I match the rifle, cartridge, and load to the type of hunting that I'm planning to do, sort of like matching the hatch when fly fishing for trout.

I'm not particularly tied to any single rifle, cartridge, or load.

The one rifle that always travels with me is a S&W C in 30-06 with an old, pre-'74, Vari-X II 3-9x40. It is a dependable spare or loaner.
