i had a barrel sent to carlson several years ago and had it cut down and fitted with a turkey tube for
hevishot.it will handle about anything you put through
it.you could email or call them if you are
concerned.my understanding is the any tube developed for steel or hevishot will handle about anything out there.the older tubes made for lead or copper plated might be suspect but i shot hevishot through my rem super full for lead for years before switching.
i shoot a brwg auto and a rem super mag but use a tightwad .660 on my rem and it has an awesome pattern with #5 fed heavyweight.
