I loaded 2-3K frangibles w/o any issues. Just used the medium load data for the weight. You need to use care in crimping as some frangibles may tend to be brittle causing them to break off at the crimp(not usually seen with taper crimps).
FWIW
I've had good results using plated bullets on steel. They tend to "moosh" or "washer" rather than rebound as lead or jacketed bullets may do.
