As @drband points out, the nominal diameter for cast is .452, but as always when switching bullets, you still need to do appropriate load work ups. You still need to determine max and working COL for the new bullet and do the powder work up. Some run plated quite hot, similar to jacketed, but if you check published data there’s a difference between cast and jacketed data. Be safe and good luck.Will that cause me any issues going from 451 to 452??

I agree. I wasn’t advocating driving coated to jacketed velocities, rather the OP’s plated load workup may not be appropriate for a coated bullet.However, I don't think you will ever drive a .45acp COATED bullet too fast if you are working up a SAFE load.
i second that.Plunk test them because some guns may have a "tight" chamber and you may encounter thicker walled brass and together may not allow a good plunk test...
