Speer 155 Grain Hollow Point Ammo Details

These lightweight .40 Smith & Wesson rounds are a shining example of Speer's innovative approach to ammunition which enhances performance in every aspect. Each cartridge is ignited by a clean-sparking Boxer primer which leaves behind no corrosive salts or mercury. The primer and the reloadable brass casing to which it is attached are both nickel-plated to resist moisture in storage as well as to lower friction; this makes feeding and ejection much more smooth and reliable. The case is filled with a low-flash propellant which helps shooters regain a faster sight picture. Speer tops off this particular load with a 155-grain Gold Dot hollow point (GDHP) projectile.

While the weight is light for the caliber, it is common enough to match many .40 S&W practice loads while boasting relatively manageable recoil along with a flat trajectory of flight. GDHPs possess deep cavities at their noses which are encircled with precise core layering at the edges of their wide mouths. As a result, the bullets expand reliably while entering a threat which helps to create a larger wound tract, decrease the chance of errant over-penetration, and stop the bullet in vital areas for optimum energy transfer that will help drop a threat more quickly. The bonded jacket, which is applied via an electrochemical process, will never separate from the lead core and preserves fight-stopping momentum while helping the bullet defeat light barriers and thick clothing.
