Here’s a sneak preview of the new March FX 5-40x56mm tactical scope from Kelbly.com. This FFP scope features a 34mm main tube, side focus adjustment (10 yards to infinity), and 24 milrads elevation travel (about 94 inches at 100m), with 0.05-milrad click values. The March FX will be offered in both a non-illuminated basic version (weight: 860gm or 30.3 oz.), and a higher-priced illuminated version (weight: 890gm or 31.4 oz.), with four brightness levels. So how much will these babies cost? MSRP for new March FX has not yet been announced, but we expect to get pricing info at SHOT Show in January.
First Focal Plane Reticle and Huge Magnification Range
Yes the FX features a First Focal Plane (FFP) milrad-type Reticle. This means that the ranging stadia (hash marks) remain constant relative to the target at all magnifications. So, you can range your targets using the milrad system at any power settings. That’s a big deal for tactical shooters. This new FX scope also offers an 8 times power range — the highest magnification ratio in any FFP rifle scope made to date. Is that valuable? Our tactical shooting buddies say yes.
On some tactical courses of fire, you can definitely use the full 40X magnification on precision targets at 800-1000m. However, for target spotting and close-range multiple target courses of fire, the 5X magnification, with its wide field of view, definitely comes in handy. AccurateShooter.com’s “Master Fabricator” Mark LaFevers currently uses a 12-42X Nightforce NXS in tactical matches. He likes the Nightforce but he tells us that: “The NXS I’m using with its minimum 12X does not open up enough for some of the close, multiple-target stations.” Overall, Mark was very intrigued by the new March FX: “I like the March’s 34mm tube and first focal plane design which allows ranging at all magnifications. Depending on the price, this scope would be a contender for the kinds of unknown distance, tactical competitions I’ve been doing. For benchrest, on the other hand, you really need a more finely-graded MOA-based adjustment system, in my opinion.”

21st Century Shooting’s all-new Concentricity Gauge looks like a winner. The cartridge case rides on four spinning rollers that allow smooth turning movement with low drag. These rollers are far superior to a set of V-Block supports, or even some ball-type supports.
The amount of eccentricity (run-out) is measured with a high-quality horizontal dial test indicator. In this application, a horizontal indicator works better than the typical vertical dial indicator with spring-loaded shaft used in most other concentricity gauges. We think that, with 21st Century’s new Concentricity Gauge, you can measure cases faster, with less effort, and greater repeatability. In addition, this device can measure the INSIDE of the case neck, not just the OUTSIDE.
Overall, this is a very impressive new tool that is unquestionably superior to many other Concentricity Gauges on the market. Given the capabilities of this device, the price is reasonable: $169.00 including Horizontal Indicator. The Gauge by itself costs $125.00, while the Indicator alone sells for $59.00.

Why the New 21st Century Concentricity Gauge Works So Well
21st Century explains the advantages of its new design: “At 21st Century Shooting, our goal to modernize an industry that has seen little change over the years. The new concentricity gauge is a perfect example. Most conventional concentricity gauges use what is called a height indicator gauge (Dial Indicator with vertical shaft). Although economical, this type of gauge was not intended for the purpose of measuring rotating diameters. The vertical-style indicator can produce inaccuracies due to indicator rod flex and bounce.
Our new Concentricity Gauge uses a horizontal dial test indicator. This type of gauge was designed specifically for checking rotating diameters and in fact is exactly the type of gauge used in the machining industry for decades to measure run out — the very thing that we as hand loaders are striving to minimize or eliminate.
Additionally, our new gauge uses Stainless Steel turning rollers as opposed to fixed bearings or V-block style case supports. You will especially appreciate the roller supports that glide on linear guide-ways. Plus, with a simple push of a button you can adjust the case support base width. No tools are needed to move the base on the built-in guide-ways.”

Following up on the success of its Zombie-Max ammunition, Hornady has introduced a new line of Z-Max Varmint Bullets fitted with “slime green”-colored plastic tips. What can we say — it’s a gimmick but it sells. P.T. Barnum would be proud. Hornady will initially offer seven (7) types of Z-Max bullets, in calibers .172 through 7.62 (.310), with weights from 20 grains to 123 grains.
Alexander Arms is now shipping production 17 HMR AR15 rifles and 17 HMR upper receiver kits. The complete rifles are the only semi-auto rifles specifically designed to reliably shoot the 17 HMR cartridge. Alexander Arm’s 17 HMR rifle does not employ a reworked .22LR rimfire action. Instead the gun features a new bolt assembly design purpose-built built to work with the 17 HMR cartridge. This is good news for varmint hunters who want semi-auto capability for fast follow-up shots in the varmint fields.
The complete rifle comes standard with a straight fluted 18″ stainless barrel, A1 flash-hider, free-floating composite hand guard and two molded-plastic 10-round magazines. Options include a spiral-fluted barrel and MK3 railed upper receiver. Alexander Arms’ 17 HMR ARs will be offered in both fixed stock and collapsible-stock versions. The upper receiver kit includes all the ancillary items needed to convert existing AR15 lowers to work with the 17 HMR cartridge.
17 HMR Basics
If you are not familiar with the 17 HMR, it is a popular varmint cartridge effective out to 200 yards or so. With typical muzzle velocities of 2550-2650 fps, the little 17 HMR packs much more punch than a .22LR, while bucking the wind much better. CLICK HERE for Varmint Al’s 17 HMR webpage, which provides a comprehensive analysis of 17 HMR ballistics, kinetic enegy, and effectiveness on small varmints.

