So finally got chance to get to the range and see how this goes... I did try sighting it in one evening but it wasn't the best conditions, got a really good group but then found the scope was loose so had to re do it all!
So tightened up the mounts and went to the range proper, perfect conditions last night... These are all 3 shot groups at 109yds.

Very, very happy with this rifle it shot all but one of the types of ammo well. I only tried it with the first load of the 65gr Sierra Gamekings I had loaded in the RG brass and although it shot very well, the primers are noticeably flattened. This RG brass definitely seems to have a reduced capacity compared to retail .223 brass.
