I just got a new mini and it sometimes will eject ammo and chamber another one. Other times the ammo will jam or not eject the old casing at all. I have done the field strip they have on the ruger website and cleaned and oiled the gun. I have fired about 200 rounds and tryed diffrent kinds of bass cased ammo. What do I need to do next.
Thanks
Erik

Are you shooting reloaded ammo or is it all commercial? If it's surplus, where is it from? Have you verified the extractor is pivoting correctly and that the ejector/slide stop is properly installed and moving?

Look at your magazines as well. Are they Ruger or 3rd party? Does the problem present with all of them or just with some?

Edit: Also, since you field stripped... Is the recoil spring guide rod properly inserted (flange toward the barrel/top of the weapon, not the bottom side).

Could possibly be your gas port bushing? I had that problem when the hole diameter was too large. The bolt was trying to extract the shell while pressures were still high, brass was still expanded against the chamber walls.
Do the shells extract from the chamber easily after?

They come out very easy after they dont eject. And about 50 % of the time the come out just fine sometimes the jam though also

Erik, You indicated this is a "new" rifle. Did you mean new to you, or literally new? If it is truly a new rifle, you need to approach Ruger about this. They have excellent customer service...;)

First off, more info is needed. Is this a brand new gun, or new to you? What series/model is the gun?

Sounds like the same problems I have. I replaced the extractor, and that only slowed the jams down. Did not solve them. My mistake was not just sending the gun back to Ruger in the first place.

Here is a thread I started on my Mini-14 about my jamming problem. It is several pages long with lots of photos. It may help you understand your problem. If your problem is the same as mine, I would suggest you just return the gun to Ruger, and let them fix it.

Sounds like short stroking to me. What happens is the bolt does not cycle far enough or firmly enough for the ejector to whack the case head and the case is driven back into the chamber. Weak ammo, insufficient gas, or heavy grease for lubrication can cause this. Mini usually apply way more gas than necessary so I'm wondering if you have an obstruction in your gas block. Or maybe your op-rod is dragging in the stock. Here's a test to see if something is dragging. Remove the op rod spring and install the rifle into the stock without the trigger group. Tilt the muzzle up and down at maybe 45-degree angles. The op rod should slide freely without dragging.

Could also be a damaged or broken ejector/bolt hold-open "finger". Does it show any signs of damage? It should be long enough to fill the slot in the bolt. If it's short the tip may have broken off. Not that I know this to be a common defect, just thinking of things that could cause erratic ejection.

When your rifle DOES eject do the empty cases kind of dribble out nearby, or are they thrown with gusto 20 feet away?

My new Mini did the same. The link that Wingspar noted is GREAT.
I cleaned mine once and it still acted up. The second time I cleaned it REAL WELL and payed extra attention to the chamber area where the cartridge sits, that has solved it so far.

Lateck,

Thanks for all the help, I am sending the gun into ruger after talking to ruger and taking the gun into a local gun shop.

I too have had this issue. I have sent in the Mini 14 582 in twice now and the gun smith I bought it from claims it's fixed due to a burr on the bolt. Hopefully I'll be able to test fire it soon. Mine would only start to not fully extract till 30 or more rounds were put thru it. No matter the ammo or who it was from. I'm in upstate NY so ten rounds mags is all I'm allowed. It doesn't seem to matter which mag I use. I'm assuming the failure is due something expanding and causing drag or a short stroke. And it leaves a wonderful gouge on the case where the extractor and bolt meet the case. So the brass is useless for reloading now. About 1500 rounds at most put through it. I'm wondering if the gas bushing is burnt out. I've cleaned it but this is my first Mini 14 since pistol grips are a no no in NYS

Had the same problem with my 582 Tactical. After the third time back Ruger replaced the rifle.
