Lead buckshot and slugs with fins on them are fine for full chokes.
They compress as it goes through the choke.

Nickel plated steel shot is more likely to fuck up your choke.

I'd like to try 28 gauge Thug Slugs after i got such good results with the 410 ones, but the 28 version will be dificult to source.
