Hard/far left upon entry usually gets you to many ammo cans, immediate right/close usually has a guy with powders, bullets prob at the far right rear wall, just past J&C Sales' good ammo tables. I rarely reload so others are prob scattered about. Cheap scopes, new/used are all over.
Go early and move fast before it clogs up later in the am, then re-hit your marks. Small parts sales are prob best with a note pinned to your coat.
PS- Berea this weekend ohiogunshows.com has many of the same dealers
