I like them all but it is easy to see why the 6.5s are getting the popularity they deserve. They have a good balance of high BCs and lower recoil. They are suitable for almost all non dangerous game. My favorite is the 7mm but with 175s and above in a RM recoil starts to be a factor. But anything between .17 and 50 caliber is good. I could do most of my hunting with a .23 and a .29 caliber rifle.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
