Pete,
I have a mix of pre 64 Winchesters, CZ 550s and Kimber Montanas as well as a Husqvarna 4100. It's not brand loyalty so much but it is obvious that I prefer CRF and Mauser style actions. I do not like removeable magazines. My rifles must fit and function reliably. My scopes are simple and mostly fixed power.

If I were hanging out in brown bear country, I'd probably have my 9.3x62 in hand but I'm usually more concerned about bullet than cartridge.

Of the rifles listed, none can readily be bought new off the shelf except for the Kimber Montana [perhaps].
