Educational? Period correct? Neither ! Horrible!

a .44 caliber pistol is referred to as a muzzle loader when cap and ball pistols cylinders were loaded only, nothing is forced down barrel. In one or two episodes Kate has a telegraph right in her rental farm house, ridiculous! Guess Pinkertons didn't pay the bill because later it is gone. There is no end to the inaccuracies. And some folks refer to this show as educational. I gave it 1/10. A better show of about the same time period taking place in England is Ripper Street.
