One reason for picking a .38 for .38 shooting over a .357 is that you
will eventually erode the chamber area in front of the .38 Spl case.
This results in difficult extraction of the longer .357 Mag cases. How
often does this happen? Not very. But it was either J.D. Jones or John
Taffin who reported it happening to them. My guess is that you would
have to shoot a lot of the .38 ammo, tens and tens of thousands of
rounds before it would become a problem.
