Just got mine last week and I love it. I took the rail off until I can afford a decent scope. A2 flash hider will go on soon! http://i63.photobucket.com/albums/h138/dpkoons/EF7201AD-0A0B-4E3F-A255-3619157CE73D-1349-000002845852C89F.jpg Another light colored one! Looks great! |

That's a bummer, about the range and the issues you had. I've never had an issue with the bolt sticking like that before. I had a similar problem in a Winchester Model 70 one time where the bolt would rotate up, but extracting the spent casing was difficult. It was caused by a (badly) out-of-spec chamber which allowed the casings to bulge considerably upon firing. I haven't heard of any issues like that with the GSRs so perhaps take some different ammo with you next time and see if it still hangs? You could also try polishing the locking lugs to see if that makes it easier to cycle the bolt. Sometimes slicking the bolt up a little bit makes a huge difference.
|
|
Mine locked up probably 3 times out of 60 or so with my surplus crap I was shooting.
Once I had to use a log to smack the bolt back. I assumed it was because I was using crappy ammo? |
|
I haven't shot any surplus 7.62x51 ball through my GSR but I do have some laying around here. Maybe I'll shoot 30 or so rounds of it next time I get to the range and see if I get similar results.
|
|
If the bolt is hard to move most likely the head space is wrong.
If you are using surplus ammunition then try something new like federal. I have had similar problems with surplus military ammunition and hand loads I didn't resize correctly. |
|
I'll shoot some other ammo through it as soon as I can.
I've still got a 200 rd battle pack of the 147 gr ammo and the 35 or so rounds I shot through it Sunday were loose leftovers from a previous pack so I figured I'd use those to get a baseline zero and get dialed in with the good stuff. I'll let you guys know what happens when I do. Hoping for that to be sometime later this week or next. I really hope I dont have to send the gun back to Ruger. I was planning on using to deer hunt for the first time. Dad has been making noises about not going hunting anymore and I wanted to go at least once with him.... If the gun goes back to Ruger, its not going to be back in time to hunt in November.... |

Sounds like there's a good possibility its an ammo issue, but I can definitely understand wanting to use the surplus stuff for range time since you've got a good amount of it already. Good luck, let us know what happens. |

|
mine is all "FLB" argentine stuff and it does stick sometimes.
|
|
Hmm... Definitely try commercial ammunition before jumping to further conclusions, but the Winchester I spoke of earlier with the out of spec (oversized) chamber made similar marks on brass.
|
|
Planned on trying another type of ammo that is commercially available.
Its interesting/annoying(??) to me that there were no issues in feeding the ammo, but only on extracting the fired brass... Also, its kinda tough to tell in those pictures, but the marks on the brass are all in about the same location...IE same "height" or distance from the neck of the brass as one another. |
|
I'm assuming you've visually inspected the bore for rings or burrs that may be causing that? I've had friends with rifles that needed the bore of production rifles reamed before. It's pretty inexpensive but if you can't see or feel any protrusions or imperfections I think you can rule that out.
|
|
I did a quick look down the barrel to boresight it and to make sure that there was nothing obstructing the bore before firing it, but no detailed inspection of the chamber.
As soon as I get the gun back from my dad I'll look more thoroughly. |
|
Sounds good. I would still shoot it again with other ammo to see if commercial .308 gets the same scoring on the sides of the cases first. No sense in jumping to conclusions since I've never heard of issues like this with Rugers before.
If there are marks on the new brass, it can be hard to visually identify burrs, so wrap the end of a rod with a cotton cloth (something you know snags easily) and slowly swirl it around in there. If you feel or hear it catching on anything, there are probably burrs in the chamber left over from machining and it will need lapped. If there's no snagging, but you're still getting those marks on casings, the headspacing or chamber dimensions are likely out of spec and I'd definitely contact Ruger about it. I hope that's not the problem but we won't know until we get to there. Good luck! |

