You started this by saying the click was with the trigger removed. Is the click with the trigger in or out?
LA 700 bolt click-no trigger

Does not make any difference. it clicks with it trigger removed or trigger installed. Finally got another bolt.
Out of another LA that I have worked on, that is very smooth in 280AI. It also clicks in this receiver. I did notice on this receiver in question, upon inserting my receiver face truing mandrel from front that it gets tight when it goes by the tang, otherwise it has clearance, weather this has anything to do with the problem, I don't know.

I helped another guy with a click on close that is pretty common with the trigger in the action. But without your action in hand Im guessing. I copied and pasted what I told him. Let me know if this seems to describe what your seeing.
When you close the bolt the trigger engages the cocking piece in the bolt, lifting the rear of the bolt body. That lift in the rear causes the lug on the right side (lower lug after closed) to be the only lug riding the closing cams in the action. As you close the bolt, that right lug causes the front of the bolt to lift up against the action bore. As soon as the lug gets off the closing cam and on to the internal lug abutments the lifting force in the front disappears and the front of the bolt drops causing this click. Test this by holding the bolt body up while closing. If you push on top of the bolt body downward the noise will be worse. Its normal, dont worry. Why it just appeared, most likely the cerakote has worn and given you the clearance back for this to happen. It doesnt happen when you push foreward because you are overcoming the spring pressure thats holding the lugs against the closing cams.

I'm sorry Alex, I should have stated that I did get rid of the click w/o trigger. I tried Donovan's fix, but no remedy(sorry Donovan). You are absolutely right, the click is coming from the front. The action was never Cerokoted though, it is a standard blued Remington bolt. Now that(I think) we are on the same page, what is the fix? I've never run into this much of a problem before.

I just copied that from a reply I made to another guy. He wanted to know why it didnt do that when new, I figured the cerakote wore. Now to the "fix". I dont consider this a problem, but if you take a needle file and work the chamfer on the leading edge of the bottom lug (when closed) you can get the other lug to start riding the closing cam as well which will distribute the force between them. You should get rid of the click. Or ignore it, and you'll get the same result.

Thats no way to talk about your old lady!
Ok, been a little busy with some other things(problems). Yes, the whole problem(click) has been the riding up of the bolt body in the rear(bolt is/was wore there). I had beveled the bottom and top recoil lug somewhat early on in this, evidently not enough. One thing I did not mention throughout this whole thing is that there was a very pronounced drag to the bolt, to get it past the click, hence the head scratching and need to get past this problem. I did find a simple test for this situation without any modification.
First off, I clamped the front of the action in my bench woodworkers vice at the end of my bench. The wood to wood clamping of the action amplified the click, Clamping the rear of the action, did nothing(may have actually decreased the sound). Since the click was from bolt lift in the rear, I screwed in one, then two, too long of screws (6-48) into the top back of the receiver(scope mount holes) until they where just touching the bolt and slightly backed off, closing the clearance above the trigger, reducing bolt lift and.....no click. What a deal.
I greatly appreciate all the help, and suggestions I've gotten(some more than others, you know who you are). I have never had one this pronounced or problematic. At this time, the owner and I have agreed on to sleeve the bolt, front and rear, among a couple of others.
P.S. Dave Tooley: I rechambered this rifle to 300-375 Ruger. The owner, who doesn't like muzzle breaks, has shot it fireforming, with somewhat poor results, primarily the scope. Removed it from rifle to find that it rattles inside(one of a premier scope company so no cheapy). Will be sending that back too.

Glad that you were able to solve the issue. This brings to mind the saying, "If it were easy, everyone would be doing it!".
