).
The length of the throat determines how much of the bullet can stick out of the case. When a cartridge is chambered and the bullet encounters the beginning of the rifling, known as the lands, it’s met with hard resistance. This COAL marks the maximum length that a bullet can be seated. When a bullet is seated out to contact the lands, its initial forward motion during ignition is immediately resisted by an engraving force.
Seating a bullet against the lands causes pressures to be elevated noticeably higher than if the bullet were seated just a few thousandths of an inch off the lands.
A very common practice in precision reloading is to establish the COAL for a bullet that’s seated to touch the lands. This is a reference length that the hand loader works from when searching for the optimal seating depth for precision. Many times, the best seating depth is with the bullet touching or very near the lands. However, in some rifles, the best seating depth might be 0.100″ or more off the lands. This is simply a variable the hand loader uses to tune the precision of a rifle.
The Western CMP Games and Creedmoor Cup Matches are underway right now in Phoenix, at the Ben Avery Shooting Facility. One of yesterday’s match winners was Dennis DeMille, General Manager of Creedmoor Sports, and a past National High Power Rifle Champion (2005). In the Military Rifle Match, Dennis showed how it was done, firing a 286-9X, to win the match. Below, shooting his 7.62×51 M1A, Dennis demonstrates his flawless form in standing.
Other Western Games shooters offered these comments about Dennis DeMille:
“CWO DeMille was my former OIC at Edson Range. I was part of the MCRD Shooing Team when he was the OIC as well. This man is Marksmanship — a true Gun Slinger and good friend.” — K.S.
“I have shot along side him before. [Dennis] just plain rocks in Service Rifle.” — Mike M.
“Other than the additional grey hair, some things never change.” — Mark T. V.M.
Sierra Bullets has just added extensive load data for the 300 AAC Blackout (300 BLK) cartridge. Developed for the AR15 platform, the 300 BLK offers AR shooters a large-caliber option in both subsonic and supersonic variants. The 300 BLK can be made from modified .223 Rem brass or necked-up .221 Fireball cases. We like to form our .300 BLK brass by necking-up the excellent Lapua .221 Fireball brass.
Sierra Has 5 Pages of Load Data for the 300 AAC Blackout. Here is one sample page:
Sierra Cartridge Comments: 300 AAC Blackout
The 300 AAC Blackout (300 BLK, or 7.62x35mm) was created by Advanced Armament Corp. and Remington in order to provide the military with a way to shoot .30 caliber bullets from the M4 platform with only a barrel change. It has since become popular for a wide range of uses including hunting and home defense.
The cartridge shares case-head dimensions and body taper with the .223 Remington. Not only does this allow for compatibility with existing magazines and bolts, but it allows reloaders to form 300 BLK brass from the vast supply of 5.56mm or .223 cases. However, since .223/5.56 cases need to be cut-down and reformed, it can be simpler to neck up .221 Fireball brass.
The 300 AAC Blackout is similar to previous wildcats, such as the .30-221 and .300 Fireball, as well as the proprietary 300 Whisper®. However the 300 BLK was the first SAAMI-approved (and standardized) cartridge of this type. Moreover, any company is free to make firearms or ammunition for the 300 BLK.
300 AAC Blackout is popular with hunters, who may not be allowed to legally hunt with .223 in their state, and who prefer .30-caliber bullets for medium-sized game. It provides similar effectiveness to the 7.62×39mm or the slightly more powerful 30-30 cartridges, while working in the more up-to-date AR15 platform. Effective range for hunting is about 100-150 yards.

