I have a friend who has offered to sell me about 20 lbs. of bismuth BBs at a good price. While bismuth shot is both hard to find and expensive, BBs certainly aren't my first choice in size. I'd be much more interested if they were 2s or 4s. What do you guys think? Are BBs, especially in a 12-gauge, adequate for waterfowling? A load of 1 3/8 oz. delivers ony about 69 pellets, I believe, but then again, just one or two need to find their mark to do the job. I'm weighing the pros and cons and looking for guidance. Thanks in advance. TT
