Guys is there such a thing as a standard size base for the .223. I have an RCBS mold and the base is 0.216
I called Lyman today and theirs is 0.218 I am trying to find gas checks that fit and thus far have not succeeded. One gentleman here suggested chamfering the base but that does not work. Any ideas??

There is a sticky post in the gas check subforum with an index of sizes.
