TFB Review: New ISOtunes Sport CALIBER Wireless Bluetooth Earbuds

It’s universally agreed these days that eye and ear protection should always be worn when you’re out shooting. Whether you’re out hunting, competing at a match, or just out goofing around on the range, keeping your sensitive organs protected from unnecessary trauma is important if you want to keep listening to “ A Thousand Miles” by Vanessa Carlton on your way home from the range (don’t lie we all know you do it). Wireless earbuds have become extremely popular these days but often suffer from a couple of core drawbacks. A lot of wireless earbuds lack sufficient battery capacity to last you all day and others aren’t all that durable when it comes to hard range use. The new ISOtunes Sport CALIBER wireless Bluetooth earbuds aim to correct a few of those drawbacks and provide shooters with another option for convenient hearing protection both on and off the range. ISOtunes was generous enough to provide me with early access to these new earbuds for testing and evaluation and today we’ll take a look at the features, pros, and cons of these new earbuds to see if they’d be a right fit for you and the type of shooting that you do.

Hornady Announces a New Contender in the Caliber Wars: 6mm ARC

Hornady Manufacturing, widely regarded as one of the top ammo companies in the industry, has made quite a splash with their June 3, 2020 announcement. TFB recently hinted at a new SAAMI accepted cartridge, and now it’s here. Meet Hornady’s newest player: the 6mm ARC, or Advanced Rifle Cartridge. Purpose-built to optimize the capabilities of AR-platform firearms, the basic idea behind this new caliber is an attempt to find the sweet spot between the smaller traditional 5.56 NATO/.223 Rem, which is sometimes criticized for being perhaps a bit anemic, and larger calibers like .308 Win, which can raise issues such as increased weight and felt recoil with decreased mag capacity. With the 6ARC, Hornady believes they have landed on that happy medium – claiming that it “does what much larger cartridges can and everything that smaller cartridges can’t”, and “delivers optimum all-range performance and barrel life”. Hornady’s official press release reads as follows.

[SHOT 2018] Cadex's Sheep Dog Rifle and Innovative M2 MG Mount

Miles starts by examining the Cadex M2 Cradle Mount, designed for the Browning M2. On inspection of the mount we see the zero gravity capability and the ease of use provided for manipulating the Browning M2. On top of the Browning we notice the Cadex Kolos mount integrating a recoil mitigation system and a powered ballistic reticle optic. As Miles moves to the Sheep Dog Rifle, Rob Furlong discusses the calibers offered in the new actions as well as the new chassis offered for 2018.

[SHOT 2018] Federal's .224 Valkyrie Hits the Ground Running – 4 Years in the Making

What did we see at Range Day? Valkyries, Valkyries everywhere. Federal’s pint-sized long distance runner has already outstripped the market purchase of its direct competitors in the high performance AR-15 market, testified to by the sheer number of .224 Valkyrie rifles peppered across the booths and stalls of Range Day ’18.

.224 VALKYRIE Barrels Released by JP Enterprises

Those eagerly awaiting the market for the new .224 Valkyrie round have something to celebrate. Gunmaker JP Enterprises recently announced that they are now offering three different barrels for the new cartridge, in 20″ light, 20″ medium, and 22″ medium contours. All three barrels use the somewhat unusual “extra long” gas system, which is two inches longer than the standard “rifle length” gas system normally used with 20″ barrels. The longer gas system coupled with large diameter port settings reportedly increase dwell time while reducing the port pressure. More details on the barrels are available via a review from Recoil.

The Home Team Advantage: Ammunition, Compatibility, and Why Change Is Bad

If we can make a round that is significantly better than the existing 5.56mm or 7.62mm ammunition, shouldn’t the military just bite the bullet and switch, to the benefit of the servicemen and women in harm’s way? What’s stopping the powers that be from making the incremental improvements that everyone knows are possible?

9x39mm: AR-15 for Moose? [Modern Intermediate Calibers 026.2]

Previously, we compared the Russian 9x39mm subsonic sniper round to its Western counterparts, including the .300 AAC Blackout and the .45 ACP. As it stands now, the 9x39mm is a subsonic round only – no supersonic loads exist for it currently. But… What if they did?

.300 Blackout vs. 9x39mm: Russia's Subsonic Brute [Modern Intermediate Calibers 026.1]

Today’s Modern Intermediate Calibers will handle something a little different. While virtually all rounds we have looked at so far were designed primarily for supersonic use, today we will be taking a gander at the Russian 9x39mm round – a dedicated suppressed caliber designed exclusively for the subsonic flight regime, with no supersonic option (yet) available. This begets a question, then: Is the 9x39mm truly an intermediate caliber? To answer this, we should consider a few facts about the 9×39: First, it was designed for carbines and rifles with cartridge overall lengths comparable to common intermediate calibers, like 5.56mm or 7.62×39. Second, it was designed to give substantially better performance than is possible with pistol rounds, including armor piercing effect above that which is normally possible with handgun rounds. Third, it is used more like an intermediate caliber than a pistol caliber, being issued with a whole host of sniper rifles, assault rifles, and other weapons comparable to any other intermediate caliber. Therefore, I would argue that it is an intermediate, albeit possibly the strangest one in common use.

.224 Valkyrie Will Get a 100gr Bullet – Federal Premium Releases Official Data and Loads

Ammunition maker Federal Premium recently released its full bundle of press info on their new .224 Valkyrie round, coming on the heels of teasers released at Big 3 East. The .224 Valkyrie is a high performance .22 caliber round for the AR-15, which uses heavy, low drag bullets to dramatically improve the long range performance of the platform versus the .223 Remington and other rounds. This is the same principle that has been used in rounds like the .260 Remington and 6.5 Grendel for years, now finally applied to a factory .22 caliber round.

Are Long Range Infantry Calibers Just Marketing Smoke and Mirrors?

With the recent push for small arms ammunition with increased range, power and capability, are military customers in danger of being taken for a ride by industry marketeers working to sell rifles in new calibers? Is the primary driving force behind new infantry calibers not in fact a need to be addressed, but a desire to sell weapons in a stagnant small arms market?

BREAKING: Hearing Protection Act Moves Up, Hope for Saigas, Veprs, and 7N6, and No More Armor Piercing Bans? – H.R. 3668 SHARE Act

The effort to deregulate of silencers has reached an important milestone: The Hearing Protection Act has made it out of committee, and been incorporated as part of another larger bill. House Resolution 3668 – the Sportsmen Heritage and Recreational Enhancement (SHARE) Act – has been introduced to the House floor with a new subsection, Title XV, Hearing Protection. The new subsection provides for the change in classification of silencers from NFA items to standard firearms such as long guns, just like the HPA. Its text is reproduced at the bottom of this post.

Preference-Driven vs. Process-Driven Design in the Field of Small Arms Ammunition: Discussion

In yesterday’s article, we took a look at examples of two different methods of design, which I called “preference-driven” and “process-driven”. For these examples, I supposed two engineers from two different cultures – called “Romulan” and “Vulcan” after the aliens from the Star Trek universe.* In the “Romulan” example, we explored preference-driven design, where a final product is outlined by amalgamating preferred characteristics from previous works to create a desired whole. For the “Vulcan” example, we examined the more elaborate method of developing processes that can be fed data to procedurally generate characteristics as an example of process-driven design.
