Simple, you've got it tightened down a hair too much. Back it off just a hair or so... Is it still chambering as is?
Eventually the brass will come apart at the web, if you keep reloading it like that.
Don't know if you toss a case after X Amount of Reloads, or keep using it until the case fails.
Just back the die off a little until the ring at the case bottom ( web )isn't there.
If it doesn't chamber, take some off the mouth of the case with a trimmer and it should chamber just fine.
Not a real big problem to correct.
