I have tried both in practice, not in hunting.
Am curious, anyone hunted with both yet?
Any opinions on which one you prefer?

Personally, I will be using the Heym Martini as it seems to "flow to my shoulder" very well. Action is perfect and the overall package is accurate.

I like the Rigby, more for the name, but do like the craftsmanship.

Opinions?

I have not used both but I did handle both before purchasing a Heym 416 Rigby Martini Express. I have not regrated the decision. My 416 is a consistent minute of angle shooter and the slickest cycling bolt action I have ever shot.
