Bolt catching at top of cam over

[jsthntn247]

Just got my gun back from being rebarreled. It's a remington e series long action. It's been trued and a cut rifled barrel put on. Without the trigger on the bolt slides in the action and cams into battery without a catch at the top of the down stroke. However, when I put the trigger on the catch starts and does it every time. I run the bolt into the action, start to turn the handle down and it will move a few thousandths then there is a catch, I can keep pressing down and it will go all the way down as normal. I have checked the bolt nose, back and front of the lugs, and every where else looking for galling but can't see any. I did a barrel break in and short load development and it shoots in the .3's already so it's not effecting accuracy it seems. I have tried 3 different triggers and it does it on all of them. Any ideas? The catch is bad enough that I can't cycle the gun quickly and this is a hunting gun so I'd like to get it fixed.

its been trued to the point its out of time

That's what I was thinking. Maybe the caming surfaces wern't lining up correctly. Looks like it will head to Alaska.

Timing helps when opening the bolt, not much to do with closing it though !!!!

Realizing that it closes without a hitch w/o a trigger and catches with one I would still check the front action screw and see if it is protruding into the breech area enough to just touch the bottom lug. Perhaps cocking the striker tips the bolt a tad up and forward enough to make the difference.

 

[jsthntn247]

Just checked and the screw is not sticking up in the lug area. It's opens fine without a hitch.

What do you mean by a catch ? Could it be just the cocking piece and spring being Held compressed by the sear ?

^^^This...^^^^If so, you have a common trigger timing issue. Not a big deal, and is one difference between most custom actions and using a factory action for a build. It can be helped or fixed but most live with it.


So, is it possibly just where the trigger is picking up the cocking piece, that you are feeling upon closing, or something else? Very few, if any factory actions time well, particularly with the newer Jewell triggers.


If you want butter smooth closing, a timed custom action and trigger are the way to go.--Mike Ezell

I just shot it a few times. It shoots extremely well and the issue is not catastrophic if nothing is galling or binding. Would sending the handle off to be timed effect anything. This was the last 5 shots.

The fact that it only has the problem with a trigger installed indicates some problem with cocking the firing pin or with the cocking sear making contact with the bolt body. Remove the firing pin from the bolt and see if the problem is still there. If the problem is there with the firing pin removed then the cocking sear is too high. If it is only there with the firing pin installed, then the problem is related to the firing pin. Once you have narrowed it down, you should be able to figure out what to do to fix it.

With the chamber EMPTY , hold the trigger back while closing the bolt , any difference ? Please let me know .
Thanks

Yes, if I close the bolt while holding the trigger it does not do it.

Then what you are feeling has nothing to do with the bolt handle...which is relative to primary EXTRACTION issues, not closing. I don't have it in my hands, but it sounds like you are feeling the firing pin being handed off to the trigger. The trigger being too far rearward, it adds to the cocking length. You could also say that the cocking piece on the fp is too far forward. Timing this relationship for proper fp fall and handoff without unnecessary cocking is what trigger timing is all about.

 

[jsthntn247]

Thanks Mike sounds like that is my issue. Who can fix it? Load development is done so I won't be shooting this gun for a while, no better time to get it fixed than now.

 

[jonbearman]

I would think Mike Ezell ought to fix it. Or send it back to whom did the work in the first place and preacher can and will fix it.

Its a timing problem, just dont know how a rebarrel job could have changed it.
Unless there is a trigger hanger that was removed and
replaced backwards?

If it does not happen when the trigger is pulled , besides of what was already said , may I be so bold as to ask are you accustomed to angle sear triggers ?
When they are cocked , they push the bolt body to the top of the receiver . Have tou changed the scope base ? Bolt shroud ? Firing pin or spring ?
When the receiver was trued , how much was removed from the receiver locking lugs , if the bolt handle needed to be relocated you had a bit removed .
You would also need to know how much was removed from the bolt lugs .
If you had a longer than necessary rear base screw ( originally ) it could have helped keep your bolt lower in the receiver , which may or may not have altered how you feel the cocking piece being held by the sear.
Good luck , Gary

Could the catch at the top of the downstroke be associated with the firing pin spring binding in the bolt body. I'm wondering if this might have been a j-lock action where the opt shroud was replaced but not the firing pin and spring. How could I tell this?

 

[jsthntn247]

I put marker on top of the trigger and cycled the bolt several times. This is where it is rubbing. Is this common?

Looks normal, if you were dry firing or letting the firing pin down.