Thoughts? You do understand that you're shooting 7.62x51 NATO spec ammo in a 308 chamber? I'd assume that this was a headspace issue until proven otherwise. As others have suggested, try some commercial 308 ammo, maybe even some Federal GMM; the odds are good that you'll be fine. |

What's the Difference? |

OK, I'll flesh this out a little.
As noted above, the chamber specs differ between 7.62x51 NATO and 308 Winchester. However, the cartridge specs are the same. In an ideal world, the two types of ammo would be interchangeable. Most of the time we can get away with it, but not always. Here are some issues that can be encountered by just randomly interchanging the two: 7.62 ammo in a 308 rifle: 1) 7.62 ammo is generally loaded to lower pressures than most commercial 308 ammo, so that's usually not an issue. 2) All 308 chambers are not the same, even for a given model of rifle from a given manufacturer. As a chamber reamer is used, it wears down, producing the tightest chambers that are still within SAAMI spec just before the reamer is retired from the assembly line. 3) All 7.62x51 ammo is not the same, especially given the wide range of countries that produce it. 4) If you have a situation where 7.62x51 ammo that is on the sloppy side of tolerances is fired in a tight 308 Win chamber, this can potentially create a short headspace condition, which can lead to difficult extraction. I believe that this is the situation that MaxxII is experiencing. 308 Win ammo in a 7.62 rifle 1) Commercial 308 ammo is often loaded to higher pressures than 7.62x51 ammo. This can lead to issues, especially in semi-autos. 2) The combination of a 7.62 chamber that is on the sloppy side of NATO spec plus commercial 308 ammo that is on the tight side of SAAMI specs can lead to a long headspace condition. This can lead to excessive brass stretching and potentially case head separation. HTH. You can't just say that "one is smaller than the other" and expect that to explain all of the various factors involved. |

You can't just say that "one is smaller than the other" and expect that to explain all of the various factors involved. I had originally assumed that since I was shooting 7.62 in a .308 I was good to go. After your initial post, I did some digging and discovered the link you just posted. We all know what happens when you assume, right? Anyway, I just got a membership at a private range yesterday, hoping to have time to take the GSR and shoot it this weekend with commercial .308 loads. That should determine one way or another if the gun needs to go back to Ruger, or if it just doesnt like 7.62 ammo. Obviously, I'm hoping for just not liking 7.62 ammo....... Gasman, thanks for posting that all up and summerizing it. |

Gasman (or anyone that knows),
Is difficulty extracting mean that I should stop shooting that type of ammunition? I mean, is it dangerous? For the price I got this ammo I would like to keep shooting it, of course. |

If my rifle has to go back to Ruger to get the chamber reamed out, then I might try it again, after measuring everything.

If not, I'm just going to go along with the fact that my rifle really doesnt like 7.62 ammo. Ok so I was curious regarding the whole 7.62x51 NATO vs. .308 thing, so I went shooting this morning and ran 20 rounds of Federal XM80C and 80 rounds of AE M1A through my GSR... I didn't have any issues with the bolt sticking, poor feeding or extraction, or anything like that. If I had been blindfolded, I wouldn't have known the difference between shooting it and any .308 rounds. In fact, it shot pretty well with the cheap XM80C and I wish I would've bought more of it when I had the chance! It isn't not possible to rule out your particular rifle as the cause until you put some commercial .308 through it, BUT I highly suspect the tolerances on the ammo you were shooting may be loose, since both of the NATO loads I shot today were from Federal which I trust has better QC than bulk packaged ammunition of foreign manufacture.

