I have not done much waterfowl hunting, but have been lead to believe that you need to use #2 shot when duckhunting. I have a recently restored 1914 VH grade Parker with fluid steel 12 bore barrels (30”) and I am looking at using with either Kent matrix 2 3/4” or Rio Bismuth also 2 3/4”, (RDT doesn’t appear to sell duck loads anymore) but l don’t seem be able to find anything larger than #4 shot? Also, the velocities are pretty high for an old gun, over 1,300. If I’m mostly going for mallards, what would you recommend I use at a relatively high altitude (Great Salt Lake)?
Thanks for your advice.
