Don't feel bad Destry, I had a crippled Ringbill get into a passing raft of coots that caused the demise of an innocent coot bystander. 10-bore caused collateral damage, I fear.
We shot enough ducks to where I was so low on non-BB shells that I had to make a side trip to town for more, late one morning. Ended up with some rather pricey Remington 1 3/8 oz. #2 steel loads (it was all they had) that were rated at 1500 FPS(!) Somewhat unpleasant to shoot (the dang thing sounds like a rifle with 'em), but pretty effective.
