It is a very good and very interesting question that like you said, is difficult to answer. I did a lookup on an inflation calculator and that didn't help. I have seen documentation that a rifle in colonial times sold for around $8.00. Which according to the calculator is now about $145 dollars, which doesn't seem helpful. Most working people on the frontier in those days, rarely would have had one dollar in "extra" money to spend on much of anything, let alone 8 of them so for the average working man or farmer, a gun, unless of the poorest sort may have been out of reach. The frontier economy was mostly barter and trade so that opens up more questions. (How many bushels of corn for that thar carved, engraved longrifle mister Dickert?) The idea that the average farmer hunted for his food with his longrifle is romantic and colorful but probably not accurate, at least until later when the economy began to improve. Farming meant working from first light until dark in those days, 365 days a year. Not much time for hunting for the average guy. But on the other hand, rifles certainly existed and someone was buying them, you might have opened up an interesting topic for debate.
