Back in the Black powder days, a BIGGER bullet was BEST...........for those long kentucky rifles, and that train of thought carried over.
Many thought the 200gr lead bullet was the cream of the crop back in the day, before the invention of smokeless powders and higher velositys started to rear its ugly head.

One reason the old Colt Peacemaker was a prize for anyone that had one.......though it was a .45 cal.

High vel copper bullets did not happen til around 1935......when S&W came up with the .357 magnum.

Midway has a 200gr lead with a GC, I have not checked other dealers, since I don't think the GC is going to be needed in a revolver.
