Mykeal, thanks for the measurements. I guess going by sight and feel I was pretty close. Your measurements say that #11 CCI and #11 rem is the same. Perhaps the rem seems larger because of the thickness of the cap material, and its ability to expand easier? Are the #11 rems split like #10s? That could be it also. Haven't used #11 rems in a long time.
And of course different lots of the same size don't match up.
