Do they ask you if you shot reloads in it? If not, how could they possibly tell? My reloads don't shoot any different than ammo made by Wolf, Remington, Prvi Partizan, Federal or Winchester . I have sent several guns back for repairs over the years and not once has a manufacturer ask me if I shot reloads in them. Perhaps if I was loading extremely "hot" loads and had damaged the gun then they might have asked. Had this happened then I wouldn't expect it to be covered under any warranty (same as someone buying a $500 pen, dropping it on the floor and wanting the manufacturer to fixe the pen under warranty). If this were to happen then I wouldn't blame them for voiding the warranty. If you are really concerned about this then just shoot commercial ammo in it (saving your brass) until the warranty expires and then shoot all the reloads like as the warranty is no longer a factor.
