I shoot Ideal 121 gr home cast (bullets water dropped to increase hardness) from both my CZ 85 Combat and 75 SP-01 Shadow with no issue. Run them through a luber sizer to .3575. Seat depth is 1.111. These bullets are shaped like a Crayola crayon, so with amount of taper, they don't need to be deep seated like some other bullets when fired in a CZ. Best loads are either 4.1 Win 231 or 4.5 gr Unique.
Both shoot very well. At my 50 ft. indoor range, can't say that jacketed shoot any better.
One tip, if you shoot jacketed bullets primarily, give your barrel a very good cleaning before going to lead. Any copper fouling will act like a magnet to pick up lead.
