In the old days a case of shotgun shells held 20 boxes of 25. Now a case holds 10 boxes of 25 and is what in the old days was called a flat as the case is flatter by 1/2.
With regard to swollen hulls, the Army had this problem with the high humidity in Viet Nam, so they switched to all brass shells. (It's only tax payer money.) They are neat, but I don't know how or if they can be reloaded.
I reloaded paper shells in the 60s. I don't know how many times I could reload one shell, but I shot them until I blew the end off.
