Everything you use except for that days gun(s) and ammo should be in a box. I use one of those big blue plastic ones that has the folding "fingers" at the top
Scope, rests (several), extra ears - muffs and plugs - in case kids/grandkids are coming, extra safety glasses, targets, cleaning gear, some basic tools/screwdrivers, tape or stapler, an extra 250 round box of .22 - sometimes those kids go crazy!, empty 25# shot bags to hold and segregate brass, a marker or two, rag or two, and a folding mat to lay on the table top
Where I used to shoot a lot, the bench tops were concrete so a blanket or similar kept the guns from getting scratched
