Load one,skip one,load four more,cock the hammer and set it down on the empty chamber.
That is the correct way to do it if you are not under duress.
IF I was under durress, I would punch one out, reload one, and continue till all 6 cylinders are reloaded, or untill I was WELL under durress and might have to try and shoot with less than a full cylinder reloaded...
This is why I have not carried a single action for protection very much.
When I hunt with my single action 44 Mag or my 475 L I still carry my 4" S&W 44 Mag, or my 1911, depending if I think my biggest threat is BIG with 4 legs or a 2 legged varmint.
I just have to many years On The Job, to much time in Dangerous Places to use only a Single Action.
Now I will say Elmer Keith is one of my "heros", but He did not spend any time around Modern Drug Dealers...
In Todays World, the SAA is just not a Combat handgun, IMHO.
In retrospect I think even Custer would have chosen the 1911.
Well maybe not, as he left the Gattling guns behind....
Oh, back to the Single Action, if back in the day, and you were behind good cover, and shooting at a distance with your SAA, one good plan would be to shoot one shot, eject the empty, reload, shoot the second shot, eject the empty, reload and repeat...
Then when/if there was a charge your SAA would be loaded with at least 5 rounds... Think about it.
Also think about Josey Wales, He carried at least 4 sixguns.... Not a bad plan.
I would want a Winchester rifle as well...
