I'm curious, anyone else out there tried this "junky" ammo?  I say this because I recently went to the range with 3 boxes of this stuff.  Had a lot of problems with this ammo.  Jammed up my rifle like crazy!  Every other shot was a jam and misfeed.  Primers were being blown off and jamming the internals of my Colt.  

Is this ammo known to be made "over pressure"???  I'm worried that maybe it may have damaged my Colt.  When I told the shop that sold me the stuff about the incident they were shocked.  They pulled the stuff of the shelf.  They told me to bring in the rifle and the spent casings and the blown off primers for their inspection.  I will on wed night...

Has anyone out there had the same problems with Olympic SS109 in 62gr?  I hope I didn't mess my Colt up.  I did fire about 50 rounds of the stuff until I finally told myself, "Something is not right w/this ammo"  I did blast off 25rds of Winchester Q3131A with NO problems.  So it has to be an ammo issue.

Comments, advice?

You could take a look at the 3rd posting tacked at the top of this forum, or you could take a look over the next 3 or 4 pages, or you could use the search function.

Olympic has been discussed repeatedly as has their failure to address or respond to the issue.

M4WU, I answered you in my post, but I'll leave you one here too.  The rifle is pretty tough and shouldn't be hurt (hopefully).  Most of the problems you described were the same as mine except for the primers.  I didn't have any blow outs.  The rifle I'm carrying is a new DPMS A2 that I built out due to wanting the 1/7.  I was not in good humor either, but got on here at the office and found a whole herd of other people had problems as well.  I cleaned the flakey ash out of the bolt carrier, loaded up with new ammo and and fired 40 more rnds (in addition to the full mag at the end of my shoot yesterday) with good clean US ammo to make sure the gun was good to go.  Runs like like a crack head with a new $20.00 (very good).

Thanks for the comments guys, I did try to access the above topic on Olympic but it doesn't work for some reason.  I'll try again later.

The guy at the shop still wants me to bring my Colt back for inspection.  I did do a cleaning after my range session and found a lot of that powder and whatever it may be all inside the bolt and carrier.  I fired 25 rounds of Q3131A through my Colt with no problems so I think my Rifle is fine.  But hey, if they want to see it I'll bring it in for inspection.

I'll try to read the above post - does anyone have any other suggestions for 62gr ammo?

I picked up several hundred rounds of it from the local gunshop last year.

It all ran fine.  Chronoed at Military (M855) velocity, and the extream spread for 30 rounds (65.62fps) was almost HALF of the extream spread for Federal XM193 I tested.

YMMV

I guess I'm one of the lucky ones. I have shot a couple of boxes of Olympic SS109, with no problems of any kind. I also got M855 velocities out of it (near 3100 fps) with no signs of overpressure.

Another source of SS109 would be the S&B stuff (which I also have shot with no problems), but some people seem to have had bad experiences with this one as well. If you can find it, the Ingman (Bosnian) black tipped SS109 seems to be very good. And of course, for the real deal (M855), try IMI. That one goes for about $8 for 30 rounds, which is not that bad, and you would be getting top quality ammo.
