Ultimate Ammunition Blue Line 9mm 90 grain solid copper hollow point 4023 ammo pairs a lightweight defensive projectile with a +P pressure designation. The 90-grain weight separates this cartridge from familiar 115- and 124-grain 9mm options, while the factory rates it at 1,540 fps. Together, those specifications identify a distinct Blue Line loading rather than a conventional-weight practice round.
In a monolithic hollow point, the nose and main bullet body are the same material, so there is no separate jacket to peel away from a lead core. That construction does not, by itself, establish how far the projectile will penetrate or how widely it will expand. A lighter bullet also does not independently determine felt recoil; the complete loading and the handgun affect what the shooter experiences with this ammunition.
The +P marking is especially important for anyone considering this cartridge for a compact pistol, since the firearm must be approved for higher-pressure 9mm loads. Product 4023 is supplied in a 20-round package with nickel cases. Shooters comparing specialized copper-bullet ammo can use the exact product number to distinguish this configuration from other lightweight defensive offerings.
