I use 2 pieces of an egg carton florescent light cover cut to fit in the bottom of an old cake pan for sorting brass
Shake it as I pour the brass across the grid, most of the cases drop into it base first. The few that don't are simple to flip
The differences between 9mm/.380/9mm Mak; .38/.357; and .45 acp/.45 GAP are easy to spot when you look across the rows. Plus the cases are all mouth-up, so it's easy to inspect inside. Then carefully lift lift the grid off of the cases and spray a little One Shot across the batch from a couple of different angles to lube the sides and get just a touch inside for resizing (make sure the One Shot has time to thoroughly dry before loading).
(No, I've never had a FTF from the powder being wet by the One Shot)
Still hate the small primer .45 acp, but do have a few hundred stashed on the back shelf-- 'just in case' another LP drought comes up.
