Need Web dimension on new unfired LC 5.56 Brass

[AckleymanII]

If anyone knows this dimension, it would be much appreciated.

I got a 221 FB reamer ground smaller than spec, trying to see if LC may work in the chamber.

NOTE, Lake City base diameter manufacturing tolerances are .3759 to .3709 and the SAAMI .223 base diameter manufacturing tolerances are .3759 to .3679. Meaning the .223 tolerances allow the case to be .003 smaller in diameter .3759 -.008 vs Lake City .3759 -.005.

Just using calipers on New never loaded LC '11 brass, I get .374 (one sample)
