.243 is a good option, I'm picking one up for antelope and maybe deer.

For what you described one of the .308 versions is certainly the way to go I think. Though I think the 7mm-08 might be a better choice, more versatile than the .243 just in case, also under 200yds, youc ould shoot a heavier bullet, and while the .243 could do the job, on deer.....under 200 yds, I think the 7mm-08 would be better. and loading up to 160grs or so in the future say on a bear hunt or somethin gif that were to come would certrainly be better than a 100gr bullet, or on hogs perhaps?
