I'm 7/9ths through with a revolver; but I'd like, Bossmanses, a couple of rulings before I continue.

1) Will you allow an exception of two guns?
My buddy was with me, with his young son, and he wanted to have the kid step up from .22's. But his S&W had been converted to DA-only, not really suitable for a small and weak learner, so I let them use my Security-Six while I shot several Pistolero Contest stages with his Mod. 66.
After they were done, I reclaimed ol' faithful and continued with stages.

2) Will you allow an exception of two ammos?
So far, I've been using 158-gr. LSWC bullets. But the sharp shoulders are hanging up on the reload stage, so I'd like to use something more rounded. (I don't know what I've got in the garage that fits the bill; I might have to shoot full .357 loads instead of the .38 Specials I've been using!)
That change alone won't shave the all of the 1.25 seconds I need to drop, but it'd sure help.
