Best 20 groups: .657 in. // Best 10 groups: .510 in.
If football is a game of inches, then precision rifle is a game of thousandths of an inch. As you can see here, the Nosler 140-grain RDF edged out the Federal 140-grain SMK in the 20-group aggregate by .035 in. and was just nine-thousandths (.009 in) larger than the Federal load when measuring the top 10 groups. At these dimensions, we are literally splitting hairs between the group sizes.
Where the Federal ammunition did better was in its versatility. The four smallest groups with the Nosler 140-grain RDF Creedmoor ammo came from the same rifle: the Accuracy International AT-X, with the groups measuring between .347 and .497 inches. That said, the Nosler’s 10 best groups included four different rifles. In addition to the AI AT-X there was the Proof Tundra (.506 in.), Franchi Momentum Elite (.536 in.), and the Weatherby Backcountry 2.0 (.547 in.). Point being, the Nosler RDF is no one-trick pony either.
For those not familiar with the RDF bullet line, which spans from 70-grain .224-caliber bullets to 300-grain .338s, it was created by Nosler a few years back as their in-house precision rifle bullet. RDF stands for “reduced drag factor,” meaning they squeeze as high a B.C. value from each bullet as possible through the bullets’ co*pound ogives and long boattails.
In the co*petitive shooting world, the RDF’s are a bit of a sleeper. Bullets from Berger and Hornady get a lot of attention, but a lot of top shooters are cleaning up with the RDFs as well in the various practical precision rifle co*petitions.
Given the stellar performance of this factory ammo, I don’t think that the RDFs will remain an underdog for long.

Not surprisingly, Hornady’s factory 6.5 Creedmoor ammo performed well, too. I’ve shot the 147-grain ELD-Match bullets in the NRL-Hunter series and placed high in the standings running it through my Proof Switch.
But one thing that this broad-based test revealed is that the 140-grain bullets shot notably better than any of the other 6.5mm bullet weights. In Hornady’s case, the 140s did best, followed by the 143-grain ELD-Xs, and then the 147-grain ELD-Match. Here’s how they stacked up:
Hornady 140-grain ELD-Match: Top 20 groups: .808 in. average // Top 10 groups: .627 in. average
Hornady 143-grain ELD-X: Top 20 groups: .987 in. average // Top 10 groups: .777 in. average
Hornady 147-grain ELD-Match: Top 20 groups: 1.246 in. average // Top 10 groups: .826 in. average
It’s worth noting that the Hornady 143-grain ELD-X was the most accurate hunting bullet among the 6.5 Creedmoor ammo we shot. I have have killed several elk as well as a bunch of whitetails, mule deer, and antelope with this load and can attest to its excellent terminal performance. Understand that the bullet is designed to upset at longer distances, meaning lower impact velocities. Because of this, the ELD-X tends to lose a significant portion of its weight as it penetrates, especially with closer hits when it still carries a lot of velocity. So, it is less likely to penetrate through an animal and leave two leaky holes, but dead is still dead.
Now, curiously, in the one 6.5 PRC rifle in the test, the Seekins Havak HIT, the 147-grain ELD-Match averaged .639 in. with its 10 best five-shot groups, which just goes to show you how important it is to try a variety of loads in your rifle to land on the best accuracy.
Another good performer in the test was Winchester’s 140-grain BTHP load. The top 20 groups with this 140-grain load averaged 1.122 in., while the 10 best groups averaged .868 in.
