Hello members, I am looking at setting up my late father's L57 .243 (Serial#160!) rifle as a hunting outfit. It is near new as my father only went hunting pigs and 'roos for a couple of seasons before my sister was born in 1966. The rifle probably had less than 100 rounds sent down. I am impressed with the Leupold on my Lithgow LA101 .22 Mag, So i am contemplating a VX-5HD 2-10x42 as a scope, I was wondering if anyone out there has advice on the necessary rings (Leupold) or an alternative. The mounting rails are an unusual design. Delta shaped to avoid recoil slippage. From my post you may ascertain that I am not too familiar with the old Sako's. I have not ventured into a shop to look at the modern variants. When I look online and view rings, there is reference to Weaver and Pic rails. With this unusual shape, what sort of rings should i look at? Thanks in advance, and take care everyone. Regards, Mark.
