If I was going to trim it would probably be with .357 Sig., but I've never loaded any .357 Sig. Hmmm. Probably wouldn't be a bad idea with other bottleneck pistol calibers but I haven't loaded any of those enough times to worry about it, yet. Revolver brass needing crimping can benefit from trimming for consistency. The whole subject probably boils down to what you think you're doing...
