What kind of accuracy to expect from the "FBI Load" 5.56 TBBC?

I'm seeing just over 1.5moa to 2+moa out of 3 Noveske 14.5" barrels at 100 yards so I think its capable of the accuracy, not Camp Perry or sniper level like you said, but its capable, at least the lots of it I have and shot. The groups that are closer to 1moa are less frequent than the 2ish moa ones. I've not shot any that produced 3 or more moa. Of course I dont think it's intended to be capable of precision like most of us think of precision is it?

I have over 5000 of the TBBC bullets (guess what I've been doing with my forced time off) and have loaded some decent loads with them using 24.8gr of Vhitavuori N530 (over published max 3048 fps,23ft SD) 25.0gr of WC844 (H335) 24.2gr of WC844 and 23.6gr of 8208xbr. Accuracy is not much better but does seem to be more consistent and those loads are closer to MOA than the factory loads I have (3 different lots).

I've never seen factory seconds rounds or boxes. Don't buy a lot of factory, but what does this factory second fodder sale for on the street?

I would hope an FBI load would produce 2 MOA at WORST. Jeez man. Do they have to run sft points or some shite? Black Hills OTM is the goods for factory IMHO.

It’s not cheap. Especially for stuff that doesn’t make the cut. FBI has a contract for a stated accuracy level. Those lots that don’t make the cut are put on the commercial market.

And JSP are the go to for human threats, it’s not all precision marksmanship.

Why would they want Black Hills OTM? The FBI has stressed barrier-blind performance in their ammunition -- pistol and rifle -- for decades now. Heavy OTMs for all their benefits have their performance severely degraded by intermediate barriers.

JSPs are great rounds for the niche and uses the FBI finds themselves in.

About the only thing OTM bullets are good for is punching paper or steel. There’s a reason end users looking for on target performance that can choose their projectile usually choose something else.

7 rounds (from the same box of 20) of the XM556FBIT3 with a 77gr IMI SMK for reference. These were case gauged after the brand new gun with in spec chamber failed to chamber them. Note the dents at the neck from the force of the BCG trying to close on the out of spec case. The X. It means something. Source is the proverbial internet friend of a friend. They have the job and certs to back up the claim.

I’d be tempted to pull the bullets dump the powder, and resize the cases and reload them.

Or just use the bullets as component bullets if the price was low enough.

I’ve bought thousands of XM loads from Federal over my time as range sergeant. They have all been regular production, not seconds.

As for the original question. No, the 62gr Federal bonded loads (whether the 5.56 specifically mentioned or the LE223T3 loads) are not tack drivers. In my good rifles, I see 5 shot groups at 100yds going from the occasional 1” to the more common 2.5“ to 3”. This is fine for most all of the police engagements that will occur, especially with patrol officers using red dots. Were I wanting more precision, I would look at some of the Black Hills loads, especially with the Barnes TSX bullets. I like the Black Hills 62gr TSX round for personal use. But am using the LE223Ts round for duty as it is department issued.

I have also tried the Ranger 64gr and found it to be on par for accuracy with the Federal bonded loads.

As a bonus, the LE223T3 loads have a nickel case so I can immediately know whether the magazine is filled with range fodder or carry ammo.

The emphasis on these rounds (both Federal and Ranger) is on what they do when they hit the ‘combat scoring’ zone on a bad guy. They are both excellent in that regard, both with and without barriers.



In the end, we tend to over think this. Here is a simple 4 step process...

1) Buy samples of a few rounds that perform well when they hit the target (Refer to FBI tests as a good resource, available on letter head from Quantico, or study Molon’s posts).

2) Shoot these sample loads to see which ones are acceptable through your rifle as far as grouping.

3) Buy more of those.

4) Buy similar weight FMJ rounds and practice.

Number 4 is far and away the most important.

Can you confirm you're loading 24.2 and 25.0 grains of 844 or is the second 844 load a typo? 842 maybe? Thanks.

They have have been 1.5-2.25 moa for me and my guns. I would recommend the gold dot offering in 62/64 grain and the 75 grain if accurate barrier blind ammo is the goal and you can take a slight velocity hit.
