Tikka 6 creed PVA 108eldm feeding issue

[lintond]

I have the same PVA barrel and after a box I was having issues with closing the bolt. Had a carbon ring at the start of the freebore.

Is there any marks on the bullet? Mine had an obvious ring around it where it was getting stuck.

I haven’t shot mine after cleaning but it’s feeding again.

Get the stuck case out and look for scratches or marring in some place it shouldn't be like on the bullet or on the neck/shoulder/case body. I'd clean your chamber and throat and see if you get any heavy fouling or brass shards. Since it is a PVA barrel, did you install it? If you did, take the barrel off and look at the chamber to visually inspect it.

does marring on the bullet after cycling through the action indicate something negative? I noticed this when checking to see how mine cycled after installing my prefit. its shooting and cycling fine but not sure that a big deal

Not really. All my dummy rounds look like this. As the bolt moves to battery there’s slot of pressure with the plunger both going in and out of the action.

If it were doing it with the ejection plunger removed maybe. But still, this is Rokslide where nobody cleans, there’s gona be some carbon in there.

Those marks look fairly normal as I don't see anything that indicates a hard stop into the lands nor an unchamfered edge that is peeling brass or jacket material off. I've had factory ammo that the bullet stuck in the barrel due to a short chamber. I've also had to use emory cloth to break the edges on a rifle that was shaving brass off to a point I wouldn't even attempt to reload it. Sometimes you wonder if there is ever any QC done before things leave the manufacturer.

The marks are not normal in my experience, unless you have carbon ring or have under gauge freebore/tight throat. It could be feeding at poor angle, and the bullet is catching one a side of throat as it's releasing from feed lips into battery, or scraping against the feed ramp up into chamber. But if those marks are around the majority of the bullet diameter, you liky have chamber issues. If you're not cleaning the barrel, it's probably carbon. This no cleaning trend might work for some here, but I tried it on a 6cm and 22gt, and it didn't work for me. I kept having to pull powder from 150-350 round count after having a good shooting load at stabilized velocity.

I wondered if some had the short freebore pva chamber but that wouldn’t cause a round to be stuck or more than land width marks on bullets as far as I can figure..

@Bc45 did you check head space with a no-go gauge?

It's just one side of the bullet after one box of ammo. I do plan on cleaning it at least after this initial box when I get my stock back and swap everything around

Seems like maybe just a sharp edge somewhere that it's running over while being chambered?

Yes I checked it and it was just fine. Just did check a couple days ago and fine again

Yeah I put it on. I’ll take the barrel off later and see if I come across anything weird. Thanks

Did you get the barrel off? Did you find anything limiting travel?

No I have not yet. I switched to a couple different boxes of ammo and had no issue with it feeding so I think it was just a bad case or 2 of Hornady. I’m going to message them to see what they say. If it happens again then I’ll take it off

I have 45 rounds through it and it cycled and shot flawlessly. Took it out of my rokstock to have some changes done to the stock and thrown it in a krg. It cycled pretty badly... Put it in a stockys VG and same thing.

First things first, have you put it back into the Rokstock to see if is still works in that one? From your discussion, everything as fine until you took it out, and you didn't say if the problem persisted once back in.

Yeah I’m keeping the “bad” lot of ammo and when I get my Rokstock back I’ll try it out again. Seems weird it would just be that but everything did change when I took it off. It’s getting redone so I have to wait a little.

I may have missed it but have you checked the dimensions of the stuck case with a caliper?

No I have not. I’ll actually give that a go and see if anything stands out
