Thanx for the replies guys.
I have been talking to a few gunsmiths and I think the better option for me is to have a Aussie gunsmith build the EDGE. I think by the time the rifle comes into the country I would be paying way too much on things like shipping etc. So for now I will see how the RUM goes. I seem to be getting about 2730 fps with the 300grn SMk and acuracy is pretty good. So I think I will wear the barrel out on the RUM before I build the Edge on this action.
As for the scope I have just put a deposit on a 5.5-22x50 NF NXS. Now just have to decide what to do with the spare 3.5-15x56 NXS I have.
By the way
Are there any NSW hunters out there who have room for another hunting buddy or two. The perks of working for the government is they give you more holidays than you know what to do with.
