Hopefully no one was injured!
Was that particular weapon returned to Savage for analysis? If so, what were the results?
What was the projectile, powder and load combination?
Not being comfortable with loading smokeless powder, I would also only use BP or Substitutes in the 10ML.
Although I know a guy that does use (alot) of smokeless powder in his 10MLII and loves it with no issues. He is a very experienced reloader though.
