Too many folks get hung up on drop figures and light fast bullets. They think it makes a 300 yard shot simple. Yet the wind drift issue is a huge factor, one indicating you need to lean towards a heavier bullet if you actually want to make longer shots.

In my 223 I shoot tons of ammo and usually use 69-90 grain bullets out to 1000 yards. Yet I use a 60 grain bullet a lot for practice. While any of the above work out to 200 yards, once you get to 300 yards the 60 grain becomes very tricky in the wind.
Just an example.
