The original suit was related to a barrel burst in 1983 with a second hand 1100 in the hands of a trapshooter using RELOADS

Loitz vs. Remington Arms, 1990

Lots of stuff out on the internet, including previous discussions here.

So back to the question. My opinion is just that and of no more weight than anyone else's, but I would be very reluctant to use anything but quality steel target loads in a barrel that was not Chrome Moly or Nickel Steel.
