Have had some very accurate,easy to cast/load for handguns.A particular nice one is an old 744 DW.It's neat to see from a heavy BR style rest,the weight of the 429421's ...... with a cyl full vs picking one chamber.With a cyl full,you can see the effect of the weight change of cyl as it unloads.Shoots predictable round patterns,like those old trick shooters punching out faces N such.IOW's...the round group "clocks" in a circle,not random displacement. It's repeatable,that's how accurate they are with 429421/2400 loads.
Single cyl loading is one ragged hole.But this was back when I was going through handgun ammo.Put 15k rounds through a Python in one summer.98% of my handguns loads were CB's.Was shooting mostly outdoors but that's when I built our first indoor range so we could shoot at night too.Good times.
