Using new Starline brass, Remington small pistol primers, 3 grains of IMR Trail Boss, and Magtech 158 grain LRN bullets. The minimum COL (per Lee) is 1.475, however seating the bullet to this length places the only cannelure (lubed) way below the case mouth. IMR suggests a minimum COL of 1.445, so I'm not too concerned about that. I've only crimped the casings just enough to remove the bell. I'll be using a S&W Model 10 for these rounds - in your experience, do you guys think the bullets will manage to walk out enough to impede function of the revolver?
