I thank everyone for their responces and opinion. Somewhere in the MIX is the truth. Roy, I think that chart is great and can be interpreted in many ways.
i:e I shot a 10 ga. and now I know why so little amount of ammo sold.
Recoil Rob, I look at the ammo sales as my answer to the # of european guns sold. When I compare it to the sales of 28's in the US only Parker and Ithaca made them and in very few numbers. LC Smith and Fox did not at all. It seem to me from the ammo sale #'s that it was pretty much the same in Europe.
