I bought one @ a LGSmith's shop a few yrs back, I remember asking him what he thought about running 410 slugs through it, he told me....the 45 Long Colt is your slug..., probably as honest an answer as there is. Other than short range I never had much luck with the 45's (would be nice if it came tapped like the other survivors), and the rifled barrel choke leaves it fairly opened up for shot. For myself, I found that choked it makes a great yard / garden gun...#12 shot 410 Rio's for close stuff, and CCI 45 L Colt #9 shot shells for even closer shots...
