I've been using 10.5 grains of W296 under a 45 grain Sierra Semi Point with good results out of a Browning 1885. I just had to mount an old Weaver K-10 60B on it for looks. We don't have wood chucks here in Miss. but it works well on coyotes and other varmits. I never thought of it being difficult to load for but I had heard that it was one of "those"
