I out did myself yesterday evening and broke my previous record of 415yards. I dropped a deer yesterday @ 575 yards. Shot him with my 300 win. Mag Rem 700 Sendero and the 175gr. Sierra Match King. There are very few feelings in this world like hearing a hit! and seeing a deer buckle through your scope after the recoil of your rifle! Especially at that distance. It seems like slow motion or something. I am so excited!
