I'm confused, you said that duty rounds favored faster times on the comp? That is the only place I'd expect much difference and the main reason to run a comp. Did you have reliability issues with the duty ammo? Run any +P duty ammo? I see little point running a comp with range fodder but would hope the comp helps the 365 run well with duty ammo and shoot softer simultaneously.
I didn't run +p (only because I don't have any)
I did have issues with some duty ammo as gun got dirty.
