I have a 105 in creedmoor, and another former workmate has one in 308, we are both actually club members of Lithgow Small Arms Rifle Club which shoots on the Thales (they own the Lithgow/ADI brands) owned range in Lithgow. I have put around 200 rounds through it, mostly Hornady American gunner 140gr HPBT and some of the 143gr eldx hunting rounds. I lightened the trigger weight and fitted the larger grips, other than that it is pretty much as it came. I have a Harris swivel bipod and have a small Caldwell rear bag, I will buy an adjustable rear bag platform. I have what would probably be described as cheap shit/beginner scope here, Zerotech trace advance 4.5-27×50mm, has tracked fine from 100 yard zero to 900 yards and up and down a few times, can't complain with picture quality, can pick up mirage at different distances with focus adjustment and easily see "fouling shots" fall on the berm. Don't use muzzle brakes at club shoots so I probably won't shoot it much with the brake. Recoil pad is good.
I just used the hornady website calculator for ballistics and velocity data from zeroing at a friend's place and it has been within a click or two on the scope out to 900 yards, temperature seems to be the biggest impact. I should be set up to start handloading by Easter, living on my own place with room to shoot out to about a mile.
Very much aware I am the limiting factor at the moment in terms of technique, living/safe storarge arrangements didn't allow for dry firing practice which I need to work on. Never had a problem with general functionality of the rifle, feels well balanced if I want to shoot standing for field class but 223 and 308 ammo are cheaper and I have several rifles to chose from.
The only fiddly things I have found is that the cheek riser must be lifted out to remove the bolt (range rules to clear rifle before leaving the mound on each stage, in saying that with my scope/mounts I have the riser bottomed out anyway) and single feeding the American Gunner requires the round to be placed in the right spot on top of the magazine follower (fed perfectly from the magazine), the eldx fed fine single without concern for placement.
