Reading back a little further, Bangaway, you asked about my experiments with bullets up to 140 grains in the revolvers.
The bullets I've used were the Lyman 311410 (about 130 grains) and a custom made mold that weighs 140 grains and has 4(!) crimp grooves. Both bullets did fine at low (800 FPS) velocities from my large frame Rossi, (it has a fast twist, at 1-12") but didn't fare as well at low velocity from any of the other revolvers I own.
They were alright when pushed hard from the Ruger Single Six, but at anything much less than 1100 FPS, were unstable at 25 yards. At 1200 FPS, both bullets were accurate from the single six at 25 yards. I loaded them in the magnum brass, and seated them long, and with a load of powder that would no doubt make the SAAMI boys cringe. They flew down range, and made nice little groups on the paper. I like the 32's for their mild report, among other things, so I'll leave the heavy bullets for heavier calibers generally, but it's good to know that they can be made to work in the Single Six if needed.
Even loaded hot they were both keyholing from the taurus 32 magnum, and I wouldn't try them in any of the older/weaker guns. Besides the obvious safety concerns with the over spec pressures, I wouldn't suspect them to be very good, with the slow twists, etc.
