RE: help me with my 243
Look up any of the ammo manufacture' s web sites and look at their ballistic charts.
I would highly suggest you shoot some at 100 and 200 yards, especially if you' re planning on shooting that far. Ballistic tables are good, but not as near accurate as you might think. Also, if you' re shooting at 50 yards, and say you' re off an inch left or right, you' re going to be off a bunch at 200 yards.
