WC MN | With 100 yard zero my drop is as follows with the 243 WSSM and 87 grain vmax at 3400 fps (that's a pretty stout load).
100 0.0
200 -1.9"
300 -7.9"
400 -18.6"
However, I keep a 200 yard zero to simplify things on "mils". 100 no compensation, 200 no compensation, 300 is ".5 mil" 400 is "1 mil"
100 +1.0"
200 0.0
300 -5.0"
400 -14.7"

I shoot F-class to 600 with the .243 wssm. My best score at 600 is a 189 4x. The 10 ring is 6" diameter and the x ring is 3". This is a factory win70 coyote special that's been trued, bedded and recrowned by myself. I put a trigger in it as well.
I cannot speak for ballistics for the "regular 243". I will say you will probably want the tight twist as I specified earlier if you are going any distance with them. Otherwise you are just getting pushed around in the wind with the lighter bullet choices available for the slow twists. When I rebarrel my 243 wssm, it's going to a 1:8. Coyotes don't care if they get hit with 105 grain bullet or 87 grain. It puts them down just the same but a miss is a miss so you gotta hit it first. I hardly worry about drop or velocity and instead worry about accurate ranging and compensation.
