While I am no expert and don't claim to be, I have been shooting and loading shot loads for 40 years in 22, 38, 357, and 44. I have used plastic capsules, crimped, small lead plugs, lead round balls, cardboard, and even plastic as cartridge caps to contain the shot. I have also loaded shot sized from 00 to #12 and mixed them as "duplex" loads. I would not hesitate to shoot any and all of these in any of my modern (50+ year old) revolvers.
