I know that some local shooters are running 125s crimped in the cannelure grove without problems. Personally, I run a 140 gr or 158 gr crimped in the side of the bullet at a length of 1.52. I started using this length because it ran well in a 1892 I had at the time. It also runs perfectly in an 1873, 1866, and a Marlin 1894.
Yes, I know I really didn't help you answer your original question.
