In 2016, Hornady will introduce new hunting and match bullets with high-tech, heat resistant tips. Hornady developed the new “Heat Shield” bullet tips after Doppler Radar testing showed that the Ballistic Coefficients (BCs) of old-style tipped bullets were degrading in flight in an unexplained manner. Hornady’s engineers theorized that the old-style plastic bullet tips were deforming in flight due to heat and pressure. Hornady claims this problem occurred with high-BC (0.5+ G1) tipped bullets from a variety of manufacturers. Hornady’s testers believed that, after 150 yards or so, the tips on high-BC bullets were actually melting at the front. That enlarged the meplat, resulting in increased drag.*
Consequently, Hornady developed a new type of bullet tip made from a heat-resistant polymer. Further long-range Doppler Radar testing seemingly confirmed that bullets equipped with the new tips did not suffer from the BC loss previously found. This allowed the bullets to maintain a higher, more consistent BC during the entire trajectory. The end result is a bullet with reduced vertical dispersion at long range (or so Hornady claims).
New Hornady ELD-X Hunting Bullets
For 2016, Hornady will bring out two lines of projectiles using the new tips. The first line of bullets, designed for hunting, will be called ELD-X, standing for “Extreme Low Drag eXpanding”. These feature dark red, translucent, heat-resistant tips. With interlock-style internal construction, these hunting projectiles are designed to yield deep penetration and excellent weight retention. Hornady will offer seven different ELD-X bullet types, ranging in weight from 143 grains (6.5mm) to 220 grains (.30 Cal):
NOTE: We don’t know if the stated BC values are based on drag models or actual range testing. These new ELD-X hunting bullets will be loaded into a new line of Precision Hunter Ammo for a variety of popular hunting cartridges.
New Hornady ELD Match Bullets
Along with its new hunting bullets, Hornady is coming out with a line of ELD Match bullets as well. Hornady’s engineers say the new molded “Heat Shield Tip” should be a boon to competitive shooters: “You can’t point up that copper [tip] as consistently as you can mold a plastic tip. With the ELD Match line, and the Heat Shield Tip technology… we now have a perfected meplat. These bullets allow you to shoot groups with less vertical deviation, or less vertical stringing, because the bullets are exact in their drag [factor].” There are currently four bullets in the ELD Match line:
Hornady will offer factory ammunition loaded with ELD Match bullets, starting with 6.5 Creedmoor ammo loaded with the 140gr ELD, and .338 Lapua Magnum ammo loaded with the 285gr ELD.
Better Tips Make a Difference — But other Factors Are Important
Hornady claims that its new Heat Shield Tips are more uniform than the meplats on conventional jacketed, hollow-point bullets. This, Hornady says, should provide greater bullet-to-bullet BC consistency than is possible with conventional, non-tipped bullets.
We have heard such claims before. Plastic tips are good, so long as they are inserted perfectly in the bullet. But sometimes they are crooked (off-axis) — we’ve seen that with various brands of tipped projectiles. Other factors will affect bullet performance as well, such as bullet weight, bullet diameter, and bullet bearing surface length. Even with perfectly uniform bullet tips, if bullet weights or diameters are inconsistent across a sample, you can still have accuracy issues (and pressure-related velocity variances). Likewise, if the bearing surface lengths vary considerably from one bullet to the next, this can increase velocity spread and otherwise have a deleterious effect on accuracy.
So, overall, we think Hornady has probably engineered a better bullet tip, which is a good thing. On the other hand there are many other factors (beyond tip uniformity) involved in long-range bullet performance. It will be interesting to test the new ELD Match bullets to see how they compare with the best hollow point jacketed bullets from other manufacturers.
MORE TECHNICAL DETAILS
* Hornady’s Chief Ballistician Dave Emary authored a technical report based on the Doppler Radar testing of a variety of tipped Bullets. CLICK HERE for Emary Report. Here are some of the report’s key observations and conclusions:
After early testing of prototype bullets it was observed that all currently manufactured tipped projectiles’ drag curves were convex, not concave and that abnormally low ballistic coefficients were being observed over long ranges. The drag was rapidly increasing at high velocities.
At this point extensive testing was done with all types of commercially-available tipped projectiles. They all exhibited this behavior to a greater or lesser extent depending on their ballistic coefficient and launch velocity. Most projectiles exhibited BCs relatively close to published values for 150 to 200 yards of flight. Beyond these distances they all showed BCs substantially below published values.
