Rem Htp Cpr 357mag 140gr Xpb 20/200

Remington High Terminal Performance Copper 357 Magnum 140 Grain Barnes XPB ammunition delivers barrier-blind, controlled-expansion performance designed for duty and defensive carry. Each 20-round box contains factory-loaded rounds built around the monolithic copper Barnes XPB bullet—a proven projectile engineered to maintain weight and velocity through intermediate barriers while expanding reliably at service distances.

The 140-grain bullet weight in 357 Magnum represents a deliberate balance between velocity and controlled penetration. Loaded to standard pressure, this round achieves the velocity threshold needed for consistent expansion from the XPB's hollow-point geometry while staying within duty-rated ballistic performance windows. The Barnes XPB's solid construction resists fragmentation and deformation from drywall, auto glass, and intermediate materials—critical considerations for scenarios where over-penetration or barrier deflection can compromise shot placement.

This ammunition suits law enforcement duty carry, civilian defensive use, and field applications where barrier-blind expansion matters. The 357 Magnum platform delivers higher velocity than 9mm from comparable barrel lengths, and the 140-grain XPB load is lighter than many duty-oriented 357 alternatives, reducing felt recoil without sacrificing terminal performance. Operators and defensive shooters who have adopted Barnes XPB technology across multiple calibers recognize this formulation as a natural extension of proven performance principles.

Remington High Terminal Performance offerings occupy a distinct category within duty and self-defense ammunition—engineered to perform through realistic barriers and designed for repeatable terminal results. The XPB's monolithic construction and this 357 Magnum specification provide confidence-building performance for professionals and serious users who demand ammunition that performs as specified.
