Sounds like we've gone through a somewhat similar transformation. While I still have several rifles chambered for magnums and medium-bores from .30 caliber to .416, they're mostly kept around for test purposes, since I haven't hunted with any of them since 2011. The "big" rifle I've hunted with since then is a 26 Nosler, and it hasn't gone hunting nearly as much as several other rifles chambered for smaller rounds.
This makes perfect sense in today’s “age of powder and bullets.” We get all the power and penetration we need out of much more sensible cartridges.
