Rino:
No experience with the Vixen, but my favourite small-bore by far is a dainty Sako L-46 .222 circa 1954. It has the full-length Mannlicher-style stock, and wears a Pecar in factory-fitted claw mounts.

That little rifle spends most of its time hidden away in the gunsafe, since our local quarry are primarily buffalo and boar, but it has accompanied me on a couple of serious macropod culls with 52gr Sierras and performed flawlessly.

If the Vixen is even half as nice as the earlier L-46 I think you might enjoy owning one!
