I just recently picked up a CZ527 Royal in .223 with the 1:12 twist barrel.
It loves 50 gr ammo so far.
It has a kind of a unique stock with a lot of drop on the comb so I had to put a cheek riser on in order to get better than a chin weld. The new cheek riser worked out nicely because I could adjust the front and rear independently.
I put a Nitrex 6x20x50mm scope on it , Harris 6-9" swivel bi-pod and used CZ rings that just barley gave enough clearance for the scope objective .
I can shoot a 1" smiley face sticker all day long with it @ 100 yards
I know what you mean about how light the set trigger is but it makes it nice for bench shooting.
