I'm stumped...bolt won't close

Is the profile the same on the two bullets, or is there more taper on the one that chambers easily without the engraving marks? Perhaps it's an optical illusion in the photo, but the bullets look slightly different. to my old eyes. What is the diameter of the bullet just ahead of the case mouths on each bullet in the photo where the problem is occurring?

That's my vote ... a nasty carbon ring. Maybe there were a few more than 160 rounds through when you bought it.

Perhaps, but he is a guy with a good reputation on the local forum and like 20k posts with nothing but positive reviews, and he had a log book showing the rounds. So I don't suspect that to be the case, but obviously I have no way of knowing for certain.

I do know he was reloading for it and can't remember the powder, so it's possible he was using a powder more prone to carbon deposits? I don't know specifically what causes the carbon ring honestly, although I did have a carbon ring show up on my Tikka around the 500 round mark if I recall. No bullet interference or bolt issues - just crap accuracy

I've never had this particular issue. Problem is you have no idea if a custom tight reamer was used ect. In you pictures and from your description it seems the problem is the throat/freebore. I see no marks from the lands & no marks on the shoulder datum of the case.
I'd still pick up a go gauge & check but that doesn't look like the problem.

I have had a short reamed 6.5C that wouldn't close on go gauge. It was short enough that factory 130 prime ammo wouldn't close (AR barrel was Larue). My solution for that is the same I'd due in your shoes.

Clymer finish reamer off the shelf at Brownells with a few bushings cost about $200. I just turned by hand with a tap wrench & some tap magic cutting oil. Worked like a champ, gun hammers.
Just stop when you hit the shoulder and should be good to go.
If you don't have a barrel vise then pick up one of the PTG extensions from Midway & you wouldn't even need to remove the barrel.

I have a barrel vise but no action wrench for the Defiant and I have no idea how much it was tightened and would rather not mar up the gun-kote finish. Do you have any interest renting out the tools?

Just started happening with a new box of ammo? Did I read that correctly? Hornady? Compare bullet measurements, ogive location, and loaded round measurements. The rifle didn’t magically contract suddenly.

Bullet measurements are identical between this new box of loaded ammo and my box of individual bullets for reloading.

I think it just so happened to occur when I went to a new box of ammo. Minor carbon ring combined with slightly tight freebore.

Is the .17HMR really much better than .22LR for varmints?

supercorndogs
There places I can shoot 17hmr and 22lr for varmints I can't shoot 223 or 20 practical.

The point blank zero comment is spot on. Want to drive around and hit them fast. Point and shoot to 175. Ya that's a significant improvement.

Now 1 17hmr costs 4 22lr so you can walk in your shots and still save money. Who likes to miss more thought? 😂🤣😂

Would you get into 6.5 Grendel in 2024?

supercorndogs
I like my grendel ok. For me there are zero upsides vs the 6 arc though. So i wouldnt choose or suggest it as a start. I guess, "get into it" is not that defined of a term. I took it to mean if you were getting into an alternate ar15 catrdrge what woukd you choose first.

People choose to shoot the nato potato over the 6.5 creed everyday. 🙈🙉🙊I like guns.

Do you compete in any competitive, precision oriented shooting sports?

Do the rifles you compete with have a top tier barrel brand in them? A Bartlein, Krieger, Mullerworks, Brux, etc?

Do you always win or always place in the top 3?

See what I mean?

I understand your point, not sure you understand mine or maybe just don't want to.

Using a barrel from a reliably known, generally accepted as accurate, source simply removes, or minimizes, one of the biggest factors in shooting small & consistent groups.

Obviously, the ones you mentioned are the cream of the crop................usually, but there are plenty of barrels that are consistently "good" just below that pinnacle.

Such as the Douglas that the OP has, WOA, Rock Creek buttoned, & Criterion to name a few.

So if the stated goal for a given shooter is to shoot small groups consistently, ie, 10 shots, <MOA, then it surely behooves one to start with a barrel considerably better that a Radical, BCA, Stoner etc.

Yeah, you might get a winner with one of the bottom feeder barrels, but the odds are HIGHLY against it. Why go to all the other efforts involved to reach the goal with a bargain basement barrel.

It's rare that one will make the goal with a low end rifle............not that it can't happen, but the deck is stacked against it.

In the case of the OP, he doesn't have a low end barrel, not a pinnacle barrel either, but a known, generally good barrel.

YMMV
