Re: Please help me pick the right Caliber
I immediately thought about the .243win when I read your post, but it is a bit overkill for the squirrels etc.
How about a good rimfire for "the fun factor", like a 22mag or 17hmr. That would handle all the small stuff and closer range fox etc. Ammo is cheap. Then a more purpose oriented longer range rifle. Depending on the number of rounds you want to fire, a 204ruger would be awesome for a barrel burner. .243win would be great and would double as a light deer rifle.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
