Reason I say pattern it, I tried two diff brands of non buffered #1 buck. Both pattern like crap in my 870 riot bbl. @ 10yds, lots holes in the pattern, w/ about half the shot missing. the 11x17 paper I use top pattern. All pellets should land center on that @ 10 steps. I am sure buffered shot would be better, but then it cost quite a bit more than most low recoil #00.
So #4 buck indoors, devastating w/o a huge concern for overpentration from pellets that may miss. Whatever you decide, stick to some size of buckshot, never birdshot.
