Does anyone have a m13 or 65 .357 that can measure the cylinder length? I'm curious to whether the m10 38 cylinder is the same length as the m13/65 357 cylinders.
Lol my brain has been down this path before.If I can find my caliper, I can measure both. Until then, I found this from 2013.

Why would anyone want to do anything? And why would you think it would blow it up, because SAMMI lists the 38 at 17500 and +P at 18500? In the beginning the 38 was regularly loaded to 20k right? Also the 357 came about from reaming the cylinders on a 10-6 ? I don't ever remember reading that one of those ever blew up. So my thinking is there is no heat treatment difference in the 10/64's and the 13/65's. Only difference is length of forcing cone to accommodate a slight increase in cylinder length. And that probably came about to keep people from making the conversion.My question is, why would you even want to try it? Why risk blowing up a model 10, or at the very least, ruin a model 10 cylinder? Why not just buy a used .357?
