First some background, I've been using standard 12 ga. 3" steel 2's, I think around 1200 fps or so, 1 1/4 oz. This has been working ok,.. for steel.
I need a new case and was looking at the 1550fps 1 1/8 oz. loads. in 3"
So...with the extra oomph, can you go to #3 shot to get the pellet count up a little and still have adequate penetration?
I realize that the velocity falls off very fast on all these rounds, thus the need for the bigger shot sizes, just looking to gain a little benefit, especially with small ducks, but still enough smack down for the big ones.
The other non toxic alternatives are out of the question, thanks.
