First Use Experience
I tested the Cor Bon 357 Mag 140 Grain JHP at an indoor shooting range, focusing on accuracy and felt recoil. I used a Smith & Wesson Model 686 and a Ruger GP100, both with 4-inch barrels, at distances of 7, 15, and 25 yards. The range conditions were controlled, with consistent lighting and temperature.
The ammunition performed remarkably well, with consistent groupings at all distances. Recoil was noticeable, as expected with a .357 Magnum round, but manageable. The rounds fed and ejected flawlessly in both revolvers, with no signs of malfunctions.
The initial surprise was the muzzle flash and report; these rounds are LOUD and produce a significant visual signature. This confirmed the high velocity claimed by Cor Bon. The accuracy was impressive, and the felt recoil was acceptable for a defensive cartridge.
Extended Use & Reliability
After several months of use, including multiple range sessions and carrying it as my primary self-defense load, the Cor Bon 357 Mag 140 Grain JHP has proven to be exceptionally reliable. I have fired approximately 200 rounds through my revolvers with zero failures. The ammunition continues to perform consistently, even after being stored in varying temperature and humidity conditions.
There is no significant wear and tear on the casings or bullets after storage and repeated handling. Cleaning my revolvers after using the Cor Bon ammunition is straightforward. Carbon fouling is minimal and easily removed with standard cleaning solvents.
In comparison to other self-defense rounds I have used, such as the Winchester Silvertip and Remington Golden Saber, the Cor Bon stands out for its consistent accuracy and powerful recoil. It inspires confidence knowing that I am carrying a round with a proven track record for stopping power.
