This ammo has proven to be the most accurate I've found out of a Remy 700 HB with a 1:12 twist. Had almost given up on accuracy with this rifle, but this load yielded 0.7 MOA (100 yds, calm day, off support).

I have bought lots of 1,000 of this ammo 2-3 times. The first lot(s) were good. However, I started getting tons of split case necks about every 10th round with my most recent lot. This was with a 10.5" AR pistol and good quality P-mags. I had my local gunsmith look at the gun, and he couldn't find any issues, so presumably the culprit was the ammo. Not sure if they had some QC issues this year? I haven't written off Fiocci, but I'll probably wait a while until any bad ammo cycles through the market.

Ive been shooting fiocchi 223 amd 9mm for a couple years solely now, never have had a malfunction, bad primer, or defaced/damaged round. Shoots great, burns well, and such a good price for what you get.

Purchased 1000 and reloaded those after shooting. Ammo functioned beyond expectations and reloaded cases performed well too.

I have a bear creek arsenal upper in 223 wild with a 20inch SS slick side charge and man I'm telling you that this stuff shoots 5 shots into 1/2 inch groups all day long, I bought this ammo because it shoots as flat as a 22,250 55 grain bullets do, I've yet to shoot any yotees yet but when I do you guys will be the first to know, I can't wait!!!!!

Ran this ammo thru my Ruger AR with a Banish suppressor on, and everyone was amazed at how quiet it was, and when my target came back in, how accurate. Great ammo, would buy again.

Def said:
This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.
Jack said:
I have always put M193 as offensive/defensive ammo, which is why I purchased it in the first place. I tested 80 rounds at 25, 50, 100, and 300 yards with a Sig M400, it was dead on accurate.
