Hello, just got 500 rds of bvac 180 gr new brass plinking ammo advertised at 1175fps in the mail today and fired 5 rds through chrono. I got 1135-1150 from my stock glock 29. THat seemed a little fast for the short barrel but ok. Then I picked up my brass and found this one. Not sure what to think, the rest look normal but I have shot 40 and 10mm glocks for years and never seen this. Is this a "glock smiley face" that people talk about. Im obviously not going to reload this and I was wondering if I should even shoot the other 495 rds. What do the experts think

Looks like its been "Glocked" by your 29. Either it was a bit hot, brass was soft or a combination of the two.

I would say a new barrel is in order.

It does not look that blown out to me, but frankly I would not fire it in a 29. Sounds like a good reason to buy a 610.
 
I have plenty of other 10s including glocks with kkm barrels, but that 29 is my ccw gun and I wanted to keep it stock and practice with it. That particular one has only been fired about 15-20 times. I have shot 40 s&w out of my stock 27 almost that hot with no problem.Im just wondering if its bad brass from bvac. The brass says armscorUSA.
 
I had that happen years ago, circa 1990, with my Smith 1006. The brass was new, unfired Winchester and the load was nowhere near max. I trashed all the Win 10mm new brass and have never had the problem again.

In 1993, I bought a NIB Glock 20. Those are the models with lesser support at the feed ramp. I've never had that with any 10mm round fired through the G20 and that includes Buffalo Bore. My BB stuff used Starline Brass.

Before you think "defective" gun, think "thin brass".

As to armscorUSA, I've picked up dozens of their fired 40 S&W at my gun club. Pretty much every one had the bulge associated with Glocks but funny thing was the guns weren't Glocks. When I showed them to the shooter his only reply was he didn't hand load so I could have them. Yeah right.

Here's a couple of pictures of their fine stuff fired from either a Smith or Beretta; I forget which.

The "glock smiley face" comes from 1 or 2 things with my Glocks: 90-99% hit rates on head shots, and the wear marks on the barrel.
 
No wear on my barrel, new gun. If I get a break from my 1 & 3 year olds today Ill shoot some more. I'm not thinking defective gun. I'm am questioning the brass. I may shoot some through another brand of gun today. This is cheap 20 dollars for 50 bvac ammo and the numbers on the chrono were very impressive. Very low extreme spread, I just hope they stop buying armscor brass. All yhe ammo I bought from them before was starline brass.anyway thanks for the replies, I was just wondering if this was a warning to stop shooting this stuff. I have loaded 200 gr xtps at 1250 in my hunting Glock and never seen this.
 
now Im sure it was bad brass. this one blowed out. I still have all 10 fingers (well 9 3/4 but thats a whole nother story) and the gun seems ok. This one was shot in my delta elite. the other 4 were around 1200 fps then this one was 1000 fps. it blew the delta triangle off the grip and jammed. so out of the first ten rounds one almost blew out in a glock and one did in my delta. certainly not going to shoot the other 490 rds. I guess Ill be talking to bvac and finding out how good their customer service is.

Bitter root valley ammo company. I just want the ammo replaced, I dont think that's unreasonable
 
I have fired a few thousand rds from them without problem, as long as they make this right by replacing ill likely fire thousands more.if not someone else will sell me some. I honestly think they got a bad supplier of brass or maybe just a bad batch. However I don't think I'll fire any more armscor brass. I asked them to replace it with starline brass since that's what all my other bvac ammo was
 
ok here is their reply,

I have received your email about the concerns you are having with the 10mm ammo. I have been advised from the quality control department that the colt feed ramp is not supported well enough for the full power 10mm and has nothing to do with the brass. We don't use starline brass anymore. We can replace the lot you have with a lighter load for sure though at 1100 fps. Please provide your shipping information and phone # and we can recall the ammo and replace it as specified above. I look forward to hearing from you.

Thank you,

Not sure how to handle this. if this is true it doesnt say much for colts design team, nor does it explain why the first pictures fired from my g29 are abnormal (assuming this isnt normal for a glock 29) . I think Ill wait for some replies concerning this before I act on it.

Thats odd.
My buddy had a 1st. Gen Delta Elite when the 10mm first came out.
At the time Norma loaded 10mm up there with the hottest pistol rounds on the planet.

He never had a guppy belly case, and he for sure never had a blown case.

The only problem with the Norma loads was running out of breath before you traveled far enough from the line to pick them all up.
They were ejected just slightly slower then the bullets!!

Also, see this about hot 10mm ammo.

Note the velocity in the Glock 20 and Colt Delta Elite!

OK to close, BVAC has very good customer service they emailed me twice and after getting my phone # called me. They said the only problems they had was with deltas, and they would replace my ammo or I could keep it and shoot it in my glocks and they would send me some more. So I went out and shot 30 rds in my kkm barrel in my g20 and the brass is normal, no bulge, I dont think Ill reload it, but I just shoot it in that gun.
BVAC said they had already started putting a warning on that ammo to not use it in deltas and I also noticed that underwood ammunition also had a disclaimer against shooting their ammo in the delta.
 
If they are calling 1200 fps +p, what are they loading it with? 231?

Sounds like they are using something a little too fast.

The Delta and G29 both have support issues. A barrel swap will fix them but seems most people just fire away without looking for warning signs.
 
I agree with you intercooler when it comes to handholds, but I was under the impression that one could fire any factory plinking load in any 10mm.
 
BVAC posted this on their FB about 1 hour ago.

The support in those are bad but maybe they had a mistake load too.

FYI: Our BV10-2N and BV10-3N loaded between 1/01/12 and 3/01/12 were loaded to full power 10mm loads. Because some firearms have unsupported chambers, we have changed our 10mm loads back to a mid-range load of 1175 fps.
 
Someone pointed it out the brass isn't the usual Starline. I posted that to their FB page that they are using sub-par brass. It's a combination of both.
