Probably 90% of what comes out of my 45ACPs is plated. Either Rainier or Berrys. As long as you keep velocities below 1200'ps, the plated bullets are great. Considering you'll never hit 1200'ps with a 45 ACP, load away with any current data.
FWIW, I use a lot of the 200gr HP Rainiers and accuracy is match quality with groups less than an inch at 25 yds.
