I bought a set of the Whidden 6mm bushings for my 6BR awhile back and have noticed weird sizing problems with them. My .266 bushing is way too tight but the .267 bushing is too loose and bullets fall in the case, however the .268 bushing seems just right. I measured the inside diameter of them and found these sizes.
.264 measures .261
.265 measures .262
.266 measures .262
.267 measures .267
.268 measures .265
My Redding .266 measures .264
I'm using these with both Lapua and Norma brass.
