The phrase "working rifle" is used by many people. What exactly does one classify as a working rifle?
I think that this term, "working rifle", exists on all continents and in all hunting cultures.
This is rifle which is owners favorite, or his only rifle, it is reliable, at least reasonably accurate, with sufficient power for all game, that owner hunts, and when it drops to the ground, or stock and bluing gets scratched and worn out - owner will not cry about it.
It can be ruger R2 american rifle, or it can be Rigby. Price and value is irrelevant
It will depend on owners feelings.
Something that owner (hunter) is using everyday in the field, like the soldier on front line will use his one and only military issued rifle for all situations.
For civilian hunter there are "working rifles", "safe queen rifles", "collection rifles", "specialized rifles" for this and that, driven hunts, or DG, or pests..., etc ... which is the luxury of some of civilian owners.
But working rifle can be described by relationship of its owner with it, first one to take out, and other rifles only on special occasion, if there are others, and if taken out - at all.
