Not just calibers, but cartridges. How many different cartridges do you reload for? On top of that how many of each cartridge do you have a gun for that shoots/requires you to load different powders and/or bullets?
5.7x28 2 different mfgs (ar upper and ps90)

7 bolt guns, 4 levers and the rest are AR platforms with the exception of the Kriss
Now onto pistols
5.7x28 1 fn57
9mm 2 different mfgs 4.25-5"
357sig 2 different mfgs 4.4"
40s&w 2 different mfgs 4.4, 5.25"
10mm 3 different mfgs 4, 4.6, 5.25 and 6.01"
44mag DE 6 and 10"
50ae DE 6 and 10"
The DE is using the same frame, just changing out the mags and barrels
So this is very important to reload and why I do it.
