Do you have any specific examples of that? I know that 3031 is dangerous, even though it was recommended by Jim Bell back in the day. I know that R-15 with a wad is dangerous for ringing, even though many here and elsewhere swear by it for reduced recoil.

I have never, in close to 30 years of reloading and shooting Double rifles, mostly British, ever heard that 4831 was dangerous. In fact, if my memory serves Ross told me last spring that he likes it for the full case it gives without need for a wad. I have shot thousands of rounds in 30 or so different English rifles using 4831 and have never seen any type of problem. You have raised my curiosity and I now need to call Ross and Ken and ask them why they believe this.

A good topic for open minded discussion. Graham is known to many here as he is one of the original workers and writers in getting Double rifles back up and running, before the bandwagon Double rifle experts even knew such a thing existed. Ross has learned from his experience and I know has come to some different conclusions than Graham has. I do know he doesn't care for any man made plastic type fillers. Surprises me he likes kapok at all.

A shame that they both don't post here. It would make for an interesting discussion.
