Rifle Jamming on Golden Tiger Ammo. Every Shot

[Tricolor]

From reading his problem, I don't think it was a bad batch of ammo, but his chamber that needed a good cleaning. GT is great ammo, I have excellent accuracy results with it.

I was under the impression he tryed the other ammo after the GT without any cleaning, or changes and had no problem. At least there is no mention of any changes.

He then cleaned his chamber and now we are unsure.

Just for clarification, I did try the SB immediately after the GT in the rifle while the barrel was still hot to the touch and without any cleaning whatsoever, and it worked fine. And in response to someone's opinion that the nylon brush does nothing, just in case, I jammed a .45 cal brass bristled bore brush into the chamber and worked it around and rotated it which helped get even more crap out, so if the nylon didn't do anything, that sure did. Anyways, I'm FINALLY getting out to the range tomorrow to test the rifle after the cleaning, so cross your fingers, wish me luck, and even pray for me if you want, I'll take anything I can get to have this problem resolved. Again, thanks for all of the helpful input.

Alas, I went to the range today and it had the same problem with GT as before. I also tried Golden Bear, which ran fine, as well as Winchester 'white box' target FMJs, which performed even worse then the GT. After that confusing outcome with different ammunition choices, I just turned it in to the on-site gunsmith to have him take a look at it. As soon as he diagnoses the problem, I'll let y'all know what it is so that anyone else with the same problem could come to this thread for a solution.

I'm going to be very interested in how this works out; I use GT when I'm away from home and won't have time to do the wash down needed when I'm running M67, my preferred round.  Never had a problem with it so I'm really curious as to what's going on with OP's situation.

+1  That's two of us. This one is a head scratch.

The winchester jammed too?

I'd insect your gas port, gas valve, your extractor, extractor spring, and ejector.

Another idea, if you want to clean your chamber really well is to do it while the rifle is hot at the range so any residue in there will be soft.

But why did in his trials the Silver Bear and now Golden Bear all work just fine? He says he has cleaned all of above as I understand him. I'm just now wondering if he has a recoil spring problem with any ammo a bit less powerful. Just a wild guess after this. I'm at a near loss.

[mshanahan15]

I'm just as confused as the rest of you. I actually heated the chamber up with a hairdryer and a lighter on the tough spots when i cleaned it. Trust me, had I cleaned that thing any better, I'd have worn through the stainless steel. And yeah, it could be a recoil spring issue, because I do know that the Winchester White Box ammo is notorious for having lower pressures than its competitors. For example, their white box .45 ACPs won't fully cycle in my 1911, causing short-stroke induced stovepipes, FTEs, FTFs, and a whole slew of other failures. I'm holding my breath for what the gunsmith says, but hopefully it will just require some grinding down of the extractor or ejector so that I don't have to wait for parts because I have a horrible patience haha.

The stronger ammo appeared to work. On that recoil spring assembly, are you positive the squiggly end was inside of the bolt carrier? Not concerned how it was originally received. Many people here have bought guns with those put in backwards. Can cause this type of problem as can one of those worthless buffers they sell aftermarket.

[mshanahan15]

It came with it in backwards, but after watching a youtube video I happened to notice that its supposed to be the other way, so I turned it around. Long story short, ye, I'm sure that the squiggly end was inside the carrier and I also lubed it just in case.

That does eliminate that then also. Man, this one is a tough one so far.

Different metals and different coatings.

If the rifle still only jammed on GT, then perhapes he was shooting from the same lot of "bad ammo".

For confirmation purposes, the rifle did indeed jam on Winchester also? He said performed even worse, and I can only assume he means malfuntioning.

-To the OP:

-Do you have any other SKS's? If so dissasemble the recoil spring assembly and compare the springs.
-Have you looked up data to see if the malfunctioning loads were indeed lighter loads? If so, check your gas port and valve. Undergassing would cause jamming on lower powered cartridges.

It's probably easier to switch to something that works, but I couldn't live with that. I've had a ruger 10/22 that I've had for 5 years. It jammed 3/10 times on everything except for CCI's and hotter rounds. After 5 years I bought a $10 extractor and it hasn't jammed since.

The rifle's are pretty simple, something has to have been overlooked.

[Yugom5966]

Well forgive me for the limited data but it is late here:

Silver Bear: 2460 FPS
Goldent Tiger: 2396 FPS
Winchester: 2375 FPS

Notice anything? Sounds like your rifle is under gassed, has too strong of a recoil spring, or something is not moving freely. Maybe the extra power in the silver bear is just enough for your rifle to work.

How far was the rifle ejecting the silver bear?

[carbine85]

I'm going with a restricted gas port or the recoil spring is installed backwards.
Does everything slide and move smoothly?
