Rifle bolt jamming in wet conditions

Will do
Do you mean to a level to which the grease is essentially sealing from any water ingress rather than simply lubricating?
No, I don't think you'll stop the water getting in. I'm just wondering what is stopping the bolt from moving easily. Can you see wear in specific places on the bolt where it might be galling?
 
Have you tried different ammunition? To see if that is jamming- I was using some old Sako ammunition in my Mauser- had to polish the ammo and it stopped jamming . There was a protective film over the ammunition.

Ye I use a variety of ammo from at least 4 manufacturers
 
There is no wear on the bolt
Especially not anything that is falling
I use "white gun grease" not lots but a small dab over my bolts, also use it on the mod thread, chokes in the Browning's
A small pipe brush a flash of gt 85 to clean the action let it dry and try the grease is not a big out lay for a fix,

I am not familiar with this rifle but I note that it has a three position safety catch - similar to my Mannlicher (though it is a roller). One of the safety positions locks the bolt down whilst the other still enables bolt lift; the final one is safety off. I know when I first started using the rifle I had a few…. Err….mishaps when I forgot about the additional safety setting and occasionally was not “positive” enough in rolling the safety forward soooo in the spirit of helpfulness perhaps try the safety a few times without a live round and see if there may be an “interim” position where the lockdown function isn’t quite off. If the bolt lifts cleanly but doesn’t pull back then it must be something else….
Good luck - very frustrating!

It may be some form of hydraulic lock with water getting into bolt lugs etc. It may that its getting cold as well.

Firstly I would the rifle a really good clean with a good degreaser and get all the gunk out. Powder residue mixed with grease gums everything thing.

Then sparingly apply a light gun oil or possibly a dry lubricant to bolt and action. And a small (1mm diameter) blob of good gun grease to the back of the bolt lugs.

I would also consider using some form of cover / slip that goes over the rifle whilst its being carried. The Americans in hunting videos in Alaska etc all seem to use a neoprene cover that goes over the whole rifle keeping the optics / action etc all dry, but they slip off quickly and silently like a neoprene scope cover.

Whilst rifles and scopes may be water resistant / proof, I still its better to keep water off as a first line of defence.

Thanks I'll try this
I think your right on the cover, I might make something small to cover the extraction port that can be pulled out the way when ready to fire
 
It's as if the tolerance between the bolt and the receiver are so close that water ingress causes a jam.

I think that this is the root of your problem. Try grease on the bolt and this will confirm it.

If it is then you can improve things by putting some fine lapping paste on the bolt body (keep it away from the bolt lugs lug abutments - you don't want to change headspacing) and working the bolt repeatedly to smoothen it up and increase clearances.
 
Take it back to the RFD you purchased it from and make clear you do not want it back until the issue is satisfactorily addressed by the Manufacturer. Sounds to me it's simply not fit for purpose as an all-weather working rifle.

Hope I'm wrong.
