The biggest difference I have seen is the size of the hole they put in your wallet. You do need to make sure any tube used for steel shot is so rated. I have shot hundreds of patterns with Browning, Remington, Brileys, TruLocks, Colonials, Carlsons, and even some RedHead from BassPro, and probably some others, and the only thing that matters is the constriction versus the bore diameter. I have had some custom bored tubes that worked perfectly for what I was doing, but that is a rare exception.
I did get a couple of duds, and spotted that before ever firing a round, but I won't say the names because I am sure I had the new ones in my hand before the defective ones got back to them.
