All the same rules apply to coated bullets as cast bullets. That means you need to be .001" to .002" over bore diameter, the leade has to offer a smooth transition from chamber to bore, the bore has to be smooth, etc. You will get leading and/or coating gunk if something is off. On the positive, powder coated bullets are more forgiving of lead alloy softness or hardness, handle higher velocities, and can leave a bore cleaner if everything is right.
I suggest shooting a bunch of your loads without the suppressor to make sure there isn't an issue before attaching the suppressor.
