Thanks for all the replies.
So far it is clear that an insert is not such a great idea after all, so that is out.
It seems that an O/U in 12 or 20gaX3" with removable chokes is likely a good starting point. Any suggestions about which brand/where to get are most welcome.
I will leave the .22 and .308 for a later time and then buy a "proper" setup for them.
I would like more pointers about how to start hunting and I'm intrigued by the comments saying deer hunting is a better start. I assumed that birds would be easier because a) they fit in an apartment fridge and b) I have seen/helped plucking/gutting when I was a kid. I'm under the assumption that a deer will need a sizable freezer and thought that learning to skin a rabbit would help (of course if there are no rabbits/hares then this is a moot point)
Thanks for sharing what you did when you travelled this road, it is very valuable to me.
If you want to buy a cheaper O/U that you will likely part with at a loss in the future to upgrade to something that will last any of the Turkish or South American imports would likely get you by. With Baikal banned from import parts may become hard to impossible to find in the near future, CZ or Huglu would be my pick of the entry market brands. I have bought used for a while and sold or traded off a few of the other cheap doubles out there and my loss on investment would have afforded me a much better gun with ease. A used Browning, Winchester, Miroku, Franchi, Beretta or variety of other still manufactured European and Japanese brands would be where I would put my money for an O/U.
Still like myself and other posters have said for the dollars invested you could get yourself a very good pump action with both a slug barrel and a smooth barrel that still breaks down almost as small and if it makes her feel better the trigger mechanism can be removed on most in seconds and locked separately as well.
