U.S made Soviet VSS Vintorez suppressed rifle

The Vintorez is a suppressed rifle currently in use by a number of Russian Special Operations units. It was used extensively in the Chechen conflict, in addition to popping up in Syria as well. It fires a special 9x39mm SP5 cartridge in addition to an armored piercing [Read More…]

All of these rounds have different characteristics that affect their ballistic performance and their reliability in automatic firearms. We'll be taking a closer look at these characteristics to better understand the trade-offs in small arms ammunition design.

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…]

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…]

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 006: Multiplex Projectile Ammunition – Two, Three, Four for the Price of One?

After World War II, US Army analysts determined that the effectiveness of the infantryman was not as closely related to their marksmanship discipline as had been previously thought. It seemed that instead, the random environmental circumstances and effects, plus the [Read More…]

Future Firearms Ammunition Technology 005: Caseless Ammunition – Lightening the Load, Pt. 3

Previously, we discussed trying to lighten the soldier’s load by making the cartridge case out of different materials, including aluminum and compositing the case out of polymer and metal. Yet, wouldn’t the lightest possible case configuration be… [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.
