.243 vs .308 Win Caliber Comparison: Ammo Guide for Hunters

"These two rifle cartridges offer a wide variety of ammo to meet your needs for varmint hunting. From Pronghorn to prairie dogs to antelope to Whitetail deer, no varmint is safe from the 243 Winchester or the 308."
If You only have 1, I can understand the argument for the .243. On the other hand I have a scoped .17 for varmints, and a .308 for the serious stuff. A padded Hunting coat doesn't cost as much as a new rifle, I don't think anyway.
