Bill, shooting from a blind, M/F is too tight around here. These old guns produce gobs of shot that pulverize. I've had whistlers shot so badly that my Lab would gag and spit them out on the shore, literally flattened, and wouldn't bring them into the blind. I eat ducks; I like to cook them. Before I die I'll screw up the courage to open one to C/C with the expectation of a grandchild gunner saying one day "This was Grampy's favourite duck gun." Immortality!
