Savage .308 rifle... Bushnell Trophy 3-9x40 scope... Accurately sighted to 150 yards dead on. No need to go any more than that, especially in the thick woods of Virginia. I am not steady enough (i.e. confident enough) to try to do some crazy 500 yard shot across a huge field. I have no idea what the trajectory would even be for a .308 at 500 yards!!!
Also, my longest shot, clean kill, DOA right there on the spot: 125 yards with my Savage .308 and a 165gr Ballistic Tip round, up on my sister & bro-in-law's farm in upstate NY back in 2011. Bang... Flop... DOA right there. One shot, one kill. Didn't get just a clean pass-thru in the chest - I actually blew the aorta right off the deer's heart! Deer had no idea what hit him and it was instant "lights out".
