Most underrated to me is the 6.5x55 Swede. In a modern action it has surprising performance. The old cip pressure rating of 45,000 cup has it castrated.
Most over rated is the 17 hmr.
Agreed! At least here in the US. There is something nostalgic about the 6.5x55 Swede and it's been around longer than our venerable .30-06.
