Does anyone have experience with a very light 12 ga. load that is commercially available? My wife has inherited a beautiful SXS from her father. It fits her like it was made for her. However, it weighs about 6 1/2 pounds. She wants to hunt grouse with it. I have looked at the Aguila mini shells in 7 1/2 shot, but there must be other "light" loads that are suitable to hunt with. I want this to be a pleasant experience for her. Any help is greatly appreciated.
