Well, I just bought a brand new Remington r-25 in. 308 and am having problems with it ejecting shells... when I'm shooting Steele cased ammo (tulammo) I get about twenty rounds off before it jams and with brass ammo (Winchester/American eagle) its jamming about every tree or four shots. I put about two hundred rounds through it hoping it might clear out but no, its still doing it. Ive been shooting for a few years now but I'm new to the whole ar/semi auto world. And help is much appreciated
ARs like to run wet. Clean it real good, lube the crap out of the bolt, and try again.
I've heard good things about Break Free, but have never tried it. Bob Downey likes Lubriplate 130-A. I'm using LSA medium weapons oil with good results, but will likely switch to Lubriplate when I run out.
Well just got back from the range after doing what you said and for the most part its working well, only thing is I can cause a jam by firing to quickly... now as far as I know you shouldn't be able to do that right? I'm pulling the trigger fast but by no means do I have a fast trigger finger so still a little worried about it... it this something that might work itself out with somemore rounds through it?

When my 10A4 was new it didn't like anything but 180gr Rem. Anything else caused it to short-cycle and fail to eject. Sometimes when it did eject it wouldn't pick up the next round. Now (a few hundred rounds in) it runs fine with 150gr Rem and 168gr Hornaday too (but that's all I've tried so far).
Do you think it's short-cycling? If it holds open after the last round then probably not.
Well there's a slight chance its short cycling... out of about 350 rounds through it it has closed the chamber empty once, maybe twice... it has never failed to pickup a round though. I notice when it was first jamming on me it was leaving the spent cartridge in the barrel/chamber, but after cleaning and lubricating it it has quit that. Now when it fails it seems to be feeding the next round before the spent one is fully ejected. Would that be a symptom of a short cycle? Should I try heavier rounds?

Yes, and it wouldn't hurt to try a heavier round, but first check these posts:
Failure to extract and failure to chamber are fairly common issues, mostly related to ammo choice, cleaning and lubrication, but they can be QC issues as well.

I use Break Free CLP same as in the Air Force and it works well.
My AR-10T 260 Remington was very picky about the powder type loaded in the rounds I was using for a few hundred rounds (short cycling mostly), it has since become less picky. The powder burn speed in ammo for semi auto rifles is very important. This may be why some brands cycle better than others. Also heavier bullets usually are loaded with slower gun powders which helps gas guns cycle more vigorously due to more available gas pressure at the gas port. Too much pressure can break things and not enough short cycles the action. There are many articles floating around the web on this and it is also addressed in Sierra's latest reloading manual.
I would also recommend trying different ammo/bullet weights as well as shooting your gun more. If it is not reliable with several brands after 300 rounds I would call Remington.
