2015 SAVAGE Model 10 feeding/chambering issue

Bolt cycles fine without ammo Dave.
Bolt chambers the round easily, but a problem exists if I attempt to extract an unfired cartridge... I find it odd. That very same cartridge once fired extracts without issue or resistance... figure that one out.... I cant...but tomorrow....

I'm going to the range tomorrow. The more I think about this the more it bothers my sense of perfection. I will fill all Y'all in tomorra...

I am considering the acquisition of the gauges and the wrench...
If the barrel was in fact made with a short head space or with a worn/damaged reamer.... what is my solution? A new barrel ? or a modification via some machining?

a fired case before neck sizing measured 2.006 +/- 0.0015 I trimmed everything to 2.0035 +/- 0.0015. I will see how this works when the time comes.

Headspace only - If it is a standard Savage barrel nut system, and you have no sights on the barrel, all you have to do is back off the barrel nut, and then adjust the amount the barrel is screwed into the action, so the Go gauge just fits. The first step of course would be just to try the Go gauge to see if it fits.

If it is the chamber that is short, then it needs to be reamed with the correct reamer. Savage may just replace the barrel.
 
geez, okay.

catch 22.... I could twist up a set on the lathe by the time a go no go set got here. but I dont have the proper dimensions. I could also fab myself a barrel lug wrench too...
Woufd'nt be the first time I have had to make specialty tools.

heading out to the range shortly.. its a balmy - 7C in Courtenay area... fun day ahead!!

I think "painting" up a loaded factory cartridge that is giving you extraction problems with a black felt marker is the first thing to do. It should tell the story of where the cartridge is binding up. Of course it could be the bolt, but since it extracts fired cartridges, I'm having a hard time finding a way to blame it on the bolt...
 
EMPTY rifle, close bolt and slide the rear baffle back against the bolt handle.
Insert PAL or credit card etc between the action and the rear baffle opposite of the bolt handle and try to open bolt without forcing. The handle should NOT lift.
Try again with a .012" - .015" shim or thinner object such as three or four layers of printer paper. Bolt will likely now lift without forcing.

AT THE RANGE try the thinner shim [or layers of paper] with the ammo.

0000 steel wool will polish a bullet nicely and any contact will show. This can be repeated.

If you get the results you want pm me for info as I may not read this thread again
 
Gentlemen,
Thank you all for your inputs, suggestions and thoughts.
I am perplexed. very much so and I will tell you why:

The day I reported this issue to you all I mentioned that the rifle would load but not extract the loaded live round with out undue force... The cartridge could be fired and then extracted without issue.

Yesteday I trekked back up to the range and I discharged 50 rounds without issue. I bought 20 new FC 180gr SP's and brought a handful of modest handloads.. 42.2 gr Bl-C(2) 180 gr hrndy SST's and cci regular primers.

Images below indicate what I have.
Some general info on what's passed through my hands:
the jamming cartridge came out of a box of Win sprX . 150gr SP. Once fired, the cartrige ejected with out issue. but would not eject will still "live"
oal of cartrige before trimming and chamfer : 2.008 -2.010 max. reduced to: 2.0035 +/- 0.002 and then reloaded as above.
The new Federal ammunition i took with me cycled without issue. The reloaded ammo, like wise. ???
The Federal OAL after discharge is 2.008 to 2.011 !

I have no idea what is going on... The only anomale is the bullet... and well thats long gone and unretreivable... Lesson learned.... : if it happens again check the bullet for landing marks.
The bolt was very difficult to pull back. A rubber mallet would have made the task much easier. The force used to close the bolt was normal reloading force.
Does any of this make sense?

Also upon discharge the neck expands from .334 to around 0.3435 to 0.344 and this is consistent. Where is that difference coming from if the chamber is the fixed dimension to which the cartrige expands to after dispatch? Or is this merely caused by spring back and varying thickness in the necks of the cartridges?

Is the amount of blow back around the neck normal ? My .223 Does not produces the same sorts of markings.. I notice that this patern is not uniform about the perimeter of the neck.

The cartridge side shots below: same cartridge rolled 90 degrees.

Cheers!
