I never caught magnumitis back in the days when a few new magnum cartridges were being brought out every year. Even when I lived in Kodiak I didn't feel like I needed a magnum when I Brown Bear hunted. I have no idea how popular any of the cartridges are as there's simply not much data out there to draw from. It does seem like when I look at store shelves there are fewer magnums in the racks than there would have been 10-15 years ago. Good bullets, well placed is what it's all about.
