SH in TX said:
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).

GREAT AMMO AND IT SHOOTS VERY GOOD WITH NO MALFUNCTIONS

Rodge said:
The service was excellent. The performance of the Aguila .223 Rem FMJ ammo is superior to ammo that cost more. It is excellent quality brass and I've not had a single failure to date in over 1250 rounds fired over a three month period.

Ammo.com had the best price per round for the Aguila and also was pleasantly surprised on the ease and quickness of the order and delivery! I'll always shop here first!

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.

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

Gary said:
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!!!!!

NuSparkey said:
Nothing like using good ammo to make you feel good about yourself. Pushed it out to 300 meters and anything off target was probably my jittery finger. Cycled well under rapid fire. I like it!
