unless you decide to tell Leos you used reloads, why would it ever come up? Maybe they would ask this or check your ammo but I think it would not be something that would be of interest.
According to writings by Masad Ayoob (spelling?) Guns used in shootings are sent to firearms labratorys and the trigger pull is checked during analysis and the ammunition is also checked. We watched the entire George Zimmerman trial (wife&I both retired) and the tech. reported both the trigger and ammo were "In Spec.", so these things are checked as a matter of course. The reloaded ammo might be legal in itself but a prosecutor might/has argued that the handloaded ammo was meant cause more damage and was created in anticipation of shooting someone, or something to that effect. Unfortunately many jurors don't have a clue about guns and buy into the prosecutors argument.
For these reasons I only carry with factory ammo and leave my triggers to factory specification. I just don't need or want the extra hassle.
