1. Amazon — Caldwell Long Range Target Camera System, $367.70
Forum members have purchased this Caldwell Target Cam System and they’ve found that it works reliably, providing a clear signal to any WiFi-enabled mobile device (smartphone, iPad, Laptop). One member specifically tested the unit at 1000 yards and it functioned fine. NOTE: This system does NOT have a zoom camera lens, so you need to position the camera within 10 yards or so of the target. But if you place it to the side a bit, this shouldn’t be a problem. This system comes with a nice, fitted carrying case that holds camera, transceivers, antennas, and stands. You get a very capable system for under $370.00 (Amazon price includes free shipping for Prime members). You can also get this system from Midsouth for $357.02 (shipping extra).

This is a totally new kind of hearing protection. Walker’s Razor-X and Razor-XV operate like electronic muffs — allowing you to hear commands and conversations while still blocking gunshots and other loud noises. The Razor-X combines a collar unit (containing the electronics) with retractable, foam-tipped ear buds. Unlike conventional earmuffs, the Razor-X system doesn’t interfere with your cheek weld. The patent-pending earbuds allow the user to be in loud environments without damaging their hearing, providing an impressive 31dB of noise reduction.
The kit includes two different styles of noise-reducing foam tips (in various sizes) to ensure a good fit for maximum noise reduction. The Razor-X is equipped with an auto-shut off after 4 to 6 hours. An AC wall adapter with USB port and a one-meter micro USB cord is provided.
TECH NOTE: Grafs.com shows a 29dB NRR in the product title. However, the manufacturer (and all other retailers) list a 31dB Noise Reduction Rating for the Razor-X and Razor-XV.
Here’s a super deal on a premium Tactical spotter package. Right now you can get a Leupold MK4 TMR 12-40x60mm spotting scope, PLUS a Delta-Point Pro 2.5 MOA Red-dot (for quick aiming), PLUS a Badger SLICK mount for under $1500.00. The Leupold MK4 12-40 spotter sells for $1399.00 by itself elsewhere. So this is like getting the Delta-Point and SLICK mount for $100.00 (or free — read about $1400 special below). CLICK HERE for Package Deal.
The unique SLICK mount is definitely worth having. This lets you add a laser rangefinder or other accessory and have the LRF aligned (collimated) perfectly with your spotting scope.
Jason tells us: “This is the best value I have seen on gear in a long time. On top of that, we are offering AccurateShooter.com readers a FURTHER discount to $1400 shipped for pre-ordering (pre-payment required)”.

Exclusive iSmart Technology… ensures fastest and most efficient charge.”
Need quality .22 LR rimfire ammo at an affordable price? Consider Norma. Most folks think Norma only produces centerfire ammo and cartridge brass. As a result, people haven’t been looking for Norma rimfire ammo. Their loss is your gain. Accurate, reliable Norma .22 LR ammunition is in-stock right now at leading online vendors. This is good quality ammo, made in Europe. Bullets.com has Norma Tac-22 ammo in stock at $5.25 per 50-rd box (SKU: BL7819). In addition, Bullets.com offers Norma Match-22 ammunition at $7.50 per 50-rd box (SKU: BL11887).
Everyone needs a good .22 LR rimfire handgun, and the Browning Buck Mark is a classic. This stainless, bull barrel version is marked down this week to $379.99. That’s a very good price. Buckmarks, with their excellent triggers and great ergonomics, are fun to shoot and VERY accurate. This is a pistol you can keep for a life-time and pass on to your kids. Browning says: “Every Buck Mark starts out as a solid piece of aircraft-grade 7075 aluminum alloy, and then is CNC machined to exacting tolerances. The crisp single-action trigger, hand reamed chamber, target crowned barrel and finely adjustable target sights mean the Buck Mark comes ready for fun straight from the box.”
6. Widener’s — Norma 203B and 204 Powders on Sale
Looking for an excellent powder for your .308 Win, 6BR, or other small-to-midsized cartridge? You should consider Norma 203B. This Bofors-made powder is essentially the same as Alliant Reloder 15, which has set many records in the 6mmBR and 6mm Dasher cases. Right now Norma 203B is on sale at Wideners.com for just $19.95 per pound. That’s a great deal for an outstanding propellant. Other vendors charge up to $29.00 per pound for Norma 203B.

7. Amazon — Kowa 60mm TSN-601 Spotting Scope Body
If you are looking for a rugged, reliable, and affordable spotting scope to watch flags, mirage, and shot spotting discs, this angled-body Kowa TSN-61 will do the job. These Kowa spotters have been used successfully for years by prone and High Power competitors. Sure the glass is not as sharp as the latest top-of-the-line HD spotting scopes, but the TSN-61 is a small fraction of the price of high-end models which can run $2000 or more. The money you save can buy four premium hand-lapped barrels. NOTE: This item is the scope body only. Eyepieces are sold separately — expect to pay $260.00 – $300.00 for a Kowa 20-60X Zoom eyepiece.
8. Harbor Freight — Ammo Box and LED Light Super Savings
Here are two great deals from Harbor Freight — both coupons are good through the end of March, 2016.

