3 Grey ones MTM are for all rifle and 38/357 on one side. The other side is for 9mm and 45.
The 2 Midway ones are for what is noted on the backside of them.
The 2 Oak trays were made by me for the .45acp, but they will accommodate many size cases.
And the long Oak one I made for some .22 experimenting that I was doing.
Brass not included.
