Just returned from South Dakota annual prarie dog shoot. Killed one at 1175yds. Stepped off and confirmed distance with Sierra Infinity program and with tech at Sierra. Rifle was Mauser action with Shilen 1:10 twist 243 bbl. Load was 95gr Sierra Match King behind 40.5gr of H4350 at 3040fps. This has been a very accurate load at 300yds but have not tried at long range until now.