It was obvious that something was changing in the tipped projectiles to cause a rapid increase in drag at higher velocities. The drag increases were most noticeable from 100 to about 500 yards. Drag increases stopped at velocities below approximately 2,100 fps. This behavior was not observed with hollow point or exposed lead (spitzer) style designs. The problem magnified as the velocity was increased. The problem was worse for heavier, higher-BC projectiles that maintained higher velocities longer. After some consideration the answer was obvious and one that several people had wondered about for some time but had no way to prove their thoughts.
The tip of a bullet at 3,000 fps will see temperatures as high as 850 degrees F and decreasing as
the bullet slows down. These temperatures on the tip were a known fact. What wasn’t known was how long it would take at these peak and decreasing temperatures for the polymer tips to begin showing effects, if at all. As it turns out it is within the first 100 yards of flight. Currently-used polymers in projectile tips begin to have properties like rubber at approximately -65 to 50 degrees F and will melt at 300 to 350 degrees F, depending on the exact polymer.
All current polymer-tipped projectiles have tips that are at best softening and deforming in flight and under many circumstances melting and badly deforming. To cut through a lot of technical discussion the problem becomes worse at higher ambient air temperatures (summer) and higher launch velocities. Projectiles that have a high BC and retain velocity well see higher stagnation temperatures for longer lengths of time and have greater degradation of the tip. Simply put it is a heat capacity problem –temperature times time. This makes BCs for current tipped projectiles a rough average over some distance, dependent on atmospheric conditions and muzzle velocity, and does not allow the accurate prediction of downrange ballistics much beyond 400 yards.
Nightforce has announced a limited re-release of its NXS 2.5-10x24mm scope, with enhancements. The 2.5-10 NXS has been discontinued since 2008, but has been requested by customers for several years due to its small size and successful use with the Mk12 5.56 Special Purpose Rifle (SPR) program.

The late Bill Myers was recognized as one of greatest rimfire smiths who ever lived. Myers crafted many match-winning, record-setting rimfire benchrest rigs. Here we feature one of Bill’s most interesting creations — a clamping action that allows a rimfire barrel to be indexed (rotated) around the bore axis.
Bill was a creative thinker, and his own exhaustive testing has convinced him that barrel indexing can enhance accuracy in rimfire benchrest guns. Myers did acknowledge that, particularly with a very good barrel, the advantages of indexing may be subtle, and extensive testing may be required. Nonetheless, Myers believed that indexing could improve rimfire accuracy.
Indexing with the Myers’ Clamping Action
To index the barrel, Myers simply loosens the three clamping-bolts and rotates the barrel in the action. Because there is no thread to pull the barrel in or out, the headspace stays the same no matter how much the barrel is rotated. In other words you can rotate the barrel to any position on the clockface and the headspace remains unchanged.
The Challenge of Barrel Indexing With a conventional barrel installation, employing a shoulder with a threaded tenon, it is difficult to index the barrel. Even with a cone breech (photo right) that eliminates the problem of extractor cuts, you’d have to use shims to alter the barrel index position, or otherwise re-set the shoulder each time you screwed the barrel in further.
Clamping Action Allows Barrel to Be Rotated to Any Position
Bill has come up with a masterful solution to barrel indexing. He designed and built his own prototype custom action that clamps the barrel rather than holding it with threads. The front section of the action is sliced lengthways, and then clamped down with three bolts. A special bushing (the gold-color piece in photos) fits between the barrel and the action. By using bushings of different inside diameters, Bill can fit any barrel up to an inch or so diameter, so long as it has a straight contour at the breech end. To mount the barrel, Bill simply places the fitted bushing over the barrel end-shank, then slips the “sleeved” barrel into the front end of the action. Tighten three bolts, and the barrel is secure.
Dave Diana is a clever fellow. He not only fabricated his own wireless Target Cam system, but he invented a mount that places the receiver/monitor unit conveniently next to his bench rifle. The hooded view-screen actually mounts to his SEB front Rest via a bracket. The monitor unit includes wireless receiver and a short directional antenna (see below):
Dave says his new CCTV monitor bracket on the SEB NEO rest is “working as planned”. However, after taking these photos, Dave did make a modification. Dave explained: “I found moving the monitor over to the left-hand side was more shooter-friendly. I can stay in a natural shooting position, look at the screen, see my windflags and shoot with little movement. The next task is to add a coffee cup holder somewhere to house my group tightener double expresso!”
Target Cam Monitor Has Built-In Receiver
Dave built a very nice system. He tells us: “The security camera is a 27x power zoom camera housed in a weather proof case that also houses the wireless transmitter. The monitor has a built-in receiver, and I am running spiral polarized antennas on both ends. The system will run all day long on the waterproof-cased, game-camera batteries.”
