Jurras’ new company, Super Vel Ammunition, put jacketed hollow point on center stage with police departments and federal agencies. By using a light bullet of 110 grains in .38 Special and .357 Magnum, Jurras could push the velocity over 1,400 fps with a huge increase in kinetic energy, nearly 500 ft/lbs, but at the same time his bullets expanded dramatically, increasing the frontal surface area of the bullet to cut a larger wound channel and to slow it and stop it from exiting. Jurras and his partner J.D. Jones tested his super-fast new bullets on everything from car doors to blocks of wet clay to stacks of newspaper and, yes, big game animals. The proof was overwhelming— the jacketed hollow point was far more effective at "stopping power" than conventional bullets...
... Super Vel also loaded subsonic 9mm Luger cartridges with a 158 gr. FMJ which was type-classified by the U.S. Navy as the Mk 144 Mod 0 9mm. It was for a special S&W pistol fielded by the Navy SEALs in Vietnam called the Mk 22 Mod 0 but better known as the Hush Puppy. The gun was a highly modified version of the Model 39 with a suppressor to take out Viet Cong guard dogs as the SEALs snuck behind enemy lines to rescue POWs and downed pilots— hence the name Hush Puppy. Today, we offer the very same subsonic load, a duplicated of the original SEAL subsonic load.
When Super Vel burst on the scene in 1963, virtually all policemen carried .38 Special service revolvers and the standard load was a 158 gr. lead roundnose trundling along at a lazy and sedate 850 fps. This load was absolutely terrible, with little kinetic energy to affect an instantaneous "stop" yet with a bullet profile that over-penetrated and went ricocheting all over the neighborhood. Jurras and his 110 gr. jacketed hollow point would solve this, and solve it in spades.
But Super Vel's problems were not limited to obtaining components. At the same time, Super Vel's potent 90 gr. JHP 9mm Luger load was drawing some concern for being "too hot" for the then-new Smith & Wesson Model 59, the first American-made double-stack 9mm pistol. The feedramp on the Model 59 was cut such that a good portion of the rear of the cartridge was unsupported by the chamber, and some case "blow outs" occured on the Model 59. Word that Super Vel was "too hot" spread. It was hard to explain that it wasn't the ammo, it was these new guns with their feedramps and unsupported chambers! Of course Super Vel's competitors were only too glad to pass along these stories of blown-up guns!
The result of this testing was the Super Vel Cartridge Company, founded in the mid-1960s. It offered 90-, 110- and 125-grain loads in .38 Spl. and .357 Mag., as well as light bullet loads in 9 mm, .45 ACP and other calibers. And, this new ammunition drove bullets at velocities that others only dreamed of. Bullet design and increased velocity gave a much better chance of acceptable expansion, while reducing penetration to a useful level. Super Vel was the ammo of choice when I went into police work. I was able to examine the results of several shootings where Super Vel was used and, in every case, the results were impressive. Sadly, the future for Super Vel was not all that rosy.
The lineup covered all the typical chamberings: .380, .38 Special and .357 Magnum, 9mm, .45 ACP and .44 Magnum. Some used normal-weight bullets, but the real performers were the .38/.357, the 9mm and the .45, all of which used bullets lighter than customary.
The .38 and .357 loads, for example, both employed 110-grain bullets. The speeds the company achieved were way beyond any other ammo being produced at the time by other makers. (Super Vel allegedly also manufactured slower ammo from a facility in Greensburg, Indiana.)
