Based on looking at and reading the drawings, I concur with your observation:
I was truly hard-pressed as to why you could say my numbers are wrong when yours agree with my memory and those on the drawing -- until I re-read my post and realized I had misstyped! BTW, tapering out from .2644 to .2677 and then starting a 1.5 degree slope down to bore diameter would create an interesting picture! Many thanks for calling my attention to the error. I have just corrected the typographical error.
I am still hard pressed to find a feature in the drawing that would evoke the appearance of a ring "just before where the lands start" as described in post #17.
I will concede that the observer may have confused the neck-freebore transition with where the lands start, which would explain the differences and why we don't seem to be on the same page in this discussion.
I look down about 70 barrels a day on average. I'm sorry you are confused about what would look like a ring. Let this guy shoot his barrel and see how it shoots before you worry the s*** out of him by not knowing what would look like a ring and what would not. If you don't understand that a reamer larger than the bore would remove ALL of the lands you'll need to find someone that has more time than me to explain it to you.
