Best 2 3/4 inch ammo for geese?

[Deja vu]

I am willing to pay for the expensive ammo but I have an old shotgun that I want to try hunting with that only accepts 2 3/4 inch rounds. It is steel safe but im willing to use the heavy rounds.

p.s. no lead shot allowed for geese.

If you use BB steel shot you'll be limited to an effective 25-45 yds .It may be less ,you have to find how it patterns.

I would use #1 Kent Impact or #1 or B Hevi-Shot goose. In fact I do. The Duck and everything else with Hevi-Shot is lighter.

I would use something like Hevy Shot or Bismuth #2's or BB's. I like the non-toxic pellets with the characteristics of lead. As someone mentioned above, distance is a critical factor.
