There use to be a handy chart on the back of the Dillon RL550B instruction booklet. I made up a list to show the parts for every caliber I reload for and in which conversion box the shell plate, pins, and funnels could be found. There is a lot of cross usages as a lot of cartridges are based off of 30-06, 308, 38, 44, and others. Often times when I add a new caliber for me I only have to buy maybe the funnel or the shell plate and use the parts from other conversion kits. Since I reload for over 30 different cartridges and a lot of the press parts are interchangeable, I minimize my costs that way.
The link might be another way to keep track (??).