Forster Products’ Heritage
I toured Forster Products’ Lanark, Illinois plant with Forster owners Robert Ruch and Rod Hartman. Forster Products was founded by the Forster brothers in 1935. The company’s first production was in the basement of their home. There, the brothers crafted the famous “Forster 99” model airplane engines, establishing a reputation for quality right from the start. In 1946 the company expanded into firearms reloading products, starting with headspace gauges, universal sight-mounting fixtures, and Forster’s famous case trimmers. All of these tools are still being manufactured and sold by Forster Product today.
In the 1950s, Forster’s reputation for precision allowed it to become a Rolls-Royce subcontractor making fluid and fuel control parts used in Rolls-Royce aircraft engines. Forster also manufactured fluid control parts used at the Hoover Dam and in the United States MX missiles. With this precision background it is no wonder that Forster Products holds an ISO 9001-2008 quality certification!
Forster Acquired Bonanza Reloading Co. in 1984
Forster reloading dies and presses came into being in 1984 when Forster purchased the Bonanza Reloading Company from its owner Clarence Purdie. Mr. Purdie designed the CO-AX press with its floating jaws, easy die installation and tremendous leverage. He also held the patents on the famous “sliding sleeve” featured in the Forster “Ultra” and “Benchrest” seaters. His sizing die design positioned the expander ball high up in the full length and neck dies so the case neck is supported as it resized while it is being withdrawn from the die. This design feature is also unique to the Forster brand. All of these innovations make Forster dies a quality product for producing precision ammunition. No wonder Carl Bernosky and John Whidden (NRA High Power and Long-Range champions) swear by them! It was great seeing that “Made in the USA” quality is still alive and well and that Bob and Rod along with their staff have such a great commitment to precision manufacturing and quality customer service.
Forster’s Time-Saving 3-in-1 Case Trimming/Chamfering Tool
Forster’s CFO, Robert Ruch, demonstrates the 3-in-1 Case Mouth Cutter tool in the video below. This unit trims the case to length, puts a 14-degree chamfer on the INSIDE of the neck, AND (last but not least), it cuts a 30-degree chamfer on the OUTSIDE of the neck. As you can see, the tool turns very smoothly (no chatter) and the job is finished in a few seconds. Forster’s 3-in-1 Carbide cutting tool works with all existing Forster case trimmers and other hand lathes with a .490″ shaft diameter. The tool typically sells for about $60.00 at major vendors, and Robert says it should last for a lifetime of use. The unit fits over the Cutter Shaft and easily secures with one set screw. The 3-in-1 cutter is available for five (5) calibers: .224, .243 (6mm), .264 (6.5mm), .284 (7mm), and .308.

Do you think your borescope is a state-of-the-art bore inspection device? Well think again. There is now something way more advanced than any optical borescope. A new laser-equipped scanning device can map the entire interior surface of a barrel bore. With this new technology you can now examine every land and every groove, millimeter by millimeter, from the chamber to the tip of the muzzle. The most minute flaw in a barrel can now be revealed.
The new device is called the BEMIS-SC™ (for Barrel Inspection Machine Small Caliber). Operated by Chesapeake Testing and Laser Techniques Company (LTC), BEMIS-SC performs non-destructive laser-based mapping of gun bores. The BEMIS-SC currently works with .22 caliber to .50 caliber (5.56 – 12.7 mm) barrels. The BEMIS captures thousands of highly accurate data points over the full length of a barrel. The inspection can be completed in mere minutes, with scan results displayed in graphical, tabular, and 3D visual formats. Here is a barrel cross-section, as scanned by the BEMIS-SC:

Until the 1980s, gun tube inspection had to be conducted by hand using a manual “star” gauge, a process that would take hours and provide minimal data. Electronic gauges were eventually developed along with the video bore scope, but these systems were still limited to very few, low-resolution data points. That has all changed with the BEMIS™, a huge leap forward in technology that is capable of rapidly capturing thousands of precise data points.
Chesapeake Testing commenced BEMIS-SC barrel inspection services in September 2014. Testing is performed in Chesapeake’s commercial barrel inspection laboratory, located in Belcamp, MD, minutes from the U.S. Army Aberdeen Proving Ground. While testing is currently limited to .22 to .50 caliber barrels, Chesapeake Testing will accommodate both smaller and larger calibers in the future.
“We have always focused on building our company around very unique technologies. BEMIS™ has changed the industry in regards to the inspection of weapon systems. We are excited to be an exclusive partner with LTC in this industry and look forward to contributing to the future of this technology,” says Jim Foulk, founder and president of Chesapeake Testing.

