RpNY I shoot a number of the bottle neck cartridges of the blackpowder era. I can tell you that the case that comes out of the chamber is a lot more of a pronounced shoulder and neck than the unfireformed case that goes in. Much like the 30-30, if you look at the empty case that comes out after firing a factory load it's got more of a shoulder.
Still no matter how sharp the shoulder angle, blackpowder or the substitutes are not likely to damage a modern rifle with an unobstructed bore.
If you have evidence, real evidence, not bs urban legend nonsense, put it up for the rest of us to see, because there is no shortage of folks that do shoot bp in a variety of cartridges with no ill affects.