Story Tip by Boyd Allen. We welcome reader submissions.
Take a good look at this unusual ammunition. We think you are looking at the future of handgun ammo — at least for range and practice work. This patent-pending ammunition features a 100% lead-free bullet blended from polymer (plastic) and copper powder. The polymer-copper matrix (PCM) composition offers three major benefits: 1. the bullets do not ricochet; 2. the bullets are lighter and therefore faster than conventional projectiles; and 3. the bullets are environmentally friendly. We think this is a big deal — we predict matrix pistol bullets will become extremely popular in the years to come.
At the 2016 SHOT Show Media Day, we shot ammo with PCM bullets in a half-dozen handguns. The ammo performed flawlessly, without a hitch. In .40 SW and .45 ACP pistols, the felt recoil was considerably less than with conventional lead-core ammo (the difference was less noticeable with .380 ACP and 9mm Luger).
Ruger is now offering Ruger-branded ARX ammo with polymer-copper matrix bullets. This ammo will be produced under a licensing agreement with PolyCase Ammunition, the Georgia-based business that originally developed this bullet technology.
While Ruger is touting this ammo as a self-defense solution, we think the most common use of this new ammo will be for indoor practice, plinking, gun games such as IDPA, and use on steel and reactive targets. If you like to shoot steel, matrix bullets make sense. The polymer-copper matrix bullet basically disintegrates into very small fragments when it hits metal.
This video includes extensive tests of Ruger 9mm ARX ammo:
Ruger ARX Ammo with Injection-Molded Matrix Bullets
The fluted projectiles are injection-molded from a polymer-copper matrix. This offers many advantages. First, being completely 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 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, rather than ricochet. This makes them well-suited for indoor use, or use with metal plates.
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.
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.”
Polymer-Copper Matrix Bullets Show Good Penetration
Despite their lighter-than-average weight, ARX bullets show good penetration in ballistics gelatin, thanks to their unique, fluted-tip design. This video shows penetration tests:
Bryan Litz with his F-TR Nat’l Championship-winnning rifle, and the man who built it, John Pierce.
Bryan Litz knows something about bullet shapes and dimensions. He’s the chief designer of many of Berger’s projectiles, including the successful line of Hybrid bullets. Bryan also understands how bullets actually perform in “real world” competition. Bryan won BOTH the Mid-Range and Long-Range National F-TR Championships this year, a remarkable accomplishment. With Bryan’s technical expertise combined with his shooting skills, few people are better qualified to answer the question: “how should I sort bullets when loading for competition?”
Bullet Sorting Strategies — OAL vs. Base to Ogive
At the 2015 Berger Southwest Nationals, Forum member Erik Cortina cornered Bryan Litz of Applied Ballistics. Erik was curious about bullet sorting. Knowing that bullets can be sorted by many different criteria (e.g. weight, overall length, base to ogive length, actual bearing surface length etc.) Erik asked Bryan to specify the most important dimension to consider when sorting. Bryan recommended sorting by “Base to Ogive”. Litz noted that: “Sorting by overall length can be misleading because of the nature of the open-tip match bullet. You might get a bullet that measures longer because it has a jagged [tip], but that bullet might not fly any different. But measuring base to ogive might indicate that the bullet is formed differently — basically it’s a higher resolution measurement….”

How do you build better (more precise) ammo drop tables? With radar, that’s how. Barnes Bullets is using Doppler Radar to develop the drop tables for its new Precision Match line of factory ammunition. The Doppler radar allows Barnes to determine actual velocities at hundreds of points along a bullet’s flight path. This provides a more complete view of the ballistics “behavior” of the bullet, particularly at long range. Using Doppler radar, Barnes has learned that neither the G1 nor G7 BC models are perfect. Barnes essentially builds a custom drag curve for each bullet using Doppler radar findings.
Use of Doppler Radar to Generate Trajectory Solutions
by Barnes Bullets, LLC
Typical trajectory tables are generated by measuring only two values: muzzle velocity, and either time-of-flight to a downrange target, or a second downrange velocity. Depending on the test facility where this data is gathered, that downrange target or chronograph may only be 100 to 300 yards from the muzzle. These values are used to calculate the Ballistic Coefficient (BC value) of the bullet, and the BC value is then referenced to a standardized drag curve such as G1 or G7 to generate the trajectory table.
This approach works reasonably well for the distances encountered in most hunting and target shooting conditions, but breaks down rapidly for long range work. It’s really an archaic approach based on artillery firings conducted in the late 1800s and computational techniques developed before the advent of modern computers.
There is a better approach which has been utilized by modern militaries around the world for many years to generate very precise firing solutions. Due to the sizeable investment required, it has been slow to make its way into the commercial market. This modern approach is to use a Doppler radar system to gather thousands of data points as a bullet flies downrange. This radar data is used to generate a bullet specific drag curve, and then fed into a modern 6 Degree of Freedom (DOF) [ballistics software program] to generate precise firing solutions and greatly increase first-round hit probability. (The 6 DOF software accounts for x, y, and z position along with the bullet’s pitch, yaw, and roll rates.)
Barnes has invested heavily in this modern approach. Our Doppler radar system can track bullets out to 1500 meters, recording the velocity and time of flight of that bullet every few feet along the flight path. Consider the graph below showing a bullet specific drag curve referenced to the more common G1 and G7 curves:
Neither of the standard curves is a particularly good match to our test bullet. In the legacy approach to generating a downrange trajectory table, the BC value is in effect a multiplier or a fudge factor that’s used to shift the drag curve of the test bullet to try and approximate one of the standard curves. This leads to heated arguments as to which of the standardized drag curves is a better fit, or if multiple BC values should be used to better approximate the standard curve (e.g., use one BC value when the velocity is between Mach 1 and Mach 2, and a different BC value when the velocity is between Mach 2 and Mach 3.) Barnes’ approach to creating trajectory tables is to generate bullet-specific drag curves, and use that data directly in a modern, state-of-the-art, 6 DOF ballistics program called Prodas to generate the firing solution.
