HORNADY A270 270 WIN LOCK-N-LOAD MODIFIED CASE

The Hornady Lock-N-Load Modified Case 270 Winchester (A270) is a brass tool case for reloaders who use Hornady Lock-N-Load O.A.L. and Precision Gauges to set exact bullet seating depth in 270 Win rifles. This A270 modified case for 270 Winchester works with Lock-N-Load gauges so you can match cartridge overall length to your rifle’s chamber instead of relying only on manual data.

Special Features
