I don't understand why guys shoot designer loads. If you shooting birds in range 2 3/4 4's will do it all day.
I primarily shoot 2-3/4'' for anything and everything, including geese. The people that I've talked to about Blindside are primarily negative on it and say the pattern spreads rapidly. I'm betting there are trial boxes of Blindside that have been shelved into dark corners all over the state.
Cubed shot is a very old school solution for short range spreader loads. I'd like to see what it does on paper, especially in the smaller shot sizes. Just don't want another partial box taking up shelf space after testing.
