I owned that same rifle but sold it a while back. Nevertheless, I loaded 168gr BTHP bullets into it with very good results, F-210 primers, IMR4064 powder, OAL around 2.810" but best measured by ogive for real consistency. The rifle I owned liked powder charge near IMR's maximum limit I loaded it 45.6 gr and max is 45.9 according to IMR specification and achieved consistent 0.7-0.8 MOA accuracy and 2810 FPS velocities. CZ makes very good barrels, well stress relieved so it holds consistency even when warmed up but it may or may not like to maintain a bit of copper layer in the bore. Mine shot best 20-120 rounds after good brush & clean up. Between 20-120 just carbon clean up, no solvent but you may need to watch what yours will like.
