I used last year #2 (It's the same as Havi-Shot) and at 45-50 yards dropped a goose like a rock (I could never get goose from one steel shot at that distance). I do not think I would go lower than #4.
Not to try to steer the topic, but we all know that steel shoots tighter then lead: so IC lead=Mod steel. What about Hevi- Shor and Remington HD. Whould I use choke based on lead or steel tightness?
is true IC lead=Mod or even Full Remington HD (hevi-shot)?
