I'll second the vote for RCBS 210 grain. It worked well for me.
If you go heavier, try buying commercial bullets in whatever weight you want to use and make sure the handguns under discussion have enough sight adjustment to land them at point of aim. One of my two Ruger Blackhawks back in the early 90 was essentially out of adjustment at 210 grains and the other probably wouldn't have zeroed beyond 220. Heavier would have only worked if I replaced the front sights or used optics.
