Great Rifle, excellent cartridge choice, there again i am biased.
Here are a couple of pics of mine, virtually identical spec.
I have a Holland bolt handle and recoil lug fitted and a Rifle Basix trigger.
The Mount is a Warne Tactical coupled with Leupold MK4 rings and as you can see they carry a Leupold LRT With M1 turrets.
I have had excellent results using the Lapua 105grn Scenar ove 46grns of H4350 Ext.
Although only tested at 100m, with velocity at 3195fps, 1/2 moa accuracy, Extreme spread of 20fps and standard deviation of 9, this load has the potential for an outstanding long range performer.
