I WAS JUST CHECKING TO SEE IF ANYONE HAS HAD ANY PROBLEMS WITH FEEDING ROUNDS ON A DPMS 308? I HAVE A REMINGTON R25, AKA DPMS THAT WILL NOT FEED 147 GRAIN ROUNDS. IT WILL FEED 1 OR 2 ROUNDS AND THEN NOT STRIP ANYMORE AFTER THAT. I CALLED REMINGTON AND THEY HAD ME CALL DPMS AND THEY SUGGESTED TO USE A DIFFERENT BRAND OF AMMO AND A DIFFERENT WEIGHT. I DID THAT AND WENT TO 168 GRAIN REMINGTON MATCH AMMO WHICH FEEDS FINE, ALTHOUGH ONCE IN AWHILE IT WILL FEED AND EXTRACT AT THE SAME TIME WHICH LEAVES ME WITH A SPENT SHELL AND A NEW ROUND IN THE CHAMBER AT THE SAME TIME. I ASSUME THAT WITH 147 GRAIN AMMO THAT MY BOLT IS NOT BEING DRIVEN FAR ENOUGH BACK TO STRIP A NEW ROUND FROM THE MAGAZINE. I WOULD LIKE TO USE THE SLIGHTLY CHEAPER AMMO FOR TARGET PRACTICE, SO DOES ANYONE HAVE ANY IDEAS THAT MAY HELP SOLVE THIS PROBLEM?

A few things. DPMS did have some magazine issues a while back and they were replacing them as needed. If your rifle is pretty new probably not the issue. Some folks have tweaked the lips of the mags to make them perform better.

Possibly order a C Products and a 7.62 Magpul Pmag and see if your troubles go away. Both are cheaper than a box of ammo and perform better than the factory mags

i will try the c products magazines next time since i have some of those. i did not at the time when i first fired my rifle. i got my r25 about 2 years ago when they first come out from remington, i just happen to luck into buying it when another guy could not. i think i got the first one in arkansas. but i have not been able to get back to the gun club that i belong to since i first got it to try thr c products magazines with the 147 grain ammo. i hope to soon. i will let you know if it works or not. i may just buy some pmag also to try out. thanks for your help.

The pmags are ultra reliable, a game changer with these rifles.

Another thing would be to make sure you have your bolt carrier lubed pretty well to reduce the friction which will reduce the force it takes to eject and rack another sheel

I know I'm kinda late posting any thing in this thread . Hows the rifle shooting ?

Are your 147 gr. projectiles in the form of 7.62 NATO ammo ?

Its not That it can't be fired in most 308's , but some match chambers may not like them at first or at all.

As said above ,keep it well wet with lube & of course try diff. manufacturer mags.

I had a similar problem with mine. Worked the mags etc.... I would end up double feeding and crushing rounds. Check the tips of your rounds after this happens. Does it look like they are striking too low on the feed ramps. I have to send mine in and have them recut. Worked perfect after that.

well i wasn't expecting more responses, but since i have some more i will update a little more. the 147 grain is winchester 7.62 not straight 308. when i started using remington 168 grain match it shot fine for abount 60 rounds. i only had 2 misfeeds and both times i had a spent shell sitting on top of a fresh round in the chamber. they were not tightly jammed because i just pulled the charging handle back and rolled the gun on it's side and the both fell out. the bolt was not wet with oil, but it was oiled, but not maybe enough. i did not see any damage or marks on the rounds when they would not feed when using the 147 grain. as i think i said before it would eject the spent round, but not strip another from the magazine. i will order some pmag magazines and also try the c product ones that i have with the 147 grain and see if that makes a difference. plus i will make sure the bolt has plenty of oil on it. thanks for your ideas.

hello everyone. it has been awhile since i have been to the forum. in regards to my original post about my feeding problems on my r-25 308/dpms rifle. i bought some c products magazines and took them out last weekend. even with those magazines i still had feeding problems. so i sent a email to remington and they answered today. they said to turn my mag release in one more turn. that would hold the mag tighter and also more it up a little. i hope to try that this weekend and see if that may fix my problem. i made sure everything was lubed well and checked to make sure everything was tight. i still ran the 147 grain winchester 7.62 ammo since that was where most of my problems are and still remain. i still plan to get me some pmags for it and try those. i may just have to run the 175 grain to keep malfunctions down. and in case anyone is wondering if it is operator errors, i do not think that i am the problem. i just finished building my ar-15 in 223 and i ran 150 rounds thru it the same day with not one malfunction. so i am pretty sure that i am not the problem. but i have been known to be wrong before. anyway, i just wanted to update all of you that gave me some ideas of where to look. thanks for your time

You may just find that the gun is tight and once you get some time on it with the heavier bullets it may be fine with the lighter stuff. PMAG is still worth while, you will like them.

FYI - I didnt reread the thread from the beginning but when we say run these things wet when new it means nearly dripping with oil (mobil 1) and not a light film like with an AR-15

I had a similar issue with an AR-15 and it was a problem with the gas block and tube alignment.

Im surprised Remington didnt send you to DPMS directly.

Thanks for the update. This is a curious one

PMags are great, worth twice the price. I have purchased a few and am planning on purchasing more-I'll never use the factory metal mags again. The PMags just function so smooth you'll never go back.

I'm having a similar problem with my AP4. Mine's a failure to extract, as is shown by the brass when I get it out. It's notched and even torn some of the case rims.
My gunsmith said the factory chamber polish is fairly rough on these guns, and he can polish it out better without affecting accuracy. He also said an extractor upgrade would help.

Yeah DPMS has been known to let a rough chamber out. They will also usually take care of it under warranty

Make sure there are no burrs on the extractor & yours also sounds like its got a rough chamber .
The rough chamber will slow the extraction down , which slows the BCG 's rear ward travel.
Also check to make sure your ejector is not too stiff & is moving freely in & out of the bolt.
With one round in the mag & upon firing , will the bolt stop lock the BCG back ?
I have found on some mags , you need to load them up & let them sit a couple of days loaded to break the spring in .
