I think rem was right track with their classic line, offered in a unique chambering annually. folks bought those rifles just to get the chambering and start a collection.
winchester should have done the same. I would have bought one every year.
my win classic list would have looked something like this;
220 swift
240 wby mag
257 roberts
257 wby mag
264 win mag
270 wby mag
7x57
300 h&h
I would have to be creative from there!
