based on my research the barrels are reamed at .300 and then the rifleing (grooves) are cut to a dimension cross groove of .308 so the raised (smaller id) is still at .300 and the cut (larger id) is .308? wich is backed up by

and the specs for the bullet says .309 - .003 sounds like i need to look deeper into what the optimum groove "height" is for bullet stability and spin

Many gunsmiths have no experience with Garands. I would suggest getting a MW, TE gauge. StandardParts LLC sells gauges.

CMP customer service will take care of you. Like Orlando stated they are real busy.
I also use the springs from Orion7

Op rod springs: not good, replace (customer service, probably). front sight: needs to be re-centered (come close -- you're be swinging the rear sight around anyway) and lock that screw down. Bore: take a bullet, put it down the muzzle. If it drops all the way through, you (it) has a problem. If it only goes down a quater inch or so, it's "probably" no big deal. The bullets measure 0.308 inch and the big picture is the bore engages the bullet. If it doesn't drop through it's catching rifling on the way though. At least that's the huge picture.

Use a loaded round, I am starting to think you may be finding problems that dont exist.
Move the front sight back some and adjust rear windage

Ok..again i apreciate the input..as i mentioned in initial post. When i picked up from CMP. Rear windage was all the way left. I cleaned n recentered. Took out shooting and again to git center at 50 yards was rear windage sll the way to the left. two weekends ago i took it back out. Centered rear so i could adjust front ( as some had said may not need to be as excessive)... Result to center at 50 yards is in pics. this is why im perplexed. Still waiting paitently for Customer Service to email me back but sounding off to more knowledgeable folks than i to throw ideas. again i appreciate all input..

Looks good to me...a 2. From the lighting the crown looks a bit beat up.
