First Range Session w/ My New LR-308B...?'s

I finally got to try out my new DPMS LR-308B. If I didn't suck so bad, she would have been a tack driver.:)

I fired 38 rds. My first 19 rds, I sighted her in, and the next 19 were decently accurate, the bullets were hitting the target exactly where I aimed, unfortunately I'm still a little shaky due to being a glass noobie. I was getting pretty good 4 shot groups, but I seemed to have a flier on one of the five rounds every time.

Oh, first I forgot to mention I was shooting the Lith. milsurp ammoman has right now...

My 38 rds fired flawless. My buddy grabbed a new mag, and the first two tries he didn't seat it properly. I took both of the rds that I wasn't sure if the bullet got compacted, so I took them out and charged the rifle for him. He took one shot and it jammed. Me not paying attention(being stupid) pulled the charging handle back and released, thinking the mag didn't chamber the rd. When that didn't work, I broke the rifle into two peices and noticed that the casing didn't eject from the chamber.

Now for the questions:

Edit:

1) Solved

2) What could have caused this? The extractor doesn't appear to be damaged.

3) When I get the brass out, what should I look for to make sure my rifle isn't damaged.

Thanks for bearing with my stupid questions.:)

Did you clean the chamber out real good before firing it the first time?

Any residue of oil or grease can make the chamber a bit tight and cause the extractor to not be able to hang on to the brass. I'd make sure the chamber was clean and dry and shoot it again before worrying about it much.

Without a proper chamber brush it's kinda hard to get to it so be patient and try to get in there as much as possible and make sure its clean. Qtips are handy as a "when you don't have anything else" tool.

Can't imagine you hurt anything. Look for obvious overpressure signs on the brass of course, flattened primers etc but you shouldn't see any of that with the ammo you are using. I've had nothing but excellent results with that ammo.
Never hurts to check though.

Hmmmm, don't know anything about Lithuanian Milsurp ammo, but you never know.

I would just scrub it out really well, inclusding use of a chamber brush, properly lube and try again. Sometimes the grease they coat them with can be a little difficult to get out of all the nooks and crannys.

I gave it a good once-over before firing the first time...Wiped it down and CLP'd it. But I could have easily missed some grease in the chamber.

I cleaned it really, really good again once I got home, I didn't see any signs of damage, so hopefully that second cleaning fixed it.

Theres only one way to find out, and I'll check back in tomorrow.;)

Tomorrow before I hit the range, I'll have to stop by the store and pick up a case of cheap soda's and water bottles for some real fun.:evil:

Had the same problem with a buddy's DPMS 308...it would not eject, Port, Aussie, SA.

Called DPMS, they said theirs is a Match 308 Chamber and thus would be tight for Mil-surp, further more, Mil-surp voided the warrentee :(

It went to a new home rather than dealing with it.

The DPMS 308 are noted to have issues with Mil-surp ammo...some folks have luck, many do not.

Good luck...They are a beautiful rifle.

They clearly state on their web page that they recommend quality mil surp for their rifles.

They list a few specific types to avoid, the ones everyone has had trouble with, SA specifically is mentioned.

http://www.dpmsinc.com/support/warning.aspx

DPMS recommends the use of high quality, domestically produced ammunition for best results and highest accuracy. For plinking and practice, we recommend only domestic, commercially manufactured ammunition or high quality surplus NATO specification ammunition.

Lithuanian surplus is NATO spec ammo, usually compared to Lake City for it's accuracy and quality.

If the rifle won't eat it I'd expect DPMS to make it work since they specifically talk about shooting milsurp.

Fixed it for you. :D

No offense intended, but you can't put cheap ammo through a FINE rifle like that, and expect good accuracy and reliabilty.

You don't really know what you are talking about with this ammo, do you :)

Several of the importers that specialize in this type of ammo have tested the Lithuanian surplus and find that it is comparable to Lake City.

Some info.... GGG is the Lithuanian.....

weight of fired cases:
GGG(Lithuanian)=181.6 avg
Lake city= 183.25
Winchester= 163.42
RP = 169.6
Federal = 184.12

Winchester varied the most ranging from160.8 to168.9
RP had a variation of 2 gr+or -
Federal had a variation of + or- 1.8
Lake city had a variation of 1.5
GGG had a variation of .5
GGG fit through Dillon case gage 8 times out of 10 after firing.
10 cases of each chosen at random after tumbling.

From the research done by the importers it appears that Winchester setup the manufacturing process for the Lithuanian plant that's turning this stuff out about the same time Clinton gave them M14s and no ammo. The fact that the brass is boxer primed would tend to lend believability to that since you'd really expect Berdan priming if it were "third world" equipment.

The brass does not have a NATO headstamp, they didn't receive the certification for that until 2005. This ammo was 2004 and before for the most part but the weight of the brass indicates they planned for this certification even then.

The company that's making it is ISO9001 certified.


Here's the companies website..... http://www.ggg-ammo.lt/en/index.php

GGG cartridges 7.62x51 GP11 are produced according to the requirements of STANAG 2310. GGG produces Case&Bullet Cups, Lead Cores and Bullets for these cartridges.

In 2005 cartridges has successfully passed the quality tests in NATO ERTC in Pendine and GGG has received a right to mark cartridges with NATO interchangeability sign.


The GP11 is a Swiss spec and it exceeds the NATO spec for accuracy. You could call it "semi match grade" I guess.

Bazooka Joe : Since I recommended this ammo to you, if your rifle won't shoot it, I'll buy all you have.
But.... If your rifle won't shoot this ammo, I'd be talking to DPMS and asking them why.


I've fired tons of this stuff in M14s, PTR91, DSA FALs, etc and never had a single problem. It's probably the best non-Match grade .308 on the market today. I just hope it keeps coming into the country after the next election. My biggest fear right now is some kind of import ammo ban rather than any direct gun ban.

You don't really know what you are talking about with this ammo, do you:)

Not a clue (http://www.ammoman.com/targets.html):

COMES IN SEALED MILITARY BATTLE PACKS
BRIGHT & SHINY
EXTREMELY ACCURATE - NEAR MATCH GRADE

There was plenty of cheaper ammo I could have bought, but chose this because of all the good things I've heard.

Edit: Bazooka Joe : Since I recommended this ammo to you, if your rifle won't shoot it, I'll buy all you have.


I really appreciate that, but I'm not convinced it was the ammo's fault just yet.

Bazooka did you find out the problem? I'm considering one of these rifles.
