Quoted:
Put 25 rounds of PMC brass with no problems then when I run a mag of steel case it would eject the spent casing but not pick up the next round in the mag.would the problem be more lube or just shitty tulammo? Tulammo, especially, tends to be underpowered compared to good commercial and military surplus loads. It's possible some more lube and break-in will help your rifle run on the weaker loads, or it might require swapping buffers or opening up your gas port to get it to function on a wider range of ammunition. Realize that if you open the gas port to run the weak stuff, you'll likely be over-gassed on the good stuff. There are other steel options besides tulammo, too - I don't run my rifles with tulammo because most of them don't run well on it, but they eat up brown and silver bear without issues at about the same cost. Or stick with brass that works and have no problems, but a bit less ammo to shoot per dollar spent. |

Any chance you can give us any details on the rifle (brand, barrel length, gas tube length, chamber type, gas block or front sight base, stock type, buffer type), as this may help provide some insight for troubleshooting purposes? It could be related to several possible causes like a gas leak, lack of lube or cleanliness, chamber issues, buffering configuration, ammunition, etc. Start with a thorough cleaning of the barrel, chamber, and bolt carrier assembly, making sure you use a chamber brush. Then lubricate the 7 bolt lugs and rails of the bolt carrier assembly until they are good and wet (glissening like a glazed donut) with a quality lubricant, my recommendation is Slip2000 EWL (Extreme Weapons Lube), as this will help eliminate fouling and lubrication issues.

Not sure of the specs of your rifle but I will share mine cor a comparison. BCM SS410 upper with Noveske lower, Geissele NM high speed trigger. Anyway, the important info: mid length gas and standard carbine buffer and action spring. I only tested about 100 rounds because I'd rather not shoot steel through this one, I'm putting together a lower cost rifle for steel/cheap ammo use. However the BCM has cycled whatever ammo I've tried, bolt open after last round etc. Always keep it lubes well. If you have a heavier buffer and or not enough lube that could be the issue.

Frakenbuild,but other then steel cased it's been reliable will try different buffer weight and a good cleaning just wanted some information so I could help deduce the problem. Probably won't use steel cased any way I just had some so I thought i'd shoot it.

I solved the issue the lo-pro gas block had become loose and moved forward just slightly and was causing it to short stroke,so I applied more thread locker and repositioned it and no more problems.I'll probablt be getting a SLR rifleworks adjustable clamp on gas block as the one I have is a cheapo one any way.

The only steel cased ammo I would buy would be in 7.62x39mm and only if I couldn't locate any brass cased ammo. In other words, in an emergency only. This stuff is the lowest quality ammo available and your problem is common.
Spend more to get better or consider reloading as the next progression in your hobby. |

Burnt 223 Wolf steel case ammo by the pallets in full auto rigs over the decades, so the problem is not all steel case ammo, but underpowered ammo that may be the problem in itself.
Even funny, have a older lot of wolf 62 gr that will print 1.25" @100 yards out of one of my NM rigs for a 10 shot group, so can't even say that overall, steel case ammo is just bad on the whole. |

I agree but it was all that was available at the time of purchase and I wanted to use it up |
