I stumbled on a nice Ithaca flues

[Mike of the Mountain]

John Davis posted some 16g loads tested by either Tom Armbrust or BP. 2 3/4" hulls, 1 oz and Longshot powder and were in the 6000 PSI range or less. I've been using those loads for clays and hunting and they do shoot great in my Parkers and Lefevers.

So my #2 Flues was made in 1913 with the Krupp barrels, would it be a Krupp Pigeon?
