Item # 292462 Style BFF-25C/20 UPC 651815025032 Condition New Manufacturer [Buffalo Bore](https://www.kygunco.com/brand/buffalo-bore) Units Per Box 20 Caliber 357 SIG Weight 0.75 lb - **Purpose:** For those seeking a .357 SIG load with deep penetration and reliable expansion, this is the solution. - **Bullet Type:** Lead-free, all-copper Barnes TAC-XP bullet - **Performance:** Penetrates approximately 20+ inches in flesh and bone, while expanding to roughly .55 caliber - **Low-Light Advantage:** Uses flash-retarded powder to preserve shooter vision in low-light conditions. Approximately 95% of civilian shootings in the U.S. occur in low light, making this feature a tactical asset. - **Powder Capacity Consideration:** In compact casings like .40 S&W, 9mm, .380 Auto, and .357 SIG, long-for-weight copper bullets reduce available powder space, resulting in slightly lower velocities. Despite this, the benefits of Barnes copper bullets outweigh the limitations for most users. - **Velocity Testing:** Buffalo Bore uses real-world pistols to determine advertised velocities. This approach contrasts with the industry’s use of extra-long laboratory barrels that produce misleadingly high velocity figures not achievable in actual firearms. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
