All of a sudden bolt won't close??

[mattri]

This is probably something dumb but I am stumped.

110 in 300BO put it together a few months ago have had no issues at all.

Have prob 500 rounds through the rifle, some factory, mostly various handloads all fired without incident.

Had the rifle at the range yesterday- shot great, no issues.

Today took barreled action out of the stock, tried cycling the action and the bolt wouldn't close.

Bolt out of action- Pull trigger, depress BO button and bolt slides right in, no problem.

Try to close bolt and it hangs up- like there is something in the way.

Bolt will slide home and handle will drop to about halfway and then it binds up.

Force will close the bolt with a "cam over" feel.

Have completely stripped the bolt, inspected and cleaned the breach/bolt face area over and over, have chambered empty cases and dummy rounds-
Absolutely no idea what is causing the bolt to hang up??

This was not an issue yesterday, and now all of a sudden the bolt doesn't want to close without excesive force?

Thoughts?

Sounds like something foreign got in there and is causing the binding. My guess would be something between the lug ramps and breech face of the barrel.

[mattri]

Agreed- have cleaned everything 100x over and still getting the binding.

There is literally nothing in that chamber- hence the question..

So, on an empty chamber, it binds but closes with a cam over feeling? Or ONLY with a dummy round or empty case? If it’s doing this with an empty case, it’s that case. Like mine, I bet you have really tight headspace. Many of my resized cases won’t chamber without that cam over force.

loosen back screw on front scope base and see if problem goes away

[mattri]

Yes it binds on an empty chamber.
Scope and base have been removed, barrelled action is out of the stock.
