For me, a long shot in the wind is 400+ at a woodchuck in rolling Va farmland in the summer. I have ZERO experience with 6mm and 25 cal. I go from .22 to .30 in most everything I do. I do carry a 6.5 x 55 when it rains though.
In the 50's the .22s died along with the 25s because of the 6mm.
Do you think Warren Page was a know nothing...It was his idea.
I got a swift because it was cheap, and did what I wanted to do, which was pop woodchucks. Not a bad way to spend the day.
Guys were trading in .22s for 6mm just like the short magnum craze now.

You appear to hunt more than I. You certainly spend more time at the keyboard than I, but I'm retired and can spend more time here than when I had responsibilities.
