According to a 1902 Sears-Roebuck Sporting Catalogue reprint:
Winchester single shot, (I assume Hi-Wall) $10.69,
Winchester '94 in 30-30, $14.75
Winchester '95 in 30-40 $21.35
And you mil-surp fans will love this, surplus spencer rifles, $3.65
I was guessing a dollar a day was good wages during this period for a laborer, if anybody has a better guess, pitch in.
If I am right, it would cost the better part of a months pay for a "Modern" high power rifle, but you could get something that would work well for little more than a weeks pay.
Wouldn't it be great if we could currently buy a quality single-shot for less than the price of a 30-30?