I have had my GSR since July and I love more every time I look at it. This weekend I decided to mount one of my Burris 2x handgun scopes to see if it was useable and it is! I am really pleased with the look and operation of the scope so far and I am off to the range in the morning to see how it performs. http://i34.photobucket.com/albums/d139/musicman10_1/IMG_7318.jpg Sweet! Nice sling too What part of the state are you from? Maybe we can hit the range together sometime. |

Using tools such as GO-NO GO-FIELD headspace gauges and the Hornady headspace gauge would answer a lot of these questions. But, if you have to ask yourself "is it safe to...", you probably already know the answer. |

http://img.photobucket.com/albums/v474/GUNRUNNER84/DSC01111.jpg?t=1350065696 Mine, bought last weekend from an arfcommer. Quickly becoming my favorite rifle, not sure if I'm sold on the scout scope though. Looking at the XS rail with a traditional scope. Can't go wrong with the XS rail for $80 or so. If you do decide to keep the scout scope, you can still mount it on the XS. If not, you're no longer stuck using Ruger's rings, and you get to keep your rear sight at the same time. It's a great piece of kit. |

I liked my GSR so much that I put together what I call my "Mini GSR" for a trainer and a small game hunting rifle to go with it. Both have (or will have shortly) 16" threaded barrels, polished bolts and internals, improved factory triggers, Leupold rings, 1.5-6x scopes with illumination and BDCs, Rock Mount bipods, aftermarket top rails, Blackhawk cheek pads and Blackhawk mountain slings with QD swivels, laminate stocks, detachable 10-round magazines, and they are within .75" and about .5lb of each other in size and weight. I just got back from the range today with both rifles. I finally bought myself a chronograph so I was able to finish the testing I started with the GSR back in August (see page 4). http://imageshack.us/scaled/landing/152/capturevyw.jpg Previously, I had noted that off-the-shelf 150 grain Federal and Hornady loads were shooting better groups and working better in conjunction with my BDC reticle than comparable factory loads in 165, 168, and 175 grain varieties. Well today I chrnono'd a few different loads, off-the-shelf AE 150gr. FMJ, AE 168gr. OTM, Federal Fusion 150gr. SSP, and Federal 168gr. TSX. The average 168 grain loads were *barely* pushing out of my barrel at 2,450 fps with a high of 2,501 and a low of 2,420 (79-81 degrees, altitude 2,157 ft, 11mph winds, 32% humidity, barometer 29.88"). The 150s were doing a respectable 2,675 on average, with a high of 2,692 and a low of 2,661. I'm definitely sticking with 150-grain bullets in my GSR after the results I got today, and hopefully I'll be back out to the range next month testing some handloads I'm working up. The goal is to run about 2,750 fps consistently with a 150-grain bullet out of the 16" barrel. http://i100.photobucket.com/albums/m35/Undividedusa/IMAG2203_zps3a58ca6a.jpg http://i100.photobucket.com/albums/m35/Undividedusa/IMAG2205_zps63bbbadf.jpg Very cool Can you tell us more about the .22?

Thanks Outkast. I always love the updates. Glad you enjoy it! Once I work up a winning load for my rifle I'll be sure to share it for any reloaders we may have here. |

Okay went back to the range today and got much better results.
Using the same ammo as yesterday: Federal 308 150 gr soft point Winchester 308 180 gr Power Point Hornady 308 165 gr SST Superformance I got much better results. The 150 Gr Federal actually shot about 3 inch groups at 100. The Winchester 180 Gr Power Point was out to about 4 inches and the Hornady 165 SST Superformance was actually at about 1.5 - 2 inches at 100 if you discount the one I pulled by jerking the trigger.....I knew I had done before I even looked. Much better range session than yesterday and feeling much better about this rifle. I do need to get a bipod for it and might very well look into the Rock Mount that OutKast uses on his rifles. I had transferred a little thumbscrew bipod from my 10/22 to the Scout today before the range session and while it worked, I noticed it was loose at the last shot, so I'm guessing it wasnt designed to work for 308 recoil. OutKast, can you post a better picture of how your Rock Mount bipod is attached to your rifle? I like that you've got a sling with it too..... |

You'll notice better and better results each time you hit the range. It took me some time getting familiar with the rifle, especially with all the stock spacers removed. I like the short LOP but it was definitely a huge adjustment for benchrest shooting. I can definitely get pictures of my bipod for you, just give me a bit. I forget, are you shooting with irons or do you have a scope on yours? ETA: Never mind, I remember you got the Leupy 1.5-5x right? |
