Buffalo Bore 37B20 Heavy Strictly Business .327 FM 130 gr HC

The Buffalo Bore 37B20 Heavy Strictly Business load is a full‑power .327 Federal Magnum cartridge built around a 130 grain hard‑cast bullet. These rounds use a flash‑suppressed powder to reduce visible muzzle flash in low‑light conditions. They are formulated to deliver higher energy while remaining safe to fire in all‑steel revolvers and standard pistols. Buffalo Bore advises caution with very light alloy revolvers due to potential crimp jump under heavy recoil.
