Federal Premium Hydra-Shok Deep 45 ACP AUTO Ammo 210 Grain Hollow Point Projectile ammo review offers the following information; This 45 ACP cartridge from Federal’s Hydra-Shok Deep line of ammunition sports a 210 grain jacketed hollow point projectile. This exciting improvement on the classic Hydra-Shok bullet, which has been favored by self-defense experts since its introduction in 1989, has an even sturdier center post along with an improved core design which together cause it to penetrate to a depth of 15 inches in bare ballistic gel. That depth is considered ideal by current FBI test protocol, and is sufficient to devastate a human-sized target while mitigating risk to bystanders. This bullet’s jacket features cuts along its tip, which promote devastating expansion within soft targets. The round’s propellant is specially formulated to create the velocity best suited for its bullet’s technology to shine with, and its Federal primer provides extremely reliable ignition. Finally, its brass casing’s nickel plating facilitates feeding and ejection in semi-automatic weapons, as well as providing great resistance against corrosion. All in all, this cartridge is a superlative choice for anyone who’d rely on a 45 in a life or death situation.
