I use Bullet File and have my collection in wooden display cases and cabinets. I arranged and set my collection up by assigning a number to the case, row, and bullet. I then type and have an inventory for that cabinet/case that will correspond to the bullet file number. You can either reference the bullet by Id or Inv number from the bullet file. I have enclosed a photo of a case of bullets from a certain location and for example I can look at the inventory sheet I have associated with the case and immediately look at a specific bullet and refer the bullet from the inventory to the printed copy of the bullet file. For example I can look at the bullet in Cab 11 Row 4 Bullet 6 and get the Inv number and go straight to the correct page and have all the information immediately. With the photo attached if I want details on a certain bullet I can go to the Cab and get the numbers by Cab 11 Row 4 Bullet 5 and the corresponding Inv # which happens to be Inv # 1140 in my collection. I take that inventory number and go straight to the hard copy of the bullet file I keep in binders and find Cab 11 Row 4 Bullet 5 and can retrieve any information on the bullet I am looking for. Like its a MM-350, Lube Groove, dug by xxxxx at Crump's Hill, paid $, current value $ and and any remarks you wish to add in the detail section. I happen to reference the MM and TT in the section on the bullet file page and then in remarks I add Tom Stelma's and RBTRF Vol I,II, III, IV and bullet number plus cavity depths, damage if any on bullet, etc. You can also reverse the process and say you want to look up information on a certain MM/TT bullet in your collection just go to the MM/TT list arranged by Bullet File and find the cab/row and bullet number and you can go straight to the bullet. Wow, I hope I didn't totally confuse everyone because I think I confused myself.
