Default Accurate factory 5.56 ammo

What are some good choices for accurate factory 5.56 ammo?

I have a Rock River national match rifle, 20” 1 in 8 twist barrel, .223 Wylde chamber.

I don’t reload, and have been shooting federal xm193 55 grain ammo because it is affordable. I mostly shoot at 100 and 200 yards at sr-1 and sr targets, and generally shoot 40 round simulated matches when I go to the range, 10 slow prone, 10 rapid prone, 10 rapid sitting, 10 slow standing. I score in the 340-360 range. I suspect that there are more expensive ammo choices that would help me pick up a few more points.

Any suggestions? It wouldn’t be my regular ammo, but I’d like to see how much I might be missing vs “match grade” or good hand loaded ammo.

Or does ammo not make that much of a difference until you get I. The 300 and 600 yard distances?

Out of that rifle especially, better ammo will definitely make a difference, at all distances. The 55gr FMJ just wasn't intended for great accuracy.

Try IMI "Razorcore" either 69gr or 77gr. IIRC both are loaded with Sierra Matchkings. Those bullets are exactly what your RRA was built to shoot.

SG Ammo (no affiliation) is having a sale right now, including IMI 77gr for $309/500 plus shipping. That's a pretty decent price. It's great ammo, and the brass is good too (for reloading).

If any of the dealers in your area stock Black Hills(either new or reman.) in any match bullet load it will give you a good idea. I have used 69gr. and 77 gr. with good results. The fact is that to get the best out of your rifle at a price you can afford you will have to think about reloading. One of the places you might look is BassPro or Cabela's,. I have seen Black Hills in Cabela's. HTH GB

That's great! Thank you for posting!

A lot of that IMI 77 gr is WAY hot for match type shooting. It may use a match bullet, but it is loaded for people, not targets.

Federal Gold Medal Match is the gold standard (sorry about the pun) of accurate ammo.

Some small producers also do nice match load ammo.

Why should that matter? Cartridges don't become any more or less accurate depending on whether they're fired at paper targets or some other kind of more "interactive" target. The rifle OP is shooting certainly won't care either. Either the rifle/ammo combo produces acceptable groups on target, or it doesn't.

There are several threads over at US Rifle Teams about the various IMI offerings. Numerous match shooters have tried it, most reporting good results. I have personally shot several different varieties of it, including out to 600 yards, and it compares well against my own reloads (which are, of course, cheaper). I keep a can in the truck "just in case" I drive to a match and either forget my regular ammo, need to loan some out, or whatnot.

I strongly disagree! The IMI razorcore ammo is a great deal for match quality ammo. It can be found for 50 cents a round shipped occasionally at Midway.

It can easily shoot 10x clean on an SR target at 200 yards from prone with sling. Some very good shooters are running it at 200 and 300 yards. It would likely be competitive with other 77 grain loads at 600 yards.

I've run through about 1000 rounds of it so far and have another 1000 to go. I've used it for practice and local/reduced matches with great results (298 out of 300 for CMP modern military). The brass is good quality too. I would shoot it in place of my handloads without concerns.

Too hot for match type shooting? Pretty sure the AMU runs scorching hot loads, especially at 600...

Thanks for the input all.

The ar15.com link is great.

I've been pleased with IMI 55 grain xm193 in the past, and was wondering about the 77 grain. I ordered a case of that from SG.

I've got some black hills that I'm gonna try, and SG had 50 round boxes of Fiocci 55 grain ammo (not the Exacta match king ammo) for .28 a round, so I picked up some of that for comparison with the federal xm193.

going from an entry level Delton AR to the RRA National match made for a noticeable increase in accuracy, so I'm wondering what some better ammo will do as an add on.