Frank Galli, aka “Lowlight”, runs the popular SnipersHide.com website. A while back, Frank completed a gunsmithing course with Robert Gradous. Frank recounts the learning process in an informative, nicely-illustrated article on the ‘Hide. Frank explains how he put together a new 6.5 Creedmoor tactical rifle using a Bartlein barrel, Bighorn Action (Rem clone with floating bolt-head), and a “lightly used” Accuracy International 1.5 chassis. The HD video below shows the process start-to-finish. READ Full Article.
During Frank’s “hands-on” training sessions with Gradous, Frank learned to thread and chamber a barrel, fit a recoil lug, and install the barreled action in the AI chassis. Chambering was done with great care: “We spent the better part of the day working the barrel. I feel this is a critical component and seeing the attention to detail in Robert’s approach confirmed it for me. When it came time to chamber Robert had a custom tight chamber reamer there for a 6.5CM but I’m shooting a tactical rifle, tight chambers aren’t for me, and this was clear, as out came the standard SAAMI reamer.”
Frank also learned how to modify an aluminum chassis: “the AI chassis had the recoil lug opened up, but it was opened in the wrong direction. This was going to require milling increasing the gap to at least a 1/2″ in size. Robert was really leery of this, but my attitude was, ‘it’s just a chassis and nothing a little Marine Tex can’t handle’.” Thankfully the chassis mod came out OK.
Once the barreled action was complete and the AI chassis was successfully milled, Frank applied a tan Cerakote finish to the barreled action. This would give a proper tactical look to the rifle, while providing superior corrosion resistance for the metal parts. To learn more about Cerakote finishing, check out the Cerakote Application Video, published last week in the Daily Bulletin.
When the rifle was complete, Frank took it out for testing with a variety of ammo, both factory fodder and handloads. There were some initial worries about accuracy as it took a while for the barrel to break in. A few sessions of bore cleaning were required before the barrel stopped fouling and then — like magic — the rifle started printing really small groups.
By the end of his load testing session, Frank was getting good groups with Hornady 120gr GMX factory 6.5 Creedmoor ammo, and really superb groups with handloads. The 120gr GMX ammo “was going 3100 fps with no ill effects”. The best handloads were approaching 1/4 MOA for three shots, and Frank’s load with Berger 130 VLDs shot even smaller than that: “In my opinion the load development we did was worth its weight in gold. Where else can you build in a rifle in two days, then go out and develop a baseline load using everything from 120gr ammo to 140gr ammo with a few in between? My favorite load and clearly the rifle’s too, was the [Berger] 130gr VLD. This gave us great velocity, awesome groups [with some one-holers] and really nice results at distance.”
Lowlight’s Gunsmithing Story is a ‘Must-Read’
We recommend you read Frank’s story. It shows that, with the right tools, and the supervision of a master smith, even a novice can produce an ultra-accurate rifle. For those of you who have considered taking a gunsmithing class, Frank’s successful experience with gunsmith Robert Gradous should give you plenty of motivation.

Forum member Erick C. (aka cncmill) has produced a very nice laminated stock featuring wood inlays. A tool and die maker from Pennsylvania, Erick is justifiably proud of his handiwork. Erick tells us: “Here is my latest build — just finished. The rifle features a Kelbly’s Atlas action, with Hawk Hill custom barrel chambered for the .284 Winchester. The stock is made from three types of wood: Birdseye Maple, African Padauk wood, and Wenge wood (for the dark stripes).” Erick explained that the Wenge inlays served a useful (as well as aesthetic) purpose: “I put the Wenge stripes in to fix two cracks in the Birdseye Maple. I was not sure about it at the time but it turned out well.”
Home-built Laminated Stock features three different woods.
