Title: Light Strike or R9s with GD 115gr Advice Needed
Post by: Chihuahua TN on May 15, 2010, 07:12:11 PM
Hello Rohrbaugh experts I a FTF (failure to fire) today, and I need some advice from everyone. I have an Early Deer Park R9s with 101 rounds total through the gun all have been Gold Dot 115gr rounds.  To date there have been no jams, ejector failures it been 100% failure free.  I usually fire 13rds once a month through the gun…today it has been around 3 months since I have fired the R9s and on 7th (last round in mag) I got the dredged “click”, waited and ejected the round.  I fired my other “carry mag” and all 6rds when off without a hitch.  I also re-chambered the round and still the round did not go off when fired.  The gun and spare mags have been back pocket for 3 months. Should I be concerned that my R9s is exhibiting light primer strikes or this hard primer ammo related? I have personally seen this with Hornady CD ammo but never with any Gold Dots in any of my guns.  Below is a picture of the round along with other spent shell casing from the mag.  
Thanks for all help,
Mike

I don't see a light primer strike among the three. A long-distance diagnosis would be that there was a defective primer -- a primer that was rendered defective during manufacture or was somehow later degraded by some penetrating agent. I've never had a Speer cartridge of any caliber fail to fire, but "Murphy's Law" is always in effect. If it were my call, I might just purchase another box of Gold Dots from another lot, fire a few of the new cartridges for test purposes, and then hold the remaining cartridges from the box which contained the "dud" for range work.

In the meantime, I would consign that "dud" to some deep and stony grave.

Mike, you know that I know that R9. Never had an issue with light strikes, and by the looks of those three pics, there are non there.
I certainly agree with Richard, and I believe this too is ammo related. This really bothers me because I had high hopes with Gold Dots as the best SD ammo out there with the best consistencie.
Please try another lot and report back on this.

I agree with Richard.  I would consider that a dud.  I have never heard of any problems with Gold Dots either.  There's always a first time as Richard pointed out with the Murphy's Law thing.  No light primer strikes that I see.  

Good suggestion on the remaining box and burial spot for the dud.

Does not look like a light strike...  Your R9 seems to be working fine  ;D

Thank for everyone responding, I also believe that I had a defective "gold dot", the round came from a 50rd LE box, interesting I know. Its frustrating to know that it was in my carry mag. I need to cycle through my carry ammo more often. I'm going to shoot some more this week, let guys know how it turns out,

chameleon the gun is awesome, I even obtained a set of blue CF's to add for show,
thanks,
Mike

Hey Mike that gun was ment to have factory black CF's on it.  And would you belive I have a set that I would LOVE to trade for a blue set.  Ain't that a coincidence!   ;D

I have/had 7 sets total of blues.  Some were on guns some were not.  I wished I still had 7 sets!

Me too!  Maybe you would sell me one of your extra sets, then, you didn't need!    ;D

*Update*, today I shot 40rds GD 115gr from another box without any issues (141 total on same spring). I still am perplexed that "the one GD round" is the only issue I have ever had with GD ammo. I also introduced the guy in the next lane to Rohrbaugh's after one mag his response was ..."AWESOME",

Mike.  Certainly glad everything turned out well.  Thanks for the update.

Post by: ccoorreeyy on May 23, 2010, 08:19:16 PM
That's good news.  Glad it was just a dud ammo.  I think with the ammo companies being SO busy trying to catch up on orders that things are making it out the door that did not used to.

I feel better now. You probably more than doubled the round shot count from that pistol in that one outing!
Thanks for the update.

The round on the right looks to me to have a lighter strike than the other two.  

I'm far from expert, but it looks like the "dimple" is smaller to me.  

Is that just my eyes?

While the casing on the right in the photograph shows a slightly different firing-pin imprint and may indeed have been the culprit (Mike didn't specify which one it was), that is not what I would consider to be a light primer strike. Rather, it appears to me to be a clear stike pattern of sufficient depth to have ignited a properly functioning primer. The slight difference in appearance may be due to a slightly harder primer -- but having been struck as hard as it was to leave the resulting impression, the primer material should have ignited and the cartridge should have fired.

"S***" happens, as we used to say, and even Speer and its superior Gold Dot ammunition are not exempt from "Murphy's Law." I think this was simply an extremely rare Gold Dot "dud" caused, as previously speculated, by either a glitch during manufacturing and/or contamination of the shock-sensitive explosive primer material by a penetrating agent of some type (e.g., solvent, oil, moisture, etc., etc.).

I agree with Richard. The light primer strikes due to hard primers that I have seen in Hornady CD look like fried eggs with no dimple. That is a different animal even though the results are the same as yours except yours was a one-off.
Title: Re: Light Strike or R9s with GD 115gr Advice Neede
Post by: kjtrains on May 26, 2010, 01:11:33 PM
Yep!  A dud is a dud.  That primer was hit hard and deep enough to go off.  Sometimes things just happen.  Richard explained it well.  Murphy's Law shows no personal favorites.

Regarding my previous statement that Mike had not specified the "culprit," a third look on my part shows that he didn't need to do so. The "dud" would indeed appear to be the one on the viewer's right. I had been concentrating so much on the primer strikes that I failed to notice the difference in height of the casings in the container. The two cases to the viewer's left in Mike's photo are obviously lower in the container, indicating that each of them fired.

Further than the aforesaid clarification deponent sayeth not other than to reaffirm all other aspects of his previous testimony.   ;)

Sorry. I'm in the middle of writing a federal appellate brief and just checked in over here for a breath of fresh air.   ;D

I love it when a plan comes together!  Hope the appellate brief goes well.

I am sorry for the confusion it was the one on the right, and it did not fire after 2nd attempt as well. Thanks for everyones responses....I.. as of now I am believing its a dud, however will keep everyone informed,
Mike

Just for fun, how about you try that round in another gun?  

I'd be curious to see if it fired.  The strike on the on the right still looks significantly smaller to me...
Title: Re: Light Strike or R9s with GD 115gr Advice Neede
Post by: tracker on May 26, 2010, 10:08:00 PM

What would be the point of that other than to show that the R9 may tend to be a light striker? Of course you could verify the dud aspect but it would be a bit disconcerting if it fired.

Thanks.  This whole thing has got me curious.  If it doesn't fire, maybe you could take the round apart and see if the primer has any, uh, primer stuff inside it.

Well today I took the infamous 9mm 115gr GD round to the range and it would not fire in my Beretta FS92 which eats everything. This is the first GD 115gr dud I have ever had. Thats good news for my R9s,
