Anschutz Gurus -- Need Your Help

I have a strange phenomenon on my Anschutz 64 MPR -- seems as though the bolt won't stay cocked when it's placed back into battery and despite changing the sear adjustment screw backwards and forwards it only intermittently engages the sear properly and keeps the bolt cocked.

Little bit of background -- I've had this rifle for about 9 months and would say it's shot around 8,000 rounds. No problem whatsoever. I did replace the action spring with a J and P set to get a quicker lock time and it worked fine for about 600 rounds. I even took that back out and replaced it back with the original striker spring set thinking that may make a difference, but to no avail.

Also, the safety won't engage either, however when I play around with the safety, it sometimes cocks the bolt properly. I'm at a loss as to what's the culprit. I've played around with 64 actions adjusting the trigger spring and sear engagement for the past 18 months and have not had this type of problem before. I've checked inside the action to ensure no foreign object is obstructing the sear but nothing looks like it's in the way. I've re-read the Anschutz manual on this particular action and it does appear I'm doing everything properly but perhaps there's something simple I'm overlooking.

Any suggestions? Again, I've tightened the sear all the way down to a single stage, tried to fire it but the bolt wouldn't stay back, then backed it all the way out again and same thing. Short of sending it to a gunsmith who specializes in Anschutz's, I thought I'd check here first. Any suggestions??
 
Well, you might have had something as simple as crud in it but since you've been cranking on the sear screw it's probably gunsmith time. When it comes back I would'nt touch the sear engagement.
 
Had a similar problem check the cam surfaces on the bolt body and the cocking piece. I had problems with the blued version with wear. had to refit the notch the chromed seem to wear better
 
XRinger --

Is this something you performed yourself and if so, what website did you go to to get the information on how to do it? I don't know of a qualified Anschutz gunsmith in Charlotte, NC so would probably have to send it away for repair if I can't do it myself. Was hoping that it was something I could attempt on my own...
 
I'm thinking that if it works intermittently it's probably a well placed particle in the trigger. Use lighter fluid and compressed air or pressurized carb cleaner on the trigger. Then, play around with the sear engagement.

Clean the chamber as well as the area where the rim contacts the barrel. I don't entirely understand the mechanism involved but had a SAKO that would go similarly screwy when the chamber was dirty.
 
Housing of trigger original?

Could be short of a washer on the rear of the trigger housing between house and action.. Make sure you have the housing at a place where You don't see the protruding tip move when you put down the bolt handle.If it is the old kind of trigger, check for washers too. :)
 
I now see what the problem is -- the catch link isn't 're-setting' the sear to engage the release latch. If I manually move the catch link back, it'll sit properly and allow the bolt to stay cocked. Once it's released the catch link isn't being moved back far enough to engage the catch link. There's no obstruction present that I can see (cleaned it up with some CLP scrubber) but for some reason the catch link isn't being reset.

I've looked at the trigger diagram in detail to see whether a spring popped loose but can't see anything missing. When you look at the way the sear works, it looks like the release plunger isn't being moved by the bolt back far enough for the sear to engage. Based on the diagram (item #57 - spring) I can't tell whether it's somehow been sheared off or broke. I feel like I'm so close to diagnosing this!!!

Update: I found out what happened -- one of the springs (Item #57) broke off which was causing the catch link to not move back properly. I'm going to call Neal guns to see if I can order a replacement.

Kurly,
I have a 54annie and had problems. I found I could move the trigger ass.
back A bit this allows more spring tension. Also started putting A
bit of lighter fluid on bolt and trigger. they fixed my problem.
