I too gave up on the switch barrel routine years ago. To me, it was more trouble than it was worth. Added to that, the rifle I needed at the moment was stashed away in pieces. Now, they're sighted in and ready to go. The ones in my "Ready Service" rack are loaded too. If I need a 400 yard shot on a coyote, I'd probably grab the .22-250 or .243. A woodchuck at 300, I might use a .45-70 for giggles. Anything at 200 is fair game for any of them, maxi, .30-30. .356, etc.
