I am not 100% positive about the .410 slugs as I had an adjustable choke on my 1950's .410 bolt gun but I fired many thru it with the choke cranked full tight. On a bigger bore gun, the rifled lead slug is safe thru a full choke as the rifle grooves are there to allow the slug to be tight fit in an open barrel but swage down in a tighter constriction.
