I guess 2017-2019 is cheapest for most ammo
however from a reloaders perspective you have to consider the days when the gov allowed companies that de-milled their old ammo to resell the components as pull down.
buying real m193 bullets for $75/3000 in the early 2000s was a thing. 2.5cents each.
then buying primers for $14/1000 was 1.4 each
and powder could be had 8lbs for $50 or less. About 2.2 cents per round.
if you reloaded your brass, that’s under 7 cents a round, or $70/1000 compared to $280-300/1000 for new factory m193 at the time.
in the 90s you could go to knob creek and buy barrels of powder cheap.
