I had tried some Q3131 a few years ago and it sucked in my gun. Nothing but short stroking. I remember posts on here with everybody saying the "white box" winchester was crap.

Now it is great stuff.  Abybody have the same experience? Is the newer Q3131 much better?

I've run 500 rounds through a new Bushmaster without a problem... Good stuff!

It shot terrible in my gun last week a 16 inch heavy barrel bushy.  I will try it in my varminter I bought last friday this week.

Correct me if I am wrong, but I think it had to do with production runs in 1999?

ALL WIN Q3131 IS GOOD! Have have shot tons of 1999 several lots no problem!

Even Chuck Santoes  50yrd ZERO!!!! told me at one time HE never had any types of problems with 1999!

I have still 1999 Q3131 I saved because its a bit hotter than the Q3131A

Q3131A is good as well!

Im glad WIN is making it in the good ole USA 3270fps! I wish there was MORE Q3131

What happened then? Back around 2000-2002 I was posting here with my problems I had with Q3131, eveybody said it was crap. But praised Q3131A/IMI M193. Loads of complaints about short stroking. Anybody here remember this?

i just bought 300 rounds of q3131 with headstamps from 04 and 05 mixed havnt shot any yet but when i do ill let you know.

Its all bullshit! Im telling you that there is nothing wrong with Q3131!

ther has been some reports  that Lots of 1999 were to Hot!

I have some 1999 and shot alot of it never any trouble! Ive shot it for years and years

Even CHUCK SANTOSE the 50 yard zero guy Told me that He never ever had any problems with 1999 Q3131    

Myself Id rather have US made M193 AMERICAN MADE!!!!

rather than IMI wich is also good and nothing wrong I got some myself

Not exactly bullshit. I couldnt get this stuff to shoot in my AR. Its a DCM model which has a tighter 223 rem chamber. The Federal AE and good mil surplus stuff worked fine, but Q3131 wouldnt even cycle, nothin but short stroke.

Is there anybody here who has the same happen or is it just my gun?

Don't shoot 5.56 in a .223 gun. It's bad juju.

The problems in 1999 were not BS.

That is correct.  SOME lots were hot some were not.

Neither you nor Chuck has shot rounds from every Lot made in 1999.  There are lots that were way too hot (lot numbers are listed in the Ammo FAQ on MD-AR15.com).  I've shot good Q3131 from 1999 and I've shot BAD Q3131 made in 1999.

If you head to the Documents section of MD-AR15.com you'll find spreadsheets of various chrony tests I've done of ammo.  One of them is from a 'Hot Lot' (PN02) from 1999.  That lot would consistantly pop primers and have extreamly high MV readings (averaged 100fps FASTER than spec - some rounds were as much as 140fps too fast - even the slowest round was 29fps faster than spec).

Myself Id rather have US made M193 AMERICAN MADE!!!!

Given the consistancy I've found with the IMI I'd rather have it.  I've also found the American made brass seems to be softer and builds up more flakes under the extractor.

I was on another site and was suprised to come across this:

http://www.thegunzone.com/556v223.html

According to the page the Winchester Q3131 is exactly the same as the M193 produced for the military under contract from the US gov. It also states that Q3131A is also the same, produced by IMI as a subcontractor for Winchester.

Now, I knew they were similar, but didnt think they were one in the same.

Forest !

The Bullshit was about Q3131 not  in specs! wasnt speaking of 1999 Q3131!


I did say there has been reports of 1999 lots that were TO HOT!!!

And you are RIGHT I have Not shot EVERY LOT! But did ask Winchester about it and they Denied it?
thats because I have a lot that was listed! I forgot the lot number because I put them all on bandoliers?
PCF or something like that

Gota go my PP/Wolf just came! going to check out!!

BTW I didnt say IMI was Bullshit I even said if ya look its good stuff I got some

and as far as USA made I like to support AMERICANS when possible!

Sorry if I mixed my words it happens alot?

Quoted: ...But did ask Winchester about it and they Denied it?

Did you honestly think they would admit to putting out batches of overloaded ammo?
