Mini 14 Ejecting Issues

5 out of 20 fired rounds during today's range trip ended like the photo attached shows. Only thing I can think caused this is that the casings were not trimmed to exact length since these rounds were reloads. As the case was ejecting it would get stuck. Is this something that can be caused because of a case length a bit too long? It's a 582 series mini 14. Any thoughts? Thanks...

*NOTE* I mocked up a case and took a photo here at home, but the ones at the range did show the case leaning towards the correct way to be ejected off to the side.

Under powered rounds?

The mini 14 uses the spent gasses to cycle the action is it possible that the reloads were under powered?

Try some factory ammo and see if the problem continues.

That's a good point, I know the powder was measured with a perfect powder measure so yes that could jiay be it. I havent fired factory ammy but did fire some of my reloads where I used a scale for each round and didnt have this problem.

I purchased a mini14 tactical in March and have fired less than 50 rounds of store bought ammo. It jams on the ejection. I broke it down to clean it and the ejection mechanism looked like it was damaged/broken or had excessive wear for less than 50 rounds. The rifle is now in the hands of UPS to return to Ruger. The ejection mechanism looked like a pin was not installed correctly. The customer service rep was polite and immediately said to send it back for repairs. Could this be a recurring problem that they are aware of??

I have a picture of my bold but don't know how to post it.

I had the exact same issue with my 582 rifle. Long story short, I ended sending it back to Ruger where they replaced the bolt, mag latch and repaired the slide. If problem persists with other ammo you might have same problem. I also had stovepiping issues.

Reloads were CCI #400 primer, once fire winchester brass, Imr 4198 weighed at 19gns, Hornady 55gn FMJ w/ cannilure...

I've also fired 5.56 and had the same problem. I may just have to send to Ruger and have them take a look at it...

Yeah if it's still doing it with factory loaded 5.56 I'd say its time to give Ruger a call.

4198 is a fast burning powder and 19 grains is not enough to cycle the action. I do not recomend 4198 in a Mini 14, you should consider IMR 4895 or 8208 XBR if you want to shoot IMR powder. I recomend no less than 24 grains of the 8208 or 4895. You might get by with a little less but not buy much. Other powders to consider are RL10, H335 AA2230.

Here is a link to a powder chart I use. But, most of all, get a good reloaders manual and follow their recomendations. kwg

I appreciate your advice. I currently been following 49th edition Lyman. I been wanting to get into H335, it mat also be time to change it up considering IMR 4198 doesn't burn quick enough. Thanks for the chart. I guess its time to pull bullets or shoot them through a bolt action.

4198 burns too quick and does not generate enough gas to operate the system. It would be great in a .222 or .22 Hornet bolt action but not a semi auto. kwg
