Driftrider, thanks for all that information. I have two traditions inlines the long distance and the Champion 2000. The long distance seems to have the same barrel as there latest Evolution Premier that is advertised for 150 grains. My manuals both have recommendations to use 100 grains or less. Go figure??? I also would like to know what Winchester has to say, Please keep us posted. Here’s an idea, can we start a pole on this thread with our names and concerns and send it to Winchester demanding an explanation!!! May be one of you experts can word it properly.
