See the long post on AHN re this gun.

Q`s 1 are they worth the $3900 Aud asking price?
That's for you to decide. If you want cheaper, buy a Baikal.

Q`s 2 Are they quality rifles
You get what you pay for but Yes, for the price they are a good low cost DR.

Q`s 3 the calibre itself is it any advatage over the 9.3 x 62?
Yes, it's in a double rifle and not a bolt action.
If you are capable of putting the bulet where it is supposed to go, the game will not notice any difference. You have the same choice of everything - 250, 286 and 320 gn bullets.
