I will second Jeff's comment on Bill Woodin's collection. Picture a room with an island of cabinets in the middle. The cabinets house drawers designed to hold mechanical drawings and are about 2 inches deep by 2 feet wide by 18 to 24 inches front to back. The island is 50 ft long by 5 feet high and has two rows of cabinets back-to-back so half of the drawers open to the north and the other half opens to the south. All of the drawers are full. Ammo is collected for any difference, so headstamp, primer color, primer annulus color, bullet type, etc.
Dave, you have one 25mm telescoped round for the F-15. Bill has 6 or 8 at least. I think he stops at 35mm, but it might have been lowered to a smaller diameter caliber due to space restrictions.
