OK, one or two sentences from your post support what I've said from the beginning
But I have been pushed to show proof, after proof of my OP
I give the references and get bitch slapped each time
Guess I should have just stayed out of it

Sorry...This is one of those where the nuance of voice is lost in the forum.  I asked to see the scan not because I didn't believe you or wanted proof, but because I don't own the book but am escalating the need for a retraction with the publisher.

It was "I'm gonna need a scan of that [so I can take it up with the publisher!]", not "I'm gonna need a scan of that [cause I think you are wrong and can't read, prove it]".

My apologies about any offense.  I certainly meant none.

And, I would add, you comments have added a lot of value and worthwhile information to this thread.  The chamber/reamer drawings are a great reference.

Thank you for that Sqlbullet
I have been doing some searches to find if (and when) SAAMI may have adopted the 5.56 NATO dimensions to help standardize the Round
So far, I have come-up empty
I do find it interesting that in all of the UTube Vids I have watched on this, all show that (factory) .223s LOA being as much as 0.010+/- shorter
than a factory 5.56 NATO

I fight the same fight when it comes to the .308 vs. 7.62 NATO argument
I guess; anytime you take a Military Round and intagrate it into the Sporting World (or visa versa) you carry along the same issues
So tell me again how Trump will be worse then the last 8 years !

yeah.

One big issue in the 308 v 7.62 fight is the CUP v PSI issue.  Before piezo electric transducers all CUP ratings were referred to in PSI units, although there weren't PSI.  Once transducers came out and we had actual PSI readings, there were different than CUP.

But, the US Government just left PSI in the docs for 7.62...50,000 PSI.  It is really 50,000 CUP, and measured rounds on transducers come in around 61,500 PSI, same as 308.

But you get a lot of guys that are certain 7.62 is 50,000 PSI and somehow magically they get 308 external ballistics with 20% less pressure.

I never updated this thread...

I found a used Mossberg MVP Predator and snatched it up... I was a lil skeptical so I hit the range the same afternoon...











 I did not need to worry and I am thrilled with my new (to me) rifle!!
