Move the front sight ~.135" left. If you run out of dovetail, check bedding and barrel timing.

[John Sukey]

Might also want to check if the fore end is bearing on one side of the barrel.

barrel timing.

okay, now you have me, and completely i might add

[Parashooter]

Barrel timing means how far the barrel is screwed into the receiver. If it's off, the front sight assembly may be tilted rather than centered .

[Fred]

Isn't that where the two marks come in that should be aligned on the side of the barrel and receiver?

[Parashooter]

Assuming the marks are in the right places. Maybe so, maybe not.

Milsurp from a reliable milsurp dealer(Century is not), bubba'd or rebuilt bubba'd rifle?
30" left at 200 is a lot. You won't be able to adjust the front sight that much. Assuming the front sight is centered and not bent or otherwise damaged, itself.
I'd start by bore sighting it. No pricey tools required. Take out the bolt, put the rifle on a flat surface, sight on some object about 100 yards away, then look through the barrel. If they don't match, and I'm guessing they won't, the sights and barrel are off. Next, take the stock off and put a straight edge on it. Looking for a bent barrel. Possible, but not likely. Then look at the indexing. Put the rifle, without the stock, in a padded vise. Use a 6" level on the charger guide to get the rifle level, then put the level on the flat part of the chamber or on the front sight wings. That'll tell you if the barrel is canted and, therefore, not installed properly.
"...Move the front sight ~.135" left...." Absolutely not. Front sights get adjusted in the opposite direction you want the group to go.
Headspace OK? Nothing to do with the sighting, but check that first if you haven't already.

I think he's saying it's hitting 30" left (". . . with a 6 oclock hold it hits that far left"). I imagine he'd like the group to go right. As you indicate, that will require moving the front sight in the opposite direction - left.

[Sunray]

"...think he's saying it's hitting 30" left..." DOH! When I pay attention, I don't say silly(stupid, really) things like that. My apologies.
How do you figure ~.135"? Doubt that'd move the group 30" at 200.