Here are the internals of the wireless camera system. Note the antenna at right.
Here is the entire system, with monitor/receiver placed conventionally on a tripod. Batteries are housed in waterproof plastic cases.
If two barrels are better than one, then why not three? That’s the thinking behind the exotic new BD14 from Blaser, unveiled at the 2014 IWA Show in Germany. This “bockdrilling” three-barrel firearm works as a shotgun, large-caliber rifle, and small-caliber rifle all in one. Even with all those barrels, the BD14 is relatively light, at 3.3 kg (7.26 lbs) without optics. That makes this a nice, carry-around gun for stalking. As you’d expect from Blaser, the twin triggers are crisp and precise, with a pull weight of just 1.43 lbs (650 grams). The front trigger is for the large-caliber rifle barrel, while the rear trigger works both the shotgun and small-caliber barrels, via a tang-mounted selector. Sorry, we don’t yet have a USA-market price on this example of gun-making exotica, but you can bet it will be expensive.
Here’s what Blaser USA has to say about its unique three-barreled BD14:
“The ‘Bockdrilling’ is, put simply, an over/under (O/U) rifle-shotgun combination with a smaller caliber rifle-barrel… on the side. The barrel arrangement [allows] for an extremely slender receiver, making the BD 14 exceptionally huntable.
The brand new Vertical Block Lockup…has been filed for patent. It combines an extremely compact and solid block lockup in a closed system within the monoblock with the comfortable handling of a classic break-action rifle.
The double lock permits, if needed, a rapid second shot, the front trigger always releasing the large rifle-caliber. The … barrel selector actives the shotgun barrel when in position ‘top’ and activates the smaller rifle caliber in position ‘bottom’.”

If you’ve been following the tactical message boards, you’ll hear a lot of buzz about FrogLube CLP. Among the zillions of gun cleaner/lubes on the market, FrogLube stands out for its ability to work well even in challenging environments. Intended for U.S. Navy SEAL operators’ use in extreme environments, FrogLube was developed by Larry Lasky (Captain, USN retired), a former Navy SEAL officer. FrogLube’s blend of ingredients has been extensively field tested. The makers of FrogLube claim that fouling is dramatically reduced in FrogLube-treated firearms. FrogLube is a decent carbon-cutter and it also provides protection against rust and corrosion (though there are better rust preventers on the market, such as Eezox).
NOTE: Don’t expect FrogLube to remove copper fouling in the barrel — you’ll need a real copper solvent, such as Montana X-Treme. Overall, though, as a general purpose CLP, FrogLube performs well.
FrogLube is now available from major vendors, including Amazon.com and MidwayUSA. Notably, FrogLube is a “green” product that has received the USDA’s BioPreferred designation. On Amazon.com, a 5-piece combo kit with CLP liquid, CLP paste FrogLube, and FrogLube Solvent sells for $30.95 with FREE Shipping (on orders over $35). Amazon’s customers have raved about this stuff:
I was introduced to this product by a Sig armorer. I tried it. I loved it. It works. Period. Just like everyone else is saying here. Here is my break down of it as a CLP. The “C”: I have found that putting it on warm metal makes it work great…just like they say. I rub the paste on, let it sit and penetrate. A few minutes later….wipe it off. Clean enough to eat on. I even tried it on my mountain bike chain and components after running out of degreaser. Worked better than anything I have ever tried. The “L”: Once you use it on the parts you will notice it’s still there, having saturated the parts. Great for lube and goes a long way. The “P”: I hunt waterfowl in very rugged and sloppy conditions. The thing about this product is that when they say it saturates the metal, it truly does. Great protective features. It’s still on there and after all that moisture not speck of rust anywhere, unlike even the best of of other CLPs. — J. Zabick
Crazy Good — This stuff is amazing. I use it on my knives, razors and, of course, guns. It smells great, leaves no oily residue and cleans like nothing else I have used. Get the paste and the oil because sometimes the oil is called for and sometimes you need the paste. Can’t recommend it enough. I have already ordered more. — K. Chariton
Here’s a unique product that may be useful for practice sessions at 400 yards and beyond. Birchwood Casey now offers high-contrast, White/Black versions of its popular Shoot-N-C targets. There are four types of Shoot-N-C White/Black targets: 8″ Bulls-Eye X (#34802), 12″ Bulls-Eye X (#34019), and 12″ multi-diamond target (#34219), and 12″ x 18″ silhouette (#34615).
