RE: .243 or .308??
No contest here at all. The 308 is a lot more gun than the 243. At any distance. Its one of the best long range caliber for deer that you will find. This is evident in the fact that its by far the most popular cartridge for the 500 meter Steel silhouette shooting. The 260 has now moved into second place in this game. nudging out the 7mm-08.
