They are indeed, David!
Susie hasn't been used on doves yet this year (2022-2023 seasons) but will when it comes back in. Our first season is out right now, and I typically shoot nothing but .410, 28 and 20 gauges for doves in the early season. Middle season I'll start with the 16s and continue with them through the late season. Occasionally, in the late season when the big northern doves are passing through GA I'll use a 12, particularly on cold, windswept days when they're flying fast and high, never with over 1 oz. of shot, however.
