What is the widest, most popular cartridge loaded on a 550?

[SlammedDime]

I had a nifty idea for a non-collating case feeder for the 550 to help speed things up a bit and I don't just wanna limit myself to .40 and .223 (what I currently load), I'd like to make it easily expandable. Looking at rough measurements, it looks like I could design it to hold cases up to .50" in diameter... would this be sufficient or would I be missing any popular rifle rounds?

If the design can only handle cases up to .50" in diameter, then that would have to be sufficient by definition. Besides, is there a general market of reloaders making >.50" calibers who need case feeders? I don't think of those big calibers to be volume production calibers for home reloaders. Thinking along these lines, let me offer a different way of viewing the problem: What is the largest caliber that people tend to reload so much ammo for that they'd pay money for a case feeder? That can give a very different answer than merely not wanting to miss popular caliber sizes. For example, the .45-70 is a popular caliber, but I doubt it is a home volume production caliber.

I'm not necessarily looking at calibers, but actual case's base/rim (whichever is larger) diameter (.223,for example has a rim diameter of .378") as I need to determine how many tubes I can fit into the rig. I may be able to make it so the smaller the caliber, the more tubes of cases will fit... IE: 3 or 4 pretty much... I don't think I could fit 5 tubes of 9mm... I know 4 would work well for 9mm and .40 and just about any like sized cases.. I'd have to go with 3 tubes for any case diameters over .50".

Perhaps I should just take a list of all the calibers the 550b supports and see which I can make fit into tubes for the feeder?

Edit: AFter looking through my LEE reloading book, it looks as though this could support every caliber that the Dillon supports... It would just need two different tube setups... one for cases under .5" in diameter, and one for .5 and over (mainly magnum loads, from what I can tell).
