Where to Draw the Line? Managing the Weight of Next Generation Universal Calibers Using a Weight Calculator

How can one balance the trade-offs inherent in ammunition design to create a true one-caliber infantry weapon system that is both effective and lightweight? This is a question I’ve been exploring for close to a decade, and writing about for over four years. The [Read More…]

Magpul D60 Sixty Round .223 Drum Overview and Mag Dump


In this episode of TFBTV, James tests out Magpul’s new D60 drum on the FN M4 rifle.  Magpul launched this drum after much fanfare and promises utter reliability and great usability. James puts these claims to the test as he runs through the function of the D60, along with a 60rd drum dump to [Read More…]

Future Firearms Ammunition Technology 008: Plastic-Cased, Telescoped Ammunition – Lightening the Load, Pt. 4

Previously, we discussed different concepts for lightening the soldier’s load, including aluminum-, composite-cased and caseless ammunition. Today we’re going to look at the weight-reducing concept that many believe is the horse to bet on when it comes to [Read More…]

14102915_10202159591549248_4055863750938407531_o Creedmoor .38 Ammo .264 USA The long-necked Colt 7.62mm round on the left combines the principles of triplex and squeezebore rounds (together called "salvo-squeezebore"). When fired from a modified M60 with a tapered muzzle, it would spit out three 55gr .224" caliber projectiles per shot. In the center is the duplex (not squeezebore) M198 7.62mm round, and on the right is the M80A1 EPR round, for comparison.

Future Firearms Ammunition Technology 007: Squeezebore Ammunition – Celeritas Et Accuratio

Previously, we discussed the benefits of and challenges facing saboted projectile ammunition, including the advantages of decoupling the diameters of the bore and the projectile, and the problems of accuracy during sabot discarding. One concept that could possibly [Read More…]

Future Firearms Ammunition Technology 003: Sabots – Performance-Enhancing Shoes for Your Bullets

One of the problems of small arms ammunition is that of swept volume. That is, the most ballistically efficient projectiles are the longest and thinnest ones, which cut through the air more easily than squatter, fatter projectiles. Yet, the best projectiles from a [Read More…]

So far, the polymer composite case has only found purchase with low-power specialty ammunition, such as the plastic blank and fired 7.62mm UTM marking round, both on the right. Several commercial composite cased rounds have been tried, including the grey .223 Remington PCA ammunition. In the 1970s, Frankford Arsenal and AAI experimented with composite cased ammunition, represented by the white cased round in the middle. On the left is a standard Korean-made M855 round.
