Trailer, I can not go as far as to say that any factory SS barrel is perfectly fine. I would attempt an edcuated guess that in the companies interest they would not push the barrier of common SS barrel practice simply to prevent any lawsuites stemming from a barrel malfunction. Personally I would try to stay away from Ultra Light or super thin tapered SS barrels even from the factory. If well known companies that produce high end aftermarket barrels are not willing to stake their name on the thin SS barrels, I'm not so sure I am willing to possibly stake my life on it. I am not qualified to judge SS as I am not a metallurgist, I am just pointing out best practices of well know companies regarding SS barrels. I would read what others have to say on the topic and possibly consult a custom barrel manufacturer via phone, most are more than willing to answer any questions that you may have. I would trust the folks that produce barrels for a living.
