Just found this thread while researching 30 round magazine reliability problems. On 6/3/09 I purchased a factory new 580 series mini-14 and three factory 30 round magazines. All of the 30 rounders failed to function in the weapon. I experianced failures to eject, and stovepipes. Originally I thought it might be an extractor problem because the bolt wouldnt pull the empties out when using the 30 rounders. After examining the extractor and confirming it was in perfect order, I ran the rifle with 20 rounders and the rifle worked flawlessly. I have since sent my 30s back to ruger and asked them to swap them for 20s. I am currently awaiting their response. Any ideas why this might be happening????

Because they're new and need to be broken in. Also, new Mini-14 need a break in period, too. Did you try the 20s first or the 30s first?

I tried the 30's first...but it doesn't make any sense to me that they need to be broken in. Magazines should work right out of the box. Its not like I had one or two malfunctions. Not one of the 30s would work when full. That is not acceptable. I saw something on the "interesting ruger facts" stickie about 30 rounders not working in the polymer stock mini 30s...but they symptoms described were not what I experianced....I just want to swap for 20s that work.

Whoa, this 30 round factory mag problem is news to me.

Wait, "polymer stocked Mini 30?" or Mini 14? Ruger doesn't make factory 30 round mags for the Mini 30.

PMI 30 round mags function perfectly in my BC folder, which is polymer. But it's not the 580.

Does anyone know, then, of actual cases in which Ruger 30 round mags fail in the Mini 14, factory polymer stock or not?

Really? Back in the early 90s, one of my roommates bought a new Glock22 with a 15 round magazine. We could only get 9 in the first time he loaded it. It got better with each reload, until he could get all 15 in. These were GLOCK magazines with only 15 rounds.

Jim,

Forgive me if I am failing to understand you, but this was not a matter of not being able to load 30 rounds into the magazine. In fact the magazines would take 31 rounds. What apparently was happening is that when 30 rounds were loaded in the magazine, the pressure on the chamber was such that the bolt would cycle, but would not extract the empty cartridge that was left in the chamber after firing and hence, would not chamber another round.

I am a 20 year veteran LEO and firearms instructor and have conducted and received transition training on Glock, Smith and H&K semi auto handguns and have never experienced feeding problems like you described or like I have with the Ruger 30 rounders. Back in the day, manufacturers recommended firing 500 rounds before an auto was "combat ready", but to my knowledge, that is no longer necessary on modern firearms.

In my humble opinion there is no reason, given modern design and engineering, that these 30 rounders should not be combat ready out of the box. I could (sort of) understand a hiccup or two...but three magazines that all behaved identically and would not allow extraction and rechambering of rounds when loaded to capacity??? I'm sorry...that is an unacceptable margin of error. Who is to say how many rounds would have to be fired before the mags are broken in and not suceptible to similar failures in the future.

The 20 rounders worked flawlessly out of the box....and thats what I'm going with.

What I'm saying is anything mechanical is probably going to need break in. I paid $25k for my truck, the manufacturer has a recommended amount of mileage to break in the moving parts. And Kimber still recommends 500 rounds as a break in.

Not that it matters now, but I believe that if you had used the 30 round magazines after you ran the 20 round magazines that they would probably function correctly.

I'm not trying to argue with you, but it's just something I personally have seen and experienced with this rifle/magazine combination. FWIW.

20s vs. 30s

The 30 problem has been ongoing. I believe that is one reason Ruger never marketed 30s. I have three mini's and have never found factory 30s to be reliable in my rifles. If it doesn't go bang reliably, I don't want it. Factory 20's work. I also don't like the 30's for bench or prone shooting. I prefer the 20's with rubber MagPuls installed. They fish out of a pouch or my cargo shorts a lot easier. If you want 30's, try them. If they don't work, dump em and buy 20's!

Ruger made 30-rd magazines in the 1990s and before. I know because I bought nine of them before the ban from a now defunct company called LL Baston out of Georgia.

I have been reading messages on this web site for many years now and I am not aware of any "ongoing problem". If there is a problem, it is most likely with the rifle and not the magazines. Rather than sending the magazines back alone, the rifle should have accompanied them. Mini-14s are famous for their reliability with factory mags, and a rifle that isn't reliable with all models of factory mags is defective.

What do you mean "ongoing?" I have never had a problem with my 30's. Nor have I ever seen others have a problem. Back in the day, I used to buy 30's all the time from Smitty's in Phoenix/Scottsdale and they all worked just fine.

20's vs. 30's

I mis-spoke. I have always found 20's of varying manufacturers to be more reliable than 30s from the same vendor. And ruger has sold 30's but they stopped selling them to the general public quite a while back before reintroducing them recently. I had a couple I bought with a rifle a while back but sold them off to buy 20s; two 30's for 8 20's seemed like a good exchange to me. While I'm sure it was more for polictical reasons, one has to wonder also if Ruger also found 30's to be too unreliable to sell to the general public (too many rma's), lots of junky ammo, etc. used by John Q. Public. I have read more than a few reports of reliability issues on this and other blogs with their latest production.

Anyway, you have to test and number your mags. If one develops issues, dump it.

Ruger Mini-14 30 vs 20 round factory mag

I own three identical Mini-14s (580 series). Bought them at the same time from the same dealer. The 30 rd magazine works flawlessly in two of the three Mini-14s. However, the magazine is loose fitting in the third Mini-14 and that gun has experienced several jams and the bolt does not hold open when the 30 rd magazine is empty. I think the loose fit of the 30 rd magazine in the third Mini-14 is due to a slightly different tolerance of the gun. The third Mini-14 works flawlessly with the 20 round magazine. Other experiments that I have performed with the Mini-14's gas bushing size also suggests that the 20 round magazine may be more reliable than the 30 round magazine. For example, if I use the .045'' gas bushing, the gun is very reliable with the 20 round magazine, but not reliable with the 30 round magazine. With a .05'' gas bushing the gun is reliable for both magazines. If you must have a 30 round magazine, make sure it fits snug in your gun.

I now have 7 30 rd mags and 7 20 rd mags, the 30's are all ProMag and they have never had any problems. The 20's are a mix of ProMag and Ruger. I bought most of my mags before Ruger started to sell 20 and 30 rd mags, so I really had no choice, before you were kind of limited because of the ban. Hopefuly in November there will be some changed in DC (Disturbed City), and things will change for the better and we will be able to breath easier for the few years.

If you modified the rifle from stock configuration you cannot blame the 30 round magazines.
