range session 270Win with 140SST Superformance ammo

Recommended Posts

Friday got in a 90 minute shooting session at the BA Frank DeSomma range. Calm morning about 70 and cross wind component of 3-4 mph. I was verifying my custom 270 at 218, 328, 420 and 547 yards. I was using a custom built on an older REM 700 action with a #4 24 inch Lilja barrel and Hornady 140SST Superformance ammo. This build has been very accurate with the Hornady ammo  that has been sorted for bullet runout of .001-.002. I wanted temperature near what my NOV hunt would be and calm winds to get base performance, this has been a pre hunt routine for several years.  Using StreLok Pro ballistic app with my input of temp, humidity and station pressure I came up with my dialup. All targets were 2MOA. This ammo runs at 3160 fps at the muzzle. Red steel 328y - Blue steel 420y and Green 547y.
