I won Gold Medals in Men's Individual 55-59 and Men's Team 50+. Due to the postponed awards ceremony, I will not be able to attend, as I won't be in the area. Can I authorize another athlete to pick up my medals?

I have a rules question. As stated, the event is a "no alibi" match. There is also a time penalty for not firing 12 rounds in each shooting phase. If a competitor attempts to fire 12 rounds, but suffers a misfire, can he load an additional round during that shooting phase in order to fire the 12 rounds required?