On its website, Alexander Arms reports: “Our initial production run will be 500 units. We are extremely pleased with this [17 HMR] caliber. With help from Hornady, this unit has been extensively tested and has proven itself to be very capable in the field. At the recent Big 3 Event, we ran two rifles out to ranges of 400 yards and despite windy conditions… the guns performed well. While running guns at the Big 3 we had an opportunity to run one of the rifles with the excellent magnum rimfire silencer from Thunderbeast Arms Corp. The rifle exhibited a slight shift in zero and ran without a hitch for the two days of the event. This unscheduled test provided a quick insight into the flexibility of the rifle and everyone agreed that this combination would serve well for any varminting purposes.”
An Italian company, CompBullet, has produced a radical new line of CNC-machined projectiles with a cavity in the bullet base connected to ports (holes) placed radially around the bullet’s circumference. Currently CompBullet offers six bullet types: 9mm (100 gr), .40 cal (155 gr), .44 Cal (200 gr), .45 Cal (200 gr), and .30 Caliber Rifle (125 gr). CompBullet’s pistol projectiles have one row of radial ports, while the longer rifle bullets have two rows, resembling the porting on a muzzle brake.
Italy’s CompBullet makes many claims about its new, patented ported bullets. Supposedly the ported, cavity-base bullets go faster than conventional bullets, yet generate less recoil. CompBullet also claims that its radical projectiles produce less smoke and reduced flash on exiting the muzzle. We are skeptical of many of CompBullet’s claims. We also have some concerns about bullet integrity and potential safety issues — at least when used in high-velocity applications.
Velocity
Compbullet claims that gases exiting the radial ports “lubricate” the bullet as it travels down the bore, yielding enhanced velocity. However, if any gas is actually able to exit the holes while the bullet is in the rifling (it’s not clear that in-barrel venting really occurs), then this will simply serve to REDUCE the gas pressure pushing on the base of the bullet. If anything, the bullet should go slower than a conventional projectile, not faster.
Jet Effect
CompBullet projectiles have a cylindrical cavity in the base. CompBullet claims that hot gases will shoot out the bottom of the bullet (like a rocket) and this increases velocity. But this runs contrary to the bullet-maker’s claim that the hot combustion gas moves forward and out the vents. But what, you might ask, if there are powder kernels that have migrated into the cavity and ignite inside the bullet? That might indeed cause gas to move both forward and rearward. However, the force of any rearward gas jet would be minimal compared to the main pressure flow pushing from behind, at least while the bullet is in the barrel.
Reader’s Comment: Hope the holes are small enough so the powder doesn’t fall out if the round is tipped over or something. It’s a good idea for custom salt and pepper shakers though!” –Josh
Recoil Reduction
Muzzle brakes reduce felt recoil and muzzle lift, on both pistols and rifles. However, they are attached to the gun. We’re not sure how gas blowing out the sides of a bullet is going to have any effect on recoil, because that action occurs after the bullet has left the muzzle. It IS possible that some in-barrel venting from the bullet’s ports may occur (if the ports aren’t blocked by the rifling), but that, as explained above, will only serve to reduce pressure pushing on the base of the bullet and hence reduce velocity. To the extent CompBullet projectiles deliver less felt recoil (if they do), it’s probably because they have lower velocity. If CompBullet projectiles actually fly faster (than do conventional bullets), that would be easy to demonstrate with chronograph tests. However, CompBullet provides NO CHRONOGRAPH DATA on its website. Without such data, we remain unconvinced.
Safety Issues
With a CompBullet projectile, there is the potential for powder to shift from the cartridge case into the bullet’s central cavity, prior to ignition. If this occurs, and the kernels inside the bullet do not fire off prior to the bullet leaving the barrel, there is the possibility of an explosive fragmentation of the bullet once it leaves the muzzle. We don’t know if this could actually happen, but there’s a word for a small, metal container filled with gunpowder — a grenade.
Bullet Integrity
A conventional jacketed bullet can fly apart when the combination of heat, friction, and spinning force stresses the bullet’s construction. With the CompBullet projectile, you have a bullet that is heated from the inside out, with numerous weakening holes drilled in the structure.
Accuracy
We discussed the effect of radial ports on a bullet with Bryan Litz, chief Ballistician for Berger Bullets. He said: “this ported bullet design is interesting, but I can’t see how it would have any usefulness for precision shooting. If flaming gas really jets out the ports, and the outflow of every port is not perfectly uniform, then this will quickly cause a reduction of bullet stability, which won’t help accuracy at all.” Bryan also wondered if drag from the gas out-flowing from the ports might slow down bullet spin-rate. With less rpm, spin-stabilization would be reduced. “Unstable bullets are not accurate”, Bryan added.
Flash Signature
There does appear to be some evidence of a smaller smoke “cloud” on bullet exit and a reduced flash signature, if the photos on the CompBullet website can be believed. We would like to see an actual comparison between conventional ammo and CompBullet ammo, using identical powder charges. CompBullet’s photos do not provide a comparison with ammo loaded with non-ported bullets. We cannot confirm that flash is reduced unless we can see photos of both ported and non-ported bullets, shot with the same powder loads, in the same lighting conditions. See sequence below with 9x21mm pistols:
The inventor of the CompBullet ported projectile is Alain Della Savia, a IPSC Grand Master and 6-time Italian National Revolver Champion. He was inspired by the recoil reduction offered by ported handguns. He hoped to develop a new kind of ammo that had reduced recoil, while still satisfying the IPSC “power factor” requirements. His solution was to build ports in the bullets themselves, using CNC-machining methods: “After a year of experiences, [Alain] found the right balance between materials and internal compensation system inside the bullet.”

