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 ordering process and phone check for delivery, ammunition worked well. I had no jams or mis-feeds during range Clean shots on target at 100 yards with my AR. Cleaning was easy with minimum carbon buildup.

As long as you keep your gun clean, this ammo is the best as far as value goes. Hit targets with no issue at 300 yds out of my AR. Will definitely order again!
Jay said:
Great ammo! No issues CANT GO WRONG WITH THIS AMMO! I worn you to clean your rifle ever two or three hundred round. Other than that it is great!!!

This Ammo is great for the way I use it..I shot mostly on the range to 100yd. It shots clean and I never had a misfire and I used many 1000s of rounds using this Ammo. Also the price is very affordable if you shot a lot like I do. Happy shooting hope for BULLSEYE. Dee

I bought 1k rounds of steel cased .223 and it arrived in less than 48 hours. I know you aren’t “supposed” to shoot steel cased out of an ar15, but after about 500 rounds I’ve experienced zero problems. It’s hard to beat 35 cents per round.

Nothing wrong with this ammo, shots straight, and on target. !!!!!!

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.
Ezekiel said:
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.

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!!!!!

It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com