On all White/Black Shoot-N-C target types, the target background is all-white, and a large black “halo” or circle appears around each bullet hole. This makes the bullet impact much easier to see at long range. Normally it is very difficult to see 6mm (and smaller) bullet holes past 500 yards or so, unless conditions are absolutely perfect. At 800 or 1000 yards it can be nearly impossible to see even 30-caliber bullet holes in conventional paper targets. With these new white/black Shoot-N-C targets the large black ring surrounding each hit can be seen fairly easily, even at extreme ranges. NOTE: These targets work great with a target-cam — even if you have a monochrome monitor.
BIG news in the shooting sports industry — Ruger has entered the ammo business. Ruger now offers high-tech handgun ammunition, using licensed polymer-composite, lead-free bullet technology. According to the Shooting Wire: “Ruger’s new lead-free ammunition will be produced under a licensing agreement with Savannah, Georgia-based PolyCase Ammunition.”
Ruger’s new ARX line of lead-free ammo features injection-molded bullets that are much lighter than conventional projectiles, caliber by caliber: 56 grains for .380 ACP, 74 grains for 9x19mm, 107 grains for .40 SW, and 114 grains for .45 ACP. The lighter bullets fly faster, but ARX ammo still offers reduced perceived recoil.
Ruger ARX Ammo with Injection-Molded Matrix Bullets
The fluted projectiles are injection-molded from a copper/polymer matrix. This offers many advantages. First, being completing lead-free, these bullets can be used at indoor facilities that prohibit lead-based ammo. Second, because the composite bullets weigh 30% less than comparable lead-based projectiles, shooters experience noticeably less recoil (even though velocities are higher). Third, the composite matrix bullet has low-ricochet properties. When these bullets strike metal, they are designed to disintegrate (into a powder), rather than ricochet. This makes them well-suited for indoor use, or use with metal plates.
Shooting Wire Editor Jim Shepherd reports that ARX ammo delivers on its low-recoil promise: “Having spent time testing the PolyCase ammunition (largely in Ruger firearms), I know the reduction in felt recoil isn’t just hype. While firing PolyCase ARX ammunition in calibers ranging from .380 in small concealed carry pistols (including a Ruger’s LCP) up to .458 SOCOM in modern sporting rifles, the lessened felt recoil was noticeable.”
PolyCase Molded Bullet Design Technology
For over a century most bullets have been mass-produced with a process called cold-forming. Lead and copper were shaped with brute force in punches and dies to create projectiles. While this is still a viable and effective way to produce bullets, other manufacturing methods are now available. By applying injection-molding technology, Polycase has developed a new type of bullet that has many advantages, as least for handgun applications. Bullets weigh approximately 70% as much as lead bullets with similar profiles. Lighter weight means higher velocities and less recoil. In addition, PolyCase bullets are lead-free, and low-ricochet — two qualities important for indoor and close-range training. The injection-molding process also reduces weight variations (compared to cast lead bullets), and ensures excellent concentricity. Molding also allows unique shapes that are impossible to produce with conventional bullet-making methods (see photo).
Powder Valley Inc. (PVI) is now carrying Shooters World-branded powders produced by the Czech enterprise Explosia A.S., which has produced propellants since 1920. Powder Valley will initially be offering four new Shooters World propellants: Clean Shot, Heavy Pistol, Match Rifle, and Blackout. These are canister-packaged forms of the popular Lovex propellants sold in Europe. These powders are very affordable — they cost just $19.95 per pound at PVI. For other pricing and ordering information go to PowderValleyInc.com. Match Rifle, Blackout, and Clean Shot are all currently in stock at PVI.
Shooters World says: “We have received nothing but praise about the quality of these [Lovex] propellants. Because of this, we are very confident in how our canister propellants will fare in the reloading market. We have had many competitive shooters using our product[.]”
The following descriptions of Shooters World propellants have been provided by the manufacturer. Since AccurateShooter.com has not tested any of these powders yet, we cannot verify any particular claims:
Shooters World Powders — Manufacturer’s Product Descriptions
Match Rifle propellant is our canister form of Lovex D0 73-06 propellant. It is similar in burn speed to Accurate® 2520 and CFE™223. It holds the broadest utility across all moderate rifle propellants. The propellant gas generation rate is appropriate for cartridges of the light to heavy sectional density .223 Remington and .308 Winchester. It can load the 55 grain .223 Rem, as well as the 77 grain .223 Rem. It loads the 150, 168, and 175 grain .308 Winchester, and loads all .30-30 combinations. It works in .30-06, in 7mm-08, and even in the .22-250.
