I just got a JM625 45acp Smith and Wesson, and revolvers are far less picky with Overal Length than Automatics. so Im wondering how to determine ideal bullet seating, aka OAL.

With my rifles, its a process of loading a dummy round where I mark the projectile with a black marker and observe where the projectile is scratched after chambering it, then measure with a micrometer to dial in the exact OAL where the bullet just seats under the ogive...., chambering it, an ideal point where the bullet wont vibrate any more than necessary as it leaves the chamber.

Revolvers are not like autos where the OAL needs to cater to the confines of magazine feed and feed ramp.

So, whats the method of setting OAL for a revolver?
