I use a .243 for long range shoots around my area and can't think of a shoot that I had a disadvantage compared to the other shooters. The two competions are out to 1165yds. I have a 28" barrel 1-8" twist and shoot 105 hybrids at 3160ft/sec. with a 100yd zero it takes 9.5 MOA for 600yds and for 1000yds it is 23 MOA and 3.3 MOA of windage for a 5mph wind.
