Lee, I wouldn't worry about what the other guy was flapping his jaw about. You know how it is, there are some guys that just like to ruffel feathers. I was thinking along the lines you were. I also do the same for break in with ALL my guns not just muzzy's. When I break in a new gun I only shoot lead bullets out of them for the first go around.

I have no problem with my triumph and conical, the thing will shoot tight groups all day long. The gun is also very forgiving when it comes to cleaning and loads. I can shoot it clean or dirty and get results that are close enough to call good. As a matter a fact I have never fire a sabot from any of my muzzy's, I wouldn't know the first thing about them.
I thank you for your knowledge.
