This is not a money making Government Conspiracy, Rebel. Glen Sanderson published an incomplete data set he was working on while studying the mortality of waterfowl from lead. He over estimated the number of ducks that died from ingesting shot, and under estimated the number of ducks that died of lead poisoning from wounds received during hunting season. The EPA types got a hold of the data, and pushed through a Federal law requiring non-toxic shot be used in shooting Waterfowl. That gave us Steel shot regulations, and attempts ever since to come up with something better, that can be used in the older guns, including muzzle loaders. Glen eventually found that the mortality of ducks and gees from ingesting lead was so low that he could not conclude that it did add significantly to the mortality rate of the animals, as first believed.But, by that time, no one in Congress cared what the facts actually were. The Anti-hunting and anti-gun forces had their win, and they were not going to give it back. The facts be damned!
Hevi Shot, and this new shot by Winchester seem to the be the best promise. Bismuth shot is too fragile and fully 1/3 of the shot crumbles on firing due to the sudden push from the expanding gases. You lose all that shot from the down range pattern. Steel shot just does not retain energy over long distances, and is basically useless after 45 yds, no matter what size shot you use, or how much you send downrange. Hevishot( [polymer/iron) is slightly heavier than lead, and reacts to the traditional choke measurements for lead shot similarly. This new Winchester shot is expected to behave the same, but be better on the older steels used in waterfowl guns. We will see. The more shot is bought, the lower the price will be. Until a market exists for a product that allows the maufacturer to make enough product in quantity that his costs of manufacture come down, he has to charge for the small run work involved.
THAT, and only that, is why the price on new steel- alternative-shot tends to be so high. I remember when Bismuth shot first came out. Waited 2 years to see some of the stuff. The cost was terrible, but it has come down as more people have bought it. Hevi-shot is the same. I expect the same pricing will affect the new Winchester shot until volume sales bring the cost of production down.