Colt’s Manufacturing Company LLC (“Colt”) announced that it will open a new firearms production facility in Kissimmee, Florida. Colt’s announcement did not discuss plant closures elsewhere, but we expect that some of Colt’s production (and jobs) will be moved from New England to Florida. Colt’s press release states: “The new 16,000-square foot facility will allow Colt’s Manufacturing Company to expand into new markets and business lines in parallel with the company’s existing 100,000-square-foot facility in Connecticut. Specific information on facility renovations and employee requirements will be determined over the course of the next several months.”
Colt Introduces New California-Compliant ARs
In related news, Colt has introduced a series of California-compliant AR15s. This is good for “black rifle” fans in the Golden State. Colt’s CA-legal ARs include: a 16″ barrel M4 Clone (LE6920CA) with adjustable stock; an Accurized rifle with 24″, 1:8″ twist heavy barrel (CR6724CA), and a “Patrol Rifle” that features Magpul furniture (6920CMP-B). All of Colt’s new California-compliant rifles are test-fired at the factory, and they all have mil-spec barrel, chamber, and bolt carrier group. In addition, Colt’s ARs receive special metal testing. Steve Comus, who reviewed Colt’s new ARs for Western Outdoor News, explains: “There is a magnetic particle inspection test done on all Colt rifles. After a rifle passes the MP (Magnetic Particle) test, MP is stamped on the bolt and barrel, as is C for Colt and MP on barrel. To pass, every single barrel and bolt goes through an over pressure test of 70,000 psi to make sure it can handle high pressure. Colt then takes rifle barrel and bolt and does a magnetic particle test on them. Barrels on mil spec barrels are chrome-lined. Accurized barrels are not chrome-lined.”
Here’s a fun gift item from Vat19.com — a bottle opener made from de-milled .50 BMG cartridges. These .50 Caliber Bottle Openers are made by hand in the USA by a group that donates at least 15% of its profits to helping wounded soldiers via the Travis Manion Foundation.
The price is $14.99. Considering the simple design, we bet many of our readers could make their own bottle opener using an old cartridge, a Dremel tool, and a file. If that’s too much work, you can order the .50 Cal bottle opener from Vat19.com. This item has been so popular that it is currently sold out, but Vat19.com is expecting to receive more inventory on December 19th — right before Christmas.
Here’s a clever product that provides visual feedback of your aim on the target while you dry-fire. LaserLyte, makers of laser pistol sights and bore-sighting tools, has come up with a smart new application of a miniature laser system. The new caliber-specific Laser Trainer Cartridge fits inside the pistol chamber and features a firing-pin activated switch that indicates bullet impact with a bright red laser dot. To practice, simply cock the hammer or striker, and pull the trigger as you would normally. When the firing pin hits the Laser Trainer Cartridge, a bright red laser displays on your target for 100 milliseconds. Available for 9mm, .40 S&W, and .45 ACP, the $99.95 (MSRP) Laser Training Cartridges are rimless so you can work the slide without ejecting the Laser Cartridges.
With a Laser Trainer Cartridge in the chamber of your 9mm, .40 S&W, or .45 ACP pistol, you can practice your trigger pull and sight acquisition. But unlike traditional dry-firing, you can see your point of aim when you “break the shot”. This modified cartridge is rimless, so the Laser Trainer Cartridge is not expelled during dry fire, which allows for tap, rack, bang or malfunction training drills. A hardened rubber plunger on the laser also acts as a built-in snap cap to protect the firing pin. The Laser Trainer Cartridge requires three #377 batteries, good for approximately 3,000 shots. For more info on Laser Training Cartridges visit LaserLyte.com.
Legendary pistol and 3-Gun shooter Jerry Miculek stars in a great instructional DVD set from Brownell’s.
