HORNADY B270 270 WBY MAG LOCK-N-LOAD MOD CASE

The Hornady Lock-N-Load Modified Case 270 Weatherby Magnum (B270) is a brass tool case for precision reloaders who use Hornady Lock-N-Load Precision and O.A.L. Gauges to set exact bullet seating depth in 270 Wby Mag rifles.

• Hornady prepares B Series modified cases like the B270 specifically for the Precision Gauge system, giving you a chamber-realistic baseline instead of a generic test body.
