Difficulty Retracting Bolt

Hi All,

I recently purchased a Remy 700 in .300 Win Mag (used). Inspected it, Cleaned it thoroughly, mounted a scope and hit the range with factory ammo. After firing, the bolt will lift normally (easily) but the bolt won't retract. I have to beat on the bolt handle with the palm of my hand to extract the fired case. I did not see any obvious marks on the brass however the primer appeared very slightly flattened. I checked the bolt and could not find any marks. Rifle shot under an inch with the factory ammo so i am pleased about that but the stuck bolt really bothers me. Any suggestions would greatly be appreciated.

I'd suggest you check the head space with go no/go gauges and rule out excessive head spacing.

Re: Difficulty Retracting Bolt

Does the bolt handle lift with little resistance and then not draw straight back on fired case?


look at the gap between the bolt handle and the bolt handle cut out in the reciever. If the handle is closer to the back end of the reciever cut out, then you may be lacking primary extraction.

Normally we want the bolt handle as far forward in the cut out as possible with maybe a .005-.010 gap the bigger the gap the less the bolt handle and reciever cam contact is made. The cam causes the leverage to "pop" the case lose from the chamber.

If that is the problem I would have a ptg handle tigged on and timed for maximum extraction.

Re: Difficulty Retracting Bolt

Thanks for responding. I took the rifle to a local smith who is going to clean, gauge and bore scope it to try and identify the problem. The bolt lifts normally ( easily) then won't retract unless force is applied. I'll let you know what the smith finds if anything. I'm hoping he finds something silly that I overlooked like a base or action screw contacting the bolt but that might be wishful thinking. Thank goodness Kirby is finishing up a 300 WSM for me soon.

Thanks again....if you can think of anything alse please let me know

Re: Difficulty Retracting Bolt

I looked at a used Rem the other day to see if I could find a downer and I found one that looked good till I checked how much contact it was getting on the primary extraction cam and there was zippo, bolt was touching at the back also so I pulled it and you could see where someone got over zealous with the lug lapping, you could see the taper in the back of the lugs! If some is good more is better kinda deal, I passed on that one!!

Re: Difficulty Retracting Bolt

Hi all, Heard back from the Smith. Bad news. The chamber had several issues that were bad enough that a re-barrel is needed. Buyer beware. LOL. On to up side a 26 inch stainless Hart match grade barrel and having the action tried up will be a good thing. Thanks again for the responses