Blackout propellant is our canister form of Lovex D063-02 reloading propellant. It is slightly slower in burn speed than Accurate 1680®. The propellant gas generation rate is superior for subsonic 300 Blackout, 7.62×39, and some straight-walled rifle cartridges, where rapid transformation from powder to gas is desired. You would be hard pressed to find a subsonic 300 Blackout propellant that will give you the cycling reliability of the Shooters World Blackout.
Clean Shot propellant is the canister form of Lovex D0 32-03 propellant. Ballistic results for this propellant show it to be highly versatile, with low residue in a myriad of pistol cartridges. The burn rate is similar to Accurate No. 2®. Additionally, we have tested this propellant in shot shell, and found it to be exceptionally clean and consistent in velocity. This propellant can be used in virtually all pistol cartridges. A spherical propellant, it meters through charge plates extremely consistently and will work with a high-speed loader with very good flow. This propellant contains flash suppressant and is optimized for .45 ACP, 38 SPL, some standard velocity 9mm, some .40 S&W applications, reduced loads in .357 magnum, .44 magnum, and others.
Heavy Pistol propellant is our canister form of Lovex D0 37-02 propellant. It is similar in burn speed to Accurate® No. 9. The gas generation rate is appropriate for cartridges of the magnum pistol family and the .300 AAC Blackout, supersonic with light bullets. It does contain a level of flash suppression, incorporated into the propellant. A spherical propellant, it meters through charge plates consistently and will work with high-speed loaders with very good flow. This propellant is bracketed on the fast side by D0-37-01 (similar to Accurate® No 7), and on the slow side by D0-63-02 (similar in burn speed to Accurate® 1680).
Technical Information — CIP vs. SAAMI
Shooters World is in the process of developing reloading data based on SAAMI/ANSI standards. This data will be published on the Shooters World website, as it is generated and proofed in SAAMI test barrels, and compared against SAAMI reference ammunition. Hand-loaders can also reference information in the Lovex Reloading Guide, which has data tested to CIP (Commission Internationale Permanente) standards.
Note that Shooters World has maintained the nomenclature of the Lovex propellants on its reloading canister bottles. Shooters World did this to ensure that reloaders would have maximum access to reloading data — both from European and American standards. Shooters World says: “The charge weights and pressures reported in the Lovex Reloading Guide have been found very reliable”.
The main difference between CIP data and SAAMI standardization has to do with barrel length. CIP barrel length standards and SAAMI barrel length standards do not necessarily correspond. Therefore, the velocities reported in the Lovex Reloading Guide may not directly relate to USA standards. As is always the case, any reloader should start the load development process at a safe “starting charge”, and slowly increase charge weights to desired performance levels. Never exceed a maximum published load.
Q: What is the most popular gun book ever published?
A: That distinction goes to the Shooter’s Bible, which has sold over 7 MILLION copies since it was first published over 80 years ago.
Set for October 2015 release, the 107th Edition of this respected resource is bigger and better than ever. This latest Shooter’s Bible boasts 608 pages with hundreds of color photos and more than 1000 black-and-white photos. The new 107th Edition features many new firearms as well as new optics.
Published annually for more than eighty years, the Shooter’s Bible is perhaps the most comprehensive reference guide for firearms and their specifications. The publishers claim that “nearly every firearms manufacturer in the world” is included. The 107th edition also contains new sections on ammunition, optics, and accessories, plus up-to-date handgun and rifle ballistic tables. There are also extensive charts of currently available hunting and match bullets for hand-loaders.
While many shooters are now using the internet to get reloading data and equipment specifications, the Shooter’s Bible remains a valuable resource with a great legacy. As one recent Shooter’s Bible purchaser explains: “While it’s true that much of the information contained in the Shooter’s Bible can be found on the Internet, there are many of us who would first rather relax in our easy chair and page through the book at our leisure. If you find an item that catches your fancy, you can then follow up by going to their Web site.”
Another buyer observed: “This latest edition is proof that, even with all the attacks on our 2nd Amendment right over the years, the industry has persevered and grown. I hope the day never comes when there will no longer be a reason to publish the Shooter’s Bible.”
With a conventional barrel installation, employing a shoulder with a threaded tenon, it is difficult to index the barrel. Even with a cone breech (photo right) that eliminates the problem of extractor cuts, you’d have to use shims to alter the barrel index position, or otherwise re-set the shoulder each time you screwed the barrel in further.
