Okay I have a T/C Venture action w/ a Kriger barrel.. My problem is that the bolt will not close with 175g factory ammo. I've only put 60 rounds thru the rifle all 168fgmm. Two weeks ago I went to fla to do some shooting with my father and loaded a 175g round and it was kinda stiff trying to close the bolt so I tried to open the bolt and extract the round.. the bolt wouldn't open so after about 20 mins of trying to get the bolt open I deside to fire the round down range and continue to try and open the bolt well after about 45 mins of tapping I get the bolt open and notice my extractor is broke.. I didn't think much of it because extractors do break so I sent the bolt back to T/C and today it came back in with a new extractor.. So of course like anyone would I chamber a fgmm 175g round and the bolt will not go forward all the way and it takes a snug pull to get it open so I try another round thinking maybe that one is fucked up and still a no go. I also try with a USA AMMO 175g round w/ LC brass same issue.. I try a fgmm 168 and a usa ammo 168 and the bolt is flawless.. WTF is the reason for this?

Re: Big problems.
Did you leave part of a fired case neck in the chamber? If the neck separates and stays in the throat, you will not be able to chamber a successive round. Look hard inside that chamber.

Re: Big problems.
First off, not busting your balls so here goes
1. If it don't fit, don't force it. If it initially was tight and your jacked the extractor up, so be it. Don't force anything......period.
2. It is a custom build with a custom barrel.....ie; dare say its probably got a chamber that is on the tighter side, unlike the Savage you recently had.
3. Seriously doubt the 'smith is at fault!
4. Again, if it don't fit the first time.....lay off the "gorilla torque". Chances are if it didn't work once, damn sure bet it probably ain't gonna work twice.

Re: Big problems.
The barrel throat may not be long enough for the 175's? Seems like they would have put a SAAMI chamber In it that "should" allow for the longer round.

Re: Big problems.
Secondly, may have been chambered with a reamer (M852 I think) for the 168's. If that's the case, a 175 is gonna jam in the lands. Call the 'smith and confirm what reamer the chamber was cut with, may not be throated for the 175's.

Re: Big problems.
I'd have to disagree with w/ da' dawg somewhat, there is no way any spec chamber should reject factory 308 ammunition. I could see some out of spec rounds randomly not fit, but two different manufactures and different lots of ammo.... do dice. I'd get the chamber polished out a bit.
but as the Dawg said not smart on re-cambering the 175's
my buddies 300wm was doing the exact same thing, but more of the normal factory round would fit and hand load would not. Rounds were good to go on his old barrel and new barrel no dice.

Re: Big problems.
There isn't anything in the chamber I've looked pretty closely @ it. Second I'm not "Dumping" it on the smith I'm just asking because I don't know. I just think if the chamber was on the "tighter" side that would of been something mentioned w/ the rifle details who knows maybe I'm retarded. By any means I didn't over force the first one I just didn't pay to much attention to the bolt not riding as smooth as it does with the 168s and I didn't @ all force it this time as soon as I felt resistance once the round was 3/4 the way into the chamber I simply opened the bolt.
1:11 twist HV contour kreiger barrel < So this would be a "tight throat" barrel?

I'll do that, thanks for the info. Like I said I just don't know because the only thing I know about the rifle is what I was told but like the gentlemen said above I figure if it shoots factory 168s why wouldn't it shoot factory 175s?

Either way it's extremely frustrating you would think someone would put that information about a barrel being throated for a specific round under the details. things like this would of been more than a deal breaker for me. anyways I emailed the original owner and the smith so only time will tell.

Re: Big problems.
Stop freaking out, it's not a big deal. Sounds like the throat was reamed for the 168's on purpose. This is way better than a saami spec chamber and leads to more accuracy potential. If you want to shoot the 175's or 190's, get the throat reamed out longer. There's nothing "wrong" with your rifle, just right. It is a custom chambered rifle and you should expect it to be cut for a certain load.

Re: Big problems.
DUB, I should have a .30 cal throating reamer in the next couple of weeks. Next time you come down to your Dads shoot me a PM and we can lengthen the throat for the 175's if you still want to play with them.

Re: Big problems.
FGMM with 175s is a "normal" length round that should fit in any SAAMI chamber. So, you'll need to figure out just what type of chamber you have. At a minimum, throw a 308WIN Go Gauge in and make sure it fits no problem. Next, I'd find a buddy who reloads and can check a few measurements for you. Assuming the Go Gauge fits, you should check your base-to-ogive to better understand how short the throat is cut.
Good manners and safety dictate any non-SAAMI chamber be called out. Shame on the original owner if he did not do that.

Re: Big problems.
I have to differ with Scooter-PIE...a custom chamber may have normal OAL for 168 grains of what-ever...but as Law-Dawg says...the ogive may be different enough so that the same OAL with the particular 175's jams too hard. Been there, done that. I have a rifle that is supposed to be cut for 175's...but it loves 186 Scenars...is that the original owner's fault? I guess he should have told me that. Probably, he never shot anything else than what he spec'd it for. Never gave it a thought, is my opinion. FWIW.

Re: Big problems.
I've gotta remember the don't force thing. I've been running some 150g surplus ball ammo through my Remmy, and it's been kinda sticky and tough on the bolt. I'm not gonna force the bolt on sticky rounds anymore.
